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.

Reducing Ammonia Emission during Food Waste Composting and Enhancing Compost Quality Using Different Additives

ChemistryOpen, EarlyView.
This research successfully reduces the ammonia emission by 45% and achieves good quality compost using additives (lactic acid or acetic acid) and bulking agents (mature compost or sawdust). The study supports Sustainable Development Goals 12 and 13 by promoting waste‐to‐resource option.

Spent Artemisia arborescens as a Biowaste Filler for Melt‐Processed PBSA Biocomposites With Enhanced Disintegration and Aerobic Biodegradation

Polymer Composites, EarlyView.
Spent Artemisia arborescens biomass, recovered after essential‐oil steam distillation, was ground and melt‐compounded with PBSA (10 and 20 wt%), yielding biocomposites with accelerated biodegradation. ABSTRACT Artemisia arborescens is a Mediterranean shrub widely used for essential oil production, generating significant amounts of spent biomass after ...

Highly selective aerobic oxidation of methane to methanol over gold decorated zinc oxideviaphotocatalysis

, 2020
Photodriven CH4 conversion has been regarded as a promising green strategy for fabrication of value-added commodity chemicals, in particular methanol. However, due to the incomplete transformation of intermediates or the overoxidation of products, a good

Cross‐Scale Engineering of Single‐Atom Catalysts from Local Planar Coordination to Spatial Architectures

Small, EarlyView.
This Review presents a cross‐scale framework for single‐atom catalysts, spanning in‐plane and out‐of‐plane coordination; primary coordination, secondary‐sphere interactions, through‐space microenvironments and support interfaces; individual sites and macroscopic architectures; and static design and directed dynamic reconstruction.
