An Experimental Study of Mechanical Properties and Heat Transfer of Acrylic Composites with Structural and Surface Modified Al2O3 Particles
(International Institute for the Science of Sintering (IISS), 2020)
Thermal properties of acrylate-based composite combined with alumina-based particles were investigated. The composites were made of poly (methyl methacrylate) (PMMA) modified with dimethyl itaconate (DMI) as a matrix. Neat ...
Thermodynamic and transport properties of biomass-derived furfural, furfuryl alcohol and their mixtures
(MDPI, 2021)
The limited reserves and well-known disadvantages of using fossil energy sources have increased the need for appropriate renewable substitutes in the production of various chemicals and materials. Biomass has been shown ...
SnO2-Containing Clinoptilolite as a Composite Photocatalyst for Dyes Removal from Wastewater under Solar Light
(MDPI, Basel, 2020)
Due to their adsorbent, ion exchange and catalytic properties zeolites are suitable for a variety of applications. We report on the photocatalytic activity of a readily available and inexpensive natural zeolite clinoptilolite ...
Enhanced Interface Adhesion by Novel Eco-Epoxy Adhesives Based on the Modified Tannic Acid on Al and CFRP Adherends
(MDPI, Basel, 2020)
This paper presents a new process for obtaining eco-epoxide adhesives synthesized from bio-renewable raw material (tannic acid-TA) and used for bonding lightweight materials (aluminum (Al) and carbon fiber reinforced polymer ...
A survey on the characterization and biological activity of isatin derivatives
(Srpsko hemijsko društvo, Beograd, 2020)
The derivatives of isatin have already been known to display a variety of biological activities. Therefore, the studies on their activity and its relation to structure have recently become a popular subject for investigation. ...
Enhanced adhesion of acrylic adhesives with dental tissue with the addition of aluminum oxide based particles / Poboljšana adhezija akrilnih adheziva sa zubnim tkivom uz dodatak čestica na bazi aluminijum oksida
(Savez inženjera i tehničara Srbije, Beograd, 2020)
Composite materials based on acrylate UV-cured polymers (Bis-GMA/TEGDMA) as a matrix and reinforcements that can be selected in order to adjust the properties of the obtained composite are used in the field of dental ...
Mathematical - Physical Model of Solving Inventive Problems
(Fme Transactions, 2021)
The spatial-temporal LT- contradiction matrix is an inventology tool that enables exact calculations of certain parameters in an engineering system through mathematical-physical modeling. It objectifies the decision-making ...
Dual responsive hybrid hydrogels for controlled release of local anesthetic
(Savez mašinskih i elektrotehničkih inženjera i tehničara Srbije (SMEITS), 2021)
Intelligent hydrogels, such as pH sensitive hydrogels based on
poly(methacrylic acid) (PMAA) are widely used for targeted drug
delivery. Still, PMAA lack of good mechanical properties often
limits its application. ...
Ecological Risk Assessment of Heavy Metals in the Soil at a Former Painting Industry Facility
(Frontiers Media Sa, Lausanne, 2020)
Soil samples from the site of the former largest paint and varnish factory in ex-Yugoslavia were analyzed for arsenic and eight heavy metals (Pb, Cd, Zn, Cr, Ni, Cu, Fe, and Hg). Several additional soil properties (pH, ...
Poly(vinyl alcohol)/chitosan hydrogels with electrochemically synthesized silver nanoparticles for wound dressing applications
(Int Assoc Physical Chemists-Iapc, Zagreb, 2020)
Polymer-based hydrogel materials are excellent candidates for new-generation wound dressings with improved properties, such as high sorption ability, good mechanical properties and low adhesiveness. Cross-linked hydrogel ...
