Improvement of thermal stability of Ta-N film in Cu metallization by a Zr-Si interlayer [PDF]

E3S Web of Conferences, 2021
Ta-N (10 nm)/Zr (20 nm) film was grown on n-type (100) silicon wafer at various substrate temperatures in a rf magnetron sputtering system, followed by in situ deposition of Cu.

EnSite NavX mapping system guided implantation of a dual-chamber permanent pacemaker in a 41-year-old pregnant woman with a 4-year follow-up

BMC Cardiovascular Disorders, 2022
Background X-ray fluoroscopy has been the primary cardiac imaging modality in permanent pacemaker implantation (PPI) operations, but it inevitably results in radiation exposure for both operators and patients. Fluoroscopy is considered a contraindication,

Cathodal Transcranial Direct Current Stimulation Over the Right Temporoparietal Junction Suppresses Its Functional Connectivity and Reduces Contralateral Spatial and Temporal Perception

Frontiers in Neuroscience, 2021
The temporoparietal junction plays key roles in vestibular function, motor-sensory ability, and attitude stability. Conventional approaches to studying the temporoparietal junction have drawbacks, and previous studies have focused on self-motion rather ...

Atomic Force Microscope

Definitions, 2020
The scanning tunneling microscope is proposed as a method to measure forces as small as 10 N. As one application for this concept, we introduce a new type of microscope capable of investigating surfaces of insulators on an atomic scale.

Accurate prediction by AlphaFold2 for ligand binding in a reductive dehalogenase and implications for PFAS (per- and polyfluoroalkyl substance) biodegradation

Scientific Reports, 2023
Despite the success of AlphaFold2 (AF2), it is unclear how AF2 models accommodate for ligand binding. Here, we start with a protein sequence from Acidimicrobiaceae TMED77 (T7RdhA) with potential for catalyzing the degradation of per- and polyfluoroalkyl ...

Subcritical crack growth models for SiC fiber in air and steam: Low temperature data and possible effects of residual stress

Open Ceramics, 2023
Failure times (tf) and brittle creep strain rates (ἑ) for static fatigue of Hi-Nicalon™-S fiber tows were measured at 500 and 600 °C. These measurements added to those done previously at 700–1100 °C.

Directional microwave emission from femtosecond-laser illuminated linear arrays of superconducting rings

Scientific Reports, 2023
We examine the electromagnetic emission from two photo-illuminated linear arrays composed of inductively charged superconducting ring elements. The arrays are illuminated by an ultrafast infrared laser that triggers microwave broadband emission detected ...

Proposal of a Risk Scoring System to Facilitate the Treatment of Enteroenteric Intussusception in Peutz-Jeghers Syndrome

Gut and Liver, 2023
Background/Aims: Enteroenteric intussusception in Peutz-Jeghers syndrome (EI-PJS) is traditionally treated by surgery. However, enteroscopic treatment is a minimally invasive approach worth attempting.
