Prolate and oblate chiral liquid crystal spheroids (open access)

Prolate and oblate chiral liquid crystal spheroids

Article examining the palette of morphologies that arises when microdroplets are deformed into nonspherical shapes in a controllable manner. Specifically, geometrical confinement and mechanical strain are used to manipulate orientational order, phase transitions, and topological defects that arise in chiral liquid crystal droplets. The reported structures and assemblies offer potential for applications in smart coatings, smart fabrics, and wearable sensors.

A Critical Review of Laser Shock Peening of Aircraft Engine Components (open access)

A Critical Review of Laser Shock Peening of Aircraft Engine Components

Article describes how many aviation accidents are caused by the failure of aircraft engine components, and engine blades are especially vulnerable to high-cycle fatigue fracture in severe working environments as well as to impact damage caused by foreign objects. This review provides an overview of the development of LSP for use in treating aircraft engine components over the past three decades, with a brief introduction to the development of high-energy pulsed lasers for LSP.

Quantitative estimation of closed cell porosity in low density ceramic composites using X-ray microtomography (open access)

Quantitative estimation of closed cell porosity in low density ceramic composites using X-ray microtomography

Article asserts that x-ray Microtomography is a proven tool for phase fraction analysis of multi-phase systems, provided that each phase is adequately partitioned by some means of data processing. The authors present a novel, combined methodology for accurate porosity analysis—despite these shortcomings.
