Source: Shreyas Narsipur, Mechanical and Aerospace Engineering, North Carolina State University, Raleigh, NC A propeller is a twisted airfoil, where the angle of the chord changes with respect to the location, along the radial station, as shown in Figure 1. Propellers are widely used in aircraft and watercraft propulsion systems thereby necessitating detailed characterizations of propellers to design high performance vehicles. Figure 1. Chord, thickness, and pitch at a radial station. One of...

Solid-state Graft Copolymer Electrolytes for Lithium Battery Applications
0 Views •
2013
Lithium ion batteries employ flammable and volatile organic electrolytes that are suitable for ambient temperature applications. A safer alternative to organic electrolytes are solid polymer batteries. Solid polymer batteries operate safely at high temperatures (>120 °C), thus making them applicable to high temperature applications such as deep oil drilling and hybrid electric vehicles. This paper will discuss (a) the polymer synthesis, (b) the polymer conduction mechanism, and (c) provide...

Use of zebrafish for cardiovascular research is expanding towards research on adult hearts. For these applications, quick and simple isolation of cardiac tissues is key to avoid post-mortem changes and to obtain an adequate number of samples. Here, we describe a fast and reproducible method for dissecting adult zebrafish hearts.
FAQs
These variables jointly influence how much material remains on the substrate and how evenly it is distributed. The blade gap sets the available spacing, movement speed affects spreading, and viscosity governs how the liquid, slurry, or polymer mixture flows. Controlling them together helps researchers obtain a reproducible film thickness and structure.
Drying conditions help determine the final thickness and structure of the deposited film after spreading. Consequently, a coating with the same starting material and blade settings may not produce the same experimental surface if its drying environment changes. Monitoring this stage is important when preparing reproducible biomaterial coatings, culture surfaces, or scaffold components for biological studies.
A defined blade height establishes a controlled space between blade and substrate during spreading. That spacing contributes to control over the deposited layer, while changes can influence the resulting thickness and structure. Maintaining the selected height is therefore important when comparing coatings or fabricating culture and scaffold surfaces intended for repeatable developmental biology experiments.
Begin with a flat substrate and a selected liquid, slurry, or polymer mixture. Set the blade height and movement speed, spread the material across the surface, and then control the drying conditions. The resulting layer can be assessed through its thickness and structure before use as a coating, culture surface, or scaffold component.
It can create biomaterial coatings, cell-culture surfaces, and scaffold components that provide defined physical environments for biological experiments. These platforms support studies of how such environments influence cell attachment, organization, and differentiation. The approach also contributes to tissue-engineering experiments and models of developmental processes by making the underlying material surface more reproducible.
Reproducible coatings support repeated fabrication of experimental platforms with more consistent material surfaces. In developmental biology, these platforms can be used to examine cell attachment, organization, and differentiation under physical environments produced through the coating process. The same consistency is valuable for tissue-engineering studies and models of developmental processes, where comparable surfaces support meaningful experimental comparisons.
