Immediate evacuation order by emergency exits. This is not an exercise. Retreat with calm and discipline.
Gentlemen, it's been an honour and a privilege to be your captain over these years. Good luck to all of you.

... and remember I expect your results and reports twice a week. There are things bigger and nastier than a virus that still exist...
Organic chemistry is gaining an increasing interest in the optics lab these days. According to WHO, here is a simple hanrub sanitizer recipe:
For a 1L solution, mix 833mL ethanol 96%, 4.2mL hydrogen peroxide 30%, 1.5mL glycerol and 161mL pure water. Shake well, avoid eye contact and do not even think of drinking it.
Even viruses have nightmares. So wash your hands and get results before he finds you...
Adhesion layers of chromium or titanium are widely used in plasmonics to ensure a proper adhesion between a gold film and a glass substrate. However, very little is known about their influence on the thermal response. As a result, the adhesion layer is often ignored while designing the experiments.
In a recent article published in Nanoscale, we demonstrate both experimentally and numerically that the adhesion layer can have a major impact on the thermal response of plasmonic structures.
- We quantify the role of the adhesion layer in setting the local temperature around a single nanostructure milled in a gold film.
- We show how to promote or avoid the temperature increase using different experimental designs. This further expands the plasmonic toolbox for heat-controlled experiments.

Many concepts of physical optics can be visually illustrated on a relatively simple optical setup in a table-top format, not requiring any very specific equipment. Diffraction, interferences, speckle, image formation, Fourier optics, strioscopy are among the many themes to be shown using this demonstration system.
Is there light in the center of a shadow from a black disk? What is the shadow of a hole milled in an opaque screen? Can adding light to light create darkness?
The Institut Fresnel releases a series of short videos answering various questions about light and optics, providing an illustration of physical optics concepts such as diffraction, interferences, imaging and microscopy.
See our official trailer below (sounds very pro like that). More videos on the Institut Fresnel youtube channel.
