The effect of exptl. parameters on the sensitivity of 2-dimensional NMR expts. was analyzed. A set of recommendations is provided for maximizing the sensitivity of a given expt. in terms of parameters such as sampling rates, acquisition times, and weightin ...
Calibration is the first step in the prediction of concentrations from spectral measurements of chemical reaction systems. It is a well-known fact that the species in the calibration set must include those in the new set. Typically, the calibration set is ...
A rapid synthesis of aryl triflate and aryl nonaflate was developed using 4-nitrophenyl triflate and 4-nitrophenyl nonaflate as perfluoroalkanesulfonyl transfer reagents in combination with polymer supported 1,5,7-triazabicyclo[4.4.0]dec-5-ene (PTBD). Simp ...
This paper investigates the recognition of group actions in meetings by modeling the joint behaviour of participants. Many meeting actions, such as presentations, discussions and consensus, are characterised by similar or complementary behaviour across par ...
We have studied the luminescence of narrow quantum wires at photoexcitation densities of up to similar to 3 x 10(6) cm(-1). We show that even at these densities, which are well above the expected Mott density of 8 x 10(5) cm(-1), excitonic recombination do ...
We explain how to forge public parameters for the Digital Signature Standard with two known messages which always produce the same set of valid signatures (what we call a collision). This attack is thwarted by using the generation algorithm suggested in th ...
This paper describes a 1 to 3.5 kWe hermetic scroll expander generator modified from a standard hermetic compressor, an organic Rankine cycle test facility built to test expanders up to 10 kWe and a set of experimental results using HFC 134a in the dry vap ...
