Ultrafast reaction and fast reaction promoted by

Ultrafast response of localized electrons in a Na-NaBr melt

Ultrafast response of localized electrons in a Na-NaBr melt are experimental points while solid lines represent fitting results. Pump wavelength

Ultrafast SNP analysis by primer extension and capillary electrophoresis. Upper panel

Ultrafast spectrally resolved dynamics of two CdS tSei x nanobelts. The fluorescence image is shown in the upper left corner. Note that the broad, time-integrated photoluminescence spectrum shown on the left consists of two distinct features centered at 628 and 636 nm with vastly different dynamics that is clearly discernible in the 2D map.

Ultrafast spectroscopy of . Time-resolved spectra

Ultrafast spin precession in NiO

Ultrafast structural relaxation of the silver trimer s molecular configuration starting in the anion s linear geometry. Photodetachment by the pump pulse initiates the bending of the meanwhile neutral trimer. The probe pulse can most efficiently produce cations while the neutral s configuration is close to that of the cation, which is the equilateral geometry

Ultrafast time resolved infrared spectroscopy of a Mo2-system supported by carboxylate-type ligands left in THF at r.t. The spectra are interpreted as a delocalised MLCT excited state at early times, which fully decays into , not detectable in this experiment. Reprinted with permission from Ref. .

Ultrafiltration basics.

Ultrafiltration by centrifugation. Ultrafiltration by centrifugation is particularly well suited for relatively small volumes. The solution is introduced into the upper chamber of the centrifugation cartridge, and on centrifu-

Ultrafiltration flux as a function of time of an electrocoat paint latex solution. Because of fouling, the flux declines over a period of days. Periodic cleaning is required to maintain high fluxes .

Ultrafiltration flux with a latex solution at an applied pressure of 60 psi as a function of feed solution latex concentration. These results were obtained in a high-turbulence, thin-channel cell. The solution recirculation rate is shown in the figure

Ultrafiltration membranes are rated on the basis of nominal molecular weight cut-off, but the shape of the molecule to be retained has a major effect on retentivity. Linear molecules pass through a membrane, whereas globular molecules of the same molecular weight may be retained. The table shows typical results obtained with globular protein molecules and linear polydextran for the same polysulfone membrane
