Radical-based tuning the surface functionality of MXene
Olshtrem, A. ; Chertopalov, Sergii ; Guselnikova, O. ; Švorčík, V. ; Lyutakov, O.
The family of MAX phases and their derivative MXenes are continuously growing in terms of both crystalline and composition varieties. MXenes are a new family of two-dimensional (2D) transition metal carbides, carbonitrides and nitrides, with a general formula Mn+1AXn, where n = 1–3, M denotes a transition metal, A is an element such as aluminum or silicon, and X is either carbon or nitrogen. Considering the various elemental composition possibilities, surface functional tunability, various magnetic orders, and large spin–orbit coupling, MXene can truly be considered as multifunctional materials that can be used to realize highly correlated phenomena.

A Kitchen Degreaser Containing Monoethanolamine Can Alter Indoor Aerosol Composition for Days.
Schwarz, Jaroslav ; Makeš, Otakar ; Ondráček, Jakub ; Cusack, Michael ; Talbot, Nicholas ; Vodička, Petr ; Kubelová, Lucie ; Ždímal, Vladimír
Using of such degreaser and consequences related to indoor aerosol are described in this study. Monoethanolamine, a part of a commercial degreaser being used in kitchens, was able to replace ammonium in its sulfate and nitrate salts in the indoor environment, while those salts usually form up to half of PM2.5 aerosol mass indoors.
