An analysis of a culturable corrosive bacterial community in water samples from a cooling tower was performed using traditional cultivation techniques and its identification based on 16S rRNA gene sequence. Seven aerobic bacterial species were identified: Pseudomonas putida ARTYP1, Pseudomonas aeruginosa ARTYP2, Massi…
The mechanoluminescence (ML) of SrAl2O4:Eu(+), Dy(3+) (SAO) has been of particular interest based on the possibility that these materials could be used as nondestructive, reproducible stress (or load) sensors. However, there has been no in-depth study of ML under a cyclic load. It was found that a cyclic load generate…
Zn (1-x) Ga x O thin films (x = 0.01, 0.03, 0.05, 0.07 named as GZO1, GZO2, GZO3, GZO4, respectively) were deposited on glass substrates by RF magnetron sputtering. The crystal structure, electrical, thermoelectric and magneto-thermoelectric properties of GZO films were investigated. It is found that all the GZO films…
In the present work, five new Ni5 clusters employing the versatile 2-pyridylcyanoxime ligand have been synthesized and chemically, structurally, and magnetically characterized. The crystallographic examination of these Ni5 clusters together with those already published in the literature, giving a total number of 14 co…
Polymer layered silicate (PLS) nanocomposites have been prepared with diglycidyl ether of bisphenol-A (DGEBA) epoxy resin as the matrix and organically modified montmorillonite (MMT) as the clay nanofiller. Resin-clay mixtures with different clay contents (zero, two, five and 10 wt%) were cured, both isothermally and…
The formation of core–shell structure plays a very important role in temperature stable BaTiO3‐based dielectric ceramic for multilayer ceramic capacitors applications. In this work, the rare earth Dy modified BaTiO3 dielectric ceramics have been prepared by chemical coating method, which possess high dielectric consta…
Ion exchange of the interlayer carbonate anion of Co(II)/Al(III) layered double hydroxide with dodecylsulfate was conducted by the reaction in aqueous media under hydrothermal conditions. While the hexagonal plate particle shape was retained, the thickness of the plate increased. The ratio of the average particle thic…
The solubility of Fluconazole in pure methanol, ethanol, propan-1-ol, butane-1-ol, chloroform, tetrahydrofuran, and 1,4-dioxane was measured by gravimetric method over a temperature range (298.15 to 323.15) K at atmospheric pressure. The solubility increases nonlinearly with temperature in all seven solvents. The expe…
The non-linear magnetoelectric (ME) response of Metglas/PMN-PT based sandwiched ME laminate composites has been studied for various thicknesses of the magnetostrictive layer. A significant increase in the non-linear ME coefficient under zero direct current bias was observed with a decreased Metglas thickness ratio for…
The process of carbon deposition onto 3d metal surface immersed in aromatic solvents (benzene, toluene, xylene) at ambient conditions was studied for as-prepared magnetic nanoparticles (MNPs) and Fe-based films by thermal analysis, mass spectrometry, X-ray diffraction, X-ray photoelectron spectroscopy, Raman spectrosc…
The electrical properties of epoxy based composites modified by low amounts of graphite oxide, below the conduction threshold, have been investigated. The composites have been prepared without the use of solvents by direct sonication of graphite oxide (GO) powders and of chemically modified and partially reduced GO po…
We performed comparative DFT (B3LYP/Lanl2dz) studies of the structural and electronic properties of bare and NH 3 -, SCH 3 -, and OPH 3 -capped Cd 33 Se 33 and Cd 33 Te 33 quantum dots (QDs). The capping groups were chosen as simple models for capping ligands used broadly in experiments. We explored the effects of the…
The study investigates the effect of increasing NCO/OH molar ratio on the physico-mechanical and thermal properties of isocyanate terminated polyurethane prepolymer. The prepolymer was prepared using methylene diphenyl diisocyanate and difunctional polypropylene glycol. The NCO/OH molar ratio has been varied from 1.2:…
Small-angle X-ray scattering (SAXS) is a powerful technique for studying weak interactions between proteins and their ligands (other proteins, DNA/RNA or small molecules) in solution. SAXS provides knowledge about the equilibrium state, the stoichiometry of binding and association-dissociation processes. The measureme…
Sodium niobate (NaNbO3, or NNO) is known to be antiferroelectric at temperatures between 45 and 753 K. Here we show experimentally the presence of the ferroelectric phase at temperatures between 100 and 830 K in the NNO crystals obtained by top-seeded solution growth. The ferroelectric phase and new phase transitions…
Cartilaginous tissues engineered using mesenchymal stem cells (MSCs) can be leveraged to generate bone in vivo by executing an endochondral program, leading to increased interest in the use of such hypertrophic grafts for the regeneration of osseous defects. During normal skeletogenesis, canals within the developing h…
Combination of two or more drugs has emerged as a promising strategy to elicit synergistic therapeutic responses that can overcome multidrug resistance of cancer cells at various stages of the growth cycle. In the current study, we investigated the efficacy of two drugs, mitoxantrone (MTX) and doxorubicin (DOX), co-en…
The dispersion of silicon quantum dots (Si QDs) in water has not been established as well as that in organic solvents. It is now demonstrated that the excellent dispersion of Si QDs in water with photoluminescence (PL) quantum yields (QYs) comparable to those for hydrophobic Si QDs can be realized by combining the pro…
Förster resonant energy transfer (FRET) between PbS quantum dots (QDs) in assemblies of QDs with a narrow size distribution (quasi-monodispersed), embedded in a porous matrix, is investigated. Analysis of size-selective steady-state and transient photoluminescence (PL) of these assemblies demonstrates the influence of…
The morphotropic phase boundary (MPB) has been utilized extensively in ferroelectrics and recently has attracted interest in ferromagnets [S. Yang, H. Bao, C. Zhou, Y. Wang, X. Ren, Y. Matsushita, Y. Katsuya, M. Tanaka, K. Kobayashi, X. Song, and J. Gao, Phys. Rev. Lett. 104, 197201 (2010); R. Bergstrom, M. Wuttig, J.…
