Compatibility between TRIZ contradiction matrix and LT-units system / Kompatibilnost između TRIZ matrice kontradiktornosti i LT-sistema
(University of Belgrade - Faculty of Mechanical Engineering, Belgrade, 2020)
The contradiction matrix is the most popular tool of the Theory of Inventive Problem Solving (TIPS, rus. TRIZ). It consists of 39 engineering parameters and 40 principles. Intersecting a parameter that is improving with ...
Validation of a novel perfusion bioreactor system in cancer research
(Savez hemijskih inženjera, Beograd, 2020)
Development of drugs is a complex, time- and cost-consuming process due to the lack of standardized and reliable characterization techniques and models. Traditionally, drug screening is based on in vitro analysis using ...
Metal-loaded zeolite remediation of soils contaminated with pandrug-resistant Acinetobacter baumannii
(Inst Medical Research & Occupational Health, Zagreb, 2020)
Due to the development of resistance to antimicrobial agents, bacterium Acinetobacter baumannii is nowadays a leading cause of nosocomial outbreaks. Clinically relevant A. baumannii outside hospital settings including ...
Production of sub-micro sized silver particles by chemical reduction method in an environmentally-friendly manner
(Savez inženjera metalurgije Srbije, Beograd, 2020)
Silver nitrate in the solution was reduced in the presence of the dispersants by ascorbic acid, and silver particles were generated. The main goal was to examine the influence of different dispersants. The purpose was to ...
Micromechanical analysis of fatigue and crack growth in carbon-fiber epoxy composites based on mechanical testing
(Savez hemijskih inženjera, Beograd, 2020)
The paper presents static and dynamic tests of carbon/epoxy composite materials with fiber orientation at 0 degrees/90 degrees and +/- 45 degrees. The main tensile properties were determined as a basis for subsequent dynamic ...
DEALLOYING OF PdNi5 ALLOY IN 0.5M SULFURIC ACID / DEALLOYING PdNi5 LEGURE U 0.5M SULFATNOJ KISELINI
(Beograd : Union of Mechanical and Electrotechnical Engineers and Technicians of Serbia (SMEITS), Society for Renewable Electrical Power Sources, 2023)
Palladium alloys with low nickel content are commonly used as catalyst-trap for platinum or
platinum-rhodium catalysts in the process of production of nitric acid. Pure palladium and,
consequently, alloys with a high ...
PHYSICO-CHEMICAL CHARACTERIZATION OF PCBs / FIZIČKO-HEMIJSKA KARAKTERIZACIJA ŠTAMPANIH PLOČA
(Beograd : Union of Mechanical and Electrotechnical Engineers and Technicians of Serbia (SMEITS), Society for Renewable Electrical Power Sources, 2023)
Recycling of printed circuit boards (PCBs) is an extremely complex and sensitive process. Physicochemical
characterization of printed circuit boards is significant for choosing the optimal
processing procedure. The aim ...
