Solids formation can substanitally reduce the energy penalty for ammonia solvent regeneration in carbon capture and storage (CCS), but has been demonstrated literature to be difficult control. This study examines use of hollow fibre membrane contactors, as this indirect contact mediated between liquid gas phases geometry could improve regulation solids formation. Under conditions comparable exi...

A model to simulate the time evolution of the distribution of agglomeration degree of sucrose crystals is deduced and validated against experimental data obtained through an image analysis technique. The crystallisation laboratory facility, procedures and the resulting experimental data are described. The model employed includes nucleation, growth, growth rate dispersion and agglomeration kinet...

Motivated by potential applications in architecture, we study Darboux cyclides. These algebraic surfaces of order ≤ 4 are a superset of Dupin cyclides and quadrics, and they carry up to six real families of circles. Revisiting the classical approach to these surfaces based on the spherical model of 3D Möbius geometry, we provide computational tools for the identificiation of circle families on ...

Nanonucleants for protein crystallisation in the presence of impurities.

The efficiency of a cosmetic product depends not only on the active ingredients, but also on the carrier system devoted to improve its bioavailability. This article aims to encapsulate two couples of UV molecular absorbers, with a blocking action on both UV-A and UV-B domains, into efficient lipid nanoparticles. The effect of encapsulation on the specific properties such as sun protection facto...

In this short note we propose a new method for construction new nice arrangement on the sphere Sd using the spaces of spherical harmonic.

We show how crystallisation of supramolecular isomers of a dynamic coordination system generates a series of isostructural porous materials. These mercury, cobalt and zinc metallocyclic materials show permanent porosity and exhibit single-crystal-to-single-crystal transformations.
