BCN monolayers with high theoretical capacity as anode materials for lithium-ion batteries: first-principles calculations.

The search for new anode materials with high lithium-ion battery (LIB) capacity has attracted considerable attention due to the increasing need for electrical power. Here, we utilized first-principles calculations to develop a honeycomb-structured BCN monolayer, which exhibits an ultra-high Li-ion storage capacity of 2244 mA h g as an anode material for LIBs. Furthermore, the calculations show that the BCN monolayer has a comparatively small diffusion barrier of 0.

Carbon Dots@Upconversion Nanoparticles: Conjugate Manipulation and Luminophor Confinement Enabling Aqueous-Phase Orthogonal Multicolor Phosphorescence-Upconversion Luminescence.

Developing single-particle nanocomposite with aqueous-phase orthogonal multicolor phosphorescence or multimodal luminescence holds great significance for optical coding, anti-counterfeiting encryption, bioimaging, and biosensing. However, it faces challenges such as a limited range of emission wavelengths and difficulties in controlling the synthesis process. In this work, a conjugate structure manipulation integrated luminophor confinement strategy is proposed to prepare carbon dots@upconversion nanoparticles (CDs@UCNPs) featuring aqueous-phase orthogonal multicolor room-temperature phosphorescence-upconversion luminescence (RTP-UCL) through wet-chemical synthetic methods.

Ionomic and metabolomic analyses reveal association between nutritional value and aleurone layer thickness in rice.

The fortification of aleurone cells represents a promising avenue for enhancing the nutritional quality of cereal. This study investigated dorsal aleurone thickness (DAT) in a rice diversity panel comprising 180 varieties, revealing that DAT of the Geng subspecies is typically greater than that of the Xian subspecies. The minerals and primary metabolites accumulated in the brown grains of ten rice varieties exhibiting distinct DAT were subjected to analysis using spectrometry-based technologies.

FF-ATPase Biomolecular Motor: Structure, Motility Manipulations, and Biomedical Applications.

Biomolecular motors are dynamic systems found in organisms with high energy conversion efficiency. FF-ATPase is a rotary biomolecular motor known for its near 100% energy conversion efficiency. It utilizes the synthesis and hydrolysis of ATP to induce conformational changes in motor proteins, thereby converting chemical energy into mechanical motion.

Polycystic Ovary Syndrome and the Potential for Nanomaterial-Based Drug Delivery in Therapy of This Disease.

Polycystic ovary syndrome (PCOS) is the predominant endocrine disorder among women of reproductive age and represents the leading cause of anovulatory infertility, which imposes a considerable health and economic burden. Currently, medications used to treat PCOS can lead to certain adverse reactions, such as affecting fertility and increasing the risk of venous thrombosis. Drug delivery systems utilizing nanomaterials, characterized by prolonged half-life, precision-targeted delivery, enhanced bioavailability, and reduced toxicity, are currently being employed in the management of PCOS.
