Encapsulation of Active Pharmaceutical Ingredient by Double Emulsion to Control Drug Release for Pulmonary Application
This application note deals with the encapsulation of an active pharmaceutical ingredient (API) in a biocompatible matrix to protect it and to control its release in time. We show that a right control of the formulation parameters allows to adapt the size and the porosity of the particles, the two mains characteristics which control and regulate the drug release kinetic. Double emulsion technology is used by GREEnMat to design these particles and to tailor their properties (size, porosity and percentage of the encapsulation).
From Suspension to Powder Using the Spray-Drying Process to Produce Kilograms of Powder as Anode Material for Li-ion Battery
The preparation of muticationic batteries materials as Li4Ti5O12 powder requires high homogeneity in the precursors to produce the powder with desired phase characterized with high electrochemical performances. This can be easily achieved with the spray-drying technology from nanoprecursor suspension. Using this fast process in a one step, we are able to produce at GREEnMat several kilograms of the desired material.
Hydrothermal Synthesis of Advanced and Controlled Powders
Hydrothermal processing is a non-conventional, one-step method to prepare crystalline inorganic materials with good morphological and surface control. It is a simple and effective way to reduce particle size and a suitable method for the morphological and surface control in one step. It consists in the precipitation reaction of chemicals in aqueous solution at moderate temperature and pressure, and is therefore very attractive for the preparation of particles in an environmentally friendly way. Phase formation in hydrothermal conditions often proceeds through one or several intermediates.
