8.3.3 Reactive ion etching: chlorine/argon plasma etching of aluminium

In a reactive ion etch (RIE), a chemical reaction is used to weaken the bonding of the surface of the material and assist the sputtering process. This combines the high rate and selectivity of a gas-phase etch with the directionality of a sputter etch.

For example, consider aluminium etched anisotropically by a Cl2/Ar mixed-gas plasma, which etches at up to 1 μm min−1:

  • Power pumped into the plasma breaks the gases up, rel

21L.017 The Art of the Probable: Literature and Probability (MIT)
"The Art of the Probable" addresses the history of scientific ideas, in particular the emergence and development of mathematical probability. But it is neither meant to be a history of the exact sciences per se nor an annex to, say, the Course 6 curriculum in probability and statistics. Rather, our objective is to focus on the formal, thematic, and rhetorical features that imaginative literature shares with texts in the history of probability. These shared issues include (but are not limited to)

4.2 Iron transport

It is obvious that iron must be transported around the human body. Firstly, it must be transported from the food in the gut to the places where it is required. Mostly, iron is required in the bone marrow, where red blood cells are formed. Red blood cells have a finite lifetime of about only four months, and old cells are destroyed, usually in the spleen. Iron from the destruction of these cells is then transported from the spleen back to the bone marrow to be recycled.

Iron cannot be tr

56. On Top of The Volcano (That’s Amore!)
The word volcano originally comes from the name of the Roman god of fire, Vulcan.

4.5 Copolymerization

The alloying of metals to improve their properties is widespread and although many polymers used today are relatively pure (e.g. polystyrene, nylon), an increasing number are mixtures of two or more polymers. As with metals, one reason for doing this is to increase the range of properties. The major practical problem, however, is that homopolymers blend together with difficulty and even where blends are possible, as in some thermoplastics, phase separation can occur readily.

13 Part 2: 4 Preparing for innovation

Many inventors have said that having the idea for an invention is the easy part. This is often demonstrated by the frequency of examples of simultaneous invention. At one exhibition of inventions I attended there were three separate portable ladders to escape from fires, two systems for using rainwater to flush toilets, two types of portable vehicle wheel clamp, and two methods of reducing red-eye in flash photography. In most cases of technological innovation only one of the competing techno

Richard Titmuss: forty years on [Audio]
Speaker(s): Professor Howard Glennerster | Richard Titmuss was one of the world’s leading public analysts and philosophers. He was enormously influential in shaping the post-war welfare state and created the discipline that we now call social policy. It is now forty years since he died. What would he have made of the present state of welfare? The present state of social policy? Welfare reformers frequently talk of going back to Beveridge. Should we not think of going back to Titmuss? Howard G

13 Unit summary

  1. BSE is a TSE disease of cattle that was formally recognised in 1986. It developed to epidemic proportions in the UK, reaching a peak in 1992. Although BSE is now fading away in the UK, cases have eventually turned up in many other countries.

  2. Mainly through epidemiological studies, veterinary scientists quickly established (at least to their satisfaction) that BSE was caused by the inclusion in cattle feed of ruminant-derived MBM contaminated w

Defining Architecture: Defining Information
The rapid onset of information technologies has changed ways we do things and how we view the world. Computation already pervades many aspects of daily life through subtle augmentations and by changing our tools and our professions. Moreover, information technology accelerates the pace of our activities, its speed outstripping our capacity to digest its product. The changes brought on by this deluge force its chroniclers to create new terms. Neologisms spring up daily, often only adding to the c
