Walking molecule now carries packages

...ne is widely used in the pulp industry for turning cellulose from wood into paper. It is also the parent substance of a large class of dyes and pigments. Its chemical formula is C14H8O2. The UCR study used a scanning tunneling microscope in Bartels's laboratory that gives a precise picture of individual mole...

Meeting the ethanol challenge: Scientists use supercomputer to target cellulose bottleneck

...e, but the human process of producing ethanol from cellulose remains slow and expensive. The central bottleneck is the sluggish rate at which the cellulose enzyme complex breaks down tightly bound cellulose into sugars, which are then fermented into ethano...

Cellulose nanocrystal research could lead to new vaccines, computer inks
