Topological Point Defects in SmC* Liquid Crystals Under Mechanical Disturbance
Advanced Materials Interfaces, EarlyView.Tangetial air jet shear inducess island formation and nucleates topological point defects in uniform SmC films. Island bounded by edge dislocation loops shrink and transform into isolated point defects under continued shear. Mechanical perturbatio provides a controllable route for defect engineering in smectric liquid crystal thin films.

Applications of Various Methods of Analysis to Combustion Instabilities in Solid Propellant Rockets [PDF]
, 1996 Instabilities of motions in a combustion chamber are consequences of the coupled dynamics of combustion processes and of the flow in the chamber. The extreme complexities of the problem always require approximations of various sorts to make progress in

Hierarchical Structure and Fabrication of Functionally Graded Biointerfaces in the Mussel Byssus
Advanced Materials Interfaces, EarlyView.The byssus is a fibrous protein‐based holdfast consisting of mechanically distinct interfaces, which mussels use to anchor their soft living tissue to hard seashore surfaces. Here, multiscale methodologies were used to elucidate the compositional and structural features underlying these functionally graded interfaces and how they are fabricated through

A new fluorescent probe based on BODIPY for testing NO2 released from propellants
Energetic Materials FrontiersAfter long-term storage, solid propellants often exhibit various aging characteristics. This study presents a strategy for assessing the state of propellants using the Boron-dipyrrole Ni complex (BDP-Ni) as a probe.
