Pressure stabilization effect on the donor-acceptor polyiodide chains in tetraethylammonium bis(diiodine) triiodide - insights from Raman spectroscopy
Polyiodides present high bonding flexibility already at ambient conditions, and undergo significant pressure-induced structural deformations. Resonant Raman spectroscopy has been widely used to study I-I bonds in various polyiodides, but it carries a risk ...
Cambridge2024Biobased Composites from Eugenol- and Coumarin-Derived Methacrylic Latex and Hemp Nanocellulose: Cross-Linking via [2+2] Photocycloaddition and Barrier Properties
Yves Leterrier, Sara Dalle Vacche
A novel-biobased latex was synthesized by redox-initiated emulsion copolymerization of ethoxy dihydroeugenyl methacrylate with 5 wt % of a photosensitive methacrylate containing a coumarin group. A stable copolymer latex having 16 wt % solids content and a ...
Amer Chemical Soc2024[n]Cycloparaphenylenes as Compatible Fluorophores for Melt Electrowriting
Fluorescent probes are an indispensable tool in the realm of bioimaging technologies, providing valuable insights into the assessment of biomaterial integrity and structural properties. However, incorporating fluorophores into scaffolds made from melt elec ...
Wiley-V C H Verlag Gmbh2024Speciation of Lanthanide Metal Ion Dopants in Microcrystalline All-Inorganic Halide Perovskite CsPbCl3
David Lyndon Emsley, Dominik Józef Kubicki, Daniel Prochowicz, Amita Ummadisingu, Albert Hofstetter
Lanthanides are versatile modulators of optoelectronic properties owing to their narrow optical emission spectra across the visible and near-infrared range. Their use in metal halide perovskites (MHPs) has recently gained prominence, although their fate in ...
Amer Chemical Soc2024Investigation of room-temperature single-photon emitters in GaN-based materials and GaN/AlN quantum dots
Over the past decade, quantum photonics platforms aiming at harnessing the fundamental properties of single particles, such as quantum superposition and quantum entanglement, have flourished. In this context, single-photon emitters capable of operating at ...
EPFL2024Realization of Organocerium-Based Fullerene Molecular Materials Showing Mott Insulator-Type Behavior
Electron-rich organocerium complexes (C5Me4H)(3)Ce and [(C5Me5)(2)Ce(ortho-oxa)], with redox potentials E-1/2 = -0.82 V and E-1/2 = -0.86 V versus Fc/Fc(+), respectively, were reacted with fullerene (C-60) in different stoichiometries to obtain molecular m ...
Amer Chemical Soc2024Polydopamine-coated photoautotrophic bacteria for improving extracellular electron transfer in living photovoltaics
Ardemis Anoush Boghossian, Melania Reggente, Mohammed Mouhib, Hanxuan Wang, Charlotte Elisabeth Marie Roullier, Fabian Fischer, Patricia Brandl
Living photovoltaics are microbial electrochemical devices that use whole cell–electrode interactions to convert solar energy to electricity. The bottleneck in these technologies is the limited electron transfer between the microbe and the electrode surfac ...
2024Impact of beam-coupling impedance on the Schottky spectrum of bunched beam
Tatiana Pieloni, Nicolas Frank Mounet, Christophe Emmanuel R. Lannoy
The Schottky monitors of the Large Hadron Collider (LHC) can be used for non-invasive beam diagnostics to estimate various bunch characteristics, such as tune, chromaticity, bunch profile or synchrotron frequency distribution. However, collective effects, ...
Iop Publishing Ltd2024Absolute energy levels of liquid water from many-body perturbation theory with effective vertex corrections
Alfredo Pasquarello, Aleksei Tal, Thomas Bischoff
We demonstrate the importance of addressing the F vertex and thus going beyond the GW approximation for achieving the energy levels of liquid water in manybody perturbation theory. In particular, we consider an effective vertex function in both the polariz ...
Natl Acad Sciences2024Modeling, design and economics of PEC devices
Photo-electrochemical (PEC) devices allow for converting solar energy into chemical energy and for the production of energetically dense solar fuels. Light absorption, charge separation and transport, electrochemical reactions, and ionic transport are requ ...
