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. ...
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, ...
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 ...
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 ...
Hydrogels based on poly(methacrylic acid) and nanocellulose with potential application in dental treatments
(UNIVERSITY OF EAST SARAJEVO FACULTY OF TECHNOLOGY Karakaj 34a, 75 400 Zvornik Republic of Srpska, B&H, 2021)
pH sensitive hydrogels, such as hydrogels based on poly(methacrylic acid) (PMAA), are
tremendous materials with great properties due to which they have application in many fields,

Multipurpose Nonwoven Viscose/Polypropylene Fabrics: Effect of Fabric Characteristics and Humidity Conditions on the Volume Electrical Resistivity and Dielectric Loss Tangent
(Korean Fiber Society, 2020)
In this work, the volume electrical resistivity and dielectric loss tangent of viscose/polypropylene multipurpose nonwoven fabrics were examined. According to the obtained results, the changes in the volume electrical ...
Application of the Integrated Supercritical Fluid Extraction–Impregnation Process (SFE-SSI) for Development of Materials with Antiviral Properties
(MDPI, 2022)
The integrated supercritical fluid extraction–impregnation process (SFE-SSI) was performed to fabricate material with antiviral properties against the herpes simplex virus (HSV). Cotton gauze and starch/chitosan polymer ...
pH-sensitive hydrogels based on poly(methacrylic acid), casein and liposomes for targeted delivery of poorly water-soluble active substances
(Savez mašinskih i elektrotehničkih inženjera i tehničara Srbije (SMEITS), Društvo za procesnu tehniku., 2020)
Polymeric carriers for targeted delivery of poorly water-soluble active substances (PWSAS)
are facing two challenges. First, encapsulation of PWSAS depends on structure of the carrier. Second
limitation is caused by the ...
