First principles-based kinetic Monte Carlo (kMC) simulations are performed for the CO oxidation on RuO(2) (110) under steady-state reaction conditions. The simulations include a set of elementary reaction steps with activation energies taken from three different ab initio density functional theory studies. Critical co…
We implemented a nanoelectronic interface between graphene field effect transistors (FETs) and soluble proteins. This enables production of bioelectronic devices that combine functionalities of the biomolecular and inorganic components. The method serves to link polyhistidine-tagged proteins to graphene FETs using the…
Cation-exchange reactions have greatly expanded the types of nanoparticle compositions and structures that can be prepared. For instance, cation-exchange reactions can be utilized for preparation of core/shell quantum dots with improved (photo)stability and photoluminescence quantum yield. Understanding the structure…
The preparation, characterization, and photochromic properties of a mononuclear gold(I) complex (1oo) with two identical DTE-acetylides and a dinuclear gold(I) complex (2ooo) with both DTE-acetylide and DTE-diphosphine are described. Both gold(I) complexes exhibit multistep and multiple photocyclization/cycloreversion…
Two three-dimensional (3D) Fe(II) porous metal–organic frameworks (MOFs) [Fe 2 (H 0.67 bdt) 3 ]·13H 2 O ( 1 ·13H 2 O) and [Fe 3 (ox)(H 0.67 bdt) 3 (H 2 O) 2 ]·solvent ( 2 ·solvent) (H 2 bdt = 5,5′-(1,4-phenylene)bis(1H-tetrazole); H 2 ox = oxalic acid; solvent = 10H 2 O and 9CH 3 OH for 2 ·9MeOH and 6H 2 O and 5C 4 H…
Cancer is one of the leading causes of death in most parts of the world and is a very serious cause of concern particularly in developing countries. In this work, we prepared and evaluated the aptamer-labeled paclitaxel-loaded poly(lactic- co -glycolic acid) (PLGA) nanoparticles (Apt-PTX-PLGA NPs) which can ameliorate…
Bandpass filters are reported based on double-stacked metamaterial layers separated by an air gap for operation at terahertz frequencies. Several stacking configurations were investigated designed for a ~0.5 THz center frequency. The filters exhibited improved spectral transmission properties when compared with conven…
The specific properties of nanoscale particles, large surface-to-mass ratios and highly reactive surfaces, have increased their commercial application in many fields. However, the same properties are also important for the interaction and bioaccumulation of the nonbiodegradable nanoscale particles in a biological syst…
Abstract Hybrid composites based on isophthalate polyester and vinyl ester resin were fabricated with glass and bamboo fibers. 25, 50, and 75 wt % of glass fibers were replaced by bamboo fibers of the optimized glass fiber reinforced composites and were subjected to dynamical mechanical analysis to determine the dynam…
We calculate the electronic local density of states (LDOS) of DNA nucleotide bases (A,C,G,T), deposited on graphene. We observe significant base-dependent features in the LDOS in an energy range within a few electronvolts of the Fermi level. These features can serve as electronic fingerprints for the identification of…
A series of organic–inorganic hybrid lacunary Keggin silicotungstate 3d-4f heterometallic derivatives, {[Cu (en) 2 ] 1.5 Ln[(α-SiW 11 O 39 ) 2 ]} 2 20– [Ln = Gd III for 1, Tb III for 2, Dy III for 3, Er III for 4, Lu III for 5 ], {[Cu(en) 2 ] 1.5 Ln[(α-SiW 11 O 39 )]} 2– [Ln = La III for 6, Ce III, for 7 ] and {[Cu(en…
A large scale homogenous invisibility cloak functioning at terahertz frequencies is reported. The terahertz invisibility device features a large concealed volume, low loss, and broad bandwidth. In particular, it is capable of hiding objects with a dimension nearly an order of magnitude larger than that of its lithogra…
Far red emitting persistent luminescence nanoparticles (PLNP) were synthesized and functionalized with biotin to study their targeting ability toward biotin-binding proteins. First, the interaction of biotin-decorated PLNP with streptavidin, immobilized on a plate, was shown to be highly dependent on the presence of a…
This work addresses the synthesis of carbon nanomaterials (CNMs) by up-cycling common solid wastes. These feedstocks could supersede the use of costly and often toxic or highly flammable chemicals, such as hydrocarbon gases, carbon monoxide, and hydrogen, which are commonly used as feedstocks in current nanomanufactur…
A combined adsorption-discharge plasma catalytic process was used for the removal of NO(x) using zeolites as catalysts without external heating. It was found that the types of plasma carrier gases exert great effect on the conversion of adsorbed NO(x). The conversion of adsorbed NO(x) is much lower in N(2) plasma than…
We show how the ground state of phosphorus, black phosphorus, and the $\ensuremath{\alpha}$-As type modification, next-lying on increasing pressure, are tightly connected over a Peierls intermediate. We unravel an intrinsic reactivity given by lone pairs, which are conserved during phase transition and are not suppres…
We report a strategy that combines supramolecular assembly and solvent annealing to manipulate the microdomain orientation in block copolymer thin films. In supramolecular thin films formed by polystyrene- b -poly(4-vinylpyridine) (PS- b -P4VP) with 3-pentadecylphenol (PDP) hydrogen-bonded onto P4VP blocks, where PS b…
An environmentally benign surface modification process for plastic films was demonstrated by fabricating composite coatings through layer-by-layer assembly with green solid materials: aqueous dispersions of two kinds of crystalline polysaccharide nanofibrils. Anionic cellulose nanofibrils were obtained by the TEMPO (2…
BACKGROUND: Inactive protein inclusion bodies occur commonly in Escherichia coli (E. coli) cells expressing heterologous proteins. Previously several independent groups have found that active protein aggregates or pseudo inclusion bodies can be induced by a fusion partner such as a cellulose binding domain from Clostr…
Electrodeposition of high-surface-area nanoporous Au-Cu foams under conditions of hydrogen codeposition is studied. The honeycomb-like Au(x)Cu(100-x) foams with 0 ≤ x ≤ 100 are electrodeposited by controlling the amount of corresponding ions in the solution. The amount of metal ions in deposited films follows that in…
