Poly(ethylene 2,6-naphthalate) (PEN) was treated with ozone in the absence of radiation and the results were compared with ultraviolet (UV) photooxidation using 253·7 and 184·9 nm radiations. The surface modification of the top 2–5 nm was analyzed by X-ray photoelectron spectroscopy (XPS) for chemical changes. Higher…
Graphene oxide (GO) is effective in catalyzing a wide variety of organic reactions and a few types of polymerization reactions. No radical chain polymerizations catalyzed by GO have been reported. In this article, we probe the catalytic role and acceleration effect of GO for self-initiated radical chain polymerization…
The evolution of zinc oxide nanostructures grown on graphene by alcohol-assisted ultrasonic spray pyrolysis was investigated. The evolution of structures is strongly depended on pyrolysis parameters, i.e., precursor molarity, precursor flow rate, precursor injection/deposition time, and substrate temperature. Field-ef…
The effect of N incorporation on the structure and magnetic properties of CoPt thin films deposited on glass substrates with TiN seed layers has been investigated. During the deposition of CoPt, introducing 20% N2 into Ar atmosphere promotes the (001) texture and enhances the perpendicular coercivity of CoPt film comp…
The cation and anion recognition properties of a binuclear Eu(III) complex, [Eu2(μ2-η2-H2L)2(μ2-H2L)2(phen)2(NO3)2]⋅2CH3OH (EuL′) {H3L = 2-(3-benzoylthioureido)ethanoic acid; phen = 1,10-phenanthroline} have been thoroughly investigated in DMF solution at room temperature by luminescence method. These investigations r…
When illuminated by TM polarized waves, periodic arrays of graphene ribbons are known to exhibit plasmonic resonances due to their dual inductive–capacitive nature. It is demonstrated here that even in TE polarization, resonances can be observed in these structure. These resonances, which are of nonplasmonic origin, a…
An analytical model, in which unequal radii are replaced with an equivalent radius, is creatively proposed to predict the rolling force and roll torque in general case of snake rolling. With the model, the effects of roll radius ratio, roll speed ratio, offset distance between rolls, reduction and friction coefficient…
Quantum chemical optimization of the equilibrium structure of the trinuclear zinc complex with (E)-5-((2,6-diethylphenylimino)methyl)-2-methylquinolin-8-ol at the density functional theory level followed by Bader analysis of the electron density distribution function was performed on the basis of X-ray diffraction dat…
UNLABELLED: This study proposes liposomes as a new tool for pretargeted radioimmunotherapy (RIT) in solid tumors. Tumor pretargeting is obtained by using a bispecific monoclonal antibody [BsmAb, anti-CEA × anti-DTPA-indium complex (DTPA-In)] and pegylated radioactive liposomes containing a lipid-hapten conjugate (DSPE…
The nanoscale topography of adhesive surfaces is known to be an important factor governing cellular behavior. Previous work has shown that surface coatings composed of halloysite nanotubes enhance the adhesion, and therefore capture of, rare target cells such as circulating tumor cells. Here we demonstrate a unique fe…
The flammability behavior of wood/plastic nanocomposites made from recycled polystyrene, wood flour, and nanoclay were investigated in this study. The wood flour was mixed, using the two weight ratios of 40 wt.% and 60 wt.% with recycled polystyrene, and nanoclay was added at 0 wt.% and 5 wt.%. A coupling agent was al…
Dissolved natural organic matter (NOM) sorption at mineral surfaces can significantly affect the persistence of organic carbon in soils and sediments. Consequently, determining the mechanisms that stabilize sorbed NOM is crucial for predicting the persistence of carbon in nature. This study determined the effects of l…
When dispersed in water, nanoscale photocatalysts can aggregate into microscale secondary particles due to their high surface energy. The interaction between the incident photons and the aggregated particles is expected to be significantly changed due to their comparable length scales. Hydrodynamics of the particles a…
This work aimed at assessing the influence of different exposure systems to perform the commonly used OECD 201 freshwater algal growth inhibition test in the context of nanoparticles hazard assessment. Two distinct TiO2 nanoparticles were considered and three different exposure systems were investigated: Erlenmeyers f…
Copper(II), zinc(II), and cadmium(II) mixed-ligand complexes [M(L)(L1)], (M = Cu (I), Cd (III)), [Zn(L)(L1)(H2O)] (II) and [Cd(L)(L2)] (IV)) on the basis of N-(2-{[1-phenyl-3-methyl-5-oxo-1,5-dihydro-4H-pyrazol-4-ylidene)methyl]amino}phenyl)-4-methylbenzenesulfonamide (H2L), 2-amino-1-ethylbenzimidazole (L1), and 2-am…
Thiolated gold nanoclusters (AuNCs), sub-2 nm Au particles capped by Au(I) thiolate complexes, promise to have a myriad of applications in biomedical diagnosis and therapy as well as industrial catalysis, energy production, and monitoring of environmental pollutants. Computational simulations are a valuable tool in el…
The clean and efficient photorelease of primary and secondary alcohols is reported from the deprotection of a new photoremovable protecting group, the 9-phenyltritylone (PTO) group. Deprotection is initiated by 350 nm excitation of the PTO chromophore in the presence of triethylamine or using 447 nm light in the prese…
Gasification is a flexible technology where all types of organic waste including biomass from manure can be used as feed to the reactor. The recovery of energy from solid waste offers several benefits including substantial reduction in the total quantity of waste and reduction in environmental pollution. In the gasifi…
We report the characteristics of a right-handed helically grooved metal wire waveguide. For the helically grooved waveguide, the normal degenerate HE1 spoof surface plasmon polariton (SSPP) mode could be decomposed into two opposite circularly polarized modes, i.e., HE-1 and HE+1 SSPP modes, due to the chirality of he…
Lanthanide based luminescent materials are highly suitable as down conversion materials in combination with a UV-absorbing host material. The authors have used TiO2 as the UV-absorbing host material and investigated the energy transfer between TiO2 and 11 different lanthanide ions, Ln3+ (Ln = La, Pr, Nd, Sm, Eu, Tb, D…
