Angstrom‐Scale Confined Ion Sieve and Accelerator for Efficient Aqueous Zinc Batteries

Advanced Materials, EarlyView.
An angstrom‐scale confined ion accelerator strategy is proposed for ultra‐stable aqueous Zn anodes. Selective and precise transport of hydrated Zn(H2O)62+, Zn2+ cations, H2O molecules, and SO42− anions is achieved by in‐plane atomic Ti vacancies and angstrom‐scale interlayer free spacing within the Ti0.87O2 interfacial layer, leading to homogeneous Zn ...

Adsorptive stripping voltammetry of vitamin B12.

BUNSEKI KAGAKU, 1994
Vitamin B12 yields a polarographic catalytic wave at ca.-1.6 V vs. SCE. Vitamin B12 in river-water samples was determined by adsorptive stripping voltammetry in order to use this catalytic wave. The supporting electrolyte used was 0.01 M Na2HPO4+0.01 M NaH2PO4. A preconcentration potential of -1.2 V was applied for 5 min.

Adsorption‐Engineered Hydrocarbon Ionomers for Durable Proton‐Exchange Membrane Fuel Cells

Advanced Materials, EarlyView.
Hydrocarbon ionomers suffer from oxidation‐driven interfacial degradation in PEM fuel cell cathodes, leading to catalyst instability. Here, adsorption‐engineered poly(fluorene) ionomers decouple interfacial anchoring from oxidative degradation, enabling strong catalyst–ionomer interactions while resisting electrochemical oxidation.

Determination of Mg (II) in Biodiesel by Adsorptive Stripping Voltammetry at a Mercury Film Electrode in the Presence of Sodium Thiopentone

International Journal of Electrochemical Science, 2013
A mercury film electrode was used to determine Mg (II) in biodiesel by adsorptive stripping voltammetry in presence of sodium thiopentone. A linear response was obtained for Mg (II) in the concentration range of 6.0 × 10-7 to 7.0 × 10-6 mol L-1 for ...

Sub‐Nanometer Cobalt on Tungsten Titanium Carbide MXene (W2TiC2Tx): An Electrocatalyst for Highly Efficient and Stable Alkaline Hydrogen Evolution at Industrial‐Scale Current Density

Advanced Materials, EarlyView.
A novel W2TiC2Tx MXene prepared through a MAX‐phase route supports sub‐nanometer Co for highly efficient alkaline hydrogen evolution. Strong Co–W interfacial interactions optimize hydrogen adsorption and catalytic activity, enabling low overpotentials of 63 mV at 10 mA cm−2, small Tafel slope of 44.3 mV dec−1, and exceptional durability at industrially
