Phase-stable indium sulfide achieves an energy conversion efficiency of 14.3% for solar-assisted carbon dioxide reduction to formate
Michael Graetzel, Jing Gao, Jingshan Luo, Xiaoyu Zhang, Jun Li, Qixing Zhang
Tremendous efforts have been made in developing highly selective catalysts for electrochemical CO 2 conversion to formate. However, the rapid deactivation resulting from structural reconstruction and phase transition poses considerable challenges to the sy ...
Cell Press2024Data-Intensive Exploration of the Photoelectrochemical Responses of Main-Group Metal Sulfides
Materials that efficiently promote the thermodynamically uphill water-splitting reaction under solar illumination are essential for generating carbon-free ("green") hydrogen. Mapping out the combinatorial space of potential photocatalysts for this reaction ...
Amer Chemical Soc2024Plasmonically enhanced molecular junctions for investigation of atomic-scale fluctuations in self-assembled monolayers
Molecular junctions represent a fascinating frontier in the realm of nanotechnology and are one of thesmallest optoelectronic devices possible, consisting of individual molecules or a group of moleculesthat serve as the active element sandwiched between co ...
EPFL2024Nanostructure and Optical Property Tailoring of Zinc Tin Nitride Thin Films through Phenomenological Decoupling: A Pathway to Enhanced Control
Aïcha Hessler-Wyser, Johann Michler, Amit Sharma, Caroline Hain, Daniele Casari, Thomas Nelis
This work addresses the need for precise control of thin film sputtering processes to enable thin film material tailoring on the example of zinc tin nitride (ZTN) thin films deposited via microwave plasma-assisted high power reactive magnetron sputtering ( ...
Amer Chemical Soc2024Voltage-driven Reactivity of Liquid Ga and CuGa Nanoparticles for Electrocatalytic CO2 Reduction and Synthesis
The rising atmospheric level of carbon dioxide, CO2, contributes to climate change and poses urgent need to find scalable solutions both to decrease its emissions and to be able to recycle it, if the goals of Paris Agreement to limit the temperature rise a ...
EPFL2023Voltage-driven Chemical Reactions Enable the Synthesis of Tunable Liquid Ga – Metal Nanoparticles
Raffaella Buonsanti, Anna Loiudice, Pascal Alexander Schouwink, Krishna Kumar, Coline Marie Agathe Boulanger, Valery Okatenko, Alexander Nicolas Chen
Nanosized particles of liquid metals are emerging materials which hold promise for applications spanning from microelectronics to catalysis. Yet, the knowledge of their chemical reactivity is largely unknown. Here, we study the reactivity of liquid Ga and ...
2023Decarbonizing The Production of Primary Aluminium Using Renewable Resource
Aluminium is the second most widely used metal in the world, with a variety of applications ranging from transportation to food packaging and construction. While many aluminium producers target increased utilization of recycled aluminium to produce rolled ...
Orlando, FL, American Institute of Chemical Engineering2023Femtosecond laser-induced modifications and self-organization in complex glass systems
Ultrashort laser pulses, i.e., pulses emitted shorter than a picosecond, can tailor material properties by introducing permanent modifications locally in three dimensions. Remarkably, under a certain exposure condition, these modifications are accompanied ...
EPFL2023Switching losses in power devices: From dynamic on resistance to output capacitance hysteresis
Elison de Nazareth Matioli, Remco Franciscus Peter van Erp, Hongkeng Zhu, Armin Jafari, Palliyage Srilak Nirmana Perera
In this paper, we review some of the main methods to characterize on-state and off-state losses in wide-band-gap devices under switching conditions. In the off-state, we will discuss about losses related to charging and discharging the output capacitance i ...
New York2023Modulating the Reactivity of Liquid Ga Nanoparticle Inks by Modifying Their Surface Chemistry
Raffaella Buonsanti, James Richard Pankhurst, Laia Castilla Amorós, Tzu-Chin Chang Chien
Micro- and nanosized particles of liquid metals, particularly Ga-based alloys, are attracting increasing attention for applications in several fields. The surface functionalization of Ga-based nanoparticles (NPs) with organic ligands renders easily process ...
