Ultracompact electro-optic waveguide modulator based on a graphene-covered λ/1000 plasmonic nanogap.

Opt Express 2021 Apr;29(9):13852-13863

The extreme field confinement and electro-optic tunability of plasmons in graphene make it an ideal platform for compact waveguide modulators, with device footprints aggressively scaling orders of magnitude below the diffraction limit. The miniaturization of modulators based on graphene plasmon resonances is however inherently constrained by the plasmon wavelength, while their performance is bounded by material loss in graphene. In this report, we propose to overcome these limitations using a graphene-covered λ/1000 plasmonic nanogap waveguide that concentrates light on length scales more than an order of magnitude smaller than the graphene plasmon wavelength.

Effects of Trehalose on Lipid Membranes under Rapid Cooling using All-Atom and Coarse-Grained Molecular Simulations.

J Phys Chem B 2021 May 12. Epub 2021 May 12.

Department of Chemical and Biological Engineering, Princeton University, Princeton, New Jersey 08544, United States.

We investigate the effect of the cryopreservative α-α-trehalose on a model 1,2-dimyristoyl--glycero-3-phosphocholine (DMPC) lipid membrane undergoing cooling from 350 to 250 K using all-atom (AA) and coarse-grained (CG) molecular dynamics simulation. In the AA simulations, we find that the addition of trehalose alters the (liquid crystalline) to (ripple) phase transition, suppressing the major domain of the phase and increasing the degree of leaflet interdigitation (the minor domain) which yields a thinner membrane with a higher area per lipid. Calculation of dihedral angle distributions for the lipid tails shows a greater fraction of angles in the phase as trehalose concentration is increased, indicating that trehalose increases lipid disorder in the membrane.
