Demonstrating a weak topological insulator in bismuth iodide

Topological insulators are one of the most exciting discoveries of the 21st century. They can be simply described as materials that conduct electricity on their surface or edge, but are insulating in their interior bulk. ...

Study offers insights on wind development costs, taxes

A new analysis of state taxation policies regarding wind energy in the West shows New Mexico is the lowest-cost state for wind farm development, followed by Montana, Colorado and Wyoming.

Do alpha particle condensates exist in oxygen nuclei?

Nuclei in their lowest energy states (ground state) are composed of neutrons and protons. Two protons and two neutrons in a nucleus can cluster together to form alpha particles. When the nucleus gets nearly enough energy ...

Life on the edge in the quantum world

Quantum physics sets the laws that dominate the universe at a small scale. The ability to harness quantum phenomena could lead to machines like quantum computers, which are predicted to perform certain calculations much faster ...

EU electricity reform calls end to coal subsidies

European Union member states and the European Parliament agreed Wednesday to reform the bloc's electricity market, including a call to end coal subsidies by 2025.

US to ease oil drilling controls protecting imperiled bird

The Trump administration moved forward Thursday with plans to ease restrictions on oil and natural gas drilling, mining and other activities that were put in place to protect an imperiled bird species across millions of acres ...

On the cusp of valleytronics

Research into harnessing two-dimensional (2-D) materials for everyday devices has had some ups and downs. However, the emerging field of valleytronics is using energy troughs to offer renewed potential.
