The weak interfacial interaction between nanofillers and matrix nanocomposites during materials engineering have caused nanofiller reinforcing effects to be far below the theoretically predicted values. In a new report now ...
A group of trees that grow fast, live long lives and reproduce slowly account for the bulk of the biomass—and carbon storage—in some tropical rainforests, a team of scientists says in a paper published this week in the ...
