Recoverable platinum nanocatalysts immobilized on magnetic spherical polyelectrolyte brushes (MSPB) were synthesized and characterized by high resolution transmission electron microscope (HRTEM), thermal gravimetric analysis (TGA), X-ray diffraction (XRD), and vibrating sample magnetometer (VSM). High catalytic activi…
Iron oxide nanoparticles (IONs) were synthesized from ferrous aqueous solutions in air atmosphere by co-precipitation. The effect of [Fe+2]/[Fe+3] ratio on the properties of the nanoparticles were investigated. X-ray diffraction (XRD) patterns showed the charac- teristic peaks of iron oxide for all samples. Fourier tr…
Soft magnetic materials play an important role in broad applications, such as transformers and electrical motors. There is an interest in Soft magnetic composites (SMC) materials because of the demand for miniaturization of cores for power electronic applications, transformers, stators and rotors of electromotors. Sof…
We study bi- and polydisperse mixtures of hard sphere fluids with extreme size ratios up to 100. Simulation results are compared with previously found analytical equations of state by looking at the compressibility factor, Z, and agreement is found with much better than 1% deviation in the fluid regime. A slightly imp…
Atmospheric pressure bioplasmas are being used in a variety of bio-medical and material processing applications, surface modifications of polymers. This plasma can generate the various kinds of radicals when it contacs with the water. Especially, hydroxyl radical species have very important role in the biological and…
Recent experiments in the DIII-D tokamak have demonstrated real-time control and dissipation of post-disruption runaway electron (RE) beams. In the event that disruption avoidance, control, and mitigation schemes fail to avoid or suppress RE generation, active control of the RE beam may be an important line of defense…
A tunable shape microwave synthesis of ZnO nanospheres in a cosolvent mixture is presented. The ZnO nanospheres material is investigated as a desulfurizing sorbent in a fixed bed reactor in the temperature range 200–400 °C and compared with ZnO nanorod and platelet-like morphologies. Fresh and sulfided materials were…
We study finite quantum wires and rings in the presence of a charge-density wave gap induced by a periodic modulation of the chemical potential. We show that the Tamm-Shockley bound states emerging at the ends of the wire are stable against weak disorder and interactions, for discrete open chains and for continuum sys…
Geranyl diphosphate C-methyltransferase (GPPMT) from Streptomyces coelicolor A3(2) is the first methyltransferase discovered that modifies an acyclic isoprenoid diphosphate, geranyl diphosphate (GPP), to yield a noncanonical acyclic allylic diphosphate product, 2-methylgeranyl diphosphate, which serves as the substrat…
Biological strategies for bottom-up synthesis of inorganic crystalline and amorphous materials within topographic templates have recently become an attractive approach for fabricating complex synthetic structures. Inspired by these strategies, herein the synthesis of multi-layered, hierarchical inverse colloidal cryst…
Kinesin-1 transports various cargos along the axon by interacting with the cargos through its light chain subunit. Kinesin light chains (KLC) utilize its tetratricopeptide repeat (TPR) domain to interact with over 10 different cargos. Despite a high sequence identity between their TPR domains (87%), KLC1 and KLC2 isof…
Bulk ion toroidal rotation plays a critical role in controlling microturbulence and MHD stability as well as yielding important insight into angular momentum transport and the investigation of intrinsic rotation. So far, our understanding of bulk plasma flow in hydrogenic plasmas has been inferred from impurity ion ve…
OBJECTIVES: Surface modifications performed at the neck of dental implants, in the manner of micro-grooved surfaces, can reduce fibrous tissue encapsulation and prevent bacterial colonization, thereby improving fibrointegration and the formation of a biological seal. However, the applied procedures are technically com…
BACKGROUND: The Poisson-Boltzmann (PB) equation and its linear approximation have been widely used to describe biomolecular electrostatics. Generalized Born (GB) models offer a convenient computational approximation for the more fundamental approach based on the Poisson-Boltzmann equation, and allows estimation of pai…
The adsorption kinetics of mixtures of a biosurfactant Quillaja Bark Saponin (QBS) with a globular protein, β-lactoglobulin (β-LG) at the water/air and water/tetradecane interfaces was investigated by measuring dynamic interfacial tension with axisymmetric drop shape analysis (ADSA) and maximum bubble pressure (MBP) t…
ABSTRACT Such ternary and multinary copper chalcogenides (TMCC) as CuInSe 2 (CIS) and Cu 2 ZnSnS 4 are suitable as absorber materials for thin‐film solar cells. The valence band consists of Cu 3d and chalcogen p orbitals, and the conduction band consists of III (In) n s or IV (Sn) n s and chalcogen p orbitals. The ban…
Four cocrystals of agomelatine with urea ( 1 ), glycolic acid ( 2 ), isonicotinamide ( 3 ), and methyl4-hydroxybenzoate ( 4 ) in 1:1 stoichiometry were successfully synthesized via six kinds of synthons. The structures of 1 – 4 were determined by the single crystal X-ray diffraction, in which 1 – 3 form two-dimensiona…
By using water-soluble linear phenolic resin (PF) as C-source, a graphite-like carbonaceous surface modified TiO 2 photocatalyst (PF/TiO 2 ) was successfully synthesized through a hydrothermal process. The as-formed PF/TiO 2 exhibited significantly higher photocatalytic activity than bare TiO 2 toward the degradation…
We compare and contrast the microstructure, viscoelastic properties, and shock response of coarse-grained models of multiblock copolymer and diblock copolymers using molecular dynamics simulations. This study is motivated by the excellent dissipative and shock-mitigating properties of polyurea, speculated to arise fro…
Abstract C 3 symmetric chiral trimethylsumanene was enantioselectively synthesized through Pd-catalyzed syn-selective cyclotrimerization of an enantiomerically pure iodonorbornenone, ring-opening/closing olefin metathesis, and oxidative aromatization where the sp3 stereogenic center was transmitted to the bowl chirali…
