The composition of waterproof barrier creams? ingredients and their barrier properties

The composition of waterproof barrier creams? ingredients and their barrier properties KURPIEWSKAJ., LIWKOWICZ J., PADLEWSKA K. Please cite as: CHEMIK 2012, 66, 9, 991-996 Hands? skin protection is important due to growing number of cases of contact dermatitis, caused by contact with harmful or irritating substances. The best protection provide gloves, but when the use of them is not recommended skin protection measure can be applied, on condition that it has apropriate barrier properties. Laboratory tests for assessing effectiveness of barrier hydrophobic preparations confirmed the...

Catalytic conversion of furfural towards fuel biocomponents

Catalytic conversion of furfural towards fuel biocomponents MALINOWSKI A., WARDZIŃSKA D. Please cite as: CHEMIK 2012, 66, 9, 982-990 This article presents a review of some furan compounds, derived from biomass, having a high potential for the synthesis of valuable biochemicals. In this paper we mainly focused on the catalytic preparation methods and properties of furfural derivatives which can be used as fuel bio-components or biofuel itself. Keywords: furfural, biofuels, catalytic conversion Read more:

Genetically modified plants - from the laboratory to practical application in European agriculture. Part II LINKIEWICZ A., DĄBROWSKI Z.T., SOWA S. Please cite as: CHEMIK 2012, 66, 9, 966-981 The release of genetically modified plants into the environment is not only a subject of legal regulations, but also an important subject matter of the scientific and social debate. The article presents rules forming the basis of the risk assessment related to use of GMOs. It quotes the results of numerous studies concerning the impact...

Bioliquids ? liquid fuels. Validation of methods for denoting quality parameters based on the example of waste glycerine

Bioliquids ? liquid fuels. Validation of methods for denoting quality parameters based on the example of waste glycerine MUZYKA R., PLIS A., TOPOLNICKA T. Please cite as: CHEMIK 2012, 66, 9, 954-965 Due to the increasing share of biocomponents in liquid fuels used in transportation, an increase has been noted in the amount of bioliquids ? waste glycerine which may be used in the production of electric energy, heat or coolness ? together with the dynamic development of the market of producers of fatty...

Study on dispersion stability and coating properties from water-thinnable acrylic compositions

Study on dispersion stability and coating properties from water-thinnable acrylic compositions ZALEWSKA A., KOWALIK J. Please cite as: CHEMIK 2012, 66, 9, 943-953 Water-thinnable paints and coatings containing non-ionic surfactant (a product of Chemical Manufactures in Brzeg Dolny) and organic thickening agent (product of Brenntag Poland) were tested. The sedimentation experiment was a basic test used to determine the stability of water dispersion. The obtained coating compositions were applied by brush on steel, glass and wooden plates and were cured in a temperature of 20°C....

Glutathione: methods of sample preparation for chromatography and capillary electrophoresis

Glutathione: methods of sample preparation for chromatography and capillary electrophoresis BŁOŃSKA-SIKORA E., OSZCZUDŁOWSKI J., WITKIEWICZ Z., WIDEŁ D. Please cite as: CHEMIK 2012, 66, 9, 929-942 Reduced form of glutathione is one of the most important antioxidants, which is found in human body. Deficiency of this compound can often lead to serious disorders. It plays a central role in immunity modulation, detoxification capacities and regulation of activity of another peptides and enzymes. In every live organism it acts as a sensitive rate of susceptibility to...

Rapid growth approaches from nano-Mg(OH)2 to bulk materials and their application in the environment

Rapid growth approaches from nano-Mg(OH)2 to bulk materials and their application in the environment LIU W., HUANG F., LIN Z. Please cite as: CHEMIK 2012, 66, 9, 919-928 There is a strong demand for the investigations on the detoxification of the nano-wastes or recycling of the loaded nanoadsorbents. This article reviews the studies of our group in this field. The treatment of Cr(VI) loaded nano-Mg(OH)2 introduces a new strategy for nano-waste disposal. The nano-wastes were converted into a nontoxic bulk material and a concentrated...
