Understanding the formation and evolution of ice in astrophysical environments can provide information about the physical conditions encountered in space and the chemical similarities and differences between planetary and stellar systems. At the AVS 66th International Symposium and Exhibition, Edith Fayolle, an astrochemist at NASA鈥檚 Jet Propulsion Laboratory, will talk about how scientists are trying to understand properties of ice on astrophysical bodies, such as its formation, composition and sublimation -- the process by which ice transitions directly into gas, without being in its liquid phase in between.

Nature has inspired innovative research throughout human history, and three scientists recently studied white beetles to understand the physics of light scattering. At the AVS 66th International Symposium and Exhibition, researchers will talk about their study of these scales to better understand thin 鈥渟uper-white鈥� coatings that can reject solar spectrum and radiate through transparent windows. By studying light scattering at such a small scale, they were able to calculate light scattering in the biological structures faster and more accurately.

At the AVS 66th International Symposium and Exhibition, Oct. 20-25, Daniel Gunlycke will present a study on using symmetry to reduce the effects of random quantum entanglement in quantum computing applications. When deliberate, quantum entanglement can make algorithms more powerful and efficient, but uncontrolled entanglement adds unnecessary additional complexity to quantum computing, making algorithms suboptimal and more prone to error. Gunlycke says by reducing the frequency of accidental entanglements, quantum computing can be improved.

The ruddy flakes of a rusted nail are a sure sign that an undesirable chemical reaction has occurred at the surface. Understanding how molecules and atoms behave with each other, especially at surfaces, is central to managing both desirable chemical reactions, such as catalysis, and undesirable reactions, like a nail鈥檚 corrosion. Yet the field of surface chemistry has been challenged for nearly 100 years to develop predictive theories for these reactions. Now there鈥檚 progress, thanks to some new approaches.
