Abstract Cryo-transmission electron microscopy (cryo-EM) of frozen hydrated specimens is an efficient method for the structural analysis of purified biological molecules. However, cryo-EM and cryo-electron tomography are limited by the low signal-to-

Abstract High-density phase change memory (PCM) storage is proposed for materials with multiple intermediate resistance states, which have been observed in 1T-TaS2 due to charge density wave (CDW) phase transitions. However, the metastability respons

Defect contrast with 4D-STEM: Understanding crystalline order with virtual detectors and beam modification

Autor: Stephanie M Ribet, Colin Ophus, Roberto dos Reis, Vinayak P Dravid

Material properties strongly depend on the nature and concentration of defects. Characterizing these features may require nano- to atomic-scale resolution to establish structure-property relationships. 4D-STEM, a technique where diffraction patterns

Spatial Mapping of Electrostatic Fields in 2D Heterostructures

Autor: Nathaniel P. Stern, Akshay A. Murthy, Roberto dos Reis, Takashi Taniguchi, Vinayak P. Dravid, Teodor K. Stanev, Stephanie M. Ribet, Kenji Watanabe, Pufan Liu

Publikováno v: Nano Lett

In situ electron microscopy is an effective tool for understanding the mechanisms driving novel phenomena in 2D structures. However, due to practical challenges, it is difficult to address these technologically relevant 2D heterostructures with elect

Degeneration Behavior of Cu Nanowires under Carbon Dioxide Environment: An In Situ/Operando Study

Autor: Kyoungdoc Kim, Paul J. M. Smeets, Cesar Villa, Kun He, Roberto dos Reis, Xiaobing Hu, Stephanie M. Ribet, Vinayak P. Dravid, Peter W. Voorhees

Publikováno v: Nano Letters. 21:6813-6819

Copper (Cu) is a catalyst broadly used in industry for hydrogenation of carbon dioxide, which has broad implications for environmental sustainability. An accurate understanding of the degeneration behavior of Cu catalysts under operando conditions is
