Molecular imaging (MI) is an in vivo assessment of characterization and quantitatively measurement of biological processes at the molecular level. Determination of pathologies of malfunctioned tissues without invasive biopsies or surgical procedures, early detection, monitoring of treatment process and visualization o…
We report on a method and apparatus for the determination of the three-dimensional electronic resistance of proton-exchange membrane fuel cell porous transport layers (PTLs) as a function of compression. Attention is given to the anisotropic nature of the fiber-based materials; between through- and in-plane directions…
Present study performs excess energy values, activity coefficients and partial free energy associated with the quinary Fe-Cr-Ni-Mg-O, quaternary Au-In-Sn-Zn and ternary Pb-Au-Bi liquid alloys, based on published binary thermodynamic descriptions and Chou’s model for extension into higher order systems. Using Kohler, M…
A ruthenium polypyridyl dye containing a hexasulfanyl-styryl modified bipyridyl group as ancillary ligand, coded TG6, is investigated as a sensitizer for ZnO-based dye-sensitized solar cells (DSSCs). The advantages of this dye are a broad wavelength absorption spectrum, a large loading in ZnO photoelectrodes, a signif…
Abstract The Integrated Data Collection Analysis (IDCA) program has conducted a proficiency study for Small‐Scale Safety and Thermal (SSST) testing of homemade explosives (HMEs). Described here is a comparison of the Alleghany Ballistic Laboratory (ABL) friction data and Bundesanstalt für Materialforschung und ‐prüfun…
Abstract An aluminium silo with initial imperfections is analysed. Two types of imperfection are considered. The first one takes the form of local indentations in the shell; their size and range are adopted on the basis of the standard guidelines. The second type is a global imperfection described through the use of i…
This study aims to evaluate the possible ameliorative effect of earthworm (Allolobophora caliginosa) extract (EE) against silicon dioxide nanoparticles (SiNPs)-induced liver injury in male albino rats. The effectiveness of EE was compared with silymarin as a standard hepatoprotective drug. The present work demonstrate…
Extremely low-haze light extraction from organic light-emitting diodes (OLEDs) was achieved by utilizing nanoscale corrugation, which was simply fabricated with plasma treatment and sonication. The haze of the nanoscale corrugation for light extraction (NCLE) corresponds to 0.21% for visible wavelengths, which is comp…
Abstract In this study, adaptive neuro‐fuzzy inference system (ANFIS) and genetic algorithm–artificial neural network (GA‐ANN) models were used to predict inactivation of Salmonella enteritidis by ultrasound. The effect of amplitude levels, duty cycles and irradiation time of ultrasound on inactivation of S. enteritid…
Lipid-based nanoparticles are considered as promising candidates for delivering siRNA into the cytoplasm of targeted cells. However, in vivo efficiency of these nanoparticles is critically dependent on formulation strategies of lipid-siRNA complexes. Adsorption of serum proteins to lipid-siRNA complexes and its charge…
The dispersion of metallic nanoparticles within a chalcogenide glass matrix has the potential for many important applications in active and passive optical materials. However, the challenge of particle agglomeration, which can occur during traditional thin film processing, leads to materials with poor performance. Her…
Using modern thin film growth techniques, and performing structural, magnetic, optical and electrical transport measurements on YbN thin films, the authors show that these films are antiferromagnetic and semiconducting, unlike other rare-earth nitrides that are either para- or ferromagnetic.
Magnetic susceptibility and heat capacity measurements are used to infer information about the short-range magnetic order above the N\'eel temperature ${T}_{N}$ and the antiferromagnetically ordered states below ${T}_{N}$ of quasi-one-dimensional (quasi-1D) ${\mathrm{CuSb}}_{2}{\mathrm{O}}_{6},\phantom{\rule{0.16em}{0…
Ternary and amorphous tungsten silicon nitride (W–Si–N) thin films were grown by atomic layer deposition (ALD) using a sequential supply of a new fluorine-free, silylamide-based W metallorganic precursor, bis( tert -butylimido)bis(bis(trimethylsilylamido))tungsten(VI) [W(N t Bu) 2 {N(SiMe 3 ) 2 } 2 ], and H 2 plasma a…
This work reported branching studies in reversible addition‐fragmentation chain transfer (RAFT) miniemulsion copolymerization of styrene and triethylene glycol dimethacrylate (TEGDMA), and control of branching density distribution using a model‐based computer‐programed monomer feeding strategy. Highly branched polysty…
Abstract The optical properties of InGaN/GaN multiple quantum wells (MQWs) have been studied by means of photoluminescence (PL) and time‐resolved photoluminescence (TRPL) spectroscopy. The radiative and nonradiative recombination lifetimes were evaluated as a function of the excitation energy density. The radiative re…
PURPOSE: Cervical cancer is caused by persistent infection with high-risk types of human papillomavirus (HPV). The aim of this study was to investigate the potential of Raman spectroscopy as a stand-alone analytical tool for clinical diagnosis of HPV infection using human cervical fluids. METHOD: A drop-coating deposi…
PURPOSE: To provide a rapid method to reduce the radiofrequency (RF) E-field coupling and consequent heating in long conductors in an interventional MRI (iMRI) setup. METHODS: A driving function for device heating (W) was defined as the integration of the E-field along the direction of the wire and calculated through…
Spherical mesoporous titania modified iron-niobate nanoclusters FNT1 [FexNbxTi1−2xO2−x/2 (x = 0.01)], with relatively small particle size 10 ± 2 nm and SBET 145 m2 g−1 were prepared using a sol–gel method, from the reaction of titanium and niobium tartrate with triethanol amine and ferric nitrate solution. HRTEM of FN…
We investigated the effect of electrolyte additives on an untreated, conventional micro-sized (non-nano) Si electrode prepared with a polyimide (PI) binder (PI-Si electrode). Both additives, vinylene carbonate (VC) and fluoroethylene carbonate (FEC), improved the cycle stability of a PI-Si electrode half-cell. The sol…
