Research sheds new light on proton behavior, draws praise from science community

Consider: You've always thought that the only way to travel from northern New Jersey to New York City was over the Hudson River via the George Washington Bridge. Then one day there's a news flash: The Lincoln Tunnel through ...

Neutrons probe structure of enzyme critical to development of next-generation HIV drugs

A team led by the Department of Energy's Oak Ridge National Laboratory used neutron analysis to better understand a protein implicated in the replication of HIV, the retrovirus that causes AIDS. The enzyme, known as HIV-1 ...

Tiny tubes move into the fast lane

For the first time, Lawrence Livermore National Laboratory (LLNL) researchers have shown that carbon nanotubes as small as eight-tenths of a nanometer in diameter can transport protons faster than bulk water, by an order ...

Dancing on ice: Experiments show how protons inside ice behave

While drinking your favourite cold drink, you probably do not imagine what is going on inside each ice cube. At the Okinawa Institute of Science and Technology Graduate University (OIST), the Theory of Quantum Matter Unit, ...

Rogue rubidium leads to atomic anomaly

The behavior of a few rubidium atoms in a cloud of 40,000 hardly seems important. But a handful of the tiny particles with the wrong energy may cause a cascade of effects that could impact future quantum computers.

Mapping the nuclear pore complex: 1.5 billion years of innovation

(Âé¶¹ÒùÔº)—If asked to describe the differences between humans and frogs, a child might say that one hops and rib-its while the other walks and talks. If we ask that same child how to build a frog, they will probably need ...

First observation made of quantum-tunneling diffusion of hydrogen atoms on ice

(Âé¶¹ÒùÔº)—As long as the temperature is above absolute zero, gas molecules are always in constant random motion. They may diffuse—or spread out—through three-dimensional space or, in a process called "surface diffusion," ...

Red light goes green: Metal-free organic sensitizers portend significant advance in artificial photosynthesis

(Âé¶¹ÒùÔº)—Photosynthesis – the ubiquitous yet remarkable process by which most plants, algae, and cyanobacteria convert light energy into chemical energy – provides the atmospheric oxygen and organic compounds fundamental ...

Protons hop from one water molecule to another given suitable energy conditions

Protons, as positively charged hydrogen ions, move very rapidly in water from one water molecule to the next, which is why the conductivity of water is relatively high. The principle of proton conduction in water has been ...
