Carbon precursors with structural and compositional information in their molecular backbone, pre-formed covalent bonds, or integrated functional groups enable the design of carbon materials that can be tailored for certain applications. We review this exciting field of synthetic approaches based on ...
Carbon molecular sieves have some advantages over molecular sieve zeolites in terms of shape selectivity for planar molecules, high hydrophobicity, high resistance to both alkaline and acid media and thermal stability under inert atmosphere at higher temperatures. CMS materials are commercially prepared by...

corals, anemones and jellyfish share a common mechanism to regulate their association with symbiotic algae. Despite evolving independently, these animals all use the same carbon-nitrogen negative feedback loop for algae control, shedding light on the repeated evolution of these marine symbiotic ...
2. After cleaning the sieve tank, start to fill thecarbon molecular sieve. If the air intake pipe enters from the bottom, need to fill 50mm height of activated alumina desiccant first, then start to fill with carbon molecular sieve. If the air intake enters from the upper end, then it'...
CONSTITUTION:Pitch fibers made infusible are preformed into a plate shape and the resulting plate-shaped preform is carbonized at 760-900 deg.C in an inert gaseous atmosphere to produce the objective plate-shaped molecular sieve carbon made of fibrous molecular sieve carbon whose micropore diameter ...
Molecular geometry describes the overall shape of a molecule in terms of how the atoms inside it are arranged. Examples of simple structures are linear molecules like carbon dioxide (0=C=0) and tetrahedral molecules like methane, which consists of a carbon atom with four hydrogen atoms surroundin...

Owed to its excellent visible-light absorption and high activity, g-C3N4 has drawn a lot of attention as a photocatalyst [73,74]. It is entirely composed of carbon and nitrogen and has robust stability (chemical and thermal) owing to the rigid covalent linkage among C and N atoms in its...
