New synthesis strategy controls handedness in large, light-emitting molecular spirals |
|
Helicenes are a class of organic molecules consisting of benzene rings arranged in a spiral-like shape. These molecules exhibit significant circularly polarized luminescence—emission of light with left or right handedness—and ... |

Researchers compared the transcriptomic effects of free manganese oxide nanoparticles with pristine and degraded graphene-MnO? composites in A549 human lung cells after 24 hours of exposure. Free MnO? triggered much broader changes in gene expression, including pathways linked to cellular stress and apoptosis, while the graphene-bound forms produced much smaller transcriptional responses. 11/10/2026

Hierarchical Carbon Nanospheres Increase Salt Removal In Flow-Electrode Desalination
Researchers tested hierarchical hollow carbon nanospheres (HCNSs) as flow-electrode materials for capacitive deionization and compared them with commercial activated carbon and hollow mesoporous carbon nanospheres. Under the selected conditions, HCNS-based electrodes removed salt faster, with high charge efficiency and low energy consumption, and the authors attributed these results to their hollow geometry, hierarchical pore structure, low slurry viscosity, and favorable ion transport. 11/09/2026
