CPP–PEG‐Guided Surface Engineering of Mitochondria Enables Efficient Cellular Uptake and Respiratory Modulation

Advanced Materials Interfaces, EarlyView.
PEG‐guided mitochondrial surface engineering supports structural stabilization and controlled presentation of cell‐penetrating peptides. CPP–PEG‐modified mitochondria exhibit enhanced cellular uptake and uptake‐associated respiratory modulation, providing a proof‐of‐concept framework for modular organelle engineering and future bioenergetic modulation ...

Dental Microwear Texture Analysis on Radular Teeth

Advanced Materials Interfaces, EarlyView.
3D microwear textures reveal how gastropod radular teeth respond to controlled abrasive contact. Distinct surface signatures distinguish regular abrasion from fracture‐dominated material removal, showing how mineralized coatings, fibrous cores, and substrate properties jointly shape wear and failure in a biological scraping interface.

AI‐Powered Framework for Evaluating Drug Efficacy for Three‐Dimensional In Vitro Cancer Models in Robot‐Assisted Production

Advanced Robotics Research, EarlyView.
An AI‐powered, robot‐assisted framework automatically produces, images, and analyzes 3D tumor spheroids to evaluate drug efficacy. Integrated modules handle spheroid formation, live/dead staining, brightfield imaging, and automated image analysis, including spheroid segmentation, viability and metrics to assess the drug treatment efficacy. The workflow

Improvement of Space Debris Orbits

, 2017
The increasing amount of space debris requires huge efforts for the tracking networks in order to maintain the orbits of all the objects. The precise knowledge of the positions of space debris objects is fundamental for collision avoidance maneuvers performed by satellite operators and for future active debris removal missions.
