Bioinspired tactile devices can effectively mimic and reproduce the functions of the human tactile system, presenting significant potential in the field of next‐generation wearable electronics. In particular, memristor‐based bionic tactile devices have attracted considerable attention due to their exceptional characteristics of high flexibility, low power consumption, and adaptability. These devices...
Ammonia is an essential commodity in the food and chemical industry. Despite the energy‐intensive nature, the Haber–Bosch process is the only player in ammonia production at large scales. Developing other strategies is highly desirable, as sustainable and decentralized ammonia production is crucial. Electrochemical ammonia production by directly reducing nitrogen and nitrogen‐based moieties powered...
Fabrication of transition‐metal catalytic materials is regarded as a promising strategy for developing high‐performance sodium–selenium (Na–Se) batteries. However, more systematic explorations are further demanded to find out how their bonding interactions and electronic structures can affect the Na storage process. This study finds that lattice‐distorted nickel (Ni) structure can form different bonding...
The construction of high sulfur (S) loading cathode is one of the critical parameters to obtain lithium–sulfur (Li–S) batteries with high energy density, but the slow redox reaction rate of high S loading cathode limits the development process. In this paper, a metal coordinated polymer‐based three‐dimensional network binder, which can improve the reaction rate and stability of S electrode. Compared...
Replacing electrocatalytic oxygen evolution reaction (OER) with amine oxidation reaction is adopted to boost clean and environment‐friendly energy source hydrogen (H2) in water. However, the electrocatalytic reaction is severely restricted by the strong adsorption of product on the catalyst surface. Inspired by the cooperation of flavin adenine dinucleotide and mitochondria membrane in biological...
It is highly desired but challenging to design high performance catalyst for selective hydrogenation of nitro compounds into amino compounds. Herein, a boosting chemoselective hydrogenation strategy on Pt@Fe2O3 is proposed with gradient oxygen vacancy by synergy of hydrogen spillover and preferential adsorption. Experimental and theoretical investigations reveal that the nitro is preferentially adsorbed...
Liquid‐crystal small molecule donor (LC‐SMD) is a new type organic semiconductor, which is attractive not only for the easy synthesis and purification, well‐defined chemical structures, etc., but also for the LC state that makes the crystallinity and aggregation state of molecules adjustable. Here, one new LC‐SMD (a‐BTR‐H4) is synthesized with 1D alkoxyl and 2D thiophene‐alkylthiol side‐chained benzo[1,2‐...
Polymer‐based quasi‐solid‐state electrolyte (QSE) is an effective means to solve the safety problem of lithium (Li) metal batteries, and stable solid‐electrolyte‐interface (SEI) layers between electrolyte and anode/cathode are highly required for their long‐term stability. Herein, it is demonstrated that a silicon‐doped polyether functions as a multifunctional unit, which can induce the formation...
While organic–inorganic halide perovskite solar cells (PSCs) show great potential for realizing low‐cost and easily fabricated photovoltaics, the unexpected defects and long‐term stability against moisture are the main issues hindering their practical applications. Herein, a strategy is demonstrated to address the main issues by introducing lead sulfide quantum dots (QDs) on the perovskite surface...
An overview of the numerous latest research in microfiber humidity sensors is carried out with a specific focus on measurement methods, humidity sensitive materials, probe structures, and sensing properties of different sensors. First, five mainstream measurement structures, including taper, fiber grating, coupler, resonator, and interferometer are reviewed. It is concluded that these measurement...
Molybdenum sulfide/graphene composites are promising anode materials for lithium‐ion batteries (LIBs). In this work, MoSx/graphene composite film with an ideal 3D porous structure is developed via a facile and straightforward electrochemical route. The MoSx nanoparticles are uniformly anchored on the graphene nanosheets that are randomly arranged, resulting in MoSx/graphene composites with well‐developed...
The separation of organic liquid mixtures is achieved by Cu(OH)2 nanoneedle‐covered copper mesh based on the difference of the liquid surface tension. The as‐prepared membrane allows the penetration of organic liquid with smaller surface tension and blocks the higher. Thus, the effective separation of these two organic liquids can be achieved.
Integrating multiscale structural functions in one device is of great significance in water collection. So a multiscale structured membrane is designed to achieve cycle between water directional collection on the micrometer‐sized biomimetic beads and directional transport to the intersection of adjacent fibers, which endows the membrane with high efficiency and continuity in water collection.
