“Fundamental Discovery” Used To Turn Nanotube Into Tiny Transistor — 25,000x Smaller Than Width of a Human Hair

Posted by in categories: computing, nanotechnology

An international team of researchers has used a unique tool inserted into an electron microscope to create a transistor that’s 25,000 times smaller than the width of a human hair.

The research, published in the journal Science, involves researchers from Japan, China, Russia, and Australia who have worked on the project that began five years ago.

QUT Center for Materials Science co-director Professor Dmitri Golberg, who led the research project, said the result was a “very interesting fundamental discovery” which could lead a way for the future development of tiny transistors for future generations of advanced computing devices.

Tuning a magnetic fluid with an electric field creates controllable dissipative patterns

Posted by in categories: chemistry, nanotechnology

Researchers at Aalto University have shown that a nanoparticle suspension can serve as a simple model for studying the formation of patterns and structures in more complicated non-equilibrium systems, such as living cells. The new system will not only be a valuable tool for studying patterning processes but also has a wide range of potential technological applications.

The mixture consists of an oily liquid carrying of iron oxide, which become magnetized in a magnetic field. Under the right conditions, applying a voltage across this ferrofluid causes the nanoparticles to migrate, forming a concentration gradient in the mixture. For this to work, the ferrofluid has to also include docusate, a waxy chemical that can carry charge through the fluid.

The researchers discovered that the presence of docusate and a voltage across the ferrofluid resulted in a separation of electric charges, with the iron oxide nanoparticles becoming negatively charged. “We didn’t expect that at all,” says Carlo Rigoni, a postdoctoral researcher at Aalto. “We still don’t know why it happens. In fact, we don’t even know whether the charges already get split when the docusate is added or if it happens as soon as voltage is turned on.”

NASA: Webb’s precision launch, correction maneuvers will significantly extend 10-year lifetime

Posted by in category: energy

The observatory should now have enough propellant to support science operations well past its 10-year science lifetime. The space agency said the precision of the Arianespace Ariane 5 launch resulted in less propellant being used than anticipated. A smooth mid-course correction maneuver after launch, which added approximately 45 mph to the craft’s speed, also helped conserve fuel.

A second correction burn occurred on December 27, speeding up Webb by 6.3 mph.

NASA said that from this point on, all scheduled deployments on Webb will be controlled by humans. This means their deployment, or even their order, could change. Webb at this point is a little over a day into a six-day process to unfold its sunshield.

Educating the Citizens of the Universe

Posted by in categories: existential risks, law, robotics/AI

We live in a very fast-changing world and quite an unpredictable one. In part, it is because we got lots of technological powers while our brain stays just the same as in pre-technological times. What do we teach children in this world? How can we help them to reflect on their thinking, get wiser in using the new technological powers, develop growth mindset and resilience, see the big picture and the interconnections within the complex systems (be that our body, ecological system, or the whole Universe)? We are trying to address these issues by teaching space science, AI and cognitive science, and existential risks and opportunities to pre-teens. In three years, the kids get an opportunity to talk to some of the most prominent thinkers in the field, reflect on deep questions, develop connections with specialists from multiple fields, from space law to ecology to virology, present their work at conferences. Check out our classes:
