Suppress Ru Over‐Oxidation Through Oxygen Vacancy Engineering – Showcase With Ni‐Modified RuO2 via Molten‐Salt Synthesis

Small, EarlyView.
Competitive OER catalyst for H2O splitting without using Ir is a luxury wish; Ru is an active element to do the job but often does not hold long. See how those scientists managed the task with Ni modified RuO2 suppressing Ru over‐oxidation through Oxygen Vacancy Engineering.

Sequential Reduction of Chromite Pellets Using Hydrogen and Silicon Carbide for Carbon Emission Abatement During Ferrochrome Production

steel research international, EarlyView.
H2 prereduction selectively metallizes Fe in UG2 chromite pellets at 1100°C, while silicon carbide becomes active at 1300°C to convert remaining Cr2O3 to carbides and promote Cr metallization. By separating the roles of H2 and SiC, the sequential route reaches up to 65.7% Cr metallization and suppresses in‐furnace CO generation by ≈75% versus ...

Multielemental Analysis in Rice Grains by Total Reflection X‐Ray Fluorescence

X-Ray Spectrometry, EarlyView.
ABSTRACT Rice (Oryza sativa) is a staple food cultivated worldwide and represents a significant source of essential nutrients for humans. However, this cereal may also contain potentially toxic elements including chromium, arsenic, and lead typically present at trace concentrations (ng.g−1).
