Adsorption cooling system using carbon aerogel

A method, comprising:

• forming a carbon aerogel on a substrate to produce a highly adsorptive structure, wherein the carbon aerogel is characterized by having a monolithic structure;
• forming a plurality of grooves in one or more surfaces of the substrate, forming a plurality of ridges in one or more of the surfaces of the substrate, forming a plurality of microchannels in one or more of the surfaces of the substrate, and/or forming a plurality of microcapillaries in one or more of the surfaces of the substrate;
• and
• selectively depositing one or more materials onto one or more surfaces of the carbon aerogel using an atomic layer deposition (ALD) technique;
• wherein the carbon aerogel is characterized by having physical characteristics of in-situ formation on the substrate, and
• wherein the carbon aerogel is adhered to peaks and/or valleys of the plurality of grooves and the plurality of ridges.
