'Nano stitches' enable lighter and tougher composite materials

To save on fuel and reduce aircraft emissions, engineers are looking to build lighter, stronger airplanes out of advanced composites. These engineered materials are made from high-performance fibers that are embedded in polymer ...

How phytochemical diversity affects plant adaptation to stress

Phytochemical diversity plays a critical role in determining plant adaptation and fitness, as well as ecosystem functions and services. However, phytochemicals and their ecological adaptations have long been ignored. Fine ...

Officials sued over farm chemicals near Latino schools

For Nelly Vaquera-Boggs, the plastic tarps that cover strawberry fields in Monterey County, California, when they are being fumigated with toxic chemicals offer little comfort—especially when those fields are close to schools.

New strategy for assessing the applicability of reactions

Chemists often develop and optimize new chemical reactions using so-called model systems, i.e., simple, easily accessible substrates. They then use up to around 100 other substrates as examples to show that the reaction works. ...

Novel UV broadband spectrometer improves air pollutant analysis

Sunlight has a major influence on chemical processes. Its high-energy UV radiation in particular is strongly absorbed by all materials and triggers photochemical reactions of the substances present in the air. A well-known ...
