How do in-situ X-ray diffraction tests work on batteries at a particle accelerator? 🤔 . . . . Hello everyone, today I would like to show you how the commissioning work of in-situ tests on batteries is carried out at the Paineira beamline, located at Centro Nacional de Pesquisa em Energia e Materiais (CNPEM)! The focus of this video was to provide a general overview of how everything unfolds to the public. I am a collaborating researcher at the Paineira beamline and responsible for this commissioning. I am available to answer any questions you may have! #BrazilianScience #SulfurBatteries #Research

This in-situ phase-contrast time-series depicts crystallization of a disordered Au cluster inside a single-walled carbon nanotube (SWCNT). The cluster shows reversible order-disorder transitions before formation of final stable ordered phase. The time-series was acquired using an image-corrected Thermo Fisher Scientific Titan 80–300 microscope operated at 80 kV and was taken from the paper mentioned in my previous post: https://lnkd.in/dtNNwPAM #monomerattachment #exergonic #rversibleorderdisordeetransition #particlecoalescence #LVEM #insituTEM #imagecorrection #electronmicroscopy

After a long period of preparation, the installation of key devices for the TWOCRYST beam test is now imminent! The picture shows colleagues from the TWOCRYST collaboration gathered in the LHC tunnel to plan the installation of an unprecedented precession crystal during the Year End Technical Stop (YETS) 2024/2025. TWOCRYST is set to operate in 2025, conducting tests where protons - essentially hydrogen nuclei - will be directed at the crystal at energies of up to several TeV, nearly at the speed of light. These tests will explore how efficiently the crystal can steer charmed baryons in a potential future experiment. These particles, containing charm quarks, live for only 1/10000 of a billionth of a second! By guiding them through silicon crystals, we aim to control their spin and uncover deeper insights into the fundamental building blocks of the universe. #CERN #LHC #ParticlePhysics #TWOCRYST #PhysicsBeyondColliders

Atomic level understanding of the processes, taking place in halide perovskites, empowers their applications in various crucial sectors, for example, in the field of #photovoltaics ☀ It is absolutely amazing that the #TEM enables this cutting-edge research! “iDPC-STEM shows great potential for imaging beam-sensitive and light-element materials, which makes it very suitable for investigating the structure-property relation of metal halide perovskite. Especially when we want to in situ observe the phase transition process of a single perovskite particle, an electron dose much lower than the threshold needs to be adopted, since the electron dose will accumulate during the continuous imaging process. In this case, ultralow-dose iDPC-STEM is important for us to record the rotation angles of octahedral units in over six images of the same area, which can be used to describe the whole phase transition process in this particle. We are confident that the iDPC-STEM can further help us to address much more issues of the material structures and their evolution in various related applications.” Prof. Boyuan Shen Learn more: https://lnkd.in/eZEx8QE3

A new article, featuring #GIWAXS experiments conducted at the #SIRIUSBeamline at Synchrotron SOLEIL, explores how surface functionalization improves perovskite solar cell performance. The study focuses on oxide-based transport layers, which are prone to defects. The authors applied a special coating to the surface of NiOx, enhancing charge transport across the perovskite hole transport layer (HTL) interface. They achieved hysteresis-free devices with a ≈13% increase in efficiency. #GIWAXS was used to monitor the growth of the perovskite film on both bare NiOx and treated NiOx surfaces Users coming from India: Indian Institute of Science (IISc), Bengaluru, India: Understanding the Heterointerfaces in Perovskite Solar Cells via Hole Selective Layer Surface Functionalization Bidisha Nath, Sushant K.

Scalable photonic sources using two-dimensional lead halide perovskite superlattices using Phelos equipment from Fluxim Ag. The authors report decoupled multi-quantum-well superlattices comprised of colloidal quantum wells of lead halide perovskites, with unprecedentedly ultrathin quantum barriers that screen interlayer interactions within the range of 6.5 Å. Crystallographic and 2D k-space spectroscopic analysis reveals that the transition dipole moment orientation of bright excitons in the superlattices is predominantly in-plane and independent of the stacking layer and quantum barrier thickness, confirming interlayer decoupling more information visit here:-https://lnkd.in/gmpddv_W #solarcells #perovskite #oled

{BI2SE3 INTERLAYER TREATMENTS AFFECTING THE Y3FE5O12 (YIG) PLATINUM SPIN SEEBECK EFFECT} In conclusion, Bi2Se3 nanoribbons provide a significant improvement in Pt/YIG spin Seebeck voltages at low surface coverages (2.5%). Spin Seebeck coefficients in the range of 0.34–0.62 μV/K for Pt/Bi2Se3/YIG are attained for our measured devices, compared to just 0.09 μV/K for Pt/YIG controls alone, for a 12 K thermal gradient and a magnetic field swept from −50 to +50 mT. SQUID and MFM measurements provide evidence that surface magnetism concentration by the Bi2Se3 nanoribbons is an important feature associated with SSE enhancement. These results provide interesting avenues for further experimentation and will hopefully stimulate theoretical debate and development in the longitudinal spin Seebeck field. To understand the surface magnetization effects in sample BSYIG1-a further, #magneticforcemicroscope (#MFM) measurements were undertaken using a commercial atomic force microscope and magnetic NanoWorld Pointprobe® MFMR #AFMprobes. More MFM Probe details: https://lnkd.in/gVEhbnd #Superconductingquantuminterferencedevice #Magneticdipolemoment #magneticfields #transitionmetals #MFMプローブ #磁性力调制显微镜
