Iron metal-organic framework nanofiber membrane for the integration of electro-Fenton and effective continuous treatment of pharmaceuticals in water.

In this study, an iron metal-organic framework (Fe-MOF) was synthesized and immobilized by electrospinning technique with the objective of obtaining a membrane composed of nanofibers of this material (Fe-MOF nanofiber membrane). The characterization performed by XRD, TEM, SEM, EDS mapping and FTIR confirmed the correct synthesis of Fe-MOF as well as its correct retention in the elaborated membranes. The usefulness and effectiveness of the Fe-MOF nanofiber membrane as a catalyst for the electro-Fenton process was evaluated by performing sulfamethoxazole degradation tests.

Septic cardioembolic stroke secondary to infective endocarditis in a young patient with rheumatic heart disease: a case report.

The risk of stroke due to infective endocarditis is particularly high during the first week. Moreover, in low-resource settings where imaging access is limited, and diagnostic pathways are inaccurate the risk further increases. In addition to antibiotic therapy, treatment may include intravenous thrombolysis, with high risk of hemorrhagic complications in patients with infective endocarditis or mechanical thrombectomy.

Digital assessment of supracrestal tissue attachment and its correlation with dentogingival components.

Background: The aim of this study is to measure, in vivo, the supracrestal tissue attachment dimensions (STADs) by means of a noninvasive digital method and to investigate the association between STADs and gingival thickness (GT), tooth position, tooth length, tooth width, keratinized tissue width (KTW), buccal bone thickness (BBT), and bone crest (BC) level.

Methods: Nineteen periodontally healthy subjects who previously received full mouth periodontal charting, cone beam computed tomography, and intraoral scan for the purpose of implant planning were included in the study. A digital imaging software was used for the superimposition of Digital Imaging and Communications in Medicine and stereolithography files, along with hard and soft tissue measurements.

One-pot synthesis of bimetallic Fe-Cu metal-organic frameworks composite for the elimination of organic pollutants via peroxymonosulphate activation.

A series of bimetallic of FeCu metal-organic frameworks (MOFs) have been synthesised using a solvothermal process by varying the ratio between the two metals. Further, the bimetallic MOF catalysts were characterised by X-ray powder diffraction, scanning electron microscopy, and infrared spectroscopy techniques. Their catalytic properties for activation of peroxymonosulphate (PMS) have been tested by the removal of a model dye, rhodamine B.

Heterogeneous electro-Fenton system using Fe-MOF as catalyst and electrocatalyst for degradation of pharmaceuticals.

In recent years, heterogeneous electro-Fenton processes have gained considerable attention as an alternative to homogeneous processes. In this context, the aim of this study is the use of a commercial iron metal-organic framework (Fe-MOF), Basolite® F-300, as a base material for the design of a heterogeneous electro-Fenton treatment system for the removal of antipyrine. Initially, the catalyst was applied as powder in aqueous solution and three key parameters of the electro-Fenton process (pH, Fe-MOF concentration and current density) were evaluated and optimized by a Central Composite Design Face Centred (CCD-FC) using antipyrine removal and energy consumption as response functions.
