TL;DR: It is shown that the blister defect is seldom found in isolation and is more commonly coupled with dislocations where it can act as an intermediate state, permitting dislocation core climb without the atom ejection from the graphene lattice required for nonconservative motion.
Abstract: Using 80 kV electron beam irradiation we have created graphene blister defects of additional carbon atoms incorporated into a graphene lattice. These structures are the antithesis of the vacancy defect with blister defects observed to contain up to six additional carbon atoms. We present aberration-corrected transmission electron microscopy data demonstrating the formation of a blister from an existing divacancy, together with further examples that undergo reconfiguration and annihilation under the electron beam. The relative stability of the observed variations of blister are discussed and considered in the context of previous calculations. It is shown that the blister defect is seldom found in isolation and is more commonly coupled with dislocations where it can act as an intermediate state, permitting dislocation core climb without the atom ejection from the graphene lattice required for nonconservative motion.

TL;DR: A bandage containing a new technology demonstrated the lowest surface coefficient of friction of any bandage tested, and clinical tests performed with the same bandage demonstrated significant reduction of the coefficient ofriction on the skin.

TL;DR: In this paper, the impedance measurements on these artificial blisters led to an extension of the mechanistic model for cathodic delamination and the conclusion can be drawn that characterisation of the anodic and cathodic regions in blisters is not possible with EIS, however, the impedance characteristics of the corrosion product in the defect can be investigated.

TL;DR: A universal morphological feature of telephone cord blisters characterized by their sequential sectional profiles exhibiting a butterfly shape is reported using atomic force microscopy.
Abstract: Formation of telephone cord blisters as a result of buckling delamination is widely observed in many compressed film-substrate systems. Here we report a universal morphological feature of such blisters characterized by their sequential sectional profiles exhibiting a butterfly shape using atomic force microscopy. Two kinds of buckle morphologies, light and heavy telephone cord blisters, are observed and differentiated by measurable geometrical parameters. Based on the Foppl-von Karman plate theory, the observed three-dimensional features of the telephone cord blister are predicted by the proposed approximate analytical model and simulation. The latter further replicates growth and coalescence of the telephone cord into complex buckling delamination patterns observed in the experiment. Telephone cord blisters constitute a well-known example of patterns generated following buckling in thin films. Here the authors develop an analytical approach that can model the sectional height profiles along the blisters that they measure experimentally and simulate numerically.

TL;DR: In this article, a double metal gate of Pd/Pt was proposed to avoid the hydrogen-induced lattice expansion of the Pd film without any loss of the hydrogen sensitivity.
Abstract: Blister formation in palladium gate MISFET hydrogen sensors occurs even at low hydrogen pressures and the sensors fail in long-time operation. The blisters in the Pd gate are due to hydrogen-induced lattice expansion of the Pd film. By making a double metal gate of Pd/Pt, the problem is avoided without any loss of the hydrogen sensitivity.
