Viscoelasticity, dielectric anisotropy, and birefringence in the nematic phase of three four-ring bent-core liquid crystals with an L-shaped molecular frame
(Royal Soc Chemistry, 2013)
Molecular shape is an important factor in determining the material properties of thermotropic liquid crystals (LCs). We synthesized and investigated several LC compounds formed by asymmetrically bent molecules with a rigid ...
Solvent washing with toluene enhances efficiency and increases reproducibility in perovskite solar cells
(Royal Soc Chemistry, 2016)
We report a simple process for reproducibly fabricating perovskite solar cells. We emphasize that the solvent washing technique is the most practical method for successful uniform crystallization so it facilitates highly ...
Reflective light modulator based on epsilon-GaSe crystal
(Optical Soc Amer, 2002)
We report the results of investigating a low-voltage, polarization-insensitive, reflective-type modulator based on an epsilon -GaSe crystal and operated at the 1.960-eV line of a He-Ne laser. We demonstrate that the ...
Interdependence of absorber composition and recombination mechanism in Cu(In,Ga)(Se,S)(2) heterojunction solar cells
(Amer Inst Physics, 2002)
Temperature-dependent current-voltage measurements are used to determine the dominant recombination path in thin-film heterojunction solar cells based on a variety of Cu(In,Ga)(Se,S)(2) alloys. The activation energy of ...
Crystal structure and photoluminescence properties of a new Cd-II coordination polymer catena-poly[bis[4-bromo-2-({[2-(pyrrolidin-1-yl)ethyl]imino}methyl)phenolato-kappa N-3,N ',O]di-mu(3)-chlorido-di-mu(2)-chlorido-bis(methanol-kappa O)tricadmium(II)]
(Int Union Crystallography, 2016)
Schiff base-metal complexes have been used widely as catalysts for many organic reactions, such as ring-opening polymerization and oxidation. In view of the importance of Cd-II coordination polymers and in an effort to ...
Phase states and thermomorphologic, thermotropic, and magnetomorphologic properties of lyotropic mesophases: Sodium lauryl sulphate-water-1-decanol liquid-crystalline system
(Amer Physical Soc, 2010)
Phase states in sodium lauryl sulphate-water-1-decanol lyotropic liquid-crystalline system have been investigated for different temperature ranges. The dependence of triangle phase diagram types, phase boundaries, and ...
Investigation of Thermal Properties of PUF/colored Organoclay Nanocomposites
(Polish Acad Sciences Inst Physics, 2015)
Recently PF resins can be also prepared by the addition of urea because urea accelerates cure process of PF resin, reduces the cost and improves its strength performance. Clays have long been used as inorganic fillers in ...
Conduction Mechanism of an Infrared Emitting Diode: Impedance Spectroscopy and Current-Voltage Analysis
(Maik Nauka/Interperiodica/Springer, 2012)
The bias dependent complex impedance spectra of a conventional GaAs based infrared emitting diode have been studied in the temperature range 150-300 K. It is found that for bias voltages lower than 0.7 V, the device behaves ...
