Russia launched a hypersonic rocket at a Ukrainian weapons depot in the west. Although it may sound alarming, the Russian technology used to launch that attack was not very advanced. But, Russia, China and the United States are working together to develop next-generation hypersonic weapons, which pose a serious threat to national security and global security. I am an aerospace […]
What Does Bacteria Sound Like Nanotechnology Reveals Bacterial Soundtracks
One bacterium’s sound Farbod Alijani’s Delft University of Technology team (TU Delft), was initially investigating the basic mechanics of graphene when a strange idea struck them. They were curious to see what would happen if graphene, an extremely sensitive material, came in contact with one biological object. Alijani says graphene, a type of carbon that is composed […]
Capturing and converting solar energy to electricity when needed
This is a revolutionary way to generate electricity from solar energy. This means that solar energy can be used to generate electricity no matter what season or weather conditions. It is a closed system which can operate without causing CO2 emissions,” said Kasper Moth Poulsen, Chalmers Professor of Chemistry and Chemical Engineering. The new technology is based […]
A new atomically thin material that improves light-based tech efficiency: solar panels, cameras, biosensors
Photodetectors are sensors that convert light into electricity. These technologies include cameras, solar panels and fiber optics. Photodetectors are becoming smaller and more affordable due to the shrinking of their semiconductor chips. However, current manufacturing techniques and materials are limiting miniaturization and forcing compromises between performance and size. The traditional manufacturing of semiconductor chips has many drawbacks […]
Nanotechnology enables the creation of a new “Electric Eye” neuromorphic artificial vision device.
“This work is the first step towards our ultimate destination-to create a micro-scale camera to microrobots,” Sidong Lei assistant professor of Physics, who led this research. “We demonstrate the principle and feasibility of this new type image sensor, with an emphasis on miniaturization. Lei’s team used Nanotechnology to create the foundation for the biomimetic artificial sight […]
An open-source “Unique Building Identifier”, which can be used to track and reduce energy use and emissions, is possible.
For a small percentage of map users, flaws are hidden beneath the surface. Maps that show buildings without their exact addresses are confusing for precision-minded users. Perhaps they show an exact address but are applied to multiple buildings. Maybe the building doesn’t have an address. Perhaps a map was created with an anomaly not seen on any other map. Even […]
Atomic layer etching could lead to ever-more powerful microchips and supercomputers
The information age has brought the world smart phones, lightning-fast computers, and the internet over the past 60 years. The ability to pack more transistors onto a computer chip every 2 years has made this possible. This means that billions of transistors can fit on a fingernail-sized device. Individual atoms can be counted and observed within these […]
New materials allow for cheaper solar cells that are easier to make
Perovskite solar cell are an interesting alternative. They can be printed with inks and are low-cost, lightweight, efficient, flexible, and thin. However, they are less efficient than silicon solar cells and more importantly, have a lower stability rate, which can cause them to fail in normal environmental conditions. These problems may be solved by new metal-containing […]
Can we ditch the datasets when it comes to AI? Using Synthetic Data for Training Machine-Learning Models
A machine learning model for image classification using synthetic data can be as good as one that is trained with real data, according to a study. It takes a lot of data to train machine learning models to recognize damage in satellite images following natural disasters. These data can be difficult to find. If you have the […]
Massive Geomagnetic Storm: Coronal mass ejection from the Sun could knock out the Power Grid, and Internet
All telegraph networks around the world failed on September 1, 1859. Telegraph operators reported experiencing electrical shocks and telegraph paper burning. They were also able to use equipment with batteries. In the evenings, the aurora borealis (sometimes called the northern lights) could be seen as far south and as far as Colombia. This phenomenon is usually only visible at […]
