Hydrophobization of concrete and aerated concrete by impregnation with calcium polysulfide [PDF]
Нанотехнологии в строительствеIntroduction. A method for protecting concrete and aerated concrete by treatment with a calcium polysulfide-based solution is considered. The solution penetrates into the pores of the materials and, after drying, forms a water-repellent nanoscale layer,

Applying a Hydrophilic Modified Hollow Fiber Membrane to Reduce Fouling in Artificial Lungs
Separations, 2021 Membranes for use in high gas exchange lung applications are riddled with fouling. The goal of this research is to create a membrane that can function in an artificial lung until the actual lung becomes available for the patient.

Polysulfid-Radikalionen in Aceton / Polysulfide Radical Ions in Acetone
Zeitschrift für Naturforschung B, 1987 Abstract The formation of sulfur radical ions S 3 ~ and S 4 " in the blue and violet solutions of potassium sulfide and sulfur in acetone on adding 18C6 crown ether has been demonstrated by spectrophotometric titra-tion under anaerobic conditions. Neither the colour nor the spectra of the solutions point at S 2 ~.

Human hair keratin responds to oxidative stress via reactive sulfur and supersulfides
Advances in Redox ResearchKeratin is a central component of human hair proteins, which explicitly possesses many cysteine residues (Cys-SH). For a long time, these Cys-SH residues were believed to contribute to human hair strength by forming intra- and inter-molecular disulfide ...
