Composites made from lignocellulosics and thermoset polymers
(Gordon Breach Publishing, 2006-09-24)
Composites made from a stryrene/unsaturated polyester thermoset matrix and woodflours from different wood species have been prepared and tested. Pine (Pino Eliottis), eucaliptus (Eucaliptus Saligna) and marmelero (Ruprechia ...
Fluid-present deformation aids chemical modification of chromite: Insights from chromites from Golyamo Kamenyane, SE Bulgaria
Chemical signatures of chromitites are commonly used to track the evolution of the Earth's mantle. However, chemical modification during deformation may have important implications for the interpretation of chromites' ...
MODIFICATION AND CHEMICAL CHARACTERIZATION OF BARLEY STARCH.
Acetylation is a chemical modification for estherification, in which hydroxyl groups are replaced with acetyl groups that offers him major stability, changing the physicochemical and functional properties of the starches. ...
Deposition of copper sulfide on modified low-density polyethylene surface: morphology and electrical characterization
(Elsevier Science BvAmsterdamHolanda, 2002)
ACTIVATION OF HMDSO THIN FILMS WITH LOW PRESSURE ARGON PLASMA AND VACUUM ULTRAVIOLET RADIATION
(Plapiqui(uns-conicet)Bahia BlancaArgentina, 2012)
Edible films based on native and phosphated 80:20 waxy:normal corn starch
(Wiley Vch Verlag, 2015-01)
Edible films based on 80:20 waxy:normal corn starch were evaluated for their potential use in the food industry. Two types of film were prepared by the casting method: The first from native corn starch and the second from ...
Electronic structure of polythieno[3,4-b]-thiophene-co-benzodithiophene (PTB7) derivatives for organic solar cell applications
Among the new materials currently employed as electron donor element in active layers of organic solar cells (OSCs), PTB7 holds the best results. It has been extensively studied and now there is a search for new derivatives ...
Post-synthesis modification of hydrogels. Total and partial rupture of crosslinks: Formation of aldehyde groups and re-crosslinking of cleaved hydrogels
Post-synthesis modification of hydrogels is frequently used for chemical functionalization, immobilization of molecules or optimization of mechanical properties. In this work, novel gels were developed usinga divinyl ...
Chemical Modification of Palm Fibres Surface with Zirconium Oxychloride
(North Carolina State Univ Dept Wood & Paper Sci, 2013-01-01)
Chemical modification of natural fibres has been carried out using different methods for such purposes as reinforcement in polymer matrices and heavy metals adsorption. In this work, palm fibres were modified by zirconium ...
Theoretical evaluation of chemical substitutions along the main chain of poly(3-hexylthienylene-vinylene) for solar cell applications
In order to improve the efficiency of bulk-heterojunction organic solar cells, one can try to optimize the active layer through the use of new materials that provide improvements in the parameters that influence the final ...
