Biobased protective agent from plant cell culture for wood-based materials
Conventional wood preservatives often contain substances that are harmful to the environment and to health. With the new biocide regulation of 21-05-21, the approval conditions for these substances have been tightened. As a result some

Problem: EDTA and similiar chelating agents are commonly used chemicals capable of chelating metals. They can increase bioavailability of heavy and radioactive metals in the environment, restrict the availability of essential metals or contribute to
Read moreNew kinds of cellulose-based sorbents
Macroporous bead cellulose is an excellent matrix for sophisticated applications in many diverse areas including analytical chemistry, enzyme engineering or biotechnology, where its hydrophilic nature, high porosity and mechanical as well as chemical resistance are

Problem: Chronic surface wound infections such as venous or diabetic ulcers are a very common disease affecting 1-2% of the population with a marked increase in the incidence of seniors with diabetes and circulatory problems
Read moreNanoparticulate reactive sorbents
These so-called reactive sorbents are able not only to retain various toxic substances on their surface, but also to decompose them to non-toxic or less-toxic residua. The reactive sorbents are effective in the decomposition of
