The most famous use of GPS satellites is to help people understand their location, whether it is driving cars, ships or planes, or hiking in remote areas. Another important but little-known use is to distribute information to other Earth observation satellites to help them accurately locate measurements of our planet.NASA and several other federal agencies, including the US Space Force, the US Spa...
Recently, a research team led by Professor Cai Wei and Professor Xu Jingjun from the School of Physical Sciences at Nankai University has experimentally confirmed for the first time the generation of polaritons, also known as Smith Purcell radiation, at the two-dimensional scale, and further demonstrated the ability of free electrons to regulate two-dimensional Smith Purcell radiation. The researc...
Ditzingen, 05. March 2025 – At its in-house exhibition INTECH, high-tech company TRUMPF is showcasing a new cooler for its laser cutting machines. The new unit is capable of reducing energy consumed during the cooling process and uses fifty percent less energy than conventional solutions. Unlike conventional coolers, the main components of this new solution— such as pumps, fans and compressors— ar...
The research team used a new reverse design framework to demonstrate ultra optical broadband thermal imaging for applications ranging from consumer electronics to thermal sensing and night vision.The new framework, known as the "Modulation Transfer Function" project, solves the challenges related to broadband metaoptics by determining the functional relationship between image contrast and spatial ...
Laser Cladding, also known as laser cladding or laser cladding, is a method of adding cladding material to the surface of the substrate and using a high-energy density laser beam to melt it together with the thin layer on the surface of the substrate. It forms a metallurgical bonded additive cladding layer on the surface of the substrate, which can be used for surface strengthening and defect repa...
