Employing decoupling index and industrial structure characteristic bias index methods, this study analyzed the spatial-temporal characteristics of industrial structure transformations and their resulting carbon emissions in the Xuzhou Metropolitan Area from 2000 to 2014, with a focus on their relationships and driving factors. Our research indicates that carbon emission intensity from industrial structures in the Xuzhou Metropolitan Area at first showed an increasing trend, which then decreased. Furthermore, the relationship between emissions and industrial economic growth has been trending toward absolute decoupling. From the perspective of the center-periphery, the Xuzhou Metropolitan Area formed a concentric pattern, where both progress towards low emissions and the level of technological advancement gradually diminished from the center to the periphery. In terms of variation across provinces, the ISCB index in the eastern Henan has decreased the slowest, followed by the southern Shandong and the northern Anhui, with the northern Jiangsu ranking last. During this period, resource-and labor-intensive industries were the primary growth industries in the northern Anhui and the eastern Henan, while labor-intensive industries dominated the southern Shandong and capital-intensive industries dominated the northern Jiangsu. In terms of city types, the spatial pattern for industrial structure indicates that recession resource-based cities had higher carbon emission intensities than mature resource-based cities, followed by non-resource-based cities and regenerative resource-based cities. Generally, the industrial structure in the Xuzhou Metropolitan Area has transformed from being resource-intensive to capital-intensive, and has been trending toward technology-intensive as resource availability has been exploited to exhaustion and then been regenerated. Industrial structure has been the leading factor causing heterogeneity of carbon emission intensities between metropolitan cities. Therefore, the key to optimizing the industrial structure and layout of metropolitan areas is to promote industrial structure transformation and improve the system controlling collaborative industrial development between cities. 展开更多

Land, as a key factor of production, is an appropriate indicator of national and regional economic structure transformation. Land use in the Changjiang （Yangtze） River Basin （CRB） since the 1950s has experienced these changes. Industrialization has been the most powerful force of the change in the regional development of the CRB. Virtually all regional resources were put into this effort to modernize the industrial production and urban construction systems of the CRB whose industrialization and urbanization has been a success story, with impressive structural change in both production and land use. These changes are evident ih modem urban areas, but even more in traditionally rural areas. The regression analysis of regional development in the CRB over an extended period shows that the dominant factor in regional land use change is widespread industrialization in rural areas rather than the expansion of urban area. Thus, urbanization has had a limited influence on land use change in the CRB. A major task in realizing more sustainable land use in the future development of CRB is to relocate industrial activities from rural to urban areas. 展开更多

Scarcity of land resources and transformation of industrial structure is a pair of contradictory elements.We derive the characteristics of land use structure and industrial structure transformation in Xining City using Transformation Coefficient(TC):first,in the period 1999-2000,the land use structure coefficient(θ1) declined by 79.55%,but the overall evolution trend is gentle;second,the transformation coefficient of industrial structure(θ2) tended to decline ceaselessly on the whole,a decrease of 36.09%(overall,the transformation coefficient of industrial structure is slightly greater than the land use structure coefficient);third,the inter-annual variation of the two experienced ups and downs(in the period 1999-2007,the inter-annual variation was great and in the period 2008-2010,the inter-annual variation tended to be gentle).On the basis of autocorrelation and co-integration model,we draw the following conclusions through analysis:first,the land use structure in Xining City plays a role in promoting industrial structure transformation;second,there is a long-term equilibrium relationship between the two.Finally,relevant policy recommendations are put forward for the industrial development in Xining City. 展开更多

Thallium(Tl) is a highly toxic trace metal,is present in various environments,such as soils,waters,and sediments.Hexagonal birnessites(HB),naturally occurring minerals,significantly influence metal geochemical cycling due to their strong ability to adsorb and oxidize toxic metals.Understanding the transformation mechanisms of HB into tunnel structures is crucial for predicting their impact on Tl's environmental fate.This study investigated the reactions between Tl(Ⅰ) and acidic birnessite(AcBi),a common form of HB,under different conditions.Tl(Ⅰ) was added to AcBi systems either as a single dose or in twelve equal increments across a pH range of 2 to 6,under both light and dark conditions.Continuous Tl(Ⅰ) additions at pH 4 transformed over 90 % of AcBi into a 2 × 2tunnel structure,while at pH 6,53 %-75 % transformed.At pH 2,intense proton competition inhibited structural reconfiguration.Single dose addition caused minor structural changes at pH 4 and none transformation at pH2 or 6.Illumination accelerated transformations,likely through photoinduced electron transfers.The oxidation state and adsorption coordination of Tl varied with mineral structure:Tl(Ⅲ) was predominantly found in layered structures,while dehydrated Tl(Ⅰ) dominated in tunnel structures,which retained Tl less effectively.These findings offer new insights into the environmental behaviors of these substances and informs strategies to manage thallium pollution. 展开更多

Under the guidance of national policies,the“coal to gas”project has become one of the important measures to promote the transformation of energy structure in China.Foshan,an important industrial town in Guangdong province,the implementation of the“coal to gas”policy has demonstrated significance for the optimization of the national energy structure.Through the analysis of the change in Foshan’s energy consumption structure and the implementation of the policy,this paper found that there were some challenges in the policy implementation process,such as high economic cost,lagging infrastructure,low social acceptance,and lack of technical personnel.To address this,suggestions are put forward,including increasing financial subsidies,improving laws and regulations,promoting technological innovation,and encouraging social inclusion policies.These recommendations aim to provide guidance and reference for the remaining“coal to gas”projects and the development of clean energy. 展开更多

Zero-dimensional(0D)hybrid copper halides have attracted significant attention owing to their unique photophysical properties and remarkable structural diversity.In this work,two 0D self-assemblies compounds of copper iodide dimers were synthesized,namely,(4-MBTP)2(Cu2I4)0.5I(1)and(4-MBTP)(Cu2I4)0.5(2)(4-MBTP=(4-methylbenzyl)triphenylphosphonium chloride).Compound 1 exhibits blue emission centered at 474 nm,while compound 2 shows yellow emission centered at 559 nm at room temperature.The results combined with crystal structure,spectroscopy analysis,characterization,and theoretical studies reveal that the blue light of compound 1 stems from multiple defect states caused by the presence of I vacancies,while the yellow emission of compound 2 is attributed to through-space charge-transfer(TSCT)and cluster-centered(CC)excited state.Strikingly,the crystal structure can transform from compound 1 into compound 2 with luminescence color change from blue to yellow through treating with methanol.This work provides a structural transformation strategy of hybrid copper halides,as well as realizes the regulation of light emission from defect states to non-defect states,making them feasible candidates for information encryption and optical data storage. 展开更多

Structure transformation is a critical step for SDLO. Diversity of transformation methods and existence of complex data types are major challenges for structure transformation. We have designed and implemented STrans, a well-defined system which provides controllable and comprehensive functionality on structure transformation. Compared to known systems, it has less limitation on data types for transformation. In this paper we give formal definition of the approach STrans transforms data types. We have also designed Transformation Specification Language, a mini language to configure how to transform structures, which can be either manually tuned or generated by compiler. STrans supports three kinds of transformation methods, i.e., splitting, peeling, and pool-splitting, and works well on different combinations of compound data types. STrans is the transformation system used in ASLOP and is well tested for all benchmarks for ASLOR 展开更多

When stereochemically-active-lone-pair(SCALP)cations are introduced into chalcogenide systems,it is beneficial to produce a remarkable second-harmonic generation(SHG)response(deff),but it also causes a narrow band gap(Eg),which ultimately results in negative two-photon and free-carrier absorption.Hence,how to obtain a wide Eg(>2.33 eV)while maintaining a strong deffremains a significant challenge in this domain.In this work,Rb is partially replaced by SCALP Pb in the known ternary centrosymmetric(CS)Rb3PS4(space group:Pnma).This results in a quaternary non-centrosymmetric(NCS)RbPbPS4(space group:P212121),which possesses distinct 2D[PbPS4]−layers and Rb+occupies the interlayer spaces as the counter cations.Notably,RbPbPS4exhibits a promising overall performance,including strong deff(2.5×AgGaS2),wide IR transmittance cutoff edge(up to 18.1μm)along with the large Eg(2.75 eV),resulting in an improved laser-induced damage threshold(7.5×AgGaS2).Theoretical calculations further indicated that the favorable balance between strong deffand large Egin RbPbPS4can be attributed to the synergies of the[PbS7]and[PS4]nonlinear optical(NLO)-active units.This study not only presents a high-performance Pb-based IR-NLO candidate but also underscores the effectiveness of partial substitution of SCALP cations in inducing a CS-to-NCS structural transformation. 展开更多

Tumor-targeted delivery of nanomedicine is of great importance to improve therapeutic efficacy of cancer and minimize systemic side effects.Unfortunately,nowadays the targeting efficiency of nanomedicine toward tumor is still quite limited and far from clinical requirements.In this work,we develop an innovative peptide-based nanoparticle to realize light-triggered nitric oxide(NO)release and structural transformation for enhanced intratumoral retention and simultaneously sensitizing photodynamic therapy(PDT).The designed nanoparticle is self-assembled from a chimeric peptide monomer,TPP-RRRKLVFFK-Ce6,which contains a photosensitive moiety(chlorin e6,Ce6),aβ-sheet-forming peptide domain(Lys-Leu-Val-Phe-Phe,KLVFF),an oligoarginine domain(RRR)as NO donor and a triphenylphosphonium(TPP)moiety for targeting mitochondria.When irradiated by light,the constructed nanoparticles undergo rapid structural transformation from nanosphere to nanorod,enabling to achieve a significantly higher intratumoral accumulation by 3.26 times compared to that without light irradiation.More importantly,the conversion of generated NO and reactive oxygen species(ROS)in a light-responsive way to peroxynitrite anions(ONOO)with higher cytotoxicity enables NO to sensitize PDT in cancer treatment.Both in vitro and in vivo studies demonstrate that NO sensitized PDT based on the well-designed transformable nanoparticles enables to eradicate tumors efficiently.The light-triggered transformable nanoplatform developed in this work provides a new strategy for enhanced intratumoral retention and improved therapeutic outcome. 展开更多

As novel Zintl phases with the LiGaGe structure type,Ca1−xCexAg1−ySb has shown decent thermoelectric performance as well as complex structure transitions,which are closely related to the Ag defects in the anionic layers.In this report,La/Sr co-doped materials,Ca1−x−δSrδLaxAg1−ySb(0≤δ≤0.7),were prepared and studied regarding relevant thermoelectric properties.Interestingly,the incorporation of alkaline-earth metal Sr suggested a different structure transition mechanism from the LiGaGe type to the ZrBeSi-type,which seemed closely related to the Sr doping concentrations.Besides,significant enhancement of the thermoelectric performance resulted.For materials with a specific composition of Ca0.55Sr0.3La0.15Ag0.89Sb,a maximum zT of 0.7 has been achieved at 823 K,which also corresponded to a high average zT value of 0.66 between 774 and 1068 K. 展开更多

After the end of the cold war, the Asia-Pacific security structure has experienced great changes, especially on the occasion of the current "power-sharing" and "power-shifting" between China and the United States in the Asia-Pacific region, the Asia-Pacific security structure adjustment is especially significant. On the one hand, the Alliance structure with the United States as the pivot has experienced transformation from a hub-spokes system to a network, has formed the hierarchical layout of new alliance, quasi-alliance and potential alliance, On the other hand, emerging economies represented by China and Russia, while reinforcing the existing coordinate security framework, reshape the Asia-Pacific and even the whole Eurasia geopolitical posture through strategic initiatives such as the Belt and Road Initiative, the Eurasian Economic Union. As the third force in the Asia-Pacific security architecture, the Association of South-East Asian Nations(ASEAN) with the construction of a series of multilateral security mechanisms provides dialogue platform for the two security architectures led by major countries, and has also become one of the feasible paths to realize the future holistic security architecture in the Asia-Pacific region. Meanwhile, the major countries strategic competitions have intensified, which has gradually eroded the ASEAN ‘s cohesion, neutrality and even the central position in a holistic security architecture. The future's reconstruction of the Asia-Pacific security architecture needs to find new strategic consensus and reconfirm the ASEAN central position. 展开更多

The synthesized molecular clusters featuring the cubic[4Fe–4S]core have been studied for several decades,as they serve as true analogs of the active components in ferritin within biological systems.Such a model cluster has been extensively investigated in various fields,including structural modulation,catalysis,and self-assembly under laboratory conditions,with the aim of gaining an in-depth understanding of their roles in biological functions.Herein,we revisited three well-known[Fe4S4(SR)4]2–molecules,namely[Me4N]2[Fe4S4(SR)4](R=o-MBT,m-MBT,p-MBT),and successfully established their single crystal structures that remain unknown prior to this work.Interestingly,it is revealed that the position of the substituent methyl group has an obvious steric effect on the arrangement of the ligand around the[4Fe–4S]core,which further influences their overall packing patterns in single crystals.In addition,this work unveils two new structure transformation behaviors for the[Fe4S4(SR)4]2–system:i)the monomeric[Fe(SR)4]2–and tetrameric[Fe4S4(SR)4]2–can be interconverted,and ii)[Fe4S4(SR)4]2–can be transferred into an intriguing iron-oxide complex Na2Fe6O(OMe)18·6MeOH in a well-controlled oxidizing environment. 展开更多

Occupational structural transformation is a common pattern during the steady growth of GDP per capita in major economies worldwide.In recent years,there has been a decline in the employment share of goods occupation and an increase in service occupation within the Chinese manufacturing industry,presenting a trend of occupational structural transformation and rapid development of service-oriented manufacturing.It is an important driving force and typical performance of the high-end,intelligent,and green development of the manufacturing industry.As a strategic general technology which leads the new round of technological revolution and industrial transformation,artificial intelligence(AI)has become a new fundamental force to accelerate the occupational structural transformation and service-oriented manufacturing development in China.Thus,this paper establishes a dynamic general equilibrium model with AI technology and occupational heterogeneity,showing the endogenous mechanism of occupational structural transformation.We find that when AI technology is biased towards goods occupation,and the elasticity of substitution between goods occupation and service occupation is less than 1,then AI will drive the transformation of occupational structure from goods to service within the manufacturing sector,increase the proportion of service-oriented manufacturing,improve labor productivity of manufacturing relative to service and stabilize the real output share of manufacturing.Promoting deeper integration of different occupations,intensifying R&D in AI technology and reducing labor mobility barriers between occupations can effectively accelerate the occupational structural transformation and industrial structural upgrading.We use theoretical analysis and numerical simulation method to show the theoretical mechanism by which AI affects occupational structural transformation and industrial structural transformation from a macroeconomic perspective,and put forward policy implications on how to promote the service-oriented manufacturing development and accelerate the construction of modern industrial system through AI innovation. 展开更多

This study examines the influence of microfinance institutions’(MFIs)financial innovation on structural transformation.For this purpose,we considered a household survey from Nepal.The survey collected data on various individual and household characteristics,borrowing patterns,and occupations over the years.The key question focused on occupations before and after borrowing,a categorical response variable indicating 1 for occupational change after borrowing and 0 otherwise.Therefore,we use logistic regression to estimate the probability of occupational change,given two measures of financial innovation:loan purpose and size.The results show that the number of households involved in agriculture significantly decreased,with the majority switching to businesses and convenience stores,indicating a shift to the manufacturing and service sectors.These findings suggest that MFIs contribute to local-level structural transformation by enabling borrowers to move away from traditional employment.This study has important implications for policymakers,development practitioners,and academics interested in promoting economic development through microfinancing in low-income countries. 展开更多

Achieving the second-order nonlinear optical(NLO)effect necessitates a non-centrosymmetric(NCS)structure,which is a prerequisite,but obtaining it effectively remains greatly challenging.In pursuit of this,a strategy known as“dimensionality elevation”has been operated to create a high-dimensional NCS framework based on a low-dimensional centrosymmetric(CS)structure.Concretely,the acentric[CdS4]tetrahedral unit serves as a linkage point in the zerodimensional(0D)[Si4S10]T2-supertetrahedra,leading to the formation of the 3D NCS rigid sulfide,Cs2CdSi4S10(1),which exhibits moderate second-harmonic generation(SHG)effect(0.5×AgGaS2@1.91μm).To enhance the SHG coefficient,a structural modification has been made by replacing the Si-based framework with a Ga-based one and re-employing the“dimensionality elevation”strategy.This alteration prompted the tetrahedral[CdS4]units to connect with 0D T2-supertetrahedral[Ga4S10]motifs,creating the 3D NCS salt-inclusion chalcogenide[Ba4Cl2][CdGa4S10](2).Notably,compared with 1,compound 2 not only demonstrates an increased SHG response(1.3×AgGaS2@1.91μm)but also retains a broad band gap(3.74 eV for 1 and 3.50 eV for 2)for exceptional laser-induced damage thresholds(LIDTs,9.3×and 7.3×AgGaS2@1.06μm for 1 and 2,respectively),suggesting that compound 2 is an advanced infrared NLO material.This research pioneers new pathways for discovering NCS NLO materials through the“dimensionality elevation”strategy. 展开更多

By comparing the growth trajectories of East Asia and Latin America,this study finds that during industrialization,East Asian economies actively advanced their manufacturing sectors toward high-end production and achieved a higher relative density of high-skilled labor within this sector.In contrast,Latin American economies experienced a“low-end lock-in”in manufacturing,with high-skilled labor more heavily concentrated in the service sector.To provide a unified explanation of these patterns of industrial transformation and labor allocation,this paper develops a three-sector general equilibrium model that includes basic manufacturing(BM),high-end manufacturing(HM),and services,and incorporates labor heterogeneity.The model captures how,under different development thresholds for HM,the allocation of high-skilled labor across sectors leads to two distinct structural transformation paths:from BM to HM,or from BM to services.These paths,in turn,generate different trajectories of human capital accumulation and economic growth performance.Simulation analysis shows that dynamically adjusted industrial policies are more effective than static ones,and that combining education policy with industrial policy yields better outcomes than either policy alone.This study extends theoretical research on industrial structural transformation,highlights the importance of HM for latecomer economies,and offers theoretical underpinnings and decision-making insights for advancing new industrialization and deepening integration between industrial and talent chains. 展开更多
