purpose: to develop a nanofibrous polycaprolacton (pcl) substrate for limbal stem cell (lsc) expansion that can serve as a potential alternative substrate to replace human amniotic membrane. methods: the human limbal stem cells (lscs) were used to evaluate the biocompatibility of substrates (nanofibrous scaffold, and human amniotic membrane) regarding cellular phenotypic profile, viability, pro...

Membrane engineering can offer an important contribution in realizing sustainable industrial development. It provides opportunities to redesign the conventional process of engineering in the logic of Process Intensification. Relatively new and less exploited membrane operations offer innovative solutions to the scarcity of raw materials, freshwater and energy. Here, we identify the most interes...

As a consequence of the increase in reverse osmosis (RO) desalination plants, number discarded RO modules for 2020 was estimated to be 14.8 million annually. Currently, these are disposed nearby landfills generating high volumes waste. In order extend their useful life, this research study, we propose recycling and reusing internal components modules, membranes spacers, membrane engineering dis...

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...

Using liquid membrane and, in particular, supported liquid membrane (SLM) is a novel method of separation in comparison to other methods such as adsorption, extraction and ion exchange. SLM is a combination of simultaneous extraction and disposal whose high efciency and capability is proven by many studies. So far, many researchers have utilized SLM in various scientifc...

BACKGROUND Membrane protein research is frequently hampered by the low natural abundance of these proteins in cells and typically relies on recombinant gene expression. Different expression systems, like mammalian cells, insect cells, bacteria and yeast are being used, but very few research efforts have been directed towards specific host cell customization for enhanced expression of membrane p...

objective: as a biological tissue material, amniotic membrane (am) has low immunogenicity and to date has been widely adopted in clinical practice. however, some features such as low biomechanical consistency and rapid biodegradation is limited the application of am. therefore, in this study, we fabricated a novel three-dimensional (3d) spongy scaffold made of the extracellular matrix (ecm) of ...

Several emerging technologies, such as membrane biofermentation, oxidation processes, among others, are currently attracting interest in different areas of biotechnological and chemical engineering [...]
