Ni-Based Catalysts for CO Methanation: Exploring the Support Role in Structure-Activity Relationships.

The catalytic hydrogenation of CO to methane is one of the highly researched areas for the production of chemical fuels. The activity of catalyst is largely affected by support type and metal-support interaction deriving from the special method during catalyst preparation. Hence, we employed a simple solvothermal technique to synthesize Ni-based catalysts with different supports and studied the support role (CeO, AlO, ZrO, and LaO) on structure-activity relationships in CO methanation.

Buccal mucosal graft urethroplasty for anterior urethral stricture, experience from a low-income country.

Background/purpose: This study was conducted to present our experience in urethral mucosal graft urethroplasty to repair urethral stricture, as the first experience in our context.

Methods: This is a prospective hospital-based study that had been designed to review management outcomes of buccal mucosal graft urethroplasty for anterior urethral stricture from January 2017 to January 2019.

Results: The total number of involved patients was 60.

Heterostructured CoS/CuCoS@N-doped carbon hollow sphere for potassium-ion batteries.

Potassium ions batteries (PIBs) have been regarded as a promising choice for electrical energy storage technology due to the wide distribution of potassium resources. However, developing low-cost and robust earth-rich anode materials is still a major challenge for the practical and scalable usage of PIBs. Herein, for the first time, we developed nitrogen doped carbon coating CoS/CuCoS heterostructure (CoS/CuCoS@NCs) hollow spheres and evaluated as anode for PIBs.

Role of 18F-Fluorodeoxyglucose-Positron Emission Tomography/Computed Tomography Imaging in the Prediction of Prognosis in Patients With Indolent Lymphoma: Prospective Study.

Background: The role of fluorodeoxyglucose-positron emission tomography/computed tomography (FDG-PET/CT) in indolent lymphoma has been minimally studied.

Objective: This study aims to assess the value of FDG-PET/CT in predicting the prognosis of indolent lymphoma.

Methods: We prospectively recruited 42 patients with indolent lymphoma.
