Scientists develop powerful family of 2D materials

Posted by in categories: materials, nanotechnology

A team from the Tulane University School of Science and Engineering has developed a new family of two-dimensional materials that researchers say has promising applications, including in advanced electronics and high-capacity batteries.

Led by Michael Naguib, an assistant professor in the Department of Physics and Engineering Physics, the study has been published in the journal Advanced Materials.

“Two-dimensional are nanomaterials with thickness in the nanometer size (nanometer is one millionth of a millimeter) and lateral dimensions thousands of times the thickness,” Naguib said. “Their flatness offers unique set of properties compared to bulk materials.”

Cryostasis Revival: The Recovery of Cryonics Patients through Nanomedicine

Posted by in categories: biotech/medical, computing, cryonics, life extension, nanotechnology

Cryostasis Revival by Robert Freitas is the first comprehensive technical exposition how to revive cryonics patients in the future. This 700+ page book with thousands of references, and technical color illustrations, is now available on Amazon in a limited textbook hardcover edition.

Cryostasis is an emergency medical procedure in which a human patient is placed in biological stasis at cryogenic temperatures. A cryopreserved patient can be maintained in this condition indefinitely without suffering additional degradation, but cannot yet be revived using currently available technology. This book presents the first comprehensive conceptual protocol for revival from human cryopreservation, using medical nanorobots. The revival methods presented in this book involve three stages: collecting information from preserved structure, computing how to fix damaged structure, and implementing the repair procedure using nanorobots manufactured in a nanofactory – a system for atomically precise manufacturing that is now visible on the technological horizon.

‘Nanomagnetic’ computing can provide low-energy AI, researchers show

Posted by in categories: biotech/medical, nanotechnology, robotics/AI

Researchers have shown it is possible to perform artificial intelligence using tiny nanomagnets that interact like neurons in the brain.

The new method, developed by a team led by Imperial College London researchers, could slash the of (AI), which is currently doubling globally every 3.5 months.

In a paper published today in Nature Nanotechnology, the international team have produced the first proof that networks of nanomagnets can be used to perform AI-like processing. The researchers showed nanomagnets can be used for ‘time-series prediction’ tasks, such as predicting and regulating insulin levels in .

World’s smallest gears measure mere nanometers to power molecular machines

Posted by in categories: biotech/medical, nanotechnology

In many fields of technology, smaller is better, and machinery is now getting so tiny it’s measured in mere atoms. Researchers at the University of Erlangen–Nuremberg (FAU) in Germany have now developed what they claim are the world’s smallest working gear wheels.

Molecular machines and nanorobots could be extremely useful in the coming decades, helping to construct electronic components, transport drugs through the body, or manipulate individual cells or molecules.

To that end, scientists have developed nanoscale versions of many machine parts, such as motors, pistons, pumps, wrenches and propellers.

New “Electric Eye” Neuromorphic Artificial Vision Device Developed Using Nanotechnology

Posted by in categories: nanotechnology, robotics/AI

Using nanotechnology, scientists have created a newly designed neuromorphic electronic device that endows microrobotics with colorful vision.

Researchers at Georgia State University have successfully designed a new type of artificial vision device that incorporates a novel vertical stacking architecture and allows for greater depth of color recognition and micro-level scaling. The new research study was published on April 18, 2022, in the top journal ACS Nano.

“This work is the first step toward our final destination–to develop a micro-scale camera for microrobots,” says assistant professor of Physics Sidong Lei, who led the research. “We illustrate the fundamental principle and feasibility to construct this new type of image sensor with emphasis on miniaturization.”

Malicious web application attacks rise

Posted by in categories: biotech/medical, nanotechnology

A large team of researchers at the University of Washington, working with colleagues from Université Montpellier and the Fred Hutchinson Cancer Research Center, has taken a major step toward the creation of an axle-rotor nanomachine. In their paper published in the journal Science, the group describes how they used DNA coding to customize E. coli to push them into creating proteins that assembled into rotors and axles.
