Researchers invent low-temperature synthesis method for high-quality tellurium nanomesh for next-generation electronics

Posted by in categories: energy, nanotechnology

A collaborative team led by researchers from City University of Hong Kong (CityU) recently invented an innovative method for synthesizing high-quality, semiconducting nanomesh at a lower temperature and production cost than conventional methods. The findings will help enable the large-scale production of nanomesh for next-generation electronics.

Nanomesh is a nano-scale material formed from a network of nanowires. For several decades, one-dimensional materials like nanowires made of crystalline inorganic materials have been widely explored as the main driver for emerging electronics, as they have features like mechanical flexibility, energy efficiency and optical transparency. However, the scalability, integrability and cost-effectiveness of nanowire semiconductors are insufficient, limiting their potential for large-area electronic and optoelectronic applications.

To overcome these shortcomings, a research team led by CityU scientists made a breakthrough, inventing a low-temperature vapor-phase growth method, which can achieve large-scale synthesis of semiconducting tellurium (Te) nanomesh for use in devices.

Research team invents revolutionary new batteries that are safer, cleaner, and last longer than lithium-ion

Posted by in categories: chemistry, life extension

According to a news release from the Vienna University of Technology (TU Wien), oxygen-ion batteries don’t have the same aging issue that lithium batteries face, which means they can maintain effectiveness for an incredibly long period.

They can also be manufactured using incombustible materials and don’t require the same rare elements as lithium batteries, which means they won’t have nearly as substantial of an environmental footprint and won’t spontaneously explode if mishandled.

“In many batteries, you have the problem that at some point the charge carriers can no longer move,” said Alexander Schmid of TU Wien’s Institute for Chemical Technologies. “Then they can no longer be used to generate electricity, the capacity of the battery decreases. After many charging cycles, that can become a serious problem.”

Both humans and AI hallucinate — but not in the same way

Large language models have been shown to ‘hallucinate’ entirely false information, but aren’t humans guilty of the same thing? So what’s the difference between both?

Scientists claim they’re the first to transmit space-based solar power to Earth

Posted by in categories: computing, solar power, space, sustainability

The idea of solar energy being transmitted from space is not a new one. In 1968, a NASA engineer named Peter Glaser produced the first concept design for a solar-powered satellite. But only now, 55 years later, does it appear scientists have actually carried out a successful experiment. A team of researchers from Caltech announced on Thursday that their space-borne prototype, called the Space Solar Power Demonstrator (SSPD-1), had collected sunlight, converted it into electricity and beamed it to microwave receivers installed on a rooftop on Caltech’s Pasadena campus. The experiment also proves that the setup, which launched on January 3, is capable of surviving the trip to space, along with the harsh environment of space itself.

“To the best of our knowledge, no one has ever demonstrated wireless energy transfer in space even with expensive rigid structures. We are doing it with flexible lightweight structures and with our own integrated circuits. This is a first,” said Ali Hajimiri, professor of electrical engineering and medical engineering and co-director of Caltech’s Space Solar Power Project (SSPP), in a press release published on Thursday.

Robot-assisted deep brain stimulation surgery could treat epilepsy

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

Three of these procedures have thus far been undertaken in Canada.

A neurosurgeon in Canada has become the first in the nation to perform robot-assisted deep brain stimulation surgery on a patient suffering from epilepsy with success.

This is according to a report by CTV News published on Wednesday.

Is OpenSource AI Threatening The Tech Titans?

Posted by in categories: innovation, robotics/AI

Open-source AI can be defined as software engineers collaborating on various artificial intelligence projects that are open to the public to develop. The goal is to better integrate computing with humanity. In early March, the open source community got their hands on Meta’s LLaMA which was leaked to the public. In barely a month, there are very innovative OpenSource AI model variants with instruction tuning, quantization, quality improvements, human evals, multimodality, RLHF, etc.

Open-source models are faster, more customizable, more private, and capable. They are doing things with $100 and 13B params that even market leaders are struggling with. One open-source solution, Vicuna, is an… More.


This article explores AI in the context of open-sourced alternatives and highlights market dynamics in play.

Russia Claims ‘First Kill by Artificial Intelligence’ in Ukraine

Posted by in categories: robotics/AI, transportation

Russia claims that its S-350 Vityaz air defence system shot down a Ukrainian aircraft while operating in “automatic mode”. The Russian Deputy PM said that its highly acclaimed S-350 Vityaz air defence system was operating in the NVO zone. It demonstrated capabilities of autonomously detecting, tracking, and destroying Ukrainian air targets without any operator’s intervention. Watch the video to find out how did the system work on AI?
