Many ionic surfactants with wide applications in personal-care and house-hold detergency show limited water solubility at lower temperatures (Krafft point). This drawback can be overcome by using mixed solutions, where the surfactant is incorporated micelles another surfactant, which soluble temperatures. The electrolytic conductivity for a binary mixture of anionic methyl ester sulfonates (MES...

Composting is an important waste management strategy, providing economical and environment-friendly approach to sanitizing stabilizing biosolids for land soil amendment. However, the resulting product can contain a large number of organic pollutants that may have adverse effects on ecosystem. This paper presents occurrence eight widely used (four linear alkylbenzene sulfonates (LAS C10-C13), no...

Human lactate dehydrogenase A plays an important role in the glucose metabolism of tumor cells and constitutes an attractive target for chemotherapy. Molecular fragments able to bind in the active site of this enzyme and form hydrogen bonds with the Arg168 guanidinium group, as well as additional interactions with the loop 96-111 in the closed conformation, have been identified by virtual scree...

Sodium dodecylbenzenesulfonate is one of a group of salts of alkylbenzene sulfonates used in cosmetics as surfactant-cleansing agents. Sodium dodecylbenzenesulfonate is soluble in water and partially soluble in alcohol, with dermal absorption dependent on pH. Dodecylbenzenesulfonate salts are not toxic in single-dose oral and dermal animal tests, and no systemic toxicities were observed in repe...

The crystal structure of the title compound, {[Er(2)(C(2)H(4)O(6)PS)(OH)(3)(H(2)O)]·H(2)O}(n), consists of two Er(3+) ions, one (C(2)H(4)O(6)PS)(3-) ion, three OH(-) ions, and two water mol-ecule. The Er(3+) ions form ErO(8) polyhedra., which are connected by μ- and μ(3)-O atoms. Thus, inorganic Er-O-Er layers of edge- and face-sharing polyhedra are observed. Whereas most often in metal phospho...

While Nature excels at performing selective modifications of complex polyfunctional molecules through the use of tailoring enzymes, synthetic chemistry has lagged behind in this regard. In prior work, we have applied a biomimetic approach to this problem, developing small peptides to achieve various group transfer reactions on polyol substrates with high enantio- or regioselectivity. The utilit...
