Human exposure to arsenic can take place through ingestion, inhalation or skin adsorption. High dose of arsenic can cause acute toxic effects including gastrointestinal symptoms (poor appetite, vomiting, etc.), disturbance of cardiovascular a...

In this work, a thin-film composite polyamide membrane with antimicrobial polyhexamethylene guanidine (PHMG) was fabricated by the combination of photo-induced and chemical grafting to enhance antifouling anti-biofouling properties membrane. The surface were evaluated using field-emission scanning electron microscopy (FE-SEM) images, attenuated total reflectance Fourier transform infrared spect...

Membrane filtration technology has attracted extensive attention in academia and industry due to its advantages of eco-friendliness related environmental protection high efficiency. Polyamide thin-film composite nanofiltration (PA TFC NF) membranes have been widely used their separation performance. Non-acid-resistant PA NF face tremendous challenges an acidic environment. Novel relatively acid...

Polyimides are presently being investigated for a wide range of aeronautic, aerospace and industrial applications due to the fact that they have good thermal and chemical resistance yet are flexible. Within the realm of aerospace applications, polyimides can be employed for deployment, positioning, and vibration attenuation of large structures including thin-film membrane mirrors and gossamer a...

This paper summarizes R&D activities and progress at NORAM Engineering and the University of British Columbia (UBC) on preparation and testing of thin palladium-based membranes and their applications. Most of these activities were carried out internally at NORAM, some jointly with UBC and their spin-off company, Membrane Reactor Technology (MRT) through a wide range of projects. Key results out...
