Three‐Channel Electron Engineered Fe‐88A@CeO2/CDs Nanozyme with Enhanced Oxidase‐Like Activity for Efficient Biomimetic Catalysis

open access: yesAdvanced Science, EarlyView.
xx xx. Abstract Iron‐based metal‐organic framework (MOF) nanozymes have garnered considerable attention owing to a large specific surface area, adjustable porosity, large Fe‐O clusters, and unsaturated Fe sites. However, the sluggish charge‐transfer rate and restricted active sites of the nanozymes lead to poor enzyme‐like activity and further impede ...

Fundamentals and Perspectives on Materials for Bifunctional Electrocatalysis

open access: yesAdvanced Science, EarlyView.
This review presents a comparative evaluation of key catalyst families for HER and OER, including MOFs, metal oxides, hydroxides/hydrides, carbon‐based materials, phosphides, and chalcogenides. Their electrochemical activity, stability, and commercialization potential are critically analyzed, with design strategies for hybrid catalysts also discussed ...

Clinically Informed Intelligent Classification of Ovarian Cancer Cells by Label‐Free Holographic Imaging Flow Cytometry

open access: yesAdvanced Intelligent Systems, Volume 7, Issue 3, March 2025.
Quantitative phase maps of single cells recorded in flow cytometry modality feed a hierarchical architecture of machine learning models for the label‐free identification of subtypes of ovarian cancer. The employment of a priori clinical information improves the classification performance, thus emulating the clinical application of liquid biopsy during ...

Printed Zinc Tin Oxide Memristors for Reservoir Computing

open access: yesAdvanced Intelligent Systems, EarlyView.
Fully patterned zinc tin oxide memristors produced mostly with printing techniques that is programmed for physical reservoir computing. MNIST handwriting dataset is used to program the memristor and a 4‐bit and a 5‐bit cell. In this work, fully patterned zinc tin oxide (ZTO) memristors are introduced using inkjet printing.

The mechanism of anaphase spindle elongation: uncoupling of tubulin incorporation and microtubule sliding during in vitro spindle reactivation. [PDF]

open access: yes, 1988
To study tubulin polymerization and microtubule sliding during spindle elongation in vitro, we developed a method of uncoupling the two processes. When isolated diatom spindles were incubated with biotinylated tubulin (biot-tb) without ATP, biot-tb was ...

Custom Shape Formation in Continuum Robots Using Compliant Bistable Segments for Medical Applications

open access: yesAdvanced Intelligent Systems, EarlyView.
This article describes the integration of compliant bi‐stability in continuum robots. This integration leads to two variants of compliant bistable mechanism (CBM) integrated continuum robot segments, extending and locking. Results show that when used together, these CBM‐integrated segments allow the continuum robot to form custom shapes.
