The latest research led by the University of Surrey shows that alumina (Al2O3) nanoparticles can significantly enhance the lifespan and stability of perovskite solar cells, extending the service life of such high-efficiency energy devices tenfold.Although perovskite solar cells have advantages such as low cost and light weight compared to traditional silicon-based technologies, their commercial po...
The formation of dissipative solitons is influenced by various factors, such as spectral filtering effect and Kerr nonlinearity effect. This interaction leads to the possibility of mode locking on a large range of parameters, generating pulses with completely different types and evolution from conventional physical laws and optical properties, tolerating higher nonlinear effects, and effectively a...
Recently, nLIGHT, a manufacturer of high-power semiconductors and fiber lasers, announced its financial performance for the fourth quarter and full year of 2024.financial summaryTotal revenue: 198.5 million US dollars, a decrease from 209.9 million US dollars in 2023, due to a decline in sales in the laser product department.Operating loss: A loss of $65.6 million, compared to a loss of $46.8 mill...
Researchers have developed a new method of making micro stretchable antenna with water gel and liquid metal. These antennas can be used for wearable and flexible wireless electronic devices to provide links between devices and external systems for power transmission, data processing, and communication.Using our new manufacturing method, we have demonstrated that the length of liquid metal antennas...
Latest news: Rheinmetall and European Missile Group Germany plan to establish a joint venture to develop shipborne laser weapons.The cooperation between the two companies in the field of military laser technology has been ongoing for several years. In 2022 and 2023, under the framework of the High Energy Marine Laser Demonstration Working Group (ARGE), the jointly developed laser was successfully ...
