Investigation on the Sulfuric Acid Corrosion Mechanism for Concrete in Soaking Environment

Advances in Materials Science and Engineering, 2018
This paper chooses the apparent diffusion coefficient for OH− (hydroxyl ion) for concrete as an index to evaluate the corrosion degree of concrete subjected to sulfuric acid.

Scandium extraction from silicates by hydrometallurgical process at normal pressure and temperature

Journal of Materials Research and Technology, 2020
Silicate is an important rock-forming mineral. In this work, a method called “sulfuric acid curing” was proposed, aiming to extract rare earth element scandium from silicates.

Enhanced growth rate of atmospheric particles from sulfuric acid [PDF]

Atmospheric Chemistry and Physics, 2020
In the present-day atmosphere, sulfuric acid is the most important vapour for aerosol particle formation and initial growth. However, the growth rates of nanoparticles (<10 nm) from sulfuric acid remain poorly measured. Therefore, the effect of

Lipopolysaccharide uptake is augmented in lipopolysaccharide‐tolerant mouse macrophage‐like cells via increased CD14 expression

FEBS Open Bio, EarlyView.
In normal (nontolerant) cells, CD14 is crucial for both LPS uptake and LPS signaling. In LPS‐tolerant cells, in which LPS‐induced TNF‐α and IFN‐β production is suppressed, there is a dramatic increase in surface CD14 expression. The overexpressed CD14 in LPS‐tolerant cells is responsible for the enhanced LPS uptake without inducing pro‐inflammatory ...

From energy provision to protein synthesis: Tunnelling nanotubes as mediators of intercellular metabolic cooperation in cancer

FEBS Open Bio, EarlyView.
The cytoskeleton‐mediated transport of mitochondria via tunnelling nanotubes restores respiration, increases ATP production, rescues cells from apoptosis, activates the AKT/mTOR signalling pathway, promotes cell migration and invasiveness, contributes to cancer progression and treatment resistance.

Deprotection of Acetals and Ketals by Silica Sulfuric Acid and Wet SiO2

Molecules, 2002
Neat chlorosulfonic acid reacts with silica gel to give silica sulfuric acid in which sulfuric acid is immobilized on the surface of silica gel via covalent bonds.

BCG vaccination potentiates oxidative phosphorylation in neonatal myeloid‐derived suppressor cells

FEBS Open Bio, EarlyView.
BCG vaccination enhances oxidative phosphorylation in neonatal MDSCs, impairing their immunosuppressive function. It upregulates electron transport chain genes and mitochondrial activity, increasing ATP and oxygen consumption. Pharmacological OXPHOS inhibition partially restores suppressive capacity, confirming causality.

Preparation of Ordered Anodic Porous Alumina Films with a Sub-millimeter-scale Thickness by Anodization of Al in Oxalic Acid Containing a Small Amount of Sulfuric Acid

Electrochemistry
It was found that when an Al substrate was anodized in 0.3 M oxalic acid containing 50 mM sulfuric acid, the growth rate of the anodic porous alumina film (APAF) formed was significantly higher than that formed in an electrolyte without sulfuric acid. In

Genetic dissection of human ABCE1 in yeast reveals separable requirements for ribosome recycling and suppression of aberrant reinitiation

FEBS Open Bio, EarlyView.
Human ABCE1 cannot functionally replace its yeast ortholog. Yeast–human chimera analysis identified NBD1 as a major interspecies barrier. Genetic screening yielded hABCE1 revertants that rescue yeast viability but fail to suppress aberrant translation reinitiation in the 3′ UTR.
