Development of Sodium-Lithium-Manganese-Cobalt Oxide with B Doping or B/F Dual Doping as Cathode Electrode Materials for Sodium-Ion Batteries.

The abundance of raw materials is a significant advantage that positions sodium-ion batteries (SIBs) as a promising energy storage solution for the future. However, the low cycle efficiency and poor rate capacity of cathode materials have hindered the commercialization of SIBs, prompting extensive research efforts to address these challenges. Ion doping into the material structure is considered to be an effective, simple, and scalable approach to enhancing the electrical performance of cathode materials.

Ultrasensitive Monitoring of Cyanide Concentrations in Water Using a Au-Ag Hybrid-Coating-Based Fiber Optical Sensor.

Cyanides, which are extremely toxic chemicals that are rapidly absorbed into the human body and interact with cytochrome oxidase, strongly inhibit cellular respiration to body death with convulsions. Cyanide ions that exist in many forms in nature such as those found in apricot kernels, cassava roots, and bamboo shoots as cyanogenic glycosides are inevitably used in various industries, including gold and silver mining as well as in dyes and plastic industries. In this study, for the sake of developing ultrahigh-sensitive sensors for cyanide monitoring in a simple manner, we chemically synthesize Au-Ag hybrid nanomaterials of different core/shell thicknesses for colorimetric sensors and fiber optical sensors.

Communicating During COVID-19: The Effect of Transparent Masks for Speech Recognition in Noise.

Objective: The purpose of this study was to assess the speech recognition in noise when using a transparent mask that allows greater visibility of the talker's face compared to an opaque mask in persons with normal and impaired hearing via an online format.
