Poly(D,L-lactide-co-glycolide)/hydroxyapatite core-shell nanospheres. Part 1: A multifunctional system for controlled drug delivery
(Colloids and Surfaces B: Biointerfaces, 2011)
Biodegradable poly(D,L-lactide-co-glycolide) (PLGA) and bioactive hydroxyapatite (HAP) are selected for the formation of a multifunctional system with the specific core-shell structure to be applied as a carrier of a drug. ...
Multifunctional PLGA particles containing poly(l-glutamic acid)-capped silver nanoparticles and ascorbic acid with simultaneous antioxidative and prolonged antimicrobial activity
(Elsevier, 2014)
A water-soluble antioxidant (ascorbic acid, vitamin C) was encapsulated together with poly(l-glutamic acid)-capped silver nanoparticles (AgNpPGA) within a poly(lactide-co-glycolide) (PLGA) polymeric matrix and their ...
Adsorption-desorption noise in microfluidic biosensors operating in multianalyte environments
(Elsevier, 2015)
We present a theoretical model of adsorption-desorption (AD) noise in microfluidic biosensors operating in multianalyte environments. This noise is caused by the stochastic nature of the processes that generate the sensor ...
Synthesis and Characterization of Multifferoics 16%(Fe2O3)4%(BaCO3)80%(BaTiO3)
(Belgrade : Serbian Ceramic Society, 2017)
The initial powder (16 % Fe2O3, 4 % BaCO3, 80 % BaTiO3) was mechanically activated in a planetary mill for 20, 80, 120, 160, 200 and 220 minutes in air. Modified Faraday method was used to perform magnetization measurements ...
Fluctuations of the number of adsorbed molecules due to adsorption–desorption processes coupled with mass transfer and surface diffusion in bio/chemical MEMS sensors
(Elsevier, 2014)
In this study we have developed, for the first time, the comprehensive theoretical model of the fluctuations of the number of adsorbed molecules in MEMS chemical and biological sensors, taking into account the processes ...
Sintering effects on microstructure and dielectric properties of CCTO ceramics
(Belgrade : Materials Research Society of Serbia, 2012)
A perovskite-type compound, calcium copper titanate (CaCu3Ti4O12, CCTO) attracted ever increasing attention for its practical applications in microelectronics, especially for preparation of capacitors and memory devices. ...
Humanoid robot Marko - an assistant in therapy for children
(Belgrade : Institute for Research and Design in Commerce and Industry, 2014)
This paper reports on work in progress towards development of a robot to be used as assistive technology in treatment of children with developmental disorders (cerebral palsy). This work integrates two activities. The first ...
The Ho2O3 Concentration Influence on BaTiO3 – ceramics Fractal Structures
(Belgrade : Serbian Ceramic Society, 2014)
An influence of dopant concentration on microstructure and dielectric properties of doped BaTiO3-ceramics is developed based on fractal geometry. Using different technological parameters and different additives the structure ...
Automatic devices for electrochemical water treatment with cooling of electrolyte
(Association of the Chemical Engineers of Serbia, 2016)
The most common disinfectants for water treatment are based on chlorine and its compounds. Practically, water treatments with chlorine compounds have no alternative, since they provide, in comparison to other effective ...
Structural Changes, Dielectric and Ferroelectric Properties of Tribophysically Activated BaTiO3
(Belgrade : Serbian Ceramic Society, 2012)
In order to obtain nanocrystalline material which can be used in MLCC production, the investigations of the influence of BaTiO3 powder tribophysical activation (TPA) on its structural changes, dielectric and ferroelectric ...
