We report on the investigation of Co and Cu substitution effects on superconductivity and magnetism in Fe(1+y)Te(0.6)Se(0.4) single crystals. The parent Fe(1.01)Te(0.59)Se(0.41) shows a nodeless bulk superconductivity as revealed in heat capacity measurement, which is gradually suppressed by either Co or Cu doping. It…
Abstract A novel catalyst free carbon nanotube (CNT) electrode was fabricated by a Carbo Thermo Carbide Conversion (CTCC) method. The morphology and nanostructure of the CNT electrodes were characterized by transmission electron microscopy (TEM) and Raman spectroscopy. Electrochemical characterization using potassium…
Herein the synthesis of antibody-polymer conjugates, with a quite narrow dispersity based on the polymer HPMA, are reported. These conjugates are synthesized by coupling antibodies to maleimide-functionalized poly(N-(2-hydroxypropyl)-methacrylamide) (poly-HPMA) copolymers derived through reversible addition-fragmentat…
Three heat resistant cross-linked PVC foam plastics were prepared and their performances were compared with universal cross-linked PVC structural foam. The results show that these three heat resistant foams have higher glass transition temperatures (close to 100 °C) than universal structural foam (83.2 °C). Compared w…
AIMS: We tested whether phagocytic monocytes/macrophages are more susceptible than nonphagocytes to nanoparticle (NP) toxicity. MATERIALS & METHODS: We compared in vitro cell death and proinflammatory cytokine production in human monocytes, macrophages, lymphocytes and HeLa cells due to synthetic amorphous silica (SiO…
T k‐subtilisin, a subtilisin homologue (Gly70‐Gly398) from T hermococcus kodakarensis , is matured from its precursor, P ro‐ T k‐subtilisin [ T k‐subtilisin in a pro form ( G ly1‐ G ly398)], by autoprocessing and degradation of propeptide [ T k‐propeptide, a propeptide of T k‐subtilisin ( G ly1‐ L eu69)]. The scissile…
Atomistic computer simulations were performed to study the influence of radiation-induced damage on grain boundary (GB) sliding processes in bcc tungsten (W), the divertor material in the ITER tokamak and the leading candidate for the first wall material in future fusion reactors. In particular, we calculated the aver…
Zinc oxide (ZnO) thin films have attracted significant attention for application in thin film transistors (TFTs) due to their specific characteristics, such as high mobility and transparency. In this paper, the authors fabricated TFTs with ZnO thin films as channel layers deposited by plasma-assisted atomic layer depo…
This work details the characterization of anatase nanoTiO 2 particles synthesized from Malaysian mineral precursors using the XRD and EDXRF. The properties that were analyzed were its crystallite sizes, relative crystallinity, phases, and chemical composition. It was determined that the crystallite size was quite smal…
Hydrochlorothiazide (HCT) is one of the most commonly prescribed antihypertensive drugs. In an attempt to gain an insight into the physicochemical and molecular aspects controlling the complex architecture of native β-cyclodextrin (β-CD) with HCT, we performed multiple-temperature-pH isothermal titration calorimetric…
Mn(2+) doped and Ce(3+)-Mn(2+) co-doped α-Sr(2)P(2)O(7) phosphors were prepared by a traditional high-temperature solid-state reaction route. The UV-vis excitation and emission spectra for all samples were investigated. Luminescence of Mn(2+) is assigned to from two different sites, which is similar to that of Ce(3+).…
A photochromic liquid crystalline (LC) polymer {4-butoxy-2′-(4-hex-5-enyloxy)-4′-(4-hex-5-enyl-oxybenzyloxy)azobenzene, abbreviated as PLCP} was newly synthesized via the acrylic diene metathesis polymerization (H. J. Choi, et al., J. Mater. Chem., 2009, 19, 7124). Utilizing the combined techniques of differential sca…
To improve the accuracy of the static contact angle measurement in the silicone rubber aging experiments, a high accurate contact angle algorithm in combination with the circle fitting algorithm and ellipse fitting algorithm is proposed. The influence of the water drop volume and noise on the calculation accuracies of…
Classical molecular dynamics simulations were used to investigate the interaction of methyl, ethyl, and n-propyl alcohols and thiols with the hydroxylated basal surfaces of aluminum hydroxide and iron oxyhydroxide, as well as a model graphite surface. Comparisons were made to concurrently run desorption experiments in…
Two versions of a facile and efficient synthetic approach to 3,5-bis(acetaldehyde) substituted BODIPY have been developed and this compound has been used to obtain, in high yields, a variety of 3,5-divinyl BODIPY derivatives (vinylacetates, enamines, vinyl chlorides, and some multiple-functionalized products). As show…
A series of 17,17-dialkyl-3,14-diaryltetrabenzofluorenes were efficiently prepared by using Suzuki-Miyaura cross-coupling reactions of the corresponding 3,14-dibromo derivatives. Studies of the unique fluorescence properties of these compounds showed that they display intense blue to yellow fluorescence with high quan…
Bicudoa amazonica C.E. Wetzel, Lange-Bertalot & Ector gen. nov. et sp. nov. is described using light and scanning electron microscopy. It differs from ‘araphid’ genera by a unique combination of characters such as the absence of a raphe system, helictoglossae, rimoportulae, apical pore fields and linking spines, w…
Abstract The mathematical treatment of polymer modification systems, described by population balances containing convolution is discussed. The two‐dimensional case (molecular weight vs. number of branch points) was considered by utilizing approximations of distributions, expanding them in terms of Gaussian basis funct…
Electrochemically active nanostructured polypyrrole (PPy) coated with polyaniline (PANi) was deposited on an electrode followed by gluteraldehyde (GA) attachment for grafting 5′-amine modified single strand DNA (ssDNA) to form PPy–PANi–GA–ssDNA and DNA hybridization in phosphate buffered solution. Differential pulse v…
Aiming at the development of a controlled redox responsive polymeric micelle system, a series of redox-sensitive ABA triblock degradable copolymers with different amounts of disulfide bonds were synthesized. These multi-disulfide-containing amphiphilic copolymers are able to self-assemble in aqueous solution to form s…
