The present invention relates to a method for producing a microfluidic device, in particular, a sol-gel method for producing a microfluidic device in hybrid silica glass. The invention also relates to a microfluidic device obtainable by the method as described above and to microfluidic device in hybrid silica glass comprising at least one microchannel having a depth of at least 1 &#x3bc;m, preferably between 1 &#x3bc;m and 1 mm, and more preferably between 10 and 100 &#x3bc;m.

Method for producing a microfluidic device

The present invention relates to a method for preparing nanoparticles at least partially consisting of rare earth fluoride, characterized in that said fluoride is produced, in a solution, from a salt of the corresponding rare earth element and from a charge-transfer complex of formula (I), where Ra, Rb, and Rc are as defined in claim

Method for preparing rare earth fluoride nanoparticles

The invention concerns a preparation process of a hybrid organic-inorganic material including the following successive steps:

Hybrid organic-inorganic material constituted by a silica network having photochromic agents and optical power limiting agents as a doping agent in the material

The object of the invention is new complexes of derivatives of thiacalix[4]arenes having the formula:R, R, R, R, R, R, Ret Rare such as defined in claim 1 and their utilization, especially for manufacturing of materials having optical limiter properties.
