A new method enables precise nanofabrication inside silicon using spatial light modulation and laser pulses, creating advanced nanostructures for potential use in electronics and photonics.

Silicon, the cornerstone of modern electronics, photovoltaics, and photonics, has traditionally been limited to surface-level nanofabrication due to the challenges posed by existing lithographic techniques. Available methods either fail to penetrate the wafer surface without causing alterations or are limited by the micron-scale resolution of laser lithography within Si.

In the spirit of Richard Feynman’s famous dictum, ‘There’s plenty of room at the bottom’, this breakthrough aligns with the vision of exploring and manipulating matter at the nanoscale. The innovative technique developed by the Bilkent team surpasses current limitations, enabling controlled fabrication of nanostructures buried deep inside silicon wafers with unprecedented control.

A Cincinnati-based aerospace company has successfully represented a new, cutting-edge hypersonic dual-mode ramjet. The engine could enable high-speed flight and longer range across numerous multi-mission aircraft.

GE Aerospace took 11 months to develop the ramjet, which could increase in airflow compared to previously flight-tested hypersonic technology demonstrators.

“The rapid progression from design to testing underscores our commitment to driving innovation in hypersonic technologies,” said Amy Gowder, president and CEO of Defense & Systems at GE Aerospace.

Scientists have combined real human brain tissue with electronics to make a new kind of biocomputer.

A super-sized Nano Transparent Screen (NTS) has been developed and commercialized for the first time in the world. This innovative screen can adjust its transparency according to the environment and can be produced at a low cost, paving the way for the widespread adoption of large transparent screens, which until now have been prohibitively expensive.

A global research team has devised a method to decompose plastics and other materials into their smallest components using a laser, enabling their future reuse.

The breakthrough involves placing these materials on two-dimensional structures called transition metal dichalcogenides and then exposing them to laser light. This technique could significantly enhance the disposal of plastics that are currently almost impossible to break down with existing technologies.

Researchers have developed a new method to significantly enhance quantum technology performance by using the cross-correlation of two noise sources to extend coherence time, improve control fidelity, and increase sensitivity for high-frequency sensing. This innovative strategy addresses key challenges in quantum systems, offering a tenfold increase in stability and paving the way for more reliable and versatile quantum devices.

The work is published in the journal Physical Review Letters.
