In this paper, we present the concept of a soluble tubular conjugated polymer (TCP). We report on a fluorescent 5,5'-Bicalixarene-based polymer where the calixarene units are seamlessly incorporated in the conjugated polymeric chain that can respond to a small molecule complexation inside the hydrophobic cavity. In pa…
A series of new 4H-pyran-4-ylidene donor-based chromophores with a thiophene ring in the spacer has been synthesized. The linear and nonlinear optical (NLO) properties of these compounds have been determined and compared with the results of computational calculations. The position of the thiophene ring proved essentia…
We demonstrate substantial enhancement of Raman transitions of organic molecules by nanostructured gold-coated substrates at the excitation wavelength of 785 nm and experimentally study the factors that influence the enhancement. The substrates are fabricated by using a robust and cost-effective nanopatterning techniq…
Photovoltaic properties of Pb0.95La0.05Zr0.54Ti0.46O3 thin film capacitors prepared using solution based method with metal top electrodes having different work functions are investigated in this work. It is shown that by using aluminum, a low work-function metal, as top electrode, the magnitude of photo voltage as wel…
Of interest for both photovoltaic and photodetector applications is the ability of colloidal quantum dot (CQD) devices to provide response further into the infrared than is typical for other solution-processable materials. Here, we present a simple heterojunction diode structure that utilizes the extended infrared abs…
Abstract Poly(butylene succinate)/bamboo fiber (BBF) biocomposites were prepared by melt blending method. Microencapsulated ammonium polyphosphate (MCAPP) was used as flame retardants to prepare flame retardant BBF biocomposites. The thermal degradation and flame retardant properties of BBF biocomposites were investig…
The effect of temperature on the equivalent magnetic noise floor of Metglas-Pb(Zr,Ti)O3 (PZT) laminate magnetoelectric (ME) sensors has been investigated in the temperature range of −50 °C to 50 °C. In detail, the parameters that control the noise floor of ME sensors, such as capacitance, tan δ, and ME charge coeffici…
The spatial correlations of the monomer displacements are studied via molecular-dynamics simulations of a melt of fully flexible, unentangled polymer chains with different length, interacting potential, density, and temperature. Both the scalar and the vector characters of the correlations are considered and their ext…
Interface states density (N SS ) distribution is extracted in Au/ ZnO Schottky diodes. Nanorods of ZnO are grown on silver (Ag) using aqueous chemical growth (ACG) technique. Well aligned hexagonal–shaped vertical nanorods of a mean diameter of 300 - 450 nm and 1.3 -1.9 μm high are revealed in SEM. Gold (Au) Schottky…
We observed micro-scale phase separation in VO2 thin films on TiO2(001) substrates and investigated the relationship between the appearance of metallic domains and the abrupt resistive changes around the phase transition. The resistive changes are interpreted using a combined resistance model of the two phases, and th…
Abstract Banana‐fiber‐reinforced polypropylene nanocomposites were prepared with a melt‐blending technique followed by compression molding. The thermal stability and fire retardancy of the fiber‐reinforced nanocomposites was studied as a function of the variable weight percentages of fibers and nanoclays with both the…
Abstract The effect of the strain rate and draw temperature on the mechanical behavior of ethylene vinyl alcohol (EVOH) and EVOH composites was analyzed. When EVOH is stretched at moderate strain rates, evidence of strain‐induced crystallization and recrystallization was observed. Higher strain rates produced less str…
The nucleation and crystallization of MgO – B 2 O 3 – SiO 2 ( MBS ) glasses with various TiO 2 additions (0–15 wt%) were studied by means of a nonisothermal, thermal analysis technique, X ‐ray diffraction, and electron microscopy. The effect of the TiO 2 on the nucleation rate was determined from the dependence of the…
We report the catalyst-free synthesis of the arrays of core–shell, ultrathin, size-uniform SiC/AlSiC nanowires on the top of a periodic anodic aluminum oxide template. The nanowires were grown using an environmentally friendly, silane-free process by exposing the silicon supported porous alumina template to CH 4 + H 2…
In the present investigation, we have analyzed the influence of naturally occurring negatively charged polysaccharides on the morphology of zinc oxide obtained in low-temperature precipitation experiments. Performing detailed analyses of scanning electron microscopy (SEM) micrographs, we inferred the morphology of ind…
Recently, a shape memory polymer-based self-healing syntactic foam was proposed and tested as a sealant for expansion joints. The key for success is to train the foam by using a two-dimensional (2D) stress condition (compression in the horizontal or traffic direction and tension in the vertical direction) at a tempera…
Abstract The insertion of organometallic molecules into the hollow core of single‐walled carbon nanotubes can drastically change their properties. Using biocompatible standardized suspensions of pristine, opened, and filled nanotubes, a very selective enhancement of the photoluminescence and optical absorption is obse…
Abstract Fire barrier fabrics are expected to play an increasingly important role in complying with existing and proposed soft furnishing flammability regulations in the US. The number of commercial fire blocking technologies is large in order to accommodate the vast requirements of the consumers, manufacturers, and r…
In recent years, cationic polymeric magnetic liposomes have shown greater stability and prolonged circulation half-life over traditional liposomes. Here, we examined the capability of cationic polymeric magnetic liposomes in delivering drugs into the brain under magnetic targeting with paclitaxel as the loaded agent.…
In ferroic materials, the dielectric, piezoelectric, magnetic, and elastic coefficients are significantly affected by the motion of domain walls. This motion can be described as the propagation of a wall across various types and strengths of pinning centers that collectively constitute a force profile or energetic lan…
