Thermoporosimetry
Thermoporometry and cryoporometry are methods for measuring porosity and pore-size distributions. A small region of solid melts at a lower temperature than the bulk solid, as given by the Gibbs–Thomson equation. Thus, if a liquid is imbibed into a porous material, and then frozen, the melting temperature will … Visa mer DSC Thermoporometry This technique uses differential scanning calorimetry (DSC) to detect the phase changes. The signal detection relies on transient heat flows of latent heat of fusion at the phase … Visa mer The Gibbs–Thomson effect acts to lower both melting and freezing point, and also to raise boiling point. However, simple cooling of an all-liquid sample usually leads to a state of … Visa mer • cryoporometry.com • nano-science.co.uk/nano-metrology/ Visa mer NMR cryoporometry (external cryoporometry website) is a very useful nano- through meso- to micro-metrology technique (nanometrology, nano-science.co.uk/nano-metrology) that has been used to study many materials, and has particularly been … Visa mer Webb28 maj 2024 · A measurement method of the apparent particle density of the carbon nanotube (CNT) particles, characterized by enveloped volume formed by loosely entangled nanotubes, has been proposed for the CNT fluidized bed application.
