TL;DR: It is concluded that the model of concentration addition may be useful to estimate the EC50 values of ionic liquids that have not been tested or even synthesised yet, and seems to be the key structural features leading to the observed anion cytotoxicity.

TL;DR: Increased negative surface charge correlates strongly with increased protein solubility and may be due to strong binding of water by the acidic amino acids, and the results obtained for the two different precipitants agree closely with each other, suggesting that the two precipitant probe similar properties that are relevant to solubilty in buffer alone.

TL;DR: In this paper, the authors analyzed deep-sea cores from the central Arctic Ocean, the Fram Strait, and the Yermak Plateau to reconstruct the history of marine paleoenvironment and terrestrial glaciation in the last 200,000 years.

TL;DR: The observation of a doublet structure in the low-temperature photoluminescence of interlayer excitons in heterostructure consisting of monolayer MoSe2 and WSe2 provides fundamental insights into long-lived interlayer states in van der Waals heterostructures with possible bosonic many-body interactions.
Abstract: We report the observation of a doublet structure in the low-temperature photoluminescence of interlayer excitons in heterostructures consisting of monolayer MoSe2 and WSe2. Both peaks exhibit long photoluminescence lifetimes of several tens of nanoseconds up to 100 ns verifying the interlayer nature of the excitons. The energy and line width of both peaks show unusual temperature and power dependences. While the low-energy peak dominates the spectra at low power and low temperatures, the high-energy peak dominates for high power and temperature. We explain the findings by two kinds of interlayer excitons being either indirect or quasi-direct in reciprocal space. Our results provide fundamental insights into long-lived interlayer states in van der Waals heterostructures with possible bosonic many-body interactions.
