2D materials

Professors Kenneth Liechti and Rui Huang in the Department of Aerospace Engineering and Engineering Mechanics at the University of Texas Austin have an opening for a Postdoctoral Fellow to engage in a funded project in the area of multilayered van der Waals materials. Although the project involves both experiments and modeling, the thrust of this position will be experimental. Accordingly, we seek a creative individual who has prior experience in conducting nanomechanical experiments with 2D materials.

Abstract

Two postdoc positions in computational science are available at UIUC in the research group of Prof. Harley T. Johnson in the Department of Mechanical Science and Engineering and the Materials Research Lab.  

Dear Colleagues

I would like to share with you our recent work published on Journal of the Mechanics and Physics of Solids.

Abstract

Dear colleagues, I'd like to share our recent work on blister testing of multilayer 2D materials that gives a direct measurement of Young's modulus and bending rigidity of a multilayer (~10-70 layers). Materials involved include graphene, MoS2, and hBN.

Published in Extreme Mechanics Letters: https://doi.org/10.1016/j.eml.2019.100507. For more than half a century, physicists rejected the existence of two-dimensional (2D) materials since they theoretically underestimated the stability. However, the discovery of one-atom-thick graphene proved the inapplicability of this theory.

 Dear Colleagues, 

Please consider submitting your abstract to our mini-symposium on "Mechanics of deformable atomically-thin materials (Symposium 8.2)" at the 56th Annual Technical Meeting of the Society of Engineering Science (SES), Washington University in St. Louis, October 13-15, 2019. 

https://doi.org/10.1002/adma.201805665 Computational modeling and simulations play an integral role in the bottom‐up design and characterization of graph‐n‐yne materials. Here, the state of the art in modeling α‐, β‐, γ‐, δ‐, and 6,6,12‐graphyne nanosheets for synthesizing graph‐2‐yne materials and 3D architectures thereof is discussed.

In this paper, we experimentally characterize a simple and unified power law for the profiles of a variety of nanobubbles and nanotents formed by 2D materials such as graphene and MoS2 layers. https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.121.266101

ABSTRACT

Dear colleagues, 

We invite you to present your research work at the mini-symposium - "Mechanics and Physics of 2D Crystalline Materials" (Session ID: 1203) at the World Congress on Computational Mechanics (WCCM XIII) in New York City from July 22-27th, 2018.

Element sulfur in nature is an insulating solid. While it has been tested that one-dimensional sulfur chain is metallic and conducting, the investigation on two-dimensional sulfur remains elusive. We report that molybdenum disulfide layers are able to serve as the nanotemplate to facilitate the formation of two-dimensional sulfur.

Two PhD students will be engaged in a research project of National Science Centre (NCN) carried out in the Institute of Fundamental Technological Research PAS, Poland on 'Intelligent design of 2D nanostructures based on molybdenum'.  The materials with a 2D atomic structure (flat, one layer) have drawn attention of researchers for years.

Position Description: 

A research scientist/postdoctoral associate position in the area of synthesis and characterization of 2D materials and nanocomposites is available at Rice University. The successful candidates will work in a highly inter-disciplinary and stimulating environment.

Job Duties and Responsibilities: 

A special issue of Journal of Nanomaterials is devoted to "Low-Dimensional Phase Transforming Materials" which obtained significant interests in the recent years. This topic covers a broad range of research such as

We would like to invite you to submit abstracts to the symposium of Mechanics of Multifunctional 2D materials and 2D-based Nanostructures at the 53rd Annual Technical Meeting of the Society of Engineering Science (SES 2016) to be held at University of Maryland College Park (October 2-5, 2016).

Symposium Description

Two-Dimensional (2D) materials have been widely studied since the discovery of graphene in 2004.  Many of the initial works on the various 2D materials (graphene, MoS2 and other transition metal dichalcogenides, black phosphorus, and others like the monochalcogenides) by mechanicians focused on issues like ideal strength, and appropriate methods to calculate the bending modulus.  Some of these, and other issues, were reviewed by Sulin Zhang in a J-Club from March 2015 (http://imechanica
