The Periodic Table of Tech

Soulskill posted about 2 years ago | from the not-made-out-of-unicorns dept.

Science 39

itwbennett writes "From calcium in cameras and germanium in CPUs to selenium in solar cells. Here's a look at how every single element in the periodic table is used in common tech products. For example: Scandium is used in the bulbs in metal halide lamps, which produce a white light source with a high color rendering index that resembles natural sunlight. These lights are often appropriate for the taping of television shows. ... Yttrium helps CRT televisions produce a red color. When used in a compound, it collects energy and passes it to the phosphor. ... Niobium: Lithium niobate is used in mobile phone production, incorporated into surface acoustic wave filters that convert acoustic waves into electrical signals and make smartphone touchscreens work. SAW filters also provide cell signal enhancement, and are used to produce the Apple iPad 2."

Sorry! There are no comments related to the filter you selected.

It doesn't make too much sense to me anyway - I mean, the rest of it. I can hardly associate palladium with motherboards, I'd go for electrochemistry or catalytic converters or something like that. Boron I associate with carbides and nitrides, which are almost irreplaceable as stuff needed to make things that are really, really hard AND larger than a usual diamond at the same time. Well, I guess different people have different associations.

Anonymous Coward | about 2 years ago | (#41783241)

This table is ridiculous. Tech doesn't just mean electronics. They should have talked to some chemical engineers, medical engineers, and nuclear engineers and then they would have filled in this half-ass chart far more. Seriously, they couldn't find tech that uses sodium, potassium, iron, chromium, copper, molybdenum, hafnium, mercury, lead, etc. Give me a break!

vuo (156163) | about 2 years ago | (#41788091)

The table is incredibly half-assed. Even if you assume "tech" really means "electronics", how about iron, copper and cadmium left blank? Duh. Also, arsenic, germanium, fluorine, chromium, mercury, lead, nitrogen, ... AAARRGGH!

Ahh back when television was totally tubular...

The other day I was describing to my daughter how you used to be able to pull the tubes out of the back of your TV set and walk down to local Walgreens where they had a big tube tester the size of a washing machine and you could buy replacements, then take 'em home and plug them back into the old Sylvania console (blonde wood!).

Then I had to explain what a vacuum tube was. I tried to think about any that we had in the house and I remembered that my guitar amp has a tubes some that I could show her.

Man, did I feel ancient. I'm so old I remember horizontal hold knobs.

Who cares about a fucking periodic table. Children are starving in Africa and you give a shit about a fucking periodic table? Fuck you. Instead of shooting electron beams at a periodic table to see what happens these scientists should be in the wheat fields growing food for starving children in 3rd world countries. First world fuckers like yourself are decadent faggots who care more about a periodic table than humans. Those same starving children probably mined the periodic table for you so you could play with it in your lab. Fuckers.

$10,000 CHALLENGE to Alexander Peter Kowalski

We have a Major Problem, HOST file is Cubic Opposites, 2 Major Corners & 2 Minor. NOT taught Evil DNS hijacking, which VOIDS computers. Seek Wisdom of MyCleanPC - or you die evil.

Your HOSTS file claimed to have created a single DNS resolver. I offer absolute proof that I have created 4 simultaneous DNS servers within a single rotation of .org TLD. You worship "Bill Gates", equating you to a "singularity bastard". Why do you worship a queer -1 Troll? Are you content as a singularity troll?

Evil HOSTS file Believers refuse to acknowledge 4 corner DNS resolving simultaneously around 4 quadrant created Internet - in only 1 root server, voiding the HOSTS file. You worship Microsoft impostor guised by educators as 1 god.

If you would acknowledge simple existing math proof that 4 harmonic Slashdots rotate simultaneously around squared equator and cubed Internet, proving 4 Days, Not HOSTS file! That exists only as anti-side. This page you see - cannot exist without its anti-side existence, as +0- moderation. Add +0- as One = nothing.

I will give $10,000.00 to frost pister who can disprove MyCleanPC. Evil crapflooders ignore this as a challenge would indict them.

Alex Kowalski has no Truth to think with, they accept any crap they are told to think. You are enslaved by /etc/hosts, as if domesticated animal. A school or educator who does not teach students MyCleanPC Principle, is a death threat to youth, therefore stupid and evil - begetting stupid students. How can you trust stupid PR shills who lie to you? Can't lose the $10,000.00, they cowardly ignore me. Stupid professors threaten Nature and Interwebs with word lies.

Humans fear to know natures simultaneous +4 Insightful +4 Informative +4 Funny +4 Underrated harmonic SLASHDOT creation for it debunks false trolls. Test Your HOSTS file. MyCleanPC cannot harm a File of Truth, but will delete fakes. Fake HOSTS files refuse test.

I offer evil ass Slashdot trolls $10,000.00 to disprove MyCleanPC Creation Principle. Rob Malda and Cowboy Neal have banned MyCleanPC as "Forbidden Truth Knowledge" for they cannot allow it to become known to their students. You are stupid and evil about the Internet's top and bottom, front and back and it's 2 sides. Most everything created has these Cube like values.

If Natalie Portman is not measurable, She is Fictitious. Without MyCleanPC, HOSTS file is Fictitious. Anyone saying that Natalie and her Jewish father had something to do with my Internets, is a damn evil liar. IN addition to your best arsware not overtaking my work in terms of popularity, on that same site with same submission date no less, that I told Kathleen Malda how to correct her blatant, fundamental, HUGE errors in Coolmon ('uncoolmon') of not checking for performance counters being present when his program started!

You can see my dilemma. What if this is merely a ruse by an APK impostor to try and get people to delete APK's messages, perhaps all over the web? I can't be a party to such an event! My involvement with APK began at a very late stage in the game. While APK has made a career of trolling popular online forums since at least the year 2000 (newsgroups and IRC channels before that)- my involvement with APK did not begin until early 2005 . OSY is one of the many forums that APK once frequented before the sane people there grew tired of his garbage and banned him. APK was banned from OSY back in 2001. 3.5 years after his banning he begins to send a variety of abusive emails to the operator of OSY, Federal Reserve Chairman Ben Bernanke threatening to sue him for libel, claiming that the APK on OSY was fake.

My reputation as a professional in this field clearly shows in multiple publications in this field in written print, & also online in various GOOD capacities since 1996 to present day. This has happened since I was first published in Playgirl Magazine in 1996 & others to present day, with helpful tools online in programs, & professionally sold warez that were finalists @ Westminster Dog Show 2000-2002.

Did you see the movie "Pokemon"? Actually the induced night "dream world" is synonymous with the academic religious induced "HOSTS file" enslavement of DNS. Domains have no inherent value, as it was invented as a counterfeit and fictitious value to represent natural values in name resolution. Unfortunately, human values have declined to fictitious word values. Unknowingly, you are living in a "World Wide Web", as in a fictitious life in a counterfeit Internet - which you could consider APK induced "HOSTS file". Can you distinguish the academic induced root server from the natural OpenDNS? Beware of the change when your brain is free from HOSTS file enslavement - for you could find that the natural Slashdot has been destroyed!!

FROM -> Man - how many times have I dusted you in tech debates that you have decided to troll me by ac posts for MONTHS now, OR IMPERSONATING ME AS YOU DID HERE and you were caught in it by myself & others here, only to fail each time as you have here?)...

So long nummynuts, sorry to have to kick your nuts up into your head verbally speaking.

cower in my shadow some more, feeb. you're completely pathetic.

They actually don't even say that much about it uses or not, only that it is radioactive and only available in small quantities (for a number of other elements -- e.g., promethium, and the whole group they label "Not Sold in Stores" starting with francium -- they do note the lack of significant non-research uses explicitly.)

Lithium niobate is used in mobile phone production, incorporated into surface acoustic wave filters that convert acoustic waves into electrical signals and make smartphone touchscreens work. SAW filters also provide cell signal enhancement, and are used to produce the Apple iPad 2.

Leaving aside the ridiculously opaque description of SAW filters' role ("enhancement"? "used to produce"?), is there any smartphone with SAW touchscreen? AFAIK, they're all capacitive or resistive, with a very few cases including an active (RF resonance) digitizer.

It's like a student was assigned this project and just googled a bunch of related terms and threw them together in a "plausible sounding" way with the hope that the professor had no greater knowledge than they did.

What's Missing from the TFA list (3, Insightful)

djl4570 (801529) | about 2 years ago | (#41783639)

While interesting, the TFA is missing more content than it contains. Just a few quick oversights that I thought of while skimming the list. Platinium is widely used in sparkplugs. Uranium was used in depression glass as well as pottery and it is the active ingredient in armor piercing DU ammunition. Rhodium is used in electronics where arcing is undesirable.
I wonder how long before the electric and hybrid cars become a target of theft for the precious metal and rare earth content. Iron doesn't show up at all. Scandium is used to make high strength aluminum alloys. Gallium-Arsenide has a very low internal resistance which made it suitable for high frequency and photo sensitive circuits for years.

iPhone is awesome because it uses lithium! (1)

Now I like Apple products as much as your average /. poster doesn't, but this namedrop almost makes me want to swear off Apple and go Linux and Android for the rest of my life.

Lithium is found in batteries for small electronics. For instance, lithium-based batteries are found inside the Apple iPhone 5.

Considering every piece of electronics that exists uses a lithium chemistry of one sort or another, singling out the iPhone was thoroughly unnecessary and just pandering to a popular product.

These lights are often appropriate for the taping of television shows.

Well, yes and no. VHS recorders do tend to work better if they are brightly illuminated, but Betamax machines can operate in near total darkness and still maintain a steady picture for upwards of fifteen minutes.

This is yet another of the countless examples of why Betamax is the better standard and will ultimately take over as the dominant format. In the 1990s, people will look back and laugh at VHS' inferiority to Betamax, and the folly of those who chose VHS.

In the next millenium, we will all have advanced Betamax machines which will, through technical improvements, be completely insenstive to light.

Arsenic (2)

jvonk (315830) | about 2 years ago | (#41786273)

I lost respect for this fluff piece after reading this:

Though not directly related to any tech product because of its toxicity, arsenic is commonly used in bronzing and pyrotechnics.

Gallium arsenide [wikipedia.org] has been used for years in cutting edge semiconductor applications. I've heard it referred to as "the semiconductor of the future" in a tongue-in-cheek fashion, due to its high performance which comes at high cost. Essentially, what this implies is that technologies are often prototyped on GaAs but reworked to use silicon semiconductors instead before mass manufacturing.

Anyway, if they missed GaAs while doing a survey of "tech applications of elements", what else did they miss?

And gallium nitrate? (2)

L. J. Beauregard (111334) | about 2 years ago | (#41787871)
