Curcumin nanonization using an alternative small-scale production unit: selection of proper stabilizer applying basic physicochemical consideration and biological activity assessment of nanocrystals
Ines Nikolić, Jelena Antić-Stanković, Dragana Božić, Danijela Ranđelović, Bojan Marković, Dominique Jasmin Lunter, Aleksandar Kremenović, Miroslav Savić, Snežana Savić (2020)As the number of poorly soluble drugs is increasing, nanocrystals have become very interesting due to wide range of application possibilities. Curcumin was used as a model active ingredient in this work. Even though it has many proven positive effects, due to its physicochemical issues, its possibilities have not been fully exploited. The goal of this work was to select optimal conditions for a top-down method for curcumin nanosuspension production, and to perform their comprehensive characterization applying complementary methodologies: ...Ines Nikolić, Jelena Antić-Stanković, Dragana Božić, Danijela Ranđelović, Bojan Marković, Dominique Jasmin Lunter, Aleksandar Kremenović, Miroslav Savić, Snežana Savić.

Regional rockfall exposure assessment, experience from Serbia
Rockfalls are common in hilly and mountainous areas, especially along roads with engineered slopes and cuts. Such is the case for most of the state and local road routes in Central, Serbia, which was the subject in this case study. A road network of 276 km covering roughly 1700 km2 between the cities of Kraljevo, Čačak and Ivanjica is presented. Assessing of such wide areas needs to be conducted from large to site-specific scale, i.e., using GIS spatial tools ...Miloš Marjanović, Biljana Abolmasov, Uroš Đurić, Jelka Krušić, Snežana Bogdanović.

Analysis Of the Process Of Carbon Capture Utilization And Storage In Underground Reservoirs
John Nyame (2024)The importance of mitigating the effects of global climate change has necessitated an in-depth exploration of innovative strategies to reduce carbon dioxide (CO2) emissions. Among these strategies, Carbon Capture, Utilization, and Storage (CCUS) has emerged as a promising and transformative solution. This master thesis delves into the diverse realm of CCUS processes, aiming to unravel the positives challenges, and opportunities within this dynamic field. The analysis begins with a systematic examination of carbon capture technologies, encompassing post-combustion, pre-combustion, and oxy-fuel combustion ......

Identification of the Best Available Renewable Energy Source for Electricity Production in Serbia
Around 2/3 of electricity production in Serbia originates from coal-fired thermal power plants. The most significant domestic coal deposits are lignite deposits, a type of low -quality coal that causes negative health, climate and environmental impacts during the combustion.

Примена CNC машина при обради мермера
Ненад Остојић (2024)Мермер је стена настала метаморфизмом седиментних карбонатних стена, најчешће кречњака или доломита. Мермер се углавном састоји од калцита,кречњака, серпентина и доломита. Његове главне компоненте су углавном калцијум карбонат, који чини више од 50 посто, и други магнезијум карбонат, калцијум оксид, манган оксид и силицијум диоксид, итд. Фазе обраде мермера су: примарно резање мермерних блокова у плоче, површинска обрада мермерних плоча, секундарно резање мермерних плоча, терцијарна обрада (ако је потребно). CNC машина је електро-механички уређај који управља алатима, користећи програмирање путем ...... napaMerapa: Op3uHa Kperatba (m?/h), HIOTpOHIH4a ueJIHuHHX paBHHX TecTepa (kg/m? pe3a), nHoTponikba uezHuHHX aOpa3HBa (kg/m? peya), HIOTPpOIHHIH4 CJIČKTpHuHeC CHeEpTHje CBHX CJIČKTpOMOTOPa IO m? pe3alba , TIOTPpOIIIa BOJIĆ y TOKy pe3atba (I/h), norpotitba Kpeua (kg/m? pe3a), BpeMCHCKO HcKopHinheMe ...
