Peptoid nanosheets at the oil-water interface Posted: 03 Sep 2014 10:33 AM PDT Researchers have developed peptoid nanosheets that form at the interface between oil and water, opening the door to increased structural complexity and chemical functionality for a broad range of applications.

Changing temperature powers sensors in hard-to-reach places Posted: 03 Sep 2014 09:17 AM PDT Researchers have taken inspiration from a centuries-old clock design and created a power harvester that uses natural fluctuations in temperature and pressure as its power source.

Grooving crystal surfaces repel water Posted: 03 Sep 2014 07:58 AM PDT Researchers have developed a porous polymer that stores and sorts organic molecules in the presence of water, which could have big implications for various industrial processes such as energy storage.

Breakthrough for carbon nanotube solar cells: Twice as efficient as current models Posted: 03 Sep 2014 07:58 AM PDT Lighter, more flexible, and cheaper than conventional solar-cell materials, carbon nanotubes (CNTs) have long shown promise for photovoltaics. But research stalled when CNTs proved to be inefficient, converting far less sunlight into power than other methods. Scientists have now developed a carbon nanotube solar cell that is twice as efficient as its predecessors.

Ultracold atoms juggle spins with exceptional symmetry Posted: 03 Sep 2014 06:19 AM PDT Scientists have succeeded in revealing a highly symmetric exchange of spins between ytterbium atoms in different electronic orbital states.

Ship ahoy! 3-D yacht walk-arounds and other innovations Posted: 03 Sep 2014 06:17 AM PDT There are new developments in the area of seafaring and navigation. Among the novelties is a 3-D configurator that makes it possible for owners to experience cruise ships and yachts in real time, down to the last detail – even before the shipbuilding begins. Researchers will additionally display a new software program for crew management, and a ship and logistics system so that inland water routes become more feasibly useable.

New synthesis method may shape future of nanostructures, clean energy Posted: 02 Sep 2014 12:12 PM PDT A team of physicists has published new nanoscience advances that they and other scientists say make possible new nanostructures and nanotechnologies with huge potential applications ranging from clean energy and quantum computing advances to new sensor development.

Can a stack of computer servers survive an earthquake? Posted: 02 Sep 2014 08:42 AM PDT In high-seismic regions, new facilities often are engineered with passive protective systems that provide overall seismic protection. But often, existing facilities are conventional fixed-base buildings in which seismic demands on sensitive equipment located within are significantly amplified. In such buildings, sensitive equipment needs to be secured from these damaging earthquake effects.
