7.3.1 Electroplating

Electroplating is a relatively fast process, inexpensive and simple, although fairly messy and limited in applicability. The wafer is dipped into a solution with dissolved salts of the metal (e.g. CuSO4 + H2SO4) and is connected to a negative voltage. A positive metal electrode (anode), also in the solution, completes the circuit. Anywhere that current can flow into the wafer surface, metal will be deposited. Plating has several advantages: it will deposit met

1.3.4 Bringing remote sweatshops within reach continued

Another claim made by the movement is that we are all in some way connected to a market system which effectively allows sweatshops to exist in the first place. This is about more than targeting the big brand names and linking them directly to exploitation abroad; rather, it is about piecing together the global market machinery that ties the corporate buyer, the boardroom executive, the factory owner and the consumer into a system which establishes particular lines of responsibility (Ha

Clean Brexit: why leaving the EU still makes sense [Audio]
Speaker(s): Liam Halligan, Dr Gerard Lyons | In their latest book Clean Brexit, which they will discuss at this event, Liam Halligan and Gerard Lyons offer a vision of how Britain, and the world, can make a great success of Brexit. If the negotiations go well, the UK could become an inspiration for voters elsewhere in Europe who have long demanded EU reform. Unashamedly optimistic about Britain’s future, they argue that leaving the EU provides an opportunity for the UK to re-invent its economy

4.2 Feminist perspectives: who counts as a refugee?

The UN Convention has a very narrow definition of a ‘refugee’, which does not ‘accommodate those people who are forced to leave their country of origin because of economic and/or social disruption caused by environmental, political or economic turmoil or war. These are precisely the reasons that propel most refugees from the underdeveloped South’ (Lewis, 2003, p. 327). If we examine this definition further through a feminist theoretical perspective, we can see how social policy operat

2 Black holes: a reminder

You may have previously met the formation of a black hole at the end of the life of a massive star. Accreting black holes, which were formed in this way, are members of close binary star systems.

A black hole is formed when self-gravity causes material to collapse to such high densities that the escape speed (or escape velocity) reaches the speed of light. Using Newtonian dynamics we can calculate the magnitude of the escape velocity from planet Earth (mass M E

3.6.1 Stiffness

Just how compliant does an AFM cantilever have to be to enable it to follow the undulations in a surface on an atomic scale? How can we find out? It turns out that this is easier than at first it seems.

A simple assumption we can make is that the compliance of the cantilever should be appreciably greater than that of a typical bond that holds atoms to one another. Here's one way in which a rough estimate of the stiffness (the force required to cause a given deflection) of the bonds in a
