1. Interlaboratory study of the operational stability of automated sorption balances 

   Zelinka, Samuel L.; Glass, Samuel V.; Lazarcik, Eleanor Q. D.; et al. (2024)

   Adsorption

   Automated sorption balances are widely used for characterizing the interaction of water vapor with hygroscopic materials. These instruments provide an efficient way to collect sorption isotherm data and kinetic data. A typical method for defining equilibrium after a step change in relative humidity (RH) is using a particular threshold value for the rate of change in mass with time. Recent studies indicate that commonly used threshold ...

2. Examining Atmospheric River Life Cycles in East Antarctica 

   Wille, Jonathan D.; Pohl, Benjamin; Favier, Vincent; et al. (2024)

   Journal of Geophysical Research: Atmospheres

   During atmospheric river (AR) landfalls on the Antarctic ice sheet, the high waviness of the circumpolar polar jet stream allows for subtropical air masses to be advected toward the Antarctic coastline. These rare but high-impact AR events are highly consequential for the Antarctic mass balance; yet little is known about the various atmospheric dynamical components determining their life cycle. By using an AR detection algorithm to retrieve ...

3. Biosynthetic and catabolic pathways control amino acid δ<SUP>2</SUP>H values in aerobic heterotrophs 

   Silverman, Shaelyn N.; Wijker, Reto S.; Sessions, Alex L. (2024)

   FRONTIERS IN MICROBIOLOGY

   The hydrogen isotope ratios (delta H-2(AA) values) of amino acids in all organisms are substantially fractionated relative to growth water. In addition, they exhibit large variations within microbial biomass, animals, and human tissues, hinting at rich biochemical information encoded in such signals. In lipids, such delta H-2 variations are thought to primarily reflect NADPH metabolism. Analogous biochemical controls for amino acids remain ...

4. Substantial cooling effect from aerosol-induced increase in tropical marine cloud cover 

   Chen, Ying; Haywood, Jim; Wang, Yu; et al. (2024)

   Nature Geoscience

   With global warming currently standing at approximately +1.2 degrees C since pre-industrial times, climate change is a pressing global issue. Marine cloud brightening is one proposed method to tackle warming through injecting aerosols into marine clouds to enhance their reflectivity and thereby planetary albedo. However, because it is unclear how aerosols influence clouds, especially cloud cover, both climate projections and the effectiveness ...

5. A Comparison between Predictions of the Miller-Macosko Theory, Estimates from Molecular Dynamics Simulations, and Long-Standing Experimental Data of the Shear Modulus of End-Linked Polymer Networks 

   Tsimouri, Ioanna Ch.; Schwarz, Fabian; Bernhard, Tim; et al. (2024)

   Macromolecules

   Long-standing experimental data on the elastic modulus of end-linked poly(dimethylsiloxane) (PDMS) networks are employed to corroborate the validity of the Miller-Macosko theory (MMT). The validity of MMT is also confirmed by molecular dynamics (MD) simulations that mimic the experimentally realized networks. It becomes apparent that for a network formed from bulk, where the fractions of the loops are small, it is sufficient to account ...
