Advanced oxidative degradation of monoethanolamine in water using ultraviolet light and hydrogen peroxide.

This study aims to develop a benign and commercially viable method for the degradation of monoethanolamine (MEA) in the aqueous phase an ultraviolet/hydrogen peroxide (UV/HO) advanced oxidation process (AOP). The current investigation is novel in terms of detailed kinetic analysis and degradation mechanisms; the impact of pH and UV light intensity on MEA degradation was thoroughly examined. pH 9 was identified as the optimal condition, achieving a degradation efficiency of 76.

A comprehensive review of the current progresses and material advances in perovskite solar cells.

Recently, perovskite solar cells (PSCs) have attracted ample consideration from the photovoltaic community owing to their continually-increasing power conversion efficiency (PCE), viable solution-processed methods, and inexpensive materials ingredients. Over the past few years, the performance of perovskite-based devices has exceeded 25% due to superior perovskite films achieved using low-temperature synthesis procedures along with evolving appropriate interface and electrode-materials. The current review provides comprehensive knowledge to enhance the performance and materials advances for perovskite solar cells.

Recent Advances in Molten-Carbonate Membranes for Carbon Dioxide Separation: Focus on Material Selection, Geometry, and Surface Modification.

Membranes for carbon dioxide permeation have been recognized as potential candidates for CO separation technology, particularly in the energy sector. Supported molten-salt membranes provide ionic routes to facilitate carbon dioxide transport across the membrane, permit the use of membrane at higher temperature, and offer selectivity based on ionic affinity of targeted compound. In this review, molten-carbonate ceramic membranes have been evaluated for CO separation.

Data article for adsorption of chemically activated fuller׳s earth and rice husk for removal of dri-marine reactive red dye.

Dyes are most commonly used in textile industries for colouring clothes. After colouring, dri-marine reactive red dye is drained into lakes and rivers, which is very hazardous for aquatic as well as human life. The treatment of this dye solution is necessary to make it clear before it is drained into river.

Photostable self-cleaning cotton by a copper(II) porphyrin/TiO2 visible-light photocatalytic system.

Thin films of meso-tetra(4-carboxyphenyl)porphyrinato copper(II) (CuTCPP) in conjunction with anatase TiO2 have been formed on cotton fabric. Their self-cleaning properties have been investigated by conducting photocatalytic degradation of methylene blue, coffee and wine stains under visible-light irradiation. CuTCPP/TiO2-coated cotton fabrics showed superior self-cleaning performance when compared to bare TiO2-coated cotton.

Intramolecular arene epoxidation by phosphadioxiranes.

Singlet oxygen reacts with binaphthyl phosphine derivatives such as 1,1'-binaphthyl di-tert-butyl phosphine to form the corresponding binaphthyl-2-oxide phosphine oxides. This new intramolecular arene epoxidation reaction proceeds with complete retention of stereochemistry. The binaphthyl-2-oxide di-tert-butyl phosphine oxide undergoes a slow "NIH-rearrangement" to form the corresponding hydroxylated product.
