Metal-organic framework derived copper catalysts for CO2 to ethylene conversion

Jun Li

The electrochemical reduction of CO2 to ethylene provides a carbon-neutral avenue for the conversion of CO2 to value-added fuels and feedstocks, so contributing to the storage of intermittent renewable electricity. The exploration of efficient electrocatal ...

Single molybdenum center supported on N-doped black phosphorus as an efficient electrocatalyst for nitrogen fixation

Xiao Zhou

Ammonia (NH3) is one of the most significant industrial chemical products due to its wide applications in various fields. However, the production of NH3 from the electrochemical nitrogen (N-2) reduction reaction (NRR) under ambient conditions is one of the ...

Enantioselective Ruthenium(II)-Catalyzed Access to Benzonorcaradienes by Coupling of Oxabenzonorbornadienes and Alkynes

Nicolai Cramer, Shouguo Wang, Sung Hwan Park

Benzonorcaradienes and benzonorcarenes are attractive scaffolds that occur in natural products as well as biologically active compounds. However, there is a significant gap in the current synthetic toolbox as methods to access benzonorcaradiene enantiosele ...

"Doubly Orthogonal" Labeling of Peptides and Proteins

Jérôme Waser, Beat Fierz, Nora Guidotti, Raphaël Michel Henri Simonet-Davin, Romain Gaëtan Tessier, Javier De Ceballos Cerrajeria

Herein, we report a cysteine bioconjugation methodology for the introduction of hypervalent iodine compounds onto biomolecules. Ethynylbenziodoxolones (EBXs) engage thiols in small organic molecules and cysteine-containing peptides and proteins in a fast a ...

Dual-Facet Mechanism in Copper Nanocubes for Electrochemical CO2 Reduction into Ethylene

Raffaella Buonsanti, Jianfeng Huang, Giulia Mangione

The product selectivity in the electrochemical reduction of carbon dioxide depends on the structure of the copper electrode. Cube-shaped copper catalysts, enclosed by {100} terraces, {110} edges, and {111} corners, exhibit a size-dependent enhanced only se ...

Piano Stool Aminoalkylidene-Ferracyclopentenone Complexes from Bimetallic Precursors: Synthesis and Cytotoxicity Data

Paul Joseph Dyson, Lucinda Kate Batchelor

The reaction of pyrrolidine with a series of cationic diiron cyclopentadienyl complexes containing a bridging vinyliminium ligand gives access to piano stool monoiron complexes based on a five-membered metallacycle that includes a vinyl-aminoalkylidene moi ...

Development of Catalytic Asymmetric C-H Functionalizations with Chiral Cyclopentadienyl Iridium(III) Complexes

Yun-Suk Jang

Cp*Ir(III) catalyzed C-H functionalization is a growing field, since it provides novel complementary reactivities, but enantioselective C-H functionalization reactions with this metal remain a niche. This thesis investigates CpXIr(III) catalyzed asymmetric ...

Controlling topology, dynamics and function of polymer brushes via post-polymerization modification

Piotr Mocny

Polymer brushes are a class of thin coatings, where each of chains is tethered to the underlying substrate via one chain end. Densely grafted polymer brushes feature a stretched chain conformation, which in a unique way enhances their lubrication and non-b ...

A Cobalt-Iron Double-Atom Catalyst for the Oxygen Evolution Reaction

Xile Hu, Duncan Thomas Lindsay Alexander, Lichen Bai

Single-atom catalysts exhibit well-defined active sites and potentially maximum atomic efficiency. However, they are unsuitable for reactions that benefit from bimetallic promotion such as the oxygen evolution reaction (OER) in an alkaline medium. Here we ...

Catalytic valorization of the acetate fraction of biomass to aromatics and its integration into the carboxylate platform

Jeremy Luterbacher, Benjamin Pierre Le Monnier, Masoud Talebi Amiri, Ydna Marie Questell-Santiago, Jher Hau Yeap, Bartosz Rozmyslowicz

In many plant species, the acetate fraction is the fourth most prominent fraction by weight after cellulose, hemicellulose and lignin, and can be easily extracted as a single stable molecule, acetic acid, at high yields. Despite this, upgrading the acetate ...

Recent Considerations in the Application of RAPTA-C for Cancer Treatment and Perspectives for Its Combination with Immunotherapies

Paul Joseph Dyson, Patrycja Nowak-Sliwinska

The organometallic ruthenium(II) [Ru(arene)Cl2PTA] PTA - 1,3,5-triaza-7-phosphaadamantane compound, RAPTA-C, represents an innovative anti-cancer therapeutic and a better-tolerated alternative to platinum (Pt)-based chemotherapeutic drugs in the treatment ...
