Light-Activated Control of Gene Expression
Using a technique called light-activated dynamic looping, or LADL, scientists at the University of Pennsylvania are investigating the role that genome folding plays in gene expression. The team has demonstrated how LADL can be used for quickly creating specific genome folding patterns on demand, using light as a trigger.

Researchers Confirm Strong Magneto-Optical Resonance in Graphene
Researchers from the University of Geneva (UNIGE) and the University of Manchester have demonstrated an efficient way to control IR and THz waves using graphene, in a study that confirms a 2006 theory predicting that graphene could be used in a magnetic field to absorb THz and IR light on demand and control the direction of the circular polarization.

Canon Surface Reflectance Analyzer
Canon U.S.A. Inc., Industrial Products Div.
Canon RA-532H, Surface Reflectance Analyzer (goniophotometer), is a compact, portable device capable of measuring 4 surface appearance conditions in a single pass: Gloss, Haze, Image Clarity (IC), and BRDF (Bidirectional Reflectance Distribution Function). Additionally, Canon has released its own new parameter, “Scattering” parameter, overcoming the shortage of both IC and DOI (Distinctiveness of Image) when evaluating matte and textured surfaces as well as orange peel surface.

Flexible Sputtered Coatings
Deposition Sciences Inc. (DSI)
Roll-to-roll processes present a number of challenges when coating flexible surfaces, including unbalanced stress on each side of the substrate and limited line speed. These limitations affect the thickness and possibility of complex coatings. To address these challenges, DSI developed their batch coating technology, MicroDyn®. This unique process utilizes a proprietary magnetron sputtering chamber that was custom designed to address the challenges of high throughput coating.

Single-Layer OLED Design Could Lead to Printed Displays
An efficient, stable OLED based on a single layer of a neat, thermally activated, delayed fluorescence emitter has been demonstrated by a research group at the Max Planck Institute for Polymer Research (MPI-P). The first prototype of the single-layer OLED is comparable in luminosity and efficiency to commercially available OLEDs.

A Safer, More Efficient Fiber Laser from Doping with Nanoparticles
Scientists at the U.S. Naval Research Laboratory (NRL) are using nanoparticles to build fiber lasers that are safer for the eyes and more efficient. The core of the laser’s silica fiber is doped with rare earth ions of holmium. With the aid of this dopant, the researchers were able to achieve an 85% level of efficiency with a laser operating at a wavelength of 2 µm.

World Molecular Imaging Congress 2019
September 4-7, 2019 - Palais des congrès de Montréal - Montreal Canada
Photonics Media Booth: 108
The WMIC will bring together thousands of professionals and students from across the entire molecular imaging field. Featuring dozens of sessions and hundreds of abstracts, this event will present new ideas, innovations, scientific research, industry exhibitors, and educational sessions. Spotlight Sessions based on the suggestions from previous survey results, regional topics, and recommendations from the Program Committee will cover innovative trends and address current knowledge gaps. Educational Sessions on the first day will serve as an introduction to more in-depth topics to be covered during the meeting.
