Potential applications of sodium-ion batteries in grid-scale energy storage, portable electronics and electric vehicles have revitalized research interest in these batteries. However, the performance of sodium-ion electrode materials has not been competitive with that of lithium-ion electrode materials. Here we present sodium manganese hexacyanomanganate (Na2MnII[MnII(CN)6]), an open-framework ...

We designed an anisotropic electrode, in which Li(+) ion insertion and diffusion are anisotropic, by controlled growth of TiO2 nanosheets parallel to the surface of graphene paper. The anisotropic electrode gives a gravimetric capacity of 112 mA h g(-1) at an ultra-high rate of 100 C (corresponding to 36 s of charge-discharge), 3 times higher than that of a referenced isotropic electrode. The r...

electrode has been investigated as the electrode substrate for deposition of a thin membrane ion gating polymer called polypyrrole (PPy). The PPy membrane was successfully deposited and its surface morphology studied using scanning electron microscopy. Given the properties of the bucky gel electrode and its ability to conduct ions, this work establishes the first step towards a semi-solid ion-g...

Metformin in its protonated form as metformin hydrochloride is used worldwide an advanced antidiabetic drug for type 2 diabetes. Hyperinsulinemia and insulin resistance of cells are the main causes this disease. For patients with diabetes, (MET) works by improving cell sensitivity to insulin.
 It has been shown that methyl orange (MO) forms ionic associate can be isolated solid suitable cr...

A new, simple, sensitive, low cost and rapid potentiometric method for direct determination of ultra trace amounts of sodium dodecyl sulfate (SDS) with a new DS(-)-selective electrode is reported. The electrode was prepared by electropolymerization of aniline in acidified DS- ion on the surface of a Pt electrode. The cyclic voltammetry (CV) was used for electropolymerization of polyaniline (PA)...

We present a segmented linear surface electrode ion trap design that can be used for various applications in optical clocks and quantum computation based on trapped 171 Yb + ions. Our simulations show calculated depth reach up to several electronvolts the pseudopotential minimum of is located above at distance greater than 80 μm. The described calculations different parameters planar with requi...

Today, Li-ion batteries (LIBs) are the most common rechargeable batteries used in electronic devices. SnO2 with theoretical specific capacity of 782 mAh/g is among the best anode materials for LIBs. In this report, Three-dimensional SnO2 nanowires (NWs) on carbon nanotube (CNT) thin film (SnO2 / CNT) is fabricated using a combination of vacuum filtration and thermal evaporation techniques. The ...

Sodium-ion batteries, representative members of the post-lithium-battery club, are very attractive and promising for large-scale energy storage applications. The increasing technological improvements in sodium-ion batteries (Na-ion batteries) are being driven by the demand for Na-based electrode materials that are resource-abundant, cost-effective, and long lasting. Polyanion-type compounds are...
