Nanostructures such as carbon nanotubes (CNTs) and semiconducting nanowires are promising candidates for developing next-generation photovoltaics. Here, we report solar cells using individual single-walled or double-walled CNTs and CdSe nanobelts arranged in simple cross-junction configurations. The CNT and CdSe nanob…
A reformate fuel cell system is one of the most promising power generation systems in the future. Thus, it is important to understand the behaviour of a fuel cell in reformate gas. In this study, the fuel cell performance in the simulated reformate gas is studied. From this study, it is concluded that the fuel cell pe…
Ag‐TiO2 nanostructured thin films with silver content of 5 vol% have been deposited on silicon, glass, and quartz substrates by RF magnetron sputtering and annealed in ambient air at 900°C for 15, 30, 60, 90, and 120 min. Their crystal structure, surface morphology, and hydrophilicity have been characterized by X‐ray…
Aqueous solutions of salts or dyes have been contained in sonochemically produced lysozyme microspheres by encapsulating an inverse emulsion in tetradecane. Release can be triggered by chemically disrupting crosslinking in the protein shell or by mechanical disruption using high intensity ultrasound.
The miscellaneously substituted silyltellanes tBu(2)PhSiTeSiMe(3) (1) and (Me(3)Si)(3)SiTeSiMe(3) were used to synthesize the cyclic tin(II) and lead(II) tellurolates [(tBu(2)PhSiTe)(4)M(2)] (M = Sn (2), Pb (3)), [tBu(2)PhSiTePbC(SiMe(3))(3)](2) (4) and the uncommon cluster compound [{(Me(3)Si)(3)SiTe}(4)Te(2)Sn(4)] (…
-crystalline chitin was added to polylactic acid (PLA), and this PLA was then heat-treated at for one minute. The crystallinity of the heat-treated PLA increased to more than 40%, and its crystallization speed also increased significantly. The temperature dependency of these materials’ relative permittivity () and rel…
The aim of this work is to assess the effect of ligand strength, symmetry, and coordination number on solid solution formation of trivalent actinides and lanthanides in carbonate and sulfate minerals. This is of particular importance in radionuclide migration where trivalent actinides such as Pu, Am, and Cm are respon…
The nanohardness H of multilayer specimens TiC/VC@Si and TiC/VC@Sapphire prepared by Pulsed-Laser-Deposition is investigated to check the existence of a superlattice effect as known from TiN/VN multilayers. In the present work the multilayer period thickness λ varies between 1.34 nm and 24.8 nm (total layer thickness…
A general approach for the modeling of fatigue induced damage in woven fabric composites and under multi-axial stress state is outlined in this paper. Guided by isotropic hardening/softening theories of plasticity and damage mechanics, a generalized bounding surface approach is presented. It is argued that the limit s…
Two new copper complexes [CuI4(L2)I5]n (1, L2 = 3,5-bis(1-ethylpyridinium-4-yl)-1,2,4-triazol-4-ide) and [CuI6(L3)3Br3]n (2, L3 = 3,5-bis(4-pyridyl)-1,2,4-triazolate) were obtained from the solvothermal reactions of different copper halides with 2,5-bis(4-pyridyl)-1,3,4-oxadiazole (L1) in the presence of aqueous ammon…
Ba 3 N 8 O 6 P 6 ,trigonal, P3 (no. 147), a =7.40227(9) , c =6.3144(1) , V =299.6 3 , Z =1, R(I) =0.008, R(P) =0.041, T =297(2) K.
In this quantum chemical investigation, NH(3) physisorption onto a model of copper sulfate impregnated silica is compared with pure silica and copper sulfate adsorbents. The physisorption process is modeled as direct binding of the NH(3) molecule to the adsorption site of the dry adsorbents and as displacement of a H(…
Cadmium sulfide (CdS) thin films of different thicknesses were deposited on corning glass by closed space sublimation (CSS) technique in a vacuum. Structural, electrical, optical, Fourier transform infrared (FTIR) with Raman spectrometric properties were investigated. X-rays diffraction used to identify the preferred…
In domestic animals, the legs function in both postural maintenance and propulsion. The crural muscles participate in actions of the tarsal and toe joints. Mammalian skeletal muscles consist of myofibers, which are histochemically classified into three myofiber types, slow-twitch/oxidative (SO) or type I, fast-twitch/…
This paper deals with the diffraction of a transverse magnetic (TM) plane wave by a perfectly conductive periodic surface by an integral method. However, it is known that a conventional integral method does not work for a critical angle of incidence, because of divergence of a periodic Green's function (integral kerne…
Here, we report the one-step synthesis of N-acetylglucosamine-functionalized gold nanoparticle (NAG–AuNP), which then served as a facile, economic, highly sensitive and selective sensor for the detection of lectin from wheat germ, based on colorimetric and resonance light scattering signals.
TiO2porous electrodes have been fabricated for photoelectrodes in dye-sensitized solar cells (DSCs) using TiO2screen-printing paste from nanocrystalline TiO2powder dried from the synthesized sol. We prepared the TiO2screen-printing paste by two different methods to disperse the nanocrystalline TiO2powder: a “ball-mill…
A novel noncollagenous acidic protein was identified from the scales of goldfish (Carassius auratus), a freshwater teleost. Using an in vitro calcium phosphate crystallization assay, the EDTA-soluble fraction from these scales was screened for crystallization inhibitory activity, and a highly phosphorylated glycoprote…
Nanometric particles of germanium‐doped TiO 2 were prepared by homogeneous hydrolysis of TiOSO 4 and GeCl 4 in an aqueous solution using urea as the precipitation agent. Structural evolution during heating of these starting Ge‐Ti oxide powders was studied by X‐ray diffraction (XRD) and high‐temperature X‐ray powder di…
Colloidal synthesis of metal chalcogenides has been developed to be used as nanocrystal inks to produce high efficiency solar cells with the lower fabrication costs. Recent research on these materials has focused on the use of abundant and low toxicity elements such copper, iron, tin, lead and sulphur. Several methods…
