Home > Press > New Cypher VRS1250 Video-Rate Atomic Force Microscope Enables True Video-Rate Imaging at up to 45 Frames per Second
Abstract:
Oxford Instruments Asylum Research today announced the launch of the new Cypher VRS1250 video-rate atomic force microscope (AFM). Twice as fast as the first-generation Cypher VRS, the new AFM enables scan rates up to 1250 lines/second and frame rates up to 45 frames/second. This new higher speed will enable researchers to capture nanoscale details of dynamic events that were previously inaccessible, including biochemical reactions, 2D molecular self-assembly, and etch and dissolution processes and more. The Cypher VRS1250 is unique among high-speed AFMs in that it can also support a full range of modes and accessories, not just high-speed imaging, which makes it a very versatile tool for large interdisciplinary research groups and shared imaging facilities with multiple projects.

Home > Press > Researchers analyzed circulating currents inside gold nanoparticles: A new method facilitates accurate analysis of magnetic field effects inside complex nanostructures
The atomic structure of a gold nanoparticle protected by phosphine molecules (left) and magnetic-field-induced electron currents in a plane intersecting the center of the particle (right). The total electron current consists of two (paratropic and diatropic) components circulating in opposite directions.

Abstract:
Researchers in the Nanoscience Center of University of Jyvaskyla, in Finland and in the Guadalajara University in Mexico developed a method that allows for simulation and visualization of magnetic-field-induced electron currents inside gold nanoparticles. The method facilitates accurate analysis of magnetic field effects inside complex nanostructures in nuclear magnetic resonance measure

Abstract:
Scientists at the University of Nottingham have developed an ultrasonic imaging system, which can be deployed on the tip of a hair-thin optical fibre, and will be insertable into the human body to visualise cell abnormalities in 3D.
