Intelligent Soft Opto‐Magnetic Robot for Minimally Invasive Interventional Therapy
Advanced Science, EarlyView.An intelligent soft opto‐magnetic (iSOM) robot is developed that integrates remote magnetic actuation, skin‐mimic tactile perception, and photothermal ablation in a near‐millimeter‐scale design. It enables precise intraluminal navigation and localized ablation while providing real‐time optical feedback to support safe and accurate minimally invasive ...

Combining the Pitcher and Lotus Plant: Supericephobic and Superhydrophobic Silicone Films
Advanced Science, EarlyView.Based on bench‐top nanomolding of polydimethylsiloxane (PDMS) with optimized silicone oil content, we developed hierarchically structured silicone films by essentially combining the properties of the lotus and pitcher plant; particularly we are able to achieve water contact angle as high as 171° and ice adhesion strength as low as 11.5 kPa (i.e ...

Advanced Science, EarlyView.Ferroelectric phase stability in Hf₀.5Zr₀.5O2 films is enhanced by confinement to the (111) crystal orientation, as demonstrated by first‐principles calculations and experiments. Polarization approaching its maximum value is achieved through selective ferroelectric switching paths, which are further tuned by oxygen vacancies and cation doping to ...
