'Sniffer plasmons' could detect a single molecule of explosives

Scientists have proposed a graphene-based sensor that can 'sniff out' a single molecule of explosives.

New material discovery allows study of elusive Weyl fermion

Researchers have discovered a new type of Weyl semimetal, a material that opens the way for further study of Weyl fermions, a type of massless elementary particle hypothesized by high-energy particle theory and potentially useful for creating high-speed electronic circuits and quantum computers.

How shaping light can change particle behavior

Scientists found that the interactions between particles trapped in light distributed along an optical microfiber, as well as the speed of particle movement were different based on the light's characteristics.

Material for polymer solar cells may lend itself to large-area processing

New research results indicate that the 'sweet spot' for mass-producing polymer solar cells - a tantalizing prospect for decades - may be far larger than dictated by the conventional wisdom.

Nanomaterial safety screening could become faster, cheaper with new laboratory test

New platform uses lab-on-a-chip technology to predict how hazardous engineered nanomaterials might be.

Spin polarization by strong field ionization

Surprisingly, a joint experimental and theoretical study shows that a chance of detaching spin-up or spin-down electron from an atom can be very different.

Wi-fi from nanocrystal-based lasers

White light from lasers demonstrates data speeds of up to 2 GB/s.
