Intramolecular FRET Cascades Enable Small Efficiency Roll‐Off in Solution‐Processed OLEDs

open access: yesAdvanced Optical Materials, EarlyView.
This work highlights how an intramolecular FRET design strategy in solution‐processable MR‐TADF emitters enables narrowband emission, high PLQY, and efficient exciton harvesting. The resulting hyperfluorescent solution‐processed OLEDs reach up to 20.7% EQEmax with minimal efficiency roll‐off even at 10 000 cd m−2, demonstrating strong potential for ...

Drug-induced immune thrombocytopenia: Mapping of the drug binding site to the membrane-proximal region of platelet GPIX

open access: yesPlatelets, 2019
Drug-induced Immune thrombocytopenia (DIT) is a common complication of several medications, including commonly used antibiotics. The most widely studied DIT is caused by quinine. In DIT, antibodies predominantly bind to the platelet membrane glycoprotein

Green Fuel Combustion Synthesis of CeO2 and Ag/CeO2 Nanoparticles for Photocatalytic and Antibacterial Applications

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Silver‐doped cerium oxide nanoparticles (Ag/CeO2 NPs) were synthesized using Ricinus communis seed extract as a bio‐derived fuel in a solution combustion method. The combustion reaction, carried out at 450°C with AgNO3 and (NH4)2[Ce (NO3)6] as metal precursors, produced CeO2 and Ag/CeO2 NPs.

Low‐dose cannabidiol increases plasma concentrations of amitriptyline: A clinical drug–drug interaction study

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
Abstract Aims Cannabidiol (CBD), the main non‐intoxicating compound from the cannabis plant, is regularly used by patients with chronic pain who also take analgesics. CBD has previously been shown to inhibit CYP‐mediated drug metabolism. This study aimed to characterize the potential pharmacokinetic interaction of CBD with amitriptyline and tramadol ...
