Physicist Chad McCoy at Sandia National Laboratories’ Z machine loads sample coatings into holders. The coatings are made up of very thin layers of confectioners’ sugar from the grocers, burnt to a state called carbon black, interspersed between only slightly thicker layers of silica, which is the most common material on Earth, and baked. When Z fires, researchers will observe how well particular coatings protect objects stacked behind them.

Thermal spraying can be used to deposit metals, cermets (such as WC-Co), ceramics, polymers in layers typically 60 μm to 10 mm thick, for a wide range of engineering applications. Almost any material can be deposited so long as it melts or becomes plastic during the spraying process. Coating using blends of different materials to produce composite or graded coatings are possible. At the substrate surface, the particles form 'splats' or 'platelets' that interlock and build up to form the coating.

The WS100 Conformal coating Stripping System has been designed for complete removal & stripping of conformal coating from circuit boards.
Stripping of unwanted conformal coating from a PCB can be a simple process but depends on what conformal coating is to be removed or stripped, the area of coating to be removed, where the conformal coating is and the type of components on the board.
This perfectly blended formula uses local MBC Foods sea salt and fresh black peppercorns to create a wonderful full-bodied flavour to encase your favourite foods. MBC Foods is famous for its salt and pepper prawn recipe so we decided to make it available for you to take home and use for yourself (see recipe card inside). Can be used for prawns, squid, chicken, beef, lamb, pork or even tofu.

I'm sure everyone has seen all the professional reviews of this thing, so I'll give my personal take:
Pro:
Aesthetics: Design wise, this basically dispelled the myth that Google can't design hardware. It's pretty gorgeous, and the soft-touch coating is a joy to handle and easy to clean.
Instant on: This goes with the battery life, but the Chrome OS and the SSD hard drive really eliminates any lag between you and the internet.
Battery life: Serious 6-7 hour of use on a charge.
Packaging: One of the most hilarious packing + safety literature I've ever seen. If you don't know what I'm talking about, go look it up.
Speakers: The speakers are surprisingly good on the Cr48. They are not going to replace external speakers, but for essentially a netbook, it sounds not too bad.
Chrome: For me personally, the "browser" OS is perfect. If Google's goal was to eliminate any lag or delay between the user and the internet, Cr48 really demonstrate it as a proof of concept.
Cons:
Touch pad: Annoying as hell to get used to... I am finally starting to get used to it. Though "right clicking" is still hit and miss for me.
Screen: The 12" screen is basically a mid to low end LCD that one would find in a netbook. The vertical viewing angles are really poor, but at least brightness is decent.
Flash movies: I'm sure you all know by now, the guts of the Cr48 is essentially a netbook. It can NOT handle 720p movies without serious stuttering.
Weight: It's less than 1" thick but almost 4lbs (3.8lb to be exact). It's not VERY heavy, but it's not light by any stretch of the imagination.
Wifi: The strange thing about this is that even though the system can sleep and wake up almost instantly, the wifi radio some times takes 5-7 seconds to wake up. Not terrible, but when you get used to the instant on, the delay seems longer that it actually is. This only happens when the laptop goes to sleep for a while. So not THAT big of an issue.
For those that are dying to get your hands on one of these, go do a search on ebay or craigslist. I see a couple locally that are going for only $500. Now, SHOULD you get it?
Well, if you want it for the collector value, go right ahead. If you want it for the 2 years worth of Verizon whisper-net, go right ahead. (Have not had a chance to test it out yet, but will soon.)
However, when you consider that if you replace a netbook's hard drive with a SSD and install chrome OS on it, you would essentially get a Cr48. Sure it won't be as sexy as a Cr48, but performance wise, you are 85% there.
Final Verdict:
Google created the Cr48 as a showcase/test bed for what the Chrome OS could be and to show how connected you can be to the internet through Google. I think it does that with flying colors. One evidence of this that my Droid X get VERY little use at home now, where as I used to use it quite a bit. I don't know how Google plans to resolve this obvious overlap of uses between Android and Chrome OS.
One thing is for sure, Cr48 gets used ALOT in my house.
Cold gas dynamic spray, CGDS (or kinetic spray) is a rapidly developing coating and manufacturing technology in which metal particles are deposited at velocities of over 700 m/s without significant melting. The severe plastic deformation of the particles on impact produces a deposit that is very dense, with low oxide content and no thermally induced tensile stresses. This image is an optical micrograph on as-sprayed Al/Ti deposits (feedstock mixture of spherical Al and irregular sponge Ti powders), showing characteristic duplex microstructure. The as-sprayed state shown consists of an Al “matrix” with larger irregular particles of sponge Ti embedded in it. As can be seen, the small Al particles have coalesced into a single mass, by plastic deformation, with just few pores being visible (porosity is less than 3%). The Al/Ti mixture was deposited using a CGDS system, build in the Institute for Manufacturing, Department of Engineering, University of Cambridge.

For the SLR category, I've found the OM series the best of the lot in terms of size, portability, affordability and most importantly, image quality.
Don't get me started on the size of the VF, its Huuuuugeeee compared to the rest.
The OM-1 is loaded with Agfa Precisa CT 100 slide film, while the OM-2 is loaded with Lucky Colour 200. So far both cameras are mid roll. I've been meaning to put the OM 135mm f2.8 through the paces soon.
I've been trying to find a balance and rotating the duo along with my M2 and Hasselblad to ensure no one is left out. Where the day's mood decides which camera gets to tag along for the day. Which probably explains why the turnaround time for each roll is so slow.
But I do enjoy every single moment with each and every one of them;)
I recently got a second KOMZ M42 Jupiter-11 and found, that the coatings are different. If the manufacturing date can be derived from the serial numbers, they are produced in 1969 and 1972. The picture was cropped, but otherwise not post-processed.
