Novel lenses enable X-ray microscopy with record resolution

ScienceDaily.com: Nanotechnology News - 7 декабря, 2017 - 18:25
Scientists have developed novel lenses that enable X-ray microscopy with record resolution in the nanometer regime. Using new materials, the research team has perfected the design of specialized X-ray optics and achieved a focus spot size with a diameter of less than 10 nanometers. The researchers successfully used their lenses to image samples of marine plankton.

Strongly anisotropic spin relaxation observed in graphene when interfaced with transition metal dichalcogenides

Nanowerk.com - 7 декабря, 2017 - 15:03
Experimentalists have found evidence that the spin-orbit coupling induced in graphene by proximity to transition metal dichalcogenides affects electron spins differently depending on their orientation. This work suggests new approaches to controlling the transport of spin and valley information in future spintronics devices.

A 100-fold leap to GigaDalton DNA nanotech

ScienceDaily.com: Nanotechnology News - 7 декабря, 2017 - 00:23
A research team has leapfrogged their 'DNA bricks' technology by two orders of magnitude, enabling next-generation DNA bricks to self-assemble into three-dimensional nanostructures that are 100 times more complex than those created with existing methods. The study provides user-friendly computational tools to design DNA nanostructures with complex cavities (and possibly surfaces) that have the potential to serve as building components in numerous nanotechnological applications in medicine and engineering.

DNA-origami surpasses important thresholds

ScienceDaily.com: Nanotechnology News - 6 декабря, 2017 - 22:16
It is the double strands of our genes that make them so strong. Using a technique known as DNA origami, biophysicists have been building nanometer-scale objects for several years. Now scientists have not only broken out of the nanometer realm to build larger objects, but have also cut the production costs a thousand-fold. These innovations open a whole new frontier for the technology.
