Phase Transitions: Sublimation and Deposition
0 Views •
2020
Some solids can transition directly into the gaseous state, bypassing the liquid state, via a process known as sublimation. At room temperature and standard pressure, a piece of dry ice (solid CO2) sublimes, appearing to gradually disappear without ever forming any liquid. Snow and ice sublimate at temperatures below the melting point of water, a slow process that may be accelerated by winds and the reduced atmospheric pressures at high altitudes. When solid iodine is warmed, the solid sublimes...

The creation of functional microtissues within microfluidic devices requires the stabilization of cell phenotypes by adapting traditional cell culture techniques to the limited spatial dimensions in microdevices. Modification of collagen allows the layer-by-layer deposition of ultrathin collagen assemblies that can stabilize primary cells, such as hepatocytes, as microfluidic tissue models.

Molecular imaging with matrix-assisted laser desorption/ionization-based imaging mass spectrometry (MALDI-IMS) allows the simultaneous mapping of multiple analytes in biological samples. Here, we present a protocol for the detection and visualization of amyloid β protein on brain tissues of Alzheimer's disease and cerebral amyloid angiopathy samples using MALDI-IMS.

We present the synthesis of the organic-based ferrimagnet vanadium tetracyanoethylene (V[TCNE]x, x~2) via low temperature chemical vapor deposition (CVD). This optimized recipe yields an increase in Curie temperature from 400 K to over 600 K and a dramatic improvement in magnetic resonance properties.
FAQs
Particle size, surface chemistry, flow conditions, and matrix composition jointly control where material accumulates and how strongly it remains retained. Smaller or chemically interactive particles may behave differently from larger or less reactive ones, while changing flow can alter settling and redistribution. Considering these variables helps explain spatial differences in environmental accumulation.
Different pathways produce different retention patterns. Settling moves suspended particles downward, adsorption attaches dissolved substances to surfaces, precipitation forms deposited material, filtration removes particles as matrix structure restricts movement, and biological production adds material generated within the system. Distinguishing these pathways helps researchers interpret whether accumulated substances are transported, retained, or produced locally.
Flow conditions influence whether particles and dissolved substances remain suspended, settle, or become redistributed. Changes in movement through or across a matrix can therefore alter both deposition rates and the location of accumulated material. Accounting for flow helps environmental researchers distinguish stable retention from temporary accumulation caused by transport conditions.
An assessment should relate deposition rates to the material being accumulated, the surrounding matrix, and the conditions that govern movement and retention. Researchers can examine whether the material is a nutrient, contaminant, or biological product, then consider particle size, surface chemistry, flow, and matrix composition. This approach supports interpretation of accumulation and redistribution.
Tracking where contaminants accumulate and how deposition rates change helps clarify their environmental fate. In sediment studies, the observations can contribute to assessments of sediment quality by showing how materials become retained or redistributed. These findings also help characterize potential ecosystem exposure and provide context for evaluating environmental conditions.
Matrix deposition measurements can support remediation evaluations by showing whether targeted materials remain retained, become redistributed, or continue accumulating after an intervention. Comparing deposition patterns and rates across relevant matrices provides evidence about changes in pollutant movement and retention. The results can therefore help determine whether remediation is affecting environmental exposure and contaminant fate.
