The establishment of verifiably safe nanotechnology requires the development of assessment tools to identify hazardous nanomaterial properties that could be modified to improve nanomaterial safety. While there is a lot of debate of what constitutes appropriate safety screening methods, one approach is to use the asses…
Metal in the Middle Biphasic reaction mixtures allow the isolation of sensitive products, which can form in one solvent and then shift rapidly into another, protected from side reactions and interfering by-products. However, ensuring that catalysts remain in the proper phase can be challenging, and surfactants added t…
Rubber ferrite composites were prepared by incorporating nickel ferrite in a neoprene rubber matrix. Kinetics of the cure reaction were determined from the rheometric torque values and found to follow first-order kinetics. Analysis of the swelling behavior of the rubber ferrite composites in toluene elucidates the mec…
The corrosion inhibition of aluminum alloy 5083 by an environment friendly compound called (8- Hydroxyquinoline) inacidic and alkaline solutions of pH (2 and 12) respectively were studied using weight loss and polarization techniques.Also to examine the main and combined effects of the inhibitor concentration, pH, and…
Soda liquid waste is produced in Solvay Process. It creates a very big problem for nature. Therefore, the intent of this article is for removal of calcium from soda liquid waste containing calcium chloride. The soda liquid waste was obtained from Mersin Soda Joint Stock Company in Turkey. The soda liquid waste was rea…
The surface potentials and effective dipole moments of alpha-helical amphiphilic diblock copolypeptides during monolayer compression at the air-water interface are reported. Amphiphilic diblock copolypeptides (PLGA-b-PMLGSLGs) of poly(alpha-L-glutamic acid) (PLGA) and poly(gamma-methyl-L-glutamate-ran-gamma-stearyl-L-…
Bi 2 O 3 doped scandia stabilized zirconia systems have shown promise for use as electrolytes in intermediate temperature solid oxide fuel cells (IT-SOFC's). Sintering properties, crystal phase transformation, and electrical conductivity of the Bi2O3 doped Sc2O3–ZrO2 systems were investigated. The effect of Bi2O3 dopi…
Ion implantation experiments of indium (In) into sputter-deposited undoped ZnO films were carried out to control the resistivity for n+-ZnO layers of electronic device. Improvement of ZnO crystallinity after the ion implantation was revealed by x-ray diffraction patterns including a shift of lattice parameter, enhance…
Thermal emissivity of nuclear graphite was measured with its oxidation degree. Commercial nuclear graphites (IG-110, PECA, IG-430, and NBG-18) have been used as samples. Concave on graphites surface increased as its oxidation degree increased, and R value (Id/Ig) of the graphites decreased as the oxidation degree incr…
Discontinuities in elastic constants are detected at the superconducting transition of layered organic conductors $\ensuremath{\kappa}\text{\ensuremath{-}}{(\text{BEDT-TTF})}_{2}\text{X}$ by longitudinal and transverse ultrasonic velocity measurements. Symmetry arguments show that discontinuities in shear elastic cons…
The influence of pre-adsorbed hydrogen on the adsorption of CO on well-defined PtRu/Ru(0001) surface alloys and the modification of the adsorption properties of both adsorbate species due to coadsorption was studied by a combination of temperature-programmed desorption and infrared spectroscopic measurements. The hydr…
The surface treatment effects of reinforcement filler were investigated based on the dynamic mechanical properties of mutiwalled carbon nanotubes (MWCNTs)/epoxy composites. The as-received MWCNTs(R-MWCNTs) were chemically modified by direct oxyfluorination method to improve the dispersibility and adhesiveness with epo…
The rotationally covariant renormalization group equations of motion for the density wave amplitudes in the phase field crystal model are shown to follow from a dynamical equation driven by an effective free energy density that we derive. We show that this free energy can be written purely as a function of the strain…
In this paper, the thermo-reversible sol−gel transition of titanium poly oxo building blocks dispersed in a solution of p-toluene sulfonic acid (PTSH) in isopropanol is reported. The sol formed by the thermo-hydrolysis at 60 °C of titanium tetraisopropoxide (Ti(O i Pr) 4 ) reversibly changes into a gel upon cooling. A…
An instantaneous method for the bromination of bisphenol A has been reported using potassium tribromide for the first time as an efficient brominating agent affording the corresponding tetrabromobisphenol A in a reaction time of only 5−10 min at ambient temperature in high yields (99%) and purity (>99%), free from rea…
The aragonite-specific proteins, Pif97 and Pif80, provide new views on remote control of nacre formation. A chitinous membrane is pinned to matured nacre in certain spots until the onset of nucleation of the next layer. In this model, diffusible low-molecular-weight acidic proteins would fulfill an important role as C…
CoFe 2 O 4 –Pb(Zr 0.53 Ti 0.47 )O 3 (CFO–PZT) multiferroic composite thick films sandwiched by PZT composite films were prepared by sol–gel processing and spin‐coating technique. It is shown that although the deeply buried CoFe 2 O 4 spinel ferrite phase could not be detected in X‐ray diffraction patterns, the stable…
CeScO(3) was synthesized by a two-step synthesis route involving a combustion method followed by vacuum heating at 1100 degrees C in the presence of Zr sponge which acts as an oxygen getter. The compound was characterized by various techniques such as X-ray diffraction (XRD), high temperature XRD, thermogravimetry, di…
Polymer-based composite structures have advantages over other materials. The most important advantage is the higher mechanical properties obtained from the composites when supported by fiber reinforcement. The mechanical and thermal properties of fiber-reinforced composite structures are affected by the amount of fibe…
Two complementary dipyrromethane + dipyrromethanemonocarbinol routes to a meso-substituted 5-isocorrole were investigated. While both routes could afford the identical 5-isocorrole, self-condensation of the different dipyrromethanemonocarbinol precursors could potentially lead to a second porphyrinoid of different str…
