Light and Heat Create New Biocompatible Microparticles
Using light and heat, researchers at Duke University developed a technique for manufacturing biocompatible microparticles for potential use in drug delivery, diagnostics, and tissue engineering. According to research scientist Stefan Roberts, the technique is simple enough to be scaled up to make billions of microparticles in just a few minutes.

III-V Lasers Grown on Silicon Wafers Could Advance Silicon Photonics
Researchers from the Hong Kong University of Science and Technology have directly grown 1.5-µm III-V lasers on industry-standard 220-nm silicon-on-insulators (SOI) wafers without buffer. This work could advance the use of III-V light sources with silicon (Si)-based photonic devices.

Lasers Could Lead Search for Water on Earth’s Moon
There are craters in the moon’s south pole that have remained dark for billions of years, but scientists have found evidence that the region may contain water. NASA has awarded nearly $1 million to eight university teams to develop methods to search for, and eventually extract, water from these permanently shadowed regions.

Butterfly Wing Nanostructures Achieve Ultrablack in Ultrathin Structures
A team at Duke University is studying butterflies with wings that are 10 to 100 times darker than everyday black objects. As little as 0.06% of the light that hits the ultrablack butterfly wings is reflected back to the eye. This percentage is close to the blackest black coatings made by humans to help solar panels absorb more energy or enable line telescopes to reduce stray light.

Getting Specific About Coating Specifications
Wed, Apr 15, 2020 1:00 PM - 2:00 PM EDT
In this webinar, the technical team at North American Coating Laboratories (NACL) will provide a basis for specifying, testing, and confirming that your coating needs are clearly stated on drawings and are clearly conveyed to your coating solutions provider. To achieve this, the NACL team asks that you let them know what challenges you have faced or are facing currently with regard to specifying and testing optical coatings and meeting your coating requirements. You can do this when you complete the registration process. The NACL team will review all responses and prepare a presentation that is customized to the concerns of the registrants.
