Excavation of an early 17th-century glassmaking site at Glasshouse, Shinrone, Co. Offaly, Ireland

An archaeological research excavation was conducted in the area immediately surrounding an upstanding glassmaking furnace near Shinrone, Co. Offaly, Ireland. It dates to the early to mid 17th century and was built and operated by French Huguenots, probably de Hennezells (de Hennezel/Henzeys/Hensie) who had settled in this region as part of the Crown plantation of King’s County (now Co. Offaly). This furnace, which employed wood rather than coal as a fuel, is a very rare survival, with no other upstanding examples known in Ireland, Britain or the Lorraine region of France where the form probably originated

ESR spectra of fluorine-containing radicals of phosphorus and arsenic

ESR spectra observed at 120 K in γ-irradiated solid solutions of PF_5 in neopentane and AsF_5 in SF_6 are ascribed to the radical ions PF_5^− and AsF_5^− in which the unpaired electron interacts strongly with the central nucleus and with four equivalent ^(19)F nuclei. Hyperfine interaction with the fifth ^(19)F nucleus was not resolvable in either case. The spectra were quite distinct from those of the tetrafluorides PF_4 and AsF_4, thus eliminating the possibility that they were due to tetrafluoride radicals undergoing rapid intramolecular ^(19)F exchange

Gold potential of the Dalradian rocks of north-west Northern Ireland : prospectivity analysis using Tellus data

The Dalradian terrane in the north-west of Northern Ireland is prospective for orogenic vein-hosted gold mineralisation with important deposits at Curraghinalt and Cavanacaw. New geochemical and geophysical data from the DETI-funded Tellus project have been used, in conjunction with other spatial geoscience datasets, to map the distribution of prospectivity for this style of mineralisation over this terrane. A knowledge-based fuzzy logic modelling methodology using Arc Spatial Data Modeller was utilised. Four main groups of targets were identified, many close to known occurrences in the Lack - Curraghinalt zone and others in prospective areas identified by previous investigations. Additional targets are located along west-north-west trending linear zones at the eastern end of the Newtownstewart Basin and to the north of the Omagh-Kesh Basin. These zones may be related to major structures linked to a westward extension of the Curraghinalt lateral ramp which is regarded as an important control on the location of the Curraghinalt deposit

2-pyridyinitrene from tetrazolo[1,5-a]pyridine and Pyrido[2,3-a][1,2,4]oxadiazol-2-one

Flash vacuum thermolyses of tetrazolo[1,5-a]pyridine and pyrido[2,3-a][1,2,4]oxadiazol-2-one generate 2-pyridylnitrene, which was detected by Ar matrix ESR spectroscopy. The thermolysis products are 2-aminopyridine, Z- and E-glutacononitriles, and 2- and 3-cyanopyrroles. The products are formed in the same ratios from the two precursors
