New Research Publication... 'Numerical simulation of hybrid nanofluid flow with homogeneous and heterogeneous chemical reaction across an inclined permeable cylinder/plate'

Bio-inspired self-amplifying electrical transmission - mimicking signal propagation in biological axons Using the spin crossover in LaCoO3, a group of researchers have isloated semi-stable edge of chaos [EOC] phenomon, realizing small-signal negative resistance along a metalic line without a separate amplifying component. This could potentially revolutionize electronic chips by introducing superconductivity. Link: https://lnkd.in/gqUTphcn

Happy 🙂 to share another new journal I (corresponding author) co-authored with Jian-Hsing L., 廖志成, Prof. ke-horng chen along with other colleagues in IEEE Transactions on Electron Devices (TED)! We discussed the transition behavior of the transistor at the ON–OFF transient state during Unclamped Inductive-Switching (UIS) test and compare the results based on fundamental physics of magnetism wrt. real silicon data and TCAD simulations. The test is all stressed by the pulses to emulate the various harsh environments for the transistors that involve under the automotive or power-management applications. #25thIEEEPUBLICATIONS, #TED DOI: 10.1109/TED.2024.3403949 https://lnkd.in/gKCwDXV2

Measuring the exact thermal history from the inside of materials undergoing high temperature events is almost impossible. In our latest article, just accepted in Advanced Functional Materials, we present integrable magnetic supraparticles as particulate additives that are capable of recording elapsed temperature events with customizable working range up to 1000 °C and contactless spectral magnetic readout within (milli)seconds via magnetic particle spectroscopy.

Seminar details below looking at nanoindentation measurement at extreme temperatures, both hot and cold, - from cryogenic temperatures to elevated, this ground- breaking work should not be missed on 30th May at 3.00pm BST. Do you need to know more about nanoindentation testing at extreme temperatures? In the latest in our series of free, online seminars, Dr Hannah Zhang of National Physical Laboratory (NPL) will give an overview of instrumented indentation tests on hard metals, glasses and thin coatings carried out at various temperatures - from cryogenic to elevated. Register here: https://lnkd.in/dh7FkTaD Can't make the 30th May? Please consider registering anyway, as all registrants will receive a link to enable them to view the event at a later time. hashtag#materialsresearch hashtag#coatings hashtag#nanomechanicaltesting Activate to view larger image,

Anomalous Small-Angle X-ray Scattering (ASAXS) has long been recognized for its unparalleled ability to provide precise element-specific structural insights from disordered or short-range ordered materials, covering length scales ranging from a few nanometers to hundreds of nanometers. Diverging from techniques such as TEM/STEM with EDX mapping, ASAXS boasts a distinct advantage by statistically averaging elemental structural information over bulk, enabling in-operando (in-situ) data acquisition from embedded systems. Despite its formidable potential as a structural probe, this cutting-edge technique has historically been the exclusive domain of a select group of expert researchers worldwide. Our recent bold initiatives at the ASWAXS facility within NSF's ChemMatCARS (https://lnkd.in/gNWtpjtR), Sector 15, Advanced Photon Source, USA, have democratically broadened access to this transformative technique, making it available to researchers without prior expertise. The tangible fruits of our endeavors are coming to fruition through recent groundbreaking publications in ACS Nano and AngewChem, as highlighted below. For those eager to harness the power of anomalous scattering for their research, feel free to reach out to me without hesitation. https://lnkd.in/g9gqhi7e https://lnkd.in/gdUeTabF

Great example of the untapped power of combined X-ray and neutron experiments revealing new phenomena. Brought to you by the famous Grenoble Battery Hub, ESRF ID31 and BM05 beamlines, and NEXT instrument of ILL!

Not only beautiful imagery, but a powerful example of what is possible with x-rays and neutrons when industrial partners collaborate with LSRI scientists. Similar questions of how process efficiency can be addressed can be investigated in other fields, e.g., the food system, food ingredients, fermentation etc.
