Isomerization of all-trans-retinol to cis-retinols in bovine retinal pigment epithelial cells: dependence on the specificity of retinoid-binding proteins.
In the retinal rod and cone photoreceptors, light photoactivates rhodopsin or cone visual pigments by converting 11-cis-retinal to all-trans-retinal, the process that ultimately results in… Expand
The two-pathway model for the catch-slip transition in biological adhesion.

Some recently studied biological noncovalent bonds have shown increased lifetime when stretched by mechanical force. In each case these counterintuitive "catch-bonds" have transitioned into ordinary… Expand
Guest-Host Cooperativity in Organic Materials Greatly Enhances the Nonlinear Optical Response
Some of the most highly active organic electro-optic (EO) materials developed recently rely on the combination of an EO-active (chromophore-containing) host material (dendrimer or side-chain polymer)… Expand
Quantized Hamilton Dynamics
- O. Prezhdo
- 31 July 2006
The paper describes the quantized Hamilton dynamics (QHD) approach that extends classical Hamiltonian dynamics and captures quantum effects, such as zero point energy, tunneling, decoherence,… Expand
Ab initio nonadiabatic molecular dynamics of the ultrafast electron injection across the alizarin-TiO2 interface.

- 4 May 2005
The observed 6-fs photoinduced electron transfer (ET) from the alizarin chromophore into the TiO2 surface is investigated by ab initio nonadiabatic (NA) molecular dynamics in real time and at the… Expand

- 27 August 2012
Colloidal CdS quantum dots (QDs) were synthesized with tunable surface composition. Surface stoichiometry was controlled by applying reactive secondary phosphine sulfide precursors in a… Expand
Detection of nucleic acids with graphene nanopores: ab initio characterization of a novel sequencing device.
We report an ab initio density functional theory study of the interaction of four nucleobases, cytosine, thymine, adenine, and guanine, with a novel graphene nanopore device for detecting the base… Expand
Scanning tunneling microscopy of DNA-wrapped carbon nanotubes.
We employ scanning tunneling microscopy (STM) to reveal the structure of DNA-carbon nanotube complexes with unprecedented spatial resolution and compare our experimental results to molecular dynamics… Expand
Quantized Hamilton dynamics for a general potential
The quantization of Hamilton dynamics (QHD) [J. Chem. Phys. 113, 6557 (2000)] that efficiently generalizes classical mechanics to include quantum tunneling and zero-point energy effects is extended… Expand
Theoretical studies of photoinduced electron transfer in dye-sensitized TiO2.
This review describes recent research into the properties of the chromophore-TiO2 interface that forms the basis for photoinduced charge separation in dye-sensitized semiconductor solar cells. It… Expand
