A charge-transfer complex between graphene oxide (GO) and pyrene dye PNPB has been synthesized by a simple ion-exchange process. Its highly specific interactions with DNA compared to other biomolecules (see scheme) allows selective and rapid detection of DNA in biological mixtures. It also exhibits broadband optical l…

The properties of BaSn 0.15 Ti 0.85 O 3 (BST) thin film with the thickness of 300 nm deposited from powder target using radio frequency (RF) magnetron sputtering technique is demonstrated. The deposition rate of BST film is estimated to be 40 nm/min, which is fast for ferroelectric materials. The dielectric constant o…
The nanoparticles having diameters of 40±20nm were synthesized by a novel technique at very low temperature of ~90C using de-ionized water as solvent. The synthesized particles were characterized by field emission scanning electron microscope (FESEM), high resolution transmission electron microscopy (HRTEM) and X-ray…
We proposed a new way to synthesize a nanocomposite consisted of cementite Fe3C nanoparticles and amorphous carbon by radio frequency plasma-enhanced chemical vapor deposition. Transmission electron microscope images show the existence of nanometric dark grains(Fe3C) embedded in a light matrix(amorphous carbon) in the…
Abstract A conical form of nano-sized quantum cluster was formed on the surface of p-type crystalline silicon [111] wafer by anode electrochemical etching in HF-based solution. The conical surface is highly effective in absorbing sunlight and transporting photoelectrons to semiconductor material. These are because eac…
A new bis-TTF donor (TTF is tetrathiafulvalene) containing a pyridine diester spacer, namely bis{2-[(6,7-tetramethylene-3-methylsulfanyltetrathiafulvalen-2-yl)sulfanyl]ethyl} pyridine-2,6-dicarboxylate-tetracyanoquinodimethane-dichloromethane (2/1/2), 2C(33)H(33)NO(4)S(12) x C(12)H(4)N(4) x 2 CH(2)Cl(2), has been synt…
Abstract A series of conjugated (poly{N‐(2‐ethylhexyl)‐3,6‐carbazole–vinylene‐alt‐[(2,5‐bisphenyl)‐1,3,4‐oxadiazole]}) and nonconjugated (poly{N‐(2‐ethylhexyl)‐3,6‐carbazole–vinylene‐alt‐[(2,5‐bisphenol)‐1,3,4‐oxadiazole]}) and poly{9,9‐dihexyl‐2,7‐fluorene–vinylene‐alt‐[(2,5‐bisphenol)‐1,3,4‐oxadiazole]}) polymers co…
Abstract A coupled‐single‐particle and Monte Carlo model was used to simulate propylene polymerization. To describe the effects of intraparticle transfer resistance on the polymerization kinetics, the polymeric multilayer model (PMLM) was applied. The reaction in each layer of the PMLM was described with the Monte Car…
Abstract Quantitative characterization of the state of dispersion and extent of exfoliation is critical in developing processing structure–property relationships in polymer–clay nanocomposites. Quantification of dispersion, exfoliation, and nanostructure in polymer–clay nanocomposites by 3D stereological parameters us…
Nanoparticles have been the subject of intensive study recently due to their interesting size- and morphology-dependent functional attributes. The assembly of nanoparticles into higher-ordered structures provides an exciting venue for the generation of novel collective properties. Herein, a versatile, fluorous tag-bas…
Three disulfoxide uranyl complexes [UO2(DBSOB)(NO3)2] n (1), [UO2(DBM)2]2(DBSOB) (2), and [UO2(PMBP)2]2(DBSOB) (3) (DBSOB = 1,4-di(butylsulfinyl)butane, HDBM = dibenzoylmethane, HPMBP = 1-phenyl-3-methyl-4-benzoyl-5-pyrazolone) were synthesized and characterized. The [UO2(NO3)2] groups are connected by bridging disulf…
The paper presents the seven contenders of nuclear reactor design fo r a desperately needed revival and also discussed how it works, advantage and disadvantages of each.
Abstract Without stabilization, polycarbonate (PC)/poly(acrylonitrile–butadiene–styrene) (ABS) blends are susceptible to a loss of mechanical properties after a few days of exposure to weathering conditions. ABS can be stabilized against terrestrial light by the use of hindered amines in combination with a UV absorber…
Abstract We demonstrate the alignment characteristics of a nematic liquid crystal on the surface of a nanoimprinted material that is a functionally graduated composite suitable for the alignment of a liquid crystal on a groove surface processed by nanoimprinting lithography. With the electro‐optic characteristics show…
This article describes the successful fabrication of europium-silicate thin film phosphor and its application to InGaN/GaN white light-emitting diodes (LEDs) in order to improve the photometric properties of the LEDs, including their correlated color temperatures (CCT) and color rendering index (CRI). The europium-sil…
Abstract Stochastic boundaries in fusion devices have been investigated in tokamaks, stellarators and reversed field pinch experiments for many years. However, since edge localized modes (ELMs) have been successfully eliminated in H‐mode plasmas at the DIII‐D tokamak [1,2] with small, edge resonant magnetic perturbati…
Abstract Electrochemical noise (EN) was used to study the pitting corrosion of J55 steel in NaCl/NaHCO 3 electrolytes. Below critical ratio for Cl − to HCO − , the corrosion rate increased with added NaCl, and conversely, decreased above that level. Also, the critical ratio was between 1 and 1.66. The PSD for potentia…
Pitch-related deposition has been a significant issue in paper mills that produce wood-containing paper grades. A component analysis showed that a mill deposit sample was a mixture of wood resin, fiber, metal cations, and other inorganics. Based on the differential scanning calorimeter (DSC) method, some critical para…
Abstract The optical, electronic, and structural properties of stoichiometric zinc sulfide clusters ((ZnS)n, n ≤ 10) have been systematically investigated using the density functional approach. The size evolution of several reactivity descriptors such as ionization potential, electron affinity, chemical hardness, and…
