It is reported that the research team of California Institute of Technology has developed an additive manufacturing (AM) technology based on hydrogel injection, which uses two-photon lithography technology to produce 3D metal with a characteristic resolution of about 100 nm.The relevant research is published in the journal Nano Letters, titled 'Suppressed Size Effect in Nanopillars with Hierarchy ...
Research backgroundIn transportation, industrial production, and practical life, icing often brings great troubles, and the most serious is that during the flight of an aircraft, key components once frozen will seriously affect navigation safety.The traditional passive deicing and anti icing strategies for aircraft, such as mechanical vibration and anti freezing liquids, have problems such as inco...
Researchers at the Federal College of Technology in Lausanne (EPFL) have shown that femtosecond lasers suitable for palm size can be manufactured using glass substrates.Can femtosecond lasers made entirely of glass become a reality? This interesting question prompted Yves Bellouard, the head of the Galata laboratory at the Federal Institute of Technology in Lausanne, to embark on a journey after y...
Recently, HieFo, a leading enterprise in the field of optical communication, officially launched its HCL30 DFB laser chip, designed specifically to meet the stringent requirements of coherent optical transmission. This chip combines efficient optical output power with excellent narrow linewidth performance, providing multiple industry standard wavelength options in the O-band and C-band, bringin...
Recently, scientists from the Hanover Laser Center (LZH) in Germany announced the successful development of an automated laser drilling process that can promote the processing of carbon fiber reinforced plastics (CFRP). They stated that this is particularly valuable in applications such as lightweight structures and sound insulation.Composite materials such as carbon fiber reinforced plastics (CFR...
