The Handbook of Porous Silicon brings together the expertise of a large, international team of almost 100 academic researchers, engineers and product developers from industry across electronics, medicine, nutrition and consumer care to summarize the field in its entirety with 150 chapters and 5000 references. The volume presents 5 parts which cover fabrication techniques, material properties, characterization techniques, processing and applications.
Much attention was given in the past to its luminescent properties, but increasingly it is the biodegradability, mechanical, thermal and sensing capabilities that are attracting attention. The volume is divided into focussed data reviews with, wherever possible, quantitative rather than qualitative descriptions of both properties and performance. The book is targeted at undergraduates, postgraduates and experienced researchers. Leigh Canham is a British scientist who has pioneered the optoelectronic and biomedical applications of porous silicon. Leigh Canham graduated from University College London in 1979 with a BSc in Physics and completed his PhD at King's College London in 1983. His early work in this area took place at the Royal Signals and Radar Establishment in Malvern, Worcestershire.
Canham and his colleagues showed that electrochemically etched silicon could be made porous. Sygic Windows Ce 5 0 Download Speed. This porous material could emit visible light when a current was passed through it (electroluminescence). Later the group demonstrated the biocompatibility of porous silicon. Canham now works as Chief Scientific Officer of psiMedica (part of pSiVida). According to the pSiVida web site, Canham is the most cited author on porous silicon.
The flow and heat transfer in a triangular enclosure filled with a fluid-saturated porous medium with a conducting thin fin on the hot vertical wall has been numerically analysed. The Darcy law model was used to write the governing equations and they were solved using a finite-difference method. Computations were carried out to analyse the effects of the Rayleigh number, length and location of fin, and thermal conductivity ratio.
Results were presented for the local and mean Nusselt numbers, streamlines, and isotherms. It was found that attaching the conductive thin fin affects the heat transfer, flow fields, and temperature distributions. It was also found that heat transfer was reduced when the thin fin was attached onto the wall.
