Atomic force microscopy in 3D

Jul 05, 2024 (Nanowerk News) Atomic force microscopy (AFM) was originally invented for visualizing surfaces with nanoscale resolution. Its basic working principle is to move an ultrathin tip over a sample’s surface. During this xy-scanning motion, the tip’s position in the direction perpendicular to the xy-plane follows the sample’s height...

Fresh wind blows from historical supernova

Jul 05, 2024 (Nanowerk News) A mysterious remnant from a rare type of supernova recorded in 1181 has been explained for the first time. Two white dwarf stars collided, creating a temporary “guest star,” now labeled supernova (SN) 1181, which was recorded in historical documents in Japan and elsewhere in...

Single atoms show their true color

Jul 04, 2024 (Nanowerk News) One of the challenges of cramming smarter and more powerful electronics into ever-shrinking devices is developing the tools and techniques to analyze the materials that make them up with increasingly intimate precision. Physicists at Michigan State University have taken a long-awaited step on that front...

Getting bacteria into line

Jul 04, 2024 (Nanowerk News) Researchers at Finland’s Aalto University have found a way to use magnets to line up bacteria as they swim. The approach offers more than just a way to nudge bacteria into order – it also provides a useful tool for a wide range of research,...

Designing photonic crystals with a genetic algorithm

Jul 03, 2024 (Nanowerk News) The advent of quantum computers promises to revolutionize computing by solving complex problems exponentially more rapidly than classical computers. However, today's quantum computers face challenges such as maintaining stability and transporting quantum information. Phonons, which are quantized vibrations in periodic lattices, offer new ways to...

Mapping the surfaces of MXenes, atom by atom, reveals new potential for the 2D materials

Jul 03, 2024 (Nanowerk News) In the decade since their discovery at Drexel University, the family of two-dimensional materials called MXenes has shown a great deal of promise for applications ranging from water desalination and energy storage to electromagnetic shielding and telecommunications, among others. While researchers have long speculated about...
