Delamination Mechanics of Carbon Nanotube Micropillars.

The adhesion of carbon nanotube (CNT) forests to their growth substrate is a critical concern for many applications. Here, we measured the delamination force of CNT forest micropillars using in situ scanning electron microscopy (SEM) tensile testing. A flat tip with epoxy adhesive first established contact with the top surface of freestanding CNT pillars and then pulled the pillars in displacement-controlled tension until delamination was observed.

Precision Milling of Carbon Nanotube Forests Using Low Pressure Scanning Electron Microscopy.

A nanoscale fabrication technique appropriate for milling carbon nanotube (CNT) forests is described. The technique utilizes an environmental scanning electron microscope (ESEM) operating with a low pressure water vapor ambient. In this technique, a portion of the electron beam interacts with the water vapor in the vicinity of the CNT sample, dissociating the water molecules into hydroxyl radicals and other species by radiolysis.

Diamond burr debridement vs. grid keratotomy in canine SCCED with scanning electron microscopy diamond burr tip analysis.

Objectives: (i) Compare the outcome of canine SCCED treated with grid keratotomy (GK) or diamond burr debridement (DBD); (ii) Serially evaluate morphologic and elemental composition changes to diamond burr tips.

Animals Studied: A total of 91 eyes of 88 canine SCCED patients treated at the University of Missouri (2005-2015); 75 fresh cadaver porcine globes.

Procedures: (i) Medical records were reviewed retrospectively.

What all nurses need to know about Stickler syndrome.

Stickler syndrome is one of the most common clinical syndromes in Europe although it is also one of the least known and consequently most misidentified. Because Stickler syndrome affects connective tissue, many different symptoms present, from vision to mobility difficulties. This article examines the main symptoms of the syndrome and includes an insightful personal account showing how it affects the whole family.
