Hydrogen Peroxide Solution

The corrosion behavior of titanium in hydrogen peroxide solutions was studied by measuring the titanium ions concentration using spectrophotometer. The influence of additives (K+ ， Ca2+ ，Na+ ，Mg2+ ，Cl- ，HPO4 2-, H2PO4 - ) on the corrosion behavior of titanium was examined. The results indicated that Ca2+ exhibited the highest inhibition to the titanium corrosion in hydrogen peroxide solutions, while HPO4 2- behaved as an accelerator to the corrosion. It was suggested that the Ca2+ was absorbed on the titanium surface to form a thin film of CaTiO3 or CaO2, and consequently, inhibited the corrosion of titanium. The acceleration of the titanium corrosion in the present of HPO4 2- was caused probably by the increased defect of surface oxide films after absorption of HPO4 2- ions.

The mechanism of the enzymatic iodination process of diethylmaleate and diethylfumarate (which present no miscibility with water) in the presence of lactoperoxidase, both in diluted hydrogen peroxide solution and in a generating system of hydrogen peroxide using ammonium and calcium iodides as halide sources in disperse system (after an ultrasonic pretreatment) was studied. The obtained sole product (diethyl-2, 3-diiodosuccinate) after the enzymatic iodination process was directly hydrolyzed to a tartaric acid present in an optically inactive form. The mechanism of obtaining the intermediate and final products and respectively, the existence of both D, L-tartaric acid and meso-tartaric acids (as lithium bitartrates) were also investigated.

Tmah Solution

Since Tetramethylammonium Hydroxide (TMAH) became widely used as a silicon etchant, e.g. the dummy gate removal for gate-last approach (RMG) [1, or Si fin formation on FinFET [, some careful preparations and optimizations have required implementation. These adaptations have involved not only chemical-related issues, but also hardware-related in order to satisfy the necessary process performance.

Venous Gas Embolism

Gas embolism to the portal venous system is a well-recognized radiographic sign in infants with necrotizing enterocolitis. It also has been seen after colonic irrigation with hydrogen peroxide solution.1,2 We present what we believe is the first reported patient with radiographic evidence of portal venous gas embolism after ingestion of hydrogen peroxide solution. This finding is important because gas embolism to the portal venous system after colonic irrigation with hydrogen peroxide has been associated with gangrenous and perforated bowel.1,2 CASE REPORT A 2-year-old boy ingested an unknown amount of 3% hydrogen peroxide solution. The child was found with foam around his mouth.
