Glycogen synthase kinase 3β (GSK3β) is a ubiquitous serine/threonine kinase that plays a pivotal role in many biological processes. GSK3β catalyzes the transfer of γ-phosphate of ATP to the unique substrate Ser/Thr residues with the assistance of two natural activating cofactors Mg(2+). Interestingly, the biological o…

Lithium chloride aqueous solutions (LiClaq solutions) below 10 mol.% are vitrified by cooling from room temperature to 77 K at 0.3 GPa. We examine the solvent state of the glassy sample and its transformation by heating at 1 atm using low-temperature differential scanning calorimetry and Raman spectroscopy. This exper…

We investigate the spontaneous emission of a two-level atom placed in the vicinity of a plasmonic cloak composed of a coated sphere. In the dipole approximation, we show that the spontaneous emission rate can be reduced to its vacuum value provided the atomic emission frequency lies within the plasmonic cloak frequenc…

We investigate the wicking in granular media by considering layers of grains at the surface of a liquid and discuss the critical contact angle below which spontaneous impregnation takes place. This angle is found to be on the order of 55° for monodisperse layers, significantly smaller than 90°, the threshold value for…

The crystal structure and the thermal and chemical expansion of rhombohedral La 1– x Sr x CoO 3−δ ( x = 0.3, 0.4) perovskite were investigated by in situ high-temperature X-ray diffraction in pure oxygen and nitrogen atmospheres. The crystal structure was confirmed to change from rhombohedral ( R 3̅ c ) to cubic symme…

In this article, we study the electro-optical (EO) properties of the homogeneous aligned nematic liquid crystal (N-LC) doped with cobalt oxide (Co3O4) nanoparticles (NPs). The EO characteristics of Co3O4 doped N-LC are higher performance, indicating lower threshold voltage (1.33 V), faster rising time (1.479 ms), and…

Optical microscopy and spectroscopy of hybrid nanostructures composed of chlorophyll-containing photosynthetic complexes and silver nanowires reveal strong enhancement of fluorescence intensity of chlorophylls bound to the protein. This effect results from interaction between excited states of molecules embedded in th…

Emission pattern of surface-enhanced Raman scattering (SERS) from the junction of single nanoparticle and a metal film was experimentally demonstrated. The presence of a thin metal film enables the excitation of surface plasmon polaritons (SPPs) to greatly improve the excitation efficiency of SERS, which is subsequent…

We have examined the chemical and photochemical properties of molecular oxygen on the (110) surface of rutile TiO 2 at 100 K using electron energy loss spectroscopy (EELS), photon stimulated desorption (PSD), and scanning tunneling microscopy (STM). Oxygen chemisorbs on the TiO 2 (110) surface at 100 K through charge…

Several new calamitic liquid-crystalline (LC) materials with flexible hydrophilic chains, namely either hydroxy groups or ethylene glycol units, or both types together, have been synthesized in order to look for new functional LC materials exhibiting both, thermotropic and lyotropic behaviour. Such materials are of hi…

The enthalpy of formation for 23 metal oxides, which include groups I and II as well as two transition metals (Ti and Ru), are calculated using random phase approximation (RPA). Compared to the PBE xc functional, the RPA reduces the mean absolute error (MAE) per oxygen from 0.44 to 0.15 eV. The calculated deviations f…

Seven-core Ag/Fe sheathed Sr0.6K0.4Fe2As2 (Sr-122) superconducting wires were produced by the ex situ powder-in-tube method. The relationship between the cold-work deformation process and the superconducting properties of the wires was systematically studied. It was found that flat rolling can efficiently increase the…

Abstract Sulfur poisoning behavior of La 0.6 Sr 0.4 Co 0.2 Fe 0.8 O 3–δ (LSCF6428) cathode was investigated at T = 1073 K (800 °C) under 0.1 ppm of SO 2 ‐air mixture gas; the amount of supplied SO 2 was controlled by changing the flow rate. Two stages of the performance degradation were found: a rapid degradation at t…

Magnetocaloric materials with coexisting magnetic phases appear either due to the phase coexistence in first order phase transitions, or due to the development of composites, which are known to enhance the refrigerant capacity and produce table-like magnetocaloric effect. However, interactions between phases are rarel…

We investigate the charge transport mechanism and subgap density of states (DOS) in p-type Cu2O thin-film transistors (TFTs) using the bias and temperature dependence of the drain currents. Among several charge transport mechanisms, the experimental data are well matched with a multiple trapping and release model, whi…

For linear electron-phonon coupling, the Huang-Rhys factor, S, gives the intensity ratio of the one-quantum vibronic transition (0 → 1) to the purely electronic origin transition (0 → 0) in a vibrationally resolved, zero-temperature absorption or emission spectrum. It is often assumed that the overtone to fundamental…
