A Self‐Healing Permanent Magnet Putty for Soft Robot Skins With Force Sensing and Functional Recovery

open access: yesAdvanced Robotics Research, EarlyView.
Permanent magnet putty (PMP) integrates high‐coercivity NdFeB particles with a dynamic polyborosiloxane–Ecoflex matrix, achieving rapid self‐healing (90% mechanical recovery in 10 s) and magnetic recovery within 20 min. With twice the sensitivity of commercial putties, PMP enables precise 5–30 N force detection and discrimination between pressing and ...

The Making of an Integrated National Grain Market in China [PDF]

open access: yes, 2001
A market economy will not emerge from a redistributive economy automatically once the state abolishes a redistributive system. Because of the cognitive incompleteness of market actors in post-redistributive societies, and also because of the conflicts ...

Synergistic Ion Transport and Spatial Confinement in Sb‐Embedded Hollow Carbon Nanofibers for Stable Na Metal Anodes

open access: yesAdvanced Science, EarlyView.
This work presents a 3D Sb‐embedded hollow carbon nanofiber (Sb@HCF) host for ultra‐stable Na metal anodes. Experimental analyses and theoretical simulations clearly uncovers that in situ formed Na‐Sb alloy guides uniform Na deposition and serves as efficient ion transport highways. The Sb@HCF‐based cells achieve exceptional cycling stability in half‐,

The People\u27s Republic of China\u27s Potential Growth Rate: The Long-Run Constraints [PDF]

open access: yes, 2014
We estimate the People’s Republic of China’s (PRC’s) potential growth rate in 2012 at 8.7% and at 9.2% for the average of 2008–2012, about the same as the average actual growth rate for this period. This rate is the natural growth rate, that is, the rate

Engineering Approaches to Modify Immunomodulatory Functions of Mesenchymal Stromal Cells (MSCs): Tissue Regeneration and Clinical Application

open access: yesAdvanced Science, EarlyView.
Mesenchymal stromal cells (MSCs) show promise for treating immune‐related disorders through immunomodulation and tissue regeneration. This review gives a brief overview of current clinical approval of MSC therapies. It also discussed how bioengineering, including genetic modification, biomaterial delivery, extracellular vesicles, and iPSC‐derived MSCs,
