Exciting silicon nanoparticles

A method to characterize and design the optical properties of silicon nanoparticles for their use on silicon chips has been developed by A*STAR researchers in collaboration with colleagues from Russia, Israel and Australia. ...

Exceptionally strong and lightweight new metal created

A team led by researchers from the UCLA Henry Samueli School of Engineering and Applied Science has created a super-strong yet light structural metal with extremely high specific strength and modulus, or stiffness-to-weight ...

Gold 'nano-drills'

Spherical gold particles are able to 'drill' a nano-diameter tunnel in ceramic material when heated. This is an easy and attractive way to equip chips with nanopores for DNA analysis, for example. Nanotechnologists of the ...

Sunlight generates hydrogen in new porous silicon

Porous silicon manufactured in a bottom up procedure using solar energy can be used to generate hydrogen from water, according to a team of Penn State mechanical engineers, who also see applications for batteries, biosensors ...

Hot nanoparticles for cancer treatments

Nanoparticles have a great deal of potential in medicine: for diagnostics, as a vehicle for active substances or a tool to kill off tumours using heat. ETH Zurich researchers have now developed particles that are relatively ...
