Twisted Hi-Bi fiber DFB lasers with controllable output polarization [PDF]

open access: yes, 2012
We demonstrate that single polarization, hi-bi fiber DFB lasers are in general characterized by elliptical state of polarization, due to the in-built fiber birefringence axis rotation.

Polar Fluorenes and Spirobifluorenes: Fluorescence and Fluorescence Anisotropy Spectra

open access: yesThe Journal of Physical Chemistry B, 2011
An extensive spectroscopic study is presented of two asymmetrically substituted fluorene dyes and of the related spiro dimers in both liquid and glassy solvents. Essential-state models are developed to accurately reproduce linear absorption and fluorescence spectra and their complex dependence on solvent polarity.

Disentangling Bulk and Surface Contributions to Charge and Discharge Fading in High‐Voltage LiCoO2

open access: yesAdvanced Functional Materials, EarlyView.
High‐voltage operation of LiCoO2 accelerates capacity fading through bulk and surface degradation. By introducing a LiTaO3 coating to selectively suppress surface degradation, bulk and surface contributions to charge and discharge fading are decoupled.

A study of the polarization of fluorescence of ordered systems with application to ordered liquid crystals

open access: yes, 1976
The fluorescence polarization of uniaxial molecules dissolved in an ordered medium is studied. A theoretical model is developed which relates the polarization of the fluorescence emission to molecular structure, orientation of absorption and emission ...

A waveguide polarization toolset design based on mode beating [PDF]

open access: yes, 2011
A toolset of waveguide elements is examined, which can be combined to produce polarization functional devices in a single contiguous waveguide. In particular, waveguide implementations of an optical isolator and a polarization modulator are discussed ...

The anti-parasitic agent suramin and several of its analogues are inhibitors of the DNA binding protein Mcm10 [PDF]

open access: yesOpen Biology, 2019
Minichromosome maintenance protein 10 (Mcm10) is essential for DNA unwinding by the replisome during S phase. It is emerging as a promising anti-cancer target as MCM10 expression correlates with tumour progression and poor clinical outcomes. Here we used

Saturation effects in polarized fluorescence photobleaching recovery and steady state fluorescence polarization

open access: yesBiophysical Journal, 1994
The time-resolved anisotropy produced in polarized fluorescence photobleaching recovery experiments has been successfully used to measure rotational correlation times in a variety of biological systems, however the magnitudes of the reported initial anisotropies have been much lower than the theoretically predicted maximum values.

Multifunctional Neutrophil Nanovesicles Induce Remodeling of Tumor Immune Microenvironment and Synergistic Multimodal Tumor Therapy

open access: yesAdvanced Functional Materials, EarlyView.
Schematic illustration of the engineered RN@FDT for multimodal tumor therapy. a) Fabrication of FD&DOX/TFA‐loaded RGD‐NNV (RN@FDT) and the light‐triggered disassemble of RN@FDT. b) After internalized by tumor cells, RN@FDT are disintegrated under NIR‐II laser irradiation to boost PTT and induce cell apoptosis.

Hanle Detection for Optical Clocks

open access: yesThe Scientific World Journal, 2015
Considering the strong inhomogeneous spatial polarization and intensity distribution of spontaneous decay fluorescence due to the Hanle effect, we propose and demonstrate a universe Hanle detection configuration of electron-shelving method for optical ...
