Adv Colloid Interface Sci. 2015 Dec;226:138-65. doi: 10.1016/j.cis.2015.10.007. Epub 2015 Oct 19.

Charging effects resulting from adsorption of acid, acid anions, and protons on titania (anatase) surfaces in anhydrous or mixed alcohol-water dispersions is summarized. The suddenly enhanced conductivity as compared to titania-free solutions has previously been modeled and explained as...

Hague JL, Machlan LA.
PMID: 32196199
J Res Natl Bur Stand A Phys Chem. 1961 Jan-Feb;65(1):75-77. doi: 10.6028/jres.065A.008. Epub 1961 Feb 01.

The results of a systematic survey of the elution of hafnium and zirconium in diluted sulfuric acid, and in solutions of hydrochloric and sulfuric acids in water, are presented. The data characterize the behavior of the sulfate anion complexes...

Nonacid nitration of benzenedicarboxylic and naphthalenecarboxylic acid esters.

The Journal of organic chemistry

Nose M, Suzuki H, Suzuki H.
PMID: 11397177
J Org Chem. 2001 Jun 15;66(12):4356-60. doi: 10.1021/jo015619d.

When treated with nitrogen dioxide in the presence of ozone and a catalytic amount of iron(III) chloride in inert organic solvent at -10 to +5 degrees C, benzenedicarboxylic acid diesters 1, 4, and 6 underwent smooth nitration to give...

Surface oxidation of carbon nanofibres.

Chemistry (Weinheim an der Bergstrasse, Germany)

Ros TG, van Dillen AJ, Geus JW, Koningsberger DC.
PMID: 11891903
Chemistry. 2002 Mar 01;8(5):1151-62. doi: 10.1002/1521-3765(20020301)8:5<1151::aid-chem1151>3.0.co;2-#.

Carbon nanofibres of the fishbone and parallel types were surface-oxidised by several methods. The untreated and oxidised fibres were studied with infrared spectroscopy, thermogravimetric analysis and X-ray photoelectron spectroscopy (XPS). Oxidation in a mixture of concentrated nitric and sulfuric...

Atmospheric new particle formation enhanced by organic acids.

Science (New York, N.Y.)

Zhang R, Suh I, Zhao J, Zhang D, Fortner EC, Tie X, Molina LT, Molina MJ.
PMID: 15178797
Science. 2004 Jun 04;304(5676):1487-90. doi: 10.1126/science.1095139.

Atmospheric aerosols often contain a substantial fraction of organic matter, but the role of organic compounds in new nanometer-sized particle formation is highly uncertain. Laboratory experiments show that nucleation of sulfuric acid is considerably enhanced in the presence of...

Suicidal Carbon Monoxide Poisoning by Formic and Sulfuric Acids.

Academic forensic pathology

Kreutz K, Danielsen T, Quinton RA.
PMID: 32110257
Acad Forensic Pathol. 2019 Sep;9(3):217-224. doi: 10.1177/1925362119891703. Epub 2020 Jan 31.

In 1987, a case report was published in the German journal Archiv für Kriminologie describing an apparently novel method of suicide in which the decedent produced a lethal amount of carbon monoxide by mixing formic acid and sulfuric acid....

Stratospheric solar geoengineering without ozone loss.

Proceedings of the National Academy of Sciences of the United States of America

Keith DW, Weisenstein DK, Dykema JA, Keutsch FN.
PMID: 27956628
Proc Natl Acad Sci U S A. 2016 Dec 27;113(52):14910-14914. doi: 10.1073/pnas.1615572113. Epub 2016 Dec 12.

Injecting sulfate aerosol into the stratosphere, the most frequently analyzed proposal for solar geoengineering, may reduce some climate risks, but it would also entail new risks, including ozone loss and heating of the lower tropical stratosphere, which, in turn,...

Dissociation Constants of Perchloric and Sulfuric Acids in Aqueous Solution.

The journal of physical chemistry. B

Levanov AV, Isaikina OY, Gurbanova UD, Lunin VV.
PMID: 29771520
J Phys Chem B. 2018 Jun 14;122(23):6277-6286. doi: 10.1021/acs.jpcb.8b01947. Epub 2018 Jun 01.

The experimental dissociation constants of strong acids are notoriously ill-defined, and it is necessary to rely on theoretical methods for their evaluation. We present a methodology for the theoretical evaluation of the dissociation constants, and the values of K

Determination of the activity of hydrogen ions in dilute sulfuric acids by use of an ionic liquid salt bridge sandwiched by two hydrogen electrodes.

The activities of hydrogen ions in 20-200 μmol dm(-3) H(2)SO(4) solution were estimated by use of an ionic liquid salt bridge (ILSB), made of tributyl(2-methoxyethyl)phosphonium bis(pentafluoroethanesulfonyl)amide (TBMOEPC(2)C(2)N), sandwiched by two hydrogen electrodes. The experimental pH values (pH = -log...
