The potential of hybrid geopolymer composites
(Belgrade : Institute for Multidisciplinary Research, 2019)
Hybrid geopolymers represent a new class of composite materials formed by incorporating organic polymer into a geopolymer matrix. The properties of hybrid geopolymer depend on the addition of organic phase and the starting ...
Valorization of walnut shell ash as a catalyst for biodiesel production
(Elsevier, 2020)
The catalytic activity of the walnut shell ash was investigated in the biodiesel production by the sunflower oil methanolysis. The catalyst was characterized by the TG-DTA, XRD, Hg porosimetry, N2 physisorption, SEM, and ...
Deep insight into the photoluminescent monocrystalline particles: Heat-treatment, structure, mechanisms and mechanics
(Elsevier, 2019)
The red light emitting down-converting Ag@Y2O3:Eu3+ phosphor particles were synthesized by one-step ultrasonic spray pyrolysis and exposed further to the heat treatment at 1000°C (12h). A detailed investigation on structural ...
BaTiO3-ceramics and grain growth engineering using fractal nature approach
(Societa ceramica italianaPolitecnico di Torino, 2019)
Grain size and morphology of BaTiO3-ceramics are very important characteristics in developing new dielectric devices. Samples with different additives were sintered at different temperatures and times. The microstructure ...
FES Cycling in Persons with Paralyzed Legs: Force Feedback for Setup and Control / info:eu-repo/grantAgreement/MESTD/Integrated and Interdisciplinary Research (IIR or III)/44008/RS//
(Vienna : Medical University of Vienna, 2019)
Cycling assisted by functional electrical stimulation (FES cycling) has many positive effects on the overall health in persons with paralyzed legs due to the injury of the central nervous system (i.e., increases bulk of ...
Supplementary material to Triethanolamine as an efficient cosolvent for biodiesel production by CaO-catalyzed sunflower oil ethanolysis: An optimization study
(Hemijska industrija, 2019)
Figure D1. Normal probability plot of residuals (a), Cook's distances (b) and predicted and actual values of FAEE content (c); Table D1. Results of sequential model sum of squares test; Table D2. Results of lack of fit ...
Примена мултиканалне електромиографије у рехабилитацији
(Универзитет у Београду, Електротехнички факултет, 2020)
Конвенционална површинска електромиографија (сЕМГ) је метод процене мишићне активности. Конвенционални сЕМГ даје локалну слику и јако зависи од положаја електрода у односу на мишић. Да би се добила прецизнија слика мишићне ...
Fractal Nature of Advanced Ni-Based Superalloys Solidified on Board the International Space Station
(Basel : MDPI AG, 2021)
Materials science is highly significant in space program investigation, energy production and others. Therefore, designing, improving and predicting advanced material properties is a crucial necessity. The high temperature ...
Effects of hydrolysis degree and type of protease on antioxidant activity and functionality of egg white protein hydrolysates
(Tatranské Matliare : Slovak Society of Chemical Engineering, 2013)
Enzymatic hydrolysis of egg white proteins has shown great potential to improve their functional properties such as increased solubility, stability, and digestibility, and to reduce protein allergenicity while still retaining ...
Measurement of the human cadaver ossicle vibration amplitude by fiber-optic interferometry
(Rijeka : Croatian Society for Information, Communication and Electronic Technology - MIPRO, 2020)
In this paper we present the results obtained by contactless measurement of vibration of the incus inside the middle ear of a human cadaver, exposed to an external calibrated sound source. The measurement configuration was ...
