Abstract:
Device for detecting a gas, comprising: excitation means, for exciting said gas by means of an electromagnetic wave having a wavelength corresponding approximately to that of said gas; and detection means, for detecting the excitation of said gas, characterized in that it comprises: a waveguide (1) connected to said excitation means, a part (11) of which forms a movable element designed to be in contact with said gas and capable of being set into vibration by the impact of the excited gas molecules; and a measurement sensor (4), for measuring the vibration of said element, said measurement sensor and said element forming said detection means.
Abstract:
A heating mould for thermal nanoimprint lithography, a process of producing the mould, and a process for producing a nanostructured substrate employing the mould. The heating mould includes a substrate having a first principal surface and a second principal surface, and a through-cavity extending from a first orifice in the first principal surface up to a second orifice in the second principal surface. The heating mould also includes a thermally conducting layer that mechanically supports the second membrane, an insulating layer beneath the thermally conducting mechanical support layer, heating means and an electrically and thermally insulating layer which covers the heating means and, at least partially, the second membrane, imprint patterns on the electrically and thermally insulating layer, and means for supplying an electric current to the heating means.
