AbstractThe prospects of endowing artificial robotics or devices with increasingly complex and emergent life‐like behaviors have attracted growing interest in the soft functional materials that mimic the versatile motions of living creatures in the iridescent nature. However, despite the flourishing achievements so far, soft actuators capable of sensitive multi‐stimulus responses and self‐sustainable movements, have been extensively pursued to reduce control complexity yet remains a challenging target. Here, through material‐structural synergistic design incorporating stress‐mismatching structure, high pseudo‐negative coefficient of thermal expansion of perfluoro‐sulfonic acid ionomer, comprehensive converting properties of carbon nanotube, and anisotropic large thermal expansion of PE polymer, an ionomer‐based bilayer actuator is proposed, presenting high‐performance actuation of various forms and nice stability, responsive to light (including sunlight without focusing, LED light), low voltage, mild heating, and humidity/solvent change. With a built‐in structural feedback loop, the actuation performances are further explored to realize intelligent systems, including: 1) self‐sustainable locomotion under sunlight irradiation with adjustable photophobic and phototropic direction as well as adaption to different topographies and loading conditions, 2) self‐sustainable oscillation and solar‐electric generating, and 3) bionic floristic reaction according to environmental change. These diversified actuation modes allow promising following‐up designs for bio‐hybrid soft robotics fueled by and harmonized with natural environments.

AbstractWound healing is a complex biological process involving close crosstalk between various cell types. Dysregulation in any of these processes, such as in diabetic wounds, results in chronic nonhealing wounds. Fibroblasts are a critical cell type involved in the formation of granulation tissue, essential for effective wound healing. 315 different polymer surfaces are screened to identify candidates which actively drive fibroblasts toward either pro‐ or antiproliferative functional phenotypes. Fibroblast‐instructive chemistries are identified, which are synthesized into surfactants to fabricate easy to administer microparticles for direct application to diabetic wounds. The pro‐proliferative microfluidic derived particles are able to successfully promote neovascularization, granulation tissue formation, and wound closure after a single application to the wound bed. These active novel bio‐instructive microparticles show great potential as a route to reducing the burden of chronic wounds.

Micro‐optics realized via MPL emerged a decade ago and the field has exploded during the last five years. Impressive findings have revealed its potential for beam shaping, advanced imaging, optical sensing, integrated photonic circuits, and much more. This is supported by a game‐changing and increasing industrial interest from key established companies in this field. In this review, the origin and the advancement of micro‐optics fabrication with MPL are detailed by describing the chronology, distinguishing discrete application groups, providing generalized technical data on the processes and available materials, and discussing the foreseen near‐future advances.

Published: November 2022

AbstractLight‐trapping elements play an important role in solar cells to enhance their light‐harvesting efficiency. Pyramidal‐shaped nano‐microstructures and gradient metasurfaces are mostly used as light‐trapping elements in solar cells. There is, however, one major concern with nanostructured solar cells: a larger surface area resulting in a larger surface recombination loss. In this article, a novel thin‐film wedge tandem‐solar cell made of perovskites and silicon is designed where the bottom cell itself works as a light‐trapping element. Optical and electrical simulations are performed to estimate performance metrics of the wedge tandem‐solar cell and compare with typically used unpatterned planar tandem‐solar cell. In terms of optical and electrical performance, wedge geometry outperforms planar geometry and shows 17.18% higher efficiency. Compared to a typical planar tandem cell, such a design can lead to thin and low‐weight tandem solar cells, which can be very useful in space applications. The proposed design can be fabricated using an optimized electrospray deposition process.

AbstractCancer immunotherapy effect can be greatly enhanced by other methods to induce immunogenic cell death (ICD), which has profoundly affected immunotherapy as a highly efficient paradigm. However, these treatments have significant limitations, either by causing damage of the immune system or limited to superficial tumors. Sonodynamic therapy (SDT) can induce ICD to promote immunotherapy without affecting the immune system because of its excellent spatiotemporal selectivity and low side effects. Nevertheless, SDT is still limited by low reactive oxygen species yield and the complex tumor microenvironment. Recently, some emerging SDT‐based nanomedicines have made numerous attractive and encouraging achievements in the field of cancer immunotherapy due to high immunotherapeutic efficiency. However, this cross‐cutting field of research is still far from being widely explored due to huge professional barriers. Herein, the characteristics of the tumor immune microenvironment and the mechanisms of ICD are firstly systematically summarized. Subsequently, the therapeutic mechanism of SDT is fully summarized, and the advantages and limitations of SDT are discussed. The representative advances of SDT‐based nanomedicines for cancer immunotherapy are further highlighted. Finally, the application prospects and challenges of SDT‐based immunotherapy in future clinical translation are discussed.

AbstractChlorinated volatile organic compounds (CVOCs) are a class of hazardous pollutants that severely threaten environmental safety and human health. Although the catalytic oxidation technique for CVOCs elimination is effective, enhancing the catalytic efficiency and simultaneously inhibiting the production of organic byproducts is still of great challenge. Herein, Ru‐substituted LaMn(Ru)O3+δ perovskite with Ru–O–Mn structure and weakened Mn–O bond strength has been developed for catalytic oxidation of chlorobenzene (CB). The formed Ru–O–Mn structure serves as favorable sites for CB adsorption and activation, while the weakening of Mn–O bond strength facilitates the formation of active oxygen species and improves oxygen mobility and catalyst reducibility. Therefore, LaMn(Ru)O3+δ exhibits superior low‐temperature activity with the temperature of 90% CB conversion decreasing by over 90 °C compared with pristine perovskite, and the deep oxidation of chlorinated byproducts produced in low temperature is also accelerated. Furthermore, the introduction of water vapor into reaction system triggers the process of hydrolysis oxidation that promotes CB destruction and inhibits the generation of chlorinated byproducts, due to the higher‐activity *OOH species generated from the dissociated H2O reacting with adsorbed oxygen. This work can provide a unique, high‐efficiency, and facile strategy for CVOCs degradation and environmental improvement.

Published: November 2022

AbstractAlkali metals (i.e., Li, Na, and K) are promising anode materials for next‐generation high‐energy‐density batteries due to their superior theoretical specific capacities and low electrochemical potentials. However, the uneven current and ion distribution on the anode surface probably induces undesirable dendrite growth, which leads to significant safety hazards and severely hinders the commercialization of alkali metal anodes. A smart and versatile strategy that can accommodate alkali metals into porous metal current collectors (PMCCs) has been well established to resolve the issues as well as to promote the practical applications of alkali metal anodes. Moreover, the proposal of PMCCs can meet the requirement of the dendrite‐free battery fabrication industry, while the electrode material loading exactly needs the metal current collector component as well. Here, a systematic survey on advanced PMCCs for Li, Na, and K alkali metal anodes is presented, including their development timeline, categories, fabrication methods, and working mechanism. On this basis, some significant methodology advances to control pore structure, surface area, surface wettability, and mechanical properties are systematically summarized. Further, the existing issues and the development prospects of PMCCs to improve anode performance in alkali metal batteries are discussed.
Triggering the Phase Conversion of GeP from Monoclinic to Cubic by Zn Substitution toward a High‐Rate Ge1−xZnxP Solid Solution Anode for Li‐Ion Batteries

AbstractThe monoclinic GeP with large capacity, low plateau, and high initial coulombic efficiency (ICE) has been proved to be alternative anode for Li‐ion batteries. However, the heavy use of Ge raw material with its high price, hinders its further development. Herein, the Zn atom is proposed for substitution into GeP and replaces part of the Ge owing to its low price, suitable plateau, and similar radius. Interestingly, a novel Ge1−xZnxP solid solution with a wide range tunable region (0.143 < x < 0.6) is achieved, reducing the heavy use of Ge and cutting the GeP price down. More intriguingly, such Ge1−xZnxP possesses a new phase, different from monoclinic GeP, which is first verified to be a cubic system in F‐43m. Compared to semi‐conducting GeP, this cubic Ge1−xZnxP phase possesses metallic conductivity, thus enabling a better rate performance than monoclinic GeP (e.g., 881 vs 283 mAh g−1 at 2000 mA g−1), while keeping the great advantages of large capacity, low plateau, and high ICE of GeP as well. Consequently, the assembled LiCoO2//Ge1−xZnxP full cell exhibits large capacity over 1000 mAh g−1. This unique phase control strategy by atomic substitution can be easily extended to manipulate electrochemical behaviors of other multi‐phase materials toward advanced energy storage.

AbstractDespite their high electrocatalytic activity for oxygen electrode reactions, the low phase stability and high thermal expansion of perovskite structured materials have created difficulties in cell fabrication scale‐up and long‐term operational stability of reversible ceramic cells. Herein, an exceptionally high‐performance electrocatalyst is presented based on a misfit‐layered structure, Na0.15Ca2.85Co4O9–δ (NCCO). NCCO cells enable exceptional fuel cell performance down to 400 °C, with peak power densities of 0.18–5.15 W cm−2 at 400–800 °C, as well as electrolysis performance of minus current density 5.96–15.07 A·cm−2 (at 1.4 V) at 600–750 °C, exceeding the values of all previously described reversible (oxygen and proton) ceramic cells. Furthermore, the durability of NCCO cells is demonstrated for over 900 h at high current densities of 1 and 2 A cm−2 in fuel cells and –0.5 and –4 A cm−2 electrolysis cell modes under load cycle and constant current reversible operation, respectively. Doping with basic monovalent Na+ ions in the Ca‐site in Ca3Co4O9+δ generates a high density of extra charge carrier species with the increased Co oxidation state and facilitates the proton uptake and diffusion properties of misfit‐layered materials. This finding can deliver a new opportunity to develop innovative bifunctional oxygen electrode catalysts, while providing more favorable reaction pathways for the diffusion of charged species.

AbstractObjectivesAge is associated with a number of health risks linked to obesity caused by an imbalance in the main energy substrates—fatty acids (FA) and glucose (Glu). Therefore, the objective of this study was to identify age‐related features of the metabolism of fatty acids and Glu, their correlations and the relation with the body mass index (BMI) in women of the local Caucasoid population from two northern regions of Russia with different nature, climate, and geography.MethodsWe examined women aged 21–60 years born and permanently residing in the Subarctic region (SR) and the Arctic region (AR). The participants were divided into three age groups: 21–35, 36–45, and 46–60 years. The levels of FAs, Glu, and triglycerides (TG) in the blood serum were determined by spectrophotometric and gas chromatographic methods; the values of BMI and TyG (triglyceride glucose) index were calculated. To analyze data, we used the descriptive and correlation analyses by nonparametric methods, as well as multiple linear regression analysis.ResultsWith age, the surveyed women demonstrated elevated levels of triglyceride, the majority of the studied fatty acids, BMI and TyG index. For three fatty acids, age‐related changes were noted in one of the regions only: stearic and linoleic acids in the SR, and docosahexaenoic acid in the AR; no significant changes were observed for dihomo‐γ‐linolenic and arachidonic acids. We found elevated Glu levels in women aged 46–60 years residing in the SR. Regional differences were due to higher concentrations of FAs and Glu in the AR. All identified correlations were positive. BMI values were associated with FAs and TG, and in women aged 46–60 years, they were additionally associated with Glu. The latter also correlated with some FAs and TG in this group. TyG index associations with saturated FAs (SFAs) became stronger with age.ConclusionsAge has a significant impact on the homeostasis of key energy substrates (Glu, TG, SFAs, monounsaturated FAs), on BMI and TyG index, which are indicators of obesity and insulin resistance. Depending on the region of residence (Subarctic or Arctic), we found changes in the FA profile undersaturation (especially long‐chain polyunsaturated FAs) and some specific features of Glu homeostasis (for the age groups of 21–35 and 46–60 years) in women of Caucasoid race in the Russian North. Multiple regression analysis showed that BMI, as well as the region of residence and age, are significant predictors for almost all biochemical parameters, especially for TG and TyG index.

Published: November 2022

AbstractThis article studied the mechanism of the influence of light‐curing 3D forming parameters of acrylic resin on its tribological and mechanical properties. A three‐factor hybrid orthogonal table was designed, that is, the three key process parameters of printing monolayer thickness (P), heat treatment (H), and ultraviolet curing treatment (U). The priority of three process parameters affecting tribological performance was studied based on Gray Correlation Theory. The results showed that the order of priority was P, U, and H. The tribological and mechanical properties of acrylic resin decreased with the increase of printing monolayer thickness, while the printing efficiency increased with the increase of the printing monolayer thickness. Based on Gray Correlation Theory, the “Wear Resistance Efficiency” (WRE) parameter was defined to comprehensively evaluate the wear resistance and printing efficiency of the samples. When the thickness of the printing monolayer was 30 μm, the comprehensive properties of the material reached the optimal value. The U increased the cross‐linking degree of the acrylic interlayer molecules, and the H reduced the residual stress generated during the printing of the samples. The research results provided data support for the application of 3D printing acrylic resin and its nanocomposites in the field of tribology.

Published: November 2022

AbstractIn this work, graphene/zinc oxide nanoparticles (G/ZnO NPs) were synthesized by a metathesis‐assisted molten salt route. The methodology followed has outstanding features such as innovative, environmentally friendly, high‐yield, efficient, and straightforward. In addition, poly(ether‐block‐amide) (PEBA)‐based mixed matrix membranes (MMMs) filled with different amounts of G/ZnO NPs (up to 2%) were successfully prepared. Thermogravimetric analysis and X‐ray diffraction were performed to determine the thermal and structural properties of the pristine and MMMs. Scanning electron microscopy and electron dispersive spectroscopy were used for morphological studies and for identifying the as‐prepared G/ZnO NPs. Incorporating G/ZnO NPs (PEBA‐G/ZnO 2% 476 Barrer) provided benefits to the permeability properties and showed an increase of 37% concerning the polymeric membrane (318.06 Barrer). The gas separation performance improved by increasing the amount of G/ZnO NPs. A synergistic effect between PEBA properties and G/ZnO NPs led to enhanced CO2 selectivity for ternary mixed gas separation (CO2/CH4/N2). Selectivity of the MMMs showed an increase of 34% higher than to pristine (PEBA) membrane favoring the permeation of CO2. G/ZnO NPs can be potentially helpful in membranes applied in the CO2 mixed gas separation.

Abstract

The Big Seaweed Search invites people to survey UK seashores for 14 conspicuous seaweeds. The science investigates: (i) impact of sea temperature rise; (ii) spread of non‐native species; and (iii) impact of ocean acidification. Survey data submitted between June 2016 and May 2020 were analysed to evaluate and explore project directions in relation to citizen science project development.
Of the 378 surveys submitted, 1,414 people participated, contributing 1,531 person hours. Surveys were undertaken around the UK, with the highest proportion (46.7%) in the south west and the lowest (3.7%) in the north east.
After data verification, 1,007 (54%) records were accepted. Fucus serratus had the highest number of entries correctly identified (66%) and Undaria pinnatifida the lowest (5%), inferring that at least some seaweeds can be difficult to identify, although the overall misidentification rate was relatively low (c. 15%).
Apart from Alaria esculenta, U. pinnatifida and Saccharina latissima, the large brown seaweeds were abundant on at least some shores. Non‐natives Sargassum muticum and Asparagopsis armata, were band‐forming but in low numbers. Coralline algae, whilst band‐forming on some shores, were most commonly patchy or sparse in abundance. Revisits, i.e. repeat surveys, at the same site with an interval of at least 1 year, are relatively low, with 18 sites revisited once and three sites revisited twice. Currently, data are insufficient to determine whether any changes in abundance could be detected.
This study highlights areas where project developments can enhance data quality and quantity, e.g. better identification resources, training programmes for dedicated volunteers, and an annual focus week of activities. The project framed around climate change impacts, aims to raise awareness of the ecological importance of, and threats faced by, this understudied habitat and introduce conservation concepts including the need to protect common species showing signs of decline.
