Aging star's weight loss secret revealed

more »
A team of astronomers has captured the most detailed images ever of the hypergiant star VY Canis Majoris. These observations show how the unexpectedly large size of the particles of dust surrounding the star enable it to lose an enormous amount of mass as it begins to die. This process, understood now for the first time, is necessary to prepare such gigantic stars to meet explosive demises as supernovae.

Comet fragments best explanation of mysterious dimming star

more »
Astronomers have responded to the buzz about a mysterious dimming star by studying data from NASA's Spitzer Space Telescope. They conclude the dimming was probably caused by a family of comets passing in front of the star.

Graphene & 2D Materials USA

more »

Graphene & 2D Materials USA, a successor of the LIVE! series of conferences, held its sixth meeting last week in Santa Clara, CA. This event is the most commercially-focused conference and exhibition on graphene and other 2D materials. Graphene and 2D Materials is unique as it is co-located with other highly synergetic end user industries such as printed electronics, wearable technologies, electric vehicles, and 3D printing.

Graphenea CEO Jesus de la Fuente gave a lecture on the “The road to commercialization of graphene nanomaterials”, presenting the current market situation followed by market forecasts and comparisons. Jesus highlighted regulatory issues, safety regulations, quality assurance and vertical industries compliance as the main challenges toward commercialization of graphene materials.

Jesus spoke at “Graphene Applications and Market Progress”, one of several topical sections which included graphene production, dispersion, and specific application related sections like “batteries and supercapacitors”.

The Graphene & 2D Materials meeting was held alongside end user industry meetings “3D Printing”, “Energy Harvesting & Storage”, “Internet of Things”, “Printed Electronics”, “Electric Vehicles”, “Wearable”, and “Sensors”.

“We are very satisfied with the event”, proclaimed Jesus de la Fuente. “We have been attending the IDTechEx Graphene Show in the US and Europe for several years. It is a very well organized event from the business perspective. At this event you have the opportunity to learn the state of the industry through presentations and the chance to meet relevant players in the industry at the booth floor. Always interesting to mix graphene with other industries like printed electronics, supercapacitors... many opportunities arises within this format.”

Graphenea exhibited a stand, showcasing our graphene product line, focused on large area CVD graphene films and graphene oxide, commonly used with other materials in composite applications.

Make mine a double-shot, zero-G espresso

Last year Italy sent an espresso machine up to the ISS, and this inspired a team of researchers to study the related strange fluids phenomena in low gravity, such as espresso crema formation and containment of potentially hazardous drinks within a spacecraft. To do this, the researchers designed a cup that exploits surface tension as opposed to gravity.
