Characterizing limestone rocks with Raman spectroscopy
Research published in The European Physical Journal Plus shows that it is possible to classify rocks according to the size of the particles they contain during quarrying, using a portable Raman spectrometer......»»
Discovering new energy levels in atomic hyperfine structures
Since the late 1960s, the Laboratoire Aimé Cotton (LAC) in Orsay, France, has made significant progress in the classification of complex atomic spectra. These advances have been driven both by the development of Fourier transform spectroscopy, and t.....»»
High-pressure reactions can turn nonporous rocks into sponges
In deep Earth, rocks take up and release water all the time, and the effects can be wide reaching. Dehydration can cause rocks to crack and trigger earthquakes, and over geologic timescales, this water cycling can influence plate tectonics and move c.....»»
Sources of water and hydroxyl are widespread on the moon, new analysis of maps finds
A new analysis of maps of the near and far sides of the moon shows that there are multiple sources of water and hydroxyl in the sunlit rocks and soils, including water-rich rocks excavated by meteor impacts at all latitudes......»»
X-Ray Imaging and Spectroscopy Mission unveils black hole and supernova remnant surroundings
The X-Ray Imaging and Spectroscopy Mission (XRISM) has revealed the structure, motion and temperature of the material around a supermassive black hole and in a supernova remnant in unprecedented detail. Astronomers presented the first scientific resu.....»»
Photoacoustic sensor achieves high-sensitivity detection of multiple greenhouse gases
Recently, Prof. Gao Xiaoming's team from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences, developed a novel photoacoustic spectroscopy (PAS)-based sensor that enabled simultaneous, high-sensitive detection of CO2, CH4, and.....»»

"Disappeared completely": melting glaciers worry Central Asia
Near a wooden hut high up in the Kyrgyz mountains, scientist Gulbara Omorova walked to a pile of gray rocks, reminiscing how the same spot was a glacier just a few years ago......»»
Evidence of “snowball Earth” found in ancient rocks
An outcrop in Scotland has material from when the Earth went into a deep freeze. Enlarge / Artist's conception of the state of the Earth during its global glaciations. (credit: NASA) Earth has gone through many geologic.....»»
Neural network improves tunable diode laser absorption spectroscopy quantification accuracy
A research group from the Hefei Institutes of Physical Science (HFIPS) of the Chinese Academy of Sciences recently developed a neural network-based absorbance recovery method to improve the accuracy of single path tunable diode laser absorption spect.....»»
Precariously balanced rocks in New York, Vermont provide limits on earthquake shaking
Five boulders, delivered by glacier and balancing delicately on rocky pedestals in northern New York and Vermont, can help define long-term maximum shaking intensity of earthquakes in the region......»»
NMR spectroscopy method provides faster way to determine chiral structure of molecules
Researchers from Karlsruhe Institute of Technology (KIT) and Voxalytic GmbH have developed a new method that allows, for the first time, the elucidation of the chiral structure of molecules—the exact spatial arrangement of the atoms—by nuclear ma.....»»
Witness 1.8 billion years of tectonic plates dance across Earth"s surface in a new animation
Using information from inside the rocks on Earth's surface, we have reconstructed the plate tectonics of the planet over the last 1.8 billion years......»»
Engineers smash rocks to see what occurs when top layer of an asteroid-like object is hit with extreme external force
Johns Hopkins engineers have uncovered new details about how granular materials such as sand and rock behave under extreme impacts—findings that could someday help protect the Earth from dangerous asteroids......»»
Spectroscopy study reveals electrons in cocatalyst periphery drive photocatalytic hydrogen evolution
Synchronizing periodic excitations of photocatalysts with a Michelson interferometer on operando FT–IR spectroscopy, researchers led by Toshiki Sugimoto succeeded in observing and identifying the reactive electron species for photocatalytic hydroge.....»»
The Onyx Boox Go is one of the coolest tablets I’ve ever used
There are note-taking tablets. Then there's the Boox Go 10.3 by Onyx. This sunlit slate runs Android, rocks an enviable design, and offers a ton of tricks......»»
Researchers develop near-infrared spectroscopy models to analyze corn kernels and biomass
In the agricultural and food industry, determining the chemical composition of raw materials is important for production efficiency, application, and price. Traditional laboratory testing is time-consuming, complicated, and expensive. New research fr.....»»
Darwin"s fear was unjustified: Study suggests fossil record gaps not a major issue
Fossils are used to reconstruct evolutionary history, but not all animals and plants become fossils and many fossils are destroyed before we can find them (e.g., the rocks that contain the fossils are destroyed by erosion). As a result, the fossil re.....»»
New data on radiation show missions to Jupiter"s moon Europa are possible
Scientists from NASA's Juno mission have developed the first complete 3D radiation map of the Jupiter system, including characterizing the intensity of the high-energy particles near the orbit of the icy moon Europa, and how the radiation environment.....»»
Researchers develop nanoparticle array implantation for sensitive and reusable detection
Shanghai Jiao Tong University (SJTU) researchers have developed a highly sensitive and reusable surface-enhanced Raman spectroscopy (SERS) microfluidics system that has achieved a detection limit lower than 10 ppt (parts per trillion) of harmful subs.....»»
Scientists characterize shale cap rocks at tiny scales
