A Multifaceted Kinetic Model for the Thermal Decomposition of Calcium Carbonate

open access: yesCrystals, 2020
The existing kinetic models often consider the influence of a single factor alone on the chemical reaction and this is insufficient to completely describe the decomposition reaction of solids.

Yield stress fluids method to determine the pore size distribution of a porous medium [PDF]

open access: yes, 2014
In this paper a new method is presented in order to determine the pore size distribution in a porous medium. This original technique uses the rheological properties of some non-Newtonian yield stress fluids flowing through the porous sample.

Gas hydrate growth and dissociation in narrow pore networks: capillary inhibition and hysteresis phenomena [PDF]

open access: yes, 2009
Marine sediments hosting gas hydrates are commonly fine-grained (silts, muds, clays) with very narrow mean pore diameters (0.1 mm). This has led to speculation that capillary phenomena could play an important role in controlling hydrate distribution in

A handheld platform for target protein detection and quantification using disposable nanopore strips

open access: yesScientific Reports, 2018
Accessible point-of-care technologies that can provide immunoassay and molecular modalities could dramatically enhance diagnostics, particularly for infectious disease control in low-resource settings. Solid-state nanopores are simple and durable sensors
