Hierarchical PtCuMnP Nanoalloy for Efficient Hydrogen Evolution and Methanol Oxidation.

The higher amount of Pt usage and its poisoning in methanol oxidation reaction in acidic media is a major setback for methanol fuel cells. Herein, a promising dual application high-performance electrocatalyst has been developed for hydrogen evolution and methanol oxidation. A low Pt-content nanoalloy co-doped with Cu, Mn, and P is synthesized using a modified solvothermal process.

Enhanced Thermal Stability and Conductivity of FeF Using Ni-Coated Carbon Composites: Application as High-Temperature Cathodes in Thermal Batteries.

Cathode active materials and conductive additives for thermal batteries operating at high temperatures have attracted research interest, with a particular focus on compounds offering high thermal stability. Recently, FeF has been proposed as a candidate for high-voltage cathode materials; however, its commercialization is hindered by its low conductivity. In this study, conductive additives, such as Ni-coated carbon composites (multi-walled carbon nanotubes (MWCNTs) and carbon black (CB)), were utilized to enhance the thermal stability and conductivity of FeF.

FeF/(Acetylene Black and Multi-Walled Carbon Nanotube) Composite for Cathode Active Material of Thermal Battery through Formation of Conductive Network Channels.

Considerable research is being conducted on the use of FeF as a cathode replacement for FeS in thermal batteries. However, FeF alone is inefficient as a cathode active material because of its low electrical conductivity due to its wide bandgap (5.96 eV).

High Entropy Pr-Doped Hollow NiFeP Nanoflowers Inlaid on N-rGO for Efficient and Durable Electrodes for Lithium-Ion Batteries and Direct Borohydride Fuel Cells.

The selection and design of new electrode materials for energy conversion and storage are critical for improved performance, cost reduction, and mass manufacturing. A bifunctional anode with high catalytic activity and extended cycle stability is crucial for rechargeable lithium-ion batteries and direct borohydride fuel cells. Herein, a high entropy novel three-dimensional structured electrode with Pr-doped hollow NiFeP nanoflowers inlaid on N-rGO was prepared via a simple hydrothermal and self-assembly process.

Clinical Characteristics of Patients with Dental Malocclusion: An Otolaryngologic Perspective.

Allergic rhinitis (AR), which is a major cause of upper airway obstruction, may affect the development of the dental malocclusion. This retrospective study was aimed to investigate association between AR and dental malocclusion in otolaryngologic perspectives. Patients ( = 217) referred to the otolaryngology department before initiating orthodontic treatment were recruited.

Background: The effectiveness of turbinate surgery has been proven in patients with allergic rhinitis (AR).

Objectives: This study evaluated the long-term efficacy of turbinoplasty in AR and to compare the results with those of medical treatment.

Methods: This study included 192 patients diagnosed with AR who underwent surgical or medical treatment.

Anion Exchange Membranes for Fuel Cell Application: A Review.

The fuel cell industry is the most promising industry in terms of the advancement of clean and safe technologies for sustainable energy generation. The polymer electrolyte membrane fuel cell is divided into two parts: anion exchange membrane fuel cells (AEMFCs) and proton exchange membrane fuel cells (PEMFCs). In the case of PEMFCs, high-power density was secured and research and development for commercialization have made significant progress.

Pedobacter koreensis sp. nov., isolated from fresh water.

A motile, rod-shaped bacterium, designated strain WPCB189(T), was isolated from fresh water collected from the Woopo wetland (Republic of Korea). The cells were found to be Gram-negative, aerobic and catalase- and oxidase-positive. A phylogenetic analysis based on 16S rRNA gene sequences showed that this isolate forms a lineage within the genus Pedobacter, showing sequence similarities of 89.
