Conference prices

SPS Scientific Comitee proposed deux scientific prices:

• "Best Student poster price".

The winner has be selected during Thursday poster session. It is Anna Novikova.Some words to present her work hereafter :

Needs in infrared optics are rising with needs in infrared cameras. Chalcogenide glasses are right candidates for the manufacturing of infrared lenses with good resolution at low cost. Since they are sensitive to oxygen, they are synthetized under vacuum in a sealed silica tube. Non reusable and expensive, the silica represents 30% of the production cost. To overcome these limitations, a new process has been developed which combines ball milling and SPS sintering. Ball-milling allows the production of large panel of glass compositions without any use of silica. The mechanical energy brought to the starting elements (like Ge, Ga, Se, Sb…) induces the chemical reaction and the glass formation. The obtained powder is sintered by SPS. By this process, lenses with the right geometry and low roughness have been obtained.

• "Price of the best micrograph for SPS 2017 Conference".

Zofia Trzaska, is currently an associate professor at the Industrial Engineering and Maintenance Dept. of the Technology Institute at University Paris 13. After studying SPS densification mechanisms during her PhD, she is now investigating the effects of thermomechanical treatments on mechanical behavior of titanium alloys processed by SPS. She is especially interested in plasticity mechanisms in structural materials, using mainly transmission electron microscopy (TEM).
