Investigating Mass Transfer and Reaction Engineering Characteristics in a Membrane Biofilm Using Cupriavidus necator H16
Friday, December 22, 2023
Membrane biofilm reactors are a growing trend in wastewater treatment whereby gas-transfer membranes provide efficient bubbleless aeration. Recently, there has been a growing interest in using these bioreactors for industrial biotechnology using microorganisms that can metabolise gaseous substrates. Since gas fermentation is limited by the low solubilities of gaseous substrates in liquid media,... .. read more..
Process modelling for industrial scale polyhydroxybutyrate production using fructose, formic acid and CO2: Assessing carbon sources and economic viability
Friday, December 1, 2023
Polyhydroxybutyrate (PHB) is a biodegradable polymer that has potential to replace petroleum-derived plastics. However, the commercialisation of PHB is hindered by high production costs. In this study, the material flow and economics of an industrial scale PHB production process using fructose, formic acid and carbon dioxide (CO(2)) as carbon sources were simulated and analysed. The lowest brea... .. read more..
Interaction between Engineered Pluronic Silica Nanoparticles and Bacterial Biofilms: Elucidating the Role of Nanoparticle Surface Chemistry and EPS Matrix
Wednesday, July 13, 2022
Nanoparticles (NPs) are considered a promising tool in the context of biofilm control. Many studies have shown that different types of NPs can interfere with the bacterial metabolism and cellular membranes, thus making them potential antibacterial agents; however, fundamental understanding is still lacking on the exact mechanisms involved in these actions. The development of NP-based approaches... .. read more..
Electric Field Tunability of Photoluminescence from a Hybrid Peptide-Plasmonic Metal Microfabricated Chip
Monday, May 16, 2022
Enhancement of fluorescence through the application of plasmonic metal nanostructures has gained substantial research attention due to the widespread use of fluorescence-based measurements and devices. Using a microfabricated plasmonic silver nanoparticle-organic semiconductor platform, we show experimentally the enhancement of fluorescence intensity achieved through electro-optical synergy. Fl... .. read more..
