Alice Far-Ultraviolet Spectrograph Reveals Electrons as Cause of Water Molecules Breakup on Comet Surface

A close-up of Comet 67P/Churyumov-Gerasimenko by NASA's ultraviolet instrument surprised scientists by revealing that electrons close to the comet's surface -- not photons from the Sun as had been believed -- cause the rapid breakup of water and carbon dioxide molecules spewing from the surface.

McPherson Introduces Extended Lifetime Deep and Vacuum Ultraviolet Wavelength Spectral Test Systems

McPherson now offers extended lifetime deep and vacuum ultraviolet (VUV) wavelength spectral test systems. The VUV instruments are ideal for analyzing doped crystalline materials, deep UV optics, and coatings. They directly measure absolute transmission and variable angle reflectance. A gas cell attachment is used for high sensitivity absorption.

Subaru Telescope Helps Conduct Spectroscopic Observations on Solar-Type Superflare Stars

A team of astronomers has used the High Dispersion Spectrograph on the Subaru Telescope to conduct spectroscopic observations of Sun-like "superflare" stars first observed and cataloged by the Kepler Space Telescope. The investigations focused on the detailed properties of these stars and confirmed that Sun-like stars with large starspots can experience superflares.

New Photon Correlation Spectroscopy-Based Method for Directly Measuring Sound Pressure

Accurate measurements of airborne sound are needed for a range of regulatory, health and safety, and commercial applications, from monitoring environmental noise to testing the performance of acoustic devices. To ensure reliable measurements of sound pressure, microphones must be regularly calibrated by measuring their sensitivity over a certain frequency range.

Ultrafast UV Two-Dimensional Spectroscopy Confirms Electron Transfer between Tryptophan and Other Molecules

Tryptophan is an amino acid, one of the building blocks of proteins. It is used extensively to study how proteins change their 3D structure, and also how they interact with other proteins and molecules. This is studied with a fluorescence technique called FRET, which measures the transfer of energy from tryptophan to another molecule.

2D IR Spectroscopy Helps Study Therapeutic Mechanism of Anti-Viral Drug

A newly developed spectroscopy method is helping to clarify the poorly understood molecular process by which an anti-HIV drug induces lethal mutations in the virus's genetic material. The findings from the University of Chicago and the Massachusetts Institute of Technology could bolster efforts to develop the next generation of anti-viral treatments.

McPherson Introduces CCD-UV Absorbance Spectrophotometer

Fast DUV Spectrophotometer
McPherson’s newest VUVAS spectrophotometer capitalizes on the speed and sensitivity of direct detection, ultraviolet sensitive CCD detectors. Faster data acquisition enables more complex data sets involving spectral response vs. temperature or time. Fast acquisition also protects against potential measurement errors due to changing sample or environmental conditions.
