The laser beam as a "3D painter"

(Phys.org)—There are many ways to create three dimensional objects on a micrometer scale. But how can the chemical properties of a material be tuned at micrometer  precision? Scientists at the Vienna University of Technology ...

Self-charging battery both generates and stores energy

(Phys.org) -- Renewable energy technologies generally consist of two distinct processes: energy generation (using sources such as coal, solar, wind, etc.) and energy storage (such as batteries). These two processes are always ...

New way to generate terahertz radiation

(Phys.org) -- Cornell researchers have developed a new method of generating terahertz signals on an inexpensive silicon chip, offering possible applications in medical imaging, security scanning and wireless data transfer.
