A new natural hybrid fern, Dryopteris×subdiffracta (Dryopteridaceae), is reported from Guangxi, China. Molecular phylogenetic analysis based on DNA sequences from the low-copy nuclear marker and plastid genome revealed respectively that and are parents of the new hybrid, with as the maternal parent. Cytometric analysis of the nuclear DNA content indicated that might be a diploid hybrid. Morphologically, shares a high degree of similarity with from Taiwan, especially in zigzag-shaped rachis and deflexed pinna stalks. However, is distinguishable in the degree of lamina division and shapes of lamina and pinnulets. A comprehensive taxonomic description accompanied by line drawings are provided.

Gallium, a trace metal not found in its elemental form in nature, has garnered significant interest as a biocide, given its ability to interfere with iron metabolism in bacteria. Consequently, several gallium compounds have been developed and studied for their antimicrobial properties but face challenges of poor solubility and formulation for delivery. Organizing the metal into three-dimensional, hybrid scaffolds, termed metal-organic frameworks (MOFs), is an emerging platform with potential to address many of these limitations.

Orchidaceae is one of the largest plant families and stands out for its wide variety of flowers with ornamental and environmental importance. Cattleya is one of the main commercial genera, presenting a great diversity of species and hybrids that attract the attention of collectors, orchid enthusiasts, and consumers. In their natural environment, orchids associate with mycorrhizal fungi, which are responsible for providing carbon and other nutrients during seed germination.

Direct harvesting of abundant solar thermal energy within organic phase-change materials (PCMs) has emerged as a promising way to overcome the intermittency of renewable solar energy and pursue high-efficiency heating-related applications. Organic PCMs, however, generally suffer from several common shortcomings including melting-induced leakage, poor solar absorption, and low thermal conductivity. Compounding organic PCMs with single-component carbon materials faces the difficulty in achieving optimized comprehensive performance enhancement.

Cisplatin-based platinum compounds are important clinical chemotherapeutic agents that participate in most tumor chemotherapy regimens. Through density-functional theory calculations, the formation and stability of the inorganic oxide carrier, the mechanisms of the hydrolysis reaction of the activated platinum compound, and its binding mechanism with DNA bases can be studied. The higher the oxidation state of Pt (II to IV), the more electrons transfer from the magnesia-gold composite material to the platinum compound.
