As you may have noticed in your local department store, TVs are getting bigger and bigger. 4K is rapidly becoming the image standard, relegating that 1080p 3D TV your brother was bragging about to the technological scrap heap. Yesterday’s technology breakthrough is today’s technology has been. With 4K barely in the door, the industry is already talking about 8K.
I’m starting to feel like Ray Milland’s beleaguered scientist at the end of X: THE MAN WITH X-RAY EYES. Cursed with vision so acute he can now see to the end of the universe, Milland makes a last-ditch attempt to regain his sanity by plucking out his eyes. I don’t suggest anyone go that far, but the incredibly brilliant picture we are getting with new TV tech is a double-edged sword. Yes, movies and television shows look better than ever, but the picture is so good, one can’t help but be distracted by the minutiae not previously visible. I should really be paying attention to the story, not counting the leading lady’s pores or being distracted by how phony the green screen background looks. I pity fans of old movies: yes, black and white looks great in 4K, but those wrinkly cycloramas, previously a soft blur, now look as phony as the background in your daughter’s grade school play.
Sports fans are probably in heaven. I have no interest in this particular pursuit, but 4K sports telecasts catch even my attention for a few minutes. Children are certainly enraptured by cartoons in this format, but they all loved them back when everyone still had 4:3 Cathode Ray Tube sets.
The tech companies will continue to push bigger and better sets on us, but when will people start to lose interest and just go with the lower resolution versions? We haven’t reached that point yet, but I’ll bet it’s only a few years away.

Electron Beam (e-beam for short) evaporation is essentially a strong physical vapor process that allows engineers to evaporate things that are unable by resistive thermal evaporation. These things are often high-temperature elements like titanium and gold, and in some cases ceramics such as alumina, dioxide and silicon. If you’re still asking yourself what is e-beam evaporation – www.angstromengineering.com – then check out that site.
Okay, so we know why e-beam evaporation is useful, but how is it used? In short, an intense beam made up of electrons created from a filament is guided by electric and magnetic fields to collide the source material. For example, this material could be a gold pellet. Next, the pellet of gold is vaporized inside a vacuum-like closed environment.
At some point in the process, the energy transfer heats the gold pellet. By this time, the atoms from the surface will be able to separate and leave the gold where they will travel over the vacuum-like chamber. The gold atoms can then be used to cover the substrate that’s placed above all of the evaporated material. This is just one example that uses gold as the material, but there are plenty more and you can find out the best e-beam evaporation techniques that best suit your experiments.
If you’re a visual learner you may benefit from learning about e-beam evaporation from this informative video.
Here’s a summary of the video:
* Once the chosen material (for example, gold) is loaded the chamber closes. The chamber then gets down to a low pressure where electricity can be released. Magnets play a big part in directing this electricity.
* The gold is then heated up and evaporated. This process often takes just a few minutes.
* The sensor on the chamber detects the current rate of evaporation. Once the desired amount is reached, the shutter opens and the atoms are exposed to the evaporating gold. Once the required amount of metal is evaporated the shutter closes.

Mystik Radio talks about the mysterious elements that dazzle us humans on Earth. Our topic ranges anywhere between the science between magnetic materials to how to create a cassette tape. Any new cool new related to tech and science will also be gold material to chat on. Your hosts will always be Marty and Brian (me), and we’re just two nutty guys with huge curiosity in many different topics. Pretty sure we both have ADD. Marty has a degree in engineering, and I have a degree in bioscience. You might be wondering why we didn’t do anything with our degrees other than start a radio show. Well, basically we both talk way too much to be able to keep quiet and do proper work, so starting Mystik Radio was sort of our way of sticking it to the boss.
So yeah, go ahead and check out our radio station! Sometimes we’ll even put on podcasts for when we have special guests. We’re primarily located in LA, California, so holla at us if you’re ever around! If you ever have a topic in mind that you want us to talk about, just get in contact with us and we can definitely chat about it!
