Scientists Trap and Arrange Nanoparticles to Mimic Crystalline Structure of Diamond

Using bundled strands of DNA to build Tinkertoy-like tetrahedral cages, scientists at the U.S. Department of Energy's Brookhaven National Laboratory have devised a way to trap and arrange nanoparticles in a way that mimics the crystalline structure of diamond. The achievement of this complex yet elegant arrangement, as described in a paper published February 5, 2016, in Science, may open a path to new materials that take advantage of the optical and mechanical properties of this crystalline structure for applications such as optical transistors, color-changing materials, and lightweight yet tough materials.

Nanowires Made from Multiple Metal Oxides Enable Efficient Solar Energy Storage

Nanowires Made from Multiple Metal Oxides Enable Efficient Solar Energy Storage

By 2020, California aims to use 33% of energy from renewable sources. With the deadline nearing, researchers from all over the state are trying to identify new variable options. Solar energy is an attractive source, but it has to be converted into a storable form for widespread adoption. In a new study published in ACS Central Science, researchers have described the development of nanowires from multiple metal oxides that could address the problem.

Breakthrough Technique to Create Cubic Boron Nitride at Ambient Temperature and Air Pressure

A team of researchers from North Carolina State University have determined a new phase of boron nitride (Q-BN), which plays a vital role in both electronic displays and manufacturing tools. The team have come up with a new method for forming cubic boron nitride (c-BN) at ambient air pressure and temperatures. This method is used for a wide range of application, such as the develop,emt modern power grid technologies.

Nanostructured Membranes Could Help Stop Growth of Dendrites in Lithium Batteries

Nanostructured Membranes Could Help Stop Growth of Dendrites in Lithium Batteries

Rechargeable lithium metal batteries have been known for four decades to offer energy storage capabilities far superior to today’s workhorse lithium-ion technology that powers our smartphones and laptops. But these batteries are not in common use today because, when recharged, they spontaneously grow treelike bumps called dendrites on the surface of the negative electrode.
