Nanofeatures of resorcinol–formaldehyde carbon microspheres
Abstract Resorcinol–formaldehyde activated carbon xerogels were synthesized at certain conditions, and their morphology was studied experimentally to examine their detailed nature on the nanoscale level, which has not been reported before. Traditionally, such materials are reported to consist of microspherical particles of carbon.

Resorcinol-Formaldehyde and Carbon Aerogel Microspheres [PDF]
AbstractAerogels are a unique class of materials possessing an open-cell structure with ultrafine cells/pores (<100nm), high surface area (400–1100 m2/g), and a solid matrix composed of interconnected particles, fibers, or platelets with characteristic dimensions of 10nm.
