Suicide inhibition of alpha-oxamine synthases:structures of the covalent adducts of 8-amino-7-oxononanoate synthase with trifluoroalanine [PDF]

, 2006
The suicide inhibition of the α-oxamine synthases by the substrate analog, L-trifluoroalanine was investigated. The inhibition resulted in the formation of a complex with loss of all three fluorine atoms.

Two Material Properties from One Wavelength‐Orthogonal Photoresin Enabled by a Monochromatic Laser Integrated Stereolithographic Apparatus (Mono LISA)

Advanced Materials, Volume 37, Issue 13, April 2, 2025.
A single object with dual properties – degradable and non‐degradable – is fabricated in a single print simply by switching the printing colors. The advanced multi‐material printing is enabled by the combination of a fully wavelength‐orthogonal photoresin and a monochromatic tunable laser printer, paving the way for precise multi‐material ...

Thermo‐responsive topological metamorphosis in covalent‐and‐supramolecular polymer architectures

Aggregate, Volume 3, Issue 6, December 2022., 2022
We report a thermo‐responsive topological metamorphosis in covalent‐and‐supramolecular polymer (CSP) architectures wherein supramolecular graft polymer (SGP) transforms into supramolecular polymer network (SPN) based on collaborative dynamic covalent bond chemistry and host−guest chemistry.

Reversible Reaction of Cobalt(II) Tetrasulfophthalocyanine with Molecular Oxygen

CHIMIA, 1972
Absorption spectra of solutions of Co(II), Fe(III) and Mn III) tetrasulfophthalocyanines have been studied under aerobic and anaerobic conditions. CoTSP reacts reversibly with molecular oxygen forming a stable oxygen adduct. The oxygen adduct with FeTSP

Serine Proteases: an Ab Initio Molecular Dynamics Study [PDF]

arXiv, 1999
In serine proteases (SP's), the H-bond between His-57 and Asp-102, and that between Gly-193 and the transition state intermediate play a crucial role for enzymatic function. To shed light on the nature of these interactions, we have carried out ab initio molecular dynamics simulations on complexes representing adducts between the reaction intermediate ...

Harnessing Synergistic Cooperation of Neighboring Active Motifs in Heterogeneous Catalysts for Enhanced Catalytic Performance

Advanced Materials, EarlyView.
This review examines the critical role of neighboring active motifs in heterogeneous catalysts, emphasizing how their synergistic cooperativity can be rationally designed to modulate catalytic properties. The discussion centers on the modulation of electronic and geometric structures, categorizing the catalytic systems into metal‐acid (Brønsted/Lewis ...
