In recent years nano‐sized particles have been focused on bacteriostasis. We investigated antimicrobial activities by applying two types of silver nanoparticles on cotton fabric. These are MesoSilver particles and silver chloride compounds (Silpure). Silver chloride, used in aqueous dispersion, is mixed with a monomer…
BACKGROUND: Methylotrophic (methanol-utilizing) bacteria offer great potential as cell factories in the production of numerous products from biomass-derived methanol. Bio-methanol is essentially a non-food substrate, an advantage over sugar-utilizing cell factories. Low-value products as well as fine chemicals and adv…
The title problem is solved for an internally pressurised hole within the framework of plane-stress finite-strain plasticity. Material behaviour is modelled by the Tresca-associated flow theory with arbitrary hardening (softening), accounting for thickness changes and elastic compressibility. Three distinct plastic zo…
Electrical and gas sensing properties polyaniline-chloroaluminium phthalocyanine (PAni-ClAlPc) composite thin films were investigated to study the gas sensing behavior of composites. Devices (chemiresistor gas sensors) were prepared by spin coating method from PAni as the base of composites and ClAlPc (with different…
A modified procedure for electrocrystallization of organic conductors with paramagnetic anions has been proposed and a number of known and new BEDT-TTF salts with tris(oxalato)ferrate anion have been synthesized.
Iron (III) chloride tetraphenylporphyrin (FeTPPCl) thin films are prepared on quartz and glass substrates at room temperature by thermal evaporation technique. The X-ray diffraction showed the amorphous nature for both the as-deposited and the annealed films at 423 K in air for 2 h, whereas the powder has the tetragon…
Advances in basic knowledge relevant to the pseudocapacitive and electrocatalytic properties of RuO(2) materials require a detailed understanding of the redox chemistry that occurs at the electrode interface. Although several redox processes have been identified via dc cyclic voltammograms derived from surface-confine…
We theoretically consider the commensurability problem of AB diblock lamellar phase confined between parallel plates, in cylinder, and in sphere calculating the free energy of confined lamellar phase which is generalized in terms of dimensionality of confinement (d) and conformational asymmetry (ɛ). We find that the f…
In this paper we have reported synthesis and characterization of Dy3+ and Eu3+ activated Na2Mg(PO4)F, Na2Ca(PO4)F and Na2Sr(PO4)F phosphors. These phosphors were prepared by combustion synthesis and characterized by XRD and photoluminescence techniques. Dy3+ ion gives PL emission in blue and yellow region of the visib…
The electrochemical synthesis of a new dithienylcyclopentadienone-derivative/3-methylthiopene copolymer was performed by cyclic voltammetry. The obtained material shows redox processes very close to those from the pristine DTCPD. A new redox process at -1.24 V, with a large anodic shift (0.51 V) related to the poly(3-…
Pure and Mn doped Ba 0.6 Sr 0.4 TiO 3 (0.5%, 2%) (BST) thin films were epitaxially grown on the (001) LaAlO 3 using pulsed laser deposition. Microstructural characterizations indicate that the as-grown thin films have excellent single crystalline quality and epitaxial nature with an atomically sharp interface and an i…
An optical black hole is studied using a parallel radially dependent finite-difference time-domain (FDTD) simulation technique. The device requires non-dispersive metamaterial structures and is capable of broadband operation, based on transformation optics. Excellent absorption is demonstrated for different angles of…
Abstract Electrochemical capacitive behaviour of the electropolymeric nickel tetra‐aminophthalocyanine (poly‐NiTAPc) supported on multiwalled carbon nanotube (MWCNT) platform is described. From the data in 1 M H 2 SO 4 , the MWCNT‐poly‐NiTAPc exhibited superior capacitance (112 mF cm −2 or 777 F g −1 ). The supercapac…
4-Hydroxy-4-methyl-2-oxoglutarate/4-carboxy-4-hydroxy-2-oxoadipate (HMG/CHA) aldolase from Pseudomonas putida F1 catalyzes the last step of the bacterial protocatechuate 4,5-cleavage pathway. The preferred substrates of the enzyme are 2-keto-4-hydroxy acids with a 4-carboxylate substitution. The enzyme also exhibits o…
A ‘bottom-up’ approach is utilized for assembling magnetic nanoparticles in a mesoporous silica solid for the generation of a magnetic nanocomposite. Grafting of a palladium complex of the type (L)2PdCl2 (L=Si(OMe)3 functionalized PPh3) results in an active, recyclable catalyst for CC coupling reactions.
The kinetics for NO reduction over supported platinum under lean condition were investigated by first-principles-based kinetic Monte Carlo simulation over three-dimensional Pt nanoparticles. Model platinum nanoparticles with diameters ranging from 2.3 to 4.6 nm were constructed using a truncated octahedral cluster con…
Abstract In recent years, the interest for using biogas derived from biomass as fuel in solid oxide fuel cells (SOFCs) has increased. To maximise the biogas to electrical energy output, it is important to study the effects of the main biogas components (CH 4 and CO 2 ), minor ones and traces (e.g. H 2 S) on performanc…
Abstract The dielectric properties of polyurethane (PUR) latex–boehmite alumina nanocomposites were investigated by means of broadband dielectric spectroscopy in the temperature range −100 °C to 70 °C. The concentration of the filler (alumina) was kept constant at 10 phr for all specimens, whereas the mean particle di…
To evaluate the feasibility of a strategy to partially replace polyamide-6 (PA6) with poly(lactic acid) (PLA), the morphology, mechanical, and thermal properties of PA6/PLA blending systems were investigated. Polyethylene-octene elastomer (POE) and POE grafted with maleic anhydride (POE-g-MAH) are added to improve the…
We developed a novel one-pot polyol approach for the synthesis of biocompatible CdSe quantum dots (QDs) using poly(acrylic acid) (PAA) as a capping ligand at 240°C. The morphological and structural characterization confirmed the formation of biocompatible and monodisperse CdSe QDs with several nanometers in size. The…
