Engineering of Yolk/Core–Shell Structured Nanoreactors for Thermal Hydrogenations [PDF]

Small, 2020
AbstractHeterogeneous hydrogenation reactions are of great importance for chemical upgrading and synthesis, but still face the challenges of controlling selectivity and long‐term stability. To improve the catalytic performance, many hydrogenation reactions utilize special yolk/core–shell nanoreactors (YCSNs) with unique architectures and advantageous ...

Skyrmion Spin Structure of Exchange-Coupled Magnetic Core-Shell Nanodisk

, 2015
We study the skyrmion spin texture created in a cylindrical exchange-coupled magnetic core-shell nanodisk (Co/CoPt) in the absence of the Dzyaloshinskii-Moriya interaction.

Field‐Tuneable Diamagnetism in Ferromagnetic–Superconducting Core–Shell Structures [PDF]

Advanced Functional Materials, 2011
AbstractThree dimensional ferromagnet–superconductor core–shell structures are realized by electrocrystallisation and their magnetic properties investigated. We observe fully re‐entrant core superconductivity in increasing fields that survives well above the bulk critical field due to compensation effects.

Reconstructing enzyme evolution by protein engineering

FEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Structure of a trimeric bacterial microcompartment shell protein, EtuB, associated with ethanol utilization inClostridium kluyveri [PDF]

, 2009
It has been suggested that ethanol metabolism in the strict anaerobe Clostridium kluyveri occurs within a metabolosome, a subcellular proteinaceous bacterial microcompartment. Two bacterial microcompartment shell proteins [EtuA (ethanol utilization shell

Analysing the significance of small conformational changes and low occupancy states in serial crystallographic data

FEBS Open Bio, EarlyView.
This protocol paper outlines methods to establish the success of a time‐resolved serial crystallographic experiment, by means of statistical analysis of timepoint data in reciprocal space and models in real space. We show how to amplify the signal from excited states to visualise structural changes in successful experiments.

UiO‐66 metal–organic frameworks in biomedicine: From structural tunability to bioimaging, photodiagnostics, and photodynamic cancer therapy

FEBS Open Bio, EarlyView.
UiO‐66(Zr) metal–organic frameworks are chemically stable, biocompatible, and highly tunable nanomaterials. Their modular structure enables controlled drug delivery, multimodal bioimaging, and light‐activated photodynamic therapy, supporting integrated diagnostic and therapeutic (theranostic) applications in cancer and biomedical research.

APPLICATION OF MAGNETIC NANOPARTICLES WITH STRUCTURE OF CORE-SHELL, AS BACTERICIDAL [PDF]

Immunology and Inflammation Diseases Therapy, 2018
Initially, magnetic nanoparticles (MNP) Fe3O4 are synthesized by a chemical correlation method and its core / shell structure is detected using SEM, FT-IR analysis. The purpose of this production was to use the nanoparticle performance level in the absorption of antibiotics, namely, ampicillin (amp).
