Detecting charge transfer at defects in 2D materials with electron ptychography. [PDF]

J Microsc
Abstract Electronic charge transfer at the atomic scale can reveal fundamental information about chemical bonding, but is far more challenging to directly image than the atomic structure. The charge density is dominated by the atomic nuclei, with bonding causing only a small perturbation. Thus detecting any change due to bonding requires a higher level

Thermodynamics Underpinning the Microbial Community-Level Nitrogen Energy Metabolism. [PDF]

Environ Microbiol
Energetically favourable nitrogen redox reactions align with community‐level networks, highlighting thermodynamic constraints shaping metabolism. Community‐level nitrogen energy metabolism shows stronger overlap with favourable reactions, suggesting selective pressure acts at the community level in microbial energy metabolism and ecosystem functions ...

Moringa stenopetala Leaves and Cafeteria Leftover as Nonconventional Supplements in the Diets of Local Gamo Sheep: Nutrient Utilization, Growth Performance and Economic Efficiency. [PDF]

Vet Med Sci
For smallholders having plenty of cafeteria leftovers and M. stenopetala leaves, blended feeding of the ingredients is more profitable than their exclusive feeding. Provided that they are comparably available, sole supplementation of M. stenopetala is more advantageous and profitable than sole supplementation of cafeteria leftovers.
