Titanium metal-organic frameworks for photocatalytic CO conversion through a cycloaddition reaction.

The elevated levels of CO in the atmosphere have been a major concern for environmental scientists. Capturing CO gas and its subsequent conversion to useful organic compounds is one of the avenues that have been extensively studied in the last decade. The photocatalytic cycloaddition of CO is a promising approach for effective CO capture and the production of value-added chemicals such as cyclic carbonates.

Hexagonal Layer Manganese Metal-Organic Framework for Photocatalytic CO Cycloaddition Reaction.

A novel manganese metal-organic framework (Mn-MOF) termed UAEU-50 assembled from a benzenedicarboxylate linker (BDC) and trinuclear manganese clusters was synthesized and fully characterized using different spectroscopic and analytic techniques (e.g., X-ray powder diffraction, UV-vis diffuse reflectance spectroscopy, thermogravimetric analysis, scanning electron microscopy, and energy-dispersive X-ray spectroscopy).

Elective neck dissection in unilateral carcinomas of the tongue: Unilateral versus bilateral approach.

Purpose: Elective neck dissection (END) is a common primary treatment strategy for oral tongue squamous cell carcinoma (OTSCC), although uncertainty remains regarding the necessary extent of END for strictly unilateral early stage OTSCC. The authors evaluated two END variations, unilateral and bilateral, to determine the optimal extent.

Materials And Methods: A retrospective cohort study was performed on patient data from two departments of oral and maxillofacial surgery.
