Isotopically Selected Co‐Doping of 121Sb and 123Sb Pairs in Silicon

Advanced Materials, Volume 38, Issue 18, 25 March 2026.
Pairs of 121Sb and 123Sb atoms are doped into silicon using single cluster implantation and found to reside substitutionally within the crystal lattice due to self‐annealing with a Sb‐to Sb separation of ≈2 nm. Molecular dynamics simulations reproduce the observed experimental results and single ion cluster detection efficiencies of 94% are ...

Beyond Sabatier: Multiplicate Spillover Phenomena for Manipulating Catalytic Dynamics in Various Electrocatalysis

Advanced Science, Volume 13, Issue 13, 3 March 2026.
Various spillover‐mediated electrocatalytic reactions, such as hydrogen and oxygen evolution, carbon dioxide and nitrogen reduction, and methanol oxidization reactions, are systematically summarized. Abstract Spillover phenomenon, which is characterized by the dynamic migration of active species across catalyst surfaces, provides a promising avenue to ...

Summer‐dormant, perennial groundcover has minimal effect on plant‐available nutrients and no effect on maize yield

Agronomy Journal, Volume 118, Issue 2, March/April 2026.
Abstract Conventional agriculture in the US Midwest has accelerated crop productivity but also contributed to undesirable environmental issues. Perennial groundcovers (PGCs), such as cool‐season grasses intercropped in the maize (Zea mays L.) interrow, have the potential to reduce soil erosion rates and mitigate nutrient losses.

Separation and Identification of Impurity of Chlortetracycline Hydrochloride Not Included in the European Pharmacopoeia

Biomedical Chromatography, Volume 40, Issue 3, March 2026.
ABSTRACT Drug impurities can affect the clinical efficacy of medicines and may even present substantial health risks. Consequently, the regulation and investigation of such impurities are critically important. In this study, we observed that the chemical structure of impurity E in chlortetracycline hydrochloride, as described in the European ...
