Researchers at the Technion-Israel Institute of Technology and their partners at Bar Ilan University have developed new technology to inhibit the development of Alzheimer’s disease.

Squids, octopuses and cuttlefish are undisputed masters of deception and camouflage. Their extraordinary ability to change color, texture and shape is unrivaled, even by modern technology.

The terahertz frequency range – which sits in the middle of the electromagnetic spectrum between microwaves and infrared light — offers the potential for high-bandwidth communications, ultrahigh-resolution imaging, precise long-range sensing for radio astronomy, and much more.

A recent study from the labs of James Hone (mechanical engineering) and Cory Dean (physics) demonstrates a new way to tune the properties of two-dimensional (2D) materials simply by adjusting the twist angle between them. The researchers built devices consisting of monolayer graphene encapsulated between two crystals of boron nitride and, by adjusting the relative twist angle between the layers, they were able to create multiple moiré patterns.

By folding snippets of DNA into the shape of a five-pointed star using structural DNA nanotechnology, researchers have created a trap that captures Dengue virus as it floats in the bloodstream. Once sprung, the trap – which is non-toxic and is naturally cleared from the body – lights up. It’s the most sensitive test for the mosquito-borne diseases yet devised.

Single-wall carbon nanotubes (SWCNT) have found many uses in electronics and new touch screen devices. Carbon nanotubes are sheets of one atom-thick layer of graphene rolled up seamlessly into different sizes and shapes. To be able to use them in commercial products like transparent transistors for phone screens, researchers need to be able to easily test nanotubes for their materials properties, and the new method helps with this.

Researchers can optimize the performance of multi-layered, post-fabricated organic photovoltaic devices doped with gold nanoparticles by using combined X-ray diffraction and X-ray fluorescence.

Crystalline zinc blende GaAs has been grown on a trigonal c-plane sapphire substrate by molecular beam epitaxy.

Graphene has been the focal point for many research projects in recent years. It has proved to be one the most diverse materials known to man and recently a team of researchers from Northwestern Engineering have stumbled upon a method of creating graphene ink while trying to discover a new method producing graphene.
