Hydrogels: An Effective Tool to Improve Nitrogen Use Efficiency in Crops
(Springer, 2019)
Hydrogels are hydrophilic polymeric materials with three-dimensional(3D) network structures physic and/or chemically crosslinked. They can absorb large amounts of water or aqueous solutions for a short period of time. When ...
Argon ion implantation inducing modifications in the properties of benzene plasma polymers
(Elsevier B.V., 2002-05-01)
Benzene plasma polymer films were bombarded with Ar ions by plasma immersion ion implantation. The treatments were performed using argon pressure of 3 Pa and 70 W of applied power. The substrate holder was polarized with ...
Influence of cerium (IV) ions on the mechanism of organosilane polymerization and on the improvement of its barrier properties
(Pergamon-Elsevier B.V. Ltd, 2009-03-30)
In this work, the effect of cerium (IV) ammonium nitrate (CAN) addition on the polymerization of bis-[triethoxysilyl]ethane (BTSE) film applied on carbon steel was studied. The electrochemical characterization of the films ...
SAXS study of gelation, aging and drying of silica-polypropyleneglycol hybrid materials
(Japan J Applied Physics, 1999-01-01)
New silica-polypropyleneglycol ormosils (organically modified silicates) with covalent bends between the organic (polymer) and inorganic (silica) phases have been prepared by the sol-gel process. Their structural evolution ...
Modification of polyester composites by the use of cellulosic fibers and butyl acrylate monomer
(1994)
In this work, chemically treated cellulosic fibers are used to reinforce polyester resin crosslinked with either styrene or butyl acrylate monomer. Fiber resin affinity is enhanced confering to the composite considerably ...
EFFECT OF STRUCTURAL CHARACTERISTICS OF MODIFIED WAXY CORN STARCHES ON RHEOLOGICAL PROPERTIES, FILM-FORMING SOLUTIONS, AND ON WATER VAPOR PERMEABILITY, SOLUBILITY, AND OPACITY OF FILMS.
(2013-02-22)
Waxy corn starch (amylopectin) and three of its chemical derivatives: acetylated cross-linked (ACLS), oxidized (OS), and octenyl-succinylated (OSA), were used together with additives such as Tween 80, sorbitol, and beeswax ...
Obtención y caracterización estructural de compositos a partir de sub-productos de agave y coco
(2011-11-25)
Microstructured and moldable materials were designed, obtained and
characterized as composites from by-products of Cocus nucifera L. and Agave
angustifolia Haw. Powders and leached sustances with crosslinking agents ...

Plasma polymer deposition of neutral agent carvacrol on a metallic surface by using dielectric barrier discharge plasma in ambient air
(2020-01-01)
This experiment was conducted by newly designed home-made planar type DBD plasma generator in ambient, with industrial argon as the primary plasma-forming and a carrier gas of monomer. Natural agent Carvacrol monomer was ...
