TEY-STXM confirms homogeneous doping of nanoparticles for non-fullerene organic solar cells
One of the challenges in modern research on the fabrication of non-fullerene acceptor based organic solar cells is the availability of very efficient hole transport layers (HTLs). A new approach that avoids mutual solubility issues is to deposit the HTL from a suspension of doped organic nanoparticles. Surface-sensitive TEY-STXM measurements at the PolLux beamline characterised the homogeneity of the dopant in the nanoparticles and develop efficient nanoparticle HTL materials for organic solar cells.
Biffo the fish: BiFeO3 nanoplate wins the Magnetism Art Competition at JEMS 2023 in Madrid
Dr. Tim A. Butcher from the Microspectroscopy group was awarded the first prize in the "Art in Magnetism" competition of the JEMS 2023 conference with his contribution "Biffo", obtained from a ptychography image of a BiFeO3 nanoplate.
From light-years to nanometers: reconstruction of unknown oscillations in STXM
From light-years to nanometers: by repurposing an algorithm originally developed for the investigation of oscillatory dynamics in astronomical objects, scientists have been able to image non-locked dynamical processes at the nanosecond and nanometer scale.
