Tube for obtaining crystals in a laboratory furnaces
(Maik Nauka/Interperiodica/Springer, New York, 2011)
A model of an air-cooled tube with a number of movable plugs, installed in a laboratory tube furnace is presented. The setup (modular "crystallization shelf-comb") allows easy regulation and simultaneous crystallization ...
Simultaneous Crystallization Testing in a Laboratory Furnace
(American Laboratory, 2011)
The cooler allows easy regulation of simultaneous crystallization tests of different crystallization parameters and substances, with the purpose of obtaining crystals from a family of newly synthesized compounds with a ...
Short-circuit oxygen diffusion in thermally grown silica layer
(World Scientific Publ Co Pte Ltd, Singapore, 2010)
Amorphous polymer-derived Si-C-N ceramics can be doped with different elements (Al, B etc.) through various pre-ceramic polymer routes. Thus, controlling of the high temperature oxidation resistance can be achieved on an ...
Influence of process parameters on the photodegradation of synthesized azo pyridone dye in TiO2 water suspension under simulated sunlight
(Taylor & Francis Inc, Philadelphia, 2011)
Photocatalytic degradation of synthesized azo pyridone dye (5-(4-sulpho phenylazo)-6-hydroxy-4-methyl-3-cyano-2-pyridone), in aqueous solutions by simulated sunlight in the presence of commercial TiO2, Aeroxide P25, was ...
Synthesis, magnetic, thermal and structural properties of Co(II), Ni(II) and Cu(II) complexes containing isophthalato ligands
(Elsevier, Amsterdam, 2011)
A series of novel ternary Co(II), Ni(II) and Cu(II) complexes containing 2,2'-dipyridylamine (dipya), 2,2'-bipyridine (bipy), and 1,10-phenanthroline (phen), as aromatic diamine ligands, and dianion of isophthalic acid ...
Carbon Monolith Surface Chemistry Influence on the Silver Deposit Amount and Crystallite Size
(Polish Acad Sciences Inst Physics, Warsaw, 2011)
The surface of carbon monolith (CM) was chemically treated in order to obtain antibacterial filters with silver deposit for water treatment. The chemical treatment involved submerging the as-received CM in HNO(3), KOH and ...
Solvent Effects on the Structure-Property Relationship of Some Potentially Pharmacologically Active 3-(4-Substituted Benzyl)-5-Ethyl-5-Phenyl- and 3-(4-Substituted Benzyl)-5,5-Diphenylhydantoins
(Springer/Plenum Publishers, New York, 2011)
Two series of 3-(4-substituted benzyl)-5-ethyl-5-phenyl- and 3-(4-substituted benzyl)-5,5-diphenylhydantoins were synthesized and their UV absorption spectra were recorded in the region 200-400 nm in selected solvents of ...
Evaluation of the Lipophilicity and Prediction of Biological Activity of Some N-Cyclohexyl-N-Substituted-2-Phenylacetamide Derivatives Using RP-TLC
(Akademiai Kiado Zrt, Budapest, 2011)
The chromatographic behavior of N-cyclohexyl-N-substituted-2-phenylacetamides was investigated using reversed phase thin-layer chromatography (RP-TLC). RP-TLC was performed on a C-18 bonded phase with different aqueous ...
