Preparation of Yb-Sb co-doped Ti/SnO electrode for electrocatalytic degradation of sulfamethoxazole (SMX).

To efficiently break down residual sulfonamide antibiotics in environmental water, Yb-Sb co-doped Ti/SnO electrodes were fabricated using a solvothermal method. The effect of different amounts of Yb doping on the properties of the electrodes was studied. When the atom ratio of Sn: Yb is 100 : 7.

Novel B and N Sites of One-Dimensional Boron Nitride Fiber: Efficient Performance and Mechanism in the Formaldehyde Capture Process.

Identification of adsorption centers with atomic levels of adsorbents is crucial to study the adsorption of formaldehyde (HCHO), especially for an in-depth understanding of the mechanism of HCHO capture. Herein, we investigate the HCHO adsorption performance of one-dimensional (1D) nanoporous boron nitride (BN) fiber, and explore the adsorption mechanism by density functional theory (DFT) calculations, including adsorption energy change and Bader charge change, and experimental study as well. Research shows that the 1D nanoporous BN fiber possesses a high concentration of Lewis pairs, which act as Lewis acid and Lewis base sites associated with the fiber's electron-deficient and electron-rich features.

Comparison of Ventilator-Associated Pneumonia and Surgical Site Infection between Two Methods of Tracheostomy.

Objective: To compare the incidence of ventilator-associated pneumonia (VAP) and surgical site infection (SSI) between percutaneous dilatational tracheostomy (PDT) and surgical tracheostomy (ST).

Methods: Data on 487 patients undergoing tracheostomy between 1 January 2014 and 30 September 2020 were reviewed. Patients were divided according to the surgical techniques.

A Meta-Analysis on Evaluation of Nosocomial Infections Amongst Patients in a Tertiary Care Hospital.

Background: Hospital-acquired infections, also known as nosocomial infections, are one of the many severe outcomes amongst patients in tertiary care hospitals. Hospital-acquired influenza is amongst the most common infection which has affected huge population.

Objective: We have performed a meta-analysis in order to summarize the effects of epidemiology and clinical characteristics in HAI.
