Ei-ichi Negishi, Nobel-winning chemist who made ‘art in a test tube,’ dies at 85 Harrison Smith © Jonathan Nackstrand/AFP via Getty Images Japanese chemist Ei-ichi Negishi receives the 2010 Nobel Prize in chemistry from King Carl XVI Gustaf of Sweden. Ei-ichi Negishi, a Japanese chemist who won the Nobel Prize for pioneering a precise and efficient technique to build complex organic molecules, paving the way for the development of new drugs and electronic devices, died June 6 at a hospital in Indianapolis. He was 85. Dr. Negishi spent most of his career at Purdue University in Indiana, which announced his death but did not give a precise cause. He died two days after another Nobel-winning chemist, Richard Ernst, who laid the groundwork for MRI exams.
Rice Lab Uses Laser-Induced Graphene Process to Create Micron-Scale Patterns in Photoresist
A Rice University laboratory has adapted its laser-induced graphene technique to make high-resolution, micron-scale patterns of the conductive material for consumer electronics and other applications.
Laser-induced graphene (LIG), introduced in 2014 by Rice chemist James Tour, involves burning away everything that isn’t carbon from polymers or other materials, leaving the carbon atoms to reconfigure themselves into films of characteristic hexagonal graphene.
The process employs a commercial laser that “writes” graphene patterns into surfaces that to date have included wood, paper and even food.
The new iteration writes fine patterns of graphene into photoresist polymers, light-sensitive materials used in photolithography and photoengraving. Baking the film increases its carbon content, and subsequent lasing solidif
