Ultrasonic and thermal properties of γ-irradiated low-density polyethylene
(
John Wiley & Sons, Inc.
, 1993 , Article)
The ultrasonic pulse-echo technique and differential thermal analysis were utilized to characterize and to monitor the effect of ?-irradiation on the sonic modulus and the heat effect of low-density polyethylene. The sonic ...
Photodegradation of methylene blue dye by the UV/H2O2 and UV/acetone oxidation processes
(
Elsevier B.V.
, 2005 , Article)
The photodegradation of methylene blue (MB) dye in aqueous solutions was investigated using a laboratory-scale UV lamp in the presence of hydrogen peroxide (H2O2). Different initial concentrations of dyes (10, 20, 30, 40 ...
Properties of Dialkylcarbonate + 1-Alkanol Mixtures at the Vacuum Interface
(
American Chemical Society
, 2016 , Article)
The properties of solutions formed by dialkylcarbonate + 1-alkanol solutions are studied using classic molecular dynamics simulations. The effects of solution composition, temperature, and dialkylcarbonate type have been ...
Advances in Tailoring Resorcinol-Formaldehyde Organic and Carbon Gels
(
WILEY-VCH Verlag
, 2011 , Article)
An overview on the preparation and properties of resorcinol-formaldehyde (RF) organic and carbon gels reveals the fascinating and remarkably flexible properties of RF carbon and organic gels and how these properties are ...
Representation of Adsorption Data for the Isopropanol-Water System using Neural Network Techniques
(
WILEY-VCH Verlag
, 2005 , Article)
Molecular sieves and palm stone, a newly developed bio-based adsorbent, were used to break an azeotropic isopropanol-water system via an adsorptive distillation process. Equilibrium data at different inlet water contents ...
Insights into Tris-(2-Hydroxylethyl)methylammonium Methylsulfate Aqueous Solutions
(
WILEY-VCH Verlag
, 2012 , Article)
We report herein a combined experimental–computational study on tris-(2-hydroxylethyl)methylammonium methylsulfate in water solutions, as a representative ionic liquid of the aqueous-solution behavior of hydroxylammonium-based ...
Operational modeling of multistream heat exchangers with phase changes
(
Wiley Subscription Services, Inc., A Wiley Company
, 2009 , Article)
Multistream heat exchangers (MSHE) enable the simultaneous exchange of heat among multiple streams, and are preferred in cryogenic processes such as air separation and LNG. Most MSHEs are complex; proprietary and involve ...
Adaptive and Predictive Control of Liquid-Liquid Extractors Using Neural-Based Instantaneous Linearization Technique
(
WILEY-VCH Verlag GmbH & Co.
, 2006 , Article)
Nonlinearity of the extraction process is addressed via the application of instantaneous linearization to control the extract and raffinate concentrations. Two feed-forward neural networks with delayed inputs and outputs ...
Dynamic behavior of mixer-settlers
(
Wiley Subscription Services, Inc., A Wiley Company
, 1990 , Article)
A mathematical model has been developed to simulate and predict the dynamic behavior of liquid extraction counter current operations in mixer-settler units. Murphree efficiency has been included in the model. The behavior ...
Mathematical model for predicting sludge accumulation in septic tanks based on operational parameters: effect of hydraulic mixing
(
John Wiley & Sons, Ltd.
, 2015 , Article)
Reporting sludge accumulation in septic tanks as a constant rate is no longer accepted, and there is a need for a model that predicts sludge accumulation in septic tanks taking into consideration the continuous consumption ...
