1️⃣ | #Germanium: #Wundermittel oder gefährliches #Märchen?
Bei ihren Streifzügen auf Esoterikmessen begegnet Luna allerlei Unfug. Eines der Produkte, die unter #Esoteriker:innen und angeblichen #Heiler:innen beliebt sind, ist Germanium. Was es damit auf sich hat, und warum ihr einen großen Bogen darum machen solltet, lest ihr im #SkeptixBlog!

📰 | Neues im #SkeptixBlog!
Es geht zwar weder um #Germanistik noch um die #Germanen, aber im Blog geht's trotzdem #germanisch zu: Luna hat sich mit dem vermeintlichen #Heilmittel #Germanium beschäftigt und Bernd hat Neuigkeiten zur Germanischen Neuen Medizin.

...Ein deutscher Rüstungsmanager berichtete (...), die Versorgung mit Germanium, das für Nachtsichtgeräte gebraucht wird, stocke. China habe die Lieferungen "praktisch eingestellt". Auch Materialien für die Herstellung von Artilleriegranaten und Gefechtsköpfen sind demnach Mangelware, schon seit zwei Jahren schränkt die Volksrepublik den Export von etwa Vorprodukten für die Sprengstoffproduktion ein...
Random #AliExpress finding...
So today I discovered why I was getting weird results in a circuit I was testing the other day. It turns out that some of the 1N60P germanium diodes I have are fakes. They appear to be just a plain silicon diode with a forward voltage of ~0.6V, rather than the actual article's ~0.25V.
They're in the right DO-35 glass package and they've been marked as 1N60P, so someone's gone to the trouble of faking it well - but I can't see why. It can't possibly be that profitable to buy genuine silicon diodes, remark them, and then sell them for just a few pennies extra, can it?
It's not like the sellers that remark a ten-cent opamp as a $10 part - I can see how that's profitable.
Weird.

#China banned exports of a few rare #minerals to the #US. Things could get messier.
#Gallium and #germanium are used to make #semiconductors. Could battery materials be the next target?
This might be only the beginning. China is a powerhouse, and not just in those niche materials—it’s also a juggernaut in #cleanenergy, and particularly in battery supply chains. So what comes next could have significant consequences for #EV and #climate action more broadly.

Chinas jüngste Beschränkungen für den Export kritischer #Mineralien in die #USA, die auf #Gallium, #Germanium, #Antimon und #Graphit abzielen, markieren eine deutliche Eskalation im Tech-#Handelskrieg.
Dieser Schritt ist ein direkter #Gegenschlag der US-Sanktionen gegen chinesische #Halbleiter und unterstreicht die wachsende Spannung zwischen nationaler Sicherheit und wirtschaftlicher Abhängigkeit.
Die #USA müssen nun nach alternativen Quellen suchen.

Chinese curbs on exports of three niche metals to the U.S. have already rattled the market. Now, a bigger clampdown looks set to have far-reaching ramifications for American defense and chipmaking industries. https://www.japantimes.co.jp/business/2024/12/23/markets/metal-markets-chinese-clampdown/?utm_medium=Social&utm_source=mastodon #business #markets #metals #batteries #electricvehicles #semiconductors #china #mining #us #trade #tech #gallium #germanium #antimony #solar #renewables
Die #NATO hat eine Liste mit den 12 verteidigungskritischen Rohstoffen heraus gegeben. Soweit ich das sehe sind die Rohstoffe gelistet nach der Wehrwichtigkeit und nicht nach dem Versorgungsrisiko, sonst würde mich der erste Platz mit #Aluminium überraschen. Weniger überraschend sind auf jeden Fall die weiteren Rohstoffe wie #Beryllium, #Cobalt, #Gallium, #Germanium, #Graphite, #Lithium, #Manganese, #Platinum, #REE, #Titanium und #tungsten

Pricing for key chipmaking material hits 13-year high following Chinese export restrictions — #China's restrictions on #Gallium exports hit hard
China is the primary global supplier, accounting for 94% of gallium production. Prices rose to $595 per kilogram, a 17% increase over the previous level on December 11, the highest price since 2011. This sharp increase follows China's latest export ban of critical minerals to the US, including gallium, #germanium, and #antimony.

What #China’s critical #mineral ban means for the #US
In explicitly cutting off, rather than merely restricting, materials of strategic importance to the #semiconductor, #defense, and #electricvehicle sectors (#gallium, #germanium, #antimony), China has clearly crossed a new line in the long-simmering #tradewar. The nation has signaled it’s prepared to hit back harder still, in ways that could inflict serious #economic pain on its biggest economic rival.

#China bans export of key #minerals to #US as trade frictions escalate
China has banned exports to the #UnitedStates of items related to the minerals #gallium, #germanium and #antimony that have potential military applications, it said on Tuesday, a day after Washington's latest crackdown on China's chip sector.
Gallium and germanium are used in #semiconductors, while germanium is also used in infrared technology, #fibreoptic cables and #solar cells.

Projection de l’impact de l’arrêt de l’exportation de métaux critiques chinois vers les États-Unis d’Amérique, selon l’USGS
▶️ […] the researchers estimate there could be a $3.4 billion decrease in U.S. GDP if China implements a total ban on exports of gallium and germanium, minerals used in some semiconductors and other high-tech manufacturing.
