Lithium nitride, Li3N, is one of the best Li conductors at room temperature. Unfortunately, its application as electrolyte in batteries is limited due to the low decomposition potential of only 0.45 V. Nevertheless, diffusion in Li3N was studied by many groups and various techniques (see [1-3] and references therein) which predestines it to act as a model system for the establishment of new tec...
Dercum's disease (adiposis dolorosa) is characterised by adiposity and chronic pain in the adipose tissue. It has been proposed that conditions encompassing chronic pain have altered concentrations of neuropeptides involved in pain transmission. The aim of this investigation was to examine whether patients with Dercum's disease have abnormal concentrations of different neuropeptides. In cerebro...
Lithium metal oxide nanoparticles were synthesized by induction thermal plasma. Four different systems-Li-Mn, Li-Cr, Li-Co, and Li-Ni-were compared to understand formation mechanism of Li-Me oxide nanoparticles in thermal plasma process. Analyses of X-ray diffractometry and electron microscopy showed that Li-Me oxide nanoparticles were successfully synthesized in Li-Mn, Li-Cr, and Li-Co systems...
The diversity of nicotinic ACh receptor (AChR) expression in the chick lateral spiriform nucleus (SpL) was assessed using subunit-specific monoclonal antibodies (mAbs) and laser scanning confocal microscopy. The late embryonic SpL was immunoreactive for mAbs against the alpha 2, alpha 5, alpha 7, alpha 8, and beta 2 AChR subunits. Distinct neuronal cell classes were determined using pair-wise s...
Alkali metal ion batteries, and in particular Li-ion have become a key technology for current future energy storage. The inherent complexity of batteries their components make computational approaches on different length time scales indispensable gaining atomistic insights as well predicting new materials with improved properties. In this comprehensive review, the theoretical concepts that unde...
Liver-intestine cadherin (LI-cadherin) represents a novel type of cadherin within the cadherin superfamily that comprises seven cadherin repeats and a short cytoplasmic domain. In this study, we first examined LI-cadherin expression immunohistochemically in 34 specimens of human intrahepatic cholangiocarcinoma (ICC). LI-cadherin expression was positive (defined as positivity in > or = 10% of ce...
Catecholaminergic depletion within the prelimbic medial prefrontal cortex enhances latent inhibition
Latent inhibition (LI) refers to the reduction in conditioning to a stimulus that has received repeated non-reinforced pre-exposure. Investigations into the neural substrates of LI have focused on the nucleus accumbens (NAc) and its inputs from the hippocampal formation and adjacent cortical areas. Previous work has suggested that lesions to the medial prefrontal cortex (mPFC), another major so...
Motivated by the recent report of a high Li “plateau” extending to low metallicities in Galactic halo stars, we study the energetics of an early production of Li through the interaction of energetic particles with the interstellar medium. We then explore the potential of various candidate sources of pre-galactic energetic particles and show that, in general, they fail to satisfy the observation...
The use of lithium (Li) metal anodes has been reconsidered because of the necessity for a higher energy density in secondary batteries. However, Li metal anodes suffer from 'dead' Li formation and surface deactivation which consequently form a porous layer of redundant Li aggregates. In this work, a fibrous metal felt (FMF) as a three-dimensional conductive interlayer was introduced between the...
Although red giants deplete lithium on their surfaces, some giants are Li-rich. Intermediate-mass asymptotic giant branch (AGB) stars can generate Li through the Cameron–Fowler conveyor, but the existence of Li-rich, low-mass red giant branch (RGB) stars is puzzling. Globular clusters are the best sites to examine this phenomenon because it is straightforward to determine membership in the clus...
