The modeling of transport behavior of charged particles carried out in our laboratory is based on classical continuum electro kinetic theory. It is applied to a variety of systems from small electrolyte ions to macromolecules including peptides, DNA and nanoparticles. Systems range from weakly charged particles to highly charged ones. Transport properties studied include conductance, electropho...

Despite over a century of study and decades of intensive research, few fuel cell products have appeared on the market. The major inhibitor to mass commercialisation is cost. H2/air alkaline fuel cells (AFCs) containing KOH(aq) electrolyte promise the lowest cost devices, with the ability to use non-Pt catalysts. The fundamental problem with AFCs is that the KOH(aq) electrolyte reacts with CO2 (...

Solid polymer electrolytes (SPEs) could play a major role in the transition to safer and high-energy-density potassium-based batteries. However, most polymeric K-ion are based on fluorine-containing anions flammable organic solvents, whose safety is nowadays question. Herein, we report facile solvent-free synthesis of series several poly(ethylene oxide) (PEO)-based SPE solid solutions with KBPh...

The formation of lithiophobic inorganic solid electrolyte interphase (SEI) on Li anode and cathode (CEI) the is beneficial for high-voltage metal batteries. However, in most liquid electrolytes, decomposition organic solvents inevitably forms components SEI CEI. In addition, often pose substantial safety risks due to their high volatility flammability. Herein, an organic-solvent-free eutectic b...

Lithium metal is the ultimate anode choice for high energy density rechargeable lithium batteries. However, it suffers from inferior electrochemical performance and safety issues due to its high reactivity and the growth of lithium dendrites. It has long been desired to develop a materials coating on Li metal, which is pinhole-free, mechanically robust without fracture during Li metal depositio...

Electric detection using a nanocomponent may lead to platforms for rapid and simple biosensing. Sensors composed of nanotips or nanodots have been described for highly sensitive amperometry enabled by confined geometry. However, both fabrication and use of nanostructured sensors remain challenging. This paper describes a dendritic nanotip used as an amperometric biosensor for highly sensitive d...

Hollow nitrogen-doped carbon spheres (HNCSs) were prepared by a facile method as non-precious catalysts for the oxygen reduction reaction (ORR). The HNCS catalysts exhibited ORR activity comparable with a commercial Pt/C catalyst and superior stability in alkaline electrolyte medium.
