Reactions of transition metal carbonyl anions with 2-(1-bromoalkylidene)thiazolidin-4-ones: halogenophilic attack or deprotonation
(Oxford : Pergamon-Elsevier Science Ltd, 2011)
Bromophilic attack by the transition metal carbonyl anion, [Re(CO)(5)]Na (pK(a) = 21.1), on 2-(1-bromoalkylidene)thiazolidin-4-ones is significantly faster than abstraction of an acidic lactam hydrogen (pK(a) similar to ...
Porotic paradox: distribution of cortical bone pore sizes at nano- and micro-levels in healthy vs. fragile human bone
(Springer, Dordrecht, 2017)
Bone is a remarkable biological nanocomposite material showing peculiar hierarchical organization from smaller (nano, micro) to larger (macro) length scales. Increased material porosity is considered as the main feature ...
Characterization of a low cost Lagenaria vulgaris based carbon for ranitidine removal from aqueous solutions
(Elsevier, 2017)
Practical aspects of Lagenaria vulgaris shell conversion to activated carbon were examined along with its use in ranitidine adsorption. Kinetics and isotherms of adsorption onto Lagenaria vulgaris carbon (LVC) were correlated ...
Decolorization of textile dyes and effluents using potato (Solanum tuberosum) phenoloxidase
(Elsevier Sci Ltd, Oxford, 2012)
Potatoes are desirable source for polyphenol oxidase (PPO, EC 1.14.18.1) purification because this enzyme can be purified from the food industry waste such are potato peels from potato chips industry. This paper presents ...
The spectroscopic (FT-IR, FT-Raman, C-13, H-1 NMR and UV) and NBO analyses of 4-bromo-1-(ethoxycarbonyl)piperidine-4-carboxylic acid
(Oxford : Pergamon-Elsevier Science Ltd, 2015)
In this work, we will report a combined experimental and theoretical study on molecular and vibrational structure of 4-bromo-1-(ethoxycarbonyl)piperidine-4-carboxylic acid (BEPA). BEPA has been characterized by FT-IR, ...
Fitness traits of Drosophila melanogaster (Diptera: Drosophilidae) after long-term laboratory rearing on different diets
(Czech Acad Sci, Inst Entomology, Ceske Budejovice, 2017)
Nutrition is one of the most important environmental factors that influence the development and growth in Drosophila. The food composition strongly affects their reproduction, welfare and survival, so it is necessary for ...
ZnTiO3 ceramic nanopowder microstructure changes during compaction
(International Institute for the Science of Sintering, Beograd, 2013)
ZnTiO3 nanopowder as a constitutive component in compact production was primarily characterized. Scanning electron micrographs of as received powder were recorded. Mercury porosimetry and nitrogen adsorption were also ...
Synthesis and DNase I inhibitory properties of new benzocyclobutane-2,5-diones
(Future Medicine Ltd., 2019)
Eight new benzocyclobutane-2,5-diones (1a–1h) were synthesized, and their inhibitory properties
against bovine pancreatic DNase I were examined in vitro. Methods & results: Compounds 1a–1h
were synthesized using ...
Identification of NQO1 and ferrochelatase as interaction partners for neuroprotective N-{[2-(4-phenyl-piperazin-1-yl)-ethyl]-phenyl}-arylamides
(Wiley, Hoboken, 2018)
Affinity chromatography was used to identify potential cellular targets that are responsible for neuroprotective activity of N-{[2-(4-phenyl-piperazin-1-yl)-ethyl]-phenyl}-arylamides. Active and inactive representatives ...
Structural and fractal characterization of tungstophosphoric acid modified titanium dioxide photocatalyst
(Oxford : Pergamon-Elsevier Science Ltd, 2017)
This article presents the comparison of structural and fractal properties of nanocrystalline titanium dioxide (TiO2) and TiO2 modified with tungstophosphoric acid (TiO2/HPW) and their impact on the photocatalytic degradation ...
