Titanium: atomic number: 22; weight: 47.867; Transition metal; discovery: 1791-1910—William Gregor, Martin Heinrich Klaproth, & others #Poetry #Science #History #Titanium (https://sharpgiving.com/thebookofscience/items/e022.html)

Wait till you read about how in ‘59 the properties of #Nitinol were discovered?

“One of the systems, nickel-titanium alloy, immediately exhibited considerably more [fatigue-, impact-, and heat-resistance] than the other eleven alloys. … In 1959 Buehler...named [this nickel-titanium alloy] NITINOL (Nickel Titanium Naval Ordnance Laboratory). That same year he made an observation about [NITINOL] that hinted at the extraordinary, but still undiscovered, property of Nitinol. I distinctly remember my very exciting discovery of the acoustic damping change with temperature change near room temperature.”

I used to carry hollow Korean stainless steel #chopsticks, but they aren't very strong and can get dented during transport, so I switched to solid #titanium as soon as Keith Titanium started offering them on Amazon.

In my #camping gear, I also keep a set of Bambu #bamboo chopsticks, as well as a spatula (the middle one) from Bambu's "Kids in the Kitchen" utensil set, as #cooking utensils.

I am reminded that I want to add a Snow Peak SCT-125 "foon" to my other Snow Peak #titanium utensils. I always carry the SCT-001 set (fork, spoon, knife), plus the famous SCT-004 #spork. The SCT-125 was introduced some years ago, but I never got one. The SCT-004 spork is one of the most successful #outdoor products ever; almost everyone who goes #backpacking or #camping has owned one at some point. But, the spork is not very good at pickup up #noodles, so the #foon was introduced.

Looking at others that at least make an attempt at types it most seem to just ignore the "if it isn't a valid iri" bit.

The RDF-rooted #OCaml implementation has no check in place for it in the IRI resolve and seems to just expect an IRI there https://framagit.org/zoggy/ocaml-rdf/-/blob/master/json_ld/expand.ml#L770

#Titanium does as well: https://github.com/filip26/titanium-json-ld/blob/a83ace6242ccbf7b3341f6f0a6d1993e8543d7fa/src/main/java/com/apicatalog/jsonld/expansion/ArrayExpansion.java#L94

I'm not as familiar with #Rust and they haven't marked sections, but they seem to have treated it as an optional value and not potentially invalid: https://github.com/timothee-haudebourg/json-ld/blob/master/context-processing/src/lib.rs#L252

#JsonLD

That #titanium dome from #Titan looks remarkably intact - as does the ring that it bolts onto.

No sign of the porthole, nor the composite (carbon fibre) body.

No surprise, really, but I guess that's why most normal people don't build submersibles out of carbon fibre.

"I thought it was a horrible idea(ie. composite #CarbonFiber & #Titanium hull) . I wish I’d spoken up, but I assumed somebody was smarter than me, you know, because I never experimented with that technology, but it just sounded bad on its face." - #JamesCameron, film director

@jwildeboer why am I not surprised?

I mean that vessel wasn't even closely rated for that depth....

Like even #Russia's #Titanium #Submarines struggle going 5km deep and they may be the most advanced in that field due to extensive #SeabedWarfare capabilities by #GUGI...

There's a reason why AFAIK only a #Bester #DSRV and #ROV's went around the #Titanic...

In the early 1960s, the #SovietUnion sold #titanium to the US, believing they needed it for pizza ovens, but instead they used it to build the iconic SR-71 #Blackbird Mach 3+ #spy #plane #AvGeek #aviation

Anodizing is an electrolytic passivation process used to increase the thickness of the natural oxide layer on the surface of metal parts, and different voltages leave different oxide thicknesses and thus different colors.

Another interesting #cargobike find, the Catan #titanium #cargobike with a number of innovative features. https://www.catan-bikes.com/

In Australia, Dr Tingting Song and Professor Ma Qian have been doing some incredibly clever things with 3d printing titanium. Their process removes the need for vanadium and aluminium and uses oxygen and iron instead. There's more work and testing to be done, but that's extremely exciting.

https://www.theguardian.com/science/2023/jun/01/australian-scientists-create-new-class-of-titanium-alloys

Scientists found a way to 3D print a titanium alloy family with
- manufacturer able to program to make it have different properties in different areas of the item
- use of iron and oxygen instead of other, expensive elements
- ease of recycling compared with current alloys.
Neat. #Science #Titanium #Geek #3DPrinting
