Simulations show how atoms behave inside self-healing cement

Researchers at Pacific Northwest National Laboratory (PNNL) have developed a self-healing cement that could repair itself in as little as a few hours. Wellbore cement for geothermal applications has a life-span of only 30 ...

Creating atomic scale nanoribbons

Silicon crystals are the semiconductors most commonly used to make transistors, which are critical electronic components used to carry out logic operations in computing. However, as faster and more powerful processors are ...

Nanodevice, build thyself

As we continue to shrink electronic components, top-down manufacturing methods begin to approach a physical limit at the nanoscale. Rather than continue to chip away at this limit, one solution of interest involves using ...

Trapping climate pollutant methane gas in porous carbon

As talks of global warming are once again making headlines, scientists have renewed their efforts to understand how to best limit its effects. For example, sequestrating short-lived climate pollutants, such as methane and ...

Keeping hydrogen from cracking metals

Metal alloys such as steel and zirconium that are used in pipes for nuclear reactors and oil fields naturally acquire a protective oxide or sulfide layer. But hydrogen penetration can lead to their breakdown and speed up ...
