Engineering a Stable Solid–Electrolyte Interphase through a Novel Trifluoromethyl‐Free Lithium Salt for Lithium Metal Polymer Batteries

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The motivation behind the development of the new lithium salt LiDFFSI is to combine the advantages of both LiFSI and LiDFSI salts. LiDFFSI offers high ionic conductivity and enhanced compatibility with aluminum current collectors. Additionally, it promotes the formation of a conductive SEI layer rich in LiF and LiH, which contributes to an extended ...

Integration of Sustainable Carbon Nanoparticles Into Inverted Hybrid Perovskite Solar Cells to Enhance Optoelectronic Performance

open access: yesGlobal Challenges, EarlyView.
Carbon nanoparticles (CNPs) synthesized from sustainable chemicals, that is, citric acid and L‐tryptophan, using a green synthesis method, are used as additives in methylammonium PbI3 (MAPI)‐based hybrid perovskite (HPSCs) solar cells. The use of CNPs improves the device's fill factor, giving power conversion efficiencies up to 10% in comparison to 8.2%

Impact of Beam Profile on Raman Spectroscopy Measurements

open access: yesJournal of Raman Spectroscopy, EarlyView.
Characterisation and optimisation of the laser beam profile in Raman spectroscopy is critical to ensure accuracy and reproducibility of measurements. The laser beam size and profile have a significant effect on the axial resolution, energy distribution on the sample, focal spot size and excitation volume.

A semi‐analytical Bayesian estimate retrieval algorithm for the inversion of remote‐sensing reflectance in optically deep and shallow waters

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract The inverse problem in remote sensing of aquatic environment consists in retrieving optically significant constituents (OSCs) from a spectral measurement of the remote sensing reflectance (Rrs$$ {R}_{\mathrm{rs}} $$).Optically significant constituent includes chlorophyll a concentration (Chl a$$ Chl\ a $$), a proxy of phytoplankton biomass ...
