Researchers at the Department of Energy's Pacific Northwest National Laboratory believe they've identified a simpler way to generate biofuels – a one-step process to convert cellulose found in plant material and other biomass into a chemical that can serve as a precursor to make fuels and plastics.
A simpler process means scientists can provide alternatives to economists and investors who are looking to make smart decisions about biofuel production as fossil fuel resources become more limited.
On Monday, June 8, at the North American Meeting of the Catalysis Society, PNNL scientist David King will discuss recent work with copper and chromium chlorides in an ionic liquid called [EMIM]Cl. These recyclable catalyst components work more effectively in tandem to break down cellulose into glucose -- and then convert the glucose into HMF, or 5-hydroxymethylfurfural, in a one-step process.
This single-step process avoids the hurdles of current multi-step approaches, and provides for the possibility of a cost effective HMF synthesis from cellulose.

Conventional light microscopes cannot distinguish structures when they are separated by a distance smaller than, roughly, the wavelength of light. Superresolution microscopy, developed since the 1980s, lifts this limitation, using fluorescent moieties. Scientists at the Max Planck Institute for Polymer Research have now discovered that graphene nano-molecules can be used to improve this microscopy technique. These graphene nano-molecules offer a number of substantial advantages over the materials previously used, making superresolution microscopy even more versatile.
Microscopy is an important investigation method, in physics, biology, medicine, and many other sciences. However, it has one disadvantage: its resolution is...
Nanooptical traps are a promising building block for quantum technologies. Austrian and German scientists have now removed an important obstacle to their practical use. They were able to show that a special form of mechanical vibration heats trapped particles in a very short time and knocks them out of the trap.
By controlling individual atoms, quantum properties can be investigated and made usable for technological applications. For about ten years, physicists have...
An international team of scientists, including three researchers from New Jersey Institute of Technology (NJIT), has shed new light on one of the central mysteries of solar physics: how energy from the Sun is transferred to the star's upper atmosphere, heating it to 1 million degrees Fahrenheit and higher in some regions, temperatures that are vastly hotter than the Sun's surface.
With new images from NJIT's Big Bear Solar Observatory (BBSO), the researchers have revealed in groundbreaking, granular detail what appears to be a likely...

Carbon nanotubes (CNTs) are valuable for a wide variety of applications. Made of graphene sheets rolled into tubes 10,000 times smaller than a human hair, CNTs have an exceptional strength-to-mass ratio and excellent thermal and electrical properties. These features make them ideal for a range of applications, including supercapacitors, interconnects, adhesives, particle trapping and structural color.
New research reveals even more potential for CNTs: as a coating, they can both repel and hold water in place, a useful property for applications like printing,...
