For a Better Contrast

Rare earth orthoferrite LnFeO3 nanoparticles for bioimaging

06-Sep-2018

Magnetic resonance imaging (MRI) has emerged as one of the most powerful clinical imaging tools because of its superb spatial resolution and soft tissue contrast, especially when using contrast agents. In the European Journal of Inorganic Chemistry, scientists have presented a new kind of ...

Deep-depletion: A new concept for MOSFETs

01-Nov-2017

Silicon has provided enormous benefits to the power electronics industry. But performance of silicon-based power electronics is nearing maximum capacity. Enter wide bandgap (WBG) semiconductors. Seen as significantly more energy-efficient, they have emerged as leading contenders in developing ...

When a porous solid retains its properties in liquid form

12-Oct-2017

Known for their exceptional porosity that enables the trapping or transport of molecules, metal-organic frameworks (MOFs) take the form of a powder, which makes them difficult to format. For the first time, an international team led by scientists from the Institut de recherche de Chimie Paris, ...

When enzymes rival platinum

05-Sep-2017

A fuel cell converts chemical energy into electrical energy via hydrogen combustion. Though it is considered to be a clean technology - because it does not emit greenhouse gases - fuel cells do use costly rare metal catalysts1, such as platinum, to oxidize hydrogen and reduce oxygen. In recent ...

Why beer overflows when a one bottle is bumped against another

24-Jan-2014

Scientists at Universidad Carlos III de Madrid (UC3M) reveal the physical phenomenon that explains beer’s rapid transformation from a liquid to a foamy state as the result of an impact. This research has applications in the area of naval engineering or in studies related to the prediction of ...

Significant step forward in biofuels quest

03-Jan-2014

Scientists at the University of York have made a significant step in the search to develop effective second generation biofuels. Researchers from the Department of Chemistry at York have discovered a family of enzymes that can degrade hard-to-digest biomass into its constituent sugars. 'First ...

Framework in place for faster market penetration of LFP

Hydro-Québec, Université de Montréal, Centre National de la Recherche Scientifique (CNRS) and Süd-Chemie agree on the issuing of sublicenses for LMP/LFP battery material

06-Jul-2011

The owners of the rights to key patents on lithium metal phosphate, including lithium iron phosphate (LMP/LFP), and related battery materials, in conjunction with Süd-Chemie AG, Munich, have established a new foundation for broad-based, global marketing of these materials. LMP/LFP is an ...

Turbulence around heat transport

07-Dec-2009

Not only in the Earth's mantle, in the atmosphere and in the outer layers of the Sun, but also in a chemical reactor, the exchange of heat may not be as effective as originally thought. There, because warm fluid rises and hence induces movement, the turbulent convection can be 100 billion times ...

Instantaneous trace gas fingerprint with laser frequency combs

Scientists at the MPQ record ultrasensitive absorption broadband spectra within tens of microseconds by combining cavity enhancement and frequency comb spectroscopy

01-Dec-2009

Trace gas spectroscopic detection has drawn much interest in recent years, as it both allows a better understanding of the molecular spectra of weak overtone transitions and in situ non-intrusive sensing of compounds at low concentration. However, recording a broadband spectrum within a very ...

Breaking the ties that bind: New hope for biomass fuels

Los Alamos researchers crack code for binding lignocellulosic biomass

24-Apr-2009

Los Alamos National Laboratory researchers have discovered a potential chink in the armor of fibers that make the cell walls of certain inedible plant materials so tough. The insight ultimately could lead to a cost-effective and energy-efficient strategy for turning biomass into alternative ...
