Novel Approach for Flavonoid Esters Production: Statistically Optimized Enzymatic Synthesis Using Natural Oils and Application in Cosmetics
(Amer Chemical Soc, Washington, 2019)
The present work describes application of natural triglycerides for lipase-catalyzed esterification of structurally diverse flavonoids-esculin, naringin, and phloridzin. Ester mixtures with laurate, linolenate, or linoleate ...
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 ...
Migration of cypermethrin to and through the PET containers and artificial neural network-based estimation of its emission
(Springer Verlag, 2019)
Nowadays, the extensive use of pesticides in crops production puts a significant challenge to minimize its side effects along with safe production, storage, and after-use treatment. This paper reports results related to ...
Effects of oxidized/treated non-metallic fillers obtained from waste printed circuit boards on mechanical properties and shrinkage of unsaturated polyester-based composites
(Wiley, Hoboken, 2019)
The investigation of the influence of acid/base treatment and addition level of non-metallic fractions (NMFs), obtained by processing of printed circuit boards, on the mechanical properties and shrinkage of unsaturated ...
Arsenic removal by copper-impregnated natural mineral tufa part II: a kinetics and column adsorption study
(Springer Heidelberg, Heidelberg, 2019)
This batch and column kinetics study of arsenic removal utilized copper-impregnated natural mineral tufa (T-Cu(A-C)) under three ranges of particle size. Non-competitive kinetic data fitted by the Weber-Morris model and ...
Influence of 1,2,3,4-butanetetracarboxylic acid concentration on in situ synthesis of cuo/cu2o nanoparticles on cotton and viscose rayon fabrics
(Editura Acad Romane, Bucuresti, 2019)
This study discusses the possibility of in situ synthesis of Cu-based nanoparticles (NPs) on cotton and viscose rayon fabrics previously modified with 1,2,3,4-butanetetracarboxylic acid (BTCA) of different concentrations, ...
Effect of surface activation of alumina particles on the performances of thermosetting-based composite materials
(Sage Publications Ltd, London, 2019)
Two types of alumina particles, commercial (c-Al2O3) and iron doped (Fe-Al2O3), were functionalized with 3-(aminopropyl)trimethoxysilane (one-step) and two-step consecutive process, i.e. firstly using 3-(aminopropyl)trim ...
Dimethyl Itaconate Modified PMMA - Alumina Fillers Composites With Improved Mechanical Properties
(Wiley, Hoboken, 2019)
PMMA poly(methyl methacrylate) has a large spectrum of uses as bone cements, in dentistry as denture base materials and other industrial applications. One of the main drawbacks of these materials is the residual monomer ...
Doping of TiO2 nanotubes with nitrogen by annealing in ammonia for visible light activation: Influence of pre- and post-annealing in air
(Elsevier Science Sa, Lausanne, 2019)
The similar to 60 nm wide and similar to 2 mu m long TiO2 nanotubes were obtained by anodization of Ti films sputtered on F-doped tin oxide glass. For N-doping the samples were annealed in ammonia atmosphere. The effect ...
The influence of alumina particle modification on the adhesion of the polyacrylate matrix composite films and the metal substrate
(Taylor & Francis Ltd, Abingdon, 2019)
Adhesion behavior between the composite films, consisting of UV cured Bis-GMA (Bisphenol A glycidylmethacrylate)/TEGDMA (triethylene glycol dimethacrylate) as a matrix and the ferrous oxide doped alumina particles, Al2O3 ...
