Enabling simultaneous redox transformation of toxic chromium(VI) and arsenic(III) in aqueous media—A review
PublicationSimultaneous conversion of most harmful As(III) and Cr(VI) to their less toxic counterparts is environmentally desirable and cost-effective. It has been confirmed that simultaneous oxidation of As(III) to As(V) and reduction of Cr(VI) to Cr(III) can occur via free radical or mediated electron transfer processes. While Cr(VI) is reduced by reacting with H•, eaq−, photoelectron directly or undergoing ligand exchange with H2O2 and...

3D mesoporous α-Co(OH)2 nanosheets electrodeposited on nickel foam: A new generation of macroscopic cobalt-based hybrid for peroxymonosulfate activation
PublicationCobalt-based catalysts with high stability and facile recovery for heterogeneous peroxymonosulfate (PMS) activation are still rather sparse and therefore highly desirable. Herein, 3D mesoporous α-Co(OH)2 nanosheets was created on robust nickel foam (NF) via facile electrodeposition approach at 6 mA/cm2 for only 400 s. Almost complete removal of phenol can be achieved within 7 min with a degradation rate of 0.39 min−1, 2 times higher...

Polityka, prestiż i odreagowanie. Dom jednorodzinny w okresie transformacji
PublicationPolskie mieszkalnictwo stanowiło jeden z obszarów odzwierciedlających polityczno-gospodarcze zmiany po 1989 roku. Niespotykana wcześniej wolność wyboru oraz szybki wzrost zamożności przedefiniowały aspiracje mieszkaniowe Polaków. Zanim zniknęła żelazna kurtyna, Polacy żyli w opierającym się na medialnym przekazie przeświadczeniu, że na „mitycznym” Zachodzie każdy posiada dom i samochód. Te wzorce, w zestawieniu z błyskawicznym...
