Reverse flotation of silica from Kudremukh iron ore. I. Selection of cationic reagents

open access: yes, 1997
Four types of cationic collectors were tested and evaluated for their performance in the reverse flotation of silica from the spiral preconcentrate of Kudremukh iron ore. A stagewise flotation was conducted by adding the reagent in three stages.

Dehydrocostus Lactone Suppresses Hepatocellular Carcinoma by Inhibiting Protein Tyrosine Kinase‐7 Mediated β‐Catenin Signaling

open access: yesPhytotherapy Research, EarlyView.
Schematic summary of the experimentally supported mechanism of DHL in hepatocellular carcinoma. Dehydrocostus lactone (DHL), a sesquiterpene lactone derived from Aucklandia lappa, directly engages protein tyrosine kinase 7 (PTK7), as supported by molecular docking, CETSA, and DARTS assays.

Hydrogen Bonding in Graphene

open access: yesSmall, EarlyView.
The hydrogen concentration and binding energies in large area graphene are determined from effusion measurements. The samples are grown using chemical vapor deposition using deuterated methane and deuterium as readily identifiable isotopes. Total hydrogen concentrations of 1.2 ‐ 6.9 × 1013 cm−2 are obtained.

Self‐Assembling Cationic Lipopeptides for the Construction of Functional Vesicular Gene‐Delivery Systems

open access: yesSmall, EarlyView.
Cationic lipopeptides self‐assemble into stable, cell‐like vesicles that merge peptide programmability with lipid self‐organization. These biocompatible compartments efficiently sequester and deliver nucleic acids, enabling high transfection efficiency with low‐toxicity in both HEK293T cells and mesenchymal stem cells (MSCs).

DNA‐Enzyme Hybrid Nanostructures: Functional Materials to Modulate Enzymatic Activity

open access: yesSmall, EarlyView.
DNA–enzyme hybrid nanostructures enable precise spatial and stoichiometric control over enzyme organization, offering a powerful platform to modulate catalytic activity. This review critically evaluates key mechanistic hypotheses, including proximity effects, microenvironment changes, confinement, and stabilization, as well as highlighting ...

Synthesis of Patchy Particles at Phase Boundaries

open access: yesSmall Methods, EarlyView.
The various strategies employed for synthesizing complex multifunctional patchy particles are reviewed, with, as a guideline, the type of phase boundary (solid‐gas, liquid‐gas, solid‐liquid, and liquid‐liquid), that serves as the crucial ingredient for symmetry breaking.

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

open access: yessteel 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 ...

Preclinical Toxicity Screening of Sodium Dodecanoyloxybenzenesulfonate (LOBS) as a New Alternative Biocide Using In Vitro and In Vivo Models

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Sodium hypochlorite is a well‐established biocide extensively used in both living and industrial environments; however, exposure to it or improper handling can harm the human body and the environment. Thus, safer alternatives to sodium hypochlorite are required.

Media‐Dependent Growth, Stress Responses, and Metal Accumulation Patterns in Azolla imbricata (Roxb.) Nakai Exposed to As, Cd, Cu, Pb, and Zn: Individual and Combination Effects (Synergistic, Antagonistic, and Additive)

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT In this study, we examined metal accumulation and biochemical responses of Azolla imbricata (Roxb.) Nakai exposed to water medium (WM) and nutrient medium (NM) under single and combined (co‐exposure) treatments with five metals (As, Cd, Cu, Pb, and Zn) at 10% environmentally relevant concentrations.
