Materials selection for microsystems actuators
The recent developments of novel thin film materials and their associated processes have marked the onset of change in the design philosophy of Micro-Electro- Mechanical Systems (MEMS) from process centric to performance centric. This presents an opportunity to improve the performance of MEMS …

Learning-Derived Cost Evolution in Materials Selection
Materials selection is a complex, but important, problem for manufacturing firms. Poor material choices can negatively affect the firm's market share or profits. In the face of this complexity, most selection methods make a number of simplifications, including limiting problem scope to selection …

A cluster analysis method for materials selection
Materials have typically been selected based on the familiarities and past experiences of a limited number of designers with a limited number of materials. Problems arise when the designer is unfamiliar with new or improved materials, or production processes more efficient and economical than past …

Materials selection and processing for reliable neural interfaces
The understanding of the brain would be revolutionized by a tool that can measure intra- and extra-cellular electrical potentials on a parallelized scale, without disrupting the neural physiology. Existing technologies do not sufficiently carry out these functions. Using a thermal drawing process …

Light-weight materials selection for high-speed naval craft
… analysis study was conducted on the process of materials selection for high-speed naval craft using the Modified Digital Logic (MDL) method proposed by B. Dehgham-Manshadi et al in ref [17]. The purpose is to show how this method along with Ashby's material selection process can be integrated to …

The role of demand uncertainty in materials selection : a case study on aluminum recycling
… shortfall is the use of secondary, or recycled, materials which provides both economic and environmental benefits. The increased use of secondary materials is limited by numerous factors; one such factor of concern is uncertainty. One form of uncertainty that all producers face is consumer …

An alloy selection and processing framework for nanocrystalline materials
Nanocrystalline materials have a unique set of properties due to their nanometer-scale grain size. To harness these properties, grain growth in these materials needs to be suppressed, particularly in order to process bulk nanocrystalline components and to use them reliably. Alloying the material …

Structure-property relationships and salt selection for functional organic materials
… to the apparent tendency for 4-nitrophenol materials to crystallise in non-centrosymmetric space groups. This included a study of packing analysis and graph set notations. Two separate isostructural groups of cocrystal of salt structures were found to share packing similarities. Potential …

Exploring Quantum Phenomena in 2D Materials: From Valley Topology and Exciton Selection Rules to Tuning Magnetic Correlations
… presents two independent parts under the common theme of quantum phenomena in 2D materials: Part I introduces a gauge-invariant, quantized interband index for multiband 2D systems and uses it in two applications: A) to analyze valley topology, and B) to derive gauge-invariant exciton selection …

Homespun Fun: Theme Parks, Suburbia, and the Postwar Child
Scholars of theme parks and their histories recognize that a carefully crafted family-friendly environment is the cornerstone of the themed amusement landscape dating back to the 1950s. From marketing and promotional material; to in-park signage and ride narratives; to the themes of childlike …

Natural selection successfully taught
"Natural selection, one of biology's most important concepts, has proven vexing to both teach and learn. Polanyi's concept of tacit knowledge and Broudy's concept of ""knowing with"" served as the basis for developing materials to teach natural selection. These materials sought to make explicit to …

New screening methodology for selection of polymeric materials for transdermal drug delivery devices
… upsetting national budgets. Therefore, the selection of a precise and affordable drug delivery technology is seen as the most practical solution for governments, health care professionals, and consumers. Transdermal drug delivery patches (TDDP) are one of the best economical technologies …
