Scalable all polymer dielectrics with self-assembled nanoscale multiboundary exhibiting superior high temperature capacitive performance.

Polymers are key dielectric materials for energy storage capacitors in advanced electronics and electric power systems due to their high breakdown strengths, low loss, great reliability, lightweight, and low cost. However, their electric and dielectric performance deteriorates at elevated temperatures, making them unable to meet the rising demand for harsh-environment electronics such as electric vehicles, renewable energy, and electrified transportation. Here, we present an all-polymer nanostructured dielectric material that achieves a discharged energy density of 7.

Ethnobotanical study of Zhuang medicinal herbs of Ardisia: variety systematization, traditional uses, phytochemistry, pharmacology, clinical application, and toxicity.

Objectives: This study aimed to systematize the Zhuang medicinal herbs of Ardisia (ZMHA) in China, to clarify the traditional use in Zhuang medicine and the dynamics of international research on phytochemistry, pharmacology, clinical application, and toxicity.

Key Findings: There are 25 species of ZMHA, approximately 938 compounds from the different part, including triterpenoids, phenolics, volatile oils, etc. Pharmacological activity studies have also shown that this genus has anti-tumour, anti-inflammatory, anti-oxidant, anti-bacterial, anti-microbial, etc.

Bioactivities of thymol and p-cymene from the essential oil of Adenosma buchneroides against three stored-product insects.

The adverse effects of relying solely on synthetic pesticides have become increasingly evident, leading many countries to explore alternatives sourced from plant-based green economies. Essential oil (EO) from stems and leaves of Adenosma buchneroides Bonati (A. buchneroides) was distilled by using hydrodistillation and subjected to gas chromatography-mass spectrometry (GC-MS) for component identification.

Ardisia gigantifolia stapf (Primulaceae): A review of ethnobotany, phytochemistry, pharmacology, clinical application, and toxicity.

Ethnopharmacological Relevance: Ardisia gigantifolia Stapf, known as Zou-ma-tai (in Chinese), is a traditional folk medicine, which was commonly used by Dong, Jing, Li, Maonan, Miao, Mulam, Yao, and Zhuang people. The main use of A. gigantifolia is the treatment of rheumatoid arthritis, gouty arthritis, fractures, osteoproliferation, traumatic injuries, gynecological, and neurological diseases.
