Novel STEM for 3D Imaging Improves 3D Visualization of Curvilinear Nanostructures
Scientists have developed a scanning transmission electron microscopy (STEM) method that generates fast and reliable 3D images of curvilinear structures from a single sample orientation. This STEM method can acquire images in a single shot, making it possible to study samples dynamically as they change over time. Further, it can rapidly provide a “sense” of three dimensions, similar to a movie viewed in 3D.

3D Printing Technique Makes Degradable Biomaterials
A stereolithographic technique has been developed for making 3D-printed biomaterials that can undergo controlled degradation. This technique uses noncovalent (ionic) crosslinking and could potentially enable the fabrication of adaptive and stimuli-responsive biomaterials for use in biosensing, drug delivery and tissue engineering applications. Stereolithographic printing typically uses photoactive polymers that link together with covalent bonds, which are strong, but irreversible.

Smartphone App Assesses TBI at Site of Trauma
A smartphone app that detects concussion and other traumatic brain injuries (TBIs) could be used to determine whether someone — whether a football player, a soldier in battle, or an elderly person who has fallen — should be further assessed for concussion or other brain injury. The app, called PupilScreen, uses a smartphone’s video camera and deep learning tools to identify changes in the pupil’s response to light.

Ultrapure Green Light from Perovskite Could Enrich Next-Gen Displays
An ultrathin LED, as bendable as a sheet of paper and able to emit pure green light, has been developed using nanomaterials and simple room-temperature processes. Until now high-temperature processes have been required to produce pure light using LED technology. Researchers used colloidal 2D perovskites to convert the electrical current passing through the LED into light.

Optogenetics Controls Interorganellar Communication at Nanoscale
Researchers are using optogenetics to tune communication between organelles within living cells. The optogenetics tools are being used to control the proteins that form the bridge between organelles, and to govern the length of the bridge at the nanoscale. Bridge length influences the critical functions of the cell; when it is disrupted, metabolic dysfunction and cell death can occur.

Learn Efficient Light Pipe Design Using Virtual Prototyping
Tue, Sep 19, 2017 1:00 PM - 2:00 PM EDT
Attendees will learn how to design better, more efficient light pipes using Lambda Research's TracePro software - a 3D CAD virtual prototyping program with the power and tools to simulate and design light pipes. The presenter will demonstrate effective methods and detailed procedures for simulating light propagation in a light pipe model, analyzing cross-talk effects, producing desired output objectives, and optimizing models for efficiency and output. This webinar is for anyone designing light pipes, especially for automotive and avionic displays, industrial manufacturing, consumer electronics applications and medical devices. It's presented by Lambda Research Corporation.
