Prussian blue analogues (PBAs) are promising electrode candidates for aqueous batteries because the inevitable interstitial water is generally thought to have little impact on battery performance. Currently, mounting researches have focused on optimizing PBA properties by varying transition metal composition, but less attention has been paid to interstitial water...
Continue readingMolybdenum disulfide (MoS2) is a high theoretical capacity (670 mAh g−1) electrode material. However, several researchers report that rechargeable batteries using MoS2 often exhibit a discharge capacity of 1000 mAh g−1 that exceeds the theoretical discharge capacity. Although various speculations are proposed, only a limited number of reports have provi...
Continue readingCarbon fibre (CF) is a lightweight next-generation material with numerous applications. CF production is predominantly based on the polyacrylonitrile (PAN) precursor because of the high tensile strength of PAN-based CFs (PAN-CFs). However, expensive and toxic organic solvents are required for PAN-CF production. Moreover, the corresponding thermal stabilisation pr...
Continue readingAccurate and continuous temperature monitoring is essential for effective diagnosis and management of health conditions, particularly amid global challenges such as the COVID-19 pandemic and the rising prevalence of age-related diseases and cancer. However, conventional temperature measuring devices suffer from inherent limitations, including rigidity, bulkiness, a...
Continue readingThe structural complexity of alkali borates, evident in the wide range of distinct structures that typically comprise these compounds, is responsible for the significant differences observed in the physicochemical properties of their corresponding melts. In this work, the structural transformations arising from carbon capture using molten lithium-sodium orthoborate...
Continue readingTemperature dependence of photocatalytic water splitting over CrOx/Rh and CoOOH cocatalyst-coloaded SrTiO3:Al codoped with Ir and Sb single-particulate photocatalysts (CrOx/Rh/SrTiO3:Ir,Sb,Al/CoOOH) under visible light irradiation was investigated. When the reaction temperature was increased from 280 to 340 K, the activity became low, and degradation became signifi...
Continue readingAs modeling of atherosclerosis requires recapitulating complex interactions with vasculature and immune cells, previous in vitro models have limitations due to their insufficient 3D vascular structures. However, induced pluripotent stem cell-derived blood vessel organoids (BVOs) are applicable for modeling vascular diseases, containing multiple cell types, includ...
Continue readingThis study presents an acetylene gas sensor capable of in situ monitoring transformer oils. This sensor utilizes carbon nanotubes (CNTs) embedded in polyimide (PI) synthesized by floating catalyst chemical vapor deposition. Unlike conventional sensors that target hydrocarbon gases dissolved in oil and measure the gas extracted from the oil, the proposed CNT-PI se...
Continue readingCrystalline α-Gd2(MoO4)3 is synthesized by sintering at 800 °C using a coprecipitation method to prepare the precursor. The resulting α-Gd2(MoO4)3 displayed a monocrystalline structure with a strong main peak (-221) in the X-ray diffraction signal. To develop a light-emitting material, rare earth ions are added during synthesis. By doping with Tb3...
Continue readingWe investigated the combinatorial synthesis and characterization of a halide perovskite CsPb(Br1−xIx)3 composition-gradient film deposited on a SrTiO3(001) substrate using infrared laser molecular beam epitaxy. In halide perovskite materials, the diffusion speed of the halogen ions is high, making it difficult to form a continuous composition-gradient film....
Continue readingBy simply increasing the concentration of electrolytes, both aqueous and non-aqueous batteries deliver technical superiority in various properties such as high-voltage operation, electrode stability and safety performance. However, the development of this strategy has encountered a bottleneck due to the limitation of the intrinsic solubility, and its comprehensiv...
Continue readingSpider dragline silk’s exceptional mechanical performance, coupled with its benign production pathway, have inspired the design of diverse smart materials. Remarkably, relatively little is known about the self-assembly process of major ampullate spidroin 1 (MaSp1) – the main protein constituent of dragline fiber – during its rapid conversion from ...
Continue readingThe findings reveal that soil constituents significantly affect the corrosion process. Moisture content and pH promote the formation of corrosion products, while high chloride concentrations accelerate corrosion. Conversely, high organic matter content inhibits corrosion by limiting oxygen diffusion to the metal surface. The effectiveness of conservation treatmen...
Continue readingExposed Mo atoms on the surface of MoS2 can catalyze certain useful chemical reactions, including the dissociation of water to produce hydrogen. However, a comprehensive understanding of water reactivity on defective MoS2 surfaces remains elusive. Here, we use in situ near ambient pressure X-ray photoelectron spectroscopy (NAP-XPS) to investigate water dissociation...
Continue readingCopper indium sulfide (CuInS2) exhibits strong visible light absorption and thus has the potential for good photocatalytic activity; however, rapid charge recombination limits its practical usage. An intriguing strategy to overcome this issue is to couple CuInS2 with another semiconductor to form a heterojunction, which can improve the charge carrier separation a...
