Chementator: This composite combines the unique properties of two new forms of carbon  

Of all known materials, carbon nanotubes (CNTs) have the highest thermal conductivity and mechanical strength as well as the ability to withstand the highest electric-current density, making them an attractive material for electric wiring, heat dissipation, field electron emission, and…

Chementator: Halogenated activated carbon reduces mercury emissions from a coal-fired plant  

In its first full-scale test on a coal-fired power plant, halogenated activated carbon (AC) made by ADA-ES, Inc. (Littleton, Colo.; edlinks.chemengonline.com/7371-537) has reduced mercury emissions by more than 90%. The significance of the results is that the plant burns western…

Chementator: A platinum-free catalytic converter    

Nippon Steel Materials Co., Ltd. (NSM; Tokyo, Japan; edlinks.chemengonline.com/7371-538) has developed a new catalyst for combustion engines that contains 70% less precious metals than conventional catalytic converters. The catalyst is expected to not only lead to lower costs, but also…

Chementator: A new Mg2Si-production process promises to advance thermoelectric devices    

The Seebeck effect — the direct conversion of a temperature difference to electricity — is responsible for the operation of thermocouples. But taking advantage of this phenomenon to make electricity from waste heat in so-called thermoelectric (TE) devices has been…

Chementator: A portable analyzer for toxicity in humans    

The standard way to test for toxicity in individuals who have been exposed to heavy metals is to take a blood sample and analyze it in the laboratory by plasma mass spectrometry, an expensive and time-consuming procedure. Now, a portable…

Chementator: A promising nanosieve for dehydrating solvents and biofuels  

Although nanoporous silica membranes are promising systems for the molecular separation of gases and liquids, they lack microstructural stability in the presence of water at temperatures as low as 60°C. Prolonged exposure to water causes hydrolysis, resulting in the formation…
