Cell imaging systems and methods
Disclosed herein are systems and methods for imaging cells. Quantitative phase imaging uses variations in the index of refraction of a sample as a source of endogenous contrast, providing label-free information of sub-cellular structures and allowing for the reconstruction of valuable biophysical parameters, such as cell dry-mass at femtogram scales, mass transport, and sample thickness and fluctuations at nanometer scales. As a result, QPI has become a valuable tool in biology and medicine.

The disclosed methods and systems can provide for reconstruction of QPI and corresponding analysis for imaging samples of cells in thick samples using an epi-illumination configuration. |

A dual-comb spectrometer comprising two lasers outputting respective frequency combs having a frequency offset between their intermode beat frequencies. One laser acts as a master and the other as a follower. Although the master laser is driven nominally with a DC drive signal, the current on its drive input line nevertheless oscillates with an AC component that follows the beating of the intermode comb lines lasing in the driven master laser.

Adsorptive xenon recovery process from a gas or liquid stream at cryogenic temperature
The present invention relates to an adsorption process for xenon recovery from a cryogenic liquid or gas stream wherein a bed of adsorbent is contacted with a xenon-containing liquid or gas stream selectively adsorbing the xenon from said stream. The adsorption bed is operated to at least near full breakthrough with xenon to enable a deep rejection of other stream components, prior to regeneration using the temperature swing method. After the stripping step, the xenon adsorbent bed is drained to clear out the liquid residue left in the nonselective void space and the xenon molecules in those void spaces is recycled upstream to the ASU distillation column for increasing xenon recovery. The xenon adsorbent bed is optionally purged with oxygen, followed by purging with gaseous argon at cryogenic temperature (≤160 K) to displace the oxygen co-adsorbed on the AgX adsorbent due to higher selectivity of argon over oxygen on the AgX adsorbent. By the end of this step, the xenon adsorbent bed is filled with argon and xenon. Then the entire adsorbent bed is heated indirectly without utilizing any of the purge gas for direct heating. Operating the adsorption bed to near full breakthrough with xenon and displacing the adsorbed oxygen and other residues with argon, prior to regeneration, along with indirect heating of the bed, enables production of a high purity product ≥40 vol % xenon from the adsorption bed and further enables safely heating without any purge gas and ease for downstream product collection, even in cases where hydrocarbons are co-present in the feed stream. |

Method for inhibiting flash point of trans-1,2-dichloroethylene (T-1,2-DCE) and use of T-1,2-DCE
A method for inhibiting a flash point of trans-1,2-dichloroethylene (T-1,2-DCE) and a use of T-1,2-DCE are provided. The T-1,2-DCE has an excellent cleaning effect and is environmental friendly but cannot be used alone because of huge safety hazard caused by its low flash point. 1-chloro-3,3,3-trifluoropropene (HCFO-1233zd) is used to inhibit the flash point of T-1,2-DCE. However, because the actual boiling points of these two substances are quite different, the two substances are easily separated at a slightly-high ambient temperature. Because a boiling point of HCFO-1233zd is extremely low, HCFO-1233zd will escape rapidly, resulting in the loss of inhibition on the flash point. In the present disclosure, T-1,2-DCE and 1-chloro-2,3,3-trifluoropropene are mixed to prepare a mixed solution, and the mixed solution can effectively maintain the inhibition on the flash point of T-1,2-DCE in various ambient temperatures, such that the T-1,2-DCE can be heated to generate a steam for cleaning. |
