Laser Experiments Reveal New Insights into Metal Core at Center of Earth
EDINBURGH, Scotland, July 11, 2018 — Using high energy laser beams and optical sensors, a scientific team from the University of Edinburgh conducted experiments to replicate conditions at the Earth’s core. Scientists observed the behavior of nitrogen samples at more than one million times normal atmospheric pressure and at temperatures above 3000 C. To do so, the team combined static and dynamic techniques in single-pulse laser heating experiments on precompressed N2 samples in a diamond anvil cell, with in situ
Mergers, Acquisitions and More
Aug 4, 2014 — June 2013 through May 2014 Just a few short months ago, our January issue included a feature titled “Where the Jobs Are Now” by Howard Rudzinsky, who noted that the U.S. had experienced 44 months of continuous job growth with a comeback...
Tiny probes dramatically boost Raman signals
ST. LOUIS – Novel gold nanoparticles can goose the signal from Raman reporters, or molecules whose jiggling atoms respond to a probe laser by scattering light at characteristic wavelengths. The discovery could lead to better-targeted drug delivery and deeper...
Tiny Probes Dramatically Boost Raman Signals
ST. LOUIS, Nov. 26, 2012 — Novel gold nanoparticles can goose the signal from Raman reporters, or molecules whose jiggling atoms respond to a probe laser by scattering light at characteristic wavelengths. The discovery could lead to better-targeted drug delivery and deeper...
Spectroscopy Optimizes Fluorescent Probes for DNA Study
HOUSTON, Sept. 7, 2012 — Time-resolved spectroscopy plus careful calculations can optimize photoluminescent probes for studying DNA, with results nearly twice as good as standard fluorescence spectroscopy for specific sequences, according to a new paper from Rice...
Dual-Purpose Neural Probe Enables New Capabilities
HOUSTON, June 13, 2012 — A new device that combines light delivery with a tetrode into a single neural probe may offer new ways of studying small clusters of brain cells.
Lensless Camera Fits on the Head of a Pin
ITHACA, N.Y., July 6, 2011 — Like a Brownie camera for the digital age, a novel microscopic device developed at Cornell University fits on the head of a pin, contains no lenses or moving parts, costs pennies to make and could revolutionize an array of fields from surgery to...
Procedure Produces Sharper AFM Probes
JENA, Germany, Nov. 2, 2010 — Scientists from Friedrich-Schiller-University Jena were successful in improving a fabrication process for atomic force microscopy (AFM) probe tips. Stephanie Hoeppener is working with an atomic force microscope for which a Jena research team...
Warranty Expanded
Sep 1, 2010 — Miniature-spectroscopy company Ocean Optics of Dunedin, Fla., has expanded its three-year warranty beyond its spectrometers to include light sources and other accessories. Effective July 1, light sources and sampling accessories purchased from the...
Ocean Optics Expands 3-Year Warranty
DUNEDIN, Fla., June 28, 2010 — Miniature spectroscopy company Ocean Optics announced the expansion of its exclusive three-year warranty beyond its spectrometers to include light sources and other accessories. Effective July 1, 2010, spectrometers, light sources and sampling...
Photothermal imaging detects nanorod orientation
HOUSTON – “Fluorescence vector probes and polarization-sensitive single-molecule spectroscopies have been widely used to explore the conformation dynamics of proteins in biological systems – and an ideal probe should yield high signal with low...
