Long live(d) CsPbBr3 superlattices: colloidal atomic layer deposition for structural stability
Raffaella Buonsanti, Philippe Benjamin Green, Alexander Nicolas Chen, Victoria Lapointe
Superlattice formation afforded by metal halide perovskite nanocrystals has been a phenomenon of interest due to the high structural order induced in these self-assemblies, an order that is influenced by the surface chemistry and particle morphology of the ...
Cambridge2024Mini-colons unlock tumour development outside the body
Matthias Lütolf, Luis Francisco Lorenzo Martin
In this Tools of the Trade article, Francisco Lorenzo-Mart & iacute;n and Matthias Lutolf present mini-colons as a new ex vivo cancer model that incorporates microfabrication, tissue engineering and optogenetics. ...
Nature Portfolio2024On the importance of the humidity flux for the surface mass balance in the accumulation zone of the Greenland Ice Sheet
It is highly uncertain how the humidity flux between the snow surface and the atmosphere contributes to the surface mass balance (SMB) of the interior Greenland Ice Sheet (GrIS). Due to sparse observations, evaluations of the simulated humidity flux are li ...
Gottingen2024Study of growth-induced point defects and their impact on InGaN-based optoelectronic devices
GaN exhibits a decomposition tendency for temperatures far below its melting point and common growth temperatures used in metal-organic vapour phase epitaxy (MOVPE).This characteristic is known to be a major obstacle for realising GaN bulk substrate. There ...
EPFL2024Electrochemical sensors modified with iron oxide nanoparticles/ nanocomposites for voltammetric detection of Pb (II) in water: A review
Permissible limits of Pb 2+ in drinking water are being reduced from 10 mu gL -1 to 5 mu gL -1 , which calls for rapid, and highly reliable detection techniques. Electrochemical sensors have garnered attention in detection of heavy metal ions in environmen ...
Cell Press2024Growth and Doping Mechanisms of III-V Nanostructures by Selective Area Epitaxy
Selective area epitaxy (SAE), applied to semiconductor growth, allows tailored fabrication of intricate structures at the nanoscale with enhanced properties and functionalities. In the field of nanowires (NWs), it adds scalability by enabling the fabricati ...
EPFL2024Solvent- and catalyst-free reduction of CO2 with ammonia borane
Andreas Züttel, Youngdon Ko, Liping Zhong
Ammonia borane (AB) has been extensively studied as a solid-state hydrogen storage material. On the other hand, its reactivity with CO2 is still unclear, especially in the solid state. By carefully controlling the CO2 pressure and temperature, AB efficient ...
Cambridge2024Synthesis of metal oxide-overcoated carbon materials by liquid phase ALD and their applications in catalysis
Coating nano particles and other substrates for efficiency enhancement, protection and obtaining new atomic structures is a widespread research topic in catalysis and material synthesis. Thus far, different approaches of coating, ranging from simplest to s ...
EPFL2023Methylamine Post-Deposition Treatments of Vapor-Deposited Perovskite Thin Films
While the development of methylammonium lead iodide (MAPbI(3)) perovskite for photovoltaics has grown rapidly, the growth of high-quality material from vapor processes continues to be difficult due to challenges including crystallinity control. Methylamine ...
New York2023III-V Nitride Semiconductors Deposited At Low Temperature For Photovoltaic Applications
This thesis reports on the study and use of low temperature processes for the deposition of indium gallium nitride (InGaN) thin films in order to alleviate some of the present drawbacks of its monolitic deposition on silicon for photovoltaic applications. ...
