Chaitanya Narula led analysis of an ORNL biofuel-to-hydrocarbon conversion technology to explain the underlying process.

Energy-efficient reaction drives ORNL biofuel conversion technology

A new study from the Department of Energy’s Oak Ridge National Laboratory explains the mechanism behind a technology that converts bio-based ethanol into hydrocarbon blend-stocks for use as fossil fuel alternatives.
Scientists have experimented for decades with a class of catalysts known as zeolites that transform alcohols such as ethanol into higher-grade hydrocarbons. As ORNL researchers were developing a new type of zeolite-based conversion technology, they found the underlying reaction unfolds in a different manner than previously thought.
“For 40 years, everyone thought that these reactions must go first from ethanol to ethylene, and then from there it forms longer chains. We were able to show that it’s not how this occurs,” said ORNL’s Brian Davison, coauthor on the study published in Nature Scientific Reports.

BESC creates microbe that bolsters isobutanol production

OAK RIDGE, Tenn., Aug. 14, 2015 – Another barrier to commercially viable biofuels from
sources other than corn has fallen with the engineering of a microbe that improves isobutanol yields by a factor of 10.

The finding of the Department of Energy’s BioEnergy Science Center, published in the journal Metabolic Engineering, builds on results from 2011 in which researchers reported on the first genetically engineered microbe to produce isobutanol directly from cellulose.

New ORNL hybrid microscope offers unparalleled capabilities

A microscope being developed at the Department of Energy’s Oak Ridge National
Laboratory will allow scientists studying biological and synthetic materials to simultaneously observe chemical and physical properties on and beneath the surface.

The Hybrid Photonic Mode-Synthesizing Atomic Force Microscope is unique, according to principal investigator Ali Passian of ORNL’s Quantum Information System group. As a hybrid, the instrument, described in a paper published in Nature Nanotechnology, combines the disciplines of nanospectroscopy and nanomechanical microscopy.

BESC, Mascoma develop revolutionary microbe for biofuel production

Biofuels pioneer Mascoma LLC and the Department of Energy's BioEnergy Science Center
have developed a revolutionary strain of yeast that could help significantly accelerate the development of biofuels from nonfood plant matter.

The approach could provide a pathway to eventual expansion of biofuels production beyond the current output limited to ethanol derived from corn.

James Liao of UCLA elected member of the National Academy of Sciences

Dr. James (Jim) C. Liao  has been elected as a new member in the National Academy
of Sciences. 

Dr. Liao is the Ralph M. Parsons Foundation Professor of Chemical Engineering in the UCLA Henry Samueli School of Engineering and Applied Science at the University of California – Los Angeles
Dr. Liao’s science focuses on:
  • developing the biological production of the liquid fuel isobutanol while simultaneously consuming carbon dioxide.
  • developing different methods to create liquid fuels from electricity and from waste proteins; as well as identifying a more efficient way to convert sugars into fuels.
