Ah, yes! The world was utterly lost without a 150-row #spreadsheet of #knife #steels 🤔🔪. Who knew so many people were crying into their soup about #edge #retention and corrosion resistance? Now you, too, can spend hours debating the merits of CPM-S30V versus VG-10 instead of actually cutting anything. 🍴🤷‍♂️

/2 #photography #construction #steels A long time ago, I was 'trade'. Contractor & ltd. company. Loved every minute. I know exactly what's occurring here. The #HenryVII visitors, study centre (bloody #Tudors!) & 'community' centre. Another tourist honeypot in the centre of #Pembroke. Squillions of £'s, now overrunning, over budget and for the benefit of whom pray tell?

Promising material for a #SpaceElevator 🚠 : #Graphene in the form of a nearly transparent (to visible light) one #atom ⚛️ thick sheet. It is hundreds of times stronger 💪 than most #steels by weight https://en.wikipedia.org/wiki/Single-layer_materials#C:_graphene_and_graphyne

The invisibility 🔬 of the two-dimensional material structure was a problem for #quality assurance, now tackled by the #Universities of #Amsterdam, #NewYork and the #Spanish National Research Council (#CSIC) 📆 18 March 2023 https://www.nature.com/articles/s41467-023-37222-4
