Study on the associative effects of different proportions of soybean pod, alfalfa and concentrate on the diets at different ratio of concentrate to roughage in vitro

open access: yesCzech Journal of Animal Science, 2020
This study aimed to determine the associative effects (AEs) of 28 feed combinations of concentrate/soybean pod/alfalfa at different concentrate-roughage ratios that were incubated for 72 h in single tubes (120 ml) which were added 30 ml rumen buffered ...

Can Mixed Intercropping Protect Cereals from Aphid-Borne Viruses? An Experimental Approach

open access: yesInsects, 2022
Intercropping, i.e., association of two or more species, is promising to reduce insect populations in fields. The cereal aphid Rhopalosiphum padi, a vector of the Barley yellow dwarf virus PAV (BYDV-PAV), represents a major threat for cereal grain ...

Stabilization of Strongly Reduced Fe(I) Single Atom Species Coordinated in a 2D Self‐Assembled Metal–Organic Network

open access: yesAdvanced Functional Materials, EarlyView.
A graphene‐supported 2D metal–organic network stabilizes highly reactive Fe(I)‐N4 single sites through Co‐induced charge redistribution. Combined experiments and theory reveal Fe(I) formation, oxygen‐driven oxidation, and O2 activation mechanisms, offering a strategy to access low‐valent iron centers relevant to catalytic and biological processes ...
