2-D Nanotech Material for Computer Chips

by

Two-dimensional material-based transistors are being extensively investigated for CMOS (complementary metal oxide semiconductor) technology extension; nevertheless, downscaling appears to be challenging owing to high metal-semiconductor contact resistance. Two-dimensional (2D) nano-materials could be a replacement for conventional CMOS semiconductors for high-speed integrated circuits and very low power usage. CMOS is reaching the physical limits of about …

Metalenses Sorts Color Without Color Filters

by

Polarization-insensitive metasurface lenses (metalenses) sort primary colors on high-density pixels without the use of color filters. The metalenses simultaneously act as pixel-scale color splitters and lenses and are compatible with complementary metal–oxide-semiconductor sensor technology. An image sensor with such metalenses significantly enhances the detected light power, while affording high image quality, incident angle tolerance, and …

A World With Cheap Aging Damage Reversal

by

What would a world with cheap aging damage reversal look like? This could happen with biotech or gene therapy injections that repair aging damage. Oisin Biotechnologies has been developing a highly precise, patent-pending, DNA-targeted intervention to clear these cells. There is also work by Rejuvenate Bio to create injectable combination gene therapy that could reverse …

Unipolar Carbon Nanotube Muscles: Ten to Thirty Times Human Muscle and Two to Six times Diesel V8

by

Researchers describe creating powerful, unipolar electrochemical yarn muscles that contract more when driven faster, thereby solving important problems that have limited the applications for these muscles. This polymer coating converts the normal bipolar actuation of carbon nanotube yarns to unipolar actuation, where the muscle actuates in one direction over the entire stability range of the …

Meta DNA Revolutionizes DNA Nanotechnology By Scaling Up Size By 1000 to 1 Million Times

by

The new meta-DNA self-assembly concept may totally transform the microscopic world of structural DNA nanotechnology. Decades ago a huge milestone in DNA technology was the invention of DNA origami, where a long single-stranded DNA is folded into designated shapes with the help of hundreds of short DNA staple strands. DNA nanotechnology had challenges assembling larger …

Can 21st Century Progress Surpass 20th Century Progress

by

Can the technological, scientific, medical and economic progress of the 21st century surpass the 20th century? The richest countries in the world increased per capita income by 10 times from 1900 to 2000. It will take about 23 years in the 21st century for the US to double per capita income. (2000-2023) If this pace …
