Sum Frequency Generation Spectroscopy(SFG) is a technique used to analyze surfaces and interfaces. This spectroscopy method utilizes sum frequency generation, where two light beams mix at a surface and generate an output beam with a frequency equal to the sum of the two input frequencies. From the experiment setup and the output beam, one can deduce the composition, orientation distributions, and some structural information of molecules on a surface. SFG has advantages in its ability to be monolayer surface sensitive, ability to be performed in situ(for example aqueous surfaces and in gases), and not causing much damage to the sample surface.  3, record 3, English, - sum%2Dfrequency%20generation

Chaque rayon tourne dans un sens différent et donc, selon l'état de rotation du système, le déphasage entre les rayons est sensible à l'accélération angulaire du dispositif.

Determination of the effective opening size, d_w, FIH. The effective opening size of a geotextile, d_w, is determined by wet sieving quartz sand of known composition using modified sieving equipment. The geotextile functions as a sieve.... The test sample,(diameter 18 cm), is clamped into a sieve frame. The sand, which has a dry weight of 100 g for wovens and a dry weight of 300 g for non-wovens, is then sprinkled onto the sample. The sand is then sprayed continuously with water and sieved for 15 minutes in a modified sieve machine with a vertical amplitude of 3 mm at a frequency of 50 Hz. The sand which passes through the geotextile sample is caught on a paper filter and then analyzed with [different sieves].... The effective opening size, d_w, is found from the coarsest sand fraction which has passed through the test sample and in which there is still a defined quantity in relation to the original fraction.  4, record 9, English, - effective%20opening%20size

A simple arrangement of two cavities in series showed the feasibility of detecting traces of one gas in another. A klystron was used to generate microwave power which was fed through a wave guide to a transmission-type cavity. Another cavity was mounted in series with and tuned to the same frequency as the first; both cavities were identical except that the second had a gas inlet and outlet ports. From this measuring cell, its microwave energy was sent to a crystal detector. By frequency-modulating the klystron with a 50-cps sine wave voltage on the repeller, a burst of energy passes to the detector each time the generator frequency equals that of the cavities. The detector current is amplified and measured with an oscilloscope. At the beginning of the run, the two cavities are filled with the nitrogen carrier gas and, if the composition in one of the cavities is changed, its electrical size will change... causing a decrease of current from the detector.  1, record 10, English, - crystal%20detector
