Diamond Batteries That’ll Last for Thousands of Years

Nuclear energy is carbon free, which makes it an attractive and practical alternative to fossil fuels, as it doesn’t contribute to global warming. We also have the infrastructure for it already in place. It’s nuclear waste that makes fission bad for the environment. And it lasts for so long, some isotopes for thousands of years. Nuclear fuel is comprised of ceramic pellets of uranium-235 placed within metal rods. After fission takes place, two radioactive isotopes are left over: cesium-137 and strontium-90.

These each have half-lives of 30 years, meaning the radiation will be half gone by that time. Transuranic wastes, such as Plutonium-239, are also created in the process. This has a half-life of 24,000 years. These materials are highly radioactive, making them extremely dangerous to handle, even with short-term exposure.

The typical nuclear power plant creates about 2,300 tons of waste annually. 99 reactors are currently employed in the United States. That’s a lot of waste per year. The US is currently stockpiling 75,000 tons of nuclear waste. It is carefully stored and maintained. However, just like anything else it is vulnerable to natural disasters, human error, even terrorism. Storage is also costly. American taxpayers are on the hook for tens of millions of dollars.
So what can be done? Researchers at the University of Bristol in the UK have a solution. Geochemist Tom Scott and colleagues have invented a method to encapsulate nuclear waste within diamonds, which as a battery, can provide a clean energy supply lasting in some cases, thousands of years.

Team Work - Meaning and Tips for better Team Work

A single brain is not always capable of making key decisions on its own. To come up with an efficient solution, an individual requires the help and advice of others. A team is established when individuals get together on a common platform with the common goal of completing a task. To guarantee optimum compatibility, team members should ideally come from similar backgrounds and have a single aim. To provide their best, the team members must complement each other and function as a single unit in tight cooperation. "There is no I in Team Work," as the saying goes, and each member must put the needs of his team first. Personal interests must take a second seat. Any team's performance is directly proportionate to the relationship between its members and their combined efforts. What is the definition of teamwork? Teamwork is defined as the sum of each team member's efforts toward the fulfilment of the team's goal. In other words, any team's backbone is its ability t

Scientists discover a new theory / The fundamental property of light – 150 years after Maxwell

Light plays a vital role in our everyday lives and technologies based on light are all around us. So we might expect that our understanding of light is pretty settled. But scientists have just uncovered a new fundamental property of light that gives new insight into the 150-year-old classical theory of electromagnetism and which could lead to applications manipulating light at the nanoscale. It is unusual for a pure-theory physics paper to make it into the journal Science. So when one does, it’s worth a closer look. In the new study, researchers bring together one of physics' most venerable set of equations – those of James Clerk’s Maxwell’s famous theory of light – with one of the hot topics in modern solid-state physics: the quantum spin Hall effect and topological insulators . To understand what the fuss is about, let’s first consider the behaviour of electrons in the quantum spin Hall effect. Electrons possess an intrinsic spin as if they were tiny spinning-tops,
