Temperature‐Dependent Properties of Amino‐As Based InAs/ZnSe Core‐Shell Quantum Dot Films
Advanced Optical Materials, EarlyView.InAs colloidal quantum dots (CQDs) exhibit tunable optical bandgap covering the near‐infrared spectrum, making them attractive for various optoelectronicapplications. This work demonstrates that their optical properties are partially maintained up to 250°C, where Atomic Force Microscopy (AFM) and Kelvin Probe Force Microscopy (KPFM) measurements reveal

Information Transmission Strategies for Self‐Organized Robotic Aggregation
Advanced Robotics Research, EarlyView.In this review, we discuss how information transmission influences the neighbor‐based self‐organized aggregation of swarm robots. We focus specifically on local interactions regarding information transfer and categorize previous studies based on the functions of the information exchanged.

Characteristics of Cherenkov Radiation in Naturally Occuring Ice
, 2016 We revisit the theory of Cherenkov radiation in uniaxial crystals. Historically, a number of flawed attempts have been made at explaining this radiation phenomenon and a consistent error-free description is nowhere available.

MELEGROS: Monolithic Elephant‐Inspired Gripper with Optical Sensors
Advanced Science, EarlyView.MELEGROS is a monolithic, elephant‐inspired soft gripper integrating 3D‐printed optical sensors within a pneumatically actuated lattice. Simulation‐guided design decouples tactile and proprioceptive sensing. Characterized through grasping tests, MELEGROS can reach, scoop, and grasp, showcasing a paradigm where fully embedded sensing and continuous ...

Encoding Cumulation to Learn Perturbative Nonlinear Oscillatory Dynamics
Advanced Science, EarlyView.Weak nonlinearities critically shape the long term behavior of oscillatory systems but are difficult to identify from data. A data‐driven framework is introduced to infer governing equations of weakly nonlinear oscillators from sparse and noisy observations.
