Optical properties CaWO4:Nd3+/PMMA composite layered structures
(Elsevier, Amsterdam, 2019)
In this article, we report characterization of the layered composite fabricated from Nd3+ doped calcium twigstate single crystal (CaWO4 :Nd3+) and poly(methyl methacrylate) - PMMA with various organic-inorganic interfaces: ...
The enhanced removal of cationic dyes in binary system using novel copolymers with two kinds of acidic groups
(Elsevier Science Bv, Amsterdam, 2015)
In this study novel copolymer hydrogels based on methacrylic acid (MAA) and 2-acrylamido-2-methylpropane sulfonic acid (AMPS) were synthesized by free-radical aqueous copolymerization and characterized. Derived P(MAA-co-AMPS) ...
Challenging the difference between white and brown Agaricus bisporus mushrooms: Science behind consumers choice
(Emerald Group Publishing Ltd, Bingley, 2018)
Purpose The purpose of this paper is to examine compositional differences between brown and white varieties of Agaricus bisporus during shelf life and to determine if the growing demand for the brown variety is scientifically ...
The effect of trace elements on wheat straw degradation by Trametes gibbosa
(Elsevier Sci Ltd, Oxford, 2014)
The aim of the study was comparative analysis of ligninolytic enzyme productions of Trametes gibbosa and its ability to degrade wheat straw, as well as effect of trace elements on those processes. Mn-oxidizing peroxidases ...
Pollen Tube Growth and Embryo Sac Development in 'Pozna Plava' Plum Cultivar Related to Fruit Set
(Springer, New York, 2019)
A newly released, late ripening plum cultivar 'Pozna Plava' sets fruit poorly, although it produces high quality fruit. This study aimed to evaluate which factors in the reproductive process could be related to the lack ...
Structural and biological evaluation of lignin addition to simple and silver-doped hydroxyapatite thin films synthesized by matrix-assisted pulsed laser evaporation
(Springer, Dordrecht, 2015)
We report on thin film deposition by matrix-assisted pulsed laser evaporation of simple hydroxyapatite (HA) or silver (Ag) doped HA combined with the natural biopolymer organosolv lignin (Lig) (Ag:HA-Lig). Solid cryogenic ...
Towards antimicrobial yet bioactive Cu-alginate hydrogels
(IOP Publishing Ltd, Bristol, 2016)
The simplest approach to enhance alginate hydrogel characteristics and functional properties is to replace the calcium in the process of alginate gelation with other metallic ions which are essential for living systems. ...
A novel chitosan gels: Supercritical CO2 drying and impregnation with thymol
(Wiley, Hoboken, 2018)
Supercritical carbon dioxide (scCO(2)) technology was used for preparation of functional pH sensitive chitosan-based aerogels characterized with micron size pores and their impregnation with thymol as a natural bioactive ...
Silicon nanostructuring by Ag ions implantation through nanosphere lithography mask
(Elsevier Science Bv, Amsterdam, 2019)
Nanosphere lithography is an effective technique for high throughput fabrication of well-ordered patterns on large areas. This study reports on nanostructuring of silicon samples by means of Ag ions implantation through ...
Testing of the efficiency of military devices for personal respiratory protection in relation to sub-micron particles of biological agents
(Inst Materials Physics, Bucharest, 2012)
The construction of biological weapons and tactics of its application dictate that dissemination of biological agents on the target has to be in the form of aerosols. The work was done on the effectiveness of filtration ...
