Electron transport properties at n-type LaAlO3/SrTiO3 interfaces have been investigated numerically. Carrier distributions, band structures, and sheet density have been calculated by solving Schrödinger equations with Poisson equation in a self-consistent manner for various LaAlO3/SrTiO3 interfaces with and without at…
Isocitrate deyhdrogenase (IDH) is a reversible enzyme in the tricarboxylic acid cycle that catalyzes the NAD(P)(+)-dependent oxidative decarboxylation of isocitrate to α-ketoglutarate (αKG) and the NAD(P)H/CO2-dependent reductive carboxylation of αKG to isocitrate. The IDH gene from Streptococcus mutans was fused with…
Synthetic vessel grafts have been used as vascular substitutes for cardiovascular bypass procedures. In this study, we developed a novel tubular double-layered poly(l-lactide-co-ϵ-caprolactone) scaffold that did not require pretreatment with cell seeding by promoting autologous tissue regeneration by inducing the prol…
Widely applied techniques for the fault location based on AE method are: (i) measurement of the time difference of arrival (TDOA) of the acoustic signals, (ii) measurement of the acoustic signal amplitude in different areas of a transformer tank (standard auscultatory technique, SAT), (iii) advanced auscultatory techn…
Abstract This paper reviews our efforts to simulate methanol synthesis from CO and H 2 on defective ZnO surfaces using advanced molecular dynamics techniques. This apparently simple chemical reaction occurring on a seemingly well‐defined surface appears to be astonishingly complex. First of all, the preferred oxidatio…
Formation of intrinsic acceptor defects in ZnO is rare due to the low formation energy of donors. Understanding this phenomenon is of interest for the fabrication of high quality light emitting diodes. Herein, we examine the temperature dependent formation of defects in nanocrystalline ZnO through a combination of X-r…
We compute the absorption efficiency ( Q abs ) of forsterite using the discrete dipole approximation in order to identify and describe what characteristics of crystal grain shape and size are important to the shape, peak location, and relative strength of spectral features in the 8–40 μm wavelength range. Using the DD…
The increasing concern on energy and the global warming due to the depletion of fossil fuel demands to search the alternative renewable energy resources for covering the energy crisis in the coming decade. A very popular renewable source called photovoltaic device is antici‐ pated to solve energy problem, which conver…
Abstract The interaction and reaction of MeOH with Cu is of foremost importance in a range of heterogeneously catalyzed processes. A critical intermediate in the molecular transformation of MeOH on Cu‐based catalysts is the methoxy species, the formation of which comprises the first elementary step in the MeOH steam r…
Abstract The properties of manganite/ruthenate superlattices are reviewed with a specific focus on the manganite/ruthenate interface. La 0.7 Sr 0.3 MnO 3 /SrRuO 3 and Pr 0.7 Ca 0.3 MnO 3 /SrRuO 3 superlattices grow with a high crystalline perfection as illustrated in the figure to the right: at the interface the indiv…
Prior to the development of commercial applications of magnetic refrigerator technology, a large magnetocaloric effect (MCE) in polycrystalline materials must be realized for relatively low magnetic field changes. To increase the MCE, a crystallographic alignment technique, consisting of thermal cycling about the mart…
Hoodia gordonii (family: Apocynaceae) is used traditionally by the Khoi-San tribes to control hunger. It has become extremely popular and has triggered commercial interest due to its appetite suppressant property. The present study was undertaken to investigate the appetite regulatory mechanism and associated metaboli…
The adsorption of 4‐nitroanisole on silver colloidal nanoparticles was investigated by surface‐enhanced Raman spectroscopy (SERS). Actually, the chemical binding with a metal substrate may play a role in changing the electronic structure of this molecule, which can be considered a push–pull chromophore, because an int…
Abstract The strong influence of the support properties on the activity of gold catalysts has been observed in many publications. The most studied reaction in this respect seems to be CO‐oxidation, for which gold catalysts have outstanding activity. However, since in most studies the support properties are also import…
Abstract The formation of related polymer/TiO 2 nanocomposites is studied using two alternative synthetic procedures. The triflic acid anhydride‐catalyzed twin‐polymerization (TP) of (μ 4 ‐oxido)‐hexakis(μ‐furan‐2‐methoxo)‐octakis(furan‐2‐methoxo)‐tetratitanium ( 1) and (μ 4 ‐oxido)‐hexakis(μ‐thiophene‐2‐methoxo)‐octa…
Despite the relatively low mechanical properties respect to the aluminium alloys but due to high thermal exchange capacity, pure aluminium (AA1XXX series) is widespread for industrial applications for heat exchanger components or cooling systems (like refrigerator systems). The corrosion protection properties of alumi…
Two oligomeric families of materials containing thiophene-carbonyl and thiophene-dicarbonyl units have been synthesized and characterized with emphasis on structural, electrochemical, and electronic properties. Three thiophene-carbonyl derivatives containing 1, 2, and 3 carbonyl groups exhibited one, two, and three on…
The low-field phase of the organic superconductor (TMTSF)(2)ClO(4) is studied by muon-spin rotation. The zero temperature limit of the magnetic penetration depth within the TMTSF layers is obtained to be λ(ab)(0) = 0.86(2) μm. Temperature dependence of the muon-spin relaxation shows no indication of gap nodes on the F…
Lyophilic but not sticky! A lyophilic yet nonwettable surface seems self-contradictory, however, a nanostructured super-lyorepellent surface is used to reveal that a lyophilic nonwettable state is theoretically feasible in an oil/water/air/solid four-phase system. This finding may throw light on multiphase interface b…
A highly selective method is described for controlling the degradation of polyhydroxyalkanoates, PHA, via a reduction reaction that uses lithium borohydride. Using this method, oligo(hydroxyalkanoate)diols derived from a poly(3-hydroxybutyrate-co-4-hydroxybutyrate) biopolyester [poly(3HB-co-4HB)] and from synthetic at…
