General description
Citric acid is a natural component widely usedin many industrial applications such as chelation, buffering, pH adjustment,and derivatization. It can also be used as a reagent in condensation, acidcatalysis, cycloaddition, deprotection, and decarboxylation reactions.
Application
Citric acid can be used as a reactant to synthesize:
- Trialkyl citrates via sulfuric acid-catalyzed esterification with aliphatic alcohols C2-C5.
- Biodegradable thermoset polymer via catalyst-free polycondensation reaction.

Capsule endoscopy is an attractive alternative to colorectal cancer screening by conventional colonoscopy, but is currently limited by compromised mucosal visibility because of the lack of safe, controlled colonic insufflation. We have therefore developed a novel system of untethered, wireless-controlled
