Polyols and Organic Acids Adsorption Onto Activated Carbon, and Its Role in Aqueous- Phase Catalytic Hydrogenation Rates

Increasing global energy demands have driven research in both alternative renewable energy supplies and synthesis of commodity chemicals from bio-based feedstocks. Many prior studies have used noble metal supported on activated carbon as catalysts for hydrogenation reactions that are often required for such commodity chemical production and often take place in aqueous solution. To gain a deeper...

An alternative to hydrogenation processes. Electrocatalytic hydrogenation of benzophenone

The electrocatalytic hydrogenation of benzophenone was performed at room temperature and atmospheric pressure using a polymer electrolyte membrane electrochemical reactor (PEMER). Palladium (Pd) nanoparticles were synthesised and supported on a carbonaceous matrix (Pd/C) with a 28 wt % of Pd with respect to carbon material. Pd/C was characterised by transmission electron microscopy (TEM), and t...

Future of microbial polyesters

Numerous microorganisms accumulate polyesters classified as polyhydroxyalkanoates (PHAs) as carbon and energy storage material when the growth condition is unfavorable in the presence of excess carbon source. Natural PHAs typically consist of various (R)-hydroxycarboxylic acids, and exhibit different material properties depending on the monomer composition. Such diversity comes from different m...

Biomedical Applications of Biodegradable Polyesters

The focus in the field of biomedical engineering has shifted in recent years to biodegradable polymers and, in particular, polyesters. Dozens of polyester-based medical devices are commercially available, and every year more are introduced to the market. The mechanical performance and wide range of biodegradation properties of this class of polymers allow for high degrees of selectivity for tar...
