Their quantum phase battery consists of an n-doped InAs nanowire forming the core of the battery (the pile) and Al superconducting leads as poles. It is charged by applying an external magnetic field, which then can be switched off.

Cristina Sanz-Fernández and Claudio Guarcello, also from CFM, adapted the theory to simulate the experimental findings.

The battery is being further developed and improved at CFM premises in a collaboration between the Nanophysics Lab and the Mesoscopic Physics Group. These advances could contribute to enormous advances that many say will come from the field of quantum computing.

Ebikes may indeed require less pedalling effort than regular bicycles, but most still offer little in the way of cargo capacity or protection from the elements. The CityQ is designed to provide both, along with four-wheeled stability.

Created by Norwegian company CityQ AS, the vehicle is pedalled like a bike, with a 250-watt motor augmenting the rider’s pedalling power. However, the pedals aren’t directly linked to the drivetrain. Instead, the CityQ features what is simply described as “a software-managed drivetrain – like you find in electric cars.”

We’re still waiting to hear back about what that entails, although we suspect it may be something like the setup utilized in the Mando Footloose ebike – it uses an alternator to convert the rider’s pedalling power into electricity, which is stored in a battery that powers the motor.

Scientists have figured out a cheaper, more efficient way to conduct a chemical reaction at the heart of many biological processes, which may lead to better ways to create biofuels from plants.

Scientists around the world have been trying for years to create biofuels and other bioproducts more cheaply; this study, published today in the journal Scientific Reports, suggests that it is possible to do so.

“The process of converting sugar to alcohol has to be very efficient if you want to have the end product be competitive with ,” said Venkat Gopalan, a senior author on the paper and professor of chemistry and biochemistry at The Ohio State University. “The process of how to do that is well-established, but the cost makes it not competitive, even with significant government subsidies. This new development is likely to help lower the cost.”

Understanding the dynamics of granular materials—such as sand flowing through an hourglass or salt pouring through a shaker—is a major unsolved problem in physics. A new paper describes a pattern for how record-sized “shaking” events affect the dynamics of a granular material as it moves from an excited to a relaxed state, adding to the evidence that a unifying theory underlies this behavior.

The Proceedings of the National Academy of Sciences (PNAS) published the work by Stefan Boettcher, an Emory , and Paula Gago, an expert in modeling the statistical mechanics of granular matter in the Department of Earth Science and Engineering at the Imperial College of London.

“Our work marks another small step forward to describing the behavior of granular materials in a uniform way,” says Boettcher, professor and chair of Emory’s Department of Physics.
