ASM Student camps

Edit: This post was originally written a long while ago, back in the spring of 2020. I certainly was under the assumption that summer 2021 would be back to some sort of pre-Covid normal. As of today (1/18/21) the student camp schedule for 2021 has not been posted yet. It looks like the 2021 teacher camp schedule is planned to be fully virtual for 2021 (as it was in 2020), but I have no knowledge beyond what those webpages show.

It's that time of year when many students (and teachers) are starting to plan out the summer.

For teachers, I'll heartily recommend the ASM teacher materials camps. I've posted about them before.

I've also posted about the ASM student materials camps, too, but I've posted much less frequently about them - both because there are fewer of them and because I haven't ever been personally involved in those camps.

I thought I'd take a post today to rectify that and give you a whole bunch of student camp resources.

There's a video about what went on at the Eisenman camp in 2012. The Eisenman is the only ASM student camp that takes place at the ASM headquarters near Cleveland, OH, but there are about twenty other locations (appropriately, as of the summer of 2020) around the country.



This video goes through - as the title suggests - some of the legacy of the first ASM materials camp for students, the Eisenman at the ASM headquarters. They talk to some of the mentors, some former attendees who are now mentors, and ASM trustees about the history of, goals of, and - well - legacy of the Eisenman camp.



The ASM folks also interviewed some of the student attendees at the Eisenman camp one summer (including Lucas, who your friendly, neighborhood blogger was lucky enough to have taught at Princeton HS.). They, in the long run, offer probably the greatest testimonials as they lived the camp. The playlist (embedded above, click next video) also ends with a trio of videos showing some of the activities from the camp (metal casting, blacksmithing, and using a scanning electron microscope).


So, just what are materials camps? This video answers that both about the student and the teacher camps, focusing more on the student camps, though.

The camps are free. What do you have to lose?

Take a look at the student camp schedule for this summer - or the teacher camp schedule if that's more your speed.

The Future Of Energy Storage Beyond Lithium Ion

I've watched enough videos about renewable energy to know that one of the biggest issues with increasing our use of renewables isn't necessarily the actual energy production but rather the storage of the energy from times when it's produced to times when it's needed.

There's lithium ion storage batteries...3:15-4:05...

...flow batteries...4:10-7:50...

...pumped hydroelectric...8:15-8:40...

...energy vault (the most entertaining storage method if you ask me)...8:40-10:15...

...thermal storage...10:20-11:40...

...compressed air...11:50-12:00...

...cryogenic storage...12:00-12:15

Oh, and I absolutely love the joke at 1:28...energy storage methods all have 'serious potential'...

See, because stored energy is potential...it's funny.

12-28 - The dawn of the age of critical materials: Alex King at TEDxDesMoines

"Do you ever lie awake at night and worry that we'll run out of all the stuff that we need to make things?"

Well, I didn't used to, Alex, but your video kind of freaked me out.

If we had a little more neodymium, we could get more wind turbines running and turning...but we can't find enough neodymium.

If we could find more rhenium, we could get jet engines manufactured more easily...but we can't find enough rhenium.

If we just managed a bit more terbium and europium, we'd have better, more efficient fluorescent lights (admittedly, a likely dated fact in today's LED-lit world)...but we can't find enough terbium or europium.

If we just had a little more of a whole lot of elements, we'd be better able to make more smart phones...but we can't get enough of all sorts elements.

I feel like we've been on the 'rare earth elements are rare' train before, but it looks like we're going going to be on the hunt for a fair while.

...and the final story about the change from the bronze age is chilling - though the ending is a painfully abrupt.

The Mystery Flaw of Solar Panels

I find myself digging the shift that has taken place on the Real Engineering channel.

Brian McManus - the host of Real Engineering - has been putting in a ton of work to step up the video's quality and the content's depth. I find myself learning a whole bunch of new stuff in every video that he's posting.

In this one, McManus details the reasons that the solar energy striking most photovoltaic solar cells is only turned into electricity at a lab-tested 20% efficiency - and even lower 18% real-world efficiency.

This is due to light being reflected, the threshold energy necessary for silicon to release electrons, heat build up, adding metal contacts which block light hitting the cell itself, oxygen defects in the silicon wafers itself.

...and there's some awesome explanation (along with animation) of how p-type and n-type semiconductors are used to produce voltages in solar cells.

The Real Engineering videos do tend toward higher level concepts nowadays, but they're brilliantly cited and clearly explained.

They're good stuff, man.

The Bizarre Market for Old Battleship Steel

Oddly, I had heard that old battleship steel - from before the development of atomic/nuclear weapons - was highly valuable for non-radioactive shielding material.

This video does a great job explaining how the Trinity explosion - and subsequent open-air, atmospheric testing of nuclear weapons - polluted any steel made after those tests via the Bessemer process for producing steel from pig iron and using atmospheric air.

I did not know, however, that the battleships scuttled at Scapa Flow had subsequently been salvaged and some of the steel used in this way. (As an aside, your friendly, neighborhood blogger has visited Scapa Flow. It's gorgeous.)

And I also didn't know that the demand for this low-background steel has mostly been superseded because of the switch from Bessemer to basic oxygen steel production.

Materials For The Future - The Plant Age | Oded Shoseyov | TEDxGateway

"The stone age didn't end because we ran out of stones."

"The oil age will end long before we run out of oil."

Man, I hope that second statement is true.

In this TEDx talk, we hear about materials - collagen, humira (a drug), resilin (which I had to look up) - being produced in plant cells at scales large enough to be industrially practical.

The speaker discusses the final steps in harvesting the collagen to be 'like making pesto', but if I remember my pesto recipes from the past, the steps leading up to grinding the leaves didn't involve gene editing.

Though I could be wrong.

Aluminum =/= aluminium

When I was a college student at the University of Aberdeen (I spent my junior year from Wabash overseas in Scotland, doncha know) I was admonished by one of my professors for misspelling the element aluminum. 

See, he didn't know I was an American, and I didn't know - at the time - that the Brits spelled aluminum with an extra i - aluminium.

So, just why do we spell that element differently than they do?

For a few years now I've been telling a story of the Aluminum Company of America (Alcoa) changing the name because it sounded better in their advertising back in the 1880's.

The story that Michael Quinion tells in his book Port Out, Starboard Home about the etymology of words and phrases in the English language is somewhat similar to that but isn't quite the same.

Check out the story in his book - or on Google Books here.
