The free electron laser is the next step in the development of equipment to help us see the structure of materials. Nino Čutić at MAX-lab in Lund, Sweden, has done a PhD in further improving the test free electron laser at the laboratory.
New research into drag reduction has the potential to help industries such shipping to reduce energy use and carbon emissions.
(PhysOrg.com) -- When it comes to atomic clocks, every second counts. In fact, according to Marianna Safronova, every quintillionth of a second counts.
(PhysOrg.com) -- There's a lot we don't know about the atomic nucleus, even though it was discovered a century ago this year.
A quantum computer is a device -- still largely theoretical -- that could perform some types of calculations much more rapidly than classical computers. While a bit in a classical computer can represent either 0 or 1, a quantum bit, or qubit, can be in "superposition," representing 0 and 1 at the same time. In experiments, however, keeping qubits in superposition long enough to do anything useful with them has proven very hard.
Quantum mechanics is famous for saying that a tree falling in a forest when there's no one there doesn't make a sound. Quantum mechanics also says that if anyone is listening, it interferes with and changes the tree. And so the famous paradox: how can we know reality if we cannot measure it without distorting it?
Chemistry news
Scientists from the Florida campus of The Scripps Research Institute have uncovered a potentially important new therapeutic target that could prevent stress-related cell death, a characteristic of neurodegenerative diseases such as Parkinson's, as well as heart attack and stroke.
(PhysOrg.com) -- University of Sydney scientists have discovered a startling new mechanism where sunlight can rearrange the atoms of molecules to form new chemical substances.
