Hollow urchin-like MnO microspheres as an advanced sulfur host for enabling Li-S batteries with high gravimetric energy density.

Lithium-sulfur (Li-S) batteries are considered to be promising candidates for next-generation storage systems. However, the practical applications are still hindered by the severe capacity decay, mainly caused by the large volume change, polysulfide shuttle and sluggish sulfur conversion kinetics. Herein, hollow urchin-like MnO (HU-MnO) microspheres as sulfur hosts have been synthesized by the hydrothermal method and calcination treatment, aiming to prevent the polysulfide dissolution (benefiting from the strong polysulfide anchoring effect of MnO) and alleviate the volume expansion of sulfur (benefiting from the special hollow structure).

Improved 1D convolutional neural network adapted to near-infrared spectroscopy for rapid discrimination of Anoectochilus roxburghii and its counterfeits.

Anoectochilus roxburghii (Wall.) Lindl. (Orchidaceae) is a rare traditional Chinese medicine.

A Review of the Discriminant Analysis Methods for Food Quality Based on Near-Infrared Spectroscopy and Pattern Recognition.

Near-infrared spectroscopy (NIRS) combined with pattern recognition technique has become an important type of non-destructive discriminant method. This review first introduces the basic structure of the qualitative analysis process based on near-infrared spectroscopy. Then, the main pretreatment methods of NIRS data processing are investigated.

Assessment of variation in paddy microbial communities under different storage temperatures and relative humidity by Illumina sequencing analysis.

Temperature and relative humidity are important conditions in paddy storage; however, their influence on microbial communities in stored paddy remains poorly understood. In this study, paddy was stored at different temperatures and relative humidity, and severe mildew was observed in samples stored at relative humidity of 97% and different temperatures (15, 28, and 37 °C) after 50 days. High-throughput 16S rRNA and ITS genes amplicon sequencing analyses showed that Proteobacteria, Firmicutes, and Ascomycota were the dominant phyla across the paddy samples.
