Both Vickers and Knoop hardness ( H ), measured at two or more loads in the range of 100–2000 g (most commonly 100 and 500 g) for a variety of dense oxide and non‐oxide materials, covering a range of grain sizes ( G ), including single crystals where possible, were shown to generally be consistent with (often more lim…

Owing to the steric bulk of the tert-butyl groups, the reactivity of the novel porphyrin 1, which has a nonplanar macrocyclic framework, deviates distinctly from that of any other known porphyrin. For example, prolonged treatment of 1 in HClO4/MeOH leads to formation of 5,15-dihydroporphyrin (“porphodi-methene”) 2.
The triplet lifetimes of the ethynyl-bridged binuclear RuII complexes 1 (m = 0, 1; n = 1, 2) are significantly longer than that of the parent mononuclear complex, despite much lower triplet energies. This effect, which arises from electron delocalization over an extended π* orbital, decreases upon removal of the secon…
Brizziite is a new sodium antimonate mineral from the Cetine mine, Tuscany, Italy. It occurs as dense aggregates of platy {001} hexagonal crystals. Associated minerals are stibiconite and mopungite. The crystals, which are polysynthetically twinned, are colourless and transparent, with pearly lustre. Electron micropro…
