Article Synopsis
- Biological protein ion channels are crucial for controlling ionic movement in the body, and graphene's properties make it a strong alternative for practical applications.
- Research shows that nanopores (up to 50 nm) in graphene can selectively favor potassium ions over divalent cations and this selectivity can be adjusted using voltage.
- The observed ion selectivity is linked to surface nanobubbles near the nanopores, and studies suggest ions move through a thin water layer at the pore's edge, showcasing a new method for creating selective graphene membranes.
In the second of a three-part series, spectral absorption behavior of nonlinear optical (NLO) dyes incorporated into amorphous polycarbonate, comprised of a homologous series of dialkyl spacer groups extending from the midsection of the dye molecule, is characterized by UV-Vis and photothermal deflection spectroscopy. The dyes are structural analogs of the NLO dye FTC [2-(3-cyano-4-{2-[5-(2-{4-[ethyl-(2-methoxyethyl)amino]phenyl}vinyl)-3,4-diethylthiophen-2-yl]vinyl}-5,5-dimethyl-5H-furan-2-ylidene)malononitrile]. Previous Monte Carlo calculations [B.
