Nano drops explode 19th century theory

Droplets emanating from a molecular "nano-tap" would behave very differently from those from a household tap 1 million times larger—researchers at the University of Warwick have found. This is potentially crucial step for ...

Superior noise control using graphene

Noise is a dangerous worldwide environmental pollutant: at normal levels found in cities it can induce annoyance, stress and fluctuations in sleep patterns which in turn increase the risk of type-2 diabetes, arterial hypertension, ...

Transformation through light

Laser physicists have taken snapshots of how C60 carbon molecules react to extremely short pulses of intense infrared light.

Precious metal tracks nanoplastics

Tiny plastic particles measuring about 100 nanometres (millionths of a millimetre) are used in many products, for example, to encapsulate dye or aromatic substances or as additives to shampoos and cosmetics. Many of them ...

Wrinkles take the heat

Single atomic sheets of black phosphorus are attracting attention for their potential in future electronics applications. A*STAR researchers have now completed experiments at the nanoscale to unlock the secret of this material's ...

A sustainable and recyclable thermoelectric paper

Thermoelectric materials, capable of transforming heat into electricity, are very promising for converting residual heat into electrical energy, as they convert hardly usable or nearly lost thermal energy in an efficient ...

Maximizing the potential of MXenes

Amidst a surge of research over the last two decades focusing on the special properties of structures that are just an atom or two thick, called "two-dimensional" materials, researchers at Drexel University have steadily ...

Antireflection coating makes plastic invisible

Antireflection (AR) coatings on plastics have a multitude of practical applications, including glare reduction on eyeglasses, computer monitors and the display on your smart-phone when outdoors. Now, researchers at Penn State ...

Layered cocktails inspire new form of male birth control

For decades, women have shouldered most of the burden of contraception. However, long-term use of female birth control pills could increase the risk for side effects such as blood clots or breast cancer. Now, inspired by ...

Waterproof graphene electronic circuits

Water molecules distort the electrical resistance of graphene, but a team of European researchers has discovered that when this two-dimensional material is integrated with the metal of a circuit, contact resistance is not ...
