Silicon Carbide Nanostructures as Potential Carbide Material for Electrochemical Supercapacitors: A Review.

Silicon carbide (SiC) is a very promising carbide material with various applications such as electrochemical supercapacitors, photocatalysis, microwave absorption, field-effect transistors, and sensors. Due to its enticing advantages of high thermal stability, outstanding chemical stability, high thermal conductivity, and excellent mechanical behavior, it is used as a potential candidate in various fields such as supercapacitors, water-splitting, photocatalysis, biomedical, sensors, and so on. This review mainly describes the various synthesis techniques of nanostructured SiC (0D, 1D, 2D, and 3D) and its properties.

Synthesis and Characterization of ZnO-TiO/Carbon Fiber Composite with Enhanced Photocatalytic Properties.

Herein, we prepared a novel photocatalytic ZnO-TiO loaded carbon nanofibers composites (ZnO-TiO-CNFs) via electrospinning technique followed by a hydrothermal process. At first, the electrospun TiO NP-embedded carbon nanofibers (TiO-CNFs) were achieved using electrospinning and a carbonization process. Next, the ZnO particles were grown into the TiO-CNFs via hydrothermal treatment.

Effect of high-dose oral rabeprazole on recurrent bleeding after endoscopic treatment of bleeding peptic ulcers.

Background. The aim of this study was to compare the effect of high-dose oral rabeprazole versus high-dose IV PPI on rebleeding after endoscopic treatment of bleeding peptic ulcers. Methods.

Is percutaneous endoscopic gastrostomy tube placement safe in patients with ventriculoperitoneal shunts?

Aim: To investigate whether percutaneous endoscopic gastrostomy (PEG) tube placement is safe in patients with ventriculoperitoneal (VP) shunts.

Methods: This was a retrospective study of all patients undergoing PEG insertion at our institution between June 1999 and June 2006. Post-PEG complications were compared between two groups according to the presence or absence of VP shunts.

[Spontaneous resolution of multiple fundic gland polyps after cessation of treatment with omeprazole].

Fundic gland polyps (FGPs) are the most common type of gastric polyps, found primarily in the fundus and body of stomach. Long term use of proton pump inhibitor (PPI) is known to be associated with certain histological changes of the normal gastric mucosa including parietal cell hyperplasia and fundic gland cysts. We experienced a patient who showed spontaneous resolution of multiple FGPs after the cessation of omeprazole.
