Considerably faster rates of high temperature reaction were obtained for the new material synthesised by a soft-chemistry route without the use of alkaline metal dopants, in compar...

Inorganic (inorg) and organic (org) routes with acid (A) and base (B) hydrolyzing agents were utilized to synthesize lithium zirconate (LiZr) nanomaterials. The effect exerted by the nature of hydrolyzing agent and synthesis route on the morphology and structural properties of the samples was st...

Lithium based ceramics (Li2TiO3, Li4SiO4 etc.) in the packed pebble form, used in breeder blankets to breed tritium, are promising candidates for future fusion reactors. Neutron induced trap sites in the ceramic breeder affect the diffusion and inventory of tritium and thereby influence the quan...

Hence, lit...

The valuable metals in the cathode of spent lithium-ion batteries (LIBs) have been recovered by a more simple and efficient process. The cathode was leached directly by citric acid without pretreatment such as immersed in N-methyl-pyrrolidone (NMP) or calcined. The leaching conditions of the con...

Chronic N-methyl-d-aspartate (NMDA) administration to rats may be a model to investigate excitotoxicity mediated by glutamatergic hyperactivity, and lithium has been reported to be neuroprotective. We hypothesized that glutamatergic hyperactivity in chronic NMDA injected rats would cause mitocho...

The waste of lithium ion batteries (LIBs) is the major secondary source of valuable elements such as lithium and cobalt.

During discharge in aprotic Li-O2 batteries, lithium peroxide (Li2O2) can be formed by a surface- or solution-mediated route. In the surface-mediated process, a Li2O2 film is formed electrochemically on the cathode surface, leading to low capacity and rate capability. In contrast, in high donor ...
