TiO 2 nanoparticles with 2 and 4 % Cu are synthesized by sol–gel method. The crystalline phase and size of the nanoparticles are investigated with X-ray diffraction and transmission electron microscope. Cu-doped TiO 2 has an extended absorption ranging from UV to visible region. Doping of Cu disturbs the arrangement o…
Successful treatment of brain tumors such as glioblastoma multiforme (GBM) is limited in large part by the cumulative dose of Radiation Therapy (RT) that can be safely given and the blood-brain barrier (BBB), which limits the delivery of systemic anticancer agents into tumor tissue. Consequently, the overall prognosis…
Halloysite clay nanotubes loaded with corrosion inhibitors benzotriazole (BTA), 2-mercaptobenzimidazole (MBI), and 2-mercaptobenzothiazole (MBT) were used as additives in self-healing composite paint coating of copper. These inhibitors form protective films on the metal surface and mitigate corrosion. Mechanisms invol…
We report large-scale computer simulations of the hard-disk system at high densities in the region of the melting transition. Our simulations reproduce the equation of state, previously obtained using the event-chain Monte Carlo algorithm, with a massively parallel implementation of the local Monte Carlo method and wi…
An exchange gap in the Dirac surface states of a topological insulator (TI) is necessary for observing the predicted unique features such as the topological magnetoelectric effect as well as to confine Majorana fermions. We experimentally demonstrate proximity-induced ferromagnetism in a TI, combining a ferromagnetic…
A transfer matrix method is developed for optical calculations of non-interacting graphene layers. Within the framework of this method, optical properties such as reflection, transmission and absorption for single-, double- and multi-layer graphene are studied. We also apply the method to structures consisting of peri…
Developing a synthetic methodology for the fabrication of hierarchically porous metal-organic monoliths that feature high surface area, low density and tunable porosity is imperative for mass transfer applications, including bulky molecule capture, heterogeneous catalysis and drug delivery. Here we report a versatile…
We have developed Fe3O4 magnetic nanoparticles/reduced graphene oxide nanosheets modified glassy carbon (Fe3O4/r-GO/GC) electrode as a novel system for the preparation of electrochemical sensing platform. Decorating Fe3O4 nanoparticles on graphene sheets was performed via a facile one-step chemical reaction strategy,…
Cross-linked rather than non-covalently bonded graphitic carbon nitride (g-C3 N4 )/reduced graphene oxide (rGO) nanocomposites with tunable band structures have been successfully fabricated by thermal treatment of a mixture of cyanamide and graphene oxide with different weight ratios. The experimental results indicate…
Bis(thiosemicarbazone)acenaphthenequinon (LH 6 ) was synthesized in one step from acenaphthoquinone and thiosemicarbazone. The diamine (LH 6 ) was characterized by FT-IR, 1 H NMR and melting point. diamine was used to prepare novel polyamides. The low temperature solution polycondensation of ligand with aromatic ring.…
A hollow cathode sputter source is developed to trace the production of carbon clusters and study the influence of discharge current and argon gas pressure on cluster production using an optical emission spectroscopic technique. Optical emission spectra from the hollow cathode source reveal the production of the C2 Sw…
The goal of this research is to adapt a direct test to estimate the residual flexural properties of individual framing members for post-fire evaluations. The adaptation incorporates partial-composite action with an aluminum stock and a cycle of increasing load tests that are applied gradually. The evaluations of the m…
Polypyrrole nanoparticles were synthesized by chemical polymerization method using ammonium persulphate as an oxidant. The synthesized polypyrrole nanoparticles were characterized by FT-IR, UV-Visible, FESEM and CV. The structure of polypyrrole nanoparticles were confirmed by FT-IR spectroscopy. The UV-Vis spectra of…
Plasma‐enhanced chemical vapor deposition was employed to fabricate hydrogenated amorphous carbon (a‐C:H) films and fluorine‐doped hydrogenated amorphous (a‐C:H:F) carbon films. For comparison purpose, the a‐C:H films were treated with CF 4 plasma. The bonding structure and tribological behavior of the films were inve…
Abstract Polyaniline (PANI) is one of the most studied conductive polymer with several unique properties and good conductivity. In this study it was aimed to prepare Polyaniline (PANI)/Hexagonal boron nitride (h-BN) composites. Chemical structures of the composites were characterized by FTIR analysis. Thermal properti…
The inhibition efficiency (IE) of an aqueous extract of the(Curcuma longa L.) plant material rhizome powder has been used as a corrosion inhibitor in controlling corrosion of carbon steel in sea water, by the weight-loss study, in the absence and presence of Zn 2+ . The main constituent of this plant extract is curcum…
Four experimental fuel assemblies (EFAs) containing 9Cr-ODS steel cladding fuel pins were previously irradiated in the BOR-60 to demonstrate the in-reactor performance of 9Cr-ODS steel for use as fuel cladding tubes. One of the EFAs achieved the best data, a peak burn-up of 11.9at% and a neutron dose of 51 dpa, withou…
Polyethylene degradation over alumina and tungstophosphoric acid (TPA) containing ordered mesoporous catalysts was studied in a semibatch reactor. In the noncatalytic degradation reaction, selectivity of C 3 and C 4 hydrocarbons was quite high. However, significant ethylene and C 4 hydrocarbon selectivity was observed…
Equivalent circuit models are presented for the propagation of noise in one-dimensional negative-index metamaterials based on split-ring resonators (SRRs) and rods. The SRRs are modeled as lossy lumped-element $L$-$C$ resonators, whose reactive components provide the effect of a negative relative permeability over a r…
Partially biodegradable green composites have been made by incorporating vakka fibers as reinforcement in the polyester matrix. The influence of fiber content and temperature on thermal conductivity, specific heat and thermal diffusivity of composites was investigated. The transverse thermal conductivity of unidirecti…
