Optimizing nitrogen rates in Camelina sativa
Non-Peer ReviewedCamelina is a new oilseed crop to western Canada with potential applications in cosmetics, human nutrition, and biofuel. Nitrogen recommendations for camelina production in Western Canada aren’t available. Field studies were conducted in 2008 and 2009 for 10 site years at locations in western Canada to determine the effect of nitrogen rate on seed yield. Depending on the experiment, nitrogen rates ranged from 0 to 200 kg ha-1. The join point (N rate at which yields plateau) for camelina were 111 to 116 kg ha-1, which is similar to other Brassica oilseed species
Visual observations of SERRS from single silver-coated silica microparticles within optical tweezers
Surface-enhanced resonance Raman scattering (SERRS) is considerably more efficient than Raman spectroscopy, thereby enabling the detection of single molecules. Strong and short-lived SERRS emissions (<100 ms) from single, partially silver-coated, dye-adsorbed microparticles have been detected within optical tweezers (see picture). Full spectra, recorded from single particles, clearly show that the emission is due to SERRS
