Precipitation and Solubility of Calcium Hydrogenurate Hexahydrate
Solid phases formed in the quaternary system: uric acid-calcium hydroxide -hydrochloric acid-water aged for 2 months at 310 K were studied to determine conditions for calcium hydrogenurate hexahydrate, Ca(C5H3N4O)2 · 6H2O precipitation. The precipitates were identified by chemical and thermogravimetric analyses, x-ray powder diffraction, infrared spectroscopy, light microscopy, and scanning ele...
متن کاملCadmium sulfite hexahydrate revisited
The present structural revision of the title compound, tetra-cadmium tetra-sulfite hexa-hydrate, [Cd(4)(SO(3))(4)(H(2)O)(5)]·H(2)O, is a low-temperature upgrade (T = 100 K and R = 0.017) of the original room-temperature structure reported by Kiers & Vos [Cryst. Struct. Commun. (1978). 7, 399-403; T = 293 K and R = 0.080). The compound is a three-dimensional polymer with four independent cadmium...
متن کاملAxillary hyperhidrosis - topical treatment with aluminium chloride hexahydrate.
Forty-two patients with axillary hyperhidrosis on the waiting list for surgery were treated with topical saturated solution of aluminium chloride hexahydrate in absolute alcohol. There have been 7 failures. Three patients were unable to cope with the treatment and 4 more experienced severe local irritation or soreness; these 4 were submitted to local surgery. This is a simple and effective trea...
متن کاملEfficacy of 20% Aluminium Chloride Hexahydrate in the treatment of multiple eccrine Hidrocystoma
Background: Eccrine hydrocystomas are essentially eccrine sweat gland retention cyst located in the dermis that clinically presents as small translucent cystic swelling. Objective: This study was designed to evaluate the efficacy and safety of 20% aluminum chloride hexahydrate in absolute alcohol in the treatment of eccrine hydrocystoma. Patients and Methods: In a randomized, double-blind...
متن کاملTheoretical investigations of the optical spectra and EPR parameters for VO in Zinc Potassium Phosphate Hexahydrate
The optical spectrum band positions and EPR parameters (g factors g//, g⊥ and hyperfine structure constants A// and A⊥) for VO 2+ ions in zinc potassium phosphate hexahydrate are theoretically studied from the complete diagonalization (of energy matrix) method (CDM). In the calculation, the contributions to the EPR parameters from the s-and p-orbitals as well as the spin-orbit coupling coeffici...
