Protective Properties of a Microstructure Composed of Barrier Nanostructured Organics and SiO Layers Deposited on a Polymer Matrix.

The SiO barrier nanocoatings have been prepared on selected polymer matrices to increase their resistance against permeation of toxic substances. The aim has been to find out whether the method of vacuum plasma deposition of SiO barrier nanocoatings on a polyethylene terephthalate (PET) foil used by Aluminium Company of Canada (ALCAN) company (ALCAN Packaging Kreuzlingen AG (SA/Ltd., Kreuzlingen, Switzerland) within the production of CERAMIS packaging materials with barrier properties can also be used to increase the resistance of foils from other polymers against the permeation of organic solvents and other toxic liquids.

Preparation of Filtration Sorptive Materials from Nanofibers, Bicofibers, and Textile Adsorbents without Binders Employment.

The article deals with the preparation and possibilities of using combined filtration sorption systems usable for the construction of folded filters or respirators. The studied materials are made of several structural layers-a filter membrane made of polymeric nanofibers, an adsorbent containing active carbon or porous silicon dioxide nanofibers, and a supporting or cover nonwoven bicomponent fabric. The layers are connected only by pressure at an elevated temperature without the use of binders, according to utility model PUV 31 375.

Phosphopeptide enrichment with inorganic nanofibers prepared by forcespinning technology.

Efficient selective sample enrichment is often a key procedure in protocols for analyses of complex samples. This applies not only to trace sample components but also to species with weak detection response. For example enrichment of phosphopeptides using selective affinity techniques prior to mass spectrometry analysis is necessary to increase detection sensitivity of phosphopeptides from highly complex peptide mixtures.
