Study cracks a secret of methanol production

Study cracks a secret of methanol production

Scientists from SLAC National Accelerator Laboratory, Stanford University, and Germany have figured out a key part of the industrial process for making methanol. It’s an important step toward improving the process—and eventually realizing the goal of turning a potent greenhouse gas, carbon dioxide, into fuel.

Engineers use plasmonics to create an invisible photodetector

Engineers use plasmonics to create an invisible photodetector

A team of engineers at Stanford University and the University of Pennsylvania has for the first time used plasmonic cloaking to create a device that can see without being seen—an invisible machine that detects light. It is the first example of what the researchers describe as a new class of devices that controls the flow of light at the nanoscale to produce both optical and electronic functions.

Internal atomic structure reveals key to pollution-fighting bacteria

Internal atomic structure reveals key to pollution-fighting bacteria

Some remarkable types of bacteria have proven themselves capable of "consuming" toxic pollutants, organically diminishing environmental impact in a process called bioremediation. Enzymes within these bacteria can effectively alter the molecular structure of dangerous chemicals, but the underlying mechanisms and keys to future advances often remain unknown. Now, scientists Brookhaven National Laboratory have revealed a possible explanation for the superior function of one pollution-degrading enzyme.

Engineers tackle challenges of hypersonic flight

A multiyear collaboration among Stanford University engineering departments uses some of the world's fastest supercomputers to model the complexities of hypersonic flight. Someday, their work may lead to planes that fly at many times the speed of sound.

Graphite enters different states of matter in ultrafast experiment

Graphite enters different states of matter in ultrafast experiment

For the first time, scientists have seen an X-ray-irradiated mineral go to two different states of matter in about 40 femtoseconds. Using the Linac Coherent Light Source (LCLS) X-ray Free-Electron Laser (XFEL) at SLAC National Accelerator Laboratory at Stanford University, Stefan Hau-Riege of Lawrence Livermore National Laboratory and colleagues heated graphite to induce a transition from solid to liquid and to warm-dense plasma.

New nanostructure for batteries keeps going and going

New nanostructure for batteries keeps going and going

For more than a decade, scientists have tried to improve lithium-based batteries by replacing the graphite in one terminal with silicon, which can store 10 times more charge. But after just a few charge/discharge cycles, the silicon structure would crack and crumble, rendering the battery useless. Now a team led by materials scientist has found a solution: a cleverly designed double-walled nanostructure that lasts more than 6,000 cycles, far more than needed by electric vehicles or mobile electronics.

Support for climate change action drops

Americans' support for government action on global warming remains high but has dropped during the past two years, according to a new survey by Stanford University researchers in collaboration with Ipsos Public Affairs. Political rhetoric and cooler-than-average weather appear to have influenced the shift, but economics doesn't appear to have played a role.

Study: Clean energy scale-up needs reality check

In a post-Solyndra, budget-constrained world, the transition to a decarbonized energy system faces great hurdles. Overcoming these hurdles will require smarter and more focused policies. Two Stanford writers outline their visions in a pair of analyses.

Bejeweled: Nanotech gets boost from nanowire decorations

Bejeweled: Nanotech gets boost from nanowire decorations

Engineers at Stanford University have found a novel method for “decorating” nanowires with chains of tiny particles to increase their electrical and catalytic performance. The new technique is simpler, faster and provides greater control than earlier methods and could lead to better batteries, solar cells and catalysts.

JEOL to launch world's smallest solid-state NMR probe
JEOL to launch world's smallest solid-state NMR probe

According to JEOL Resonance, a new benchmark for resolution and benchmark will be set with its introduction next week of a new 0.75-mm solid state nuclear magnetic resonance (NMR) probe. The probe is capable of high resolution sample analysis by spinning the sample at 110 kHz, the world's fastest spinning speed for NMR.

Energy Harvesting Subsystems for Wireless Sensors

Nextreme Thermal Solutions has developed two new energy harvesting subsystems for the plumbing and HVAC industries. The subsystems are the latest additions to Nextreme's Thermobility energy harvesting platform that uses thin-film thermoelectric technology to convert available thermal energy into electric power for a variety of autonomous self-powered applications.
