Scientists develop invisible anti-counterfeit labels

Scientists have proposed new labels that are not so easy to decipher. They are made from semiconductor materials with the help of lasers.

Twisting, flexible crystals key to solar energy production

Researchers show how shapes and movements of halide perovskites create desirable renewable energy properties.

Solving the puzzle of polymers binding to ice for cryopreservation

Cryoprotectants are crucial when freezing biological material to lessen the cellular damage involved with the formation of ice.

Practical nanozymes discovered to fight antimicrobial resistance

Nanozymes, a group of inorganic catalysis-efficient particles, have been proposed as promising antimicrobials against bacteria. They are efficient in killing bacteria, thanks to their production of reactive oxygen species (ROS).

An international standard for industry to verify 'graphene' products

The importance of international standards for the graphene community.

New on-demand drug delivery system uses light irradiation instead of injections

A new concept of on-demand drug delivery system has emerged in which the drugs are automatically released from in vivo medical devices simply by shining light on the skin.

Voltage from the parquet

Researchers have made wood compressible and turned it into a micro-generator. When it is loaded, an electrical voltage is generated. In this way, the wood can serve as a bio-sensor - or generate usable energy.
