2D kinematics of the edge-on spiral galaxy ESO 379-G006

open access: yes, 2012
We present a kinematical study of the nearly edge-on galaxy ESO 379-G006 that shows the existence of extraplanar ionized gas. With Fabry-Perot spectroscopy at H-alpha, we study the kinematics of ESO 379-G006 using velocity maps and position-velocity ...

Suppressing Dendrite Formation through Au‐Driven Interfacial Engineering for Solid‐State Lithium‐Metal Batteries

open access: yesAdvanced Energy Materials, EarlyView.
A thin gold nanolayer on lithium metal enables stable and uniform lithium plating in solid‐state batteries, enabling nearly 1 year and 11 months of continuous operation. The conductive coating lowers interfacial resistance, suppresses dendrite growth, and improves cycling stability, attributed to homogeneous deposition of Li+ on the gold layer ...

Erosion behavior of EB-PVD 7YSZ coatings under corrosion/erosion regime: Effect of TBC microstructure and the CMAS chemistry

open access: yesJournal of the European Ceramic Society, 2018
Aero-engines operating in dust-laden environments often encounter a lot of dust/sand that causes a severe problem to the TBCs by means of erosion. As the turbine entry temperatures are rising, molten sand is also a big concern to the life-time of TBCs ...

Nationwide Real‐World Modeling of Surgical Outcomes in Elderly Patients: Incorporating Geriatric‐Specific Risk Factors Into Prediction of Mortality and Morbidity

open access: yesAnnals of Gastroenterological Surgery, EarlyView.
A reliable and effective risk prediction model for mortality and morbidity in elderly patients undergoing gastroenterological surgeries was developed and validated. Geriatric‐specific risk factors, including the newly added variables in the NCD registry, along with age, were identified as significant contributors to the model. ABSTRACT Aim As the aging

Intravascular Lithotripsy Is Associated With Superior Clinical Outcomes Compared to Atherectomy: A Large‐Scale, Propensity‐Matched Analysis

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Coronary artery disease (CAD) with severe calcification remains a growing challenge in percutaneous coronary intervention (PCI). Atherectomy (ATH) has long been used for plaque modification, whereas intravascular lithotripsy (IVL) has emerged as a promising alternative. Large‐scale comparative data on long‐term outcomes are limited.
