Family of site-selective molecular optical switches.
[reaction: see text] We describe the design, synthesis, and characterization of a family of thiol-reactive optical switches for labeling proteins and other biomolecules. Site-selective introduction of photochromic probes within biomolecules is being used as part of a new approach for optical control of biomolecular interactions and activities within cells. The thiol-reactive photochromic probes...
متن کاملOPTICAL ABSORPTION IN Ce0 -V 0 EVAPORATE THIN FILMS
In this work, the optical absorption near the fundamental absorption edge of co-evaporated Ce0 -V20 films is studied. It is found that the fundamental optical absorption in these materials is sharp more like that expected for crystals. It is also found that as the V O content increases, the edge becomes less sharp and shifts towards higher wavelengths
متن کاملOptical angular-momentum flux*
We introduce the angular-momentum flux as the natural description of the angular momentum carried by light. We present four main results: (i) angular-momentum flux is the flow of angular momentum across a surface and, in conjunction with the more familiar angular-momentum density, expresses the conservation of angular momentum. (ii) The angular-momentum flux for a light beam about its axis (or ...
متن کاملOptical orbital angular momentum.
We present a brief introduction to the orbital angular momentum of light, the subject of our theme issue and, in particular, to the developments in the 13 years following the founding paper by Allen et al. (Allen et al. 1992 Phys. Rev. A 45, 8185 (doi:10.1103/PhysRevA.45.8185)). The papers by our invited authors serve to bring the field up to date and suggest where developments may take us next...
متن کاملOPTICAL ABSORPTION IN ZnSiP2
The polarised absorption coefficient of ZnSiP? near the fundamental absorption edge has been studied. Three singularities were found for E l c which are attributed to pseudodirect transitions. The absorption for El/ c is mainly due to indirect transitions. A theoretical curve was fitted to the experimental results with the aid of the relative theoretical intensities for pseudodirect transitions...
