Internal redundancy - the way to improve robot dynamics and control performances
(Dordrecht : Kluwer Academic Publishers, 2000)
The research follows the concept of variable geometry. The concept was originally introduced for general mechanical system in order to improve its dynamic behaviour. Here, we apply the concept to robots. It can be shown ...
Investigation of sintering kinetics of NiO using photo acoustic spectroscopy
(Belgrade : International Institute for the Science of Sintering, 2004)
Sintering kinetics of NiO was investigated using photo acoustic spectroscopy This method was used to follow the change of phase and amplitude of the photo acoustic signal of nickel-oxide samples sintered at 1373 K for ...
Oxidation of metallic binder powder and its influence on mechanical properties metal-diamond composite
(Sendai : Japan Institute of Metals, 2000)
In this paper, the properties of metallic binders based on Co, Fe, bronze and their influence on mechanical characteristics of metallic binder-diamond composites, obtained by hot pressing of these powders, were analyzed. ...
Surface reconstruction during the adsorption/desorption of OH species onto Cu(111) and Cu(100) in O. 1 M NaOH solution
(Belgrade : Serbian Chemical Society, 2002)
The process of adsorption/desorption of OH- species onto Cu(111) and Cu(100) in 0.1M NaOH solution has been investigated by cyclic voltammetry and the potentiostatic pulse technique. Investigation of the electrochemical ...
Gadolinium-labelled cell scaffolds to follow-up cell transplantation by magnetic resonance imaging
(Basel : MDPI, 2019)
Cell scaffolds are often used in cell transplantation as they provide a solid structural support to implanted cells and can be bioengineered to mimic the native extracellular matrix. Gadolinium fluoride nanoparticles ...
Electronic structure and X-ray spectroscopic properties of the HfFe2Si2 compound
(West Ukrainian Physical Society, 2019)
The valence band electronic structure of HfFe2Si2 has been established for the first time based on X-ray emission spectroscopy measurements. The band structure and X-ray emission spectra have been also obtained theoretically ...
Electrochemically deposited Ni+WC composite coatings obtained under constant and pulsating current regimes
(Netherlands : Kluwer Academic Publishers, 2004)
A series of Ni+WC composite coatings were obtained by electrodeposition on a rotating disc electrode (RDE)from a commercially available Watts bath containing additives for brightness and smoothing and insoluble WCparticles, ...
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 ...
Exopolysaccharide Produced by Probiotic Strain Lactobacillus paraplantarum BGCG11 Reduces Inflammatory Hyperalgesia in Rats
(Lausanne : Frontiers, 2018)
The aim of this study was to test the potential of high molecular weight exopolysaccharide (EPS) produced by the putative probiotic strain Lactobacillus paraplantarum BGCG11 (EPS CG11) to alleviate inflammatory pain in ...
Poly(lactide-co-glycolide)/silver nanoparticles: Synthesis, characterization, antimicrobial activity, cytotoxicity assessment and ROS-inducing potential
(Elsevier, 2012)
Silver nanoparticles (AgNps) were prepared by modified chemical reduction with poly (α, γ, l-glutamic acid) (PGA) as capping agent. These Ag/PGA nanoparticles (AgNpPGAs) were highly stable over long periods of time without ...
