Investigation of Bubble Characteristics by Photographic Method

S. Amirzadeh; J.S Moghaddas

Volume 19, Issue 3 , September 2022, , Pages 69-80

https://doi.org/10.22034/ijche.2023.369176.1464

Abstract
  Most industrial operating units are basically in contact with two gas and liquid phases. Bubble characteristics over the last years have been determined through different methods. In this project a mass transfer system has been designed for absorbing gas bubbles by liquid phase. The mass transfer and ...  Read More

Synthesis and Characterization of Waterglass-Based Silica Aerogel Under Heat Treatment for Adsorption of Nitrate from Water: Batch and Column Studies

E. Tohfegar; J.S. Moghaddas; E. Sharifzadeh; S. Esmaeilzadeh-Dilmaghani

Volume 16, Issue 4 , October 2019, , Pages 53-72

https://doi.org/10.22034/ijche.2019.133031

Abstract
  In this work, hydrophobic silica aerogels were synthesized using sol-gel method and drying at ambient pressure. The surface morphology, pore size, and the presence of functional groups on the surface of the nanoparticles were analyzed using FE-SEM, TGA, FT-IR, and EDX, respectively. After calcination ...  Read More

Experimental and Computational Study on Hydrodynamic of a Downscaled Mini Vessel USP Dissolution Test Apparatus II

A. Mohammadi; J. Moghaddas

Volume 16, Issue 3 , September 2019, , Pages 3-22

Abstract
  Although not listed on the United States Pharmacopeia (USP), like standard USP 2, small volume USP 2 dissolution apparatus has gained a great deal of attention, especially for cases where small amount of drug product is available for testing in research and design step or evaluations are to be made on ...  Read More

Study on diffusion coefficient of benzene and ethyl benzene vapours in nanoporous silica aerogel and silica aerogel-activated carbon composites

A. Mohammadi; J. Moghaddas

Volume 16, Issue 1 , March 2019, , Pages 1-21

Abstract
  In this study, nanoporous silica aerogel and silica aerogel-activated carbon composites have been synthesized using a water glass precursor by cost effective ambient pressure drying method. Equilibrium and kinetics of benzene and ethyl benzene adsorption on silica aerogel and its composites have been ...  Read More

Optimization of Candida rugosa lipase immobilization parameters on magnetic silica aerogel using adsorption method

Jafarsadegh Moghaddas; Leila Amirkhani; Hoda Jafarizadeh- Malmiri

Volume 13, Issue 3 , July 2016, , Pages 19-31

Abstract
  Magnetic silica aerogel in hydrophobic and hydrophilic forms were used as support to immobilize Candida rugosa lipase by adsorption method. Response surface methodology (RSM) was employed to study the effects of the three most important immobilization parameters, namely enzyme/support ratio (0.3-0.5, ...  Read More

Study on the Effect of Humidity on Electrical Properties of Copper-Silica Aerogel

N. Yasrebi; J. Moghaddas

Volume 12, Issue 2 , April 2015, , Pages 3-12

Abstract
  > Copper-silica aerogel was synthesized by the sol-gel method and was heated at 400, 500 and 600°C for 3 h in the air. The gained materials were named as sample (a), (b) and (c) respectively. Then all samples were characterized by FE-SEM, EDX and FTIR spectroscopy. For resistance measurements ...  Read More
