👀 Who's ready for the #NobelPrize announcements next week...? Physics, Chemistry, Physiology/Medicine, we're ready to celebrate some of the biggest achievements in these fields. Any ideas on hot topics for this year's prizes? Take a look at recipients in the Optica community 👉 bit.ly/4nYjIdP

Oh, this? It's the Opticat mug, now in magenta: https://bit.ly/472nwFc #InternationalCoffeeDay

Evaporation comes from many sources, like a steaming cup of coffee, or even without heat: https://bit.ly/46iIZrQ A study found that visible light evaporates water faster than heat alone, with photons cleaving water molecules off a hydrogel’s surface. #InternationalCoffeeDay💡

In one year, Optica Conferences and Congresses will serve more than 2,000 gallons/7,570 liters of coffee to event attendees! We just issued the 2026 calendar of events. Download your copy and make plans to attend. (Strong cups of coffee will be ready for you.) 😉 👉 https://bit.ly/4nZ60rk

If you're drinking a cup of coffee on #InternationalCoffeeDay, you may notice the coffee-ring effect.💡 When a turbid drop dries on a solid surface, its suspended particulates will be deposited in a ring-like pattern, a phenomenon that may improve site-specific delivery drugs: https://bit.ly/48ax3Lw

Perovskite solar cells need caffeine too...not to get energized, but as a way to slow down the crystallization of perovskite film. By doing so, they can arrange into a more favorable orientation for photovoltaic performance: https://bit.ly/48ai2tk #InternationalCoffeeDay 💡 ⚛️

Do you smell that? 😌 ☕ It's coffee. The coffee we serve at Optica meetings, coffee as a subject of research, coffee in your coffee, and, we hope, coffee in an Opticat mug. Happy #InternationalCoffeeDay, where we're celebrating how a little caffeine goes a long way: https://bit.ly/4gUUZFe 💡

Stretchable waveguides maintain stable transmission even when bent or twisted: https://bit.ly/3IOt3WH A new design helically winds deformable metallic wires onto thermoplastic polyurethane to create flexible waveguides, achieving both elastic recovery and compatibility with fabric and skin. 💡 ⚛️
