Neurological glutamate receptors are among the most important and intensely studied protein ligand binding systems in humans. They are crucial for the functioning of the central nervous system and involved in a variety of pathologies. Apart from the neurotransmitter glutamate, several artificial, agonistic and antagon…
Results of dilatometric (80–800 K) and DTA (293–1200 K) investigations of borate glasses Li₂B₆O₁₀, LiCsB₆O₁₀, Li₂B₄O₇, LiKB₄O₇, LiCaBO₃ and CaB₄O₇ in temperature range have been presented. Thermal parameters Tg, TD, Tp, Tm and temperature dependences of thermal expansion coefficient α(T) have been determined and analy…
We analyze an approach toward stabilizing high-pressure rocksalt (RS) CdSe phases at atmospheric pressures using a ZnS core–CdSe shell 1 –ZnS shell 2 architecture. The approach exploits the lattice mismatch between ZnS core and CdSe shell 1, which generates bulk stress in the CdSe shell 1 in wurtzite structure, thus d…
We analytically compute the thermal conductivity of anharmonic crystals with self-consistent stochastic reservoirs. We develop an integral representation for the heat current, assume the approximation of discrete times, and in a perturbative analysis that is rigorously supported by a convergent cluster expansion compu…
Nanosheet-derived Hx(Ni1/3Co1/3Mn1/3)O2 was prepared by restacking (Ni1/3Co1/3Mn1/3)O2 nanosheets with large or small lateral sizes and their electrochemical properties in a 1 M KOH aqueous solution; microstructural factors were compared with those of bulk Hx(Ni1/3Co1/3Mn1/3)O2 (HNCM). The electrodes composed of small…
For the first time, a series of second-order NLO poly(arylene-ethynylene)s, in which an isolation chromophore was introduced to enhance the NLO coefficients, were successfully designed and synthesized. Thanks to the isolation chromophore, these polymers demonstrated good NLO activities and optical transparency. To fur…
ZnO nanostructures of rod-like, faceted bar, cup-end bars, and spindle shaped morphologies could be grown by a low power ultrasonic synthesis process. pH of the reaction mixture seems to plays an important role for defining the final morphology of ZnO nanostructures. While the solution pH as low as 7 produces long, un…
In this study new chiral nanostructure poly(amide-imide)s (PAI)s were synthesized via direct polycondensation of different trimellitylimido-amino acid-based diacids and 4,4′-methylenebis(3-chloro-2,6-diethylaniline), using tetra-n-butylammonium bromide and triphenyl phosphite as a green media. The formation of these n…
The nanostructure of SmCo 5 /α-Fe nanocomposites elaborated by high-energy ball milling was investigated using atom probe tomography. This high-resolution technique allowed obtaining in the real space a 3D mapping of the chemical species (Sm, Co, and Fe) on the atomic scale. 3D reconstructions of the nanostructure of…
In this paper, we investigated the influence of strain on anisotropic magnetoresistance (AMR) in La0.67Ca0.33MnO3 (LCMO) films epitaxially grown on BaTiO3(001). For 250-nm-thick LCMO film, the AMR shows a peak near the metal-insulator transition (MIT) temperature, which is similar to that in bulk LCMO. When the thickn…
Our study shows that extrinsic disorder plays a decisive role in shaping inhomogeneities at large length scales in phase separated systems. Epitaxial La5/8-yPryCa3/8MnO3 (y = 0.45) thin films grown on SrTiO3, LaAlO3 and NdGaO3 substrates exhibited comparable biaxial strain while showing markedly dissimilar extrinsic d…
We report the effect of surface plasmons of silver nanowires (AgNWs) on the generation of hot electrons. The AgNWs were deposited on ultra-thin Au/TiO2 Schottky nanodiodes using a spraying method. As surface coverage of the AgNWs on the thin gold film increased, the short-circuit current under illumination increased,…
Cr-doped ZnO thin films have been prepared on silicon (100) substrates by a radio-frequency (RF) magnetron sputtering method. The crystallographic structures, optical, and magnetic properties of the thin films are investigated by means of X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), photoluminescen…
A novel linear low-density polyethylene (LLDPE)/polypropylene (PP) blends were prepared by melt blending with moderate cross-linked LLDPE/PP blend (LLDPE–PP) as compatibilizer, the rheological properties associated with the morphological structure of the LLDPE/PP/LLDPE-PP blends were studied by SEM, capillary rheomete…
Melt compounding is used to mix ethylene-vinyl acetate copolymer (EVA) and multi-walled carbon nanotube (MWCNT). Then the obtained EVA/MWCNT mixtures were foamed using a chemical blowing agent. Without any modification of MWCNT, a significant improvement of the tensile properties was observed for the EVA/MWCNT foams.…
Single crystals of pure and Lanthanum doped L-Alanine Tartrate were grown by slow evaporation method. The cell parameters were determined using single crystal X-ray diffraction method. To improve the physical properties of the LAT crystal, Lanthanum dopant was added by 2 mol%. ICP studies confirm the presence of Lanth…
The role of thermal stresses, understood as stresses introduced by a uniform or nonuniform temperature change in a body which is somehow constrained against expansion or contraction, in metallic materials due to extreme loading conditions is under consideration. The thermomechanical couplings (thermal expansion and th…
The expansion of the electronic industry and the extensive use of electronic equipment in communications, computations, automations, biomedicine, space, and other purposes have led to problems such as electromagnetic interference of electronic devices and health issues. For reasons given above, a demand for protection…
Nitrogen-doped carbon nanotubes (NCNTs) have been catalytically synthesized from five different nitrogen-containing aromatic precursors by injection chemical vapor deposition (CVD) in the temperature range of 550–850 °C. The doped nitrogen mainly exists as pyridinic or graphitic nitrogen with the total content of 2–9…
The effective permittivity of CoFeSiB microwire/rubber composites is investigated in the microwave range of frequencies. As the frequency is varied between 0.3 and 6 GHz with or without magnetic field excitation, we identify a two-peak structure of the permittivity spectra. This spectral feature may be attributed to a…
