Eco-friendly technology for gel-coat and fireproofing material production using bio-renewable and waste materials
(ООО «Центр «АЮМЭЛЬ», 2020)
Innovative technology has been developed for the production of gelcoat and materials of reduced flammability based on unsaturated polyester resins. These materials were synthesized from raw materials obtained from waste ...
Optimization of heterogeneously catalyzed methanolysis in microreactor using a green eggshell catalyst
(Cluster of Excellence The Fuel Science Center, 2020)
Calcium oxide was derived from chicken eggshell (ES) by calcination at 900 °C. To improve catalyst performance, the catalyst was treated by the hydration-dehydration method. The new catalyst, with improved structural and ...
Influence of cultivar, soil conditioners and NPK fertilizers on yield components and bean grain yield
(Banja Luka : University of Banja Luka, Faculty of Agriculture, 2021)
The primary goal of bean production is to obtain high and stable yields, in which an
important role. For that reason, in this manuscript we investigated the impact of
cultivar, soil conditioners and NPK fertilizer on ...
Predikcija brzine na 3D štampaču primenom veštačkih neuronskih mreža
(Uniiverzitet u Beogradu - Mašinski fakultet, 2020)
U ovom radu, izvršena je analiza i predikcija brzina štampe u eksploatacionim uslovima. Postoje
odstupanja zadane brzine na štampaču od proračunate stvarne vrednosti. S tim u vezi, postoji i razlika u
vremenima izrade. ...
Impact of relaxation time of activated mixture on ceramics synthesis for electronics purposes / Uticaj vremena relaksacije aktivirane smeše na sintezu keramike za namenu u elektronici
(Beograd : Savez mašinskih i elektrotehničkih inženjera i tehničara Srbije - SMEITS, 2020)
Due to its properties, cordierite, 2MgO·2Al2O3·5SiO2, is nowadays an attractive ceramic material
for various applications but with very high sintering temperature. Mechanochemical activation
of the initial components ...
Removal of arsenic(III) oxyanions from wastewater using aminosilane -modified natural and synthetic zeolite
(Croatia : Croatian Zeolites Association, 2021)
Silanization of the natural and synthetic zeolites as well as their use as adsorbents for removing arsenic(III) oxyanions from wastewater are the topic of this paper. Two types of zeolite were used: natural zeolite-clinoptilolite ...
Laser techniques and couplings with other techniques in contemporary problem solving in theory and practice
(Academy of Sciences and Arts of the Republic of Srpska / Академија наука и умјетности Републике Српске, 2020)
Problems of today, pro et contra of new breakthroughs in high frequencies and pandemics, seem to have called for even more complex correlations and couplings of the fields: science, empiria (practice), mass-media in mastering ...
Fractal reconstruction of fiber-reinforced polymer composites
(Belgrade : Serbian Chemical Society, 2021)
Polymers offer the possibility of different reinforcement incorporation due to a broad range of
chemical structures.Along with this feature, their light weight and processing ease made them
a class of materials that have ...
