Cloud Point Phenomena in the (Aniline or N,N-Dimethylaniline plus Water) Solutions, and Cosolvent Effects of Liquid Poly(ethylene glycol) Addition: Experimental Measurements and Modeling
(Amer Chemical Soc, Washington, 2015)
In this work, liquid phase behavior (cloud point phenomena) was studied for two binary and four aqueous pseudobinary systems containing aniline or N,N-dimethylaniline and poly(ethylene glycol) 200 Or poly(ethylene glycol) ...
The study of iron chlorination from bauxite for its enrichment
(Munksgaard Int Publ Ltd, Copenhagen, 2001)
The possibility of enriching bauxite by removing iron in low-temperature chlorination by gaseous chlorine in the presence of carbon as a reducer from coke and carbon monoxide, is investigated. Thermodynamic analysis points ...
Influence of Chemically Modified Short Hemp Fiber Structure on Biosorption Process of Zn2+ Ions from Waste Water
(Korean Fiber Soc, Seoul, 2014)
Short hemp fibers, acquired as a waste from textile industry, were used as an efficient biosorbent for removal of zinc ions from polluted water. In order to obtain the material with better sorption properties, short hemp ...

Hydridic and electrocatalytic properties of hypo-hyper-d-electronic combinations of transition metal intermetallic phases
(Pergamon-Elsevier Science Ltd, Oxford, 1998)
Hydridic and electrocatalytic properties of hypo-hyper-d-electronic combinations of transition metals in their intermetallic phases and alloys for the hydrogen storage, hydridic batteries and its electrode reactions (HELR) ...
Underpotential deposition of lead onto Pt(100) in acid solutions: Adsorption isotherms and interface structures
(Royal Soc Chemistry, Cambridge, 1998)
The underpotential deposition (UPD) of Pb onto Pt(100) in pure perchloric acid and in solution containing Br- was examined by classical rotating ring disk electrode (RRDPt(100)E) electrochemical methods in combination with ...
The potential of piezoelectric sensors for characterization of activated carbon cloth applied in adsorption of phenols from air
(Amer Chemical Soc, Washington, 1998)
Characterisation of activated carbon cloth (ACC) applied for phenols adsorption from the air was performed by a pair of coated piezoelectric quartz crystals as sensors. ACC cloth was impregnated with specific organic ...
Synthesis and characterization of biodegradable aliphatic copolyesters with poly(tetramethylene oxide) soft segments
(Wiley, Hoboken, 2007)
A series of aliphatic poly(ether-ester)s based on flexible poly(tetramethylene oxide) (PTMO) and hard poly (butylene succinate) (PBS) segments were synthesized by the catalyzed two-step transesterification reaction of ...
On the choice of optimal conformation in linear free-energy relationships. Reactivity of 2-[(carboxymethyl)sulfanyl]-4-oxo-4-arylbutanoic acids with diphenyldiazomethane
(Pergamon-Elsevier Science Ltd, Oxford, 2012)
Rate constants for the esterification of eleven 2-[(carboxymethyl)sulfanyl]-4-oxo-4-arylbutanoic acids with diphenyldiazomethane in ethanol at 30 degrees C were determined, and correlated with substituent constants using ...
Service life prediction for refractory materials
(Springer, New York, 2008)
Ultrasonic pulse velocity testing and image analysis were used to predict the thermal stability of cordierite-mullite refractories. Two compositions used as substrates in fast firing of porcelain whiteware, characterized ...
