North Carolina State University researchers have developed a microfluidic system for synthesizing perovskite quantum dots across the entire spectrum of visible light. The system drastically reduces manufacturing costs, can be tuned on demand to any colour and allows for real-time process monitoring to ensure quality control. Over the last two decades, colloidal semiconductor nanocrystals, known as quantum dots (QDs), have emerged as novel materials for applications ranging from biologic...

“I hope everyone thinks about what is happening in the world around them.”   Steven Chu was awarded the Nobel Prize in Physics for his work on lasers but today spends much of his time working on new solutions to tackle climate change. Ahead of the 2018 Nobel Week Dialogue on the topic ‘Water matters’ we spoke to Steven about his love of science and how our changing climate is shaping the water on our earth. What do you most enjoy about science? “What I enjoy about it is you’re t...

Researchers at the University of Michigan and City University of New York have recently proposed and experimentally validated a transparent, electronically tunable metasurface. This metasurface, presented in a paper published in Physical Review X, can rotate the polarization of an arbitrarily polarized incident wave without changing its axial ratio. Metasurfaces are artificial sheet materials textured at a sub-wavelength scale in order to produce tailored electromagnetic responses. In recent ...

Arrays of anchored fibers are widely used in nature and consumer products such as sensors, thermal insulators, and adhesives, among other applications. As reported in a recent issue of Science, a collaboration led by researchers from the University of Michigan and Cornell University has introduced a potentially scalable approach to synthesizing nanometer-scale polymer fiber arrays. This process offers unprecedented control over the fiber properties. Polymer nanofibers with (a) countercloc...

              At least 15 unique phases of solid nitrogen are known, including twelve molecular phases, two non-molecular phases and one amorphous state. The elusive high-temperature, high-pressure phase called ι-N2 was discovered in 2002 by a Carnegie Institution-led team of researchers but its structure was unknown until now. “Our study demonstrates that the appearance of complex structures under pressure is not limited only to ...

A team led by Nicholas Melosh, an associate professor of materials science and engineering, first began testing nanostraws about five years ago using relatively tough cell lines derived from cancers, mouse cells and other sources. Now, Melosh and colleagues have shown the technique works in human cells as well, a result that could speed up medical and biological research and could one day improve gene therapy for diseases of the eyes, immune system or cancers. "What you're seeing is a huge pu...
