Interfacial Water Orientation in Neutral Oxygen Catalysis for Reversible Ampere-scale Zinc-air Batteries.

The neutral oxygen catalysis is an electrochemical reaction of the utmost importance in energy generation, storage application, and chemical synthesis. However, the restricted availability of protons poses a challenge to achieving kinetically favorable oxygen catalytic reactions. Here, we alter the interfacial water orientation by adjusting the Brønsted acidity at the catalyst surface, to break the proton transfer limitation of neutral oxygen electrocatalysis.

Binding Kinetics of Self-Assembled Monolayers of Fluorinated Phosphate Ester on Metal Oxides for Underwater Aerophilicity.

The term "aerophilic surface" is used to describe superhydrophobic surfaces in the Cassie-Baxter wetting state that can trap air underwater. To create aerophilic surfaces, it is essential to achieve a synergy between a low surface energy coating and substrate surface roughness. While a variety of techniques have been established to create surface roughness, the development of rapid, scalable, low-cost, waste-free, efficient, and substrate-geometry-independent processes for depositing low surface energy coatings remains a challenge.

Attitudes, beliefs and preferences surrounding home-based exercise programs in endometrial cancer patients receiving treatment.

Background: Despite recommendations, exercise participation among endometrial cancer survivors remains low. Previous interventions focused on weight loss or in-person programs with limited reach. Regular exercise, regardless of weight change, reduces mortality risk and improves functionality.

The role of cancer cell-released extracellular vesicles: have we become closer to cancer pain treatment?

The effective management of cancer pain continues to be a challenge because of our limited understanding of cancer pain mechanisms and, in particular, how cancer cells interact with neurons to produce pain. In a study published in , Inyang used a mouse model of human papillomavirus (HPV1)-induced oropharyngeal squamous cell carcinoma to show a role for cancer cell-derived extracellular vesicles (cancer sEVs) in cancer pain. They found that inhibiting the release of sEVs reduced spontaneous and evoked pain behaviors, and that pain produced by sEVs is due to activation of TRPV1 channels.

Postnatal deletion of Phlpp1 in chondrocytes delays post-traumatic osteoarthritis in male mice.

Objective: Osteoarthritis is a chronic, debilitating disease that causes long-term pain and immobility. Germline deletion of Phlpp1 or administration of small molecules that inhibit Phlpp1 prevents post-traumatic osteoarthritis (PTOA) in mice. However, the chondrocyte-intrinsic role of Phlpp1 in PTOA progression is unknown.

Compensatory effect-based oxidative stress management microneedle for psoriasis treatment.

Reactive oxygen species (ROS) at elevated levels trigger oxidative DNA damage, which is a significant factor in psoriasis exacerbation. However, normal ROS levels are essential for cell signaling, cell growth regulation, differentiation, and immune responses. To address this, we developed ROS control strategies inspired by compensatory effects.

Combined Experimental and Theoretical Approach to the Electronic and Magnetic Properties of Cu-Doped LaMnO Perovskites.

Cu-doped LaCu Mn O perovskites have been used as a model system for a joint experimental and theoretical assessment of the influence of the Cu doping level on the structural, electronic, and magnetic properties.

Electrochemical energy storage plays a critical role in the transition to clean energy. With the growing demand for efficient and sustainable energy solutions, supercapacitors have gained significant attention due to their high specific capacitance, rapid charge/discharge capabilities, long lifespan, safe operation across various temperatures, and minimal maintenance needs. This study introduces a novel approach for the synthesis of high-performance supercapacitor electrodes by using MnNi-MOF-74 as a precursor.

Rate capability and electrolyte concentration: Tuning MnO supercapacitor electrodes through electrodeposition parameters.

Manganese dioxide (MnO) is a well-known pseudocapacitive material that has been extensively studied and highly regarded, especially in supercapacitors, due to its remarkable surface redox behavior, leading to a high specific capacitance. However, its full potential is impeded by inherent characteristics such as its low electrical conductivity, dense morphology, and hindered ionic diffusion, resulting in limited rate capability in supercapacitors. Addressing this issue often requires complicated strategies and procedures, such as designing sophisticated composite architectures.

Modulating Built-In Electric Field Strength in Ru/RuO2 Interfaces through Ni Doping to Enhance Hydrogen Conversion at Ampere-level Current.

Improving the alkaline hydrogen evolution reaction (HER) efficiency is essential for developing advanced anion exchange membrane water electrolyzers (AEMWEs) that operate at industrial ampere-level currents. Herein, we employ density functional theory (DFT) calculations to identify Ni-RuO2 as the leading candidate among various 3d transition metal-doped M-RuO2 (where metal M includes Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, and Zn). The incorporation of Ni atoms facilitates the partial reduction of RuO2, resulting in the formation of a Ni-Ru/RuO2 interface having a significant built-in electric field (BIEF) during electrochemical reactions.

Multielement-Doped Tungstic Acids via Submerged Photosynthesis for Enhanced All-Solar Photoelectrochemical Responses.

Bifunctional electrode materials that can convert solar energy into electricity and store chemical energy are a functional strategy for resolving the instability of solar energy. However, most commonly used transition metal oxide semiconductor materials lack broadband wavelength absorption responses, resulting in incomplete solar energy utilization. Herein, multielement-doped MoWO·0.

Reduction-Induced Topological Phase Transition to Construct KMn[Fe(CN)] Superstructures for High-Performance Sodium-Ion Batteries.

Potassium manganese-based Prussian blue analogs (KMn-HCF) hold great potential as cathodes for sodium-ion batteries (SIBs). However, the rapid synthesis process often results in excessively small particle sizes, increasing surface area and thereby intensifying side reactions with the electrolyte, which can damage the cathode electrolyte interface (CEI) and diminish cycling stability. Herein, we designed a topological phase transition strategy to assemble small KMn-HCF particles into a 600 nm cubic superstructure.

Toward a phylogenomic classification of magnoliids.

Premise: Magnoliids are a strongly supported clade of angiosperms. Previous phylogenetic studies based primarily on analyses of a limited number of mostly plastid markers have led to the current classification of magnoliids into four orders and 18 families. However, uncertainty remains regarding the placement of several families.

Discovery of robust and highly specific microbiome signatures of non-alcoholic fatty liver disease.

Background: The pathogenesis of non-alcoholic fatty liver disease (NAFLD) with a global prevalence of 30% is multifactorial and the involvement of gut bacteria has been recently proposed. However, finding robust bacterial signatures of NAFLD has been a great challenge, mainly due to its co-occurrence with other metabolic diseases.

Results: Here, we collected public metagenomic data and integrated the taxonomy profiles with in silico generated community metabolic outputs, and detailed clinical data, of 1206 Chinese subjects w/wo metabolic diseases, including NAFLD (obese and lean), obesity, T2D, hypertension, and atherosclerosis.

Evaluation of a biomarker for amyotrophic lateral sclerosis derived from a hypomethylated DNA signature of human motor neurons.

Amyotrophic lateral sclerosis (ALS) lacks a specific biomarker, but is defined by relatively selective toxicity to motor neurons (MN). As others have highlighted, this offers an opportunity to develop a sensitive and specific biomarker based on detection of DNA released from dying MN within accessible biofluids. Here we have performed whole genome bisulfite sequencing (WGBS) of iPSC-derived MN from neurologically normal individuals.

Effects of injectable trace minerals (Se, Zn, Cu, and Mn) administration on the immune response elicited by primary intranasal modified-live virus vaccination in dairy calves.

The objective was to determine the effects of injectable trace minerals (ITM, containing Se, Cu, Zn & Mn) administered at the time of primary intranasal (IN) modified-live virus (MLV) vaccination of young dairy calves on the serum neutralizing antibody (SNA) titers to Bovine herpes virus 1 (BHV1), Bovine respiratory syncytial virus (BRSV), and Bovine Parainfluenza type 3 virus (BPIV); cytokine expression in peripheral white blood cells, and BHV1-specific IgA titers in nasal secretions following the vaccination. A total of 60 calves (1 month old) were administered an IN MLV vaccine containing BHV1, BRSV, BPIV (Inforce 3) and randomly assigned to one of two experimental groups: ITM (n = 30; Multimin90, containing Se, Cu, Zn, and Mn) or SAL (n = 30; sterile saline). There was a consistent decay in virus-specific SNA titers in both groups.

Kinetics of reformation of the S state capable of progressing to the S state after the O release by photosystem II.

The active site for water oxidation in photosystem II (PSII) comprises a MnCaO cluster adjacent to a redox-active tyrosine residue (Tyr). During the water-splitting process, the enzyme transitions through five sequential oxidation states (S to S), with O evolution occurring during the STyr· to STyr transition. Chloride also plays a role in this mechanism.
