Ohmic heating for efficient green synthesis

22 Feb 2013

With environmental issues increasingly in the news, overcoming the challenges associated with greener chemistry has become a major focus of scientific research. To this aim, Portuguese scientists have developed a new ohmic-heating reactor for organic syntheses ‘on water,’ ie chemistry using an aqueous suspension of the reactants.

With ohmic heating the reaction medium itself serves as an electrical resistor, and is heated by passing electricity through it. Internal energy transformation occurs, from electrical to thermal energy, thanks to ion movement and friction within the reaction medium. Since the heating process depends on the resistivity of the medium, the exact conditions vary from reaction to reaction.

Environmentally friendly alternative to toxic heavy metals in paint

24 Jan 2013

Austrian scientists have shown that an environmentally friendly enzyme, laccase, can be used to replace toxic drying agents in paint.

Currently, water-based paints contain heavy metals that dry the alkyd (polyester) resin films that are used as binding agents by catalysing the oxidative cross-linking of unsaturated fatty acid moieties in the films. Heavy metals are often toxic, and the commonly used cobalt-based catalysts have recently proved to be carcinogenic, and so alternative materials are being sought.

An enzyme system could be an environmentally friendly alternative to toxic heavy metal drying agents in paints

Enrique Herrero Acero at the Austrian Centre of Industrial Biotechnology, Graz, and colleagues, decided to replace the heavy metal catalysts with a laccase enzyme–mediator-based, non-toxic biocatalyst. Laccases, found in fungi, bacteria and plants, can catalyse the oxidation of mainly phenolic substances, and are already used in other fields, including the food, pulp and paper, and textile industries.
