Les sulfates pour des matériaux énergétiques "verts"

26-02-2015

Angewandte Chemie, la revue internationale la plus prestigieuse dans le domaine de la chimie expérimentale, vient de publier en ligne un article intitulé « Sulfates-based nanothermites: an expanding horizon for metastable interstitial composites » issu des recherches réalisées par le Docteur Marc COMET et l’équipe du laboratoire NS3E sur l’usage de sulfates comme substances comburantes dans les nanothermites.

Les sulfates sont des substances très communes que nous rencontrons ou utilisons fréquemment dans notre vie quotidienne. Le sulfate de sodium est le constituant de base de la plupart des lessives en poudre. Le sulfate de magnésium possède de nombreuses indications médicales en tant que source de magnésium. Le sulfate de calcium, plus connu sous le nom de plâtre, compose ou revêt la plupart des cloisons intérieures de nos habitations. Le principe actif de la « bouillie bordelaise », produit phytosanitaire utilisé comme fongicide et antibactérien horticole, est le sulfate de cuivre. La pierre d’alun utilisée comme déodorant est un sulfate double de potassium et d’aluminium. L’électrolyte garnissant les batteries de nos automobiles est l’acide sulfurique, qui corrode parfois les cosses (sulfatage) avec formation de sulfate de plomb. Le sulfate d’aluminium est utilisé pour comme agent de floculation des colloïdes dans les procédés...

A new continuous processing technology used to produce medical nanodrugs

28-10-2014

 

Recently, researchers belonging to the Research Unit focussing on Nanomaterials for Systems under Extreme Stress (NS3E) run jointly by the French-German Research Institute of Saint-Louis and the French National Centre for Scientific Research (CNRS) as well as the University of Strasbourg developed a new continuous processing technology used for an industrial-scale production of organic or organometallic nano co-crystals with perfectly controlled size and composition. This method is protected by three patents at international level and is a decisive step towards mass production of medical nanodrugs, energetic nanomaterials as well as organic and organometallic nano-scale materials. The results were published in the journal Scientific Reports.

The production of organic or organometallic nanoparticles with specific size and composition is a real challenge in different fields of activity, such as pharmaceutics, optics, ferroelectric crystals and energetic materials (propellants or explosives). The main advantage of using these compounds is, for example, the production of multifunctional drugs containing one or more co-crystallized active ingredients with co-crystal structure being able to increase their kinetics (speed) of assimilation in the human body. In view of using co-crystals in many drugs, the continuous processing of drugs has been a real challenge up to now...

The French-German Research Institute of Saint-Louis is a binational research institute established by the Federal Republic of Germany and the French Republic on the basis of a treaty signed in 1958. The core mission of ISL is: "Research, scientific studies and basic predevelopment in the field of defense and security.

The classical working areas of ISL include: laser-matter interaction, laser development, detonics, perforation, protection, ballistics, the environment and protection of the soldier, acoustics, power electronics, high-power microwaves, aerodynamics and flight mechanics, optronics, sensors.

ISL has reinforced its activities on issues of civil security and countermeasures against terrorism encountered both at home and during overseas military operations.

The institute is situated in Southern Alsace near the German and Swiss borders.
