The maximum absorption wavelength of silicon solar cells (SSCs) is approximately 1100 nm, due to the inherent bandgap limitations of silicon materials. This constraint results in significant optical ...

In the pursuit of sustainable energy solutions, the quest for more efficient solar cells is paramount. Organic photovoltaic cells have emerged as a promising alternative to traditional silicon-based ...

Boeing, together with Norway's Nammo, is developing a long-range ramjet-powered 155mm shell for the US Army. Boeing has offered the best look to date of its 155mm artillery shell with a ramjet engine ...

Robotic ammonites, evaluated in a university pool, allow researchers to explore questions about how shell shapes affected swimming ability. They found trade-offs between stability in the water and ...
