The application of lithium-sulfur batteries in commercial settings is impeded by their short cycle life, which arises from the formation of lithium dendrites and the loss of active material caused by polysulfide migration. Regrettably, although numerous attempts to solve these issues have been documented, the vast majority are not scalable enough to support widespread commercialization of Li-S batteries. Predominantly, the proposed methods tackle just one of the principal pathways leading to cellular impairment and decline. We showcase how incorporating the simple protein fibroin as an electrolyte additive can prevent lithium dendrite growth, reduce active material loss, and maintain high capacity and extended cycle life (exceeding 500 cycles) in lithium-sulfur batteries, all without hindering cell rate performance. By integrating experimental procedures and molecular dynamics (MD) simulations, the dual function of fibroin is revealed: it binds polysulfides to obstruct their cathode migration and protects the lithium anode from dendrite formation and expansion. Primarily, fibroin's economical nature and its ease of cellular integration via electrolytes indicate a clear path toward practical and industrial applications of Li-S batteries.

Crafting a post-fossil fuel economy hinges upon the development of sustainable energy carriers. Hydrogen, distinguished by its high efficiency as an energy carrier, is projected to be a vital alternative fuel. Therefore, the increasing desire for hydrogen production is evident in the modern age. The environmental benefit of zero-carbon green hydrogen, derived from water splitting, is offset by the expense of the catalysts required. Accordingly, the demand for catalysts characterized by both affordability and effectiveness is expanding steadily. Mo2C, and other transition-metal carbides, are objects of significant scientific inquiry, owing to their widespread accessibility and potential for superior efficiency in catalyzing hydrogen evolution reactions (HER). A bottom-up methodology is presented in this study for the deposition of Mo carbide nanostructures onto vertical graphene nanowall templates, which relies on chemical vapor deposition, magnetron sputtering, and a final thermal annealing step. The electrochemical performance enhancement stems from strategically loading graphene templates with the ideal amount of molybdenum carbides, a process meticulously regulated by the duration of deposition and annealing. In acidic environments, the resulting compounds reveal extraordinary HER activity, requiring overpotentials of more than 82 mV at a current density of -10 mA/cm2 and manifesting a Tafel slope of 56 mV per decade. The high double-layer capacitance and low charge transfer resistance of the Mo2C on GNW hybrid compounds are the principal factors responsible for their enhanced hydrogen evolution reaction (HER) activity. This investigation is projected to establish a foundation for the development of hybrid nanostructures, featuring nanocatalyst placement on three-dimensional graphene scaffolds.

Alternative fuels and valuable chemicals can be created using photocatalytic hydrogen generation, offering a promising green approach. Finding alternative, cost-effective, stable, and potentially reusable catalysts poses a lasting problem for scientific researchers in this field. Commercial RuO2 nanostructures were discovered to be a robust, versatile, and competitive catalyst for H2 photoproduction under various conditions, herein. Its inclusion in a typical three-component system allowed for a comparison of its actions with those of the widely applied platinum nanoparticle catalyst. DMEM Dulbeccos Modified Eagles Medium When using EDTA as an electron donor in water, a hydrogen evolution rate of 0.137 mol per hour per gram and an apparent quantum efficiency of 68% were recorded. Likewise, the favorable implementation of l-cysteine as the electron donor uncovers prospects unavailable to other noble metal catalysts. In organic media such as acetonitrile, the system has displayed its noteworthy adaptability through substantial hydrogen production. Recovery of the catalyst by centrifugation and its alternating reuse in diverse media confirmed its robustness.

To produce practical and dependable electrochemical cells, it is essential to develop high-current-density anodes that facilitate the oxygen evolution reaction (OER). This research focuses on the creation of a bimetallic cobalt-iron oxyhydroxide electrocatalyst, which exhibits remarkable catalytic activity for water oxidation. A bimetallic oxyhydroxide catalyst results from the use of cobalt-iron phosphide nanorods as sacrificial templates, which undergo a transformation involving phosphorous loss and the incorporation of oxygen and hydroxide. By employing a scalable synthesis method, CoFeP nanorods are produced using triphenyl phosphite as a phosphorus precursor. Nickel foam, free of binders, receives the deposition of these materials, which promotes fast electron transport, a significant surface area, and a high concentration of active sites. A comparative analysis of the morphological and chemical alterations in CoFeP nanoparticles, set against monometallic cobalt phosphide, is performed in alkaline solutions and under anodic potential conditions. A bimetallic electrode exhibiting a Tafel slope of just 42 mV dec-1 yields minimal overpotentials for oxygen evolution reaction. Utilizing a high current density of 1 A cm-2, an anion exchange membrane electrolysis device with a built-in CoFeP-based anode demonstrated, for the first time, remarkable stability and a Faradaic efficiency close to 100%. Through this work, a path is forged for the integration of metal phosphide-based anodes into practical fuel electrosynthesis devices.

Pulmonary veno-occlusive disease (PVOD), or pulmonary capillary hemangiomatosis (PCH), are infrequent causes of pulmonary hypertension. A clinical resemblance exists between pulmonary arterial hypertension (PAH) and PVOD/PCH, but PCH patients undergoing PAH therapy may experience drug-induced pulmonary edema as a side effect. For this reason, early diagnosis of PVOD/PCH is of significant value.
In Korea, we report the first case of PVOD/PCH affecting a patient with compound heterozygous pathogenic variants.
