Advantages of synthetic multi-element reference material with pseudo-biological matrix in activation analysis

Recent developments in the studies of low-energy electron attachment to molecules have been reviewed in light of rate constants and cross sections obtained for various halogen-containing compounds. A rational mechanism for the initial attachment is proposed. A method for the investigation of electron thermalization in gases containing an electron-attaching compound has been presented. The electron-energy-loss rate constants and the thermalization times for some electron scavengers are derived.     

Photothermal Phase-Modulating Laser Diode Interferometer with High-Speed Feedback Control

We propose a photothermal phase-modulating laser diode interferometer equipped with a high-speed feedback control system. The CCD camera’s shutter-function raises the modulating frequency, which in turn elicits a higher feedback response, thus enabling us to eliminate nearly all external disturbance. With the recent application of a system purpose-built for discriminating between numerous fringe sequences, we have also reduced processing time.     

Use of cheaper metal than Rh, CHCl3-free Pd catalyst, in 1,2-addition of aromatic aldehydes with arylboronic acids

Pd(OAc)₂-(±)-tol-BINAP-catalyzed arylation reaction of aromatic aldehydes with arylboronic acids in the absence of CHCl₃ is described.
