Improving low-rank coal flotation using a mixture of oleic acid and dodecane as collector [PDF]

MATEC Web of Conferences
Low-rank coals (LRC) are abundant but underutilized due to their hydrophilic nature and high oxygen content, which hinder flotation efficiency. Traditional single-collector systems often result in low recovery rates and high reagent consumption.

Adsorption‐Programmed Transformation of a Two‐Dimensional Cu–Imidazolate Framework into Mn‐Integrated Catalytic Nanonetwork

Small, EarlyView.
A freeze‐dried copper‐based metal‐organic framework removes more than 95% of manganese from water. Capturing the metal reorganizes the framework, giving the used adsorbent a second life as a reusable catalyst that produces valuable ester products in yields up to 84%.

Engineering Protein‐Polymer Hybrid Multilayer Microreactors as Antioxidant and Anti‐Inflammatory Therapeutics: Effect of Single Enzyme Nanogel Localization Within the Multilayer Systems

Small, EarlyView.
Protein‐based multilayer microreactors combine single‐enzyme nanogels (SENs) and layer‐by‐layer (LbL) assembly to control catalase localization. Positioning the enzyme within the core or at different locations of the multilayer architecture reveals how spatial organization influences antioxidant and anti‐inflammatory activity.

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 ...
