Electrochemical Impedance Spectroscopy (EIS) is a non-destructive, rapid, and efficient electrochemical testing method. It separates the processes involved in electrochemical reactions in the frequency domain based on the speed of the electrochemical system’s response to the excitation signal. The analysis of EIS is a complex task. A commonly used method is the equivalent circuit model, … Read more
To ask which technology in electrochemical testing is the most hair-pulling, I would say it’s EIS (Electrochemical Impedance Spectroscopy), and I think hardly anyone would disagree. There is “poetry” to prove: Measuring impedance is tough, Equivalent circuits are hard to guess; If you ask if performance improves? We’re happy if the arc shrinks! Although the … Read more
First Author: Roby Soni Corresponding Authors: Thomas S. Miller, Alexander J.E. Rettie, Affiliation: University College London, UK It is well known that Electrochemical Impedance Spectroscopy (EIS) has been widely used for battery analysis due to its simplicity and non-destructive nature. However, the data provided is generally a unified representation of all electrochemical processes within the … Read more
With the continuous advancement of medical technology, left atrial appendage closure (LAAC) has become increasingly widespread in clinical applications, bringing hope to many patients with atrial fibrillation. Antithrombotic therapy runs through the entire process of LAAC and is one of the core issues of LAAC. However, there is currently no consensus on how to formulate … Read more
On October 13, 2021, a prospective, non-randomized study published in JACC Intervention indicated that after successful left atrial appendage closure (LAAC) using the WATCHMAN device (Boston Scientific), an anticoagulation strategy centered on half-dose direct oral anticoagulants (DOAC) might improve overall surgical outcomes and reduce the occurrence of device-related thrombosis (DRT) compared to standard anticoagulation therapy … Read more
In the fields of cardiac pacing, electrophysiology, coronary intervention, traditional structural heart disease, or new structural heart disease interventions, there is a risk of device-related thrombosis (DRT), and the left atrial appendage closure (LAAC) is no exception. As one of the postoperative complications, DRT remains a key focus during postoperative follow-ups. Recently, Professor Zeng Jie … Read more
The effect of cognitive load on Detection-Response Task (DRT) performance during day- and night-time driving: A driving simulator study with young and older drivers The effect of cognitive load on detection—response task (DRT) performance during day and night driving: A driving simulator study with young and older drivers Author:Öztürk, İ., Merat, N., Rowe, R., & … Read more
Left Atrial Appendage Occlusion (LAAO) surgery is an effective alternative treatment to long-term oral anticoagulants (OAC), aimed at preventing thromboembolic events associated with non-valvular atrial fibrillation. The occurrence of device-related thrombosis (DRT) after LAAO has been a long-standing concern for both clinicians and patients, making it an important observation during postoperative follow-up. Recently, the Journal … Read more
01 Research Background To break the limitations of mechanism research and material design, it is necessary to have a comprehensive understanding of the lithium-ion dynamics in batteries. Analyzing the time scale information in batteries, such as ion conduction, charge transfer, diffusion, interface evolution, and other unknown dynamic processes, will provide profound insights into the study … Read more
Transcatheter Left Atrial Appendage Occlusion (LAAO) is an effective method for preventing stroke in patients with atrial fibrillation and has been widely used in clinical practice in recent years. However, there are still some challenges with LAAO, among which device-related thrombosis (DRT) after the procedure is an important concern. Previous studies have shown that the … Read more
