The electrochemical performance of mesoporous carbon (C)/tin (Sn) anodes in Na-ion and Li-ion batteries is systematically investigated. The mesoporous C/Sn anodes in a Na-ion battery shows similar cycling stability but lower capacity and poorer rate capability than that in a Li-ion battery. The desodiation potentials of Sn anodes are approximately 0.21 V lower than delithiation potentials. The ...

Lithium (Li)-treated patients often develop urinary concentrating defect and polyuria, a condition known as nephrogenic diabetes insipidus (NDI). In a rat model of Li-induced NDI, we studied the effect that sildenafil (Sil), a phosphodiesterase 5 (PDE5) inhibitor, has on renal expression of aquaporin-2 (AQP2), urea transporter UT-A1, Na(+)/H(+) exchanger 3 (NHE3), Na(+)-K(+)-2Cl(-) cotransporte...

agaricus bisporus and agaricus bitorquis are among most favorite mushrooms of the world. mineral contents, proximate composition and fatty acid profile of these mushrooms were determined for evaluation of their dietary value. na, k and li contents were high, while cr, cu, pb, co, zn, mn and ni concentrations were low in both agaricus bisporus and agaricus bitorquis. proximate analysis showed th...

The DO1(18c6)fi (MwLi. Na. K and I 8c6=18-crown-6) complexes have been chosen as the model systems toinvestigate the nature of chemical bonds between alkali metal cations and large mffitidentaie orgmnic ligands.The B3LYP/6-3I+G(d,p) level of calculation has been used for obtaining equilibrium geernetnes and p(r)functions (electron density distributions). By the aid of fundamental physical theor...

We report UV photodissociation (UVPD) and IR-UV double-resonance spectra of 1,2-dimethoxybenzene (DMB) complexes with alkali metal ions, M(+)·DMB (M = Li, Na, K, Rb, and Cs), in a cold, 22-pole ion trap. The UVPD spectrum of the Li(+) complex shows a strong origin band. For the K(+)·DMB, Rb(+)·DMB, and Cs(+)·DMB complexes, the origin band is very weak and low-frequency progressions are much mor...

Carbon-coated olivine NaFePO(4) (C-NaFePO(4)) spherical particles with a uniform diameter of ∼80 nm are obtained by chemical delithiation and subsequent electrochemical sodiation of carbon-coated olivine LiFePO(4) (C-LiFePO(4)), which is synthesized by a solvothermal method. The C-NaFePO(4) electrodes are identical (particle size, particle size distribution, surface coating, and active material...

Fungi possess efficient mechanisms of pH and ion homeostasis, allowing them to grow over a wide range of environmental conditions. In this study, we addressed the role of the pH response transcription factor PacC in salt tolerance of the vascular wilt pathogen Fusarium oxysporum. Loss-of-function pacC(+/-) mutants showed increased sensitivity to Li(+) and Na(+) and accumulated higher levels of ...

The permeation of monovalent cations through the cGMP-gated channel of catfish cone outer segments was examined by measuring permeability and conductance ratios under biionic conditions. For monovalent cations presented on the cytoplasmic side of the channel, the permeability ratios with respect to extracellular Na followed the sequence NH4 > K > Li > Rb = Na > Cs while the conductance ratios a...

Agaricus bisporus and Agaricus bitorquis are among most favorite mushrooms of the world. Mineral contents, proximate composition and fatty acid profile of these mushrooms were determined for evaluation of their dietary value. Na, K and Li contents were high, while Cr, Cu, Pb, Co, Zn, Mn and Ni concentrations were low in both Agaricus bisporus and Agaricus bitorquis. Proximate analysis showe...
