Enhancing Organic Light‐Emitting Diode Performance Using Naturally Derived Diatomite: A Cost‐Effective and Eco‐Friendly Strategy

open access: yesAdvanced Optical Materials, EarlyView.
Diatomite‐based light extraction structures enable enhanced photon outcoupling through multi‐angle scattering and far‐field redistribution. By harnessing the unique scattering behavior of diatomite, this approach introduces randomly oriented scattering centers that effectively reshape internal light propagation.

The autoignition of cyclopentane and cyclohexane in a shock tube

open access: yes, 2007
Ignition delay times of cyclohexane-oxygen-argon and cyclopentane-oxygen-argon mixtures have been measured in a shock tube, the onset of ignition being detected by OH radical emission.

Mechanistic Origin of Photodegradation and Impurity Effects in Donor–Acceptor Luminescent Radicals

open access: yesAdvanced Optical Materials, EarlyView.
Purification‐dependent impurities distort the apparent optical and analytical data of TTM‐based radicals without altering their intrinsic photophysical properties. Carbazole attachment elevates the activation barrier of the photodegradation pathway, offering design principles for achieving more robust luminescent radical materials.

Distribution Coefficient Calculation in Ternary Liquid-Liquid Systems [PDF]

open access: yes, 2001
A good description of liquid-liquid equilibrium is important to design extraction separation processes. Equilibrium data are normally needed as distribution coefficients for each individual component.
