Surface‐Anchored Microgel‐Based Films as Anti‐Icing Coatings
Advanced Materials Interfaces, EarlyView.The microgel‐based anti‐icing coatings presented in this work reduce ice adhesion by up to 90% on various substrates. This effect can be attributed to the incorporated functional cationic moieties binding a lubricating layer of quasi‐liquid interfacial water.

Fabrication of Fibers With Complex Features Using Thermal Drawing of 3D‐Printed Preforms
Advanced Materials Technologies, EarlyView.3D printing enables rapid fabrication of macroscale polymer preforms with complex geometries. Thermal drawing then scales these structures into long fibers while preserving micron‐scale cross‐sectional features. This workflow provides a fast, low‐cost route to functional fibers with tailored geometries and material combinations for catheter, robotic ...

Journal of Transnational American Studies, 2011 This article explores race relations in the provincial city of Cienfuegos, Cuba, during a time of immense political change from 1894 to 1899. In those five years, Cuba was transformed from a Spanish colony struggling for independence to an occupied ...

Racial Fault-lines in “Baseball’s Great Experiment:” Black Perceptions, White Reactions
Transatlantica, 2012 This paper examines three facets of the breaking of major league baseball’s color line by Jackie Robinson of the Brooklyn Dodgers in 1947: the perception of blacks, the response of white players (whether teammates or opponents), and the reaction of ...

Tunable Quasi‐Resonances in Polypyrrole Nanodisks
Advanced Optical Materials, EarlyView.Polaronic carrier absorption enables electrochemically switchable quasi‐resonances in conducting polymer nanoantennas. ABSTRACT Redox‐tunable conducting polymers have emerged as promising materials for dynamic plasmonics and metasurfaces. However, only a few conducting polymers with particularly high conductivities (>1000 S/cm) have been reported to ...

Personal Explorations in the Study of Ethnic and Race Relations
Journal of the Scholarship of Teaching and Learning, 2018 Many have discussed the inherent problems in teaching race and ethnic relations courses. Students often come to class with preconceived ideas about their social world, and a range of feelings and experiences including confusion, biases and misconceptions.

Advanced Robotics Research, EarlyView.A codesign multiobjective optimization framework was developed to enhance the morphology and controller of a snake‐like robot driven by artificial muscles. It improved planar locomotion, agility, and power efficiency. The approach optimized link geometry and controller gains, revealing that shorter muscles near joints and longer linkages maximize ...

Numerical Modeling of Photothermal Self‐Excited Composite Oscillators
Advanced Robotics Research, EarlyView.We present a numerical framework for simulating photothermal self‐excited oscillations. The driving mechanism is elucidated by highlighting the roles of inertia and overshoot, as well as the phase lag between the thermal moment and the oscillation angle, which together construct the feedback loop between the system state and the environmental stimulus.
