In Earth science, small details can help explain massive events. Rita Parai, an assistant professor of Earth, environmental and planetary sciences in Arts & Sciences at Washington University in St. Louis, uses precision equipment to measure trace levels of noble gases in rocks, samples that can provide key insights into planetary evolution.
Researchers developed a 60-milliwatt solid-state DUV laser at 193 nm using LBO crystals, setting new benchmarks in efficiency values.
In the realm of science and technology, harnessing coherent light sources in the deep ultraviolet (DUV) region holds immense significance across various applications such as lithography, defect inspection, metrology, and spectroscopy. Traditionally, high-power 193-nanometer (nm) lasers have been pivotal in lithography, forming an integral part of systems used for precise patterning. However, the coherence limitations associated with conventional ArF excimer lasers hinder their effectiveness in applications requiring high-resolution patterns, like interference lithography.

A great many cosmic puzzles still remain unsolved. By embracing a broad and varied approach, particle physics heads toward a bright future.
The potential impacts of AI are so far-reaching, no one wants to be faced with the implications of failing to actively participate in molding its future development.
By Harvard John A. Paulson School of Engineering and Applied Sciences
Researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have developed a programmable metafluid with tunable springiness, optical properties, viscosity and even the ability to transition between a Newtonian and non-Newtonian fluid.
People who want to see the total solar eclipse on April 8 may be blocked by cloudy skies if weather forecasts for America are accurate.
