The fully 3D printed electric spray engine is suitable for small satellite in orbit maneuver, and its production cost is only a small part of that of traditional thrusters.Image source: Massachusetts Institute of Technology, USAThe Massachusetts Institute of Technology team recently demonstrated an electric spray engine made entirely of 3D printing technology, which can be propelled by emitting ...
Are you ready? The signal is out! "In the control room of a research center in Romania, engineer Antonio Toma has activated the world's most powerful laser, which is expected to make revolutionary progress in various fields from the health sector to space. The laser located in the center near the Romanian capital Bucharest is operated by the French company Thales and utilizes the invention of Nobe...
This week, an illustration was published on the cover of the international journal Science, showcasing a powerful mode-locked laser emitted from a miniature photonic semiconductor.A research team led by Alireza Marandi, a professor of electrical engineering and applied physics at the California Institute of Technology, has successfully developed a conventional mode-locked laser large enough to fit...
After receiving a $14.9 million contract from the US Department of Defense (DOD) last month to study the pulse laser effect, the University of Rochester recently received nearly $18 million in funding from the National Science Foundation (NSF) for the key technology design and prototype of the EP-OPAL, also known as the OMEGA EP coupled optical parametric amplifier line (OPAL).EP-OPAL is a new fac...
A team of scientists at the Technical University of Denmark has created a selene-based solar cell by replacing thermal annealing with a new laser annealing strategy."In our work, we investigated the potential of this laser annealing strategy specifically for selenium thin film solar cells, and we report a new world record for fill factor, a new world record for ideal factor, and the most advanced ...
