We use large-scale molecular dynamics simulations to study the kinetics of the liquid-gas phase separation if the temperature is lowered across the glass transition of the dense phase. We observe a gradual change from phase separated systems at high temperatures to nonequilibrium, gel-like structures that evolve very slowly at low temperatures. The microscopic mechanisms responsible for the coa...

Nanoporous carbon is coated by pure nickel via an electroless plating method. The nanoporous carbon provides a high-surface-area substrate, leading to a large capacitance; the nickel surface layer is of a high work function, resulting in a thermally sensitive electrode potential. Such a system is ideal for thermally chargeable supercapacitor (TCS) system, which converts low-grade heat (LGH) to ...

Nanoporous carbon based thermally chargeable supercapacitors (TCS) are characterized in a set of experiments for low-grade heat harvesting and storage. A TCS consists of two nanoporous electrodes immersed in an electrolyte solution. When the temperature of one of the electrodes rises, its electrode potential increases, and a significant amount of thermal energy is converted to electric energy. ...
