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 ...
Metal sorption on macroporous poly(GMA-co-EGDMA) modified with ethylene diamine
(Elsevier Science Bv, Amsterdam, 2004)
Two samples of macroporous crosslinked poly(glycidyl methacrylate-co-ethylene glycol dimethacrylate), poly(GMA-co-EGDMA), with different porosity parameters were synthesized by suspension copolymerization and modified by ...
Synthesis of nanosized calcium hydroxyapatite particles by the catalytic decomposition of urea with urease
(Cambridge Univ Press, New York, 2007)
Nanosized calcium hydroxyapatite particles were synthesized by the catalytic decomposition of urea with urease. The influence of the synthesis parameters, i.e., temperature and ratio of the reagents/urease concentrations, ...
Interface shape and distribution of solute during Vertical Bridgman growth of Al-Cu alloy
(Elsevier, Amsterdam, 2002)
Results presented in this paper contribute to investigation of the influence of solidification rate (R) and the initial concentration of solute (C-o) on the interface shape and the distribution of the solute. Solidification ...
Bulk etching rate of LR115 detectors
(Pergamon-Elsevier Science Ltd, Oxford, 2002)
The thickness of the layer of LR115 detector removed during etching was measured with a very precise instrument. Dependence of the bulk etch rate on temperature of the etching solution was investigated. It has been found ...
Electrolyte penetration through epoxy coatings electrodeposited on steel
(Pergamon-Elsevier Science Ltd, Oxford, 1995)
A.C. impedance measurements carried out on epoxy-resin elcctrocoated steels were used to determine the pore resistance of the organic film as a function of time of exposure to 3% sodium chloride solution. The thermogravimctric ...
Polymerization studies: The application of differential thermogravimetric analysis
(Wiley, Hoboken, 1993)
The application of differential thermogravimetric analysis (DTGA) to the study of polymerization mechanisms is illustrated using as examples the radical polymerization of di‐n‐alkyl itaconates and methyl methacrylate (MMA). ...
Microscopic modelling of electrothermal desorption
(The Chemical Engineering Journal and The Biochemical Engineering Journal, 1994)
A mathematical model of thermal desorption with internal electroresistive heating of the adsorbent is postulated for a single particle. Three parallel mechanisms are considered: surface diffusion, pore diffusion and thermal ...
The thermal degradation of poly(di-n-hexyl itaconate) prepared in the presence of n-dodecyl mercaptan
(Elsevier Sci Ltd, Oxford, 1993)
The preparation of poly(di-n-hexyl itaconate) (PDHI) in the presence of the chain transfer agent n-dodecyl mercaptan resulted in polymers of increased thermal stability, owing to the suppression of the number of chain ...
The corrosion behaviour of epoxy-resin electrocoated steel
(Pergamon-Elsevier Science Ltd, Oxford, 1992)
a.c. Impedance measurements carried out on epoxy-resin electrocoated steels have been used to determine the pore resistance of the organic films as a function of time of exposure to 3% NaCl solution. The time dependence ...
