Possible improvement of methanol synthesis exploiting forced periodic operation: Analysis using the Nonlinear Frequency Responce Method
(The Wilhelm und Else Heraeus-Stiftung, Germany, 2022)
Forced periodic operations, as one way of Process Intensification, can be used in order to achieve better performances of chemical reactors, in comparison to conventional steady-state operation. In this study the Nonlinear ...
Challenges and doubts of electrochemical energy conversion and storage / Izazovi i dileme elektrohemijske konverzije i skladištenja energije
(Beograd : Savez hemijskih inženjera Srbije / Belgrade : Association of the Chemical Engineers of Serbia, 2022)
Apstrakt Civilizacija se od kraja 20. veka suočava sa mnogim izazovima, od koji su neki od njih toliko ozbiljni da ugrožavaju i sam opstanak čovečanstva. Za neke se može reći da su novi, kao što je globalno zagrevanje, ali ...
Lignicolous mushroom Fomitopsis pinicola as a potent inhibitor of lipid peroxidation
(Novi sad: Matica Srpska, 2022)
Excessive production of reactive oxygen species (ROS) often results in irreversible cell damage and leads to a number of disorders such as hypertension, heart disease, diabetes, inflammation, premature aging and cancer. ...

Transesterification of used cooking sunflower oil catalyzed by hazelnut shell ash
(Elsevier, 2022)
Hazelnut shell ash was investigated as a new base catalyst for the transesterification of used cooking sunflower oil to biodiesel. To understand its catalytic properties, the prepared ash was characterized by EDX, XRD, ...
TiO2–CeO2 composite coatings for photocatalytic degradation of chloropesticide and organic dye
(Switzerland: Springer Nature, 2022)
Spray pyrolysis was used to deposit CeO2–TiO2 coatings on stainless steel substrates. The addition of CeO2 to TiO2 changes morphology of the coatings, causing the surface to become laced and some CeO2 ions are incorporated ...
