Recovery of tungsten trioxide from waste diamond core drilling crowns by nitric acid leaching
(International Journal of Refractory Metals & Hard Materials, 2021)
A cost-effective and simple hydrometallurgy procedure for recycling the diamond core drilling crowns by nitric acid leaching, followed by the sodium hydroxide leaching, has been developed. The effect of temperature, nitric ...
Cytotoxicity of the gold complex based on mercaptotriazole - A comparison with the conventional cyanide electrolyte
(Journal of the Indian Chemical Society, 2021)
The study presents the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay results on human erythroleukemia K562 cell line to compare the toxicity of electrolytes based on the mercaptotriazole gold ...
Hybrid material based on subgleba of mosaic puffball mushroom (Handkea utriformis) as an adsorbent for heavy metal removal from aqueous solutions
(Journal of Environmental Management, 2021)
The alkali treated subglebal tissue of the mosaic puffball (Handkea utriformis) (Sa) and Sa modified with hydroxyapatite (Sa-HAp), obtained by successive ionic layer adsorption and reaction (SILAR) method, were used for ...
A comparative study of chromatographic lipophilicity and bioactivity parameters of selected spirohydantoins
(Taylor & Francis Inc, Philadelphia, 2020)
In this study, lipophilicity of 21 cycloalkylspiro-5-hidantoins was assessed. The overall goal of lipophilicity evaluation is preliminary investigation which should result in a decrease of the traditionally high attrition ...
Supercritical and ultrasound-assisted extracts fromPleurotus pulmonariusmushroom: chemical profiles, antioxidative, and enzyme-inhibitory properties
(Wiley, Hoboken, 2021)
Background This study provides an insight into the impact of ultrasound-assisted extraction with water as solvent (UAEW) and extraction by supercritical carbon dioxide (SC-CO2) with 5% EtOH on antioxidant and enzyme ...
On the supramolecular outcomes of fluorination of cyclohexane-5-spirohydantoin derivatives
(CrystEngComm, 2021)
The quantitative assessment of intermolecular interactions and their cooperative effects has been performed in spirohydantoin-based model compounds, 3-benzoyl-1,3-diazaspiro[4.5]decane-2,4-dione (1) and 3-(4-fluorobenzoy ...
