Despite graphene's long list of exceptional electronic properties and many theoretical predictions regarding the possibility of superconductivity in graphene, its direct and unambiguous experimental observation has not been achieved. We searched for superconductivity in weakly interacting, metal decorated graphene crystals assembled into so-called graphene laminates, consisting of well separate...

Nitrogen-doped graphene nanoribbon aerogels (N-GNRAs) are fabricated through the self-assembly of graphene oxide nanoribbons (GONRs) combined with a thermal annealing process. Amino-groups are grafted to the surface of graphene nanoribbons (GNRs) by an epoxy ring-opening reaction. High nitrogen doping level (7.6 atm% as confirmed by elemental analysis) is achieved during thermal treatment resul...

in the present study, the interactions of three different lithium species li+, li3+ and ch3li with several different sites of the most stable tautomers of dna nucleo-bases are presented. this investigation is based on the results of thermochemical properties, quantum theory of atoms in molecules (qtaim) and natural bond orbital (nbo) analysis, obtained at b3lyp/6-311++g(d,p) level of theory. th...

Transition metal phosphides as ideal anodes have been attracted a large number of interests due to their excellent performance for lithium-ion batteries. Nevertheless, CoMoP2 materials were rarely reported battery anode materials. Thereupon, excavate ability in LIBs, sandwich-like architecture was employed material, which heterostructured and MoP nanoparticles coated on N, P co-doped carbon mat...

These experiments examined the effects of pre-test intra dorsal hippocampus (intra-CA1) administration of GABAA receptor agonist and antagonist, muscimol and bicuculline respectively, on state-dependent learning induced by lithium. Male NMRI mice were trained in a one-trial step-down inhibitory avoidance task, and immediately after training they received IP injections of either saline (10 mL/kg...

Despite great technological interest in nanostructured zinc oxide (ZnO) for a large variety of applications, such as lightemitting diodes, gas sensors, or dye-sensitized solar cells, their investigation as lithium-ion anode materials has been reported rather scarcely to date. In fact, although a theoretical specific capacity of about 988 mAhg@1 (if the reaction ZnO+ 3Li+3e$LiZn+Li2O is consider...

The Li1.2Mn0.54−xNbxCo0.13Ni0.13O2−6xF6x (x = 0, 0.01, 0.03, 0.05) is prepared by traditional solid-phase method, and the Nb and F ions are successfully doped into Mn and O sites of layered materials Li1.2Mn0.54Co0.13Ni0.13O2, respectively. The incorporating Nb ion in Mn site can effectively restrain the migration of transition metal ions during long-term cycling, and keep the stability of the ...

The incorporation of transition metals (TMs) such as Co, Fe, and Mn into SnO2 substantially improves the reversibility conversion alloying reaction when used a negative electrode active material in lithium-ion batteries. Moreover, it was shown that specific benefits different TM dopants can be combined introducing more than one dopant lattice. Herein, careful characterization Co co-doped via tr...
