Surfactants at the Design Limit.
This article analyzes how the individual structural elements of surfactant molecules affect surface properties, in particular, the point of reference defined by the limiting surface tension at the aqueous cmc, γcmc. Particular emphasis is given to how the chemical nature and structure of the hydrophobic tails influence γcmc. By comparing the three different classes of surfactants, fluorocarbon,...

متن کاملThe CV at the detection limit.
lent.” However, this was true only if the results from the determination of diluted (range 75-680 zg/L) and undiluted samples (range 0-75 tgfL) were pooled. Using the data in Table 2 of Hall et al. (1), we can compare the regression lines for the concentration ranges 0-75, 75-680, and 0-680 ugfL (Figure 1). It is obvious that there are discrepancies between the two methodswithin the range 0-75 ...
متن کاملReaching the betz limit experimentally and numerically
The Betz theory expresses that no horizontal axis wind turbine can extract more than 16/27 (59.3%) of the kinetic energy of the wind. The factor 16/27 (0.593) is known as the Betz limit. Horizontal Axis wind turbine designers try to improve the power performance to reach the Betz limit. Modern operational wind turbines achieve at peak 75% to 80% of the Betz limit. In 1919, Albert Betz used an a...
متن کاملElectrokinetic trapping at the one nanometer limit.
Anti-Brownian electrokinetic traps have been used to trap and study the free-solution dynamics of large protein complexes and long chains of DNA. Small molecules in solution have thus far proved too mobile to trap by any means. Here we explore the ultimate limits on trapping single molecules. We developed a feedback-based anti-Brownian electrokinetic trap in which classical thermal noise is com...
