Abstract Degradation behavior of ZnO‐glass fiber‐unsaturated polyester composite under exposure to a metal halide lamp is investigated by means of DSC and FTIR. The FTIR results show that the UV photons can increase the carbonyl group on the surface, but ZnO can decrease the carbonyl content and further contribute to…
Abstract A new miniature mixer has been developed to monitor and optimize the preparation protocol of various polymeric compounds and blend systems. The effect of mixing time and other basic processing parameters on the shear and extensional rheological properties of said compounds and blends is examined to understand…
Based on the conservation of complex power technique, the authors demonstrate theoretically that electromagnetic waves can be squeezed and tunnelled through very small circular channel waveguides at cut-off frequency, which mimics the response of epsilon-near-zero (ENZ) materials. Owing to the infinite phase velocity…

Turn on the light: We have designed a light-responsive bridged nucleic acid (BNA) with a photolabile group at the bridged structure that can change its affinity for a complementary single-stranded RNA (ssRNA) in two stages. Oligonucleotides containing light-responsive BNA lose their binding affinity for complementary…
An earlier proposed strategy to orient two merocyanine dyes in the desirable head-to-tail parallel fashion through multiple hydrogen bonds has been examined by molecular dynamics simulations and quantum chemical calculations. Two different merocyanine dyes dissolved in chloroform solution under various conditions are…
Abstract Attempts were made to study rheology and morphology of high impact polystyrene/polyethylene (HIPS/PE) blends. The Effect of compatibilization using styrene‐butadiene‐styrene copolymer (SBS) and styrene‐ethylene‐butylene‐styrene copolymer (SEBS) on their properties was also studied. The results of linear visco…
The shape, structure, and orientation of rubbing-aligned cadmium selenide (CdSe) nanorods on polymer coated glass substrates have been studied using transmission electron microscopy (TEM) and grazing incidence X-ray scattering combined with computer simulations. The nanorods are found to be of wurtzite structure and h…
A soft surface-enhanced Raman scattering (SERS) substrate was fabricated based on a three-dimensional (3D) structure of biocompatible end-tethered poly( l -lysine) (“t-PLL”) with a brushlike configuration conjugated with silver nanoparticles (Ag NPs) (Ag NP-t-PLL film). The conjugation procedures were carefully adjust…
Recently, several experimental results verified the tunneling effect theory of that the electromagnetic energy can be squeezed through an ultra-narrow channel filled with epsilon-near-zero (ENZ) medium. However, the energy squeezing can be only achieved in a narrow region. Here, we present a full-wave simulation of th…
A systematic approach was developed and applied to the preferential crystallization of a racemic-conglomerate-forming system in our previous work. In this work, we extended and modified the strategy for two typical types of racemic-compound-forming systems, namely, mandelic acid and ketoprofen, taking into account the…
The synthesis of lanthanum phosphates in molten LiCl-KCL eutectic was chosen to address the preliminary treatment of chlorinated wastes containing fission products that are already present in a Li/Cl eutectic. The obtained monazite compound shows interesting properties to be considered as a good candidate to trap lant…
To study long-distance magnetic interactions between exchange-coupled metal centers and coordinated radical moieties, two new homodimetallic Cu(II) complexes held together by the chelating ligand L(nPr) = N,N,N',N'-tetrakis(N-propyl-2-benzimidazolyl)-2-hydroxy-1,3-diaminopropane and additionally bridged by either a ni…
Based on the phase diagram constructed for water-silk fibroin-LiBr using the osmotic stress method, wet-spinning of osmotically stressed, regenerated Bombyx mori silk fibroin was performed, without the necessity of using expensive or toxic organic solvents. The osmotic stress was applied to prestructure the regenerate…
Abstract Blends of polyamide‐6 (PA6) or postindustry polyamide‐6 (piPA6) and high‐density polyethylene (HDPE) or recycled high‐density polyethylene (rHDPE) were processed in single and twin‐screw extruders. The use of rHDPE in the blends promotes a significant decrease of size domains and improvement in the mechanical…
The reaction of cis-[Fe(III)(cyclam)Cl(2)]Cl with 1 equiv of sodium N-diethyldithiocarbamate, toluene-3,4-dithiolate, and maleonitriledithiolate in methanol in the presence of triethylamine afforded the cations [Fe(III)(cyclam)(Et(2)dtc)](2+) (1), [Fe(III)(cyclam)(tdt)](+) (2), and [Fe(III)(cyclam)(mnt)](+) (3), which…
First-principles calculations on the electronic, transport, and lattice vibrational behaviors of Si nanowires (SiNWs) are performed to reveal the origin of the high thermoelectric performance in SiNWs. Our results show that the power factor ( S 2 σ) of SiNWs deviate only slightly from those of bulk Si originating from…
We report the use of polyaniline nanofiber−metal salt composites for the detection of arsine gas (AsH 3 ) using the resistance change of the materials. Aqueous dispersions of polyaniline nanofibers facilitate the preparation of metal salt/polyaniline nanofiber composites with the use of water-soluble inorganics. Vario…
Abstract Photoswitchable DNA‐binding ligands should be useful for controlling diverse biological functions involving DNA and reversible assembly of DNA‐based nanostructures. In work directed towards the development of photoswitchable ligands with various sequence specificities, we have elaborated an efficient synthesi…
Zn(x)Cd(1-x)Se/C core/shell nanocrystals with 31-39 nm semiconducting core and 11-25 nm carbon shell were synthesized from solid state precursors in large scale amounts. A mixture of spherical and tripod nanostructures were obtained only in the one-step reaction (ZC3), where the Zn- and Cd-precursors were reacted simu…
