Effect of ball milling on structural and physicochemical characteristics of cassava and Peruvian carrot starches
(2013-03-01)
Peruvian carrot and cassava starches were ground in a ball mill for 4, 8, 16, and 32 h and their structural and physicochemical characteristics were determined. Results obtained from HPAEC-PAD, GPC, and amylose content ...
Influence of current density on crystalline structure and magnetic properties of electrodeposited Co-rich CoNiW alloys
(2013-08-15)
The influence of current density, at the interval 5-100 mA cm-2, on the structural and magnetic properties of electrodeposited (Co 100-xNix)100-yWy alloys (x = 23-33.5 at. % Ni, y = 1.7-7.3 at. % W) was studied from a ...
Structural modifications in stretch-induced crystallization in PVDF films as measured by small-angle X-ray scattering
(Wiley-Blackwell, 2012-07-05)
The nanostructure of stretched and nonstretched PVDF samples was studied by small-angle X-ray scattering (SAXS). The crystallinity of the samples was determined by wide-angle X-ray diffraction (WAXD) and differential ...
Structural characterization and in vivo evaluation of retinyl palmitate in non-ionic lamellar liquid crystalline system
(Elsevier B.V., 2011-07-01)
Carrier systems for lipophilic drugs, such as the liquid crystalline systems (LCS) have been extensively studied to improve effect and selectivity. Retinyl palmitate (RP) is widely used in pharmaceutical and cosmetics ...
Well productivity controlling factors in crystalline terrains of southeastern Brazil
(Springer, 2007-05-01)
Over the last decades, increasing water demands have fostered research to obtain high well yields in crystalline terrains where, besides the intrinsic properties of rocks, the groundwater flow depends on several factors. ...
Thermal decomposition of crystalline Ni-II-Cr-III layered double hydroxide: A structural study of the segregation process
(Amer Chemical Soc, 2005-05-26)
A structural study of the thermal evolution of Ni0.69Cr0.31(OH)(2)(CO3)(0.155)(.)nH(2)O into NiO and tetragonal NiCr2O4 is reported. The characteristic structural parameters of the two coexisting crystalline phases, as ...
Giant Chemo-Resistance of SnO disk-like structures
(2013-07-03)
Single crystalline SnO micro-disks, synthesized by a carbothermal reduction process, exhibited a nearly 1000-fold increase in resistance upon exposure to 100 ppm of NO2 without addition of catalysts or dopants nor the ...
Luminescence in semi-crystalline zirconium titanate doped with lanthanum
(Elsevier B.V., 2006-10-25)
This paper aims to describe the synthesis of the semi-crystalline and crystalline powder of lanthanum doped with zirconium titanate (65/35), LZT through Pechini method. The analysis done by Raman demonstrated that ...
Influence of ethanol and glycerol concentration over functional and structural properties of zein-oleic acid films
(2013-11-15)
This study was performed in order to determine the effect of the addition of different concentrations of glycerol and ethanol over functional and structural properties of zein-oleic acid films. Films were prepared from ...
Crystal Structures of Xanthomonas Small Heat Shock Protein Provide a Structural Basis for an Active Molecular Chaperone Oligomer
(Academic Press Ltd Elsevier B.V. Ltd, 2011-04-22)
Small heat shock proteins (sHsps) are ubiquitous low-molecular-weight chaperones that prevent protein aggregation under cellular stresses. sHsps contain a structurally conserved alpha-crystallin domain (ACD) of about 100 ...
