Preparation and Characterization of Novel Titania-Modified Ceramic Membranes

Recent Progresses in Preparation and Characterization of RO Membranes

Reverse osmosis (RO) is a water purifcation technology that uses a semipermeable membrane to remove ions, molecules, and larger particles for the production of drinking water. The frst RO membrane for seawater desalination, wastewater treatment and other applications were made of cellulose acetate. But, the polyamide thin-flm composite membrane that can tolerate wide pH...

Preparation and Characterization of a Novel Biodegradable Epoxy Resin Modified with Epoxidized Oleic Acid

The goal of this research was to study the curing behavior and biodegradability DER 736 modified with epoxidized oleic acid. In this paper we demonstrate the efficient epoxidation of oleic acid with performic acid generated in situ from formic acid and hydrogen peroxide in the presence of H2SO4 as catalyst. The highest relative epoxy yield of 61% was achieved at 40 ͦC after 10 h. DER 736 modifie...

Characterization of Commercial Ceramic and Hybrid Membranes Using Gas Permeation and Permporometry Tests

The gas separation performance of commercial ceramic Titania and hybrid silica (HybSi®) membranes was assessed using the gas permeation and permporometry methods. Results indicated that the HybSi® membranes have a hybrid surface containing regions covered by a polymeric matrix and others with inorganic pores. These membranes have high H2 selectivity, which incre...

Preparation and characterization of a novel silicon-modified nanobubble

Nanobubbles (NBs) opened a new field of ultrasound imaging. There is still no practical method to control the diameter of bubbles. In this study, we developed a new method to control the size by incorporating of silicon hybrid lipids into the bubble membrane. The range of particle size of resulting NBs is between 523.02 ± 46.45 to 857.18 ± 82.90, smaller than the conventional microbubbles. The ...
