Halide Composition Controls Phase Morphology and Device Specific Performance in Perovskite Photovoltaics and Light Emitting Diodes

open access: yesAdvanced Functional Materials, EarlyView.
We demonstrate that halide composition determines phase morphology, governing distinct operating mechanisms in mixed halide perovskites. Phase segregating 75% Br compositions enhance solar cell performance, whereas intrinsically phase‐separated 95% Br compositions provide stable light emitting diodes.

High‐Efficiency Quantum Defect Generation in Carbon Nanotubes via Oxygen‐Free Photochemistry

open access: yesAdvanced Functional Materials, EarlyView.
We show that oxygen plays an important role in quantum defect formation in carbon nanotubes and identify reaction conditions to create a range of different quantum defects for photonics and biosensing. ABSTRACT Single‐walled carbon nanotubes (SWCNTs) offer potential for a wide range of applications from optoelectronic devices to biomedical diagnostics.

Stabilization of Strongly Reduced Fe(I) Single Atom Species Coordinated in a 2D Self‐Assembled Metal–Organic Network

open access: yesAdvanced Functional Materials, EarlyView.
A graphene‐supported 2D metal–organic network stabilizes highly reactive Fe(I)‐N4 single sites through Co‐induced charge redistribution. Combined experiments and theory reveal Fe(I) formation, oxygen‐driven oxidation, and O2 activation mechanisms, offering a strategy to access low‐valent iron centers relevant to catalytic and biological processes ...

High‐Performance, Air‐Stable and Eco‐Friendly Terpene‐Processed Organic Solar Cells via Solvent‐Composition‐Controlled Film Formation Kinetics

open access: yesAdvanced Functional Materials, EarlyView.
Solvent‐composition‐controlled film formation enables high‐performance (efficiency = 18.66%) and air‐stable terpene‐processed organic solar cells. An optimized eucalyptol/tetralin ratio of 50:50 (v/v) balances molecular solvation and aggregation kinetics, producing favorable nanoscale phase separation and vertical composition gradients.

Protein-ligand binding affinities from large-scale quantum mechanical simulations

open access: yes, 2012
The accurate prediction of protein-drug binding affinities is a major aim of computational drug optimisation and development. A quantitative measure of binding affinity is provided by the free energy of binding, and such calculations typically require ...
