Wood Polymer Composite Based on a Styrene and Triethoxy(Vinylphenethyl)silane

Today obtaining environmentally friendly wood composite materials is one of the main tasks. The urea-, phenol-, and melamine-formaldehyde resins used today are harmful to the human body and have a long-lasting effect. Therefore, replacing these and other resins with safe binders is one of the major problems.

Мethods of forensic examination of microparticless of platinum

In the article on an example from expert practice the considered methods of forensic еxamination of microparticless of platinum. An exposure and separation of microparticless of platinum from mechanical mixture of other metallic microparticless conducted with the use of methods of optical microscopy, magnetic separation and chemical dissolution of metals.
For the decision of diagnostic and identification questions the method of emission spectrology was used.
