Melting the ice one layer at a time.
The melting of ice is one of the most common processes on earth. Interestingly, as an ice crystal is warmed from below toward its bulk melting temperature of 0 ◦C a thin film of water forms on it. This water film, referred to as a premelting layer or a quasi-liquid layer (QLL), has been known about for well over a century (1). It is relevant not just to the melting of ice but to important assoc...
متن کاملThermodynamics of RNA melting, one base pair at a time.
The melting of base pairs is a ubiquitous feature of RNA structural transitions, which are widely used to sense and respond to cellular stimuli. A recent study employing solution nuclear magnetic resonance (NMR) imino proton exchange spectroscopy provides a rare base-pair-specific view of duplex melting in the Salmonella FourU RNA thermosensor, which regulates gene expression in response to cha...
متن کاملTackling the Provenance Challenge one layer at a time
VisTrails is a new workflow and provenance management system that provides support for scientific data exploration and visualization. Whereas workflows have been traditionally used to automate repetitive tasks, for applications that are exploratory in nature, change is the norm. VisTrails uses a new change-based provenance mechanism which was designed to handle rapidly-evolving workflows. It un...
متن کاملSimulating ice nucleation, one molecule at a time, with the 'DFT microscope'.
Few physical processes are as ubiquitous as the nucleation of water into ice. However, ice nucleation and, in particular, heterogeneously catalyzed nucleation remains poorly understood at the atomic level. Here, we report an initial series of density functional theory (DFT) calculations aimed at putting our understanding of ice nucleation and water clustering at metallic surfaces on a firmer fo...
متن کاملGrain boundary melting in ice.
We describe an optical scattering study of grain boundary premelting in water ice. Ubiquitous long ranged attractive polarization forces act to suppress grain boundary melting whereas repulsive forces originating in screened Coulomb interactions and classical colligative effects enhance it. The liquid enhancing effects can be manipulated by adding dopant ions to the system. For all measured gra...
