Solvent and Structural Effects on the UV-Vis Absorption Spectra of Some 4,6-Disubstituted-3-Cyano-2-Pyridones
(Springer/Plenum Publishers, New York, 2012)
A series of 4,6-disubstituted-3-cyano-2-pyridones was synthesized and their UV-Vis absorption spectra were recorded in the region 200-600 nm in the set of selected solvents. The effects of solvent dipolarity/polarizability ...
Linear Free-Energy Relationships Applied to the C-13 NMR Chemical Shifts in 4-Substituted N-[1-(Pyridine-3-and-4-yl)ethylidene]anilines
(Wiley-Blackwell, Hoboken, 2014)
Two series of 4-substituted N-[1-(pyridine-3- and -4-yl)ethylidene]anilines have been synthesized using different methods of conventional and microwave-assisted synthesis, and linear free-energy relationships have been ...
Growth, characterization and optical quality of calcium fluoride single crystals grown by the Bridgman method
(Natl Inst Optoelectronics, Bucharest-Magurele, 2016)
Calcium fluoride - CaF2 single crystals were grown using the Bridgman technique. By optimizing growth conditions, lt 111 gt -oriented CaF2, crystals up to 20 mm in diameter were grown. Number of dislocations in CaF2 ...
Cleaner and energy efficient production: a case study
(Gheorghe Asachi Technical University of Iasi, Romania, 2018)
A project called 'Cleaner Production' is conducted in the organization of the Cleaner Production Centre of Serbia at the Faculty of Technology and Metallurgy, University of Belgrade and the United Nations Industrial ...
Deep UV fluorescence imaging study of Candida albicans cells treated with gold-riboflavin hydrocolloids
(Springer, Dordrecht, 2016)
Fluorescent nanostructures were prepared by functionalization of gold nanoparticles with riboflavin molecules and used as probes for synchrotron radiation deep ultraviolet (SR-DUV) fluorescence imaging of gluteraldehyde-fixed ...
Separation of Cu(II) ions from synthetic solutions and wastewater by raw and calcined seashell waste
(Desalination Publ, Hopkinton, 2018)
The limestone and lime are agents widely used for separation of toxic metals from contaminated water. To reduce the exploitation of natural limestone deposits, appropriate replacements are sought out among the waste materials ...
Single step recovery of lipase from Penicillium cyclopium by aqueous two-phase extraction
(Taylor & Francis Inc, Philadelphia, 2016)
Recovery of lipase from Penicillium cyclopium by aqueous two-phase extraction was studied with maximal possible crude enzyme loads. In polyethylene glycol/dextran and polyethylene glycol/salt systems the influences of ...
Antimicrobial Activity of Lactic Acid Against Pathogen and Spoilage Microorganisms
(Wiley, Hoboken, 2016)
Preliminary examination of the antimicrobial activity of lactic acid against nine bacteria (Escherichia coli, Proteus mirabilis, Salmonella enteritidis, Pseudomonas aeruginosa, Staphylococcus aureus, Enterococcus faecalis, ...
Shear bond strength to dentine of dental adhesives containing hydroxyapatite nano-fillers
(Taylor & Francis Ltd, Abingdon, 2016)
The aim of this study was to compare the effect of hydroxyapatite (HAP) nano-rods (HAP rods) and HAP nano-sticks (HAP sticks) added to commercial adhesives on the macro-shear bond strength (SBS) to dentine and morphology ...
Use of up-flow percolation test to assess the environmental properties of raw and treated fly ash
(Gheorghe Asachi Technical University of Iasi, Romania, 2019)
Fly ash (FA) is a by-product created from the burning of coal in thermal power plants. FA mainly consists of mineral compounds that make them naturally caustic. Despite this, research has shown that FA may be utilized as ...
