Bioactive gelatin-siloxane hybrids as tissue engineering scaffold
Ca2+-containing porous gelatin-siloxane hybrids were prepared using sol-gel process, post-gelation soaking, and freeze-drying. The porosity and pore size of the hybrids could be well controlled by the freezing temperature ...
Cisplatin-loaded Au-Au2S noparticles for potential cancer therapy: Cytotoxicity, in vitro carcinogenicity, and cellular uptake
Cisplatin is one of the most effective cytotoxic agents against cancers. Its usage, however, is limited because of severe resistance and systemic toxicity. A formulation of cisplatin-loaded Au-Au2S nanoparticles (NPs) with ...
PEM fuel cells operated at 0% relative humidity in the temperature range of 23-120℃
(ELECTROCHIM ACTA, 2007-04-20)
Operation of a proton exchange membrane (PEM) fuel cell without external humidification (or 0% relative humidity, abbreviated as 0% RH) of the reactant gases is highly desirable, because it can eliminate the gas humidification ...
Ab initio study of the phase stability and mechanical properties of 5d transition metal nitrides MN2
(J ALLOY COMPD, 2009-03-20)
Recently platinum nitride and some other heavy transition metal nitrides have attracted great interest due to their remarkable properties. However, there are many discrepancies in the reported results. In this work, we ...
Coalescence process of monodispersed Co cluster assemblies
Cluster-cluster coalescence process of monodispersed Co clusters with mean diameter d = 8.5 and 13 nm deposited a plasma-gas-condensation-type cluster beam deposition system was investigated by in situ electrical conductivity ...
Single-crystal microtubes of a novel apatite-type compound, (Na25Bi25)(PO4)(3)(F,OH), with well-faceted hexagonal cross sections
(ROYAL SOC CHEMISTRY, 2009)
A novel apatite-type compound, (Na2.5Bi2.5)(PO4)(3)(F,OH), NBPF, in the form of single-crystal microtubes with well-faceted, hexagonal morphologies in both exterior and interior surfaces, has been synthesized under ...
Seebeck coefficient of nanostructured phosphorus-alloyed bismuth telluride thick films
(J ALLOY COMPD, 2009-03-05)
Nanostructured phosphorous-alloyed Bi(2)Te(3) thick films have been prepared by electrochemical deposition. The average grain size of the films was calculated to be 14-26nm based on Scherrer's equation. The effect of P on ...
Fatigue behavior of ferroelectric ceramics under mechanically-electrically coupled cyclic loads
The fatigue behavior of commercial ferroelectric ceramics PZT-5 was studied by carrying out four-point bending experiments for the poled and unpoled samples. Two types of mechanical loads (constant and cyclic) coupled with ...
Characterization of regenerated cellulose membranes hydrolyzed from cellulose acetate
A series of cellulose acetate membranes were prepared by using formamide as additive, and then were hydrolyzed in 4 wt% aqueous NaOH solution for 8 h to obtain regenerated cellulose membranes. The dependence of degree of ...
