Cr(III) and Cr(0) complexes are earth-abundant alternatives to photosensitizers that are commonly made from precious metals.

Renewable materials, viz. cellulose, chitin, chitosan and cyclodextrins are promising alternatives to petroleum-based feedstocks for CO₂ sequestration.

Phosphine oxide-containing alkynylgold(III) complexes were synthesized and fabricated into solution-processable OLEDs with high EQEs and small efficiency roll-offs.

A cosolvent that is used to guide the self-assembly of amphiphiles in water causes abrupt structural changes, as well as non-linear behavior in the molecular dynamics of the amphiphiles.

A tris((1-ethyl-benzoimidazol-2-yl)methyl)amine (BIMEt₃) complex of P³⁺ is oxidized with XeF₂ to access [PF₂(BIMEt₃)]³⁺ representing the first structurally characterized example of a phosphorus(V)³⁺ cation.

White-light emission from a single molecule was realized and tuned via multistimuli including excitation, solvent polarity, temperature and host–guest interactions.

Usual oxygen bases decompose M/NHC complexes to give “NHC-free” metal species and azolones.

A series of redox tunable polyoxometalate–bodipy conjugates display variable charge transfer dynamics occuring down to 54 ps.

We demonstrate a novel hydrogel material to facilitate direct bioelectrochemistry of a wide range of redox proteins and enable ATP-independent electroenzymatic reduction of N₂ by nitrogenase.

Extra-synaptic exocytosis is an essential component of cellular communication. A knowledge gap exists in the exocytosis of the non-redox active transmitter acetylcholine. Using the nano-interface between two immiscible electrolyte solutions and scanning electrochemical microscopy, a high resolution spatiotemporal study of acetylcholine exocytosis is shown from individual neuronal soma.

We report novel structure–activity relationships and explore the chemical state and structure of catalytically active sites under operando conditions during the electrochemical CO₂ reduction reaction (CO₂RR) catalyzed by a series of porous iron–nitrogen–carbon (FeNC) catalysts.

We describe the first application of stapled peptides in human platelets. Bim BH3 stapled peptides are used to overcome the limitations of traditional methods and uncover a new role for Bim in platelet activation.

Simple acid–base properties explain the differences in amide and imide dimerisation, and represent an alternative to the secondary interactions hypothesis.

Realization of a hitherto elusive unsupported η⁶ binding mode of benzene to a copper(I) cation employing silylene as a ligand. The back-donation from Cu to Si(II) diminishes the repulsion between d-electrons and the benzene ring and enforces the η⁶ binding mode.

The surface charge and chemistry of a protein determines its ability to facilitate biomimetic mineralisation.

A mechanistic investigation of the acid-catalysed redox-neutral arylation of ynamides intertwining ESI-MS, DFT and experiments reveals diverse pathways available from an otherwise simple-looking transformation.

The (photo) chemical oxidation of a (TAML)Fe^III complex using outer-sphere oxidants results in valence tautomerisation and C–H activation governed by exogenous anions.

Nickel-modified covalent triazine frameworks effectively reduced CO₂ to CO because adsorbed COOH was stabilized on the coordinatively-unsaturated Ni atoms in CTF.

QM/MM simulations elucidate the self-repair mechanism of the cyclobutane pyrimidine dimer.

Despite recent remarkable advances in microscopic techniques, it still remains very challenging to directly observe the complex structure of cytoplasmic organelles in live cells without a fluorescent label.

Electronic effects provide a general mechanistic scenario for rationalizing photocatalytic water reduction activity with aminopyridine cobalt complexes.

Replacing the O-linked saccharide in the bacteriocin glycocin F with an S-linked version results in a peptidomimetic that increases the bacteriostatic effect.

The novel synthetic strategy for preparation of ester linked ubiquitinated proteins was developed. We found that the ester linkage could be cleaved by deubiquitinases with different efficiency relative to the isopeptide-linked substrate.
