The electronics sector is evolving at an unprecedented pace, with constant demands for higher battery performance, faster chips, greener solvents, and more. To address these challenges, innovative technology is crucial. The majority of the conventional characterization tools have significant limitations on this new field of research, leaving scientists with little to no solutions for characterization. This is where the Turbiscan comes in, offering valuable insight into the dispersion state and stability of dark slurries and nanoparticle dispersion on native samples. With Turbiscan, researchers can access critical information regarding the properties of their materials without the need for dilution. Talk to myself or the team at @Fullbrook Systems about the Turbiscan today. https://lnkd.in/eRAVT_tg #turbiscan #batteries #slurry

In our third last post from the battery & energy materials series, we would like to share the results from the “NoRu”-project, achieved through the cutting-edge SPLS®-technology (Single Particle Light Scattering).   Using the LUMiSpoc® to characterize three different battery slurries, we've made significant strides in understanding these vital materials. The SPLS® process involves hydrodynamic focusing and laser beam analysis, providing valuable insights, including the number-based particle size distribution as well as the particle concentration in the sample.   Our sample preparation, which included meticulous dilution and ultrasonic treatment, set the stage for accurate measurements. We've compared Ketjenblack EC300, XC72R, and Super C65, unveiling their distinctive characteristics through the intensity distribution histograms of the measured sideward (left) and forward (right) scattered light of the sample dispersions.   This research opens new doors in battery technology and energy materials development.   Stay tuned for the next post, where we'll reveal more exciting discoveries! 🌟🔋   #LUM #LUMGmbH #LUMiSpoc #SPLS #CarbonBlack #BatterySlurry #BatteryTech #EnergyMaterials #Innovation #Science #Battery #Energy

Cal Nano is pleased to announce a US$300,000 down payment for a cutting-edge MSP-5 Spark Plasma Sintering (SPS) machine by Germany-based Dr. Fritsch. Cal Nano will be the first organization in North America to receive this model and once operational, it is expected to be the largest SPS machine commercially available for production and R&D manufacturing services on the continent. This purchase solidifies Cal Nano's SPS leadership, enabling larger part sizes and expanding processing capacity for new customer opportunities. “We are ecstatic to announce this down payment as we build on a thesis developed over five years ago that SPS would become a more prevalent technology,” stated CEO Eric Eyerman. “This machine is expected to open new customer applications in key growth areas, such as aerospace, cleantech, renewable energy, and industrials. These opportunities were previously beyond our reach due to the part size and throughput limitations of our current machines. Overall, Cal Nano has assembled a unique offering of advanced materials manufacturing capabilities that can scale with customers from R&D projects to commercial production.” Read more: https://lnkd.in/gA5dFxue #CaliforniaNanotechnologies #CalNano #MaterialScience #EngineeringInnovation #ResearchAndDevelopment #CryogenicMilling #CalNanoInnovation #Sparkplasmasintering #Sintering

Are you interested in the aging of batteries? Then maybe the #GeoDict software solution is of interest to you. It starts from the knowledge about the geomtery of the electrodes and the properties of the individual constituents like active materials and electrolyte. And then it predicts the aging by solving all relevant equations and how local concentrations of lithium lead to mechanical stresses and damage to the electrodes.

In a fleeting moment, I was in the process of recording the FESEM images of the meticulously crafted nanofibers intended for use in a Triboelectric Nanogenerator (TENG) #ISO5#CenterforNanotechnology#IITG

Simulation of battery aging – now experimentally validated! Battery degradation is in part caused by changes in the microstructure of the electrode during battery cycling. Lithium that enters an electrode leads to expansion of the active material while charging or operating a lithium-ion battery. How much it expands is influenced by local concentrations of lithium and results in mechanical stress on both the micro and macro levels. The altered microstructure is said to ‘age’ and suffers from capacity loss and damaging effects, like lithium-plating. The costly and time-consuming experimental approach to study aging is to analyze the microstructure of the NMC cathode and graphite anode through in-operando x-ray tomography and electrochemical characterization. The GeoDict software offers a digital, time- and cost-saving alternative by simulating local stress and electrode expansion. These simulations accurately predict the impact of microscopic structural alterations on overall battery performance. GeoDict reliably simulates and designs new battery prototypes with superior lifetime and performance in a time-saving and streamlined approach. Interested?

🔬 We are thrilled to share our latest research paper on Microporous Zr‑metal‑organic frameworks based‑nanocomposites for thermoelectric applications published by Nature-Scientific Reports (Q1). Metal-Organic Frameworks (MOFs) are gaining attention for their potential in thermoelectric applications. Our latest study focused on synthesizing PANi@MOF-801 nanocomposites through in-situ polymerization of conductive polyaniline within MOF-801's porous structure. This approach significantly enhanced electrical conductivity and thermal stability, achieving a Seebeck coefficient of -141 µVK⁻¹. By adjusting the aniline ratio, we successfully modulated semiconductor properties, with n-type composites showing the best performance. These results highlight the promise of MOF-based composites in thermoelectric technology.

Check out our latest article on #AlYN/GaN heterostructures grown by #MOCVD that is now online in APL Materials! AlYN is a novel nitride semiconductor that offers advantages similar to those of #AlScN - high piezoelectric parameters, ferroelectricity and an a lattice parameter matching to GaN, which allows for the growth of strain-free heterostructures. The high spontaneous polarization of AlYN leads to high sheet charge carrier concentrations in the #2DEG of AlYN/GaN heterostructures for #HEMTs. These sheet charge carrier concentrations are below those achieved with AlScN/GaN and enable higher electron mobilities. Furthermore, Y is more abundant on earth, easier to extract and purify than Sc. Growth of AlYN by MOCVD is challenging due to the low vapour pressure of the Y precursor - but we did it! In our paper we explore 2DEG properties in dependance of Y concentration, barrier thickness and growth temperature. Many thanks to my amazing group leader Stefano Leone who is supervising my activites at Fraunhofer IAF and of course to Patrik Stranak, Lutz Kirste, Mario Prescher und Stefan Müller for the excellent and joyful collaboration!

Here is an interesting article by Isabel Streicher from Fraunhofer IAF, delving into the study of the new MOCVD-grown material AlYN for its application in GaN HEMTs. Y in AlYN stands for Yttrium, listed as element number 39 on the Periodic Table.   Isabel Streicher conducted simulations on the 2DEG densities of AlYN/GaN heterostructures using our nextnano software, and she summarised the material parameters of the innovative alloy AlYN in her article. Our nextnano database facilitates the seamless addition of new materials. It offers our customers complete flexibility by allowing the overwriting of all material parameters in the database. Additionally, it enables the importation of alloy concentration profiles from SIMS measurements and the calculation of capacitance-voltage characteristics.
