Unlocking the secrets of salt crystal formation at the nanoscale
Credit: Chemical Science (2024). doi:10.1039/d4sc04042b In nature and technology, crystallization plays a crucial role, from the formation of snowflakes and pharmaceuticals to the creation of sophisticated batteries and desalination membranes. Despite its importance, crystallization at the nanoscale is not much understood, primarily because it is very challenging to observe the process directly at this scale. My research overcomes this hurdle…

Microscopy breaks the barriers to nanoscale chemical imaging
SIMIP enables high-resolution images rich in both chemical and spatial information. Quantum cascade lasers (QCLs) excite molecular vibrations, while spatial light modulators (SLMs) produce striped light patterns projected onto the sample. Scientific CMO (SCMOS) cameras capture modulated fluorescent signals. It is processed using Hessian SIM and sparse deconvolution algorithms to generate high-resolution chemical and structural images. Subtracting the hot image…

Water filters with nanoscale channels selectively remove stubborn “eternal chemicals”
Credit: Monash University Traditional water filters struggle to remove smaller PFAS molecules, but the new Monash designed filter changes it. Researchers at Monash University have developed water filter membranes that effectively remove small PFA molecules, overcoming the important challenges faced by traditional water filters. The researchers designed beta-cyclodextrin (βCD)-modified graphene oxide (GO-βCD) membranes using nanoscale channels that selectively retain PFA…

Twisted Edison: A nanoscale curled filament produces light waves that rotate as they travel.
The light bulb’s Edison-style filament is twisted on a microscale, similar to the strands Jun Lu holds next to the demonstration. When the length of each twist matches the wavelength of the light emitted by the filament, the light waves rotate as they travel through space. Credit: Brenda Ahearn/Michigan Engineering Bright, twisted light can be produced using technology similar to…
