AbstractThe coalescence of metal nanoparticles in colloidal solutions is a universal and ubiquitous phenomenon. Using this behavior, a simple yet effective route is developed that enables the spontaneous transformation of microsized metals into nanoporous structures in specific electrolyte solvents. The criteria for selecting solvents and counterpart metals suitable for generating nanoporous structures are derived based on the classical theory of acid–base reactions and quantum chemistry based on density functional theory. When employing the developed method for anodes for Na‐ion batteries, the anodes prepared using microsized Sn, Pb, Bi, and CuS particles store 592, 423, 383, and 546 mAh g−1, respectively, at 10 C with cycling lifetimes of 3000−6000 cycles. This study provides fundamental framework for selecting solvents to realize low‐cost anodes with large capacities, long cycling lifetimes, and excellent rate performances. Moreover, the findings can be extended to other functional materials that can exploit their large specific surface areas.

AbstractSingle‐molecule photosensitizers (PSs) for synergistic phototherapy are desirable but highly challenging, due to the competitive relationship between photothermal (PTT) and photodynamic therapy (PDT). Herein, a supramolecular strategy is developed that can tune the stacking pattern of PS molecules in their aggregates to optimize the PTT/PDT efficiency. Specifically, near‐infrared (NIR) heptamethine cyanines (Cy7) are synthesized using tricyanofuran (TCF) as the acceptor and benzothiazole (BTH)/indole (IND) as the donor, where BTH is a less hydrogen‐bonded tecton relative to IND. Both IND‐Cy7‐TCF and BTH‐Cy7‐TCF have similar photophysical properties at the molecular level, but BTH‐Cy7‐TCF in aggregated state exhibits higher singlet oxygen quantum yield (1.3% vs 0.2%) and competitive photothermal conversion efficiency (56.4% vs 62.3%) compared to IND‐Cy7‐TCF, due to the fine‐tuning of hydrogen bonding and intermolecular π–π interactions to form loose molecular stacks. Interestingly, the unique molecular stacking structure provides a binding site and catalytic center for H2O2 that exhibits catalase‐like activity, which can further ameliorate the efficiency of PDT and enhance the synergistic effect of PDT/PTT phototherapy in vitro and in vivo. This study can provide a simple but effective supramolecular strategy to design small molecule PSs with desirable aggregated structure for synergistic dual‐mode phototherapy.

AbstractTopological and non‐Hermitian physics provide powerful tools for manipulating light in different ways. Recently, intense studies have converged on the interplay between topology and non‐Hermiticity, and have produced fruitful results in various photonic settings. Currently, the realization of this interplay falls under the paradigm of enabling energy exchange between topological systems and the environment. Beyond this paradigm, it is revealed that a non‐Hermitian phenomenon, i.e., the anti‐parity‐time phase transition, naturally emerges from a Hermitian system realized by coupled topological valley waveguides. Such phase transition gives two exotic topological superstates in the spectral domain. By further combining the two phases with topological robustness, a photonic topological bi‐functional device is realized on a silicon‐on‐insulator platform at telecommunications frequencies. The results provide a new perspective on light manipulation and integrated device applications.

Published: June 2023

AbstractHydrogel microrobots have blazed new avenues for local drug administration, while their values in inner ear drug delivery remain to be explored. Here, novel magnetic alpha‐lipoic acid (ALA)‐conjugated gelatin methacryloyl hydrogel microrobots are presented for inner ear drug delivery and deafness prevention. The magnetic hydrogel microrobots with features of slow drug release, targeted movement, and biosafety are generated from microfluidic devices. After intratympanic injection, the microrobots can be oriented in the middle ear cavity under a specific magnetic field. In addition, the ALA drug released from the magnetic hydrogel microrobots can remain in the inner ear for a long time. Based on these advantages, the practical value of the magnetic hydrogel microrobots in deafness prevention is demonstrated by pre‐injecting them in the middle ear of cisplatin‐deafened mice. These results indicate that the proposed smart magnetic hydrogel microrobots can effectively deliver drugs to the inner ear through the middle ear drug delivery route, thus opening a new chapter for middle ear deafness treatment.

Published: June 2023

AbstractLow‐speed flow energy, such as breezes and rivers, which are abundant in smart agriculture and smart cities, faces significant challenges in efficient harvesting as an untapped sustainable energy source. This study proposes an alternating magnetic field‐enhanced triboelectric nanogenerator (AMF‐TENG) for low‐speed flow energy harvesting, and demonstrates its feasibility through experimental results. AMF‐TENG's minimum cut‐in speed is 1 m s−1, thereby greatly expanding its wind energy harvesting range. When the wind speed is 1–5 m s−1, the open‐circuit voltage (VOC) is 20.9–179.3 V. The peak power is 0.68 mW at 5 m s−1. In a durability test of 100 K cycles, the VOC decreases from 188.4 to 174.2 V but remain at 92.5% of the initial value. furthermore, the AMF‐TENG can harvest low‐speed flow energy from the natural environment to power temperature and humidity sensors and wireless light intensity sensor in smart agriculture. This study provides a promising method for low‐speed flow energy harvesting in distributed applications.

AbstractThe importance of the clearance of dead cells is shown to have a regulatory role for normal tissue homeostasis and for the modulation of immune responses. However, how mechanobiological properties of dead cells affect efferocytosis remains largely unknown. Here, it is reported that the Young's modulus of cancer cells undergoing ferroptosis is reduced. To modulate their Young's modulus a layer‐by‐layer (LbL) nanocoating is developed. Scanning electron and fluorescence microscopy confirm coating efficiency of ferroptotic cells while atomic force microscopy reveals encapsulation of the dead cells increases their Young's modulus dependent on the number of applied LbL layers which increases their efferocytosis by primary macrophages. This work demonstrates the crucial role of mechanobiology of dead cells in regulating their efferocytosis by macrophages which can be exploited for the development of novel therapeutic strategies for diseases where modulation of efferocytosis can be potentially beneficial and for the design of drug delivery systems for cancer therapy.

Published: June 2023

AbstractDynamically tunable reflective structural colors are attractive for reflective displays (electronic paper). However, it is challenging to tune a thin layer of structural color across the full red–green–blue (RGB) basis set of colors at video rates and with long‐term stability. In this work, this is achieved through a hybrid cavity built from metal–insulator–metal (MIM) “nanocaves” and an electrochromic polymer (PProDOTMe2). The reflective colors are modulated by electrochemically doping/dedoping the polymer. Compared with traditional subpixel‐based systems, this hybrid structure provides high reflectivity (>40%) due to its “monopixel” nature and switches at video rates. The polymer bistability helps deliver ultralow power consumption (≈2.5 mW cm−2) for video display applications and negligible consumption (≈3 µW cm−2) for static images, compatible with fully photovoltaic powering. In addition, the color uniformity of the hybrid material is excellent (over cm−2) and the scalable fabrication enables large‐area production.

AbstractIonic dividers with uniform pores and functionalized surfaces display significant potential for solving Li‐dendrite issues in Li‐metal batteries. In this study, single metal and nitrogen co‐doped carbon‐sandwiched MXene (M‐NC@MXene) nanosheets are designed and fabricated, which possess highly ordered nanochannels with a diameter of ≈10 nm. The experiments and computational calculations verified that the M‐NC@MXene nanosheets eliminate Li dendrites in several ways: (1) redistributing the Li‐ion flux via the highly ordered ion channels, (2) selectively conducting Li ions and anchoring anions by heteroatom doping to extend the nucleation time for Li dendrites, and (3) tightly staggering on a routine polypropylene (PP) separator to obstruct the growth path of Li dendrites. With a Zn‐NC@MXene‐coated PP divider, the assembled Li||Li symmetric battery shows an ultralow overpotential of ≈25 mV and a cycle life of 1500 h at a high current density of 3 mA cm−2 and high capacity of 3 mAh cm−2. Remarkably, the life of a Li||Ni83 pouch cell with an energy density of 305 Wh kg−1 is improved by fivefold. Moreover, the remarkable performance of Li||Li, Li||LiFePO4, and Li||sulfur batteries reveal the significant potential of the well‐designed multifunctional ion divider for further practical applications.

Authors: Sun Jiahao , Liao Wei , Yang Zhongqiang 
Published: June 2023

AbstractLiquid crystal elastomer (LCE) exhibits large and reversible deformability originating from the alignment of liquid crystal mesogens. Additive manufacturing provides high controllability in the alignment and shaping process of LCE actuators. However, it still remains a challenge to customize LCE actuators with both diverse 3D deformability and recyclability. In this study, a new strategy is developed to exploit knitting technique to additively manufacture LCE actuators. The obtained LCE actuators are fabric‐structured with designed geometry and deformability. By accurately adjusting the parameters of the knitting patterns as modules, diverse geometry is pixel‐wise designed, and complex 3D deformations including bending, twisting, and folding are quantitatively controlled. In addition, the fabric‐structured LCE actuators can be threaded, stitched, and reknitted to achieve advanced geometry, integrated multi‐functions and efficient recyclability. This approach allows the fabrication of versatile LCE actuators with potential applications in smart textiles and soft robots.

AbstractThe perovskite compound CsPbBr3has recently been discovered as a promising room‐temperature semiconductor radiation detector, offering an inexpensive and easy‐to‐manufacture alternative to the current benchmark material Cd1−xZnxTe (CZT). The performance of CsPbBr3sensors is evaluated under harsh conditions, such as high radiation doses often found in industrial settings and extreme radiation in space. Results show minimal degradation in detector performance after exposure to 1 Mrad of Co‐60 gamma radiation, with no significant change to energy resolution or hole mobility and lifetime. Additionally, many of the devices are still functional after being exposed to a 10 Mrad dose over 3 days, and those that do not survive can still be refabricated into working detectors. These results suggest that the failure mode in these devices is likely related to the interface between the electrode and material and their reaction, or the electrode itself and not the material itself. Overall, the study suggests that CsPbBr3has high potential as a reliable and efficient radiation detector in various applications, including those involving extreme fluxes and energies of gamma‐ray radiation.

Published: June 2023

AbstractThe development of horizontal drilling and hydraulic fracking has led to an increase in oil and natural gas extraction. Development of infrastructure to extract and transport these resources is expected to increase over the next few decades, resulting in extensive land disturbance. Although reclamation aims to sufficiently return disturbed lands to their pre‐disturbance use in an ecological sense, reclaimed rights‐of‐ways (ROW) commonly produce reduced crop yields. The objective of this study was to use meta‐analysis to determine soil disturbance trends across studies found in the peer‐reviewed literature. Papers that reported soil property data on disturbed ROWs and adjacent undisturbed sites were retrieved by searching the Web of Science database. Papers were separated by climate regions, resulting in analyses being conducted for studies in semiarid and humid climate regions. Results indicate that soil bulk density, soil organic matter, and pH are significantly increased on reclaimed ROWs. Soil metrics not incorporated in meta‐analysis due to insufficient observations or the possible presence of publication biases like a desire to publish significant results and poor study design (cation exchange capacity, calcium, phosphorus, magnesium, total nitrogen, electrical conductivity, sodium, sodium adsorption ratio, and texture) are assessed and discussed. Best management practices gleaned from studies incorporated into meta‐analysis are discussed to provide strategies to limit soil property disturbances.

AbstractThe use of legumes for cultivation in mixtures with cereals has a positive effect not only on the yield of green mass but also on its chemical composition. This research evaluated the influence of different seeding rate proportions of field pea (Pisum sativum L.) with spring triticale (×Triticosecale Wittm.) at different growth stages on Fe and Mn contents in soil and plants. The two factors examined in the study were as follows: proportional seeding rate of components in the mixture (kg ha−1)—field pea/spring triticale 240:0, 180:55, 120:110, 60:165, and 0:220; and harvest stage—field pea flowering versus field pea flat green pod. The greatest soil contents of Fe at 952 mg kg−1 and Mn at 102.2 mg kg−1 were found in the soil at 0–30 cm depth following harvest of field pea. The greatest dry matter concentrations of Fe at 146 mg kg−1 and Mn at 68.5 mg kg−1 in the mixtures were determined in the forage of field pea/spring triticale at 180:55 harvested at the field pea flat green pod stage. The field experiment demonstrated that a 180:55 mixture of pea and spring triticale should be recommended for cultivation. This mixture provides the greatest Fe and Mn content in soil and forage for cattle.

AbstractThe polygonal multifocal propagation properties and particle trapping experiments of a new kind of power‐exponential‐phase vortex chirped circular Pearcey Gaussian beam are investigated. Theoretical and experimental results show that it is possible to adjust the position and transverse spatial distribution of the beam in focal plane, as well as to make the transverse intensity distribution emerge an arbitrary polygonal profile by changing the distribution factor and vortex topological charge. Stable trapping of multiple particles is achieved in the experiment with transverse intensity fields in the polygon plane with different topological charges.

Published: June 2023

AbstractDue to their important roles in medicine, the product of the Petasis reaction has attracted extensive interest in pharmaceutical, medical and chemical communities. Traditional three‐component Petasis methods normally use various catalysts under harsh conditions (high temperature, microwave, etc.) for long reaction times. In this study, we developed a green and highly efficient microdroplet method for accelerating the Petasis reaction, which obtain good yields without the need of any catalysts under mild reaction conditions. The Petasis reaction in microdroplets was suitable for a variety of salicylaldehydes, arylboronic acids and amines. The Petasis reaction in microdroplets was accelerated by approximately 4 orders of magnitude by comparing the measured rate constants in bulk. Further, a scaled‐up amount of 0.8 g h−1 was achieved for the Petasis reaction in microdroplets. This study supplies not only a high‐efficiency and environment‐friendly methodology to constructing aryl amines in organic community but also a useful derivatization strategy for highly sensitive mass spectrometric detection of arylboronic acids and aryl aldehydes.

Published: June 2023

AbstractIn this Application Note, a versatile and reliable measurement system for photoelectrochemical investigations is described which aims to assist scientists in obtaining reproducible photoelectrochemical data of high quality, including the solar‐to‐hydrogen (STH) efficiency. Specifically, it addresses the parameters irradiation quality, reaction temperature, and gas measurement. The setup is designed to exclude stray light and uses a solar‐grade mirror to reflect the light of a vertical solar simulator on the electrochemical cell. The light quality in the setup (»AAA«, IEC 60904‐9) is close to the classification of the solar simulator itself. The temperature in the electrochemical cell is controlled with an external Peltier element and can be kept constant in the range of 20–45°C. The influence of reaction temperature on the photocurrent of a WO3 photoanode is demonstrated. The gaseous reaction products are analyzed with a mobile gas chromatograph, using an automated measurement routine with discontinuous sampling from the electrochemical cell. The system is applied to determine the Faraday and STH efficiencies of a copper indium gallium selenide photocathode.

AbstractWith the rapid growth of secondary batteries used in various industries, methods for analyzing battery elements such as electrodes and electrolytes have also improved. In addition, as the utility of nano‐scaled electrode materials have attracted greater attention, it has become increasingly clear that conventional electrochemical analytic methods have limitations. Consequently, electron microscopy and even synchrotron x‐ray radiation techniques have been adopted and are now widely used. Among several advanced analytical techniques, synchrotron radiation‐based operando small‐angle x‐ray scattering (SAXS) enables real‐time analysis of changes in the ordering of nanostructures and in the electron densities of electrodes and solid electrolytes during electrochemical reactions. In this review, the principle and applications of operando SAXS are briefly introduced, to help in understanding the complex nanostructural behaviors of battery components used in secondary batteries, and furthermore, it is hoped to contribute to innovative materials design.

Published: June 2023

AbstractAdhesives that can switch their total adhesion strength on‐demand are a new class of materials and can have a broad utility in biomedicine and microelectronics, among others. Total adhesion strength can be modulated by the physical or chemical changes of materials induced by external stimuli, such as light, heat, or chemical species. A covalent adaptive network is a crosslinked polymer network whose topology or covalent connectivity changes in response to a stimulus (usually heat) and thus can alter its adhesive properties. In this review, we highlight recent developments in covalent adaptive networks utilized in switchable adhesives. Furthermore, we discuss the mechanisms of covalent bond exchange (associative or dissociative), focusing on molecular design to affect the total adhesion strength and reversibility, as well as unique features that can be leveraged for future adhesives.
