Working with CINT — Damage from low-temperature irradiation and the subsequent degradation of materials performance pose significant challenges for the storage of radioactive materials and for peripheral components in some nuclear reactor designs. In this work, we utilize Richtmyer-Meshkov instability (RMI) testing, a relatively new technique that can be used to investigate the material strength at ultrahigh strain rates when paired with hydrodynamics simulations. https://lnkd.in/geqmHE5r

Correlative Microscopy: Is It Worth the Effort? 🤔 Discover the answer in our latest blog, where Dr Pat Trimby combines detailed #EBSD and #EDS analyses with the direct measurement of physical properties using nanoindentation mapping, applied to failure analysis in the nuclear industry. https://okt.to/1vnqd4 #CorrelativeMicroscopy #Nanoindentation

#mdpimetals 📌Newly published paper sharing: Title: Radiation Techniques for Tracking the Progress of the Hydrometallurgical Leaching Process: A Case Study of Mn and Zn by Nelson Rotich Kiprono et al. The full text of the paper can be viewed and downloaded for free at https://brnw.ch/21wLdfR Highlights: • The innovation of neutron activation analysis (NAA) has been the crucial class of inorganic trace analysis approaches with the lowest quantification and detection limits • The deuterium-tritium neutron generator is a great alternative to nuclear research reactors in NAA in hydrometallurgical studies of Mn and Zn • Mn leaching (offline) increases with dissolution time, and HCl concentration but varies with the temperature of the solution • It is feasible to track Zn leaching in real-time using NAA • The dissolution of Zn improves with an increase in reaction time, and HCl concentration but varies with the temperature of the solution • Handheld X-ray fluorescence (XRF) and total-reflection XRF are promising for offline analysis of metals • The spherical diffusion prediction model requires a lot less time to attain the Zn saturation level compared to the linear diffusion model. #Hydrometallurgical #Leaching #MetalRecycling #MetalRecovery

Prophase - The early phase The prophase can be defined as the early duration of a mitosis which involves various events that are essential for the other steps. Such events include, 1, The disassembling of the nuclear membrane or the membrane retracts back to the Endoplasmic reticulum – the structural integrity of the nuclear membrane is mainly provided by lamins. The degradation of lamins leads to the retraction of the nuclear membrane. 2, Degradation of lamins 3, Kinetochore attachment Mitosis series [2/5] Article: Neethu Krishna Diagram: Achuth B S Read the article, direct link: https://lnkd.in/g45_c8iQ #mitosis #celldivision #cellcycle #cellbiology #cells #stages #sciencecommunication #scicomm

I am thrilled to announce that our paper "Non-modal stability analysis of magneto-hydrodynamic flow in a single pipe" has been published by the Fundamental Plasma Physics journal. A complete understanding of the stability of fluid flows under varying magnetic fields is imperative for achieving control of plasma and operating fluids in the blankets of future nuclear fusion reactors.  This study investigates the influence of varying magnetic profiles on the flow regime of a generic fluid, which is representative of both thermonuclear plasma and conductive fluids. Firstly, the classic modal stability technique is employed to study asymptotical stability. Then, non-modal stability analysis is applied to study the system's response for a finite time immediately after a perturbation. If you want to know more, here is the full article. #NuclearFusion #PlasmaPhysics #Magnetohydrodynamics #NonModalStabilityAnalysis

Defence and Security Accelerator and Dstl are doing some sort of magic; if you think you can help in the latest request for Market Exploration, get involved! Jedis, Magicians, and Scientists should consider getting involved. #Innovation #science #defence

Defence and Security Accelerator is reaching out to industry and academia via a new Market Exploration to get an understanding of the levels of knowledge and skills in the areas of Nuclear Quadrupole Resonance and Electron Spin Resonance for the purpose of detecting solid and liquid explosives and drugs.    We are interested in what currently exists (or could exist with more funding) in these fields, so your input will get in front of key UK and international government stakeholders as well as helping to shape future funding.
