Land-use experiments in the Loch Laidon catchment: sixth report on stream water quality to the Rannoch Trust

This report presents and summarises data from the Stream Water Quality project instigated by the Rannoch Trust in 1992. The project is a component of the Loch Laidon Catchment land-use experiment, which is investigating the effects of differing cattle grazing regimes on the terrestrial and aquatic upland environment. Allott et al (1994) described the project rationale and background whilst progress reports (see References) have provided ongoing updates of the accumulating dataset

Multifunctionality of silver closo-boranes

Silver compounds share a rich history in technical applications including photography, catalysis, photocatalysis, cloud seeding and as antimicrobial agents. Here we present a class of silver compounds (Ag2B10H10 and Ag2B12H12) that are semiconductors with a bandgap at 2.3?eV in the green visible light spectrum. The silver boranes have extremely high ion conductivity and dynamic-anion facilitated Ag(+) migration is suggested based on the structural model. The ion conductivity is enhanced more than two orders of magnitude at room temperature (up to 3.2?mS?cm(-1)) by substitution with AgI to form new compounds. Furthermore, the closo-boranes show extremely fast silver nano-filament growth when excited by electrons during transmission electron microscope investigations. Ag nano-filaments can also be reabsorbed back into Ag2B12H12. These interesting properties demonstrate the multifunctionality of silver closo-boranes and open up avenues in a wide range of fields including photocatalysis, solid state ionics and nano-wire production

Land-use experiments in the Loch Laidon catchment: fifth report on stream water quality to the Rannoch Trust and Scottish Natural Heritage

This report summarises data collated over five years of monitoring stream water quality in part of the Loch Lai don catchment. The work is being undertaken as part of the land-use experiments instigated by the Rannoch Trust. Work is co-funded by the Rannoch Trust and Scottish Natural Heritage
