Pushing the Boundaries of Computing Speed: How Light Antennas Could Revolutionize Computer Chips

September 22, 2024

As modern computers approach their physical limits, semiconductor components currently operate at maximum frequencies of just a few gigahertz, performing billions of computing operations per second. To maintain performance, systems often rely on multiple chips to distribute tasks, as the speed of individual chips cannot be further increased. However, a game-changing leap in speed could be achieved if photons (light) were used instead of electrons (electricity) in computer chips, potentially making them up to 1000 times faster.

A promising approach to unlocking this leap in speed is through plasmonic resonators, often called “antennas for light.” These nanometer-sized metal structures allow for interaction between light and electrons, and their performance can vary depending on their geometry. “The challenge,” says Dr. Thorsten Feichtner, a physicist at Julius-Maximilians-Universität (JMU) Würzburg in Germany, “is that plasmonic resonators cannot yet be modulated effectively, unlike transistors in conventional electronics. This limitation prevents the development of fast, light-based switches.”

Affordable 3D Bioprinting: Researchers Turn Regular Printers into Tissue Engineering Tools

September 19, 2024

Until now, printing living tissue constructs required specialized and expensive bioprinters. However, researchers from the Centre for Applied Tissue Engineering and Regenerative Medicine (CANTER) at Munich University of Applied Sciences have found a way to modify a simple, commercially available 3D printer to create biological structures at the touch of a button. This breakthrough opens up the field of bioprinting to smaller laboratories that previously couldn’t afford the specialized equipment.

Benedikt Kaufmann, a research associate at CANTER, led the team that developed this cost-effective solution. By modifying a standard 3D printer, they overcame a significant challenge in bioprinting: maintaining the right conditions for temperature and humidity. Using heating foils and water-soaked cellulose, the team achieved a stable environment of 37°C and over 90% humidity, crucial for printing biomaterials. The process takes place on a translucent glass platform, allowing for detailed microscopic examination of the printed structures.
