Fan-out wafer-level packaging(FOWLP)provides a scalable and cost-effective pathway for heterogeneous electronic–photonic integration in co-packaged optical systems.As per-lane data rates advance beyond 200 Gbps,the electrical performance of the package,especially the vertical through-package interconnects,becomes a critical bottleneck,directly limiting achievable bandwidth density and signal integrity.In this work,we present a 3D optical engine(OE)platform,a design methodology,and a comparative study of multiple through-package via technologies,including through-silicon vias,through-mold vias(TMV s),embedded substrate vias(e Bar),and prefabricated through-glass vias(TGVs).Comprehensive electromagnetic simulations and experimental measurements demonstrate that prefabricated TGVs offer superior high-frequency performance,combining low insertion loss,fine pitch,and high bandwidth density enabled by the ultra-low dielectric loss of glass substrates.Leveraging this platform,a 3D FOWLP-based OE architecture with electrical bandwidth margin for future 400-Gbps-per-lane-class signaling is designed.Wafer-level electrical continuity,optical uniformity,thermo-mechanical behavior,and thermal cycling reliability are systematically evaluated,confirming robust manufacturability and reliability.In addition,an electronic–photonic co-design process design kit is developed.Together,these studies establish prefabricated TGV-enabled 3D FOWLP as a scalable and design-ready integration platform for next-generation high-bandwidth co-packaged optical systems. 展开更多

This study employed integrated multi-omics approaches to elucidate,from the perspective of amino acid metabolism,the adaptive mechanism of Penicillium digitatum under modified atmosphere packaging(MAP)conditions.Comparative analysis of natural air(Air),controlled atmosphere(CA),and MAP treatments revealed that MAP upregulated the expression of the hercynylcysteine S-oxide synthase(HCSOS),aldehyde dehydrogenase(ALDH),and monoamine oxidase(MAO)genes,thereby enhancing histidine-derived ergothioneine and methionine levels,and subsequently boosting glutathione-mediated redox homeostasis.Meanwhile,MAP induced the expression of the dihydroxyacid dehydratase(DHAD),saccharopine dehydrogenase(SDH),and arginosuccinate lyase(ASL)genes,redirecting valine,lysine,and arginine into the tricarboxylic acid(TCA)cycle to fuel ATP production.MAP also enhanced ASL-mediated arginine degradation and urea cycle activity,reducing arginine accumulation when compared to CA treatment.In contrast,while MAP induced upregulated expression of the pyrroline-5-carboxylate dehydrogenase(P5CDH)and D-amino acid oxidase(DAAO)genes,CA treatment promoted proline accumulation,reflecting stress-specific metabolic flexibility.Collectively,these findings demonstrate that MAP triggers transcriptional reprogramming of amino acid metabolism to coordinate oxidative defense,energy generation,and osmotic balance.By modulating these metabolic pathways and regulatory genes under MAP conditions,fungal adaptability can be disrupted.Hence,this study provides a promising strategy for suppressing green mold development,extending the postharvest shelf life,and improving the quality of fruits and vegetables. 展开更多

Corn starch(CS)is a renewable,biodegradable polysaccharide valued for its film-forming ability,yet native CS films exhibit lowmechanical strength,highwater sensitivity,and limited thermal stability.This study improves CS-based films by blending with poly(vinyl alcohol)(PVA)or glycerol(GLY)and using citric acid(CA)as a green,non-toxic cross-linker.Composite films were prepared by casting CS–PVA or CS-GLY with CA at 0%-0.20%(w/w of starch).The influence of CA on physicochemical,mechanical,optical,thermal,and water barrier properties was evaluated.CA crosslinking markedly enhanced the tensile strength,water resistance,and thermal stability of CS-PVA films while increasing transparency in CS–GLY films.At 0.20%CA,the composite achieved 34.99MPa tensile strength,reducedwater vapor permeability,andminimized water uptake.FTIR confirmed ester bond formation between CAand hydroxyl groups of CS,PVA,and GLY,whereas thermal analysis showed higher decomposition temperatures and lower weight loss in crosslinked films.Increasing CA levels also decreased opacity and improved light transmittance,indicating greater homogeneity and reduced crystallinity.This dual-polymer matrix combined with a natural crosslinking strategy provides a sustainable route to high-performance,biodegradable CS-based packaging materials. 展开更多

Driven by the'dual carbon'strategy and the imperative of a circular economy,food packaging is undergoing a ternary upgrade.In this study,mulberry anthocyanin extract(MAE)was upcycled into a natural,dual-function active principle that concurrently delivers antioxidant capacity and ultraviolet(UV)barrier activity.It was incorporated with an edible sodium alginate-gelatin(SG)based film to engineer a next-generation biodegradable antioxidant film.The dose-dependent impacts of MAE on the film's mechanical signature,radical-scavenging efficacy,optical performance,and practical utility in fish oil packaging were systematically examined.MAE obtained from a residue of mulberry juice fermentation had 296.86 mg/g total polyphenols and 146.50 mg/g anthocyanins,primarily cyanidin-3-glucoside and cyanidin-3-rutinoside.When 0.2 mg/mL MAE(SG-2MAE)was added,the tensile strength of SG films increased from 48.33 to 50.98 MPa.When 0.4 mg/mL MAE was incorporated,the antioxidant activity of SG-4MAE film against 2,2'-biazido-bis-3-ethylbenzothiazoline-6-sulfonic acid(ABTS)increased by 158%,whereas transmittance(600 nm)decreased by 33.7%,indicating enhanced UV blocking.When applied for packaging fish oil,the SG-MAE film delayed oxidation better than the unpackaged sample after 4 weeks'storage by directly blocking oxygen,releasing antioxidant constituents,and adsorbing residual oxygen.In summary,SG-MAE films showed excellent comprehensive properties and high antioxidant properties,and could be used as active packaging materials for fish oil. 展开更多

Biobased biodegradable plastics have gained increasing attention as sustainable alternatives to petroleum-based materials in food packaging,offering biodegradability,renewability,and reduced environmental impact.This review adopts a narrative review approach,integrating studies published between 2015 and 2025 from major databases to critically evaluate the recent advances,feasibility,and limitations of biobased biodegradable plastics in food packaging.Literature was thematically analyzed by material type and functional enhancement to assess their feasibility and limitations for sustainable packaging applications.Recent advances have focused on enhancing their mechanical,barrier,and functional properties through polymer blending,nanoparticle reinforcement,and incorporation of natural bioactive agents.Starch-based bioplastics,derived from renewable sources such as corn and cassava,have been improved by blending with polylactic acid(PLA)or polybutylene succinate(PBS)and reinforcing with nanocellulose or silica to enhance flexibility,strength,and thermal stability.Incorporating plant extracts and polyphenols has added antioxidant and antimicrobial functions.PLA-based films have benefited from nanoparticle fillers like zinc oxide and lignin nanoparticles,and the integration of bioactive compounds such as tea polyphenols and hop extract has enabled multifunctional,intelligent packaging with controlled release and UV protection.Polyhydroxyalkanoates(PHAs),producedmicrobially,have been functionalizedwith tannins,ferulic acid,and other natural agents to achieve high antioxidant,antibacterial,and UV-blocking performance,while multilayer coatings have improved moisture and gas resistance.PBS composites have been enhanced using nanofillers like silver or magnesium oxide and natural additives such as quercetin and essential oils,thereby improving durability and bioactivity.Emerging materials,including chitosan-,protein-,and polysaccharide-based films,show excellent film-forming ability and compatibility with natural antimicrobials;smart systems with pH-sensing and UV-shielding functions further extend food shelf life.Despite remaining challenges such as cost,moisture sensitivity,limited scalability,and potential competition with food resources,recent progress demonstrates that biobased biodegradable plastics hold strong potential to advance sustainable,high-performance food packaging,particularly when waste is valorized.Future research should focus on improving the cost-effectiveness,scalability,and moisture resistance of biobased biodegradable plastics,while advancing waste-derived feedstocks,multifunctional smart packaging,and comprehensive life cycle assessments to ensure sustainable and practical food packaging solutions. 展开更多

We presents a novel prism-coupled packaging strategy for whispering gallery mode resonators(WGMRs).Utilizing an all-solid-state optical adhesive process combined with active temperature control and hermetic sealing,the proposed package scheme exhibits exceptional long-term stability and environmental robustness.The standalone WGMR module was fully characterized,demonstrating a temperature sensitivity below 10−7/℃and a low-frequency Z-axis acceleration sensitivity below 10−10/g.Furthermore,the application of this module was explored as a stable optical frequency reference and a nonlinear photonic platform,achieving a short-term frequency stability of 2×10−13at 2 ms and generating Kerr soliton microcombs with a pump power of 100 mW.This compact,robust,and stable packaging solution significantly enhances the immediate applicability of WGMRs in real-world applications such as narrow-linewidth lasers and portable microcombs,thereby facilitating the transition of WGMR technology from laboratory research to practical deployment. 展开更多

Owing to superior breakdown voltage and excellent robustness,the betagallium oxide(β-Ga2O3)power device has emerged as a pivotal research frontier in power electronics.Although advanced packaging strategies,including nanosilver paste sintering,alumina direct bond copper(DBC)substrates,and flipchip structures,have been adopted to mitigate the intrinsic low thermal conductivity ofβ-Ga2O3.However,a further reduction in the thermal resistance while maintaining high reliability remains a challenge.This study introduces a novel packaging methodology that synergistically integrates nano-silver films with aluminum nitride active metal brazing(AMB-AlN)substrates,achieving an ultra-low junction-to-case thermal resistance.By comprehensive reliability assessments onβ-Ga2O3 Schottky barrier diodes(SBDs)and hetero-junction diodes(HJDs),the results demonstrate that the SBDs and HJDs exhibit surge current densities of 0.876 kA/cm2 and 0.778 kA/cm2,respectively,which represents a significant advancement in device performance benchmarks.These advancements provide critical insights into packaging design for highreliability ultrawide bandgap semiconductor systems. 展开更多

This study aims to synthesise,characterise and evaluate the performance characteristics of packaging films based on biodegradable natural resources incorporated with nanoparticles.Particularly,it is focused on the valorisation of the fibers from the underexploited Lonchocarpus cyanescens plant fromWest Africa as raw renewable lignocellulosebiomassmaterial source for the productionof carboxymethylcellulose(CMC).To this end,biodegradable films were prepared from CMC derived from the fibers of the Lonchocarpus cyanescens plant,and collagen.In order to improve the properties of these films,in particular their mechanical and humidity resistance and their ability to fight microbes,silver nanoparticles(Ag NPs),titanium dioxide nanoparticles(TiO2 NPs),as well as heterostructure Ag@TiO2 nanocomposite were incorporated.The different products obtained were characterised by differentmethods,including DLS,UV-VIS,SEM,contact angle,UTM,absorption and antimicrobial activity tests.The results show that the hybrid biocomposite films exhibit good mechanical properties,improved moisture resistance,and a significant antimicrobial effect against certain pathogenic bacteria.In particular,the synergy between Ag and TiO2 nanoparticles in the heterostructure Ag@TiO2 nanocomposite optimized the performance characteristics of the packaging films,particularly in terms of mechanical properties with a maximum stress of 38.77 MPa and a strain of 9%,low water absorption reaching 50% at 48 h,improved hydrophobic behaviorwith contact angle of 87°,and antimicrobial resistance compared with the control film without nanoparticles.This work highlights the valorisation of an underexploitedWest African local plant and contributes to the search for sustainable solutions for food packaging. 展开更多

This study evaluated the spoilage potential of dominant bacteria(Shewanella putrefaciens and Pseudomonas fluorescens)on the effect of the deterioration of adenosine triphosphate-related compounds in refrigerated large yellow croaker fillets under air-packaging and modified atmosphere packaging(MAP).In this work,the total viable count(TVC),adenosine triphosphate-related compounds,and related enzyme activities were characterized in refrigerated large yellow croaker fillets inoculated spoilage bacteria.Macrogenomic analysis was employed to explore the contribution of packaging methods to metabolic pathways and related enzymes.The result demonstrated that the TVC of S.putrefaciens reached 7.85(lg(CFU/g))on day 21,exhibiting stronger potential for growth in MAP.The results showed that S.putrefaciens had a higher potential to degrade adenosine triphosphate-related compounds and produce related enzyme activities under MAP conditions than P.fluorescens.The initial value of hypoxanthine riboside(HxR)during storage in the air processing(AIRP)group was 0.76μmol/g,which reached a peak on day 3(1.71μmol/g),and the level of HxR decreased to 0.38μmol/g on day 12.The MAP group showed a similar trend to the AIRP group,but the peak appeared later than the AIRP group.The ability to degrade HxR in S.putrefaciens exhibited a significant difference in air packaging.In addition,macrogenomic analysis indicated that the degradation of inosine monophosphate(IMP)was primarily performed by 5'-nucleotidase(5'-NT).This study enhances our comprehension of the role of microorganisms in fish spoilage and provides valuable insights for the development of novel preservation methods. 展开更多

Active packaging systems,which react either with the environment or with the food itself,are a new addition to traditional food packaging to improve food preservation.Consumer demand for natural foods with minimal processing has resulted in the integration of natural compounds,including catechins,which are polyphenolic compounds abundant in numerous sources like green tea,cocoa,berries,etc.These compounds are considered bioactive agents due to their high antioxidant,antimicrobial,and anti-inflammatory potential.This review comprehensively analyzes catechin-based active packaging,covering catechin sources,physicochemical and biological properties,and fabrication techniques.It also evaluates the functional properties of these systems and their practical applications in food packaging.The main fabrication techniques,such as solvent casting,electrospinning,and melt processing are used,and each method has specific advantages in incorporating catechins into polymer matrices.The properties of packaging film,such as free radical scavenging,prevention of foodborne pathogens,better UV-blocking activity,and improved thermal stability are discussed extensively.Numerous studies have exhibited that catechin-based active film significantly helps to extend the shelf life of various food products such as meat,seafood,fresh produce,and dairy.Challenges such as the thermal instability of catechins,bitterness after consumption,industrial production,and safety concerns related to migration and toxicity still need to be addressed.The use of encapsulation methods and providing proper regulatory guidelines can create a sustainable and effective solution in catechin-based active packaging. 展开更多

The present study monitored bacterial succession,physicochemical properties,and volatile organic compounds(VOCs)changes in smoked chicken legs with modified atmosphere packaging(MAP,60% CO2 and 40%N2)during a 25-day storage period at 4℃.After 15 days of storage,S erratia proteamaculans and Pseudomonas fragi became the predominant bacteria.Furthermore,physicochemical properties changed significantly,as evidenced by an increase in thiobarbituric acid reactive substances and b*(yellowness)value,and a decrease in hardness.A total of 65 VOCs were identified during storage.Correlation between bacterial succession and quality indicators(including VOCs and physicochemical properties)allowed the identification of 26 core dominant bacteria,including S.proteamaculans,Psychrobacter alimentarius,Pseudomonas putida,and Pseudomonas poae,which were positively related to spoilage VOCs(e.g.,1-octen-3-ol,1-pentanol,and 3-methyl-1-butanol)and could be defined as specific spoilage organisms(SSOs).The results of this study provide a systematic approach to predict SSOs in smoked chicken legs during storage,which can also provide a basis for product safety. 展开更多

Petrochemical plastics are widely used for food protection and preservation;however,they exhibit poor biodegradability,resisting natural degradation through physical,chemical,or enzymatic processes.As a sustainable alternative to conventional plastic packaging,edible films offer effective barriers against moisture,gases,and microbial contamination while being biodegradable,biocompatible,and environmentally friendly.In this study,novel active food packaging materials(in film form)were developed by incorporating starch,carrageenan,nanocellulose(NC),Aloe vera,and hibiscus flower extract.The effects of varying the matrix composition(26.5–73.5 wt.%starch/carrageenan),NC concentration(2.77-17.07 wt.%),and particle type(fibers or crystals)on the film structure and characteristics were analyzed using various methods.Scanning electron microscopy demonstrated good homogeneity and effective dispersion of NC within the blendmatrix.An increased carrageenan content in the filmimproved wettability,moisture absorption,solubility,and water vapor permeability.The mechanical properties of the films were enhanced by NC incorporation and higher carrageenan content.The developed films also exhibited effective UV radiation barriers and biodegradability.Films with low carrageenan content(less than 33.3%)and high NC content(7%,10% crystals or 10%,15% fibers)exhibited optimal properties,including enhanced water resistance,hydrophobicity,and mechanical strength,along with reduced water vapor permeability.However,the high water solubility and moisture absorption(above 55% and 14%,respectively)indicated their unsuitability as packaging materials for food products with wet surfaces and high humidity.The results suggest that these films are well suited for use as edible food packaging for fruits and vegetables. 展开更多

Technological advancements and the emphasis on reducing the use of hazardous materials,such as Pb,have led to the widely use of Sn-based Pb-free solder in advanced packaging technology.With the miniaturization of solder joints,Sn-based micro solder joints often contain single or limitedβ-Sn grains.The strong anisotropy ofβ-Sn,which is significantly correlated with the reliability of the micro solder joints during service,requires the development of methods for controlling the orientations of theseβ-Sn grains.In this review,we focus on the anisotropy of theβ-Sn grains in micro solder joints and the interactions betweenβ-Sn grain orientation and reliability issues concerning electromigration(EM),thermomigration(TM),EM+TM,corrosion process,tensile and shear creep behavior,thermal cycling(TC)and cryogenic temperature.Furthermore,we summarize the strategies for controlling theβ-Sn orientation in micro solder joints.The methods include changing the solder joint size and composition,adding additives,nucleating on specific substrates and interfacial intermetallic compounds,with the aid of external loads during solidification process and introducing heredity effect of theβ-Sn texture during multi-reflow.Finally,the{101}and{301}twinning models with∼60°rotations about a common〈100〉are adopted to explain the mechanism ofβ-Sn grain nucleation and morphology.The shortcomings of the existing methods and the further potential for the development in the field are discussed to promote the application of Pb-free solders in advanced packaging. 展开更多

Modern warfare demands weapons capable of penetrating substantial structures,which presents sig-nificant challenges to the reliability of the electronic devices that are crucial to the weapon's perfor-mance.Due to miniaturization of electronic components,it is challenging to directly measure or numerically predict the mechanical response of small-sized critical interconnections in board-level packaging structures to ensure the mechanical reliability of electronic devices in projectiles under harsh working conditions.To address this issue,an indirect measurement method using the Bayesian regularization-based load identification was proposed in this study based on finite element(FE)pre-dictions to estimate the load applied on critical interconnections of board-level packaging structures during the process of projectile penetration.For predicting the high-strain-rate penetration process,an FE model was established with elasto-plastic constitutive models of the representative packaging ma-terials(that is,solder material and epoxy molding compound)in which material constitutive parameters were calibrated against the experimental results by using the split-Hopkinson pressure bar.As the impact-induced dynamic bending of the printed circuit board resulted in an alternating tensile-compressive loading on the solder joints during penetration,the corner solder joints in the edge re-gions experience the highest S11 and strain,making them more prone to failure.Based on FE predictions at different structural scales,an improved Bayesian method based on augmented Tikhonov regulariza-tion was theoretically proposed to address the issues of ill-posed matrix inversion and noise sensitivity in the load identification at the critical solder joints.By incorporating a wavelet thresholding technique,the method resolves the problem of poor load identification accuracy at high noise levels.The proposed method achieves satisfactorily small relative errors and high correlation coefficients in identifying the mechanical response of local interconnections in board-level packaging structures,while significantly balancing the smoothness of response curves with the accuracy of peak identification.At medium and low noise levels,the relative error is less than 6%,while it is less than 10%at high noise levels.The proposed method provides an effective indirect approach for the boundary conditions of localized solder joints during the projectile penetration process,and its philosophy can be readily extended to other scenarios of multiscale analysis for highly nonlinear materials and structures under extreme loading conditions. 展开更多

The extensive use of polymeric materials in single-use packaging has driven the need to develop biodegradable alternatives.This study investigates the incorporation of graphene oxide(GO)and Moringa oleifera seed oil(MOSO)into a gelatin matrix to create polymer films and evaluate their potential as active packaging materials.The properties of these films were evaluated using structural,thermal,mechanical,optical,and physicochemical methods to determine their suitability for food packaging applications.The results showed that GO and MOSO were homogeneously dispersed in the gelatin matrix,forming colloidal particles(around 5μm in diameter).The addition of GO increased opacity by approximately 20 times the base value while MOSO affected light transmittance without impacting opacity.Mechanical properties were affected differently,GO acted as a crosslinking agent reducing elongation and increasing tensile strength at break,on the other hand MOSO acted as a plasticizer,making films more plastic increasing elongation a 30%.These effects counteracted each other,and similar behavior was recorded in differential scanning calorimetry.The films exhibited an improved water vapor resistance,which is crucial for food packaging.These findings indicate that the incorporation of GO and MOSO into a gelatin matrix may produce biodegradable polymer films with enhanced properties,suitable for active packaging in the food industry. 展开更多

The primary purpose of packaging is to protect and conserve the products inside it.When food is packaged,it is protected from mechanical damage;physiochemical changes brought on by sunlight,oxygen,moisture,and aroma;and biological changes brought on by pests and microbes.Research and food industry sectors are striving to find more biodegradable and renewable natural-source materials to replace synthetic packaging,owing to their adverse environmental effects.Among such natural resources,alginate is a biodegradable packaging material extracted from brown algae.Its gelling properties have made alginate promising for packaging.Alginate,as an edible coating or film,holds promise in maintaining dehydration,regulating barrier respiration,enhanced aesthetics,improved mechanical properties,and many more features for the protection or enhancement of quality and extending the shelf life of fruits,vegetables,cheese,poultry,seafood,and meats.This paper presents information in a concise form about the significance of alginate that may help researchers understand the concept of the technique of coating and film formation,as well as the structure,physical,and chemical properties and the incorporation of active substances,such as antifungal and antioxidant agents.The current work also focuses on future trends and insights into the performance enhancement of alginate as a potential coating and film-forming agent. 展开更多
