LT - Contradiction Matrix
(Fme Transactions, 2021)
Altschuller's Contradiction Matrix and Bartini-Kuznetsov's LT - Table represent two different tools for solving inventive problems based on the same dialectical principle. It starts from the premise that there are ...
Defining the ideality of the protective masks by the mathematical modeling method / Određivanje idealnosti zaštitnih maski metodom matematičkog modelovanja
(University of Belgrade - Faculty of Mechanical Engineering, Belgrade, 2019)
Technical contradiction occurs when the system improves one parameter, which automatically causes the deterioration of some of its other parameters. In such a situation, instead of usual acceptance of the optimization of ...
Properties of cotton yarns after oxidation of potassium permanganate in an acidic environment / Svojstva pamučne pređe posle oksidacije kalijum-permanganatom u kiseloj sredini
(Engineering Society for Corrosion, Belgrade, Serbia, 2017)
The impact of nonselective cellulose oxidation (cotton fibre) by potassium permanganate in acidic environment, with or without additional treatment by sodium metabisulfite, on change of sorption (silver ions sorption), and ...
The influence of novel organic gold complex on photoresist layers of printed circuit boards
(Savez inženjera metalurgije Srbije, Beograd, 2015)
The goal of this paper was to study the influence of organic gold complex based on mercaptotriazole on photoresist layers used in manufacturing of printed circuit boards (PCBs). Investigations were performed by immersion ...
Production of rubber plasticizers based on waste PET: Techno-economical aspect / Sinteza plastifikatora iz otpadnog PET-a za primenu u gumenim proizvodima - tehno-ekonomska analiza
(Engineering Society for Corrosion, Belgrade, Serbia, 2017)
Production of rubber plasticizers, based on waste poly(ethylene terephthalate) (PET), and economic effectiveness of developed technologies are presented and discussed. Waste PET glycolyzates, named diisononyl terephthalate(DINTP), ...
Ni-pd/al(2)o(3) catalyst supported on reticulated ceramic foam for dry methane reforming
(Savez inženjera metalurgije Srbije, Beograd, 2015)
In the present study, Ni-Pd/Al2O3 catalyst supported on alpha-Al2O3 based foam was prepared and evaluated in the dry methane reforming process. Corresponding metal chlorides were deposited to the foam surface by impregnation ...
Alkyd nanocomposite coatings based on waste pet glicolyzates and modified silica nanoparticles / Alkid nanokompozitni premazi bazirani na otpadnim pet glikolizatima modifikovani nanočesticama silike
(Engineering Society for Corrosion, Belgrade, Serbia, 2016)
Synthesis of high-performance alkyd resins (ARs) based on waste poly(ethylene terephthalate) (PET) glycolyzates is presented. PET glycolyzates were synthesized by catalytic depolymerization with trimethylolpropane (TMP) ...
