Cellulose nanocrystal composite films for contactless moisture-electric conversion.

The ability to convert moisture signals into electrical signals through contactless control underpins a wide range of applications, including health monitoring, disaster warning, and energy harvesting. Despite its potential, the effective utilization of low-grade energy remains challenging, as it often requires complex device architectures that limit scalability and integration, particularly in wearable technologies. Here, we present a soft, flexible moisture-electric converter made from cellulose nanocrystals and polyvinyl alcohol composite films, designed for a novel touchless interactive platform.

Synergistic Intramolecular Charge Transfer Promotes Au Nanoclusters with Enhanced NIR-II Photoluminescence.

Gold nanoclusters (Au NCs) protected by molecular ligands represent a new class of second-generation near-infrared (NIR-II) luminescent materials that have been widely studied. However, the photoluminescence efficiencies of most NIR-II emitting Au NCs in aqueous solution are generally lower than 0.2%, and to fully exploit the advantages of AuNCs in the NIR-II region, improving their photoluminescence efficiency has become an urgent need.

Integrative Omics Analysis Reveals Mechanisms of Anthocyanin Biosynthesis in Djulis Spikes.

Djulis ( Koidz.), a member of the family plant, is noted for its vibrant appearance and significant ornamental value. However, the mechanisms underlying color variation in its spikes remain unexplored.

Drosophila modeling to identify causative genes and reveal the underlying molecular mechanisms for primary ovarian insufficiency.

Primary ovarian insufficiency (POI) is a disease defined as a reduction in ovarian function under the age of 40 and represents the main cause of female infertility. In recent years, many genetic mutations associated with POI have been identified using high-throughput sequencing technology. However, one big challenge today is to determine the disease-causing gene associations through functional assessment.

Interaction effect of mobile gaming addiction and excessive sugar-sweetened beverage consumption on overweight and obesity among schoolchildren: Evidence from a large population-based study in Guangzhou, China.

Objective: To explore the individual and interactive associations between mobile gaming addiction (MGA), excessive consumption of sugar-sweetened beverages (SSBs), and overweight/obesity among schoolchildren, and to investigate whether these interactions vary by gender or grade level.

Methods: Data were drawn from the Children's Growth Environment, Lifestyle, and Physical and Mental Health Development project (COHERENCE) conducted in Guangzhou, China, during the 2019/20 academic year. 418,197 children aged 6-12 years were included in the study.
