Protecting wood with citrus

14.10.2002


One of the most widespread ways to protect wood from organisms’ attacks is to use chemicals. However, due to the risks its usage involves (toxic for the user, pollution of the environment…), the interest to obtain a more effective but non-polluting protector has increased.



Nowadays, the research of active matter with biocide effects has become one of the most interesting research lines to find new pesticides.

Objectives


The aim of the project the Basque Research Centre CIDEMCO is developing is mainly to assess the biocide potential of citrus waste derived from agri-foodstuffs sector may have. That way it will be able to know if that waste may be useful to protect wood from insects and fungus.

Therefore, the project has two objectives: on the one side, developing ways that allow the re-utilisation of that waste; as waste itself or as raw material for fungicides and insecticides. On the other side, knowing which citrus type or part of citrus (skin, pulp, seeds) and which extraction method will be the most appropriate to obtain those biocides.

New wood protectors

First of all, the research of new natural wood protectors implies a bibliographic search of natural substances with biocide potential, for example, vegetal extracts derived from citrus. Then, several extracts will be done. Once short biological tests are done, those extracts less effective against xylophagous organisms will be discarded. Once the most effective natural substances are identified, following the actual European regulations on the evaluation of wood protectors, biological tests will be carried out with the most representative xylophagous organisms, that is, fungus and insects.

The results will allow measuring the application each analysed active material has as wood protector.

The results of the research give the opportunity to continue with this research line. That will allow the measure many other aspects such as toxic and environmental properties, the behaviour of those substances on wood (stability of biocide through the years, facility to clean, penetration…) and viability of production cost and commercialisation.

Im Focus: Manipulating Electron Spins Without Loss of Information

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.

For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...

Im Focus: The proton precisely weighted

What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.

To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
