We report a new fabrication approach to highly sensitive optical sensors by combining the techniques of electrospinning and electrostatic layer-by-layer adsorption. A fluorescent probe, hydrolyzed poly[2-(3-thienyl) ethanol butoxy carbonyl-methyl urethane] (H-PURET), was electrostatically assembled onto the surface of…
Abstract Semi‐interpenetrating polymer networks (IPNs) have been prepared from polyurethane anionomers and poly(vinyl chloride) using sequential polymerization technique. These IPNs were compression molded and obtained as tough films. The hydrogen bonding interaction, glass transition temperature, and thermal stabilit…
Abstract Anionic polymerization of lauryl methacrylate (LMA) with 1,1‐diphenylhexyl lithium in tetrahydrofuran (THF) at −40 °C resulted in a multimodal and broad molecular weight distribution (MWD) with poor initiator efficiency. In the presence of additives such as dilithium salt of triethylene glycol (G 3 Li 2 ), Li…
The methods of hydrochloric acid extraction, liquid–solid adsorption, and complexation were used to remove basic nitrogen compounds from gasoline, and the efficiencies of three removal methods were studied. The experimental results show that the optimum range of the concentration of hydrochloric acid is 0.05 ∼ 1.0 mol…
Phase transition temperature and associated energies in hard high melting microcrystalline waxes and its various blend with paraffin wax (melting range from 60 to 97°C) have been determined by DSC in both heating and cooling mode. The dependence of these on the composition and properties of waxes have been analyzed. T…
Abstract In the present work the natural and maleic anhydride esterified fibers of banana, hemp, and sisal are used as reinforcers in novolac resin in the ratio of 40:60 (wt/wt) respectively. Absorption of water and steam in these wood/polymer composites is studied. The absorption of water increases with increase in t…
Abstract A series of novel, soluble polyazomethines bearing fluorene and carbazole moieties in the main chain and solubility‐improving moieties in the side group (dibutyl, ethylhexyl, thienylethyloxy, furyl, and fluorenyl) were synthesized. Good‐quality films of these polymers were prepared through the conventional so…
Abstract Fully crosslinked, stable poly(styrene‐ co ‐divinylbenzene) microspheres, which are composed of various concentrations of divilylbenzene from 5 to 75 mol % based on styrene monomer, were prepared without a significant particle coagulation by the precipitation polymerization. The number‐average particle diamet…
Abstract A series of low density polyethylene (LDPE)/starch blend films with starch content ranging from 2.5 to 50% were prepared by two methods, namely, solution blending followed by thermopress and extrusion methods. The LDPE/starch films prepared by both the methods were studied for physicomechanical properties suc…
We report a first-principle study of the electronic and conduction properties of a quadruple-helix guanine wire (G4-wire), a DNA-derivative, with inner potassium ions. The analysis of the electronic structure highlights the presence of energy manifolds that are equivalent to the bands of (semi)conducting materials, an…
Abstract The first successful example of a polymer‐clay hybrid was nylon‐clay hybrid (NCH), which is a nano‐meter‐sized composite of nylon‐6 and 1‐nm‐thick exfoliated aluminosilicate layers of the clay mineral. NCH was found and developed at Toyota Central Research and Development Laboratories over 17 years ago. The N…
The macroscopic molecular self-assembly of an amphiphilic hyperbranched copolymer in acetone generated multiwalled tubes millimeters in diameter and centimeters in length. The thickness of the tube walls approaches 400 nanometers, and the walls have an inhomogeneous lamella structure that alternates between ordered hy…
Three kimberlite pipes are reported from Siddanpalli village in Gadwal area, Mahbubnagar district, Andhra Pradesh, bringing to light a new kimberlite cluster. Significance of the find lies in the fact that these kimberlite pipes are located in the Krishna river basin well known for its alluvial diamond mining activity…
Wheelabrator Technologies is owner and operator of the 2250 ton per day North Broward County, Florida, facility. The plant consists of three lines rated at 750 tons/day. Each line is equipped with a spray dryer absorber/fabric filter. The original fabric filter design was a shake-deflate baghouse with ten compartments…
The development of new high-performance refrigerants has been highly desired from the viewpoints of energy efficiency and environmental safety. Recently, we developed promising magnetic refrigerant compounds La(Fe1-xSix)13 (0.86≤x≤0.90), that show the first-order of itinerant-electron metamagnetic transition from the…
According to increase in a waste scrap, a process is noticed in which a waste scraps is consumed for sheet steel production within severe restriction of impurities concentration. In this study, evaluation of the effect on environmental load decline by LCA is applied to this new recycling technology.Target of this stud…
A higher-order shear-deformable beam model with gradient-dependent plasticity regularisation is presented in this work. The model takes into account a realistic non-linear variation of stresses and strains through the beam thickness. This enables mixed mode fracture analysis. Numerical results are presented for a mult…
The effects of alloy composition and heat treatment on the damping capacity and strength of MnCuNiFe damping alloys were investigated in this study. It is observed that: When Mn composition is varied from 70.5 to 75.9 mass%, the fcc-fct phase transformation temperature increases with the increase of Mn composition at…
Present results on intermediate temperature-operating solid oxide fuel cells (IT-SOFC) are mainly focused to obtain higher performance of single cell at lower operating temperature, especially with planar type. In order to develop a 1 kW-class SOFC system for Residential Power Generation (RPG) application that can be…
Recently, we reported about successful synthesis of crystalline carbyne from graphite by step‐like shock‐wave compression. Thin graphite foil was placed into the recovery assembly between two thick PTFE dicks. Shock pressure was 36 GPa, shock temperature was estimated as 730 K. In the recovered samples the volume cont…
