Published: September 2024

AbstractDie DNA taugt zu mehr als nur zur α‐Helix – auf bestimmte Weise manipulierte DNA faltet sich zum Beispiel zu Platten. Darauf platziert die Gruppe von FCI‐Dozentenpreisträgerin Amelie Heuer‐Jungemann nanometergenau Proteine und lässt sie interagieren. Als Wirkstoffträger eignen sich die Platten bisher nicht, da sie im Menschen sofort zerfallen. Aber auch da hat die Gruppe eine Idee.

AbstractBACKGROUNDThe citri red mite, Panonychus citri (McGregor), is an important citrus pest worldwide, causing enormous economic losses to citrus production. Bifenazate is a widely used acaricide for controlling P. citri. The detoxification mechanism of bifenazate is not clear in P. citri.RESULTSPcGSTMu2, a significantly upregulated GST gene, was identified by the transcriptome analysis of P. citri after bifenazate exposure. The expression level of PcGSTMu2 was significantly increased after bifenazate exposure. By using RNAi of PcGSTMu2, the susceptibility of P. citri to bifenazate was significantly increased. Protein modeling and docking of PcGSTMu2 with GSH and bifenazate indicated the potential amino acid residues for binding in the active site. Heterologous expression and in vitro functional assays further revealed that PcGSTMu2 could deplete bifenazate.CONCLUSIONThese results indicated that PcGSTMu2 plays an important role in the detoxification of bifenazate in P. citri and provides the molecular foundation for understanding bifenazate metabolism in P. citri. © 2024 Society of Chemical Industry.

Published: September 2024

AbstractBACKGROUNDThe development of fungicides with low cross resistance, high efficacy and low resistance plays a central role in protecting crops, reducing yield losses, improving quality and maintaining global food security. Based on this important role, after a systematic optimization strategy, novel heterocyclic amide derivatives bearing diphenylmethyl fragment were screened, synthesized and verified with the spectrographic and x‐ray diffraction analysis.RESULTSIn this study, the aforementioned optimization obtained compound B19 that was measured for antifungal activity against Rhizoctonia solani (median effective concentration, EC50 = 1.11 μg mL−1). Meanwhile, the anti‐R. solani protective effect (79.34%) of compound B19 was evaluated in vivo at 100 μg mL−1, which is comparable to that of the control agent fluxapyroxad (80.67%). Thence, morphological observations revealed that compound B19 induced mycelium disruption and shrinking, mitochondrial number reduction and apoptosis acceleration, consistent with the results of the mitochondrial membrane potential and cell membrane permeability. Further investigations found that the potential target enzyme of compound B19 was SDH, which exerted fluorescence quenching dynamic curves similar to that of the commercialized SDHI fluxapyroxad. Additionally, research by molecular docking and MD simulations demonstrated that compound B19 had a similar binding mode acting on the surrounding residues in the SDH active pocket to that offluxapyroxad.CONCLUSIONThe above results demonstrated that heterocyclic amide derivatives containing a diphenylmethyl moiety are promising scaffolds for targeting SDH of fungi and provide valuable antifungal leads with the potential to develop new SDH inhibitors. © 2024 Society of Chemical Industry.
Migration intentions in a politically divided context: The interactive roles of affective polarization and dyadic political attitudes
Authors: Cheung Adam Ka‐Lok , Lui Lake 
Published: September 2024

AbstractThis study examines migration intentions in a politically divided context, focusing on the interactive roles of individuals’ and the spouses’ affective polarization and political attitudes. Our study uses Hong Kong as a case study to elucidate migration intentions in the context of political polarization and increasing authoritarianism. We investigate how individuals facing the same political conditions exhibit varying inclinations to migrate. Our analysis is based on dyadic data from a representative household survey involving 1003 married couples. The findings reveal that spousal pro‐democratic attitudes and affective polarization are associated with stronger migration intentions, with significant implications for predicting migration patterns. Moreover, the study highlights the significance of the interactive role between individuals’ and the spouses’ political attitudes in shaping migration intentions. These findings contribute to a deeper understanding of the complex interplay between dyadic political attitudes, affective polarization, and migration intentions in highly developed societies with advanced economies.
Homelessness and migration: The geography of homeless migrants in China
Authors: Gong Yue , Xu Yifang , Xie Bo , MacLachlan Ian , Chen Yujie 
Published: September 2024

AbstractHomeless people have become more visible in China in recent years. However, research on Chinese homelessness in general and homeless migrants in particular is still very limited. Based on the China Migrants Dynamic Survey, this pioneering exploration of the geography of homeless migrants in China arrives at three conclusions. First, although homeless migrants are often scorned as an underclass of derelict drifters, the majority are educated, married, and employed, sometimes temporarily. Second, although most homeless migrants congregate in the most developed coastal regions, the number of homeless migrants as a proportion of total migrants is relatively high in some remote provinces, with significant numbers residing in rural areas. Third, in addition to the three established drivers: the housing market, economic opportunity, and social support, prejudice towards the homeless is shown to be an important factor in the concentration of homeless migrants and their exclusion from urban society. This paper contributes to an understanding of homeless migrants in China and the factors accounting for their spatial distribution.
A system reliability demonstration test design method based on subsystem test data
Authors: Zhang Dian , Jiang Ping , Xing Yunyan 
Published: September 2024

AbstractReliability demonstration test (RDT) is the test to verify that the reliability of the product meets the reliability requirements during product development and is usually required to be performed to determine whether it can be accepted. It is essential for complex systems with higher costs. However, the traditional test plans such as the plan in the current RDT standard GJB‐899A have the problem of too long test time or too high risk. In addition, the test data of the complex system itself is usually less, but the test data of the subsystem is easier to obtain. In this paper, the research object is the system, and the main research content is how to use the reliability growth data in the development stage of the subsystem to design the system RDT. First, based on the reliability growth model, the test data in the development stage of the subsystems are modeled to obtain the reliability of each subsystem. The Bayesian theory is used to obtain the lifetime distribution of the system. Then, according to the definition of the two types of risks in the RDT, the life distribution of the product is integrated into the two types of risks, and the RDT plans of the system are designed. Finally, a simulation case is used to verify our RDT design method, and the results show that compared with the traditional plan, our RDT plan designed has a shorter test time and lower test risk.

Published: September 2024

AbstractThis article tackles the complex challenge of multi‐vehicle motion planning by presenting the novel Sequential Convex Programming‐based Distributed Model Predictive Control (SCP‐DMPC) algorithm. Existing methods often struggle with the nonconvex nature of optimization in multi‐vehicle motion planning, frequently compromising on computational efficiency. SCP‐DMPC innovatively combines the predictive control of DMPC with the optimization prowess of SCP to address these issues efficiently, while adhering to both physical and operational constraints. To ensure precise attainment of target poses, a three‐stage control strategy is introduced, with theoretical analysis on its recursive feasibility and asymptotic stability, enhancing the reliability of the algorithm. Moreover, a heuristic‐based deadlock resolution scheme is devised to prevent vehicle stalling, a common issue in cooperative motion. Validated through simulations in challenging scenarios, including symmetric position swapping and obstacle‐laden formation transition, SCP‐DMPC demonstrates superior adaptability, precision, and efficiency. These results underscore its potential for robust, real‐time unmanned vehicle applications, suggesting new directions for future research and development in the field.
Tunable Electronic, Optoelectronic, and Photocatalytic Properties of MoS2 and GaS Monolayers in the MoS2/GaS Heterostructure

Published: September 2024

AbstractThe electronic structure calculations show that the GaS and MoS2 monolayer and MoS2/GaS hetero‐bilayer systems are semiconducting materials. It is also justified by the density of states. In the hetero‐bilayer system, the band gap is reduced. It causes an increase in the absorption, compared to their monolayers, of incident light in the visible region. This may be because of the charge transfer and the interlayer interaction between these monolayers in the heterostructure form. The calculated higher extinction coefficient causes the fast absorption of light, hence, the increased absorption coefficient. The heterostructure system makes the refractive index and reflection coefficient of GaS and MoS2 monolayers tuneable. The static reflection coefficient is in the following order GaS < MoS2/GaS < MoS2. It means that the MoS2/GaS heterostructure system can increase the static refractive index of GaS and decrease that of MoS2 monolayers simultaneously. The calculated band edge positions show that the MoS2 and GaS monolayers have excellent water oxidation and reduction capability, respectively. These predictions show that the proposed heterostructure may be a potential candidate for nanoelectronics and optoelectronics.

AbstractLewis acid‐catalyzed ring‐opening reactions of cyclobutanones were mostly achieved through cleavage of a single C2−C3 bond to deliver cyclic products. Herein, an unprecedented Lewis acid catalyzed synergistic cleavage of both C2−C3 bonds in 3‐arylcyclobutanones was realized under participation of water, providing a series of aryl alkyl ketones in mild conditions. A broad scope of substrates decorated with various substituents were well accommodated. Mechanistic proposal including the function of water was unambiguously validated by experimental verification.

Published: September 2024

AbstractThis work aims to detect the Mucin‐1 (MUC1) breast cancer biomarker using a label‐free impedimetric biosensor of silver molybdate anchored on reduced graphene oxide (Ag2MoO4‐rGO). A hydrothermal method has been employed to synthesize the Ag2MoO4‐rGO nanocomposite. Subsequently, they have been studied through analytical characterization techniques to study the electrocatalytic activity, electroactive surface area, surface functionalities, and morphologies to determine the suitability of the material for biosensor fabrication. Results reveal that the Ag2MoO4‐rGO nanocomposite possesses excellent electroconductivity and surface properties that have significant characteristics for the biosensor's performance. A biosensor has been fabricated by the immobilization of Ag2MoO4‐rGO nanocomposite and anti‐MUC1 antibody on a glassy carbon electrode. The electroanalytical studies revealed that the biosensor has excellent sensitivity and detection performance having a wide linearity of 100 fg mL−1–5 ng mL−1 and a low limit of detection of 2.70 fg mL−1. Moreover, the remarkable selectivity, reproducibility, stability, and detection in serum samples determine the high performance of the biosensor. Therefore, the presented biosensor could be a promising diagnostic tool that shows the remarkable potential to efficiently detect the breast cancer MUC1 biomarker in patient's serum samples.
Honeycomb Bionic Graphene Oxide Quantum Dot/Layered Double Hydroxide Composite Nanocoating Promotes Osteoporotic Bone Regeneration via Activating Mitophagy
Authors: Li Dan , Dai Danni , Wang Jianrong , Zhang Chao 
Published: September 2024

AbstractAbnormal osteogenic and remodeling microenvironment due to osteoblast apoptosis are the primary causes of delayed fracture healing in osteoporotic patients. Magnesium (Mg) alloys exhibit biodegradability and appropriate elastic moduli for bone defects in osteoporosis, but the effect on the local bone remodeling disorder is still insufficient. Inspired by the “honeycomb,” layered double hydroxide (LDH) with regular traps with graphene oxide quantum dots (GOQDs) inlayed is constructed by pulsed electrodeposition to generate GOQD/LDH composite nanocoatings on the surfaces of Mg alloy substrates. The honeycomb bionic multi‐layer stereoscopic structure shows good regulation of the degradation of Mg alloy for the support of healing time required for osteoporotic bone defect. Within its lattice, the local microenvironment conducive to osteogenesis is provided by both the rescue effect of GOQD and LDH. The osteoblast apoptosis is rescued due to the activation of mitophagy to clear dysfunctional mitochondria, where the upregulation of BNIP3 phosphorylation played a key role. The osteoporotic rat model of femoral defects confirmed the improvement of bone regeneration and osseointegration of GOQD/LDH coating. In summary, honeycomb bionic composite nanocoatings with controllable degradation and excellent pro‐osteogenic performance demonstrated a promising design strategy on Mg alloy implants in the therapy of osteoporotic bone defects.

AbstractTailoring the optoelectronic characteristics of colloidal quantum dots (QDs) by constructing a core/shell structure offers the potential to achieve high‐performing solution‐processed photoelectric conversion and information processing applications. In this work, the direct growth of wurtzite ternary AgInS2 (AIS) shell on eco‐friendly AgGaS2 (AGS) core QDs is realized, giving rise to broadened visible light absorption, prolonged exciton lifetime and enhanced photoluminescence quantum yield (PLQY). Ultrafast transient absorption spectroscopy demonstrats that the photoinduced carrier separation and transfer kinetics of AGS QDs are significantly optimized following the AIS shell coating. As‐synthesized environmentally benign AGS/AIS core/shell QDs are employed to fabricate photodetectors (PDs), showing a remarkable responsivity of 38.4 A W−1 and a detectivity of 2.4 × 1012 Jones under visible light illumination (405 nm). Moreover, the fabricated QDs‐PDs exhibit superior image‐sensing capability to record complex patterns with high resolution (160 × 160 pixels) under visible light illumination at 405 and 532 nm. The findings indicate that the direct growth of multinary narrow‐band shell materials on eco‐friendly QDs holds great promise to implement future “green”, cost‐effective and high‐performance optoelectronic sensing/imaging systems.

Published: September 2024

AbstractAqueous zinc‐ion batteries (AZIBs) stand out among new energy storage devices due to their excellent safety and environmental friendliness. However, the formation of dendrites and side reactions on the zinc metal anode during cycling have become the major obstacles to their commercialization. This study innovatively selected Sodium 4‐vinylbenzenesulfonate (VBS) as a multifunctional electrolyte additive to address the issues. The dissociated VBS‐ anions can not only significantly alter the hydrogen bond network structure of H2O in the electrolyte, but also preferentially adsorb on the surface of the zinc anode before H2O molecules, which will result in the development of organic anion‐rich interface and alterations to the electrical double layer (EDL) structure. Furthermore, the ─C═C─ structure in VBS leads to the formation of an in situ polymerized organic anion solid electrolyte interface (SEI) layer that adheres to the surface of the zinc anode. The mechanisms work together to significantly improve the performance of Zn//Zn symmetric batteries, achieving a cycle life of over 1800 h at 1 mA cm−2 and 1 mAh cm−2. The introduction of VBS also enhances the cycling performance and capacity of Zn//δ‐MnO2 full cells. This study provides a low‐cost solution for the development of AZIBs.

Authors: Li Chao‐Qun , Wang Jian‐Jun 
Published: September 2024

AbstractCopper sulfides (CuxS, 1 ≤ x ≤ 2) are notable for their unique photoelectric properties and potential applications, particularly in photo/electrocatalysis. These materials are valued for their tunable band gap, near‐infrared optical characteristics, and plasmonic resonance effects. However, challenges such as low catalytic activity and limited stability impede their practical applications. This review addresses these issues by exploring advanced strategies for electronic structure modulation, including atomic doping, shape alteration, heterojunction construction, and defect introduction to enhance catalytic efficiency. A detailed analysis of the optical and electrical properties of CuxS across various stoichiometric ratios and crystal structures is provided, offering a comprehensive overview of their applications in photocatalysis, electrocatalysis, and photo/electrocatalysis. Additionally, the review synthesizes current knowledge and highlights the potential of these strategies to optimize CuxS‐based photo/electrocatalysts, proposing future research directions to bridge the gap between theoretical studies and practical applications. This work underscores the importance of CuxS in photo/electrocatalysis and aims to inspire further innovation and exploration in this field, emphasizing its significance in material science and engineering.

Published: September 2024

AbstractThe stability of aqueous zinc metal anodes is still constrained by their severe dendrite growth. Optimizing electric field distribution and crystallography to modulate the diffusion and deposition behavior of zinc ions can effectively suppress dendrite growth. However, the fabrication strategy to directly endow specific textured zinc anodes with gradient electric field distribution is still lacking. Herein, a strategy combining crystal reconstruction of commercial zinc foil with graphene oxide (GO) protective layer is proposed to construct an in situ gradient electric field‐enhanced strong (002) textured GO@ZnO/Zn(002) anode. Based on the experimental and theoretical results, the GO protective layer can regulate a wide‐range homogeneous Zn2+ ions flow, while the dense and uniform ZnO/Zn(002) nanoneedles /nanoparticles can enhance localized polarized electric field to accelerate rapid localized transfer of Zn2+ ions and guide them toward directional deposition along (002) plane. Therefore, the hierarchical GO@ZnO/Zn(002) anode enables the symmetric cell to operate continuously and stably for 5700 and 4200 h at 2 and 4 mA cm−2, respectively, which is comparable to or better than most high‐end Zn anodes. This work presents new insights into the zinc foil reconstruction and gradient electric field fabrication strategy, offering a scalable approach for the development of long‐term stable metal anodes.
