Depositional ice nucleation on solid ammonium sulfate and glutaric acid particles [PDF]
Atmospheric Chemistry and Physics, 2010 Heterogeneous ice nucleation on solid ammonium sulfate and glutaric acid particles was studied using optical microscopy and Raman spectroscopy. Optical microscopy was used to detect selective nucleation events as water vapor was slowly introduced into an

Ice nucleation abilities of soot particles determined with the Horizontal Ice Nucleation Chamber [PDF]
Atmospheric Chemistry and Physics, 2018 Ice nucleation by different types of soot particles is systematically investigated over the temperature range from 218 to 253 K relevant for both mixed-phase (MPCs) and cirrus clouds.

Advanced Materials, EarlyView.Precursor carbon stoichiometry programs internal strain and oxygen substitution in Ti3AlCxO2‐x, deterministically switching Ti3CxO2‐xTz MXenes between highly aligned 2D nanosheets and spontaneous 1D nanoscrolls. This synthesis‐stage architecture control enables ultrathin X/W‐band EMI shielding with outstanding mass‐normalized performance and bending ...

Sensitivity studies of dust ice nuclei effect on cirrus clouds with the Community Atmosphere Model CAM5 [PDF]
Atmospheric Chemistry and Physics, 2012 In this study the effect of dust aerosol on upper tropospheric cirrus clouds through heterogeneous ice nucleation is investigated in the Community Atmospheric Model version 5 (CAM5) with two ice nucleation parameterizations.

Matrix Viscoelasticity Regulates Dendritic Cell Migration and Immune Priming
Advanced Materials, EarlyView.Matrix viscoelasticity is a key mechanical feature of the tumor microenvironment but remains poorly understood in immune regulation. Here, we develop a tunable collagen platform to decouple viscoelasticity from stiffness and show that slow‐relaxing matrices constrain dendritic cell migration by limiting actomyosin‐driven matrix remodeling, thereby ...

Surface-induced water crystallisation driven by precursors formed in negative pressure regions
Nature CommunicationsIce nucleation is a crucial process in nature and industries; however, the role of the free surface of water in this process remains unclear. To address this, we investigate the microscopic freezing process using brute-force molecular dynamics ...

Enhanced heterogeneous ice nucleation by special surface geometry
Nature Communications, 2017 Understanding ice nucleation is important for the development of accurate cloud models. Here Biet al. show that sharp wedges can enhance ice nucleation both when the wedge geometry matches the ice lattice and when such matching is absent, in which case ...
