This study from  IEEE Xplore explores the engineering of non-living vesicles, also known as #biomachines, using a #syntheticbiology approach. The paper introduces a groundbreaking method for developing Frequency Dependent Network Equivalents (FDNE) using an online recursive least squares (RLS) identification algorithm in the z-domain. By modeling reduced power systems as FDNE, it offers a unique perspective on enhancing system efficiency and reliability. Furthermore, the study combines Transient Stability Analysis (TSA) and FDNE using real-time digital simulators, providing a comprehensive approach to dynamic system assessment. The proposed algorithm seamlessly integrates TSA and FDNE components, offering valuable insights into aggregating external areas for TSA and formulating FDNE using RLS identification. One of the most compelling aspects of this research is its practical application in evaluating power grid performance. The study shows that the reduced order model aligns closely with the full model through experiments on Kundur's two area test system. This enables real-time simulations for dynamic assessment of large power systems. The work opens doors to new possibilities in power system engineering and offers promising avenues for enhancing grid stability and efficiency. It will be interesting to see how these findings shape the future of #synbio and power system dynamics.

Can the world of engineering cross over into human function? YES! It sure turns out we are very electrical and there is LOTS of work going to to algo and model human function (shhhh...you cannot do it fully without the endocannabinoid system..). When you look at a cell and cell division rates and factors, it turns out you can pretty well model that electrically, or at least these fellas made a nobel stab at it. Again, LOTS of work in this area. "biofields" a useful search term. https://lnkd.in/g8iN6tte

🚀 New Breakthrough in Coacervate Microdroplet Stability! 🚀 The latest study from Advait Holkar in Samanvaya Srivastava's group reveals how comb polyelectrolyte (cPE) stabilizers enhance the stability of complex coacervate microdroplets, crucial for applications like drug delivery and bioreactors. This research was made possible by leveraging BioPACIFIC MIP's automated Living Biofoundry, which enabled high-throughput materials characterization and significantly accelerated the discoveries. 🔗 Read more about the findings: https://lnkd.in/gNPTwKtT Published in Soft Matter by the Royal Society of Chemistry California NanoSystems Institute at UCLA, Shang Gao, Kathleen Villasenor, Michael Lake #MaterialsScience #Research #Automation

Latest publication from Life Science Technology Laboratory (LiST) at the Danube Private University Austria.   The new publication “Manipulating Ion Transport Regimes in Nanomembranes via a “Pore-in-Pore” Approach Enabled by the Synergy of Metal–Organic Frameworks and Solid-State Nanochannels” by Dr. Juan Allegretto, in collaboration with the Soft Matter Laboratory in Argentina, is now available in ACS Nano. This manuscript explores the modification of Solid-State Nanochannels (SSN) with Metal-Organic Frameworks (MOFs). The confined growth of Zr-based MOF alters the ion transport regime of the system, switching from diode-like to ion-current saturation regimes based on the synthetic approach. Additionally, by considering the dependence of the charge state of the UiO-66 MOF on the protonation degree, pH changes offered a mechanism to tune the iontronic output (and selectivity) among different regimes, including anion-driven rectification, cation-driven rectification, ion current saturation, and ohmic behavior. The creation of nanofluidic membranes with different modulable transport regimes has attracted special interest in the design of integrated ionic circuits for electric signal processing, ion manipulation and logical devices, as well as in other applications related to sensing, filtration, and energy conversion.

🔋 📖 Thrilled to share another new publication by BayBatt member Francesco Ciucci et al. in Joule (IF: 39.8), a top-tier energy journal! The authors study electrochemical impedance spectroscopy (EIS) through the lens of the distribution of relaxation times, a powerful tool for simplifying EIS data analysis. EIS is a cornerstone in energy science, chemistry, and biology, but traditional methods can be complex. The article offers a comprehensive overview of the field, highlighting future opportunities and advocating for standardized, automated DRT analysis tools to empower a wider range of researchers.

BIOVIA's Materials Studio (MS) empowers scientists across industries. Our comprehensive modeling and simulation tool helps scientists predict and understand the relationships between a material’s atomic and molecular structure and its properties and behavior. A recent study on lithium nickel phosphate (LNP) highlights that incorporating Fe into LNP enhances electrochemical performance, particularly cycle stability. The researchers utilized the CASTEP module in MS to calculate ionic conductivity, binding energy and lithium intercalation potential. These calculations were crucial for elucidating the mechanism and providing a rational basis for future improvements. Learn more: https://lnkd.in/gP-dpcsV.
