A solid exfoliation method is developed for the synthesis of single- or few-layered (≤5 layers) graphene by ball milling of graphite with ammonia borane. Nearly quantitative yield in which ca. 25% is single-layered graphene can be obtained. We believe that this highly efficient method will offer a facile approach for the preparation of high quality and large quantity graphene.

Multiple oxygenate groups in biomass-based feedstocks are open to multiple catalytic pathways and products, typically resulting in low selectivity for the desired products. In this context, strategies for rational catalyst design are critical to obtain high selectivity for the desired products in biomass upgrading. The Sabatier principle provides a conceptual framework for designing optimal catalysts by following the volcanic relationship between catalyst activity for a reaction and the binding strength of a substrate on a catalyst.

Importance: Secondary lymphedema is a common, harmful side effect of breast cancer treatment. Robust risk models that are externally validated are needed to facilitate clinical translation. A published risk model used 5 accessible clinical factors to predict the development of breast cancer-related lymphedema; this model included a patient's mammographic breast density as a novel predictive factor.

High-fructose and high-fat diet (HFHFD) has been associated with impaired spermatogenesis, leading to decreased sperm quality and increased male infertility, with similar effects observed in offspring. Cyanidin-3-O-glucoside (C3G), a recognized food antioxidant, has shown promise in protecting in male reproduction and modulating epigenetic modifications. However, its potential role in ameliorating intergenerational inheritance induced by HFHFD remains underexplored.

Deficiency or excess of mineral elements in the environment is a primary factor limiting crop yields and nutritional quality. Lotus (Nelumbo nucifera) is an important aquatic crop in Asia, but the mechanism for accumulating mineral nutrients and coping with nutrient deficiency/excess is still largely unknown. Here, we identified NnMTP10, a member of the cation diffusion facilitator family, by screening the cDNA library of lotus.
