MODIFICATION AND CHEMICAL CHARACTERIZATION OF BARLEY STARCH.
(2013-02-22)
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. ...
Fluid-present deformation aids chemical modification of chromite: Insights from chromites from Golyamo Kamenyane, SE Bulgaria
(Elsevier, 2015)
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' ...
Surface modifications of Volcanic Glasses (Perlites) by water vapor
(Planta Piloto de Ingeniería Química, 2003-12)
Hydrothermal treatments on expanded volcanic glasses (perlites) were studied. The main objective of this paper is to obtain an activated surface able to interact with specific chemical substances. The above mentioned ...
Nano-modification of Si-wafer surfaces using low-cost ambient air diffuse plasma
(2015-01-01)
In this paper, we demonstrated the cleaning and nano-oxidation of Si-wafer surfaces by atmospheric pressure plasma, generated in ambient air using diffuse coplanar surface barrier discharge. Plasma treatment for one second ...
Deposition of copper sulfide on modified low-density polyethylene surface: morphology and electrical characterization
(Elsevier Science BvAmsterdamHolanda, 2002)
Physical and chemical changes in juvenile and mature wood of shizolobium parahyba caused by thermal modification
(2020-01-01)
In the Brazilian Atlantic Forest, the pioneer species Schizolobium parahyba, known as guapuruvu, is a fastgrowing tree with potential for ecological restoration in forest management projects. However, an undesirable feature ...
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
(2016-06-01)
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 ...
Surface modification of polymeric materials by cold atmospheric plasma jet
(Elsevier B.V., 2014-09-30)
In this work we report the surface modification of different engineering polymers, such as, polyethylene terephthalate (PET), polyethylene (PE) and polypropylene (PP) by an atmospheric pressure plasma jet (APPJ). It was ...
