Accelerating Surface Composition Characterization of Thin‐Film Materials Libraries Using Multi‐Output Gaussian Process Regression

open access: yesAdvanced Intelligent Discovery, EarlyView.
To integrate surface analysis into materials discovery workflows, Gaussian process regression is used to accurately predict surface compositions from rapidly acquired volume composition data (obtained by energy‐dispersive X‐ray spectroscopy), drastically reducing the number of required surface measurements on thin‐film materials libraries.

Robot‐Assisted Measurement of the Critical Micelle Concentration

open access: yesAdvanced Intelligent Systems, Volume 7, Issue 3, March 2025.
The study introduces (SIMO) smart integrator for manual operations, a robotic platform for precise, repeatable determination of (CMC) critical micelle concentration in surfactants. SIMO reduces standard deviation by 80% compared to manual methods. Surfactant, dye, and diluent selection, robotic protocols, and data handling are detailed.

Desymmetrization of Malonic Monoesters and Malonic Acids via Enantioselective Catalytic C(sp3)─H Oxidation

open access: yesAngewandte Chemie, EarlyView.
Manganese‐catalyzed enantioselective C(sp3)─H lactonization with hydrogen peroxide enables the direct desymmetrization of malonic monoesters and malonic acids, providing highly enantioenriched γ‐ and δ‐lactones (up to >99% ee) ABSTRACT Malonate derivatives are readily available starting materials widely employed in the synthesis of bioactive compounds.

Thermometric Based‐Microswimmers with Chemical and Optical Engines

open access: yesAdvanced Intelligent Systems, EarlyView.
Temperature sensing at small scales is typically performed using passive luminescent particles. Here, an alternative approach is demonstrated by integrating upconversion thermometry into self‐propelled microswimmers powered by chemical fuels or light. This strategy offers a step toward dynamic thermal sensing at the microscale, relevant to both lab‐on ...

Microrobotic Catheterization of the Ophthalmic Artery for Targeted Treatment of Retinoblastoma

open access: yesAdvanced Intelligent Systems, EarlyView.
A microrobotic platform is presented that allows teleoperated and autonomous navigation of flow‐driven magnetic microcatheters, MagFlow, into the ophthalmic artery for superselective intra‐arterial infusion of chemotherapy to treat retinoblastoma. Extensive benchtop validations with patient‐derived biomimetic phantoms under optical and fluoroscopic ...

Two‐Nanosensor Electrochemical Profiling of Catecholamine Vesicle Interactions With Acute and Chronic Stress Granules in Living Cells

open access: yesAngewandte Chemie, EarlyView.
A two‐nanosensor electrochemical strategy quantitatively distinguishes reactive oxygen species (ROS) in stress granules (SGs) from catecholamines in vesicles inside living cells. Chronic SGs formed under prolonged stress show elevated ROS and slower release, consistent with SG aging, and promote neurotransmitter loading likely through vesicle fusion ...
