Open Access research which pushes advances in bionanotechnology

Strathprints makes available scholarly Open Access content by researchers in the Strathclyde Institute of Pharmacy & Biomedical Sciences (SIPBS) , based within the Faculty of Science.

SIPBS is a major research centre in Scotland focusing on 'new medicines', 'better medicines' and 'better use of medicines'. This includes the exploration of nanoparticles and nanomedicines within the wider research agenda of bionanotechnology, in which the tools of nanotechnology are applied to solve biological problems. At SIPBS multidisciplinary approaches are also pursued to improve bioscience understanding of novel therapeutic targets with the aim of developing therapeutic interventions and the investigation, development and manufacture of drug substances and products.

Efforts are being made to produce highly pressurised electrolysers to increase the overall energy efficiency by eliminating mechanical compression. However, in-depth modelling of electrolysers suggests that electrolysis at atmospheric pressure is electrically more energy efficient if parasitic energy consumption and gas losses are incorporated in both cases. The reversible cell voltage increases with increasing pressures. The electrode activation and Ohmic losses, leakage current and inevitable heat losses increase the electrolysis voltage beyond the thermoneutral voltage and consequently heat removal from the stack becomes essential. The expected gas loss at various operating pressures is incorporated to reveal the energy consumption that would occur in practice. Comparison of total energy consumption at various operating pressure up to 700 atm is performed and atmospheric electrolysers are found more efficient at all levels. Practical considerations such as corrosion, hydrogen embrittlement, operational complexity, dynamic response and cost are less favourable for pressurised electrolysers.
