Effects on soil carbon storage from municipal biosolids application to agricultural fields.

This study investigated the influence of biosolid applications on soil carbon storage and evaluated nutrient management strategies affecting soil carbon dynamics. The research assessed alterations in soil pH, soil carbon stock, and soil nitrogen content within short-term and long-term biosolids-amended soils in Bible Hill, Nova Scotia, Canada, extending to a depth of 0-60 cm. The findings indicated an increase in soil pH with alkaline treatment biosolids (ATB) applications across both study sites, with a legacy effect on soil pH noted in the long-term biosolids-amended soil following a single ATB application over 13 years.

Facile fabrication of novel konjac glucomannan films with antibacterial properties via microfluidic spinning strategy.

The exploration of methods to produce biomaterials with antibacterial properties in ultra-small scales is of great scientific and technological interest. Here, we reported a microfluidic spinning approach to prepare a novel film combined with konjac glucomannan (KGM), polyvinylpyrrolidone (PVP), and epigallocatechin gallate (EGCG). The film was characterized by scanning electron microscopy, Fourier transform infrared spectroscopy, X-ray diffraction, and thermogravimetric analysis.
