We report a method for fabrication of free-standing porous gold material with high surface area, and well-defined, tunable pore morphology. Porous gold is formed via a simple procedure which involves an acidic treatment of a commercially available co

The magical powers of enzymes have been attributed to their ability to bind specific substrates and catalyze reactions of the bound substrate. Artificial enzymes synthetically mimic the binding and the catalytic site to produce molecules that are not

Monomodifications of cyclodextrins to give selectively 2-, 3-, or 6-substituted product is a challenging task because of the number of hydroxyl groups that can potentially react with the incoming reagent. The principles and the methods involved in ma

One of the problems in cyclodextrin chemistry is the unequivocal determination of structures of systems under investigation. A simple procedure that can be used for the determination of the position of the substitution in these systems is presented h
