# New article: Intumescence in waterglass

Waterglass exhibits intumescent behavior on thermal treatment, a property being utilized extensively for fire-resistant glass applications. Here, we report on the fundamental understanding of the macro and microscopic structural changes related to foaming.

# New article: Fluctuation dynamics modified by intermolecular forces.

Van der Waals forces modify the fluctuations of the surface of a liquid film and this effect has been measured in collaboration between SVI, SIMM (ESPCI, Paris) and LOMA (Univ. Bordeaux)

# New article: Smart liquid crystal defects

Micrometric, electrically irreversible smectic A liquid crystal defect patterns can be used as active films for smart windows with voltage-adjustable and reversible haze levels.

# New article: Granular jet in water

Falling jet of dry granular material in water: We show the role of the capillarity and velocity in designing the shape of the interface between the dry grains and the wet material.

# New article: When the glass reveals its thermal history

A casted glass flow keeps the memory of its local cooling rate, as revealed by precise Raman spectroscopy.
