Energy Efficient Poly(Lactide) Obtaining by Microwave Synthesis
(University of Maribor Press, 2017)
The world is faced with the consequences of drastic reduction in fossil fuel reserves, because of their widespread use, not only as an energy source, but also as a feedstock for monomers obtaining. In order to solve this ...
Preparation of ZrO2 and Al2O3 thin-films on stainless steel by spray pyrolysis
(Research Trends in Contemporary Materials Science, 2007)
We have investigated the deposition of ZrO2 and Al2O3 films on a stainless steel (SS) substrate by spray pyrolysis method. The ZrO2 films were deposited from aqueous solution of zirconium dinitrate oxide. For Al2O3 films, ...
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 ...
Predikcija brzine vetra na teritoriji Libije primenom veštačkih neuronskih mreža
(Univerzitet u Beogradu - Mašinski fakultet, 2018)
Libija je zemlja bogata naftom i prirodnim gasom čije učešće u proizvodnji električne energije je preko 90%.
Međutim, sve više su u upotrebi i obnovljivi izvori energije, kao što je energija vetra. U Libiji postoji ...
Adsorption-desorption phase noise in RF MEMS/NEMS resonators
(10th International Conference on Telecommunications in Modern Satellite, Cable and Broadcasting, 2011)
In this paper the analysis is presented of the dependence of adsorption-desorption phase noise in MEMS/NEMS resonators of their resonant frequency, operating pressure and temperature. Results of the analysis are useful for ...
Cirkularna ekonomija: primena zelene hemije u privrednom sektoru

(Београд : Централни институт за конзервацију и Друштво за етичност и вредновање у култури и науци, 2020)
Традиција употребе последњег средства (Ultima ratione) у околностима крајњег случаја (In extremis) у заштити културног наслеђа, у Србији је кроз историју осведочена у очувању значајног материјалног и духовног наслеђа. У ...
Superkritična ekstrakcija kao metoda za uklanjanje pesticida iz zemljišta
(Univerzitet u Kragujevcu, Agronomski fakultet u Čačku, 2016)
Cilj ovog rada je ukazivanje na mogućnost primene superkritične ekstrakcije sa ugljendioksidom na dekontaminaciju zemljišta zagađenih pesticidima (u ovom slučaju atrazinom). Analizirani rezultati ukazuju da se ova metoda ...
Customization of evanescent near fields on freestanding plasmonic nanomembranes
(Belgrade: ETRAN – Society for electronics, telecommunication, computing, automatics and nuclear engineering, 2018)
For a very long time optical evanescent near fields have been considered useless for practical applications and remained a theoretical curiosity. However, with advances in micro and nanotechnologies and the decreasing sizes ...
