The Role of Nuclear Quantum Effects in Supercooled Water and Amorphous Ice
<p>Water is one of the most important substances on Earth and plays a fundamental role in numerous scientific and engineering applications. Interestingly, water behaves much differently than other liquids. For example, water shows an anomalous density maximum at 277 K, the solid phase (ice) is less …

Study of slow dynamics in supercooled water by molecular dynamics and quasi-elastic neutron scattering
The slow dynamics of supercooled water is studied by modelling the spectrum of test particle fluctuations: intermediate scattering function (ISF). The theoretical models are compared with experimental measurements by quasi-elastic neutron scattering (QENS) and molecular dynamics (MD) simulation …

A physical model to estimate snowfall over land using microwave measurements
… at high frequencies (nu > 100 GHz) where water vapor screens the surface emission, and sensitivity to frozen hydrometeors is significant. However, the scattering effect of snowfall in the atmosphere at those higher frequencies is also impacted by water vapor and supercooled water in the …

Structure and statistical analysis of the microphysical properties of the comma-head region of cold-season midlatitude cyclones
… cells compared to outside, and derived ice water contents and median mass dimensions averaged 2.2 and 1.1 times larger in cells. Supercooled water was directly measured at temperatures between 31.4 and 11.1°C, with the median and 95th percentile liquid water content increasing from ~0.09 to …

Studies of liquid-liquid phase transition and critical phenomena in supercooled confined water by neutron scattering
… (SANS) is used to measure the density of water contained in 1-D cylindrical pores of a mesoporous silica material MCM-41-S. By being able to suppress the homogenous nucleation process inside the narrow pore, one can keep water in the liquid state down to at least 160 K. We observe a …

Dynamics of biopolymers and their hydration water studied by neutron and X-ray scattering
… to their dynamics. Moreover, protein hydration water is believed to have significant influence on the dynamics of proteins. One of the evidence is that both protein and its hydration water have the same dynamic transition temperature at around 220 K. This thesis intends to understand the dynamic …

Quantitative Trait Loci Analysis of Low Temperature Responses in Grapevine F2 Population
… months and dormant seasons. LTE results when the supercooled water inside the bud freezes and identifies the temperature at which buds are killed. Best linear unbiased predictors (BLUP) was also calculated using the LTEs to calculate random genetic effects. Composite interval mapping (CIM) was …

Effect of environmental temperature on Antarctic fish antifreeze protein activity and concentration
… Peninsula (WAP) experience freezing sea surface water temperatures and ice formation only during the austral winter but the water below 100 m is warmer due to the effects of the Circumpolar Deep Water (CDW) that flows onto the shelf. During the winter the temperature gradient can range from …
