Thermally Activated Delayed Fluorescence in Phase‐Separated Nanostructures

open access: yesAdvanced Functional Materials, EarlyView.
A supramolecular, phase‐separation driven strategy yields charge transfer (CT) complexes from alternating electron‐deficient pyromellitic diimide and electron‐rich 4,5‐dibromoveratrole. The resulting CT complexes self‐assemble into lamellar nanosheets with nanometer‐sized domains that exhibit thermally activated delayed fluorescence (TADF) at room ...

PO2 dependence of oxygen consumption in skeletal muscle of hypertensive and normotensive rats [PDF]

open access: yes, 2017
Human essential hypertension affects over 75 million people in the United States, and can lead to death due to its several serious health complications such as hypertension-related cardiovascular disease.

Fluorescence and phosphorescence from individual C$_{60}$ molecules excited by local electron tunneling

open access: yes, 2005
Using the highly localized current of electrons tunneling through a double barrier Scanning Tunneling Microscope (STM) junction, we excite luminescence from a selected C$_{60}$ molecule in the surface layer of fullerene nanocrystals grown on an ultrathin

Fluorescent Polymeric Nanofibers as Ratiometric Multiplexed Skin Sensors of pH and Oxygen

open access: yesAdvanced Healthcare Materials, EarlyView.
Fluorescent polymeric nanofibers and nanorods are produced as ratiometric sensors of two important physiological parameters: pH and oxygen. They operate by dual Forster resonance energy transfer from large number of energy donor dyes to limited number of two distinct energy acceptors, enabling simultaneous sensing of pH and oxygen.

Rationalizing the Unexpected Inefficiencies of 3D Porphyrin‐MOFs as Singlet Oxygen Photosensitizers Against Botrytis cinerea

open access: yesAdvanced Materials Interfaces
Porphyrin‐based MOFs (PMOFs) are known to be efficient photocatalysts and singlet oxygen (1O2) photosensitizers (PS) in solution, but their application in agriculture and food protection is practically unknown.

A mathematical model of tissue axial and radial diffusion in the microvasculature for intravascular microscopy and phosphorescence quenching data

open access: yesComputers in Biology and Medicine
This study aims to extend earlier Krogh Cylinder Models of an oxygen profile by considering axial diffusion and analytically solving Fick's Law Partial Differential Equation with novel boundary conditions via the separation of variables. We next prospectively collected a total of 20 animals, which were randomly assigned to receive either fresh or two ...

Effect of Host Anisotropy on Phosphorescent Emitter Orientation and Light Outcoupling in OLEDs

open access: yesAdvanced Optical Materials, EarlyView.
The orientation of the emissive transition dipole moment of a cage‐type Iridium complex can be tuned by the anisotropic alignment of the cohost material, which is expressed as the S$S$ parameter of the film. Thus, the external quantum efficiency of OLEDs can be further enhanced to reach values above 30%.
