High magnification SEM image of open cell polyurethane foam
If a gas is injected into a liquid it forms a cellular foam structure. When a thermoset prepolymer of low viscosity is foamed, the polymer can drain from the cell walls (driven by surface tension) before it sets at the cell edges, leaving an open-celled foam. The cell edges have three concave sides, and some remnants of collapsed cell walls can be seen at the cell edges.
FORMGRIP closed cell aluminium foam
Additions such as SiC are made to molten aluminium or aluminium alloy to modify the melt viscosity and make it suitable for foaming. 1 to 3 wt% of pre-oxidised titanium hydride is then added to the melt which is solidified to form a precursor which can be foamed in a controlled manner by a subsequent heat treatment. The resulting foam has a relatively fine and uniform cell structure.

Life Cycle Analysis and Carbon Footprinting Session Outline
Part Three of Greening Business: Life cycle analysis is a relatively new approach to environmental management which seeks to understand the impact of all related aspects of a product or service over its whole life cycle from production to disposal. An understanding of life cycle analysis is essential to a holistic understanding of the impact of products and services and hence the environmental benefits of changes to processes. It also underpins the process of carbon footprinting.

E-portfolio learning lunch - Ben Cotton's Presentation
Staff and students are becoming increasingly aware of the potential use and benefits of e-portfolios and social media tools. Delegates will have the opportunity to explore the use of e-portfolios and social media through three case studies: Ben Cotton will provide a student / graduate trainee perspective focusing on the explosion of social media and its potential in terms of personal development, reflection, career planning and in terms of forging a career in the PR industry. Ben conducted his o

Apple Cup Rivals Contribute to Apple Genome Sequencing
PULLMAN, Wash. — An international team of scientists from Italy, France, New Zealand, Belgium and the USA have published a draft sequence of the domestic apple genome in the current issue of Nature Genetics.
The availability of a genome sequence for apple will allow scientists to more rapidly identify which genes provide desirable characteristics to the fruit and which genes and gene variants provide disease or drought resistance to the plant. This information can be used to rapidly improve
Article :: Real World Tips For Using Illustrator's Objects, Groups, and Layers
Just as there are benefits to keeping an orderly desk, there are advantages to using groups and layers for adding structure to your files. In Adobe Illustrator CS2, groups and layers not only offer a convenient way to manage objects in a file (as they did in earlier versions of Illustrator), but now they can also control the appearance of your file. Find out more in this informative chapter by Mordy Golding.
The US Industrial Growth (Pre-Civil War)
This video is accompanied by text. "In the eighteenth century, British inventors perfected a series of machines for mass production of textiles, which initiated the European Industrial Revolution and gave Britain a head start in industrial production. For many years, the British carefully guarded their industrial secrets, forbidding the export of machines or even descriptions of them and restricting the departure of informed mechanics. The British could not keep its secrets forever, and in 1789,
Introduction to Computer Science: Programming Abstractions
This course is the natural successor to Programming Methodology and covers such advanced programming topics as recursion, algorithmic analysis, and data abstraction using the C++ programming language, which is similar to both C and Java. If you've taken the Computer Science AP exam and done well (scored 4 or 5) or earned a good grade in a college course, Programming Abstractions may be an appropriate course for you to start with, but often Programming Abstractions (Accelerated) is a better choic
How can we stop cyberbullying?
The start of the new school year this fall has brought with it a national focus on and concern with cyberbullying. What is this form of bullying and how can it be addressed? University of Minnesota expert on cyberbullying Shayla Thiel-Stern, assistant professor in the U of M's School of Journalism and Mass Communication, talks about this devastating problem.
Masters EXPO 2010
The 10th Masters Expo took place on Thursday 30 September. Over 30 student projects were on display throughout the ground floor of Old Broadcasting House. The projects included work from students studying masters in the areas of music, media and computing.
The Expo allowed postgraduate students to display the work they had completed as part of their final major project, the largest component of the masters course. MSc Sound and Music for Interactive Games student, Samir Graba, found the day ver
Orchestrating cell separation in plants : what are the risks and benefits?
In this podcast, Professor Roberts from the School of Biosciences discusses his research into the mechanism responsible for regulating cell separation in plants. In particular how plants ‘shed’ parts of themselves such as leaves or fruit. Professor Roberts explores the potential application of his research, through prevention or encouraging of the ‘shedding’ process, agricultural harvests could potentially be increased or even synchronised. Professor Roberts also discusses the resistance

TALAT Lecture 3210: Continuous Casting
This lecture gives an overview about the possibilities to produce aluminium foilstock and wire-bar in a continuous way. Continuous casting is the preferred casting method in modern plants because it offers higher productivity. But there are limitations in the use of this technology because not all alloys can be cast. The product shows properties that can differ from conventional material. This lecture demonstrates the principal of operation; technologies for continuous casting; types of casters;
