Artificial Spin Ice: A New Playground to Better Understand Magnetism

Apr. 27, 2015 — For the first time, nanomagnet islands or arrays were arranged into an exotic structure (called “shakti”) that does not directly relate to any known natural material. The “shakti” artificial ... read more

Metamaterials Shine Bright as New Terahertz Source

Apr. 22, 2015 — Metamaterials allow design and use of light-matter interactions at a fundamental level. An efficient terahertz emission from two-dimensional arrays of gold split-ring resonator metamaterials was ... read more

Apr. 22, 2015 — The creation of devices to control phonons -- elusive atomic vibrations that transport heat energy in solids at speeds up to the speed of sound -- has taken a step forward when researchers ... read more

Nanoparticle Drug Reverses Parkinson's-Like Symptoms in Rats

Apr. 22, 2015 — As baby boomers age, the number of people diagnosed with Parkinson's disease is expected to increase. Patients who develop this disease usually start experiencing symptoms around age 60 or ... read more

Apr. 22, 2015 — Engineers have discovered a method to increase the amount of electric charge that can be stored in graphene, a two-dimensional form of carbon. The research may provide a better understanding of how ... read more

Apr. 22, 2015 — Researchers have discovered that electron spin brings a previously unknown degree of order to the high entropy alloy nickel iron chromium cobalt -- and may play a role in giving the alloy its ... read more

Apr. 22, 2015 — Combining state-of-the-art realistic atomistic modelling and experiments, the paper describes how thermal conductivity of ultrathin silicon membranes is controlled to large extent by the structure ... read more

Apr. 21, 2015 — Proteins and lipids have been assumed to move through cell membranes as 'nano rafts'. This 'raft hypothesis' has now been disproved by scientists. "We should not think of the ... read more

Apr. 21, 2015 — A new semiconducting material that is only three atomic layers thick exhibits electronic properties beyond traditional semiconductors. Two nano-engineered configurations of the material have shown an ... read more
