The Mononuclear Metal-Binding Site of Mo-Nitrogenase Is Not Required for Activity

The biological N-2-fixation process is catalyzed exclusively by metallocofactor-containing nitrogenases. Structural and spectroscopic studies highlighted the presence of an additional mononuclear metal-binding (MMB) site, which can coordinate Fe in additio ...

In Vitro Biosynthesis of the [Fe]-Hydrogenase Cofactor Verifies the Proposed Biosynthetic Precursors

Xile Hu, Huijie Pan

In the FeGP cofactor of [Fe]-hydrogenase, low-spin Fe-II is in complex with two CO ligands and a pyridinol derivative; the latter ligates the iron with a 6-acylmethyl substituent and the pyridinol nitrogen. A guanylylpyridinol derivative, 6-carboxymethyl-3 ...

Carboxymethyl cellulose nanocomposite beads as super-efficient catalyst for the reduction of organic and inorganic pollutants

Shaik Mohammed Zakeeruddin

Carboxymethyl cellulose/copper oxide-nickel oxide (CMC/CuO-NiO) nanocomposite beads were prepared by facile, simple and environmentally friendlymethod. Initially, CuO-NiOwas prepared and applied for the catalytic reduction of 4-nitrophenol (4-NP). The resu ...

Oxidative Print Light Synthesis Thin Film Deposition of Prussian Blue

Hubert Girault, Emad Oveisi, Mounir Driss Mensi, Wanderson Oliveira Da Silva, Victor Costa Bassetto, Dominika Baster

Prussian blue (PB) and Prussian blue analogues (PBAs) are commonly synthesized by conventional methods, such as chemical precipitation, thermal decomposition, and electrochemical deposition. Herein, we have successfully synthesized Prussian blue by oxidati ...

A smart low molecular weight gelator for the triple detection of copper (II), mercury (II), and cyanide ions in water resources

Rosario Scopelliti

Novel supramolecular gelators based on quinoline-indolin-2-one structure were synthesized. These gelators formed stable organogels in a mixture of DMSO/H2O (1:1). The scanning electron microscopy (SEM), IR and NMR spectroscopies, and rheological measuremen ...

Sensing the Spin of an Individual Ce Adatom

Wolf-Dieter Schneider, Markus Ternes

The magnetic moment of rare earth elements originates from electrons in the partially filled 4f orbitals. Accessing this moment electrically by scanning tunneling spectroscopy is hampered by shielding of outerlying orbitals. Here, we show that we can detec ...

Polymeric room-temperature molten salt as a multifunctional additive toward highly efficient and stable inverted planar perovskite solar cells

Ulf Anders Hagfeldt, Bowen Yang, Jiabao Yang, Jiajia Suo, Shilong Wang, Ziwei He, Chao Tang

The inferior power conversion efficiency (PCE) compared to their regular counterparts (n-i-p) and undesirable stability issues of inverted (p-i-n) perovskite solar cells (PSCs) are the foremost issues hindering their commercialization. Here, for the first ...

The atomic-resolution crystal structure of activated [Fe]-hydrogenase

Xile Hu, Matthew Wodrich

Hydrogenases are promising templates for constructing new H-2-based catalysts. [Fe]-hydrogenase, which features an ironguanylylpyridinol (FeGP) cofactor, catalyses a reversible hydride transfer from H-2 to methenyl-tetrahydromethanopterin (methenyl-H4MPT+, ...

Controlling Ferromagnetic Ground States and Solitons in Thin Films and Nanowires Built from Iron Phthalocyanine Chains

Gabriel Aeppli

Iron phthalocyanine (FePc) is a molecular semiconductor whose building blocks are 1D ferromagnetic chains. It is shown that its optical and magnetic properties are controlled by the growth strategy, obtaining extremely high coercivities of over 1 T and mod ...

Atomically dispersed Fe3+ sites catalyze efficient CO2 electroreduction to CO

Xile Hu, Lichen Bai, Jun Gu

Currently, the most active electrocatalysts for the conversion of CO2 to CO are gold-based nanomaterials, whereas non-precious metal catalysts have shown low to modest activity. Here, we report a catalyst of dispersed single-atom iron sites that produces C ...
