The size or alkyl chain length of cationic surfactants can be used to tailor both the pore morphology and the functionality or oxidation state of cobalt in silica materials.
The novel negative-type photosensitive polyimide precursor to protect ELK for Flip-chip package was developed. High modulus was achieved by the rigid structure of main polymer, and film transparency was achieved to modify the side chain unit by tuning the ratio of particular non-acryloyl groups and acryloyl groups. Th…
This study was conducted to see the effect of a mixture of ZnS nanoparticles and PVA on the properties of nanocomposite PV / ZnS. Mixing is done with the sol-gel method, which dissolve ZnS nanoparticles and PVA with distilled water. Stirring is done through the magnet, with the angular velocity of 500 rpm, and heated…
This paper concerns the ITER project demands to provide the machine reliability and the human safety along and after the ITER operation for making the personnel access inside the ITER bioshield possible. New results are presented for radiation streaming inside the gaps of Diagnostic Equatorial Port Plug (EPP) of ITER…
Formation of a five-membered strong triazole ring to facilitate the highly stable anchoring of LC droplet encapsulated polymer capsules over a patterned substrate.
The first tetratopic pyrimidine-hydrazone (pym-hyz) molecular strands containing terminal hydroxymethyl (L1) and acryloyl (L2) functional groups have been synthesised. L1 was produced by step-wise imine condensation reactions, starting with 6-hydroxymethyl-2-pyridinecarboxaldehyde. L2 was then synthesised through the…
The strength of coke largely depends on the thermoplastic and dilatation behavior of its coal constituents. Therefore, understanding the behaviors that ensure high-strength coke is important. In this study, the combination of blended coal was varied and (in a separate experiment) asphalt pitch (ASP) was added to the b…
In recent years, significant developments have been achieved in the field of tissue engineering. Biopolymers and bioceramics are known to play major role in the construction of artificial organs. Chitosan is one of the biopolymers extensively studied for tissue engineering, drug delivery, and wound healing application…
Polyphosphazene/SiO 2 composite membranes and porous polyphosphazene membranes were prepared and their properties were studied in detail.
This study provides a one-step strategy for preparing DNA–Au hybrids as SERS-active substrates by the simple mixing of DNA and Au colloids.
Slurries of ammonia-borane and functionalized amine-boranes form liquid spent fuels after heating in batch or flow-thru reactors.
Abstract There are many photoaligned azo dyes that can be used for orientation of liquid crystals in various display devices. However, the structure of these compounds needs to be optimized to increase the rate of the process of molecule photoalignment, as well as to spread the application of these compounds. The main…
Titanium dioxide (TiO2) nanotubes are prepared by electrochemical anodization using Ti metal foils under a DC bias of 30 V for 20 h. The electrolyte is a mixture of formamide (FA) and ethylene glycol (EG), which contains NH4F (0.3 wt%) and H2O (2.0 v%). The diameter and wall thickness of the nanotubes decrease with th…
Partial Discharge detection techniques strive to ensure a safe and reliable power network by preventing power failure. In this work, electromagnetic sensing of partial discharge, in air-insulated medium voltage switchgear (Type D24-121114 of Driescher) is considered. The partial discharges are approximated by Gaussian…
Impact damping of Ni–Mn–Ga ferromagnetic shape memory alloy/polyurethane composites was studied by instrumented impact tests. By polymerizing the composite under a magnetic field, the martensitic Ni–Mn–Ga particles were spatially aligned in chains parallel to the field direction with the preferable crystallographic or…
The 0.8Pb(Zr 0.48 Ti 0.52 )O 3 -0.125Pb(Zn 1/3 Nb 2/3 )O 3 -0.075Pb(Mn 1/3 Nb 2/3 )O 3 (PZT-PZN-PMnN) + x wt% CuO piezoelectric ceramics, where x = 0.0, 0.05, 0.075, 0.10, 0.125, 0.150, and 0.175, have been fabricated by the conventional solid-state reaction method and the B-site Oxide mixing technique (BO). The effec…
Due to the nonequivalent sub-lattices and interface hybridization, a size and symmetry-dependent band gap can be opened in graphene induced by g-C 3 N 4 substrates.
The oblique penetration performance of lightweight hybrid-cored sandwich plates are investigated numerically. To compose the hybrid-core, ceramic prisms are inserted into pyramidal metal lattice trusses and fixed using epoxy resin. Three-dimensional finite element simulations are carried out for the hybridcored sandwi…
Herein a high-efficiency controlled release nanosystem for fluoroquinolone hydrochlorides was established by a characteristic vacuum-recrystal loaded process based on small pore mesoporous MCM-41. The system exhibited great drug loading capacity (62.31%), matrix type sustained-release behavior (5 days) and excellent b…
Co-assembly of differently sized and shaped nanoparticles within a polymer matrix can be controlled to form unique nanoparticle heterojunctions.
