Charge transfer, or the movement of electrons, can occur either within a molecule or between two molecules. Combining the two types of charge transfer is challenging. Now, scientists from Shibaura Institute of Technology, Japan, have developed a hybrid charge transfer crystal using a novel pyrazinacene molecule. This crystal is capable of reacting with naphthalene to produce a reversible color shift, from greenish-blue to red-violet. Such color-changing crystals can have various potential applications in materials science.

Creating new drugs or medical treatments are some of the great promises of quantum computing. Scientists at the University of Sydney have for the first time used a quantum computer to simulate the chemical dynamics of real compounds, a vital step towards modelling more complex molecules and designing bespoke chemicals that could lead to improved sunscreen or skin cancer treatments.

When researchers from The University of Texas at Austin went searching for microplastics in sediments pulled from the bottom of Matagorda Bay and its surrounding inlets, they didn’t find much. Most of their samples contained only tens to hundreds of microplastic particles for each kilogram of sediment. This is hundreds to thousands of times less than other bayside environments around the world.
