Core-Shell Structure

Richard G. Jones, Christopher K. Ober, Philip Hodge et al. · IUPAC Standards Online · 2016

In the past, aggregation and self-assembly have been associated principally with micellar and colloidal systems of molecules; however, with the advent of supramolecular chemistry, molecular self-assembly has been opened to a much wider understanding that has facilitated access to a variety of different shapes and sizes, along with the construction of new and fascinating molecular topologies. This document aims at defining more than 150 terms related to aggregation and self-assembly in the particular case of macromolecules. The list is restricted to the most commonly encountered terms.

Nuclear Shell Structure

M. H. L. Pryce · Proceedings of the Physical Society Section A · 1954

There is convincing evidence from the study of nuclear stabilities, magnetic moments, spins, and from other sources, that there is a marked regularity of nuclear properties, particularly clearly shown by breaks at 2, 8, 20, 28, 50, 82 and 126 protons or neutrons. This is explained in terms of an individual level model of nuclear structure similar to the model used in explaining the periodicity of atomic structure. In nuclei, a strong spin-orbit interaction, of unexplained origin, plays an important part. This model leads to an excellent understanding of nuclear regularities, particularly of spins and magnetic moments. It has severe limitations, however, and, particularly when large shells are filling, it needs to be supplemented by a more `collective' approach to nuclear structure.

Transparent shell structure

Arno Pronk, T.A. van Dooren, J. Hermans · TU/e Research Portal (Eindhoven University of Technology) · 2014

In this paper the connection of double-curved double glass elements with a translucent polymer is described together with a first prototype of a double glass structure with translucent connections without any other additional supporting structure. With this technique, it is possible to make translucent shell structures of double glass elements. In this paper we describe the connections and the testing of these connections on tensile stress.

Polymer Shell Structure

Nathan Scott · Iowa State University Digital Repository (Iowa State University) · 2013

The initial intention of my independent studio was to study how digital design can improve the overall construction process. By understanding the real world constraints and solving structural and material connections, the digital design process will ideally reduce the overall time a project is in construction and solve problems before they occur.

Rib‐reinforced Shell Structure

Wei Li, Anzong Zheng, Lihua You et al. · Computer Graphics Forum · 2017

Abstract Shell structures are extensively used in engineering due to their efficient load‐carrying capacity relative to material volume. However, large‐span shells require additional supporting structures to strengthen fragile regions. The problem of designing optimal stiffeners is therefore becoming a major challenge for shell applications. To address it, we propose a computational framework to design and optimize rib layout on arbitrary shell to improve the overall structural stiffness and mechanical performance. The essential of our method is to place ribs along the principal stress lines which reflect paths of material continuity and indicates trajectories of internal forces. Given a surface and user‐specified external loads, we perform a Finite Element Analysis. Using the resulting principal stress field, we generate a quad‐mesh whose edges align with this cross field. Then we extract an initial rib network from the quad‐mesh. After simplifying rib network by removing ribs with little contribution, we perform a rib flow optimization which allows ribs to swing on surface to further adjust rib distribution. Finally, we optimize rib cross‐section to maximally reduce material usage while achieving certain structural stiffness requirements. We demonstrate that our rib‐reinforced shell structures achieve good static performances. And experimental results by 3D printed objects show the effectiveness of our method.

Development of new shell structure in pf-shell nuclei

S. N. Liddick, P. F. Mantica, R. V. F. Janssens et al. · Journal of Physics Conference Series · 2006

β-delayed γ-ray measurements have been part of an experimental program at the NSCL to understand the role of the πf7/2 - νf5/2 proton-neutron monopole interaction in neutron-rich pf-shell nuclei above 48Ca. Central to this study has been an attempt to observe the development of new shell structure at N = 32, 34 through the systematic observation of E(2+1 ) as a function of neutron number. Additionally, the ground state spin and parity of odd-odd and odd-A nuclei were interpreted in an extreme single-particle model to follow the monopole migration of the νf5/2 as protons are removed from the πf7/2state.

Structure diagram of protective shell.

Liang Ge (541067), Zujing Zhang (18369129), Yinjun Wang (515331) et al. · Figshare · 2024

&lt;div&gt;&lt;p&gt;Injecting carbon dioxide is the most effective means of preventing and extinguishing fires in sealing hazardous areas, but the traditional method slowly and remotely injects carbon dioxide gas into the well after gasification on the ground, which is dependent on the complete mine pipe network without cooling effect. To inject liquid directly from the tank with vacuum interlayer and heat insulating powder for rapid inerting and cooling, a new approach using track mobile platform to go deep into the underground mine disaster area is proposed, so the liquid can be delivered to the nozzle at the end of DN40 large diameter pipe, and the continuous gasification jet can be realized. The experimental results show that: (1) The liquid volume in a tank of vacuum degree within 2.0 Pa and 200 mm interlayer reduced no more than 15.5% after 48 days; (2) Taking the pressure in the tank as the power source, because of environmental differences inside and outside the pipe after 100 m pressure holding delivery, the physical form of liquid and gas could be converted instantly; (3) The continuous discharge time without ice blocking for a tank full of 2 m&lt;sup&gt;3&lt;/sup&gt; liquid was about 10.5 min under 25 L dual mode nitrogen pressurization, which is 1/12 of injection time after ground gasification; (4) Based on the temperature decrease trend measured at different positions, the cooling characteristics on liquid gasification jet path are quantified, and the calculation formula of temperature changing with time on the center line of liquid gasification jet is obtained. Through this new approach, the integration of vacuum insulated storage, safe mobile transportation, and continuous and rapid release with large flow can be achieved for the liquid carbon dioxide.&lt;/p&gt;&lt;/div&gt;

The shell structure of atoms

Russell J. Boyd · Journal of Physics B Atomic and Molecular Physics · 1976

The radial density D(r) is computed from analytical Hartree-Fock wavefunctions for the first 54 elements of the periodic table. The calculations exhibit the familiar picture of spherical shells of electron density for the first three periods but for the fourth and fifth periods an ambiguity in the shell structure is observed. This ambiguity is analysed in terms of orbital contributions.
