Diamond,an ultrawide-bandgap semiconductor material,is promising for solar-blind ultraviolet photodetectors in extreme environments.However,when exposed to high-temperature conditions,diamond photodetector surfaces are unavoidably terminated with oxygen,leading to low photoresponsivity.To address this limitation,single-crystalline diamond nanowires(DNWs)embedded with platinum(Pt)nanoparticles were developed using Pt film deposition followed by chemical vapor deposition(CVD)homoepitaxial growth.During the CVD,Pt nanoparticles(approximately 20 nm in diameter)undergo dewetting and become uniformly embedded within the single-crystalline DNWs.Photodetectors fabricated with these Pt nanoparticles-embedded DNWs achieve a responsivity of 68.5 A W−1 under 220 nm illumination at room temperature,representing an improvement of approximately 2000 times compared to oxygen-terminated bulk diamond devices.Notably,the responsivity further increases with temperature,reaching an exceptional value of 3098.7 A W−1 at 275℃.This outstanding performance is attributed to the synergistic effects of the one-dimensional nanowire structure,deep-level defects,the localized surface plasmon resonance effects induced by embedded Pt nanoparticles,and localized Schottky junctions at the Pt/diamond interface,which enhance optical absorption,carrier generation,and separation efficiency.These results highlight the significant potential of Pt nanoparticles-embedded DNWs for advanced deep ultraviolet detection in harsh environments,including aerospace,industrial monitoring,and other applications. 展开更多

With increasing drug resistance,Candida infections have posed serious threats to public health.Photodynamic therapy harnesses light to destroy pathomycete,providing a smart strategy for combating of Candida infections.However,due to lack of organelle targeting ability and bad extracellular polymeric substances penetrability,current photosensitizers(PSs)are far from desirable to clean biofilms and fight against drug resistance.Herein,a mitochondrion targeting aggregationinduced emission PS,LIQ-TPA-TZ,was developed for the efficient photodynamic treatment of oral Candida infection.LIQ-TPA-TZ has good singlet oxygen and hydroxyl radical generation ability,which can efficiently kill the Candida guilliermondii(C.guilliermondii)and eradicate the biofilm.It not only causes mitochondrial damage by disruption of mitochondrial respiratory chain and oxidative stress-related gene but also inhibits fungal adhesion and filamentous growth to prevent Candida colonization,mycelia growth and biofilm formation,which is favorable for eliminating the potential drug resistance.In the mouse oropharyngeal Candida biofilm infection model,LIQ-TPA-TZ significantly eliminates infection,alleviates inflammation,and accelerates mucosal defect healing.This study provides a favorable strategy for confronting drug resistance,which may be a potential Candidate for the treatment of Candida infection. 展开更多

BACKGROUND Immunoglobulin G4-related disease(IgG4-RD)is a persistent and progressive autoimmune condition marked by inflammation and fibrotic changes in the affected tissues.Cases of IgG4-RD causing pulmonary lesions are relatively rare,and some may be misdiagnosed as pulmonary tuberculosis.CASE SUMMARY In this report,we present an uncommon instance of IgG4-related lung disease,which was diagnosed through lung tissue biopsy conducted via puncture.A 67-year-old male was hospitalized with a two-month history of cough and sputum production.Chest computed tomography(CT)revealed infiltrative pulmonary tuberculosis in both upper lungs.However,the initial diagnosis was unclear,and the patient received HZRE quadruple therapy for tuberculosis at a local hospital.After 45 days of anti-tuberculosis treatment,the patient's cough and sputum worsened,and he began coughing up blood,prompting transfer to our hospital.Serum tests revealed elevated IgG4 levels.A biopsy of a right lung showed localized fibrous and extensive plasma cell infiltration,with 30-40 IgG4-positive cells per high-power field,and an IgG4/IgG ratio of 40%.These findings led to a diagnosis of IgG4-related lung disease.Following treatment with prednisone and mycophenolate mofetil,follow-up lung CT scans showed significant lesion improvement.CONCLUSION The chest CT findings of IgG4-RD are diverse and nonspecific,often leading to misdiagnosis as pulmonary tuberculosis,especially in primary care settings with limited diagnostic resources.We confirmed the diagnosis of IgG4-related lung disease through histological examination. 展开更多

Accurate recognition of low-contrast targets in complex visual environments is essential for advanced intelligent machine vision systems.Conventional photodetectors often suffer from a weak photoresponse and a linear dependence of photocurrent on light intensity,which restricts their ability to capture low-contrast features and makes them susceptible to noise.Inspired by the adaptive mechanisms of the human visual system,we present a molybdenum disulfide(MoS2)phototransistor with tunable sensitivity,in which the gate stack incorporates a heterostructure diode—composed of O-plasma-treated MoS2 and pristine MoS2—that serves as the photosensitive layer.This configuration enables light-intensity-dependent modulation of the diode’s conductance,which dynamically in turn alters the voltage distribution across the gate dielectric and transistor channel,leading to a significant photoresponse.By modulating the gate voltage,the light response range can be finely tuned,maintaining high sensitivity to low-contrast targets while suppressing noise interference.Compared to conventional photodetectors,the proposed device achieves a 1000-fold improvement in sensitivity for low-contrast signal detection and exhibits significantly enhanced noise immunity.The intelligent machine vision system built on this device demonstrates exceptional performance in detecting low-contrast targets,underscoring its promise for next-generation machine vision applications. 展开更多

Although many emerging new phenomena have been unraveled in two dimensional(2D)materials with long-range spin orderings,the usually low critical temperature in van der Waals(vdW)magnetic material has thus far hindered the related practical applications.Here,we show that ferromagnetism can hold above 300 K in a metallic phase of 1T-CrTe2 down to the ultra-thin limit.It thus makes CrTe2 so far the only known exfoliated ultra-thin vdW magnets with intrinsic long-range magnetic ordering above room temperature.An in-plane room-temperature negative anisotropic magnetoresistance(AMR)was obtained in ultra-thin CrTe2 devices,with a sign change in the AMR at lower temperature,with−0.6%and+5%at 300 and 10 K,respectively.Our findings provide insights into magnetism in ultra-thin CrTe2,expanding the vdW crystals toolbox for future room-temperature spintronic applications. 展开更多

Twisted van der Waals homo-and hetero-structures have aroused great attentions due to their unique physical properties,providing a new platform to explore the novel two-dimensional(2D)condensed matter physics.The robust dependence of phonon vibrations and electronic band structures on the twist angle has been intensively observed in transition metal dichalcogenide(TMD)homo-structures.However,the effects of twist angle on the lattice vibrational properties in the TMD heterostructures have not caused enough attention.Here,we report the distinct evolutions of Raman scattering and the underlying interlayer interactions in the twisted WS2/MoS2 heterostructures.The shifts and linewidths of E2g(Γ)and A1g(Γ)phonon modes are found to be twist angle dependent.In particular,analogous to that of the twisted TMD homostructures,the frequency separations between E2g(Γ)and A1g(Γ)modes of MoS2 and WS2 in the twisted heterostructures varying with twist angle correlate with the interlayer mechanical coupling,essentially originating from the spacing-related repulsion between sulfur atoms.Moreover,the opposite shift behaviors and broadening of A1g(Γ)modes caused by charge transfer are also observed in the twisted heterostructures.The calculated interlayer distances and band alignment of twisted WS2/MoS2 through density functional theory further evidence our interpretations on the roles of the interlayer mechanical coupling and charge transfer in variations of Raman features.Such understanding and controlling of interlayer interaction through the stacking orientation are significant for future optoelectronic device design based on the newly emerged 2D heterostructures. 展开更多

Summary of main observation and con elusion In this work,a new simple and readily synthesized turn-on probe 2-(4-anthracene-9-yl-phenyl)-2H-[l,2,3]triazole-4-carbaldehyde(APTC)was legitimately designed towards homocysteine(Hcy).Moreover,APTC has excellent optical properties such as intramolecular charge transfer(ICT)and aggregation induced emission enhancement(AIEE)characteristics,indicating its extensive application potentiality.What's more,APTC displayed rapid,high selectivity and specificity towards homocysteine over cysteine/glutathione.The detection limit of APTC for Hcy was as low as 2.198×10^-8 mol·L^-1,and the response time was only 5 min.APTC has been successfully applied to detect Hcy in silica gel plates and living cells,which indicates that APTC has good stability and biocompatibility as a selective probe for Hcy.Finally,the mechanism was studied using 1H NMR titration experiments and mass spectrometry. 展开更多

Phagocytosis is a biological process that plays a key role in host defense and tissue homeostasis.Efficient approaches for real-time imaging of phagocytosis are highly desired but limited.Herein,an AIE-active near-infrared fluorescent probe,named TBTCP,was developed for fluorescence lifetime imaging of phagocytosis.TBTCP could selectively label the cell plasma membrane with fast staining,wash-free process,high signal-to-background ratio,and excellent photostability.Cellular membrane statuses under different osmolarities as well as macrophage phagocytosis of bacteria or large silica particles in early stages could be reported by the fluorescence lifetime changes of TBTCP.Compared with current fluorescence imaging methods,which target the bioenvironmental changes in the late phagocytosis stage,this approach detects the changes in the cell membrane,thus giving a faster response to phagocytosis.This article provides a functional tool to report the phagocytic dynamics of macrophages which may greatly contribute to the studies of phagocytic function-related diseases. 展开更多

Semiconductor heterostructures mediated by electrical conductors are very promising for Z-scheme photocatalytic water splitting.In contrast to conventional particulate heterostructures,alternate TiO2and Cu2O film stripes patterned parallel on a fluorine-doped tin oxide(FTO) conductive substrate was fabricated as a model film photocatalyst to study the characteristics of the photogenerated charge transfer process.The Z-scheme transfer process with an effective transport distance of up to 5 μm occurs only in regions distant from the TiO2/Cu2O strip edges through the FTO substrate from the bottom.In contrast,the transfer of charge around their contact regions follows the conventional transfer process through the TiO2/Cu2O strip interface.These results indicate that the Z-scheme transfer process occurring in such a large region dominates the charge transfer processes in the TiO2/FTO/Cu2O pattern film heterostructure.Importantly,unlike the single component film,which is inactive for photocatalytic overall water splitting,the modified TiO2/Cu2O pattern film can induce photocatalytic overall water splitting at a stoichiometric H2/O2 ratio close to 2:1.These findings have significant implications in designing efficient heterostructures by employing a Z-scheme charge transfer process. 展开更多

In our previous study,polyurethane(PU)based multilayer films assembled with weak polyelectrolytes exhibited controllable loading and release properties,but would be decomposed in high salt solution.Herein,a strong polyelectrolyte,poly(styrene sulfonic acid)sodium(PSS),was introduced to fabricate multilayer films.The salt tolerance of the film was investigated by evaluating the loading and release profiles towards model drug in salt solution with different concentrations.Results showed that the release behavior of the film,as well as its loading capacity,can be tuned by varying the salt concentrations.And the film showed a good salt tolerance that can remain integrity even after 6 cycles of drug loading and release in 600 mmol•L−1 NaCl solution.It showed that the salt tolerance of PU based films can be greatly improved through assembling with strong polyelectrolyte. 展开更多

In monolayer group-VI transition metal dichalcogenides(TMDs),valley splitting features have received a lot of attention since it can be potentially utilized for information storing and processing.Among the known two-dimensional(2D)TMDs,monolayer WSe2 or MoSe2 has been mostly selected for excitonic and valleytronic physics studies because of its sharp and well-resolved excitonic spectral features.Meanwhile,their high optical quality leads to a tremendous desire for developing promising WSe2-and MoSe2-based valleytronic devices.Toward this goal,exploring the uniformity of valley features crossing an entire piece of monolayer becomes necessary and critical.Here,we performed the systematic magnetophotoluminescence mapping measurements on mechanically exfoliated monolayer WSe2 and observed unconventional spatial variations of valley splitting.The observed nonuniformity is attributed to the modulated doping,which is probably due to the different distributions of unintentional absorbates across the sample.Such an unexpected doping effect shows the nonnegligible influence on the valley Zeeman splitting of the trion emission(XT)while affecting that of the neutral exciton emission(X0)trivially,evidencing for the large valleytronic sensitivity of the charged exciton.This work not only enriches the understanding of the doping effect on valley splitting but also is meaningful for developing 2D valleytronics. 展开更多

Two-dimensional transition metal dichalcogenides （2D TMDs） possess a tunable excitonic light emission that is sensitive to external conditions such as electric field, strain, and chemical doping. In this work, we reveal the interactions between DNA nucleobases, i.e., adenine （A）, guanine （G）, cytosine （C）, and thymine （T） and monolayer WS2 by investigating the changes in the photoluminescence （PL） emissions of the monolayer WS2 after coating with nucleobase solutions. We found that adenine and guanine exert a clear effect on the PL profile of the monolayer WS2 and cause different PL evolution trends. In contrast, cytosine and thymine have little effect on the PL behavior. To obtain information on the interactions between the DNA bases and WS2, a series of measurements were conducted on adenine-coated WS2 monolayers, as a demonstration. The p-type doping of the WS2 monolayers on the introduction of adenine is clearly shown by both the evolution of the PL spectra and the electrical transport response. Our findings open the door for the development of label-free optical sensing approaches in which the detection signals arise from the tunable excitonic emission of the TMD itself rather than the fluorescence signals of label molecules. This dopant-selective optical response to the DNA nucleobases fills the gaps in previously reported optical biosensing methods and indicates a potential new strategy for DNA sequencing. 展开更多
