Microstructure and thermal properties of Bi-Sn eutectic alloy
(München : Carl Hanser Verlag, 2020)
Alloys based on Sn and Bi are considered to be one of the best soft lead-free solders due to their low melting temperature and low price. In addition, Bi-Sn alloy with a eutectic composition represents a promising candidate ...
Synthetic route towards 1,2,3,4-tetrahydroquinoxaline/piperidine combined tricyclic ring system / Синтетски пут за добијање 1,2,3,4-тетрахидрохиноксалинскo/пиперидинског трицикличног система
(Serbian Chemical Society, 2022)
The synthetic route toward novel tricyclic, nitrogen-containing system is disclosed. Three novel compounds possessing structural features of 1,2,3,4-tetrahydroquinoxaline and decahydropyrido[3,4-b]pyrazine are synthesized ...
The Balkan Macrophyte Index (BMI) for Assessment of Eutrophication in Lakes
(Sofia, Bulgaria : Prof. Marin Drinov Academic Publishing House, 2020)
Aquatic plants have long been used as indicators for nutrient enrichment in lakes. In the Mediterranean, however, the process of developing and intercalibrating macrophyte assessment methods for lakes has lagged behind ...
Extraction kinetic of some phenolic compounds during Cabernet Sauvignon alcoholic fermentation and antioxidant properties of derived wines / Екстракциона кинетика на некои фенолни соединенија во текот на алкохолната ферментација на грозје од сортата каберне совињон и антиоксидантни својства на добиените вина
(The Society of Chemists and Techonogists of Macedonia, 2020)
In this study, we estimated the usage of Cabernet Sauvignon in microvinifications, obtaining wines with increased phenolic compound content. Kinetic extraction of phenolic compounds during alcoholic fermentation was affected ...
