The chair conformation of C-methylcalix[4]resorcinarene in a novel, stepped, supramolecular framework

The previously unobserved chair conformation of C-methylcalix[4]resorcinarene has been found in three different supramolecular solids, prepared by hydrothermal synthesis. The existence of the chair, crown and flattened cone conformations of C-methylcalix[4]resorcinarene demonstrates the dependence of the molecular conformation upon the templating molecules, and upon the specifics of the crystal...

Carbon nanofiber supercapacitors with large areal capacitances

We develop supercapacitor SC devices with large per-area capacitances by utilizing three-dimensional 3D porous substrates. Carbon nanofibers CNFs functioning as active SC electrodes are grown on 3D nickel foam. The 3D porous substrates facilitate a mass loading of active electrodes and per-area capacitance as large as 60 mg /cm2 and 1.2 F /cm2, respectively. We optimize SC performance by develo...
