Ryerson University Physicist Dr. Michael Kolios, his former graduate student Dr. Michael Moore, and collaborator zebrafish model expert Dr. Xiao-Yan Wen developed a new mode of photoacoustic imaging called F-mode. This new mode selectively enhances photoacoustic image features based on the size of the object and the sounds it produces.
University of Maryland physicists have developed a powerful new method to detect radioactive material. By using an infrared laser beam to induce an electron avalanche breakdown near the material, the new technique can detect shielded material from a distance -- improving upon current technologies that require close proximity to radioactive material. With additional engineering, the method could be scaled up to scan shipping containers at ports of entry, providing a powerful new tool for security applications.
A Rice University-led study discovers a mechanism by which molecules affect the plasmonic response of gold nanorods. The mechanism could be used to enhance applications like catalysis that involve plasmon-driven chemistry.
Formamidinium lead iodide is a very good material for photovoltaic cells, but getting the correct and stable crystal structure is a challenge. The techniques developed so far have produced rather poor results. However, University of Groningen scientists, led by Professor of Photophysics and Optoelectronics Maria Antonietta Loi, have now cracked it -- using a blade and a dipping solution. The results were published in the journal Nanoscale on March 15, 2019.
Nanowire gurus at the National Institute of Standards and Technology have made ultraviolet light-emitting diodes (LEDs) that, thanks to a special type of shell, produce five times higher light intensity than do comparable LEDs based on a simpler shell design.
Researchers have developed a microscope specifically for imaging large groups of interacting cells in their natural environments. The instrument provides scientists with a new tool for imaging neurons in living animals and could provide an unprecedented view into how large networks of neurons interact during various behaviors.
University of Pennsylvania Engineers have designed a metamaterial device that can solve integral equations. The device works by encoding parameters into the properties of an incoming electromagnetic wave; once inside, the device's unique structure manipulates the wave in such a way that it exits encoded with the solution to a pre-set integral equation for that arbitrary input.
Inspired by the flashing colors of the neon tetra fish, researchers have developed a technique for changing the color of a material by manipulating the orientation of nanostructured columns in the material.
The method developed by Juho Karhu in his PhD thesis work is a first step towards creating a precise measuring device.
A team of researchers working at Berkeley Lab has discovered the strongest topological conductor yet, in the form of thin crystal samples that have a spiral-staircase structure. The team's result is reported in the March 20 edition of the journal Nature.
