Abstract Oxygen vacancies (OVs) are a mixed blessing for the photoelectrochemical (PEC) water oxidation performance of monoclinic tungsten trioxide (m‐WO 3 ) photoanodes. Although it is widely accepted that moderate concentration OVs beneficial PEC m‐WO photoanodes, this argument assumes uniform distribution throughout crystal. In case, only overall needs to be considered. However, spatial non‐uniformity OV defects in photoanodes has not been thoroughly examined. study, by employing nanorod...
Fatty acids (FAs) are essential for cell survival, yet their overaccumulation causes lipotoxicity. To prevent lipotoxicity, cells store excess FAs as triglycerides (TGs). In cultured TG synthesis is activated by unsaturated but not saturated FAs. Here, we identify Ubxd8 a sensor and regulator of synthesis. depleted FAs, inhibits blocking conversion diacylglycerols (DAGs) to TGs. Excess relieve this inhibition. As result, incorporated into TGs, whereas DAGs. vitro, alter the structure...
State-of-the-art microdevice fabrication requires patterned growth of functional nanomaterials on the desired position substrate. However, it is challenging, particularly in conventional hydrothermal synthesis, due to difficulties generating a local high-temperature field at place. We introduce laser-induced (LIHG) process for rapid and selective synthesis iron oxide nanoparticles (NPs). The substrates absorb laser energy generate necessary NPs. On various substrates, dome-like structure...
Ubxd8, a multidomain protein sensor for long-chain unsaturated fatty acids (FAs), plays crucial role to maintain cellular homeostasis of FAs. Ubxd8 polymerizes upon interaction with FAs, but the molecular mechanism involved in this polymerization remains unclear. Here we report that UAS domain mediates polymerization. We show positively charged surface area is required reaction. Mutations changing residues glutamates prevented FAs from inducing oligomerization Ubxd8. Consequently, mutant no...
Passive molten salt reactors are receiving a significant amount of research attention for their inherent safety. While KCl-UCl3 exhibit high UCl3 loading 53 mol% at the eutectic composition, physical properties remain largely unexplored both forced and natural circulation. Here, we employ classical molecular dynamics simulations to calculate physicochemical salts various temperatures compositions. The computed density, heat capacity, viscosity show that only exhibits temperature dependence...
Abstract Despite its potential for clean hydrogen harvesting, photoelectrochemical (PEC) water‐splitting cells face challenges in commercialization, particularly related harvesting performance and productivity at an industrial scale. Herein, a facile fabrication method of flexible thin‐film photoanode PEC to overcome these limitations, based on laser processing technologies, is proposed. Laser‐induced graphene, carbon structure produced through direct writing carbonization (DLWC), plays dual...
Diabetes, a chronic metabolic disease affecting millions of people worldwide, necessitates the development low-cost and reliable nonenzymatic glucose sensors for effective diabetes management on global scale. This paper presents an approach using laser processing to fabricate based nanoporous Cu thin films (CuTFs). By subjecting CuO nanorod array laser-induced photoreduction (LIPR) process, highly efficient sensitive sensor is achieved through transformation into CuTF. The CuTF-based...
This review examines recent manufacturing technologies of solar water-splitting cells. It covered vacuum-based manufacturing, highlighting advances in laser-based processes and discussing their innovative potential future perspectives.
Here, we demonstrate the fabrication of a flexible and transparent micro-supercapacitor (MSC), using colorless polyimide (CPI) via direct laser writing carbonization (DLWC) process. The focused beam directly carbonizes CPI substrate generates porous carbon structure on surface substrate. Fluorine, which is one chemical compositions CPI, can enhance specific area conductivity electrode by creating micropores in structures during carbonization. Thus, fabricated carbonized CPI-based MSC shows...
Lipid droplets (LDs), once considered mere storage depots for lipids, have gained recognition their intricate roles in cellular processes, including metabolism, membrane trafficking, and disease states like obesity cancer. This review explores label-free imaging techniques' applications LD research. We discuss holotomography vibrational spectroscopic microscopy, emphasizing potential studying LDs without molecular labels, we highlight the growing integration of artificial intelligence....

Polydimethylsiloxane (PDMS) is a widely used elastomer substrate in various fields, including wearable devices, because of its diverse advantages. However, PDMS has low stretchability and lack adhesion, thus requires additive adhesives, such as conventional tapes, which can cause skin trauma. Meanwhile, polyurethane acrylate (PUA) also broadly given advantages, biocompatibility mechanical properties. This study introduces, for the first time, novel laser process method to form an...
