Computers are getting faster and increasingly powerful. However, at the same time computing requires noticeably more energy, which is almost completely converted to wasted heat. This is not only harmful to the environment, but also limits further miniaturization of electronic components and increase of clock rates.

But to fully understand how the active ingredients will behave once inside the body, scientists need to know their exact atomic-level structure. For instance, the way molecules are arranged inside a crystal has a direct impact on a compound's properties, such as its solubility. Researchers are therefore working hard to develop technologies that can easily identify the exact crystal structures of microcrystalline powders. https://www.laboratory-journal.com/news/scientific-news/ai-and-nmr-spectroscopy-determine-atoms-configuration-record-time Tue, 30 Oct 2018 13:00:00 +0000 Crystals that Clean Natural Gas https://www.laboratory-journal.com/news/scientific-news/crystals-clean-natural-gas Removing the troublesome impurities of hydrogen sulfide (H2S) and carbon dioxide (CO2) from natural gas could become simpler and more effective using a metal-organic framework (MOF) developed at KAUST. https://www.laboratory-journal.com/news/scientific-news/crystals-clean-natural-gas Tue, 30 Oct 2018 12:28:00 +0000
