Mehmet Kanik,Sirma Orguc,Georgios Varnavides,Georgios Varnavides,Jinwoo Kim,Thomas Benavides,Dani Gonzalez,Timothy Akintilo,Cemal Cem Tasan,Anantha P. Chandrakasan,Yoel Fink,Polina Anikeeva +11 more
TL;DR: A high-throughput iterative fiber-drawing technique was applied to create strain-programmable artificial muscles with dimensions spanning three orders of magnitude that are thermally and optically controllable, can lift more than 650 times their own weight, and withstand strains of >1000%.
Journal ArticleDOI

Uri Vool,Assaf Hamo,Georgios Varnavides,Georgios Varnavides,Yaxian Wang,Tony X. Zhou,Tony X. Zhou,Nitesh Kumar,Yuliya Dovzhenko,Ziwei Qiu,Christina A. C. Garcia,Andrew T. Pierce,Johannes Gooth,Johannes Gooth,Johannes Gooth,Polina Anikeeva,Claudia Felser,Claudia Felser,Prineha Narang,Amir Yacoby +19 more
TL;DR: In this paper, the spatial current profile within three-dimensional tungsten ditelluride was analyzed and it was shown that it exhibits non-uniform current density, indicating hydrodynamic flow.
Journal ArticleDOI
Remotely controlled chemomagnetic modulation of targeted neural circuits.
Siyuan Rao,Ritchie Chen,Ava A. LaRocca,Michael G. Christiansen,Michael G. Christiansen,Alexander W. Senko,Cindy H. Shi,Po Han Chiang,Georgios Varnavides,Georgios Varnavides,Jian Xue,Yang Zhou,Yang Zhou,Seongjun Park,Ruihua Ding,Junsang Moon,Guoping Feng,Guoping Feng,Polina Anikeeva +18 more
TL;DR: A remotely controlled chemomagnetic modulation—a nanomaterials-based technique that permits the pharmacological interrogation of targeted neural populations in freely moving subjects and activates endogenous circuits by enabling the regulated release of receptor ligands.
Journal ArticleDOI
Fundamental aspects to localize self-catalyzed III-V nanowires on silicon.
Jelena Vukajlovic-Plestina,Wonjong Kim,L. Ghisalberti,L. Ghisalberti,Georgios Varnavides,Gözde Tütüncüoglu,Heidi Potts,Martin Friedl,Lucas Güniat,W. C. Carter,W. C. Carter,Vladimir G. Dubrovskii,A. Fontcuberta i Morral +12 more
TL;DR: A mechanism to explain self-catalyzed III-V nanowires growth on silicon is proposed, providing valuable insights for growing high yield nanowire arrays and clear grounds for realistic integration of III-Vs on silicon and for the organized growth of Nanowires in other material systems.
Journal ArticleDOI
