A facile control of epitaxial-like barium strontium titanate thin films with various Ba/Sr ratios synthesized by a hydrothermal-galvanic couple method

A Case of Esophageal Duplication Cyst Identified on Cardiac Point-of-Care Ultrasound

“…Symptoms can be gastrointestinal (dysphagia, epigastric, or retrosternal pain) or respiratory (cough, stridor, and wheezing) and are caused by compression of other mediastinal structures 12 . Imaging modalities to diagnose esophageal duplication cysts include computerized tomography, MRI, barium esophagram, and endoscopic ultrasound 11,13 . To our knowledge, diagnosis with cardiac POCUS has not previously been described in the literature.…”

“…To our knowledge, diagnosis with cardiac POCUS has not previously been described in the literature. Complications of esophageal duplication cysts include gastrointestinal obstruction, hemorrhage, cyst rupture, infection, and malignancy 13 . Surgical resection is the treatment of choice for symptomatic patients 14 …”

Ultra-high resistive switching current ratio and improved ferroelectricity and dielectric tunability performance in a BaTiO3/La0.7Sr0.3MnO3heterostructure by inserting a SrCoO2.5layer

“…In general, the dielectric tunability of BaTiO 3 films can be modulated by doping them with Sr and Sn elements, transitioning from the normal ferroelectric state to the relaxed ferroelectric state. [1][2][3][4][5][6][7] However, it is difficult to achieve both high dielectric tunability and low loss for the Ba 1−x Sr x TiO 3 ferroelectric film using linear dielectrics. 8 Growing the multilayer is an effective method for enhancing dielectric properties.…”
