Scientists probe the limits of ice(图)     Scientists  probe  limits of ice       font style='font-size:12px;'> 2019/11/15
How small is the tiniest possible particle of ice? According to new NSF-funded research published in the journal Proceedings of the National Academy of Sciences, the smallest nanodroplet of water in w...
Cosmos Code Helps Probe Space Oddities(图)     Cosmos Code  Probe Space       font style='font-size:12px;'> 2017/11/23
Black holes make for a great space mystery. They're so massive that nothing, not even light, can escape a black hole once it gets close enough. A great mystery for scientists is that there's evidence ...
Two Johns Hopkins materials science graduate students and their professors played a key role in a multi-institution research project that pinpointed how a tiny protein seems to make the deadly Ebola v...
The role of electric fields in important biological processes such as binding and catalysis has been studied almost exclusively by computational methods. Experimental measurements of the local electri...
The nitrile stretching mode of the thiocyanate moiety is a nearly ideal probe for measuring the local electric field arising from the organized environment of the interior of a protein. Nitriles were ...
We report the first measurement of the vibrational Stark effect in a protein, providing quantitative information on the sensitivity of a vibrational transition to an applied electric field. This can b...
We will outline an experimental approach that uses large magnetic fields and simple optical methods, combined with a method of data analysis, that is ideally suited for studying the mechanism of rapid...
We propose a feasible experimental scheme to realize a three-dimensional chiral topological insulator with cold fermionic atoms in an optical lattice, which is characterized by an integer topological ...
Direct Probe of Topological Order for Cold Atoms.     Direct Probe  Topological Order  Cold Atoms       font style='font-size:12px;'> 2016/1/22
Cold-atom experiments in optical lattices offer a versatile platform to realize various topological quantum phases. A key challenge in those experiments is to unambiguously probe the topological order...
The burgeoning field of optogenetics makes it possible for scientists to control brain activity using pulses of light. Now, Brown University researchers have developed an optogenetic device which open...
Ground-based radio observations to probe the ozone content in the meteor region     meteor  radar  ozone       font style='font-size:12px;'> 2015/9/16
Radar studies of the plasma irregularities produced by meteoroid ablation provide a powerful diagnostic probe of the Earth's atmosphere. This role is especially important as an inexpensive route for s...
This paper discusses the performance of electrical spectroscopy using a RESPER probe to measure the salinity s and volumetric content θW of the water in concrete or terrestrial soil. The RESPER probe ...
Basalt lavas comprise the greatest volume of volcanic rocks on Earth, and most of them erupt along the world's mid-ocean ridges (MORs). These MOR basalts (MORBs) are generally thought to be relatively...
Astronomers Probe Young Star and its Planets(图)     Astronomers  Young Star  Planets       font style='font-size:12px;'> 2015/4/29
Taking advantage of the unprecedented sensitivity of the Large Binocular Telescope in southeastern Arizona, an international team of astronomers has obtained the first results from the LEECH exoplanet...
Permeability is one of the most important petrophysical parameters to describe the reservoir properties of sedimentary rocks, pertaining to problems in hydrology, geothermics, and hydrocarbon reservoi...
