Control of ice thickness in cryo-EM via confinement

Liming Zheng, Jiling Song, Xiaole Zhao, 曹家枞 et autres

Achieving thin ice with optimal thickness is a prerequisite for successful cryo-EM analysis of embedded macromolecules. Despite decades of effort, precise control of ice thickness in cryo-EM remains a major challenge. Here, we reveal that the intrinsic instability of sub-100-nm liquid film, …

Energy and Exergy Analysis, and Thermoeconomic Performance of a BCHP System

曹家枞, 刘凤强, 秦志红, 曹双华 et autres

Building cooling, heating and power (BCHP) systems should play an important role in achieving the goals of energy efficient use and environment protection in China. It will make big sense when this type of system shows a good performance energetically and economically. …

THE SECOND LAW ANALYSIS OF GLOBAL IRRADIANCE BASED ON OBSERVED SPECTRAL DISTRIBUTIONS

曹家枞

There have emerged ample literature about the Second Law analysis of extraterrestrial and terrestrial solar radiation consequent to the pioneer works by R. Petela and D. C. Spanner, of which most are irrelevant to the frequency distribution of solar radiation. Since the …
