Kinetic study of the hydrogen oxidation reaction on sub-stoichiometric titanium oxide-supported platinum electrocatalyst in acid solution
(Elsevier, 2009)
The kinetics and mechanism of the hydrogen oxidation reaction were studied in 0.5 mol dm-3 HClO4 solution on an electrode based on titanium oxide with Magneli phase structure-supported platinum electrocatalyst applied on ...
Synthesis and characterization of thermoplastic poly(ester-siloxane)s
(Wiley-Blackwell, 2001)
Two series of thermoplastic poly (ester-siloxane)s, based on poly(dimethylsiloxane) (PDMS) as the soft segment and poly(butylene terephthalate) as the hard segment, were synthesized by two-step catalyzed transesterification ...
Semi-interpenetrating polymer networks composed of poly(N-isopropyl acrylamide) and polyacrylamide hydrogels
(John Wiley and Sons Inc., 2004)
Three series of semi-interpenetrating polymer networks, baaed on crosslinked poly(N-isopropyl acrylamide) (PNIPA) and 1 wt % nonionic or ionic (cationic and anionic) linear polyacrylamide (PAAm), were synthesized to improve ...
A kinetic study of the thermal degradation of 3-methylaminopropylamine inside AlPO4-21
(Springer, Dordrecht, 2007)
Kinetics of the thermal decomposition of 3-methylaminopropylamine which was used as a structure-directing agent in the synthesis of AlPO4-21 has been studied under isothermal and non-isothermal conditions. The decomposition ...
Tunneling times in complex potentials
(Elsevier, Amsterdam, 2008)
Tunneling times in absorptive media, described by complex potentials, are investigated. A general expression relating relevant tunneling times is extended by introducing a new term tau(a). For both single Dirac delta ...
Influence of nonparabolicity on tunneling times in semiconductor structures
(Elsevier Science Bv, Amsterdam, 2007)
Tunneling of a particle with energy-dependent effective mass through one-dimensional potential barrier is considered. For an arbitrary potential shape we find general relations between phase, group and dwell times, and ...
A kinetic study of the thermal degradation of cetyltrimethylammonium bromide inside the mesoporous SBA-3 molecular sieve
(Elsevier Science Bv, Amsterdam, 2008)
Thermal degradation of cetyltrimethylarnmonium bromide (CTMAB) inside the mesoporous SBA-3 has been studied under non-isothermal conditions. There are two distinct although partly overlapping kinetic processes, and both ...
Digitally graded GaAs/Al0.44Ga0.56As quantum-cascade laser
(Elsevier, Amsterdam, 2003)
A method for the optimal design and realization of a GaAs/Al0.44Ga0.56As quantum-cascade laser (QCL) is presented. Firstly, an optimal, smooth active region profile is derived, using inverse spectral theory. A digitally ...
SUSY transformation of guided modes in semiconductor waveguides
(Physica Status Solidi C: Conferences, 2005)
Properly designed waveguides are of great importance for efficient operation of mid-infrared and tera-hertz quantum cascade semiconductor laser. Such waveguides comprise layers with suitably chosen doping, which determines ...
Glass formation and crystallisation behaviour of nanostructured sodium niobate by direct glass crystallisation
(Physics and Chemistry of Glasses, 2005)
The subject of this work is the study of nanostructured sodium niobate obtained by a controlled crystallisation of glass. The glass samples of the composition within the system NaNbO3-SiO2-Al2O3 were prepared by melting ...
