CaCu3Ru4−xMnxO12 bulks with various substitution amounts x and sintering additive CuO (20 vol.%) were prepared, and the influence of x on the electrical conductivity in a wide temperature range (8–900 K) was investigated. Microstructural observations showed an enhancement of bulk densification upon Mn substitution. Although the resistivity increased with increasing x, the resistivity was as low...

MIn2S4 (M = Mn, Cd, Mg) spinels were investigated by Raman scattering spectroscopy under hydrostatic pressure up to 20 GPa. These compounds were found to undergo a reversible phase transition to a Raman-inactive defect NaCl-type structure. Transition pressures of 7.2, 9.3, and 12 GPa were found for M = Mn, Cd, and Mg, respectively. From the analysis of the pressure behaviour of Raman-active mod...

One of the ways to waste energy in buildings is wasting it from the walls. For this reason, insulating materials are used to prevent the loss of energy in buildings. Typically, common insulations are high thickness and thin coatings are used less. The purpose of this research is to introduce nanocomposite thin polymer coatings and its effect on thermal conductivity. For achieving this, chemical...

The effect of salinity and calcium levels on water flows and on hydraulic parameters of individual cortical cells of excised roots of young maize (Zea mays L. cv Halamish) plants have been measured using the cell pressure probe. Maize seedlings were grown in one-third strength Hoagland solution modified by additions of NaCl and/or extra calcium so that the seedlings received one of four treatme...

‘‘In situ’’ conductivity measurements on Al-Pd-Mn quasicrystals have been combined with synchrotron x-ray-diffraction experiments for studying its behavior during phase transformations. In order to confidently reduce the possible contribution to the conductivity of defects and grain boundaries, single-crystal samples have been annealed in situ under UHV conditions. This combined experiment allo...

Salt stress is known to reduce root hydraulic conductivity and growth. To examine a concomitant regulation of aquaporins, the expression of the maize MIP gene family in response to NaCl was analysed by DNA array hybridization. Plants responded differentially to 100 versus 200 mM NaCl treatments. Leaf water content was reduced rapidly and persistently after the application of 200 mM NaCl in cont...

The method of solute permeability coefficient and solute fluxes appointment for the membrane, based on monitoring of changes of conductivity of electrolyte solutions was presented. It was stated that during mechanical stirring of solutions the coefficient of NaCl permeability for microbial cellulose membrane (Biofill) did not depend on configuration of the membrane system and concentrations of ...

The effect of salt and drought stress at the water potentials of-2, -4,-6and -8 bars induced by NaCl and PEG 6000 (Polyethylene glycol 6000) each, on germination and early seedling growth, were investigated for two varieties (PU-19 and Type-9). Electrical conductivity (EC) value of the NaCl solutions were 4.5, 8.8, 12.7 and 16.3 dS m(-1). Germination percentage, root and shoot length, and seedl...

In this research, novel conductive nanocomposites containing urethane acrylate (UA) andpolyaniline/copper (II) oxide nanocomposites (PANi-CuO) were synthesized. At firstpolyaniline/CuO nanocomposites with different amount of CuOnanoparticleswere prepared bychemical oxidationpolymerization of aniline using ammonium peroxydisulfate as an oxidizingagent. Afterward, UA-PANi-...
