Ferritin Iron Mineralisation: Route of Fe3+ Transfer From the Ferroxidase Centre to the Inner Cavity of Human H‐Chain Ferritin

Angewandte Chemie, EarlyView.
Proposed mechanism for Fe3+ transport from the FoC (sites 1 and 2) of human H‐chain ferritin following oxidation of the di‐Fe2+ form. Glu61, aided by the flexibility of its sidechain, plays a key role in coordinating Fe3+ at three sites (3, 4 and 5) that mark out the transit route.

ABHD17C‐Mediated S‐Depalmitoylation of BCL6B Enhances CD24 Transcription to Resist Macrophage Phagocytosis in Pancreatic Cancer

Advanced Science, EarlyView.
ABHD17C‐mediated depalmitoylation of BCL6B at Cys442 blocks its nuclear import and triggers ubiquitin‐dependent degradation, attenuating transcriptional repression of the anti‐phagocytic signal CD24. This mechanism enables pancreatic cancer cells to evade macrophage phagocytosis and fosters an immunosuppressive microenvironment.

Synthesis of Cyclopropene‐Modified Fatty Acids Allows Single‐Cell Quantification of Uptake by Immune Cells

Angewandte Chemie, EarlyView.
Cyclopropene fatty acids have been made that allow the study of fatty acid uptake in complex mixtures of immune cells with single cell resolution and combined with metabolic and proteomic analysis so that for the first time nutrient uptake can be correlated to the phenotype of single immune cell.

SPICE‐Compatible Compact Modeling of Cuprate‐Based Memristors Across a Wide Temperature Range

Advanced Electronic Materials, EarlyView.
A physics‐guided compact model for YBCO memristors is introduced, incorporating carrier trapping, field‐induced detrapping, and a differential balance equation to describe their switching dynamics. The model is compared with experiments and implemented in LTspice, allowing realistic circuit‐level simulations.

Dielectrophoresis of sub-micrometre particles

, 1998
The aim of this PhD project was to develop the technology of dielectrophoresis on the sub-micrometre scale and to use DEP to manipulate sub-micrometre particles and measure their dielectric properties. Of particular interest was the application of DEP to

The Influence of Residual Ion Drift During Programming of Chip‐Integrated Nanoscale HfO2‐Based Memristive Devices

Advanced Electronic Materials, EarlyView.
1T1R‐arrays combining filamentary‐type memristors and CMOS transistors offer great potential for energy‐efficient analog hardware accelerators. Here, transient SET analysis of nanoscale HfO2 memristors integrated on 180 nm CMOS wafers is discussed.

Graphdiyne as a Hole‐Transport Channel in Carbon Nitride Heterojunctions for Synergistic CO2 Reduction and γ‐Butyrolactone Synthesis

Angewandte Chemie, EarlyView.
A fully metal‐free heterojunction constructed from graphdiyne (GDY) and polymeric carbon nitride (PCN) enables efficient coupling of CO2 reduction and tetrahydrofuran oxidation. GDY serves as a hole‐transport channel, establishing a built‐in electric field that drives spatial charge separation. The optimized catalyst achieves near‐unity selectivity for

Automated generative process synthesis via transformer‐based dual‐loop simulation and optimization

AIChE Journal, EarlyView.
Abstract This study presents a novel framework for automated generative process synthesis, addressing the complexity of simultaneously optimizing discrete topologies and continuous operating variables. To overcome conventional superstructure limitations, we propose a dual‐loop architecture integrating generative transformers with rigorous process ...
