Advanced Optical Materials, EarlyView.A simple and efficient method for determining the stability of optical vortices via Fourier transform using a conventional spherical lens is presented. The theoretical and experimental results demonstrate a practical approach to directly and unambiguously measure the magnitude and sign of the topological charge of a beam without altering an ...

Advanced Photonics Research, EarlyView.Electron acceleration using multipetawatt femtosecond lasers and subcritical density plasmas achieves a maximum charge of 245 nC, with an injection rate of up to 100 nC per picosecond. The charge variation with plasma density, initially increasing and then decreasing, arises from the competition between the injection of multiple plasma waves and laser ...

Advanced Sensor Research, EarlyView.Both singlet and triplet populations of the TADF compound 4CzIPN are quenched upon interaction with dinitrotoluene by photoinduced electron transfer. However, their quenching rate is different, with the triplet excitons being more efficiently quenched due to a combination of their longer lifetime and larger population.

Advanced Sustainable Systems, EarlyView.CsFAPbI3 perovskite diodes show superior low‐voltage rectification. Ionic liquid incorporation suppresses ion migration and enhances voltage tolerance, enabling durable performance for AC–DC conversion and other optoelectronic devices. Abstract Metal halide perovskites have gained significant attention owing to their remarkable semiconductor properties

Revealing the Character of Coordination Bonding in 2D Metal–Organic Frameworks
Advanced Science, EarlyView.Photoemission‐derived momentum maps and density functional theory calculations show the re‐appearance of frontier molecular orbital patterns at two distinct binding energies, a result of the formation of bonding and antibonding states below the Fermi edge from covalent hybridisation with the metal centres.
