On 1 July 1677, the Danish navy won a decisive victory over a superior Swedish fleet in the bight of Koge. This success was partly due to trained seamen, who had been recruited in Amsterdam and manned the Danish men-of-war. Another professional seama

The thermal decomposition of BaC2O4 center dot 3.5H(2)O and BaC2O4 center dot 0.5H(2)O was investigated using in situ synchrotron X-ray and neutron powder diffraction. The decomposition routes for the barium oxalate hydrates were observed to depend o

Complex silico-ferrites of calcium and aluminium (low-Fe form, denoted as SFCA; and high-Fe, low-Si form, denoted as SFCA-I) constitute up to 50 vol pct of the mineral composition of fluxed iron ore sinter. The reaction sequences involved in the form

In the hydration of calcium aluminum oxide–gypsum mixtures, i.e., Ca3Al2O6, Ca12Al14O33 and CaSO4·2H2O, the reaction products can be ettringite, Ca6Al2(SO4)3(OH)12·26H2O, monosulfate, Ca4Al2O6(SO4)·14H2O, or the calcium aluminum oxide hydrate, C
