The paper concerns research on the effect of high sulphur coke on current efficiency, carbon consumption and carbon dusting during aluminium electrolysis. Current efficiency and electrolytic carbon consumption tests have been performed with graphite and prebaked anodes with varying sulphur contents. The tests were car…
Understanding the magnetic anisotropy at ferromagnetic metal/oxide interface is a fundamental and intriguing subject. Here we propose an approach to manipulate the strength of perpendicular magnetic anisotropy (PMA) by varying MgO thickness in the MgO/CoFeB/Ta thin films. We identify that the PMA at the MgO/CoFeB inte…
The electrode processes involving vanadium species were studied at 690–860°C in NaCl-KCl-based melts employing electrochemical stationary and non-stationary methods: galvanostatic commutational, chronoamperometry, chronopotentiometry, linear, cyclic and square-wave voltammetry. At anodic current densities up to 1 A/cm…
Pure zirconium metal is widely used as a construction material in nuclear reactors in the form of alloys such as zircaloy. For nuclear reactor materials, the metal zirconium should have a very low hafnium content of less than 0.01 wt%. So far, there are no efficient processes which dominate the industrial production o…
The corrosion behavior of AISI 316L, 316Ti, and 321 austenitic stainless steels was studied in melts based on a NaCl-KCl equimolar mixture at 750 °C employing spectroscopic, gravimetric and electrochemical methods in addition to chemical and microscopic analysis. Iron, chromium and manganese species constitute the maj…
This paper presents recent developments of alternative anhydrous alkali metal and alkaline earth nitrate and nitrite mixtures with low melting temperatures and high thermal stabilities for concentrating solar power (CSP) applications. First, the known minimum melting temperatures of the relevant binary and ternary sys…
We report on a new method for preparation the magnetocaloric alloy Gd5Si4. By mechanical alloying under argonatmosphere and then melting sample by arc furnace, we produced the Gd5Si4 alloy. The structure and magnetothermalproperties of the alloy have been investigated with the help of powder X-ray diffraction and magn…
Cancer is a leading cause of mortality at global level, with recent advancements in research of anticancer drug therapy and diagnosis resulting in modest impacts on cancer therapy. Multifunctional or theranostic metallic nanoparticles gained attention in recent years as promising therapeutic paradigms, which provide a…
The phase behavior of blends of A‐b‐B and A‐b‐C diblock copolymers with opposite self‐assembly tendencies are studied, where the former exhibits the assembly upon heating and the latter shows the assembly upon cooling. A compressible random‐phase approximation (RPA) theory and a Ginzburg–Landau simulation based on the…
Mixed Fe 2 O 3 - NiO thin films have been prepared by chemical Spray pyrolysis technique onto glass substrate preheated to 450 °C. The thickness of thin films was found to be (400 ±20) nm. XRD measurements reveal that all the film exhibit polycrystalline hexagonal wrutzite with a preferred orientation along (104) plan…
The nuclear track registration technique with pm-355detector used to determine the uranium concentrations for twentyeight samples of soil distributed in seven districts for Al-Durra city in Baghdad governorate with depth (5) cm .The uranium concentration in soil samples measured by bombardment uranium with thermal neu…
The concrete composites play an important role in the field of concrete. The addition of fibers to concrete enhances the strength properties and ductility characteristics. Ferrocement is light weight and versatile material having high cracking, ductility and fatigue resistance and is additionally impermeable to make i…
Here we present a novel method for the fabrication of dual-scale surface topographies in the nano and submicron scale for biomedical applications. The results show that the behavior of fibroblasts and glial cells were significantly altered on the structured surfaces as compared to our control surface. Such surfaces wi…
In this paper, the mechanical and tribological properties of synthesized ortho- and meta-cresol novalac epoxy resin composites have been explored. Three microsize fillers SiC, Al 2 O 3 , and ZnO particulates (10 wt%) have been used as reinforcement for the composites. The dry sliding wear tests were conducted on the p…
The photophysical properties of 5-deazaalloxazine and 1,3-dimethyl-5-deazaalloxazine were studied in different solvents. These compounds have higher values of fluorescence quantum yields and longer fluorescence lifetimes, compared to those obtained for their alloxazine analogs. Electronic structure and S0 -Si transiti…
Upon light irradiation, Fluorophore-cell-penetrating peptide (Fl-CPP) conjugates can disrupt the integrity of biological membranes. This activity can in turn be used to photoinduce the disruption of endocytic organelles and promote the delivery of entrapped macromolecules such as proteins or RNAs into live cells. Rece…
Peptide-based nanoparticles (pep-NPs) are emerging as promising imaging and therapeutic agents against cancer due to their biocompatibility and tunability. Optimized design of the peptide sequence and moderate conjugation of the sequence with extraneous molecules are crucial to the performance of the inherent properti…
Monodisperse iron nanoparticles of size range 5–19 nm with controlled crystallinity and magnetic properties are synthesized via thermal decomposition of iron pentacarbonyl in the presence of an appropriate ligand. Crystalline body-centered cubic iron nanoparticles synthesized in the presence of didodecyldimethylammoni…
For chemical-mechanical polishing of epitaxial gallium nitride (GaN), a two-step experiment method with two kinds of abrasives, aluminum oxide (Al 2 O 3 ) and colloidal silica (SiO 2 ), was put forward. The average material removal rates of GaN by the slurry with Al 2 O 3 and SiO 2 abrasives were 594.79 and 66.88 nm/h…
Multiwalled carbon nanotubes (MWCNT) have a fibrous structure similar to asbestos, raising concern that MWCNT exposure may lead to asbestos-like diseases. Previously we showed that MWCNT translocated from the lung alveoli into the pleural cavity and caused mesothelial proliferation and fibrosis in the visceral pleura.…
