Decline in CO2 cooled Earth’s climate over 30 million years ago
earth's climate CO2 greenhouse
2021/8/5
New research demonstrates that a decline in the concentration of atmospheric CO2 played a major role in driving Earth's climate from a warm greenhouse into a cold icehouse world around 34 million year...
Evidence for the solar wind in lunar magmas: A study of slowly cooled samples of the Apollo 12 olivine basalt suite
hydrogen isotopes melt inclusions mare basalts SIMS lunar olivine
2017/4/10
While it is now recognized that the Moon has indigenous water and volatiles, their total abundances are unclear, with
current literature estimates ranging from nearly absent to Earth-like levels. Sim...
Observation of a rotational transition in trapped and sympathetically cooled molecular ions
Observation rotational transition trapped sympathetically cooled molecular ions
2012/2/28
We demonstrate rotational excitation of molecular ions that are sympathetically cooled by laser-cooled atomic ions to a temperature as low as ca. 10 mK. The molecular hydrogen ions HD+ and the fundame...

Interferometric thermometry single sub-Doppler cooled atom
2012/2/28
Efficient self-interference of single-photons emitted by a sideband-cooled Barium ion is demonstrated. First, the technical tools for performing efficient coupling to the quadrupolar transition of a s...
Remote frequency measurement of the 1S0-3P1 transition in laser cooled 24Mg
Remote frequency measurement 1S0-3P1 transition laser cooled 24Mg Quantum Gases
2011/8/4
Abstract: We perform Ramsey-Borde spectroscopy on laser cooled magnesium atoms in free fall to measure the 1S0-3P1 intercombination transition frequency. The measured value of 655 659 923 839 730 (48)...

2010/8/13
Solid state vapour pressures of a selection of atmospherically important substituted dicarboxylic acids have been measured using Knudsen Effusion Mass Spectrometry (KEMS) over a range of 20 K (298–318...
Numerical computation of the eigenstructure of cylindrical acoustic waveguides with heated (or cooled) walls
acoustic waveguides temperature gradient
2010/9/13
A perturbation procedure for the modes and cut-off frequencies of cylindrical acoustic waveguides of arbitrary cross-section with a small temperature gradient along the walls was presented in [1, 2]. ...
