Boosting Zinc Hybrid Supercapacitor Performance via Thiol Functionalization of Graphene-Based Cathodes
Zinc hybrid supercapacitors (Zn-HSCs) hold immense potential toward the next-generation energy storage systems, effectively spanning the divide between conventional lithium-ion batteries (LIBs) and supercapacitors. Unfortunately, the energy density of most of Zn-HSCs has not yet rivalled the levels observed in LIBs. The electrochemical performance of aqueous Zn-HSCs can be enhanced through the chemical functionalization of… Read More

Square ice Coulomb phase as a percolated vertex lattice
The square ice is a canonical example of a Coulomb phase in two dimensions: Its ground state is extensively degenerate and satisfies a local constraint on the spin arrangement (the so-called ice rule). In this paper, we use a loop flip algorithm to explore the properties of this ground state that we analyze not in… Read More

In Operando Study of Charge Modulation in MoS2 Transistors by Excitonic Reflection Microscopy
Monolayers of transition metal dichalcogenides (2D TMDs) experience strong modulation of their optical properties when the charge density is varied. Indeed, the transition from carriers composed mostly of excitons at low electron density to a situation in which trions dominate at high density is accompanied by a significant evolution of both the refractive index and… Read More

Instability of Cobalt-Substituted Polyoxometalates during the Oxygen Evolution Reaction: An Operando X-ray Absorption Spectroscopy Study
Complexes of cobalt(II) stabilized by lacunary polyoxometalates (CoPOMs) are highly discussed water oxidation catalysts (WOC). While their activity and stability in the oxygen evolution reaction (OER) have been widely explored, there is still no consensus between those claiming that CoPOMs are active and stable OER catalysts and those suggesting that they rather act as precatalysts,… Read More

Electronic Properties of Electroactive Ferrocenyl-Functionalized MoS2
The attachment of redox-active molecules to transition metal dichalcogenides, such as MoS2, constitutes a promising approach for designing electrochemically switchable devices through the control of the material’s charge/spin transport properties by the redox state of the grafted molecule and thus the applied electrical potential. In this work, defective plasma-treated MoS2 is functionalized by a ferrocene… Read More

Molecular Junctions for Terahertz Switches and Detectors
Molecular electronics targets tiny devices exploiting the electronic properties of the molecular orbitals, which can be tailored and controlled by the chemical structure and configuration of the molecules. Many functional devices have been experimentally demonstrated; however, these devices were operated in the low-frequency domain (mainly dc to MHz). This represents a serious limitation for electronic… Read More

Covalent shaping of polyoxometalate molecular films onto ITO electrodes for charge trapping induced resistive switching
As nano-sized molecular oxides, polyoxometalates (POMs) hold great promise in non-volatile memory materials based on redox-active molecules. Materials processed from solution, by drop-casting, by embedding POMs in polymers, or using layer-by-layer deposition techniques have thus been reported and successfully investigated. Almost all of these examples are electrostatically assembled materials. We herein propose an original route… Read More
