Paving the way for tunable graphene plasmonic THz amplifiers

Researchers successfully demonstrated a room-temperature coherent amplification of terahertz (THz) radiation in graphene, electrically driven by a dry cell battery.

Meta-DNA structures transform the DNA nanotechnology world

Researchers announced the creation of a new type of meta-DNA structures that will open up the fields of optoelectronics (including information storage and encryption) as well as synthetic biology.

New evidence that the quantum world is even stranger than we thought

Researchers report new experimental evidence of a collective behavior of electrons to form quasiparticles called anyons. Anyons have characteristics not seen in other subatomic particles, including exhibiting fractional charge and fractional statistics that maintain a 'memory' of their interactions with other quasiparticles by inducing quantum mechanical phase changes.

A tiny instrument to measure the faintest magnetic fields

Physicists have developed a minuscule instrument able to detect extremely faint magnetic fields. At the heart of the superconducting quantum interference device are two atomically thin layers of graphene, which the researchers combined with boron nitride.

Photorealistic nanopainting with light

By shining white light on a glass slide stippled with millions of tiny titanium dioxide pillars, researchers have reproduced with astonishing fidelity the luminous hues and subtle shadings of Girl With a Pearl Earring, Dutch artist Johannes Vermeer's masterpiece.

A nano-confinement strategy to form sub-nanometer reactors

Researchers propose a nano-confinement strategy to host multiple Fe and Cu single atoms inside the extremely narrow yet regular surface cavities of graphitic carbon nitride to form sub-nanometer reactors.

Researchers synthesize silver sulfide/reduced graphene oxide composite catalysts

The development of efficient electrocatalyst to produce molecular hydrogen from water is receiving considerable attention, in an effort to decrease our reliance on fossil fuels. Silver sulfide nanocrystals have attracted enormous interests due to its excellent properties.
