AbstractQuasi‐solid aqueous zinc ion batteries (AZIBs) based on flexible hydrogel electrolytes are promising substitutions of lithium‐ion batteries owing to their intrinsic safety, low cost, eco‐friendliness and wearability. However, it remains a challenge to lower the freezing point without sacrificing the fundamental advantages of hydrogel electrolytes such as conductivity and mechanical properties. Herein, an all‐around hydrogel electrolyte is constructed through a convenient energy dissipation strategy via the rapid and reversible intramolecular/intermolecular ligand exchanges between Zn2+ and alterdentate ligands. The as‐obtained hydrogel exhibits excellent mechanical properties, fatigue resistance, high Zn‐ion conductivity (38.2 mS cm−1), good adhesion (19.1 kPa), and ultra‐low freezing point (−97 °C). Due to the alterdentate ligands help to improve the zinc ion solvation structure and guide uniform Zn deposition, the Zn||Zn symmetric cells show stable plating/stripping behavior and long‐term cycle stability. The Zn||V2O5 full cells exhibit large capacity of 230.6 mAh g−1 and high capacity retention of 75.2% after 1000 cycles. Furthermore, flexible AZIBs operate stably even under extreme conditions including low temperature (−40 °C) and large bending angle (180°). The mechanically damage‐resistant hydrogel can also be utilized in flexible strain sensors. This work offers a facile strategy for developing mechanically deformation‐resistant, dendrite‐free, and environmentally adaptable AZIBs.

AbstractThe recent discoveries of surprisingly large anomalous Hall effect (AHE) in antiferromagnets have attracted much attention due to their promising use in spintronics devices. However, such AHE‐hosting antiferromagnetic materials are rare in nature. Herein, it is demonstrated that Mn2.4Ga, a Fermi‐level‐tuned kagome antiferromagnet, has a large anomalous Hall conductivity of ≈150 Ω−1 cm−1 at room temperature that surpasses the usual high values (i.e., 20–50 Ω−1 cm−1) observed so far in two outstanding kagome antiferromagnets, Mn3Sn and Mn3Ge. Although the triangular spin structure of Mn2.4Ga shows a weak net magnetic moment of ≈0.05 µB per formula unit, it guarantees a nonzero Berry curvature in the kagome plane. Moreover, the anomalous Hall conductivity exhibits a sign reversal with the rotation of a small magnetic field that can be ascribed to the field‐controlled chirality of the spin triangular structure. This theoretical calculations further suggest that the large AHE in Mn2.4Ga originates from a significantly enhanced Berry curvature associated with the tuning of the Fermi level close to the Weyl points. These properties, together with the ability to manipulate moment orientations using a moderate external magnetic field, make Mn2.4Ga extremely exciting for future antiferromagnetic spintronics.

Published: February 2024

AbstractRecently, magnetically actuated micro/nanorobots hold extensive promises in biomedical applications due to their advantages of noninvasiveness, fuel‐free operation, and programmable nature. While effectively promised in various fields such as targeted delivery, most past investigations are mainly displayed in magnetic control of individual micro/nanorobots. Facing practical medical use, the micro/nanorobots are required for the development of swarm control in a closed‐loop control manner. This review outlines the recent developments in magnetic micro/nanorobot swarms, including their actuating fundamentals, designs, controls, and biomedical applications. The fundamental principles and interactions involved in the formation of magnetic micro/nanorobot swarms are discussed first. The recent advances in the design of artificial and biohybrid micro/nanorobot swarms, along with the control devices and methods used for swarm manipulation, are presented. Furthermore, biomedical applications that have the potential to achieve clinical application are introduced, such as imaging‐guided therapy, targeted delivery, embolization, and biofilm eradication. By addressing the potential challenges discussed toward the end of this review, magnetic micro/nanorobot swarms hold promise for clinical treatments in the future.

AbstractPhotocatalytic hydrogen peroxide (H2O2) synthesis from water and O2 is an economical, eco‐friendly, and sustainable route for H2O2 production. However, single‐component photocatalysts are subjected to limited light‐harvesting range, fast carrier recombination, and weak redox power. To promote photogenerated carrier separation and enhance redox abilities, an organic/inorganic S‐scheme photocatalyst is fabricated by in situ growing In2S3 nanosheets on a covalent organic framwork (COF) substrate for efficient H2O2 production in pure water. Interestingly, compared to unitary COF and In2S3, the COF/In2S3 S‐scheme photocatalysts exhibit significantly larger light‐harvesting range and stronger visible‐light absorption. Partial density of state calculation, X‐ray photoelectron spectroscopy, and femtosecond transient absorption spectroscopy reveal that the coordination between In2S3 and COF induces the formation of mid‐gap hybrid energy levels, leading to smaller energy gaps and broadened absorption. Combining electron spin resonance spectroscopy, radical‐trapping experiments, and isotope labeling experiments, three pathways for H2O2 formation are identified. Benefited from expanded light‐absorption range, enhanced carrier separation, strong redox power, and multichannel H2O2 formation, the optimal composite shows an impressive H2O2‐production rate of 5713.2 µmol g−1 h−1 in pure water. This work exemplifies an effective strategy to ameliorate COF‐based photocatalysts by building S‐scheme heterojunctions and provides molecular‐level insights into their impact on energy level modulation.
Spin Coupling in the Initial Stages of the Zinc‐Blende MnN Growth on the CrN (111) Surface

Published: February 2024

AbstractSpin‐polarized first‐principles calculations are carried out to study the structural, electronic, and magnetic properties of the MnN growth on the CrN (111) surface. Different magnetic configurations between Mn‐deposited atoms and the substrate are considered. The H3 site is the most favorable site for the adoption and incorporation cases and the Mn spins switch from paramagnetic to antiferromagnetic arrangement. The minimum energy pathway for the Mn diffusion is calculated, showing magnetic modifications in the substrate. A structural transition from tetragonal rock‐salt to zinc‐blende (ZB) structure as the number of MnN deposited layers increases is noticed. Thermodynamic analysis demonstrates that the growth of MnN on CrN is feasible. The density of states for an MnN layer with an extra nitrogen layer shows a half‐metallic behavior and the remaining structures exhibit a metallic character. The ZB‐MnN structures have an antiferromagnetic behavior with a metallic character. Magnetic anisotropy energies reveal a switching of easy magnetization axis, from in‐plane to out‐of‐plane with the formation of MnN on the surface. These results suggest that the CrN/ZB‐MnN system may be employed in antiferromagnetic spintronics applications as the fabrication of perpendicular magnetic tunnel junctions.

AbstractAchieving energy densities exceeding 350 Wh kg−1 while operating at elevated voltages (>4.5 V vs Li/Li+) is attainable through judicious selection of electrochemical pairs at the cathode and anode. However, current state‐of‐the‐art electrolytes exhibit limited stability when exposed to systems operating at or above 4.3 V. This limitation contributes to the degradation of electrode materials and raises critical safety concerns, impeding the commercialization of such systems. Consequently, there has been a notable surge in research efforts aimed at developing innovative electrolyte compositions capable of supporting high‐voltage lithium‐ion batteries (LIBs). A substantial portion of this research has focused on the family of organosulfur molecules, which possess high oxidative stability. Organosulfur salts also facilitate the formation of dense, ionically conductive solid electrolyte interfaces (SEI) and demonstrate excellent solubility. This article provides a comprehensive overview of the field of organosulfur electrolyte components for their applications in energy storage, encompassing solvents, alternative conducting salts, and additives. It emphasizes the idea that the deliberate design of electrolyte compositions is instrumental in controlling electrode passivation, with organosulfur‐based structures historically proving advantageous in every aspect of the electrolyte. Crucially, it should be noted that many of these components are commercially available, holding significant implications for industrial applications.

AbstractEnormous efforts are invested in developing multi‐energy harvesting technology with simple configuration and high conversion efficiency, and light‐assisted nanogenerators are considered a promising solution. Multifunctional perovskites are explored for this light‐assisted nanogenerator, owing to its powerful platform characteristics for integrating multiple energy conversion mechanisms and multi‐effects coupling phenomenon. Therefore, with the rapid progress of this emerging field, a timely and comprehensive review of this light‐assisted nanogenerator is urgently needed for updating the fundamental understanding of coupling mechanism and material‐device‐performance relationship. In this review, recent advancements of the perovskite light‐assisted nanogenerator with their advanced designs are presented. First, the fundamental properties co‐existing in perovskites are briefly introduced, as well as some emerging effects (e.g., flexoelectric). Subsequently, the further coupling mechanism between photovoltaic effect and other energy conversion effects in different light‐assisted nanogenerator are discussed in categories. And the output characteristics and potential application of various coupled devices are systematically described from the perspective of perovskites selection and device engineering. Finally, some perspectives on existing challenges and further development for light‐assisted nanogenerator are put forward, with the aim to provide useful guidance for the design of advanced devices.

AbstractObjectivesDental anthropological investigations into sexual dimorphism have conventionally concentrated on evaluating the dimensions and configuration of the enamel cap of canines. However, the morphology of the crown dentine surface can be closely linked to that of the enamel surface. This link can facilitate examination of crown morphology even when the enamel surface is slightly worn. Here, we determine if the morphology of the enamel‐dentine junction (EDJ) differs within (maxillary vs. mandibular) and between a sample of male (n = 26) and female (n = 21) contemporary human permanent canines from Europe.MethodsThe morphological data of the EDJ were gathered employing a template comprising 96 landmarks and sliding semilandmarks. Subsequently, the data underwent analysis through form space principal component analysis following Procrustes registration, utilizing standard 3D geometric morphometric techniques.ResultsSignificant differences in the morphology of the EDJ were observed between the sexes, particularly concerning the overall shape of the crown, the symmetry of the mesial and distal edges, and the development of the distal accessory ridge.ConclusionsSex differences in the morphology of the EDJ could relate in part to retention of the canine‐premolar honing complex in males. Our results indicate that analyses of the permanent canine EDJ may potentially provide a novel method for estimating the sex of adult and nonadult skeletons.

AbstractSinglet fission (SF) holds great promise for current photovoltaic technologies, where tetracenes, with their relatively high triplet energies, play a major role for application in silicon‐based solar cells. However, the SF efficiencies in tetracene dimers are low due to the unfavorable energetics of their singlet and triplet energy levels. In the solid state, tetracene exhibits high yields of triplet formation through SF, raising great interest about the underlying mechanisms. To address this discrepancy, we designed and prepared a novel molecular system based on a hexaphenylbenzene core decorated with 2 to 6 tetracene chromophores. The spatial arrangement of tetracene units, induced by steric hindrance in the central part, dictates through‐space coupling, making it a relevant model for solid‐state chromophore organization. We then revealed a remarkable increase in SF quantum yield with the number of tetracenes, reaching quantitative (196 %) triplet pair formation in hexamer. We observed a short‐lived correlated triplet pair and limited magnetic effects, indicating ineffective triplet dissociation in these through‐space coupled systems. These findings emphasize the crucial role of the number of chromophores involved and the interchromophore arrangement for the SF efficiency. The insights gained from this study will aid designing more efficient and technology‐compatible SF systems for applications in photovoltaics.

Acylated N‐acetyl hexosamine hemiacetals are known for their cytotoxicity. We have previously reported that cytotoxicity can be increased by replacing one or more acyloxy groups with fluorine. Herein, we present the synthesis of 4,6‐difluorinated d‐gluco‐ and 4‐fluorinated d‐galacto‐configured hexosamine‐derived glycoconjugates with organoruthenium or ferrocene complexes and their in vitro cytotoxicity against three cancer cell lines (A2780, SK‐OV‐3, and MDA‐MB‐231) and one noncancerous cell line (HEK‐293). The attachment of the organometallic moiety at the 2‐position significantly enhanced the cytotoxicity, especially against triple‐negative MDA‐MB‐231 and the cisplatin resistant SK‐OV‐3 cancer cells. We observed a clear significance of an unprotected and acetyl protected anomeric hydroxyl for the cytotoxicity. Glycoconjugates with a non‐hydrolysable organic or organometallic group at the anomeric position were generally nontoxic. A more detailed analysis revealed that, in particular, complexes with the ruthenium tetrazene complex induced apoptosis in both SK‐OV‐3 and MDA‐MB‐231 cells, as demonstrated by western blot analysis and Annexin V‐FITC/PI staining. The structures of the two most cytotoxic organoruthenium and ferrocene glycoconjugates were confirmed by X‐ray diffraction analysis.

AbstractIn the present study, solid polymer electrolytes (SPEs) based on poly (vinyl alcohol) (PVA) doped with lithium bromide (LiBr) were prepared by solution casting method. Fourier transform infrared spectroscopy results affirm the complexation of LiBr with PVA. X‐ray diffraction results exhibit the increase of amorphous nature of the polymer electrolytes, which is also observed in scanning electron microscopy images and atomic force microscopy topographs. Thermogravimetric analysis thermographs endorse the increase of thermal stability of the polymer due to doping. Dielectric studies exhibit non‐Debye nature of the polymer electrolytes. Conductivity spectra reveal the maximum ionic conductivity (1.15 × 10−4 S/cm) for 20 wt% LiBr/PVA electrolyte at ambient temperature. Impedance analysis reveals the decrease of ionic relaxation in the polymer electrolytes and the studied transport properties of the electrolyte show that the major contribution to the conduction in this polymer electrolyte is ions.

AbstractGeopolymers (GPs) are emerging, low‐density ceramic materials that are simple to manufacture, with high elastic modulus and strength, albeit with low toughness. Fiber reinforcements have been used to achieve varied ductile behaviors, but little is known about the GP addition to polymeric frame structures. Thus, drawing inspiration from the nanostructure of bones, this paper investigated an interpenetrating, co‐continuous composite consisting of a GP as the stiff but brittle phase, and a 3D‐printed polymer (PA12 White) as the soft and deformable phase. The composite mechanical properties and failure modes were studied experimentally using uniaxial compression and four‐point bending tests. The co‐continuous network constrained brittle cracking within the GP and reduced strain localization in the polymer. The results showed that the composite had higher strength (56.11 ± 2.12 MPa) and elastic modulus (6.08 ± 1.37 GPa) than the 3D‐printed polymer and had higher toughness (5.98 ± 0.24 MJ/mm3) than the GP for the specific geometries examined. The shape effect study demonstrated that cubic structures had higher elastic modulus and strength but at the expense of lower toughness when compared to rectangular prism structures. The study of scale effects indicated that increasing the number of periodic unit cells while maintaining consistent bulk dimensions led to augmented strength and toughness, albeit without statistically significant alterations in elastic modulus. Thus, this paper presents an experimental realization of a novel, bio‐inspired, interpenetrating, GP–polymer composite design, offering improved strength and toughness. It also provides valuable insights into the shape and size effects on the mechanical properties of this new composite.

AbstractThe predatory stink bug Arma custos has been selected as an effective biological control agent and has been successfully massly bred and released into fields for the control of a diverse insect pests. As a zoophytophagous generalist, A. custos relies on a complex neuropeptide signaling system to prey on distinct food and adapt to different environments. However, information about neuropeptide signaling genes in A. custos has not been reported to date. In the present study, a total of 57 neuropeptide precursor transcripts and 41 potential neuropeptide G protein‐coupled receptor (GPCR) transcripts were found mainly using our sequenced transcriptome data. Furthermore, a number of neuropeptides and their GPCR receptors that were enriched in guts and salivary glands of A. custos were identified, which might play critical roles in feeding and digestion. Our study provides basic information for an in‐depth understanding of biological and ecological characteristics of the predatory bug and would aid in the development of better pest management strategies based on the effective utilization and protection of beneficial natural enemies.
Analysis of human epidermal growth factor receptor 2 interaction on aptamer‐probed interdigitated electrode for breast cancer diagnosis
Authors: Hao Yingxin , Gopinath Subash C. B. 
Published: February 2024

AbstractBreast cancer has been reported to be high in its incidence with women, and early identification of breast cancer helps to improve and provide an effective treatment. Tumor markers are active substances; in particular, human epidermal growth factor receptor 2 (HER2) is over‐expressed at the level of 20%–30%. This research work developed a highly sensitive HER2 biosensor on the interdigitated electrode (IDE) by using aptamer as a detection probe. To enhance the analytical performances, aptamer was attached to the gold nanoparticle and immobilized on the IDE through a chemical linker [(3‐aminopropyl)triethoxysilane]. On the aptamer conjugation, HER2 was quantified through current‐volt measurements, and the limit of detection of HER2 was calculated as 1 pg/mL on a linear range from 0.1 to 3000 pg/mL at anR2(regression coefficient) of 0.9657. Further, a selective performance with human serum increased the current responses by increasing HER2 concentrations. Specific experiments with control protein and complementary aptamer sequence failed to enhance the current responses. This HER2 biosensor reflects the occurrence of breast cancer at its lower abundance and helps to identify the associated complications.
