DIELECTRIC PROPERTIES OF POLY(VINYL ALCOHOL) HYDROGELS PREPARED BY FREEZING/THAWING TECHNIQUE (PROPIEDADES DIELÉCTRICAS DE HIDROGELES DE ALCOHOL POLIVINÍLICO OBTENIDOS POR LA TÉCNICA DE CONGELAMIENTO/ DESCONGELAMIENTO)
(Fondo Editorial EIA - Universidad EIA, 2013-09-27)
The dielectric behavior of poly(vinyl alcohol) –PVA– crosslinked hydrogels obtained by the repeated freezing/ thawing (F/T) technique have been investigated by dielectric relaxation spectroscopy (DRS) and differential ...
Compatibilization of poly(ethylene oxide)/poly(styrene) blends: Effect of the molecular weight of the compatibilizer
(Marcel Dekker, 2001)
The effect of the molecular weight and concentration of the compatibilizer maleic acid-alt-styrene copolymer (MAaS) on the compatibility behavior of incompatible poly(ethylene oxide)/poly(styrene) (PEO/PS) blends was studied ...
Non-isothermal Characterization of the Precipitation Hardening of a Cu-11Ni-19Zn-1Sn Alloy
(Springer, 2017)
The precipitation hardening of a Cu-11Ni-19Zn-1Sn alloy has been studied by means of
Differential Scanning Calorimetry (DSC), High-Resolution Transmission Electron Microscopy
(HRTEM), and hardness measurements. The ...
Maleic acid-alt-styrene copolymer as compatibilizer for poly(ethylene oxide)-poly(styrene) blends
(Marcel Dekker Inc, 2000)
Maleic acid-alt-styrene (MAaS) copolymer with number-average molecular weight M̄n = 2500 was used as a compatibilizer in blends of poly(ethylene oxide) (PEO) and poly(styrene) (PS). PEO with weight-average molecular weight ...
Effect of thermally reduced graphene oxides obtained at different temperatures on the barrier and mechanical properties of polypropylene/TRGO and polyamide-6/TRGO nanocomposites
(John Wiley and Sons Inc., 2019)
© 2018 Society of Plastics Engineers Polypropylene (PP) and polyamide-6 (PA6) nanocomposites containing thermally reduced graphene oxide (TRGO), obtained either at 600°C (TRGO 600 ) or 800°C (TRGO 800 ), were prepared by ...
Gamma-Irradiated Metallocenic Polyethylene and Ethylene-1-Hexene Copolymers
(Wiley, 2010)
The aim of this work is to present a detailed
study of the changes introduced by gamma radiation on
several metallocenic polyethylene copolymers. Therefore,
metallocenic polyethylene and copolymers with 3.3, 9.2,
and ...
Thermal stability and recrystallization of nanocrystalline Ti produced by cryogenic milling
(MINERALS METALS MATERIALS SOC, 2006-07)
The grain growth, thermal stability, and recrystallization behavior of a cryomilled Ti alloy with a grain size of about 21.2 nm were examined using differential scanning calorimetry, X-ray diffraction, and transmission ...
Synthesis and magnetic investigations on rare-earth-containing liquid crystals with large magnetic anisotropy
(AMER CHEMICAL SOC, 1996-04)
A new series of liquid-crystalline Schiff base lanthanide compounds of the general formula (L''H)(2)L''MX(2) was prepared (L''H = H2n+1CnOC6H3(OH)CHNCmH2m+1; n = 7, 12; m = 14, 18; M = La, Tb, Dy, Er, Nd, Ho, Eu, Pr, and ...
Nanoantioxidant–Based silica particles as flavonoid carrier for drug delivery applications
(MDPI, 2020)
Nanosystems used in pharmaceutical formulations have shown promising results in enhancing the administration of drugs of difficult formulations. In particular, porous silica nanoparticles have demonstrated excellent ...
Poly(N-phenylmaleimide-co-acrylic acid)-copper(II) and poly(N-phenylmaleimide-co-acrylic acid)-cobalt(II) complexes: Synthesis, characterization, and thermal behavior
(0887-624X, 2005-10-15)
The free-radical copolymerization of N-phenylmaleimide (N-PhMI) with acrylic acid was studied in the range of 25-75 mol % in the feed. The interactions of these copolymers with Cu(H) and Co(H) ions were investigated as a ...
