Thin carbon sheets for shielding against microwaves

Carbon composites have many useful properties, with new potential uses being discovered all the time. Researchers have developed a thin sheet variety to exploit its electromagnetic properties for microwave shielding.

Combing light for tell-tale chemical fingerprints

A laser-based technique that can scan and lock on to molecular vibrational signals that are normally too complex to resolve clearly could enable production of sensors for multi-species identification in harsh environments, ...

Innovative light-delivery technique improves biosensors

There is a continuing need for practical chip-based sensors that can be used at the point of care to detect cancer and other diseases. An innovative way to inject light into tiny silicon microdisks could help meet this need ...

Detecting the shape of laser pulses

A team of researchers at the Center for Relativistic Laser Science, within the Institute for Basic Science (IBS) have developed a method to measure the shape of laser pulses in ambient air. Unlike conventional strategies, ...

Processes in the atomic microcosmos revealed

Physicists at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) have successfully generated controlled electron pulses in the attosecond range. They used optical traveling waves formed by laser pulses of varying wavelengths. ...
