surfaces

For example, drought prompts plants to thicken the waxy cuticle layer on leaf surfaces.

One thing they still don't do well, however, is measure or "feel" surfaces -- a purely mechanical function.

The team used electrocatalysis, a type of chemical reaction initiated by electron transfers to and from reactants on surfaces of catalysts, to convert carbon dioxide into biocompatible intermediates, such as acetate and ethanol.

The ground in November is not as cold as it would be in midwinter so some of the snow hitting the roads will probably melt, though larger accumulations could gather on colder grassy surfaces.

“We have to have a larger portion of our groundwater recharge coming from managing rainwater, in getting rid of impervious surfaces and letting it infiltrate,” Winter said.
