The polymer-based solid electrolyte is coated with sulfonic acid
ligands to conduct positive charge or amino functional groups to conduct negative ions.
Three different acid dyes were synthesized by employing substituted aryl amines and aminohydroxy-naphthalene sulfonic acid
as diazo and coupling components, respectively.
"While the polymer with lower concentrations of the sulfonic acid
groups had no practical effect against human adenovirus, it could destroy 99.997 per cent of that virus at higher sulfonic acid
"When microbes come into contact with the polymer, water on the surface of the microbes interacts with the sulfonic acid
functional groups in the polymer - creating an acidic solution that quickly kills the bacteria," says Reza Ghiladi, an associate professor of chemistry at NC State and co-corresponding author of the paper.
Median serum concentrations of perfluorohexane sulfonic acid
(PFHxS, 2.1 [micro]g/L) and linear perfluorooctane sulfonic acid
(n-PFOS, 5.5 [micro]g/L) were markedly higher than were those in NHANES participants (1.2 [micro]g/L and 3.2 [micro]g/L, respectively).
and the conventional ion-exchange resins are extensively used in several industrial applications such as recovery and creation of metals, industrial wastewater treatment.
According to the complaint, various manufacturers and sellers created, advertised, and sold aqueous film-forming foam products containing chemicals known as perfluorooctane sulfonic acid
, or PFOS, and perfluorooctanoic acid, or PFOA.
In the infrared spectrum of SPS, the characteristic absorption peak of sulfonic acid
group appeared at 1183 [cm.sup.-1], which indicated that the reaction of concentrated sulfuric acid with polystyrene resulted in sulfonated polystyrene.
The method entails applying a formulation comprising one or more hydroxide-containing agents and one or more active agents selected from the group consisting of maleic acid, acrylic acid, methyl acrylic acid and vinyl sulfonic acid
, and simple salts thereof to the hair; and reshaping the hair.
These include doping with organic acids, such as dodecyl benzene sulfonic acid
(DBSA)  or camphor sulfonic acid
Tetrabromophenol blue has three parts, which are sulfonic acid
, 1,2,3,4-tetrabromobenzene, and 2,6-dibromophenol.
As a first step, AGC started sales of new fluorinated sulfonic acid
ion exchange membranes 'FORBLUE S-series' on November 6.
