The influence of reaction time on the properties of microwave synthesized poly(lactide)
(Бања Лука: Академија наука и умјетности РС, 2019)
The consequence of drastic reduction in fossil fuel reserves has forced the
scientific community to find and develop new ways to exploit renewable resources and
optimize the process of polymer materials production. The ...
Forced Periodic Operation: Effect of shapes for two simultaneously imposed modulations
(German reaction Engineering Meeting (DECHEMA), Wuerzburg, Germany, 2019)
The classical design of continuous chemical reactors exploits steady-state operation, which is optimized and maintained by appropriate control systems. Nevertheless, it is well-known that the reactor performance can be ...
Alumina production from purified Bayer liquor / Proizvodnja glinice iz pročišćene Bayerove otopine
(Hrvatska: Hrvatsko društvo kemijskih inženjera i tehnologa
(HDKI), 2019)
Removal of some impurities from Bayer liquor, such as zinc compounds, allows obtaining alumina with low content of impurities incorporated in the crystalline structure. Impurities in alumina influence the quality of products ...
Biodiesel synthesis over green catalyst: The effect of thermal treatment of CaO/Zeolite precursor on catalytic activity
(Belgrade : Serbian Chemical Society, 2019)
The green CaO/Zeolite catalyst for methanolysis of fatty oils was synthesized entirely from the waste materials. CaO derived from chicken eggshell was loaded onto fly ashbased zeolite catalyst carrier by the wet impregnation ...
Evolution of Si Crystallographic Planes-Etching of Square and Circle Patterns in 25 wt % TMAH
(MDPI, 2019)
Squares and circles are basic patterns for most mask designs of silicon microdevices. Evolution of etched Si crystallographic planes defined by square and circle patterns in the masking layer is presented and analyzed in ...
Nickel doped titanate catalysts for photocatalytic hydrogen generation
(Belgrade : Institute of Technical Sciences of SASA, 2019)
This study will focus on investigation of photocatalytic hydrogen production activity over low cost Ni modified titanates, as alternatives for highly cost and low-abundance noble metal based catalysts. The catalysts with ...
Intensification of a chemical reactor for methanol synthesis through forced periodic operations- Evaluation based on Nonlinear Frequency Response Analysis
(2nd International Process Intensification Conference, Leuven, Belgium, 2019)
In this work, the NFR method is implemented for evaluation of possible improvement for the reaction of methanol synthesis by hydrogenation of CO and CO2, using a standard Cu/ZnO/Al2O3 catalyst. For start, a forced periodically ...

(American Chemical Society (ACS), 2019)
Supporting information for X-ray crystallography; Additional experimental details for the synthesis of 1 and 3; Additional computational results for mononuclear structures; Additional computational results for dimer structures.
Organochlorine pesticides in the Tisza River (Serbia): Distribution and risk assessment / Pesticidi u reci Tisi (Srbija) : Distribucija i procena rizika
(Serbia : Matica srpska, 2019)
Paper provided the systematic data on the distribution and risk assess¬ment status of organochlorine pesticides (OCPs) in sediment of the Tisza River (Serbia). The α-HCH, endrin ketone and methoxychlor are the most commonly ...
Modelling and Multi-Criteria Analysis of Anaerobic Digestion Process to Get Upgraded Methane from Bio-Residues in the City of Reykjavik
(MDPI, 2019)
Anaerobic digestion of urban organic wastes, farming slurries or sewage sludge is a
common practice in waste treatment plants. In the city of Reykjavik, the organic waste fraction
constituted by 60% of biomass and 40% ...
