Engineered Metal–Organic Frameworks‐Based Materials for Environmental Detection

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Engineered metal–organic frameworks (MOFs) regulated by various material modification strategies are discussed for environmental contaminant detection under different sensing mechanisms, providing future improvements of MOFs in environmental detection. Sensitive and selective detection of contaminants is crucial for environmental protection.

Monoclonal antibodies against metalloporphyrins. Specificity of interaction with structurally different metalloporphyrins

FEBS Letters, 1994
Monoclonal antibodies against Pd‐coproporphyrin I have been obtained. The antibody specificity for free as well as for conjugated Pd‐coproporphyrin I is characterized. Affinity constants are estimated for 3 monoclonal antibodies effectively interacting with free Pd‐coproporphyrin I.

Carbon monoxide binding to iron porphyrins [PDF]

, 1979
The carbon monoxide affinities of iron complexes of meso-tetra (α,α,α,α-o-pivalamidophenyl)porphyrin (the "picket fence" porphyrin) and of a "picket fence" porphyrin derivative with an appended axial base have been measured in solution and compared with ...

Projector self-consistent DFT+U using non-orthogonal generalized Wannier functions [PDF]

, 2010
We present a formulation of the density-functional theory + Hubbard model (DFT+U) method that is self-consistent over the choice of Hubbard projectors used to define the correlated subspaces.

Active Site Determination of Heterogenized Molecular Electrocatalysts

Advanced Energy Materials, Volume 16, Issue 17, 6 May 2026.
Here, we develop a methodology to examine the active site availability of immobilized transition‐metal molecular complexes via cyclic voltammetry. By using varying loadings of the molecular complex FeTPP physically immobilized onto Vulcan Carbon, we show the influences of FeTPP/VC ratios on the total number of active sites.

Manganese Porphyrin‐Catalyzed One‐Pot Oxidation of Lupeol: Efficient Conversion of Its Terminal Alkene Into Carboxylic Acids

Chemistry &Biodiversity, Volume 23, Issue 5, May 2026.
Manganese porphyrin catalyst enables green PhI(OAc)2 oxidation of lupeol in ethyl acetate, achieving 94% conversion and the formation of eight products, including selective C20 olefin transformations and one‐pot conversion of the isopropenyl group to carboxylic acids, all without the need of C3‐OH protection step.
