Scientists have advanced this field by stabilizing exciton polaritons in semiconductor photonic gratings, achieving long-lived and optically configurable quantum fluids suitable for complex system simulations.Researchers from Leicester CNR Nanotec and the School of Physics at the University of Warsaw used a new generation of semiconductor photonic gratings to optically customize the composite of q...
1. Research backgroundDirected energy deposition (DED), as an efficient and economical technology in the field of additive manufacturing (AM), is widely used in the manufacturing of metal materials. However, its high heating and cooling rates, as well as significant temperature gradients, often lead to rapid solidification, forming cross layer columnar grains and internal defects, seriously affect...
The attosecond level ultra short laser pulse provides a powerful method for detecting and imaging ultra short processes, such as the motion of electrons in atoms and molecules.Although ultra short laser pulses can be generated, generating ultra short and high-energy pulses is a continuous challenge. In order to expand the photon energy, photon flux, and continuous bandwidth of isolated attosecond ...
Due to the growing demand for renewable energy, the need for modern technologies to dismantle existing underwater infrastructure is also growing.For example, in order to boost the power of an offshore wind farm to a higher level, the existing old steel frame, which may be below sea level, must first be removed so that engineers can rebuild the steel frame for higher power.In laboratory tests, rese...
Recently, Yamazaki Mazak, a well-known Japanese machine tool manufacturer, announced that it will unveil its economic laser processing star Optiplex 3015 Ez for the first time in the European market at the upcoming 2024 EuroBLECH exhibition. This carefully crafted laser processing machine not only combines high-quality processing capabilities with affordable prices, but also aims to open the doo...
