Dear iMechanicians,
I want to share our recent work published in Nano Letters on the blister test of nanoflakes. The title, abstract, and links for data are as follows:

Job description for Internship as a Flexible Display Technologist
Job Summary:
In this position, you will play a critical role in developing and assessing new display technologies in for possible use in Apple products, crafting new designs and intellectual property for Apple, and interacting with multiple partners across the company and with technology and product suppliers to Apple.
Key Qualifications:
Wrinkling of thin films under tension is omnipresent in nature and modern industry, a phenomenon which has aroused considerable attention during the past two decades because of its intricate nonlinear behaviors and intriguing morphology changes.
A highly stretched hyperelastic shell exhibits a coupling behavior of local wrinkling and global bending within the stability boundary, and curvature resists and can even suppress surface wrinkles beyond a critical threshold. Here, we report a novel phenomenon that smooth surface maintains upon stretching a soft shell, while wrinkles emerge upon unloading, which implies a nonlinear interplay between curvature and Mullins (stress softening and residual strain) effects in the entire loading-unloading cycle.
Dear iMechanicians, I would like to share our recent work on a drop confined by two adhesive graphene sheets (as illustrated below).
Wrinkling is one of the most important mechanical deformation modes (for example, buckling and crumpling) that are omnipresent in our daily life: for instance, wrinkled fingers after soaking in water for a prolonged time, the folds within the brain, and metal wrinkles after a car collision, to name a few.
Good day, all!
Currently, I'm interested in the conformability of a membrane with a given surface.
Owing to their enormous capacities, Li-S batteries have emerged as a prime candidate for economic and sustainable energy storage. Still, potential mechanics-based issues exist that must be addressed: lithiation of sulfur produces an enormous volume expansion (~80%). In other high capacity electrodes, large expansions generate considerable stresses that can lead to mechanical damage and capacity fading.
