The time-stepping finite-element method (FEM) has become a powerful tool in solving transient electromagnetic fields. The formulation can include complex issues such as time harmonics and space harmonics, nonlinear magnetic property of iron materials, external circuit, and mechanical motion in the system equations. Ho…
As essential enzymes in the body, monoamine oxidases (MAOs), including MAO-B, help maintain the proper balance of neurotransmitters and other dietary and biogenic amines. Thus, development of convenient and continuous assays for MAO-B and its inhibitor-screening is highly desirable since the inhibitors have implicatio…
For a mixed oxide-ion and electron conducting oxide, with oxygen vacancies (V(O)) and electrons (e') or holes (h ) as charge carriers, a flux of (V(O)) (J(i)) can in principle be driven, not only directly by its own electrochemical potential gradient (inverted Delta eta(i)), but also indirectly by that of electrons (i…
A new diphosphonate-functionalized polyoxomolybdate L,D-(NH4)6{MoV2O4[(MoVI2O6)NH3CH2CH2CH2C(O)(PO3)2]2}·10H2O (1) has been synthesized by the reaction of alendronic acid with {Mo2O4(H2O)6}2+ fragments. In the structure, a restriction of “folding” alkyl induced chiral polyoxometalate has been observed.
Charge-transfer processes in single QDs with p-type NiO nanoparticles result in fluorescence intensity and lifetime quenching, suppression of blinking behavior and enhancement of the dot's survival time.
2,1,3-Benzothiadiazole (BTD)-containing red emitter was chemically conjugated onto amphiphilic poly(ethylene glycol)-block-poly(epsilon-caprolactone) (PEG-b-PCL) copolymers to form two new fluorophore-conjugated block copolymers (P5 and P7). P5 is a cationic amino group-containing polymer, whereas, P7 is a neutral pol…
A new octanuclear manganese cluster [Mn(8)(Hpmide)(4)O(4)(EtCOO)(6)](ClO(4))(2) (1) is achieved by employing Hpmide as the ligand, and this paper examines the synthesis, X-ray structure, high-field electron paramagnetic resonance (HFEPR), magnetization hysteresis loops and magnetic susceptibilities. Complex 1 was prep…
As a first step towards mechanistic studies of fuel cell electrodes with both well-defined and functionally representative structural features, two-dimensional anti-dot metal films with tunable features are prepared. The fabrication employs a facile, sacrificial templating method, known as polymer sphere lithography,…
IR-transparent chalcogenide glass-ceramics were fabricated through a careful ceramization process of the as-prepared 65 GeS(2) x 25 Ga(2)S(3) x 10 LiI glasses at a temperature of 403 degrees C for various durations. Owing to the precipitation of Li(x)Ga(y)S(z) crystals with a Ga(2)S(3)-like structure, clear second-har…
The Sb doped tin dioxide electrode (Sb-doped SnO 2 ) inter-layer was prepared using electroposition layer-by-layer onto a titanium plate, and the Sb-doped SnO 2 surface catalytic layer (Ti/SnO 2 -Sb) was prepared using thermo-decomposition method. Accelerated service life tests were carried out in 0.5 M H 2 SO 4 solut…
Tunable emission of binary organic nanobelts was realized via the fluorescence resonance energy transfer (FRET) process, which can be exploited for the detection of acid and basic chemical vapors.
The electrical conductivity of carbon nanotubes varies, depending on the temperature and the radius and pitch of the sample. In majority cases, the resistance decreases with increasing temperature, suggesting a thermally activated process. The standard band theory based on the Wigner–Seitz cell model predicts a gaples…
The cross-linked supramolecular structure of prepared polyester based nanoparticles enable increased and efficient small molecule drug loading after nanoparticle formation and post-modification with targeting peptides via thiol-ene 'click' chemistry. It could be demonstrated that the drug loading does not influence th…
Thiol-ene reaction with thiol-containing polysilsesquioxanes and multifunctional allyl compounds produced new type of organic-inorganic hybrid materials. Thiol-containing polysilsesquioxanes were prepared from the hydrolysis and condensation of mercaptopropyltrimethoxysilane. When triallylisocianate (TAIC) as multifun…
Data mining, involving cross examination of cluster structure pools collected for ZnO, GaN, LiF and AgI, has been applied to predict plausible cluster structures of related binary materials. We consider the energy landscapes of (MX)(12) clusters for materials that possess tetrahedral bulk phases, wurtzite or sphalerit…
By applying pulsed electrodeposition instead of continuous electrodeposition for the consecutive preparation of each layer, a favorable modification is targeted of photoelectrocatalytic activity of the couple. The morphology, structure, and related composition distribution of the films onto stainless steel substrates…
Segmented poly(urethane urea)s (SPUUs) based on aliphatic diisocyanato (2,6-diisocyanato methyl caproate (lysine-based diisocyanate, LDI)), poly(epsilon-caprolactone diol)s (PCLs) with molecular weights 530, 1250 and 2000, and 1,4-butanediamine were synthesized in absence of catalyst. The resulting SPUUs, with differe…
The effect of simple shear deformation by equal-channel angular pressing (ECAP) for one pass on the texture and ridging of ferritic stainless steel sheets with 16 mass% chromium has been investigated. Hot rolled and annealed sheets of 4 mm thickness were ECA-pressed for one pass, prior to cold rolling and final anneal…
Luminescent benzocarbazole anions (BCZC) intercalated into the interlayer region of Mg-Al-layered double hydroxides (BCZC/LDH) with different layered charge densities (LCD) were prepared. The structure and chemical composition of the composites were characterized by X-ray diffraction, elemental analysis, thermogravime…
A novel approach to identify structures and quantify the absolute amounts of individual ligands on multi-functionalized gold nanoparticles by an FTIR and HPLC/MS/UV/CLND method has been developed.
