Minimal ATP‐Independent N2‐Reducing Systems Defined by L‐Cluster‐Bound Nitrogenase Assembly Platforms

open access: yesAngewandte Chemie, EarlyView.
Association of the L‐cluster with the nitrogenase assembly proteins NifEN (NifENL) or NifB (NifBL) intrinsically endows these proteins with N2‐reducing activity, enabling in vitro N2‐reduction by NifENL and NifBL when supplied with chemical reductants or photoexcited quantum dots while supporting in vivo N2‐fixation in NifENL‐ and NifENL‐expressing ...

Cathodic Optimization of a MFC for Energy Recovery from Industrial Wastewater

open access: yesChemical Engineering Transactions, 2014
In a photosynthetic MFC with algae at cathodic compartment, algae use inorganic carbon source, carbon dioxide, and sunlight and produce oxygen by photosynthesis. The oxygen produced is used at cathode as electron acceptor.

Dipole‐Manipulated Built‐In Electric Field Enables Ultrafast Charge Separation in Perylene Diimide Polymers for Photoelectrochemical Water Splitting

open access: yesAdvanced Science, EarlyView.
Molecular dipole engineering in dendritic perylene diimide polymers through nitrogen‐rich heterocyclic linkers amplifies the built‐in electric field, enabling sub‐picosecond charge separation and efficient multi‐electron accumulation. This structure–dynamics–performance relationship establishes a versatile design strategy for high‐performance organic ...

Visible‐Light Sensitized Isomerization in the Lipid Bilayer Enables Activation of a Transmembrane Transporter

open access: yesAngewandte Chemie, EarlyView.
A stiff‐stilbene‐based transmembrane anion transporter is isomerized by energy transfer from a ruthenium tris(bipyridyl) photosensitizer in the lipid bilayer. This sensitized isomerization allows activation of chloride transport using visible instead of UV light, without the need to chemically modify the stiff‐stilbene photoswitch.

Effects of diffuse light on radiation use efficiency depend on the response of stomatal conductance to dynamic light intensity

open access: yesFrontiers in Plant Science, 2016
The stimulating effect of diffuse light on radiation use efficiency (RUE) of crops is often explained by the more homogeneous spatial light distribution, while rarely considering differences in temporal light distribution at leaf level.

Controlling Near‐Infrared Fluorescence‐to‐Phosphorescence Ratios and Triplet Lifetimes in Rhodium(I) Dimers via Primary and Secondary Coordination Sphere Effects

open access: yesAngewandte Chemie, EarlyView.
RhI dimers with bridging aryl isocyanide and di‐phosphine ligands show NIR‐I or NIR‐II fluorescence/phosphorescence, depending on the ligands and conformational rigidity at the Rh2 core. Rh‐Rh interactions can be tuned by peripheral modification of the aryl isocyanide ligand, resulting in a rigid Rh2 core and improved photophysical properties ...

An Artificial Molecular Pump Powered by Light

open access: yesAngewandte Chemie, EarlyView.
A minimal rotaxane‐based supramolecular system functions as a light‐powered molecular pump, capturing macrocycles from solution and concentrating them within an intramolecular compartment. Repeated azobenzene photoisomerization modulates the binding and kinetic barriers of threading and shuttling, generating a photon‐driven energy ratchet that sustains
