At the heart of the wind tunnel is a 6.5m long measuring cell. It’s designed to be long enough to test the effects of drafting. The measuring platform itself floats on air bearings which offer no resistance to drag. It can be turned to test at different yaw angles.
The term Nanotechnology was originally used to define any work done on the molecular scale, or one billionth of a meter. This term is now used broadly (& loosely) for anything that is really small (hence the nano Ipod). Carbon Nanotubes (CNTs) come in single walled (SWNTs), double walled (DWNTs), and multi walled (MWNTs) varieties. CNTs can best be described as a graphene sheet rolled into a one dimensional structure with axial symmetry. CNTs are one of the primary building blocks which will be critical to the Nanotechnology Revolution. CNTs have many unique and interesting properties, please visit our our applications page to find out more about CNTs.
Modular automation options further increase the productivity and throughput of the Phoenix FL. The laser cutting system is offered with the option of a Compact Tower (CT-L) and the Flexible Automation for Lasers (FA-L) developed by LVD.
Our 1999 5 series station wagon rear seats fold down flat. Got a twin size foam mattress from amazon and we did a cross country road trip. It was so comfortable. So easy.
I have a big roll of mylar that I want to adhere to thin foam to make custom side window covers, though haven’t yet and since I found the front and back on the market that is similar to what I was thinking… I wound up buying a custom front sunshade from on eBay ( https://www.ebay.com/usr/frank-motors ) and for the rear on Amazon that is a custom Autoheatshield by Protrim Inc ( https://smile.amazon.com/s?marketplaceID=ATVPDKIKX0DER&me=A1QT5T3AEM15JY&merchant=A1QT5T3AEM15JY&redirect=true )
Bill, remember that the "price" of crude oil(as well as transport fuels) is set in the interim by speculators trading on the various commodities exchanges. When the traders see a drop in consumption and a concurrent bulging of inventory, they start bidding down the futures contracts and that collapses the trading prices. A "herd effect" kicks in and you get these price swings. Ultimately, what you will end up with a a reduction in consumption in the margin, and the producers start elbowing each other to sell their product at the loss of the other guy. That then kicks the pricing structure downstairs, until one of the producers (or more) gives up and drops out. It is because of these activities at the margins that you see these large price swings in the market.
By 12 o’clock on our first day we were hungry and tired after what felt like to us that we had been walking for ever and had been overdosed with information. We inspected the map of the show and realised that we had merely covered two thirds of the first hall, and there were a further seven to visit.

Yes, al2o3, aluminum oxide when made as a single crystal is sapphire and when .05% chromium is added to it, it becomes ruby. In alumina’s polycrystaline form, it is white and not transparent at all. All measure 9 on the Moh’s scale of relative hardness.
Despite its world-class arts and educational programming, Downtown Berkeley is college central. You know what that means? The food offering centers around pizza. And beer. And ice cream. But trust us, it’s all good.
I do not specifically understand the difference between ionising and non-ionising wavelengths of light. E.g. a lot of visible light can be ionising to photovoltaic cells (and finding materials that ionise from lower wavelengths means more energy from the sun). Is ionising / non-ionising just a cut-off point in wavelength?
