Advancing Biogas Quality: Tackling Siloxane Challenges for Smooth Energy Transition

Siloxanes, present in everyday items, can compromise the efficiency and durability of bioenergy systems, even at trace levels. Monitoring and quantifying these impurities are critical for improving biogas quality and expanding its role in renewable energy. However, sampling biogas and storing samples containing siloxanes for analysis remain a significant challenge.

Novel Photoresist Chemistry Enables Lithography Approaching Angstrom-Scale Resolution

Photoresist materials are crucial in the manufacturing of computer chips, where the circuits are initially printed in the photoresist using photolithography. As the demand for smaller and more precise circuitry in computer chips grows, photoresists must resolve features with smaller sizes and higher density.
