The Latest from Hubble
NASA has released the latest photos from the Hubble Space Telescope, which was updated with new equipment on a recent shuttle mission.
In May of this year, the Space Shuttle Atlantis delivered a new spectrograph and made some much-needed repairs to the Hubble Space Telescope. NASA has just released spectacular new photographs taken since those upgrades were made.

Getting accurate IR spectra on monolayer of molecules
April 18th 2024Creating uniform and repeatable monolayers is incredibly important for both scientific pursuits as well as the manufacturing of products in semiconductor, biotechnology, and. other industries. However, measuring monolayers and functionalized surfaces directly is. difficult, and many rely on a variety of characterization techniques that when used together can provide some degree of confidence. By combining non-contact atomic force microscopy (AFM) and IR spectroscopy, IR PiFM provides sensitive and accurate analysis of sub-monolayer of molecules without the concern of tip-sample cross contamination. Dr. Sung Park, Molecular Vista, joined Spectroscopy to provide insights on how IR PiFM can acquire IR signature of monolayer films due to its unique implementation.
