Objective(s):Theneuroprotective effect of lithium has been attributed to its therapeutic action. However, the role of glial cells particularly astrocytes, and the possible interactions between neurons and astrocytes in neuroprotective effects of lithium have been disregarded. Thus, the aim of this study was to evaluate the direct effects of lithium on brain derived neurotrophic factor (BDNF) an...

The pure rotational spectrum of LiS …X 2 P i † has been recorded in the v ˆ 0 and v ˆ 1 states in the region 130±540 GHz using millimeter/sub-millimeter direct absorption methods. This radical was synthesized from lithium vapor and CS 2 in a DC discharge. Transitions arising from the two orbit components were measured, both which exhibited lambda-doubling and, for the X ˆ 1=2 ladder, hyper®ne i...

When testing the electrochemical performance of metal oxide anode for lithium-ion batteries (LIBs), binder played important role on the electrochemical performance. Which binder was more suitable for preparing transition metal oxides anodes of LIBs has not been systematically researched. Herein, five different binders such as polyvinylidene fluoride (PVDF) HSV900, PVDF 301F, PVDF Solvay5130, th...

A series of molecules, based on the smallest carbon cluster with one planar tetracoordinate carbon atom, C5(2-), are presented. To gain a better understanding about which electronic factors contribute to their stabilization, several global reactivity indexes, molecular scalar fields, and magnetic responses were calculated. The optimized bond lengths and the topological analysis of the electron ...

Sulfur is a promising cathode material for lithium-sulfur batteries because of its high theoretical capacity (1,675 mA h g(-1)); however, its low electrical conductivity and the instability of sulfur-based electrodes limit its practical application. Here we report a facile in situ method for preparing three-dimensional porous graphitic carbon composites containing sulfur nanoparticles (3D S@PGC...

Recent dissociative recombination (DR) experiments have investigated the role of the parent ion’s structure, bonding and charge centre on the DR process. For examples, in the DR of the H+5 and D5O + 2 [1] cluster ions, the dominant product channels greatly reflect the structure of the parent ion, H+3 ·H2, and D2O·D ·D2O[1] respectively, and the question arises on the role played by the ”neutral...

Small carbon clusters metallized with Li were studied within a hybrid density functional approach with generalized gradient correction. Structures of the ground state and several excited states associated with different isomers and multiplicities were systematically calculated for CxLiy with x = 1–3 and y = 1–5. The most stable isomers are either linear or planar in the ground state. Three-dime...

Cation-π interactions were systematically investigated for the adsorption of H+ and alkali metal cations M+ to pyrene by means of Møller-Plesset perturbation theory (MP2) and density functional theory (DFT). The main aims were to determine the preferred adsorption sites and how the microhydration shell influences the adsorption process. The preferred adsorption sites were characterized in terms...

Surface acoustic waves (SAWs) are appealing as a means to manipulate fluids within lab-on-a-chip systems. However, current acoustofluidic devices almost universally rely on elastomeric materials, especially PDMS, that are inherently ill-suited for conveyance of elastic energy due to their strong attenuation properties. Here, we explore the use of a low-viscosity UV epoxy resin for room temperat...
