Researchers control elusive spin fluctuations in 2D magnets

NanoWerk.com - Mon, 06/29/2020 - 17:19
Researchers developed a new imaging technique that is fast and sensitive enough to observe these elusive critical fluctuations in two-dimensional magnets. This real-time imaging allows researchers to control the fluctuations and switch magnetism via a 'passive' mechanism that could eventually lead to more energy-efficient magnetic storage devices.

Nanoelectromechanical switches based reconfigurable computing

NanoWerk.com - Mon, 06/29/2020 - 10:37
Novel complementary nanoelectromechanical (CNEM) switches based on complementary ferroelectric nanocracks integrate the advantages of ferroelectric and nanoelectromechanical switches, such as nonvolatility, quasi-zero OFF-state leakage current and low operating voltage. These ferroelectric crack-based CNEM switches could realize energy-efficient and high-density reconfigurable computing, which can be specialized to a particular task through its universal programmability, offering large flexibility and short time from design to realization.

Medical nanotechnology research for COVID-19

NanoWerk.com - Fri, 06/26/2020 - 12:01
The only options to control and deal with the spread of the Severe Acute Respiratory Syndrome Virus 2 (SARS-CoV-2) are fast, cheap, reliable, and portable means of diagnosing COVID-19 infection (the name of disease caused by SARS-CoV-2); therapeutics to treat the infected; and vaccines to rapidly build up immunization of large parts of the global population. The current crisis demands an urgent analysis of all the available nanotechnology tools. While nanomedicine strategies are in use for the design of the vaccine carriers, there are not enough other nanotechnology approaches being explored to tackle the current outbreak.
