MODIFICATION OF POLYACRYLONITRILE-BASED CARBON FIBER WITH CARBON NANOTUBES TREATED BY CHITOSAN DERIVATIVES
(ACTA POLYM SIN, 2011-10-20)
A polyacrylonitrile-based carbon fiber modified with multi-walled carbon nanotubes (MWNTs) was prepared in this paper. Three chitosan derivatives, phthaloyl chitosan (PhthCS), naphthoyl chitosan and carboxymethyl chitosan, ...
(Ga(071)B(029))PO(4) with a high-cristobalite-type structure refined from powder data
Gallium boron phosphate, (Ga0.71B0.29)PO4, was synthesized by a high-temperature solid-state reaction method. The crystal structure is isostructural with the tetragonal high-cristobalite structure with space group P (4) ...
First-principles investigation of mechanical and thermodynamic properties of the rare earth intermetallic YbAl3 under pressure
First-principles calculations are used to study the elastic, electronic, vibrational and thermodynamic properties of the rare earth intermetallic YbAl3 under pressure up to 41.9 GPa. Using the total energy calculations ...
Preparation of TiO2 loaded with crystalline nano Ag by a one-step low-temperature hydrothermal method
(J MATER CHEM, 2012)
TiO2 loaded with crystalline nano silver (c-Ag/TiO2) was successfully synthesized by a one-step low-temperature hydrothermal method in aqueous solution using tetra-n-butyl titanate and AgNO3 as precursors. The structure ...
Experimental and theoretical study of silicon-doped Sb2Te3 thin films: Structure and phase stability
(APPL SURF SCI, 2011-03-01)
The influence of Si in Sb2Te3 on structure and phase stability was studied by experiments and ab initio calculations. With the increase of Si content in Sb2Te3 samples, the crystallization temperature increases and the ...
BN coatings prepared by low pressure chemical vapor deposition using boron trichloride-ammonia-hydrogen-argon mixture gases
(SURF COAT TECH, 2010-05-15)
Boron nitride (BN) coatings were prepared by low pressure chemical vapor deposition (LPCVD) using boron trichloride (BCl(3))-ammonia (NH(3))-hydrogen (H(2))-argon (Ar) mixture gases. Thermodynamic analysis indicated that ...
Preparation and characterization of cellulose-coated chitosan beads with improved strength and acid resistivity
(J APPL POLYM SCI, 2012-10-25)
A new chitosan bead was successfully prepared by simply dropping acidic chitosan solution into 0.5 wt % alkaline cellulose solution. The X-ray photoelectron spectroscopy analysis and the scanning electron microscope ...
First-principles investigation on the phase stability and chemical bonding of mInSbnInTe phase-change random alloys
(SOLID STATE COMMUN, 2010-08)
The phase stability and bond character of mInSb.nInTe (m = 1, n = 2 or 3) phase-change materials have been investigated by means of ab initio calculations. The results show that In(3)SbTe(2) (IST312) is a metastable phase ...
Self-assembly of natural tripeptide glutathione triggered by graphene oxide
(SOFT MATTER, 2012)
A facile and straightforward approach for the preparation of graphene oxide-triggered self-assembly of natural tripeptide glutathione gels with different structures is reported. The morphologies of glutathione/graphene ...
