A new thiolate/disulfide mediator was designed and synthesized by employing DFT calculations as a guide. It possesses high transparency to visible light, a very attractive feature for bifacially active transparent DSCs that require a highly transparent counter electrode (CE). Compared to the reported and most promising thiolate/disulfide mediator T(-)/T(2), this new analogous mediator produced ...

No periodate oxidation on chitin? For the first time, direct selective alkaline of chitin led to isolation ordered domains as uniform anisotropic and zwitterionic ChNCs after simultaneous removal non-ordered domains.

Small cation size along with removal of trace iron from the electrolyte solution enables practical use earth-abundant nickel oxide electrodes for selective oxidation organic molecules over water in aqueous solutions.

Spatially resolved activity profiling along a fixed bed of powder catalyst during selective oxidation propylene to acrolein revealed gradients in the gas phase composition and temperature, thus reaction network.

A novel porous fluorine doped tin oxide (PFTO) conductive framework was introduced to counter electrodes (CEs) for dye-sensitized solar cells (DSSCs). When modified by platinum (Pt) or carbon (C), the PFTO conductive framework displays high catalytic activity to I(-)/I3(-) redox couples. Power conversion efficiencies of 6.09% and 5.81% were obtained in the DSSCs based on Pt and C modified PFTO ...

A promising strategy for increasing the energy density of Li-ion batteries is to substitute a multivalent (MV) metal for the commonly used lithiated carbon anode. Magnesium is a prime candidate for such a MV battery due to its high volumetric capacity, abundance, and limited tendency to form dendrites. One challenge that is slowing the implementation of Mg-based batteries, however, is the devel...

The synthesis and characterisation of an immobilised molecular ruthenium catalyst for the selective oxidation organic substrates in fully aqueous media with high selectivity over competing oxygen evolution reaction is reported.

We report here the selective determination of dopamine (DA) using quantum-sized gold nanoparticles coated with charge selective ligands. Glutathione protected gold nanoparticles (GS-Au(25)) were synthesized and immobilized into a sol-gel matrix via thiol linkers. The GS-Au(25) modified sol-gel electrode was found to show excellent electrocatalytic activity towards the oxidation of DA but no act...

An efficient organocatalytic method for chemoselective aerobic oxidation of secondary benzylic alcohols within lignin model compounds has been identified. Extension to selective oxidation in natural lignins has also been demonstrated. The optimal catalyst system consists of 4-acetamido-TEMPO (5 mol %; TEMPO = 2,2,6,6-tetramethylpiperidine-N-oxyl) in combination with HNO3 and HCl (10 mol % each)...
