Kitchen in a can for people on the go

Article Abstract:

Convenience Heating Technologies (CHT) was formed in May 1999 to further develop existing technology for self-heating of foods and beverages according to representatives of J.C. Technologies Ltd. and Patir R&D Ltd. (both Israel) and a faculty member of the Hebrew University (Jerusalem). A patent is pending on its innovative system for self-propagating high-temperature synthesis with built-in safety features. Hikers, bikers, commuters, and military people can have hot by using the cans that heat themselves. The chemistry of the products, involving initiating a self-propagating high-temperature synthesis, oxidizing a consolidated powder mixture of aluminum and other metals by iron oxide, is discussed. a crucial intermediate stage has iron oxide and aluminum enriched with silicon. Moty Tenenboum and Reuven Tal, engineers, formed CHT and are behind the product. History of self-heating containers covered.

A simple process for removing chloroform from water

Article Abstract:

A novel, simple and effective two-step process for removing chloroform from water is discussed by two staff members of the chemical engineering department at the University General Requirement Unit at United Arab Emirates University. The process is adequate by public health standards for water that has a concentration of chloroform up to 6.7 g/L. An air curtain convection tank and a carbon bed system at the air exit are used. Physiological aspects of dermal exposure to chloroform are discussed.

Removing cyanide from waterways

Article Abstract:

An overview is presented on techniques for cleaning waterways from cyanide, a toxic byproduct of gold-ore mining. The advantages and disadvantages of using sulfur, sulfur compounds, iron salts, chlorine and aeration are discussed; the recommended solution is to mix air with polluted water, which detoxifies cyanide.
