Researchers have eliminated problematic pinholes in the top layer of next-generation solar cells in development. At the same time, they have significantly improved the lifetime of the solar cell and made it thinner.
There is an urgent demand for new antimicrobial compounds that are effective against constantly emerging drug-resistant bacteria. Two robotic chemical-synthesizing machines, named Symphony X and Overture, have joined the search. Their specialty is creating custom nanoscale structures that mimic nature's proven designs.
Physicists have painted an in-depth portrait of charge ordering - an electron self-organization regime in high-temperature superconductors that may be intrinsically intertwined with superconductivity itself.
Researchers show how graphene oxide suspended in water biodegrades in a reaction catalysed by a human enzyme, with the effectiveness of the breakdown dependent on the colloidal stability of the suspension. The study should guide the development of graphene-based biomedical applications.
A new protocol for estimating unknown optical processes, called unitary operations, with precision enhanced by the unique properties of quantum mechanics has been demonstrated by scientists and engineers. The work could lead to both dramatically better sensors for medical research and new approaches to benchmark the performance of ultra-powerful quantum computers.
You're probably familiar with the role of DNA as the blueprint for making every protein on the planet and passing genetic information from one generation to the next. But researchers have shown that the twisted ladder molecule made of complementary matching strands can also perform a number of decidedly non-biological construction jobs: serving as a scaffold and programmable 'glue' for linking up nanoparticles.
