Water, electricity and ion exchange; how Hamish Small sustained the evolution of ion chromatography
Heliyon, 2021 Since the development of synthetic ion exchange resins in 1935, the electrochemical properties of these unique materials have intrigued researchers. In 1951, Hamish Small was introduced to synthetic ion exchange resin when he studied the electromigration

Identification of novel components of Trypanosoma brucei editosomes [PDF]
, 2003 The editosome is a multiprotein complex that catalyzes the insertion and deletion of uridylates that occurs during RNA editing in trypanosomatids. We report the identification of nine novel editosome proteins in Trypanosoma brucei.

Amphiphilic diblock copolymers as functional surfaces for protein chromatography [PDF]
, 2022 Stationary phase plays a crucial role in the operation of a protein chromatography column. Conventional resins composed of acrylic polymers and their derivatives contribute to heterogeneity of the packing of stationary phase inside these columns. Alternative polymer combinations through customized surface functionalization schemes which consist of ...

Removal of disinfection by-product precursors by coagulation and an innovative suspended ion exchange process [PDF]
, 2015 This investigation aimed to compare the disinfection by-product formation potentials (DBPFPs) of three UK surface waters (1 upland reservoir and 2 lowland rivers) with differing characteristics treated by (a) a full scale conventional process and (b ...

Chromatographic separation of mannitol from mixtures of other carbohydrates in aqueous solutions
Czech Journal of Food Sciences, 2021 The isolation of mannitol from natural sources, e.g. from plant extracts or broths, requires considerable time and effort. The separation of mannitol from aqueous solutions containing also glucose, fructose, and sucrose was tested using discontinuous ...
