A new carbon network, similar to graphene but with a far more complex microscopic structure, could lead to better electric vehicle batteries researchers have predicted. Graphene, arguably the best-known exotic form of carbon, has already been tapped as a potential game-changer in li-ion battery tech, but new manufacturing methods could eventually produce even more power-dense cells.
Graphene is basically a mesh of carbon atoms, in which tiny hexagons are created as each links to three neighbors. However researchers have theorized that other structures could be generated too, beyond this straightforward honeycomb.
That’s what a team from the University of Marburg in Germany and Aalto University in Finland have developed, once again tapping carbon atoms but coaxing them into new orientations. The so-called

Carbon occurs in different forms in nature. Apart from graphite and diamond, there are some recently discovered forms with surprising properties.

For instance, graphene, having a thickness of only one atomic layer, is the thinnest known material and its exceptional properties make it a highly exciting candidate for applications such as high-tech engineering and future electronics.

Accuracy and precision are top priorities in laboratories. Not only do accurate and precise measurements ensure reliable results, but they also improve occupational health and safety in the workplace. Pipettes play an important role in maintaining accuracy and precision in laboratories, with the tools used to aspirate, measure, transport and dispense small volumes of liquid.
So how precise is a pipette? Continue reading as we explore the accuracy of pipettes, why it matters and how to keep your tools as precise as possible.
Micropipettes
Patented by German physician Heinrich Schnitger in the 1950s, micropipettes marked a new era of accuracy for scientists. After becoming increasingly frustrated with glass pipettes while teaching at the University of Marburg, Schnitger invented a version featuring a spring-loaded piston and a removable plastic tip. The design was quickly snapped up by German-based life science company Eppendorf, which began mass prod

Activists in Azerbaijan’s nascent feminist movement warn that they face harassment from the government, alongside discrimination from the wider society.
“Everyone who is active in Azerbaijan in any field is a target of the government," said psychologist Narmin Shahmarzadeh, one of the organisers of the March 8 rally to mark International Women’s Day held in Baku this year.
