Hole Transfer Dynamics in Thin Films of Mixed‐Dimensional Quasi‐2D Perovskites

Advanced Functional Materials, EarlyView.
Charge transfer dynamics in quasi‐2D perovskite (PEA2MAn−1PbnI3n+1), grown with a distinct dimensionality gradient are investigated. Selective excitation of the n = 4 phase reveals efficient hole transfer to n = 2 and n = 3 within tens of picoseconds, while n = 1 acts as a hole‐blocking layer. These findings highlight the importance of minimizing n = 1

Double Cross‐Linked Hydrogel for Intra‐articular Injection as Modality for Macrophages Metabolic Reprogramming and Therapy of Rheumatoid Arthritis

Advanced Functional Materials, EarlyView.
A hydrogel for intra‐articular injection for the treatment of rheumatoid arthritis (RA) is formulated and comprehensively studied. After administration, the hydrogel induces a metabolic reprogramming of immunometabolism of macrophages to trigger fatty acid oxidation subsequently inducing polarization of anti‐inflammatory M2 macrophages. This results in

1D Light‐Emitting MAPbBr3 Perovskite Encapsulated in Carbon Nanotubes

Advanced Functional Materials, EarlyView.
Encapsulation of MAPbBr3 perovskite in single‐walled carbon nanotubes (SWCNTs) yields a hybrid nanomaterial with distinctive optoelectronic properties. Perovskite confinement induces a unified single‐peak photoluminescence (PL) with a reduced lifetime, while charge transfer alters the optical properties of nanotubes.

Enhancing CoFe Catalysts with V2CTX MXene‐Derived Materials for Anion Exchange Membrane Electrolyzers

Advanced Functional Materials, EarlyView.
MXene dervied CoFe composites show increased initial Oxygen Evolution Reaction (OER) activity compared to the pure CoFe and MXene in an Anion Exchange Membrane device. Vanadium vacancies in the MXene plays a role in increased OER activity and hinders Fe leaching in the AEM device over using the pure V2C MXene as a support material for the CoFe ...

Mechanical support of the heart

Anaesthesia & Intensive Care Medicine, 2009
Abstract Mechanical support of the heart can be offered to patients who are refractory to pharmacological treatment, therapy for coronary or valvular disease or resynchronization therapy. Ventricular assist devices enable end-organ perfusion in the setting of heart failure.

Mechanisms of Apoptosis in the Heart

Journal of Clinical Immunology, 2003
Apoptosis is a complex and highly regulated form of cell death, and believed to contribute to the continuous decline of ventricular function in heart failure. Apoptotic cell death is observed in a variety of cardiovascular diseases, including myocardial infarction, ischemia-reperfusion injury, end-stage heart failure, arrhythmias, and adriamycin ...
