A customized MOF-polymer composite for rapid gold extraction from water matrices
Wendy Lee Queen, Daniel Teav Sun, Shuliang Yang, Jun Li, Li Peng, Olga Syzgantseva
With the fast-growing accumulation of electronic waste and rising demand for rare metals, it is compelling to develop technologies that can promotionally recover targeted metals, like gold, from waste, a process referred to as urban mining. Thus, there is ...
AMER ASSOC ADVANCEMENT SCIENCE2023Control of intermetallics in the interface in directed energy deposition of titanium on stainless steel 316L
Application of a single metal or alloy is often restricted by its properties from optimal combination of performance and cost. Therefore, there is a vast need of joining dissimilar metals for various applications in biomedical, aerospace, automobile and ma ...
EPFL2023Modeling high-entropy transition metal alloys with alchemical compression
Michele Ceriotti, Guillaume André Jean Fraux, Sandip De, Nataliya Lopanitsyna
Alloys composed of several elements in roughly equimolar composition, often referred to as high-entropy alloys, have long been of interest for their thermodynamics and peculiar mechanical properties, and more recently for their potential application in cat ...
AMER PHYSICAL SOC2023Persistence of variant selection in red gold alloys
Roland Logé, Cyril Cayron, Margaux Nathalie Dominique Larcher
Recently, a new thermally activated distortion with amplification (TADA) effect has been reported in red gold alloys caused by the A1 -> L1(0) phase transformation. The macroscopic amplification is due to the persistence of variant selection nucleated unde ...
ELSEVIER SCIENCE SA2022Ultimate Limit for Optical Losses in Gold, Revealed by Quantitative Near-Field Microscopy
We report thorough measurements of surface plasmon polaritons (SPPs) running along nearly perfect air-gold interfaces formed by atomically flat surfaces of chemically synthesized gold monocrystals. By means of amplitude-and phase-resolved near-field micros ...
AMER CHEMICAL SOC2022Understanding Thermomechanical Treatments Induced by Laser Powder Bed Fusion Process
Additive Manufacturing (AM) is referred to technologies that produce directly 3D parts in a layer-by-layer fashion. Laser Powder Bed Fusion (L-PBF) is one of the most important AM processes, enabling production of very complex metallic objects from a compu ...
EPFL2021Phase transformation induced distortions in red gold alloys
Margaux Nathalie Dominique Larcher
Red gold alloys owe their warm and attractive colour to the combination of gold and copper atoms. Thanks to their good mechanical properties and resistance to corrosion, red gold alloys are used in luxury industries as well as in dentistry. Around the equi ...
EPFL2021Super adsorption performance of carboxymethyl cellulose/copper oxide-nickel oxide nanocomposite toward the removal of organic and inorganic pollutants
A novel nanocomposite bead based on polymeric matrix of carboxymethyl cellulose and copper oxide-nickel oxide nanoparticles was synthesized, characterized, and applied for adsorptive removal of inorganic and organic contaminants at trace level of part per ...
SPRINGER HEIDELBERG2021Near ambient-pressure X-ray photoelectron spectroscopy study of CO2 activation and hydrogenation on indium/copper surface
Andreas Züttel, Wen Luo, Mo Li
Indium-based catalysts exhibit excellent performance for CO2 hydrogenation to methanol, yet their nature and chemical evolution under reaction conditions are still elusive, thus hindering an understanding of their reaction mechanism. In this work, near amb ...
