Dolphins, long considered the second-smartest species on the planet, recognize one another by name, possess a distinct concept of "self’ and, it turns out, have some surprisingly good ideas about techniques for keeping the hulls of maritime ships clean.
Karen L. Wooley, Ph.D., professor of chemistry at Washington University in St. Louis, has noted the shape and texture of dolphin skin and how it naturally prevents marine creatures from clinging to dolphin skin. The observation fits into her study of finding ways to mediate interactions between biological systems and synthetic materials, designing chemical "functionalities," or groups of atoms, that either promote or discourage binding between them.
In one recent example, Wooley and collaborator John-Stephen A. Taylor, Ph.D., Washington University professor of chemistry, hope to employ nanoparticles that will take advantage of naturally occurring chemical interactions to deliver therapeutic drugs directly to diseased cells. At the same time, Wooley currently is developing a group of nontoxic "antifouling" coatings that may one day inhibit marine organisms such as barnacles, tube worms and zoo spores from attaching to, say, the hulls of ships.

For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.
Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...
At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.
No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...
Scientists at Tokyo Institute of Technology (Tokyo Tech) and Tohoku University have developed high-quality GFO epitaxial films and systematically investigated their ferroelectric and ferromagnetic properties. They also demonstrated the room-temperature magnetocapacitance effects of these GFO thin films.
Multiferroic materials show magnetically driven ferroelectricity. They are attracting increasing attention because of their fascinating properties such as...
