Pneumothorax following inhalation of caustic soda fumes.

new family home. He accidentally leant over the bucket and inhaled the fumes produced by the solution. Five minutes after the inhalation, he developed persistent pleuritic, right-sided chest pain and breathlessness. There was no personal or family history of pulmonary disease, and he had never smoked. Physical abnormalities were confined to the chest. He had a respiratory rate of 30 a minute an...

Regeneration of Caustic Soda Etch Solutions for Aluminum

A system for the regeneratlon of caustic soda solutlons used In etching aluminum Invokes the hydrolysis of sodium aluminate to llberate free sodium hydroxide and produce a dry, crystalllne hydrated alumlna byproduct. The system has been used extenslvely In Japan, and, by adjusting process parameters, can be adapted to North American practice. By otlllting the system in a typical plant, soild ai...

Electrocatalytic Activity of Organically Functionalized Silver Nanoparticles in Oxygen Reduction

Silver nanoparticles capped by a variety of organic ligands (i.e., 1-hexanethiol, 1-octyne, and 4-trifluoromethylphenyl fragments) were synthesized by a chemical reduction route, with the resulting nanoparticles denoted as AgSC6, AgHC8, and AgPhCF3, respectively. The nanoparticle structures were characterized by using a variety of techniques including NMR, UV-vis, infrared, thermogravimetric an...
