Fun science fact 🧪🤯
Gallium is a metal that can melt in your hand literally.
It has a very low melting point of about 29.8°C, so it can turn from solid to liquid just from body heat .
That means it can look like a shiny solid spoon, but slowly turn into liquid if you hold it too long .
It’s used in electronics, semiconductors, and even LEDs ⚡💡

#MIT develops new way to recover critical metals from #EWaste
A multi-step process could produce 1.2 kilograms per day, but its viability depends on expanding #recycling efforts.
Elizabeth A. Thomson, November 24, 2025
"MIT researchers have developed a new, efficient way to recycle #gallium, #indium, and potentially other critical metals key to modern electronics from e-waste like discarded computer screens. The process could also be applied to waste streams from companies that create products containing these metals.
" 'Once optimized, our process could recover 1.2 kilograms of these metals per day,' says Antoine Allanore, a professor of metallurgy in the Department of Materials Science and Engineering. He notes, however, that this can only happen if a great deal of e-waste is recycled, and currently there are no large-scale efforts to that end. The recycling rate for gallium and indium from e-waste is currently close to 0 percent.
"The work is important because gallium and indium are listed as critical metals by the United States and the European Union. That’s because they are only produced as byproducts from the #mining of other metals like zinc and aluminum, and those mining operations, in turn, are dominated by only a few countries, including China.
"For many reasons, it doesn’t make economic sense to open new zinc and aluminum mines solely for these byproducts, says Allanore. 'Can we instead recycle and recover these two critical metals from e-waste?'
"He and colleagues have developed a multi-step process to do just that. These steps range from first physically removing #LED chips and other sources of the metals from the e-waste, to exposing them to high temperatures to liberate chemical components. Many of these steps are familiar to industry."

Галлий - металл, который плавится в руках. Температура плавления - 29.76 °C. На видео галлий взаимодействует с алюминиевым замком, через некоторое время получается крайне хрупкий сплав, который легко разрушить.
Gallium is a metal that melts in your hands. Its melting point is 29.76°C. In the video, gallium reacts with an aluminum lock, resulting in an extremely brittle alloy that can be easily destroyed.

…#criticalminerals, such as #cobalt, #lithium, #gallium and #rareearth elements like #neodymium and #yttrium, are currently being discarded as tailings of other mineral streams like #gold and zinc…
"The challenge lies in recovery," Holley said. "It's like getting salt out of bread dough—we need to do a lot more research, development and policy to make the recovery of these critical minerals economically feasible."

Unusually large quantities of antimony — a metal used in batteries, chips and flame retardants — have poured into the United States from Thailand and Mexico since China barred U.S. shipments last year. https://www.japantimes.co.jp/business/2025/07/09/us-minerals-china-export-ban/?utm_medium=Social&utm_source=mastodon #business #rareearths #china #us #trade #mining #gallium #germanium

Hey #Linux / #Mesa / #gallium folks,
I'm having a problem where I can't start any graphical user interface, whether it's wayland or x11 because the driver files given by mesa don't have the __driDriverExtensions symbol
Anyone know how to deal with this? I'm on #AlpineLinux / #AsahiLinux. If you have a lot of linux friends, feel free to boost!

#China verschärft die #Exportbeschränkungen für #Batterietechnologien und kritische Rohstoffe wie #Lithium und #Gallium.
Besonders betroffen sind Materialien für #LFP-Batterien, die in #Elektroautos und #Energiespeichern genutzt werden. Eine neue Klausel könnte Drittstaaten zwingen, sich zwischen dem US-Markt und #China zu entscheiden. Die Maßnahme ist eine Reaktion auf US-Sanktionen und könnte globale #Lieferketten weiter belasten.

#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.

I've taken the next step on my #AltKeyboardLayout #SplitKeyboard journey where I move from the #Gallium layout to the #Graphite layout. While there is not a huge difference between these two keyboard layouts, the Gallium layout has some punctuation tweaks that might make it easier to type the \( \LaTeX \) code in my lesson handouts.
It was not without some challenges to implement #graphite on my #ZSA #Voyager keyboard though -- I captured some of my journey in this blog article:

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.

@GeeTee I love my #ZSA #Voyager! I have the #Gallium layout on it now:
https://www.teachmaths.org/20241002_gallium-keyboard-layout/
I was thinking about switching to the #Graphite layout, which is pretty much the same thing except for some punctuation optimisations. To implement them on the ZSA, we need a QMK feature called "Key Overrides". I tried installing a tweaked version of the QMK firmware to enable this feature, but it causes the keyboard to crash the first time I hit any key. I'll get the the bottom of it eventually, but for now I'm pretty happy with Gallium.
BTW, I migrated my blog from #Wordpress to #Emacs #OrgMode. All the articles came across ok, but it has broken the old links, and it might take Google a little while to learn what the new links are.

The theme of National #Chemistry Week in 2024 was "Picture Perfect Chemistry". One of the recent winning "Chemistry in Pictures" in C&E News was submitted by Middle #Tennessee State #University nontraditional - but amazingly talented - Chemistry major David Kiely, whose extra-curricular laboratory #photography was supported by an American Chemical Society mini-grant from the #Nashville Local Section as part of the Tennessee #STEAM Festival. https://cen.acs.org/physical-chemistry/periodic-table/Chemistry-Pictures-Gallium-close/102/web/2024/06?ref=search_results

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.
