A Diedrich infrared, drum-based, coffee roaster. The most common roasting machines are of two basic types: drum and hot-air, although there are others including packed-bed, tangential and centrifugal roasters. Roasters can operate in either batch or continuous modes. Home roasters are also available. [20]
The Dallara DW12 (formally named the Dallara IR-12) is an open-wheel formula racing car developed and produced by Italian manufacturer Dallara for use in the IndyCar Series. It replaced the aging Dallara IR-05 chassis in the 2012 IndyCar Series season and is to be used through the 2026 season, after which it is to be replaced by the planned ...
Diedrich Coffee, a neighborhood coffeehouse, was founded by Martin Diedrich in 1983. He took over the retail, roasting and importing facets of the family business from retiring Carl. In September 1996, Diedrich Coffee went public.
The IR-8 (1998) and IR-9 (1999) were essentially 1997 model year chassis with various update kits. [11] Jim Guthrie won Dallara's first Indy car race at Phoenix on 23 March 1997. [9] Eddie Cheever won Dallara's first Indianapolis 500 in 1998, in his Oldsmobile-powered IR-7 chassis. [12]
Each Ir center is octahedral, being bonded to 3 other iridium atoms and three terminal CO ligands. Ir 4 (CO) 12 has T d symmetry with an average Ir-Ir distances of 2.693 Å. [ 4 ] The related clusters Rh 4 (CO) 12 and Co 4 (CO) 12 have C 3v symmetry because of the presence of three bridging CO ligands in each.
Dietrich "Diedrich" Uhlhorn: Engineer, mechanic and inventor, who invented the first mechanical tachometer (1817), between 1817 and 1830 inventor of the Presse Monétaire (level coin press known as Uhlhorn Press) which bears his name.
Chlorobis(cyclooctene)iridium dimer is an organoiridium compound with the formula Ir 2 Cl 2 (C 8 H 14) 4, where C 8 H 14 is cis-cyclooctene.Sometimes abbreviated Ir 2 Cl 2 (coe) 4, it is a yellow, air-sensitive solid that is used as a precursor to many other organoiridium compounds and catalysts.
Two-dimensional infrared spectroscopy (2D IR) is a nonlinear infrared spectroscopy technique that has the ability to correlate vibrational modes in condensed-phase systems. This technique provides information beyond linear infrared spectra, by spreading the vibrational information along multiple axes, yielding a frequency correlation spectrum.
