Вредновање геоеколошких детерминанти Бачке у функцији одрживог развоја
(Природно-математички факултет, Нови Сад, 2022-04-19)
Докторска дисертација је настала из потребе синтезе физичкогеографских схватања о Бачкој, пошто се озбиљнији научни приступ у проучавању природних ресурса Бачке односи на истраживања још од седамдесетих година прошлог века. ...
Assessment of observed and projected climate changes in Bačka (Serbia) using trend analysis and climate modeling
(Hungarian Meteorological Service, 2022-03-08)
Climate change is one of the largest environmental issues causing hydroclimatological extremes such as floods, droughts, and aridity. The aim of this study is to assess the observed and projected climate changes in Bačka ...
KORELACIJA IZMEĐU NAČINA AKTIVIRANJA MONTMORILONITA K10 I SADRŽAJA FORMALDEHIDA U UREA-FORMALDEHIDNIM KOMPOZITIMA
(Faculty of Management Herceg Novi, 2022-05-26)
U ovom radu je izvršeno poređenje načina aktiviranja montmorilonita (MMT) K10 sa sadržajem formaldehida (FA) u urea-formaldehidnim (UF) kompozitima. Uzorci MMT-a K10 su aktivirani na dva načina: termički i pomoću sumporne ...
Correlation between methods of activation of montmorilonite K10 and formaldehyde content in urea-formaldehyde composites
(Faculty of Management Herceg Novi, 2022-05-26)
In this paper, the methods of activation of montmorillonite (MMT) K10 with the content of formaldehyde (FA) in urea-formaldehyde (UF) composites are compared. MMT K10 samples were activated in two ways: thermally(physical ...
Cross-linked bio/inorganically modified urea-formaldehyde resins: influence of γ-radiation on formaldehyde content
(2022-06-13)
The effect of γ–irradiation on hydrolytic stability of nano-silica, nano-titania, and wood flour (WF) modified urea-formaldehyde (UF) resins was investigated. Modified UF resin with wood flour (Pinus silvestris L.) as ...

Polymers are the subject of intensive research and development, not only in science but also in industry. In the last few years, many studies have been conducted on conjugated polymers, and this study of polymers has ...
A Sensitive Voltammetric Sensor for Caffeic Acid Made from Thermolised Modified UF Resins With Incorporated Fe(III) and Ti(IV) Oxide Particles
(University of Novi Sad, Faculty of Technology Novi Sad, 2022-10-20)
Domestic high performance electrode material was prepared by thermolysis of in situ synthesized urea-formaldehyde (UF) resins modified with Fe(III) nitrate and Ti(IV) oxide in different combinations: iron salt and UF resins ...
INFLUENCE OF MODIFIED MONTMORILLONITES ON FORMALDEHYDE CONTENT IN UREA-FORMALDEHYDE/MONTMORILLONITE COMPOSITES
(University of Novi Sad, Faculty of Technology Novi Sad, 2022-10-20)
The effect of different montmorillonites (KSF and K10) and their modifications (Na-KSF, Na-K10) on content of formaldehyde-FA (free and liberated) modified urea-formaldehyde (UF) composites was investigated. KSF and K10 ...
An Improved Modification of Accelerated Double Direction and Double Step-Size Optimization Schemes
(MDPI, 2022-01-13)
We propose an improved variant of the accelerated gradient optimization models for solving unconstrained minimization problems. Merging the positive features of either double direction, as well as double step size accelerated ...
