A simple size-controlled synthesis of cadmium sulfide (CdS) nanoparticle (NP) cores in the cavity of apoferritin from horse spleen (HsAFr) was performed by a slow chemical reaction synthesis and a two-step synthesis protocol. We found that the CdS NP core synthesis was slow and that premature CdS NP cores were formed…
Reaction of 2,4,6-trichloro-1,3,5-triazine with lithiated tetrathiafulvalene (TTF) in stoichiometric conditions, followed by treatment with sodium methanolate, provides mono- and bis(TTF)-triazines as new covalently linked (multi)donor-acceptor systems. Single-crystal X-ray analyses reveal planar structures for both c…
This study determined the impact of pasteurization, high-pressure processing (HPP), and retorting on the barrier properties of nylon 6 (N6), nylon 6/ethylene vinyl alcohol (N6/EVOH), and nylon 6/nanocomposite (N6/nano) materials. The pasteurized and high-pressure treated films were coextruded with low-density polyethy…
Mn-doped TiO(2) nanocrystals encapsulated in a carbon layer (Ti(1-x)Mn(x)O(2)@C) were synthesized by the one-pot RAPET (reaction under autogenic pressure at elevated temperature) technique. Manganese was doped into the body-centered tetragonal TiO(2) anatase phase to give a Mn:Ti atomic ratio of 1%, 5% and 10%. The su…
High-quality ZnO epitaxial films have been grown by pulsed-laser deposition on Si (111) substrates using a nanothick high- k oxide Y 2 O 3 buffer layer. Determined by X-ray diffraction and transmission electron microscopy, the epitaxial relationship between ZnO and Y 2 O 3 follows (0001)⟨21̅1̅0⟩ ZnO ||(111)⟨101̅⟩ Y 2…
One-dimensional In 2 O 3 (ZnO) m superlattice wires were first synthesized on silicon substrates by evaporating a mixture of In and ZnO powders. The high-resolution transmission electron microscopy image indicates that the wires have a superlattice structure along their length, which consists of alternating stacks of…
Abstract In this paper, we focus on current–voltage ( I–V ) characteristics in several kinds of quasi-one-dimensional (quasi-1D) nanofibers to investigate their electronic transport properties covering a wide temperature range from 300 down to 2 K. Since the complex structures composed of ordered conductive regions in…
Aged thermoplastic starch (TPS), plasticized with hydrophilic plasticizers such as glycerol, shows brittle property. It is critical to develop tough TPS without using hydrophilic plasticizers. In this work, polyurethane prepolymer (PUP) was synthesized and mixed reactively with TPS in an intensive mixer to prepare mod…
Magnesium ions are widely found in calcium-based biominerals as an accessory component. In this report, the influence of magnesium ions on the crystal growth of CaCO 3 was investigated on the basis of the nanostructure. The morphology of calcite grown in a supersaturated solution was drastically changed from a regular…
Carbon nanotubes (CNTs) have advantages as conductive fillers due to their large aspect ratio and excellent conductivity. In this study, a novel silver/conducting polymer composite was developed by the incorporation of silver-plated CNTs. It is important to achieve a homogeneous dispersion of nanotubes and to improve…
Abstract The present article reports the preparation and characterization of fluoroelastomer/multi‐walled nanotube hybrid nanocomposites prepared by conventional rubber mixing using a two‐roll mill. The morphology of the resulting hybrid nanocomposites were characterized by X‐ray diffraction (XRD), scanning (SEM) and…
Using the five-site transferable intermolecular potential (TIP5P) we perform molecular dynamics simulations to investigate the relationship between the excess entropy and anomalies of water. We find that the two-body excess entropy is an ideal quantity to predict the regions of structural, dynamic, and thermodynamic a…
Silver metal nanoparticles (Nps) are extensively used in different areas of research and technology due to their interesting optical, thermal and electric properties, especially for bare core and core-shell nanostructures with sizes smaller than 10 nm. Since these properties are core-shell size-dependent, size measure…
Eleven potential polyhydroxybutyrates (PHB) producers were successfully screened from treated palm oil waste water using acetate as sole carbon and energy sources and on nitrogen limiting media with Nile Blue A dye to screen for PHB accumulation. Orange fluorescence color, produced upon binding of the dye to polymer g…
The production of AlN by thermal reduction of Al 2 O 3 in a N 2 flow, with C/CH 4 as reducing agents, is investigated using concentrated thermal radiation as the energy source of high-temperature process heat. Samples were directly exposed to radiative fluxes equivalent to peak solar concentration ratios exceeding 450…
Abstract This article reports the synthesis and characterization of copolymers based on aniline and substituted anilines by using dodecylbenzene sulfonic acid as a dopant. The copolymers were soluble in organic solvents, such as methanol, ethanol, isopropanol, N ‐methylpyrrolidinone, dimethylsulphoxide, and have condu…
Abstract Natural fiber polyethylene composites containing kenaf fibers, wood flour, newsprint, and rice hulls at 25 and 50% (by weight) fiber content were sampled and studied using thermogravimetric analysis (TGA). The effects of fiber type and content, compatibilizer and heating rate on the thermal stability and degr…
Highly facile and efficient synthesis of a variety of meso-functionalized porphyrins was accomplished by PhI(OAc)(2)-NaAuCl(4) mediated direct nucleophilic substitution reactions of [5,10,15-triphenylporphyrinato]zinc(II) (Zn1) with different amines and thiophenols. When [5,15-dibromo-10,20-diphenylporphyrinato]zinc(I…
Radial elastic corrugation of multiwalled carbon nanotubes under hydrostatic pressure is demonstrated by using the continuum elastic theory. Various corrugation patterns are observed under a pressure of several GPa, wherein the stable cross-sectional shape depends on the innermost tube diameter D and the total number…
Moisture transmission properties are most important for fabric comfort. We have studied the moisture transmission properties of the plain-woven fabric produced with polyester–viscose-(PV) blended yarns. PV-blended yarns of varying blend proportion, yarn count and twist levels have been used for fabric manufacture. A t…
