Austenitic stainless steel
Shows the grain structure of an austenitic stainless steel NF709, observed using light microscopy on a specimen polished and etched electrolytically using 10% oxalic acid solution in water. Many of the grains contain annealing twins. NF709 is a creep-resistant austenitic stainless steel used in the construction of highly sophisticated power generation units.

Resistance spot weld in T3
Macrograph of a resistance spot weld made in two plates of 1,5 mm thickness. T3 - solution heat treatment, cold working and natural ageing. AA2024-T3 RSW x40 Keller's reagent interferential contrast Base material characterised by elongated, plastically deformed grains. Presence of dendritic grains in the weld. The line on the left is the original plates separation line. The two short lines on the right (inside the weld) are solidification cracks.
Glass-fibre reinforced polymer
15 vol % of short glass fibres are intimately mixed with the polypropylene matrix and injection moulded together. The fibre orientation reflects the flow of material into the mould. In this case, the fibres are well aligned in the outer layers of the moulding but more randomly aligned near the core.
Jominy end quench test: jet spraying of one end of the sample
Close up a steel specimen undergoing quenching during the jominy end quench test. As the water jet sprays onto the end of the hot, glowing specimen, a cold dark region spreads up the specimen. The cold region has transformed from austenite to a mixture of martensite, ferrite and pearlite. From TLP: The Jominy End Quench Test, http://www.msm.cam.ac.uk/doitpoms/tlplib/jominy/index.php
Jominy end quench test: transfer of a steel sample from furnace to water jet
Video of the transferral of a steel specimen from furnace to water jet during a jominy end quench test. The steel is held in a furnace to austenitise the microstructure at around 900° C. It is then transferred to the quenching machine where a water jet is sprayed onto the bottom of the specimen until the specimen is cool. From TLP: The Jominy End Quench Test, http://www.msm.cam.ac.uk/doitpoms/tlplib/jominy/index.php
Phase separation in solid solution upon cooling: vial projection
The vial containing a mixture of cyclohexane and aniline cooling from 35°, has been filmed perpendicular to the direction of the laser light (left to right). When the critical temperature is reached and the mixture goes from a single phase to two phases, the spot of light on the screen is disrupted as the phases separate. The spot "flickers" and then becomes totally diffuse. It will eventually form a single spot again once the transition is completed and the two chemicals have complet
24.02 Moral Problems and the Good Life (MIT)
This course will focus on issues that arise in contemporary public debate concerning matters of social justice. Topics will likely include: euthanasia, gay marriage, racism and racial profiling, free speech, hunger and global inequality. Students will be exposed to multiple points of view on the topics and will be given guidance in analyzing the moral frameworks informing opposing positions. The goal will be to provide the basis for respectful and informed discussion of matters of common moral c
Analysis of an Aquifer Test at St. Paul Island, Pribilof Islands, Alaska
This 30-page PDF was prepared by the Alaska Department of Natural Resources and provides detailed information about the water supply available on St. Paul Islands. The site presents the results of an aquifer test and estimates potential yield from current wells. Tables, diagrams and well logs are included.
Second Life Guides
These Second Life training guides have been split into three parts. Part 1 takes you through your first steps in achieving a Second Life by setting up your account and creating your avatar (your virtual persona in Second Life). Part 2 reminds you of the basic skills you require to operate in Second Life and enjoy the experience. Part 3 is about taking part in or directing groups for learning in Second Life.
Autolux 300 Slide Projector
Slide projector; grey metal housing on gunmetal grey base with red top.Two switched; one black, one white.. Maker: Autolux. Date: 1960 (circa) - from the The Betty Smithers Design Collection at Staffordshire University.
The Department of Chemical and Environmental Engineering has concerns about the lack of knowledge amongst school pupils, and their teachers, of the type of work undertaken by an Environmental Engineer. The interactive presentation was developed as part of an awareness raising exercise for aspects of Environmental Engineering. Targeted at KS3 pupils particularly in Year 9 (Y9) the themes of air/ soil/water pollution were chosen because of their links to the KS3 National Curriculum for Science ( e
Researching solutions to global water shortages
Director of the University of Nottingham’s Centre for Clean Water Technologies. Making sure the world’s population has enough drinking water is one of the biggest challenges we face today. A rapidly increasing global population, the fact that only a very small percentage of global water is available for consumption and an uneven global distribution of clean drinking water are the main problems in regard to the current global water crisis. Professor Hilal discusses these problems and some of

NASA KSNN What do plants need to grow?
By definition, a plant is a living thing that produces its own food through photosynthesis. This process uses carbon dioxide and water. Trapping light from the Sun, plants are able to change sunlight's energy into useable chemical energy. Not only is chemical energy produced, but oxygen is a by-product of photosynthesis. Plants are essential to the balance of life on Earth - and to life, as we know it, on other planets.

Energy resources: alternative energy in perspective
Alternative energy sources are seen by many people as potential solutions to the many economic and environmental challenges posed by the current dominance of world energy supply by fossil and nucler fuels. Just how realistic are these hopes? This unit summarises the technical and geographic challenges posed by each alternative source. It is left to you to judge the feasiibility of imploementing these changes against the claims for 'alternative' solutions to global energy challenges that are regu
