The combined low-temperature, plasma/enzyme wool shrink-resist treatment
(Amer Assoc Textile Chemists Colorists-Aatcc, Res Triangle Pk, 2003)
To successfully achieve shrink resistance, an enzymatic treatment was applied to knitted fabrics previously treated with a radio-frequency low-temperature plasma. Shrink resistance was attained at the machine-washable level ...
Application of recycled-wool-based nonwoven material for purification and cleaning of water
(DWI Reports, 2003)
The investigation relates to needled fabrics produced from recycled-wool-based material (78/22 wool/polyester). Results indicate that the the sorption of lead ions is good, but each treatment does not improve the sorption ...
Methanolysis of used frying oil
(Elsevier, 2003)
The result of the investigation on methyl esters obtained on the basis of heated refined sunflower oil and used frying oils are given in the paper. Transesterification reaction conditions that affect yield and purity of ...
Crystallization behavior of alkoxy-derived cordierite gels
(Springer, New York, 2003)
Alkoxy-derived cordierite gels were synthesized from tetraethylorthosilicate (TEOS), aluminum isopropoxide (Al(OPri)(3)), and magnesium ethoxide (Mg(OEt)(2)). TEOS was partially hydrolyzed at molar ratios H2O/TEOS=1.2, in ...
Synthesis and structure determination of a chain-like aluminophosphate obtained with 1,2-diaminopropane as the structure-directing agent
(Pergamon-Elsevier Science Ltd, Oxford, 2003)
Colorless plate-like crystals (AIPO-1,2DAP) crystallize from a clear 'AlPO4-1,2-diaminopropane' reaction system. The results of elemental, thermal and FTIR analyses give the following chemical formula: (NH4+)(1,2-H(2)DAP ...
PZT ceramics obtained from mechanochemically synthesized powders
(Kluwer Academic Publ, Dordrecht, 2003)
PZT ceramics were obtained from the mechanochemically synthesized powders. Milling and sintering conditions were optimized based on results of density measurements, as well as on microstructural and electrical characterization. ...
New inorganic-organic hybrid: Synthesis and structural characterization of an alumino(oxalato)phosphate
(Amer Chemical Soc, Washington, 2003)
A new 3-D alumino(oxalato)phosphate, [H3NCH(CH3)CH2NH3](2)[Al4P6O20(OH)(4)(C2O4)(H2O)], consists of aluminophosphate layers which are pillared by oxalate anions. It contains a hybrid 12-membered channel where guest species, ...
Manganese-containing silica-based microporous molecular sieve MnS-1: Synthesis and characterization
(Amer Chemical Soc, Washington, 2003)
Manganese-containing silicalite-1 (MnS-1) was synthesized hydrothermally in the presence of the structure-directing agent (template) tetraethylammonium hydroxide (TEAOH) for the first time. The highly crystalline MnS-1 ...
The influence of heat treatment and finishing on the mechanical and dielectric properties of glass fabric-epoxy resin laminar composites
(Springer Netherlands, 2003)
The aim of this investigation was to define the optimum conditions of obtaining glass fabric - epoxy resin laminar composites with mechanical and dielectric properties that satisfy the quality needed for production of ...
Somebody get me a drill!
