Researchers have developed a flexible and wearable triboelectric nanogenerator to efficiently harvest low-frequency mechanical energy from the human body. The device, made using paper-cutting methods, has great application prospects in extendable battery life and self-powered wearable electronics.
The Global Hemp Innovation Center is working with 13 Native American Tribes and other partners to spur economic development through sustainable supply chains and education. The project aims to create jobs in the emergent biobased economy and explore industrial uses of hemp.
Scientists created a method to study variations in power output from solar PV plants over time, accounting for distinct power fluctuations across different geographical areas. The grid integration challenge arises when including variable renewable energy sources like wind and solar into the power grid.
A new study found that the brains of polyglots process their native language with minimal effort, while more proficient languages activate the language network stronger. The researchers explored how polyglots' brains respond to different languages and proficiency levels.
A novel transparent ultrasonic transducer (TUT) developed by POSTECH researchers offers exceptional optical transparency and maintains acoustic performance, surpassing conventional limitations. This breakthrough enables high-depth-to-resolution ratios for ultrasound imaging, with applications in various medical devices and fields.
The article reviews energy management strategies for hybrid electric vehicles and aircraft, highlighting challenges and solutions. It also discusses the application of energy management in flying cars driven by hybrid electric propulsion systems.
Researchers developed an algorithm that combines polarization and visible images to reveal multi-dimensional features, improving target detection accuracy. The NSCT transform is used to fuse the images, compensating for limitations of single-image sensors.
