A blue laser with a 450 nm wavelength has a significantly higher laser absorptivity in processing aluminium. Here, we developed a 2000 W blue laser directed energy deposition (BL-DED) system for additive manufacturing. In this system, a coaxial camera, a paraxial high-speed camera, and a ...
“The new Meltio Engine Blue represents a crucial breakthrough in Meltio’s directed energy deposition (DED) technology, designed specifically to respond to the current demands of the manufacturing industry around the world. For our industrial customers, the Meltio Engine Blue represents a significant ...
To overcome these challenges, green and blue laser sources have been proposed for AM processes. This review provides an overview of the recent developments and applications of green and blue laser sources for powder bed fusion of copper and its alloys, focusing on the effects of process ...
The Counter-UAS Directed Energy Stryker (Photo Courtesy: Leonardo DRS) During last month’s demonstration forU.S. Armyofficials inSocorro, N.M., the mobile C-UAS capability successfully destroyed numerous drones using BlueHalo’s 26kW LOCUST Laser Weapon System. Additionally, the demonstration incl...
due to the deep valence band energy level of blue QDs, there is a large injection barrier between the QD and the HTL, causing remarkable hole accumulation in HTL. To investigate the potential effect of hole accumulation on HTL, we performed cyclic voltammetry characterizations on TFB, the most...
These include methods like matrix-assisted laser desorption ionization time of flight (MALDI-TOF)-MS, electrospray-MS, bottom-up (shotgun) MS, data-dependent acquisition MS, data-independent acquisition (DIA) MS, targeted SRM/MRM/PRM, top-down MS, cross-linking MS, PTM analysis, N- and C...
While not infallible, blue chips often outperform, presenting a compelling investment opportunity in any market. Here are three I think are worth exploring right now. Coca-Cola (KO) Source: Fotazdymak / Shutterstock.com Wall Street can’t seem to get enough ofCoca-Cola(NYSE:KO), especially ...
