متن کاملIce-Water Phantom Localisation for Diffusion Calibration
When multiple scanners are used to acquire diffusion MR image data from the same patient (even on the same day), there is no guarantee that identical settings will result in comparable images of a specific organ and region. Despite this, for clinical use, any software developed to compute the apparent diffusion coefficient (ADC) must be expected to give equivalent results. What is needed is a p...
متن کاملTunable electrical and thermal transport in ice-templated multilayer graphene nanocomposites through freezing rate control.
We demonstrate tunable electrical and thermal conductivities through freezing rate control in solution-based nanocomposites. For a prototypical suspension of 1 vol % multilayer graphene suspended in hexadecane, the solid-liquid electrical conductivity contrast ratio can be tuned from 1 to 4.5 orders of magnitude for freezing rates between 10(2) and 10(-3) °C/min. We hypothesize that this dramat...
متن کاملThermal Desorption of Water-Ice in the Interstellar Medium
Water (H2O) ice is an important solid constituent of many astrophysical environments. To comprehend the role of such ices in the chemistry and evolution of dense molecular clouds and comets, it is necessary to understand the freeze-out, potential surface reactivity, and desorption mechanisms of such molecular systems. Consequently, there is a real need from within the astronomical modelling com...
متن کاملMeasurement of freezing point depression of water in glass capillaries and the associated ice front shape.
Variations of the Kelvin equation [W. Thomson, Philos. Mag. 42, 448 (1871)] to describe the freezing point depression of water in capillaries exist in the literature. The differing equations, coupled with the uncertainty in input parameters, lead to various predictions. The difference between the predictions may become substantial when the capillary size decreases much below micron dimensions. ...
