Dynamic Beam Lasers: Introducing New Parameters for Laser Welding
Thu, Oct 20, 2022 10:00 AM - 11:00 AM EDT
Dr. Asaf Nissenbaum shares new parameters for the Dynamic Beam Laser created by Civan Lasers. The laser’s unique power distribution provides complete control of the melt pool and keyhole which greatly reduces spatter, hot cracks, and porosity. It also provides new opportunities for laser material processing applications by increasing production speed, volume, and their capabilities. The Dynamic Beam Laser can be quickly programmed to move seamlessly between different workpieces and processes. This ability maximizes each machine's output. Presented by Civan Lasers.
Harnessing Photons for Bond-Selective Imaging, Neuromodulation, and the Killing of Superbugs
Tue, Nov 1, 2022 10:00 AM - 11:00 AM EDT
Chemical microscopy utilizing fingerprint vibrational spectroscopic signals opens a new window to visualize the orchestra of molecules and biological structures inside living systems. Dr. Ji-Xin Cheng, professor at Boston University, and his research team have recently started to harness photons to modulate the behavior of cells, including the photoacoustic modulation of neurons at ultrahigh spatial precision and photolysis of intrinsic chromophores to eradicate drug-resistant bacteria.
