Electrochemical preparation of peroxodisulfuric acid using boron doped diamond thin film electrodes [PDF]

, 2002
We have investigated the electrochemical oxidation of sulfuric acid on boron-doped synthetic diamond electrodes (BDD) obtained by HF CVD on p-Si. The results have shown that high current efficiency for sulfuric acid oxidation to peroxodisulfuric acid can

A proxy for atmospheric daytime gaseous sulfuric acid concentration in urban Beijing

Atmospheric Chemistry and Physics, 2019
. Gaseous sulfuric acid (H2SO4) is known as one of the key precursors for atmospheric new particle formation (NPF) processes, but its measurement remains challenging.

Effect of slag content and activator dosage on the resistance of fly ash geopolymer binders to sulfuric acid attack

Cement and Concrete Research, 2018
Geopolymer (GP) binders are an appealing alternative to Portland cement (PC) binders as they have the potential to reduce the CO2 emissions associated with the cement and concrete industry.

Multicomponent new particle formation from sulfuric acid, ammonia, and biogenic vapors

Science Advances, 2018
Atmospheric aerosol formation from biogenic vapors is strongly affected by air pollutants, like NOx, SO2, and NH3. A major fraction of atmospheric aerosol particles, which affect both air quality and climate, form from gaseous precursors in the ...

Ternary nucleation of H_2SO_4, NH_3 and H_2O [PDF]

, 2000
A classical theory of the ternary homogeneous nucleation of sulfuric acid—ammonia—water is presented. For NH3 mixing ratios exceeding 1 ppt, the presence of ammonia enhances the binary (sulfuric acid—water) nucleation rate by several orders of magnitude.

The transformations of cellulose after concentrated sulfuric acid treatment and its impact on the enzymatic saccharification

Biotechnology for Biofuels and Bioproducts, 2023
Background The dense structure of cellulose lowers its reactivity and hinders its applications. Concentrated sulfuric acid is an ideal solvent to dissolve cellulose and thus has been used widely to treat cellulose. However, the changes of cellulose after

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
