TL;DR: In this paper, a process for treating cellulosic fibres which process comprises pre-treating the fibres with an enzyme in a first enzymatic treatment followed by mechanical pre-treatment in the first mechanical treatment and then a second mechanical treatment in the second one to form microfibrillated cellulose.

Determination of the glass transition temperature of latex films: Comparison of various methods
TL;DR: In this paper, the glass transition temperature (T g ) for two latices with different styrene/butadiene compositions was determined by the thermal SPM probe resonance frequency method, which was compared with the T g values obtained by differential scanning calorimetry (DSC), dynamical mechanical analysis (DMA), process rheometer (PR) and thermo-mechanical analyzer (TMA) measurements.

TL;DR: In this paper, a process for the production of microfibrillated cellulose is described, in which the process comprises the steps of, providing a slurry comprising fibers, adding the slurry to an extruder, treating the slurghurry in the extruder so that the fibers are defibrilled, and then forming a micro-fibrilled cellulose.

Flocculation of calcite dispersions induced by the adsorption of highly cationic starch
TL;DR: In this paper, the interaction between highly cationic starch and calcite was investigated by determining the adsorption isotherms and the flocculation of the calcite dispersions at different concentrations of starch.

Impact spreading and absorption of Newtonian droplets on topographically irregular porous materials
TL;DR: In this article, a volume of fluid method is used to simulate the motion of up to 50 μ m diameter droplets onto surfaces comprising protuberances below 12 μ m in width, and surface geometry is shown to be a critical determinant of both spreading and absorption.
