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.

Making Science Public: Data-sharing, Dissemination and Public Engagement with Science
How have social media changed the nature of the scientific debate among scientists? Are they challenging the supremacy of editors, reviewers and science communicators? How have they impacted on engagement with the public understanding of science? Journals and peer-reviewed publications are still the most widely used channels through which research is disseminated within the scientific community and to a broader audience. However, social media are increasingly challenging the supremacy of editors

Poem "And if it snowed..." by Simon Armitage (read by Tom O'Bedlam)
Simon Armitage is from Huddersfield in Yorkshire. The poem is about everyday events related in the everyday speech of the working-class of this northern town, which gives it a gritty realism. I'm trying to give the impression of a Yorkshire accent. The phrases look like cliches but they're not - their familiarity punches the message home. People do good things and bad things. The good things he did were long term and planned. The bad things he did were brief, impulsive lapses from his us

After the Second World War, the commander of the allied occupation of Japan (1945–52), General Douglas MacArthur, proclaimed in a September 1945 interview with the New York Times that ‘Japan will never again become a world power'; and, five years later, his economic experts advised that ‘the Japanese economy's best course in the postwar era would be to make “knickknacks” – their word – for underdeveloped countries’ (Fingleton, 1997, pp. 1–2). Today, Japan is a technol

Automated Architecture: Why CAD, Parametrics and Fabrication are Really old News
Automation is transforming a significant number of industries today. This paper discusses how the Design and Construction industry is also entering into a new era of automation. In the paper I observe that designers are automating by using parametric tools (BIM, scripting, etc.) while contractors are moving into pre-fabrication and modularization. Both conceptualizations are incomplete. The paper presents how we are in the first steps of creating learning algorithms that develop specific intell
