Lull in Mars' giant impact history

more »
From the earliest days of our solar system's history, collisions between astronomical objects have shaped the planets and changed the course of their evolution. Studying the early bombardment history of Mars, scientists have discovered a 400-million-year lull in large impacts early in Martian history.

Graphenea hires Business Development Manager for US market

more »

Graphenea is expanding its business capacities by hiring a new Business Development Manager for the US market. Our new staff member, Tom Fedolak, earned his B.S. in Biochemistry & Molecular Biology from Michigan State University in 2010 and started his career in the bio-chemical industry at Draths Corporation as a molecular biologist. He then furthered his education at Georgetown University earning his M.S. in Biotechnology in 2013. While in Washington D.C., he transitioned from the laboratory to business development by working at the investment banking firm FOCUS LLC. After graduating, he moved to Boston where he furthered his experience in business development by joining U.K. Trade & Investment as a business development associate at the British consulate and most recently working at the non-profit plasmid repository Addgene as a business development analyst.

Tom will reside at Graphenea’s office in Cambridge, MA, that the company opened in October 2014. The Cambridge office services the US market for graphene products, but also acts as a liaison point for the company’s research ties with MIT and Harvard. In addition, Graphenea’s Cambridge office houses an “Applications Laboratory” to help develop custom graphene materials, with application focus on advanced polymers, thermal interface materials, energy storage, and (bio)sensors.

About Graphenea

Graphenea, a leading graphene producer venture backed by Repsol, was established in 2010, and has since grown to be one of the world's largest providers of graphene. The company is headquartered at the nanotechnology cluster CIC nanoGune in San Sebastian, Spain and the MIT campus in Cambridge, Boston, MA. Graphenea employs 23 people and exports graphene materials to more than 600 customers in 55 countries. The company has focused on constant improvement of graphene quality, becoming a supplier customers can rely on. Graphenea employs a team of skilled laboratory staff who have brought graphene production techniques to a new level. The company produces CVD graphene wafers and graphene oxide. Graphenea partners with large multinationals to develop custom graphene materials for their applications. Its research agility and ability to keep pace with the progress of graphene science and technology has allowed Graphenea to become a core partner in the Graphene Flagship, a ten year project of the European Commission worth a billion euros. The company keeps a close relation with the world's leading scientists, regularly publishing scientific articles of the highest level and holds a strong patent portfolio.

A Split Ion Tail for Comet Lovejoy E4

more »

What's happened to Comet Lovejoy? In the pictured image, a processed composite, the comet was captured early this month after brightening unexpectedly and sporting a long and intricate ion tail. Remarkably, the typically complex effect of the Sun's wind and magnetic field here caused the middle of Comet Lovejoy's ion tail to resemble the head of a needle. Comet C/2017 E4 (Lovejoy) was discovered only last month by noted comet discoverer Terry Lovejoy. The comet reached visual magnitude 7 earlier this month, making it a good target for binoculars and long duration exposure cameras. What's happened to Comet Lovejoy (E4) since this image was taken might be considered even more remarkable -- the comet's nucleus appeared to be disintegrating and fading as it neared its closest approach to the Sun two days ago.
