Novel approach to fast determination of cholesterol oxidation products in Cypriot foodstuffs using ultra-performance liquid chromatography-tandem mass spectrometry
Georgiou, Christiana A.; Constantinou, Michalis S.; Andreou, Rafaella; Hapeshi, Evroula; Fatta‐Kassinos, Despo; Kapnissi‐Christodoulou, Constantina P. (2016)This paper reports the development and validation of a new method based on ultra-performance LC coupled to MS/MS for the simultaneous determination of four cholesterol oxidation products (COPs) in foodstuffs in only 4.1 ...

Preparation and characterization of a cerium(IV)-incorporated manganese oxide OMS-2. Effect of cerium(IV) template on octahedral molecular sieves of manganese oxide and characterization of manganese oxide molecular sieves with cerium(IV) as dopant
Hapeshi, Evroula; Theocharis, Charis R. (2008)The manganese oxide material K-OMS-2 was synthesized both via a redox reaction between potassium permanganate and manganese nitrate in an acidic medium (nitric acid) under reflux conditions and by the sol-gel reaction ...

Preparation and characterization of nanoporous solids with composition CexMn1-xO2-y with x values 0 to 1
Hapeshi, Evroula; Theocharis, Charis R. (2006)A series of mixed ceria-mangania solids were synthesised covering the whole concentration range from 0% to 100% cerium. It was shown that at high cerium concentrations a single phase was obtained, whereas at low concentrations ...

Study of the crystallization of nanoporous mixed metal oxide phases
Theocharis, Charis R.; Attipa, Christothea; Hapeshi, Evroula; Tillirou, Aphrodite A.; Kokkinofta, Rebecca I. (2008)A systematic study of the synthesis and characterization of pristine ceria and of mixed cerium/metal oxides has been undertaken. Various synthetic routes were explored, with the crystallization process being examined via ...
