The design and construction of a sample holder for in operando X-ray absorption spectroscopy on solid oxide electrodes, like for instance the lanthanum strontium manganite electrodes, is explained. The sample holder is mounted in a test-cell, which is also described together with some preliminary test-results from tem…
We have developed a palm-top size EPMA (electron probe X-ray microanalyzer), operated by 3 V electric battery except for a rotary vacuum pump. The electron beam was generated by a pyroelectric single crystal, LiTaO 3 . A needle was used to make a focused electron beam. The smallest beam size was 100 μm on the sample s…
The results show that the greasy fleece weight varied from 0.3 kg to 2.42 kg with an average of 0.75 kg. The fleece weight decreases according to the animal age. In fact, the factor “age” has a significant effect on the dromedary fleece weight. Average scoured yield was 96% with V% of 1.6%. This indicated that matter…
A new method is presented for the extraction of single-chain form factors and interchain interference functions from a range of small-angle neutron scattering (SANS) experiments on bimodal homopolymer blends. The method requires a minimum of three blends, made up of hydrogenated and deuterated components with matched…
High density of electron trapping in high-$\kappa$intergate dielectric (IGD) materials remains a major concern for planar memory cells with either poly-Si or hybrid floating gates (FGs). In this paper, for the first time, using the ultrafast$I{-}V$measurements, it is demonstrated that a significant portion of the P/E…
The exclusive demand for super quality basic refractory castable in the lining of steel making furnaces for the manufacture of inclusion free steel has posed a real challenge towards its innovative development. The present study demonstrated the formation of a new generation cementless basic refractory castable using…
Vanadium oxide thin films are promising materials for various applications. Much attention has been devoted to thermotropic VO2(M/R) films which exhibit semiconductor-conductor phase transition at 67 °C making them excellent materials for switching applications. Non-thermotropic VO2(B) films are semiconducting and hav…
Polyaniline nanofibers were prepared chemically in both emiraldine base (EB) and emiraldine salt (ES) forms. The composite of polyaniline emiraldine salt with single walled carbon nanotubes (SWCNTs) was developed. Electrochemical sensors based on polyaniline nanofibers and its composite have been developed for the det…
Three cis-Ru(dppm)2XY complexes (XY = C2O4, 1; X = Cl, Y = N3, 2; X = Y = N3, 3) were prepared by reactions of cis-Ru(dppm)2Cl2 with (NH4)2C2O4, a mixture of NaN3 and NaPF6, and only NaN3, respectively, while 3 could also be obtained from further reaction of 2 with NaN3 undergoing a facile chloride abstraction. All co…
Non-destructive testing methods, such as Magnetic Barkhausen Noise method, are widely used on railways for examining the stress state of running railway rails. Detailed information about the morphology of the microstructure features of the rail surface is derived by Scanning Electron Microscopy. Phase composition, har…
Large electric field tunable remanent magnetization and in-plane anisotropy in a Fe65Co35 film was observed in sputtered ferromagnetic/ferroelectric heterostructures. Two stable magnetization directions were established through a 90 degrees transition of the in-plane uniaxial anisotropy of FeCo film under a positive e…
Magnetic force microscope (MFM) tips are prepared by coating Si tips of 4 nm radius with [Co (1 nm)/M(1 nm)]20 (M = Pt, Pd, Ni) multilayer films. An MFM tip prepared by coating 40-nm-thick Co film is employed as a reference tip. The influences of M layer material on the spatial resolution and the switching field of MF…
Adherent cells in culture maintain a polarized state to support movement and intercellular interactions. Nanopodia are thin, elongated, largely F-actin-negative membrane projections in endothelial and cancer cells that can be visualized through TM4SF1 (Transmembrane-4-L-six-family-1) immunofluorescence staining. TM4SF…
Organic dyes are a viable alternative to silicon for energy conversion. Using simulations from first-principles, we show that chemical manipulation is a powerful tool for tuning the optical absorption spectra of a special class of dyes in a way that is convenient for exploitation in dye-sensitized solar cells. Specifi…
The subject of this study is the effect of repeated post-weld heat treatment on valves made of low-carbon steel, ASTM A216WCB. Post-weld heat treatment is a common technique used to alleviate detrimental stresses induced in the vicinity of the weld as a result or the weld process. This investigation was set out to cha…
Thermal stability and thermal decomposition of malonic acid, sodium malonate and its compounds with Mn(II), Fe(II), Co(II), Ni(II), Cu(II) and Zn(II) were investigated employing simultaneous thermogravimetry and differential thermal analysis (TG-DTA), differential scanning calorimetry (DSC) in N 2 and CO 2 atmospheres…
In this study, compounds of hydrated lanthanide malonates were synthesized by precipitation of sodium malonates ion. Quantitative studies of the compounds obtained in the solid state, as well as the thermal behavior of these compounds were performed by thermal analysis (TG-DTA and DSC). Additional complementary studie…
P-glycoprotein (Pgp) overexpression has been shown to be correlated with resistance to chemotherapy in patients with malignant breast tumors. The aim of our study was to investigate the role of technetium-99m-tetrofosmin (99mTc-TF) as a functional imaging agent reflecting Pgp expression in these tumors. We prospective…
The physical adsorption of block copolymers is a simple and reliable approach to functionalize the surface of organic or inorganic nanoparticles. This article presents two novel methods of particle coating with block copolymers that may apply to various aqueous colloidal dispersions. The first method relies on the use…
For certain applications, total internal reflection (TIR) lenses are potentially more effective compared with refractive lenses and reflection mirrors since they permit more light power to go through the optical system. The efficiency of such lenses becomes even more prominent for miniature systems application where l…
