VI. A new photometer

A lithium internal-standard flame photometer.

Performance characteristics of a new photometer with a moving filter tape for luminescence assay.

The performance characteristics of a new photometer that incorporated a reaction system consisting of a movable filtration tape have been studied for use with the firefly luciferase assay for adenosine 5'-triphosphate. Precision, linearity, and sensitivity are given for measuring a graded series of constant-light emitters, concentrations of adenosine 5'-triphosphate, and washed bacterial cells....

OPTIMA: A Photon Counting High-Speed Photometer

OPTIMA is a small, versatile high-speed photometer which is primarily intended for time resolved observations of young high energy pulsars at optical wavelengths. The detector system consists of eight fiber fed photon counters based on avalanche photodiodes, a GPS timing receiver, an integrating CCD camera to ensure the correct pointing of the telescope and a computerized control unit. Since Ja...

PhotoMeter: Easy-to-use MonoGraphoMetrics

MonoGraphoMetrics is the science of computing 3D measures from a single image. Several recent research activities have produced theoretical principles and practical tools for extracting 3D measures from uncalibrated photographs. These tools require that the user identifies configurations of edges, which are used to establish constraints or to identify planes in the scene. The process involved i...

Immobilization of a new (salen) molybdenum(VI) complex onto the ion-exchangeable polysiloxane as a heterogeneous epoxidation catalyst

In this study, a new recoverable catalyst for the epoxidation of olefins was developed using a layered polysiloxane as a support for immobilizing  (salen) molybdenum(VI) complex by electrostatic interaction between the surface of the solid support and the electrically charged molybdenum complex. Characterization of the heterogeneous catalyst by Fourier transform infrared, XRD,1H NMR,...
