Optimizing feather hydrolysate via machine learning for microbial recycling of waste concrete fines
Journal of Chemical Technology &Biotechnology, EarlyView.Abstract BACKGROUND The concrete industry faces significant challenges from CO2 emissions and the disposal of waste concrete fines (WCF). Microbially induced calcite precipitation (MICP) can bind WCF into bioconcrete, but the high cost of commercial culture media hinders its application.

The German Soil Systematics and the Rationale Behind Its Revision
Journal of Plant Nutrition and Soil Science, EarlyView.ABSTRACT Background The German Soil Systematics is a pedogenetic classification based on the morphological expressions of pedogenic processes and has been developed over several stages since 1952. The system has successfully been in use for soil classification and soil survey for almost 70 years.

Foamed Concrete Sealing Materials for Coal Seam Gas Drainage Boreholes: A Review
Safety Science and Technology, EarlyView.This study investigates the sealing performance of foamed concrete in gas drainage boreholes. By comparing leakage pathways (a, c) with sealed systems (b, d), the research demonstrates how foamed concrete effectively fills mining‐induced fractures and resists deformation.
