Thermo-Reversible Gelation Of Rod-Coil and Coil-Rod-Coil Molecules Based on Perylene Diimides
… sides of the PDI (PS-PTCDI-PS), to form a coil-rod-coil molecule, and studied its gelation behavior. This differs from the case of coil-rod-coil molecules discussed before; with Di-PDMS, the Tg of the PDMS segment is -125 °C. With DJ-PTCDI, considering that the glass transition temperatures of …

Binary mixtures of rod-like colloids
… the mixture. Specializing to binary mixtures of rod-like particles, these functionals are then used to explore the stability of isotropic and nematic equilibrium phases in terms of composition and rod lengths. We extend the description to consider non-equilibrium phenomena by combining our …

Design of a smart fishing rod
… popularity, the technology of the fishing rods has remained stagnant. This was something that the startup company Nordic Angling sought to fix by introducing the internet of things to the realm of fishing. This was to be done by designing the worlds first Smartrod, which is the subject of …

Computer simulation of rod-sphere mixtures.
… adding small spherical particles to a fluid of rods which would otherwise represent a liquid crystalline (LC) substance. Firstly, a bulk mixture of Hard Gaussian Overlap particles with an aspect ratio of 3:1 and hard spheres with diameters equal to the breadth of the rods is simulated at various …

Dynamics of rod-coil block copolymers
… assemblies of different geometries introduce many interesting new phenomena such as entropic packing and liquid crystalline interactions, dynamic effects are also important to understand for optimal design of material mechanics, processing kinetics, and the new physics that directly …

Spectral analysis for rod formation dynamics
This thesis deals with the production of a continuous rod of non-uniform properties which is formed by wrapping fibers with a thin membrane. This rod is driven axially and cut into segments. Measurements of pressure, temperature, axial force, axial velocity, horizontal and vertical displacements …

Stability of long multiple-rod constructs and dual-rod constructs in the thoracic spine: a biomechanical cadaveric study
… spinal deformity is typically performed with a 2-rod construct spanning the targeted area of fusion. More evidence is starting to emerge around the utility of multiple-rod constructs (typically 3 or more rods) to increase the stiffness and stability of a spinal fusion construct. Much of this work …

cis-Regulation in the Mammalian Rod Photoreceptor
… dual regulation of a single binding site can produce diverse gene expression patterns. I conclude that simple <italic>cis</italic>-regulatory elements can produce complex expression outputs due to interactions between transcriptional activators and detailed quantitative models will be necessary …

Analysis of hairy-rod polyimides for photoalignment
… the majority of the in-house synthesised hairy-rod polyimides (PIs). Oblique unpolarised UV irradiation of branched PIs results in pretilted LCs of 2 deg to 88 deg depending on chemical composition, processing history and fluence. The initial pretilted alignment collapsed to homogeneous …

Geometrically nonlinear configurations in rod-like structures
Rod-like structures are ubiquitous in both nature (e.g. bacterial flagella) and engineering (ropes, cables, pipelines, and Carbon nanotubes), from nanometer to kilometer scale, and often undergo geometrically nonlinear deformation. Due to the slender geometry of the structures, the material strain …

Super-collimation in a rod-based photonic crystal
… the design, fabrication, and characterizion of a rod-based two-dimensional photonic crystal super-collimator. The dispersion contours for the photonic crystal are simulated as part of the design process. Two different fabrication process methods are developed and applied. The super-collimator s …

Controlled ablation of rod photoreceptors in transgenic Xenopus laevis
… eye. Loss of a certain group of neurons called rod photoreceptors can occur as the result of genetic mutation. In humans, and in mammalian models of retinal degeneration, the death of these cells is permanent, and often followed by cone photoreceptor death, which leads to blindness. As a step …

Downhole Gas Separator Performance in Sucker Rod Pumping System
Volumetric efficiency of a sucker rod pump has been a major concern for artificial lift designers for a long time. One way to reduce the amount of gas entering into the pump is to use downhole gas separators. The main purpose of these devices is to facilitate agglomeration of gas bubbles so that …

Molecular Dissection of Multifunctional Proteins in Rod Outer Segments
<p>Rod photoreceptors are specialized neurons responsible for capturing photons and translating visual information into electrical signals. Visual signal transduction in rods is confined to the unique outer segment organelle, a modified primary cilium consisting of a stack of hundreds of flattened …
