That's right, the electrical activity of your brain can be measured using a tool called an electroencephalogram (EEG). This electrical activity is responsible for everything from your thoughts and emotions to your movements and senses. ⚡ . . . . #nmn #BrainFacts #BrainHealth #ScienceIsAmazing #NMNBio

#Review The Feature, Performance, and Prospect of Advanced Electrodes for Electroencephalogram by Qing Liu, Liangtao Yang, Zhilin Zhang, Hui Yang, Yi Zhang and Jinglong Wu https://lnkd.in/eweFHHSs MDPI SHENZHEN INSTITUTE OF ADVANCED TECHNOLOGY CHINESE ACADEMY OF SCIENCES #EEG #advancedelectrodes #impedance #signalquality #openaccess #Abstract Recently, advanced electrodes have been developed, such as semi-dry, dry contact, dry non-contact, and microneedle array electrodes. They can overcome the issues of wet electrodes and maintain high signal quality. However, the variations in these electrodes are still unclear and not explained, and there is still confusion regarding the feasibility of electrodes for different application scenarios. In this review, the physical features and electroencephalogram (EEG) signal performances of these advanced EEG electrodes are introduced in view of the differences in contact between the skin and electrodes. Specifically, contact features, biofeatures, impedance, signal quality, and artifacts are discussed. The application scenarios and prospects of different types of EEG electrodes are also elucidated.

I'm thrilled to share that our co-authored article, "Nonlinear control of a hybrid pneumo-hydraulic mock circuit of the cardiovascular system," has been officially published in the International Journal of Robust and Nonlinear Control, a prestigious Q1 journal. In this research, we explored the dynamic testing of Ventricular Assist Devices (VAD) using Hybrid Cardiovascular Mock Circuits (HMC). By combining a variable elastance-driven numerical cardiovascular circuit with a pneumo-hydraulic physical circuit, we aimed to control the system without linearizing dynamics, overcoming the challenges of nonlinear pneumatic dynamics and noise. Special thanks and congratulations to the entire team and collaborators at YTU Physiological Control Laboratory who played a pivotal role in making this research possible. I also extend my sincere appreciation to Prof. Kamuran Kadipasaoglu for his mentorship, guidance, and for providing us with the opportunity to contribute to this significant article. 🔗 You can explore the full article here: https://lnkd.in/gRtYnk6M #CardiovascularResearch #VAD #NonlinearControl #ScientificPublication #Innovation #RNC

Tuesday publication update! 📖 In this newest publication, the #FusionAX system was used to do electrical biasing experiments using in situ electron microscopy on next-generation resistive random-access memory (RRAM). 🔍 By employing advanced electron microscopy techniques, including transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), and electron energy-loss spectroscopy (EELS), the microstructural evolution of Pt/NiO/Nb2O5 x/Pt bilayer devices could be followed. ⚡ The results clearly show that adding a polycrystalline NiO layer not only improved the electrical properties of Pt/Nb2O5 x/Pt monolayer devices but also led to a doubling of endurance and a reduction of the set voltage in Pt/NiO/Nb2O5 x/Pt bilayer devices. 🔬 Electron microscopy showed the intricate nature of the conductive filament (CF), showcasing the presence of oxygen vacancies and the formation of a funnel-shaped CF with the neck at the NiO/Nb2O5 x interface. These insights provide a unique perspective and innovative strategy for enhancing RRAM devices and exploring new applications in electronics.

I am delighted to announce the publication of our latest paper titled ”A Metamaterial-like Structure Design Using Non-Uniformly Distributed Dielectric and Conducting Strips to Boost the RF Field Distribution in 7T MRI " in Sensors MDPI, Volume 24, Issue 7, Pages 2250, 2024. This paper contributes significant insights to the field of Metamaterial in 7T MRI. The study, provides new insights into a metamaterial-based design for MRI applications. We demonstrate the advantages of a non-uniform distribution of the dielectric and conducting strips, i.e., an increase in the RF field coverage and that ability to tailor the local E-field hot spots. #Metamaterial #MRI #7T Weizmann Institute of Science MDPI #metasurface https://lnkd.in/dq_T4Q4J

🚀 Exciting News! I am thrilled to announce that our paper, "Effect of Impeller Phase on the FDA Blood Pump Velocity Field," has been published in Artificial Organs! 🩺The FDA blood pump is a benchmark cardiovascular device used to validate CFD analyses of new blood pumps. Despite its critical role, a comprehensive fluid dynamics analysis, including impeller orientations and relative velocity fields, was missing. We filled these gaps using particle image velocimetry (PIV) measurements, revealing over 30% deviations between different impeller orientations and highlighting the crucial role of turbomachinery equations in blood pump designs. 🔍Also, our study is the second validation dataset for the FDA blood pump in the literature and we as Biofluids and Cardiovascular Mechanics (BCM) Lab have become the fourth group who conducted PIV measurements for this device all around the world!

Faruk KARATAS and I overcame these hurdles with patience and weekly lab meetings. We are so grateful to our supervisor, Prof. Kerem Pekkan, for his invaluable guidance and for providing us with such excellent research opportunities and equipment. 🔬 Not finished yet! Our second study, which employs a beam splitter for the simultaneous analysis of our blood turbine and pump medical device (iATVA) for right heart failure, is currently under review.

I'm glad to announce that our scientific research paper with title: "Influence of thickness scaling on the electronic structure and optical properties of oxygen deficient BaBiO3-δ thin films grown on SrTiO3-buffered Si(001) substrate" just got published in the Journal of APL Materials. Here is a link to the article: https://lnkd.in/gRPn_PZC. In this work, the relationship between the electronic structure of BaBiO3-δ thin films as studied by X-ray photoemission spectroscopy, breathing distortion's Raman signature, and the optical conductivity by spectroscopic ellipsometry is investigated. Additionally, the effect of thickness scaling is also discussed, with an observation of the suppression of breathing distortion as well as the optical band gap for thin film below 4 nm. I take this opportunity to acknowledge my recognition to the co-authors, and everyone who contributed to this work.

🎇 DST (SERB) CRG Project 🎇 We are delighted to share that Prof. Kaushal Kumar has received a Core Research Grant (CRG) from the Science and Engineering Research Board (SERB). 🔬Project title🔬 Photo-thermal optimization of upconversion nanoparticles as a contrast enhancer for Optical Coherence Tomography (OCT) 🎯 Description🎯 This proposal aims to synthesize rare earth ions e.g. Ho3+/Yb3+, Tm3+/Nd3+/Yb3+, Er3+/Nd3+/Yb3+, etc. doped frequency upconversion emission nanoparticles (UCNPs) along with the heat generation functionality. Synthesized UCNPs will show dual functionality and hence expected to be useful for bioimaging as well as cell destruction due to heat production. In this project intensive studies will be done to optimize heat generation in particles through home home-built photo-acoustic spectrometer. It is also planned to use these UCNPs as a contrast enhancer in optical coherence tomography (OCT) imaging. #serb #CRG #iitismdhanbad #iitismphysics

I am excited to present the latest scientific work from our department of neuroradiologie at #klinikumstuttgart on the topic of flow diverter stents. Admittedly, this is a somewhat controversial topic, but I believe our publication makes a valuable contribution toward better understanding and acceptance of the method The study compares the effectiveness and safety of three types of flow diverter stents—p64 classic, p64 MW HPC, and p48 MW HPC—in the treatment of unruptured MCA bifurcation aneurysms. The findings indicate that, when considering the specific anatomical factors and careful selection of the appropriate device, flow diversion is a viable treatment option for these aneurysms, offering a balance between safety and efficacy Here is the link: Frontiers | Flow diversion for unruptured MCA bifurcation aneurysms: comparison of p64 classic, p64 MW HPC, and p48 MW HPC flow diverter stents (frontiersin.org) Alexandru Cimpoca Pablo Albiña Palmarola Hans Henkes Christina Wendl #flow diversion #MCA bifurcation aneurysms # HPC coating #SAPT
