AbstractSome organisms often use adhesive setae to manipulate objects or communicate critical signals for survival through subtle surface‐transmitted vibrations, along with locomotion and long‐term adherence. Inspired by this phenomenon, the spatially selective vibration‐transmitting electronics of a multi‐pixelated electroactive‐actuating adhesive patch coupled with small adhesive architectures are presented. Here, diving beetle‐like small dense hairs possessing concave cavities are introduced to obtain high adaptability on various non‐flat surfaces in dry or wet conditions. Based on the versatile vibration‐transmitting platform, the ensuing lightweight, spatially‐selective, switchable‐adhesive device is demonstrated to effectively manipulate multiple objects simultaneously, thus overcoming the limitations of existing monotonous transportation devices. In addition, the electronics can be applied to the stretchable skin‐conforming haptic interface with high breathability and repeatable attachment capability, capable of recognizing complex outward textures of virtual objects. This skin‐adaptive haptic electronics can amplify the tiny vibrotactile feedback from the diverse surface textures of virtual creatures due to its possession of bioinspired architectures at the human–machine interface. Here, the stably encapsulated device is integrated with machine learning‐based comprehension for reproducible expression. Therefore, this technology offers promise in virtual reality and augmented reality applications.

AbstractMultimaterial integration, such as soft elastic and stiff components, exhibits rich deformation and functional behaviors to meet complex needs. Integrating multimaterials in the level of individual fiber is poised to maximize the functional design capacity of smart wearable electronic textiles, but remains unfulfilled. Here, this work continuously integrates stiff and soft elastic components into single fiber to fabricate encoded mechano‐metafiber by programmable microfluidic sequence spinning (MSS). The sequences with programmable modulus feature the controllable localization of strain along metafiber length. The mechano‐metafibers feature two essential nonlinear deformation modes, which are local strain amplification and retardation. This work extends the sequence‐encoded metafiber into fiber networks to exhibit greatly enhanced strain amplification and retardation capability in cascades. Local strain engineering enables the design of highly sensitive strain sensors, stretchable fiber devices to protect brittle components and the fabrication of high‐voltage supercapacitors as well as axial electroluminescent arrays. The approach allows the scalably design of multimaterial metafibers with programmable localized mechanical properties for woven metamaterials, smart textiles, and wearable electronics.

AbstractNanoarray electrocatalysts with unique advantage of facilitating gas bubble detachment have garnered significant interest in gas evolution reactions (GERs). Existing research is largely based on a static hypothesis, assuming that buoyancy is the only driving force for the release of bubbles during GERs. However, this hypothesis overlooks the effect of the self‐dynamic electrolyte flow, which is induced by the release of mature bubbles and helps destabilize and release the smaller, immature bubbles nearby. Herein, the enhancing effect of self‐dynamic electrolyte flow on nanoarray structures is examined. Phase‐field simulations demonstrate that the flow field of electrode with arrayed surface focuses shear force directly onto the gas bubble for efficient detachment, due to the flow could pass through voids and channels to bypass the shielding effect. The flow field therefore has a more substantial impact on the arrayed surface than the nanoscale smooth surface in terms of reducing the critical bubble size. To validate this, superaerophobic ferrous‐nickel sulfide nanoarrays are fabricated and employed for water splitting, which display improved efficiency for GERs. This study contributes to understanding the influence of self‐dynamic electrolyte on GERs and emphasizes that it should be considered when designing and evaluating nanoarray electrocatalysts.

AbstractThin polymer coatings are used to improve the interface between biological species and functional materials. Their interaction is significantly influenced by the functional groups and roughness of the polymer film and prediction of the interaction is thus of great interest. However, for conventional polymer films, this cannot be examined independently because of the interplay of defects, residual solvent molecules, roughness, and functional groups. Solvent‐free polymer films prepared by initiated chemical vapor deposition (iCVD) exhibit conformal, defect‐free characteristics and enable precise tailoring of the functional groups. This facilitates to isolate the contribution of functional groups on the bio‐interface performance. Consequently, in silico studies can enable a prediction of ligand interaction in anti‐viral activity for SARS‐CoV‐2 based on defined polymer and key protein structures. Furthermore, the cell viability of human fibroblasts can be traced back to the functional groups of the repeating units. For human liver cancer cell culture, it turns out that more sophisticated models are needed. The insilico‐iCVD approach can enable precise tailoring of complex polymer films optimized for the respective interfaces. In addition, this first big scan of the bio‐interface performance of iCVD films enables a solid starting point in areas like anticancer, antiviral, and biocompatibility for future studies.

Published: October 2023

AbstractThe search for new ultraviolet (UV) or deep‐UV nonlinear optical (NLO) crystals would greatly prompt the development of laser science and technology. As the NLO performance of these crystals is mainly determined by the anionic groups, herein the (SO3CF3)− group is highlighted as a promising non‐π‐conjugated NLO‐active motif with excellent deep‐ultraviolet (DUV) transmission and good NLO properties. First‐principles studies reveal that this group possesses the largest HUMO‐LOMO gap among the (SO4)2−‐based units, as well as a relatively large NLO response. The further experiments demonstrate that the CsSO3CF3 compound containing the (SO3CF3)− motif exhibits th UV cutoff edge below 200 nm and an NLO effect ≈0.8× KH2PO4, confirming the potentials of this new motif for UV and DUV NLO applications.

AbstractDensity functional theory is used to compare the catalytic performance of PtPdRhFeCo(100) high entropy alloy (HEA) three‐way catalyst (TWC) to the conventional Pt(100) in the NO reduction step during NH3 production that supplies to passive NH3‐SCR. Stronger adsorption of NO on the HEA(100) surface is beneficial to capture NO. During adsorption, the catalyst surface acts as an electron donor while the adsorbate is the acceptor on both HEA(100) and Pt(100) systems. Herein, the reaction mechanism of NO reduction can be classified into two steps: 1) NO activation and 2) product formation. During NO activation, direct NO dissociation is the preferable pathway on both HEA(100) and Pt(100) surfaces with the same Ea, whereas HNO and NOH pathways on HEA(100) are suppressed. For NH3, N2, and N2O production on HEA(100) is found to be more difficult than on Pt(100). However, the thermodynamic driving force of all reactions on HEA(100) is more spontaneous than on Pt(100). Also, the rate‐determining step on HEA(100) is found to be NH3 formation different from the Pt(100), while difficult H diffusion on HEA(100) is the key factor that reduces NH3 production.

AbstractThe electronic structure of halide perovskites is central to their carrier dynamics, enabling the excellent optoelectronic performance. However, the experimentally resolved transient absorption spectra exhibit large discrepancies from the commonly computed electronic structure by density functional theory. Using pseudocubic CsPbI3 as a prototype example, here, it is unveiled with both ab initio molecular dynamics simulations and transmission electron microscopy that there exists pronounced dynamical lattice distortion in the form of disordered instantaneous octahedral tilting. Rigorous first‐principles calculations reveal that the lattice distortion substantially alters the electronic band structure through renormalizing the band dispersions and the interband transition energies. Most notably, the electron and hole effective masses increase by 65% and 88%, respectively; the transition energy between the two highest valence bands decreases by about one half, agreeing remarkably well with supercontinuum transient‐absorption measurements. This study further demonstrates how the resulting electronic structure modulates various aspects of the carrier dynamics such as carrier transport, hot‐carrier relaxation, Auger recombination, and carrier multiplication in halide perovskites. The insights provide a pathway to engineer carrier transport and relaxation via lattice distortion, enabling the promise to achieve ultrahigh‐efficiency photovoltaic devices.

AbstractIn the quest to produce artificial cells, one key challenge that remains to be solved is the recreation of a complex cellular membrane. Among the existing models, giant unilamellar vesicles (GUVs) are particularly interesting due to their intrinsic compartmentalisation ability and their resemblance in size and shape to eukaryotic cells. Many techniques have been developed to produce GUVs all having inherent advantages and disadvantages. Here, the authors show that fluorinated silica nanoparticles (FNPs) used to form Pickering emulsions in a fluorinated oil can destabilise lipid nanosystems to template the formation of GUVs. This technique enables GUV production across a broad spectrum of buffer conditions, while preventing the leakage of the encapsulated components into the oil phase. Furthermore, a simple centrifugation process is sufficient for the release of the emulsion‐trapped GUVs, bypassing the need to use emulsion‐destabilising chemicals. With fluorescent FNPs and transmission electron microscopy, the authors confirm that FNPs are efficiently removed, producing contaminant‐free GUVs. Further experiments assessing the lateral diffusion of lipids and unilamellarity of the GUVs demonstrate that they are comparable to GUVs produced via electroformation. Finally, the ability of incorporating transmembrane proteins is demonstrated, highlighting the potential of this method for the production of GUVs for artificial cell applications.

AbstractThe oxygen evolution reaction (OER) activity of transition metal (TM)‐based (oxy)hydroxide is dominated by the number and nature of surface active sites, which are generally considered to be TM atoms occupying less than half of surface sites, with most being inactive oxygen atoms. Herein, based on an in situ competing growth strategy of bimetallic ions and OH− ions, a facile one‐step method is proposed to modulate oxygen defects in NiFe‐layered double hydroxide (NiFe‐LDH)/FeOOH heterostructure, which may trigger the single lattice oxygen mechanism (sLOM). Interestingly, by only varying the addition of H2O2, one can simultaneously regulate the concentration of oxygen defects, the valence of metal sites, and the ratio of components. The proper oxygen defects promote synergy between the adsorbate evolution mechanism (AEM, metal redox chemistry) and sLOM (oxygen redox chemistry) of OER in NiFe‐based (oxy)hydroxide, practically maximizing the use of surface TM and oxygen atoms as active sites. Consequently, the optimal NiFe‐LDH/FeOOH heterostructure outperforms the reported non‐noble OER catalysts in electrocatalytic activity, with an overpotential of 177 mV to deliver a current density of 20 mA cm−2 and high stability. The novel strategy exemplifies a facile and versatile approach to designing highly active TM‐LDH‐based OER electrocatalysts for energy and environmental applications.

AbstractThe electrocatalytic conversion of nitrate (NO3‾) to NH3 (NO3RR) offers a promising alternative to the Haber–Bosch process. However, the overall kinetic rate of NO3RR is plagued by the complex proton‐assisted multiple‐electron transfer process. Herein, Ag/Co3O4/CoOOH nanowires (i‐Ag/Co3O4 NWs) tandem catalyst is designed to optimize the kinetic rate of intermediate reaction for NO3RR simultaneously. The authors proved that NO3‾ ions are reduced to NO2‾ preferentially on Ag phases and then NO2‾ to NO on Co3O4 phases. The CoOOH phases catalyze NO reduction to NH3 via NH2OH intermediate. This unique catalyst efficiently converts NO3‾ to NH3 through a triple reaction with a high Faradaic efficiency (FE) of 94.3% and a high NH3 yield rate of 253.7 μmol h−1 cm−2 in 1 M KOH and 0.1 M KNO3 solution at ‒0.25 V versus RHE. The kinetic studies demonstrate that converting NH2OH into NH3 is the rate‐determining step (RDS) with an energy barrier of 0.151 eV over i‐Ag/Co3O4 NWs. Further applying i‐Ag/Co3O4 NWs as the cathode material, a novel Zn‐nitrate battery exhibits a power density of 2.56 mW cm−2 and an FE of 91.4% for NH3 production.

Published: October 2023

AbstractThe high activity of water molecules induces notorious side reactions that seriously impair the stability of the Zn metal anode. Inspired by the mechanism of proton transfer in an aqueous solution, ectoine (ET) with a kosmotropic effect is first introduced into the typical aqueous electrolyte of aqueous zinc‐ion batteries (ZIBs). The hydrogen bond enhancement brought by the ET additive increases the energy barrier for the reconfiguration of hydrogen bonds, thereby impeding the hopping transport of protons based on the Grotthuss mechanism. The inhibited hydrogen evolution reaction (HER) by impeded proton transfer is strongly proved by in situ electrochemical gas chromatography (EC‐GC). The distinctive hydrogen bond enhancement effect of ET results in remarkably improved Zn anode stability while maintaining fast reaction kinetics. Consequently, the Zn//Zn symmetric cell delivers an ultra‐long cycle life of 5700 h 1 mA cm−2/1 mAh cm−2 and 2000 h at 5 mA cm−2/5 mAh cm−2 with lower voltage hysteresis, extending a cycling life by >27 and 24 times without sacrificing reaction kinetics.

AbstractWe examined whether folate‐fortified maize (FFM) improves the health of rural women of childbearing age and whether the health intervention is associated with the consumer willingness‐to‐pay (WTP) for FFM. First, a randomized single‐blind FFM intervention trial was conducted in rural childbearing‐aged women. Participants (n = 55) consumed one stalk of either FFM (treatment group) or ordinary maize (control group) daily. This dietary intervention lasted for 2 months, during which we assessed the participants' serum folate levels at baseline, mid stage (after 1 month), and final stage (after 2 months) to evaluate the health effect of FFM. We found that the serum folate level in the treatment group (13.31 ng/mL) was 3.40 ng/mL higher than that in the control group (9.91 ng/mL) in the final stage of the study. These findings suggest that regular dietary FFM intake significantly increased serum folate levels in rural Chinese women. Second, we further expanded our study by involving 181 local rural women with similar demographic characteristics to participate in a Becker–DeGroot–Marschak (BDM) bidding experiment to measure their WTPs for FFM. Results showed that local consumers were willing to pay 2.82 Chinese Yuan (CNY) per stalk of FFM, approximately 1.21 CNY higher than the price of ordinary maize. And women who participated in and completed the intervention trial had a higher preference for FFM during the evaluation. We provide evidence on the health improvement effect of biofortified foods and shed light on the associated consumer valuation and policy implementation.

AbstractObjectivesThis study aimed at evaluating the agreement between bioelectrical impedance analysis (BIA) using ABC‐02 Medas and A‐mode ultrasound (AUS) using BodyMetrix™ BX2000 for fat mass (FM), fat free mass (FFM), and body fat percentage (%BF) in females.MethodsThe cross‐sectional, single‐center, observational study was performed in 206 female subjects aged 18–67 years. The examination program included measurements of body height and weight along with waist, hip circumferences, and body composition analysis. The measurements were performed by ultrasound scanner and bioimpedance analyzer.ResultsWe found that 20.9% of women were obese based on BMI (≥30 kg/m2), which was significantly lower when using a criterion based on body fat percentage (%BF ≥ 30%) measured with US (53.4%, p = .0056) or BIA (54.8%, p = .0051). At the group level, both methods were found interchangeable and showed practically negligible differences (0.1% for %BF, 0.5 kg for FM, and 0.4 kg for FFM). Agreement analysis conducted in the whole sample revealed a low level of agreement in estimating %BF (CCC = 0.72 0.77 0.82) and FFM (CCC = 0.81 0.84 0.86), and medium level of agreement in estimating FM (CCC = 0.91 0.93 0.94). The level of agreement in estimating %BF and FFM was improved to the medium level with the use of newly generated prediction equations.ConclusionThus, the proposed equations can be used for conversion of body composition results obtained by AUS into the BIA data.
