Nanoparticles: strained and stiff.
Nanoparticles may contain unusual forms of structural disorder that can substantially modify materials properties and thus cannot solely be considered as small pieces of bulk material. We have developed a method to quantify intermediate-range order in 3.4-nanometer-diameter zinc sulfide nanoparticles and show that structural coherence is lost over distances beyond 2 nanometers. The zinc-sulfur ...
متن کاملWrinkling of a stiff thin film bonded to a pre-strained, compliant substrate with finite thickness.
A stiff thin film bonded to a pre-strained, compliant substrate wrinkles into a sinusoidal form upon release of the pre-strain. Many analytical models developed for the critical pre-strain for wrinkling assume that the substrate is semi-infinite. This critical pre-strain is actually much smaller than that for a substrate with finite thickness (Ma Y et al. 2016 Adv. Funct. Mater. (doi:10.1002/ad...
متن کاملBuckling of a stiff thin film on a pre-strained bi-layer substrate
Controlled buckling can impart stretchable mechanics to brittle materials when integrated as thin films on soft, elastomeric substrates. Typical elastomers are permeable to fluids, however, and therefor unable to provide robust barriers to entry of water, for instance, into devices built with the supported thin films. In addition, the mechanical strength of a system dominated by a soft substrat...

متن کاملFever and stiff neck.
Clinical Presentation: An 11-month-old boy was seen in the emergency department by his pediatrician for evaluation of fever (body temperature, 38.5°C) and a stiff neck. The patient’s illness began 5 days earlier when he developed nasal congestion and fever. His pediatrician prescribed amoxicillin on the third day of illness. The fever persisted, however, and by the fifth day, the patient was ir...
