Layered and scrolled nanocomposites with aligned semi-infinite graphene inclusions at the platelet limit, Liu, et al. Strano, Science, 2016
Novelty/impact/significance:
A stacking and folding method (semi-infinite graphene/polycarbonate (Gr/PC) films, exponential increase in thickness with quadrant fold) to generate aligned Gr/PC composites (~320 layers) that have superior modulus and strength at exceptionally low volume fraction of Gr.

Your suggestions and feedback will make the videos better.
Thanks.
We have edited a new book on 2D materials. Thanks to all the authors for their contribution.

It is with great pleasure that we announce the outcome of the 2020 competition for the Eshelby Mechanics Award for Young Faculty. The recipient of the 2020 award is Professor Shuman Xia, from Georgia Tech. This award is given annually to rapidly emerging junior faculty who exemplify the creative use and development of mechanics. The intent of the award is to promote the field of mechanics, especially among young researchers.
Metamaterials can provide many engineering applications such as vibration attenuation and heat flux cloaking. However, the problems of isolating elastic waves and directing heat flux via a metamaterial device have not been resolved completely yet. In this paper, a dual-functional metamaterial, with cylindrical stub periodically attached on the multilayered plate, is initially designed and investigated numerically and experimentally. Numerical results demonstrate that the elastic wave band gaps can be opened and tuned effectively with the evolution of the rotation angle of the matrix plate.
The protection efficacy of facemasks and respirators has been well documented. The change of human nasal functions after wearing N95 respirator and surgical facemask is not known. In a parallel group study, we recruited 87 healthy healthcare workers. Each of the volunteers attended two sessions, and wore N95 respirator in session 1 (S1) and surgical facemask in session 2 (S2) for 3hours. Mean minimum cross sectional area (mMCA) of the two nasal airways via acoustic rhinometry and nasal resistance via rhinomanometry were measured before and immediately after the mask wearing.
Face masks or respirators are commonly worn by medical professionals and patients for protection against respiratory tract infection and the spread of illnesses, such as severe acute respiratory syndrome and pandemic influenza (H1N1). Breathing discomfort due to increased breathing resistance is known to be a problem with the use of N95 respirators but there is a lack of scientific data to quantify this effect. The purpose of this study was to assess objectively the impact of wearing N95 face masks on breathing resistance.
