Gene-infused nanoparticles used for combating disease work better when they include plant-based relatives of cholesterol because their shape and structure help the genes get where they need to be inside cells.

Researchers described a new strategy of designing metamolecules that incorporates two independently controllable subwavelength meta-atoms. This two-parametric control of the metamolecule secures the complete control of both amplitude and the phase of light.

Scientists develop new method to isolate atomic sheets and create new materials
Two-dimensional materials from layered van der Waals (vdW) crystals hold great promise for electronic, optoelectronic, and quantum devices, but making/manufacturing them has been limited by the lack of high-throughput techniques for exfoliating single-crystal monolayers with sufficient size and high quality.

Gas and water permeation barrier films play a vital part in applications ranging from food and pharmaceutical packaging to electronic devices. Two-dimensional (2D) materials, like graphene, are highly promising as ultra-high barrier materials, and their atomic thinness, mechanical stability, optical transparency and thermal properties offers many new possibilities and device form factors.

The semiconductor industry has been developed for more than 40 years following the Moore’s Law. With the size of transistors being shrinking down to tenth of nanometer scale, the quantum effects start to dominate and cause problems such as operation stability and heat générations.

Lasers are essential to many fields – ranging from optical communications and remote sensing, to manufacturing and medicine. While the semiconductor laser was first demonstrated nearly 60 years ago, advances in diode lasers and access to semiconductor fabrication techniques have enabled continued innovation and miniaturization of the technology.

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.
