Extinction Coefficient of Gold Nanostars.
Gold nanostars (NStars) are highly attractive for biological applications due to their surface chemistry, facile synthesis and optical properties. Here, we synthesize NStars in HEPES buffer at different HEPES/Au ratios, producing NStars of different sizes and shapes, and therefore varying optical properties. We measure the extinction coefficient of the synthesized NStars at their maximum surfac...

متن کاملBinomial coefficient codes over W2)
Diaconis, P. and R. Graham, Binomial coefficient codes over GF(2) Discrete Mathematics 106/107 (1992) 181-188. In this note we study codes over GF(2) which are generated for given d and r by binary vectors of the form ((y), (,‘), , ({), . , (*‘i ‘)) (mod 2), 0 <i =Z d. We describe the weight enumerators of these codes and the numbers of codewords of weights 1 and 2. These results can be used to...
متن کاملMolecular Weight, Osmotic Second Virial Coefficient, and Extinction Coefficient of Colloidal CdSe Nanocrystals
Membrane osmometry is used to measure osmotic pressures of dilute solutions containing quasi-spherical CdSe nanocrystals covered with polymer brushes in toluene in the range 31 to 45°C. Osmotic-pressure data, as a function of nanocrystal concentration, yield the molecular weight and the osmotic second virial coefficient of the nanocrystals; the latter is related to the potential of mean force b...
متن کاملExtinction coefficient measurements on clear atmospheres and thin cirrus clouds.
An experimental investigation was carried out to determine possible differences in visible light extinction properties of continental and maritime air. Urban, desert, and oceanic atmospheres were probed by means of a stable photodiode radiometer using direct sunlight as the source. No major differences were found for the three locations. Experimental coefficients generally lie slightly below mo...
