...technique needs careful design and control of production parameters. Re-entrant parts produced using split tooling and sliding surfaces, but with increase in die cost and cycle times. Pressures depend on material and component size and geometry: 350–1500 kPa is typical for aluminium alloys using special presses. Has been successfully combined with diffusion bonding with...

...technique itself is simple. When at cruising altitude in the stratosphere the pilot opens up some pods below the wing containing “sticky pads”, which collect pieces of space dust. Back on Earth NASA use an exceptionally clean laboratory to pick the space dust from the collectors for researchers, like myself, to study. My research is based around these dust particles...

...technique of implanting a small radioactive material into a tumour which is known as brachytherapy and is used to treat certain cancers. It is noteworthy that in 1935 their daughter Irène along with her husband Frédéric Joliot were jointly awarded the Nobel Prize for Chemistry for their synthesis of new radioactive elements. 2: Rosalind Franklin [Rosalind Franklin with...
