The Relationship

Organic active nanophotonics: excited-state coupled photonic behaviours strongly determine the optical performances of organic nanomaterials. The photonic actions and related material properties can be well controlled by tailoring the intra/inter-molecular excited-state processes.

Comprehensive Study

successful design of folding bicycle should take into account the function, material properties, and fabrication process. There are some other factors that should be considered in anticipating the behavior of materials for folding bicycle. In order to understand the relationship between material properties and design of a folding bicycle and also for the future direction in new materials with new design, a comprehensive study on the design under different conditions are essential. Therefore, a systematic study on the relationship between material properties and design for folding bicycle has been performed. The advantages and disadvantages matrix between conventional bicycle and folding bicycle is presented for better understanding of the materials properties and design. It was found that the materials properties of the folding bicycle frame such as fatigue and tensile strength are the important properties for the better performance of the frame. The relationship between materials properties and design is not straight forward because the behavior of the material in the finished product could be different from that of the raw material. The swing hinge technique could be a better technique in the design for the folding bicycle frame.

The Relationship

A relative method, defined as indirect approach to evaluate the material properties via the relationship between unknown properties and a known property, is proposed to estimate some properties that could not be measured by the traditional methods for ceramics. Experiments and theoretic analysis based on the relative method were carried out in this study to estimate the properties in following aspects: determining the temperature dependence of elastic modulus of some machineable ceramics by comparing the deflections; obtaining the modulus and strength of ceramic coatings supported by substrates, from the variation in properties of the rectangular beam samples before and after coating; estimating the residual stresses in tempered glass by comparing the change in the surface strength after strengthening.

AbstractThe small punch test (SPT) was developed for situations where source material is scarce, costly or otherwise difficult to acquire, and has been used for assessing components with variable, location-dependent material properties. Although lacking standardization, the SPT has been employed to assess material properties and verified using traditional testing. Several methods exist for equating SPT results with traditional stress–strain data. There are, however, areas of weakness, such as fracture and fatigue approaches. This document outlines the history and methodologies of SPT, reviewing the body of contemporary literature and presenting relevant findings and formulations for correlating SPT results with conventional tests. Analysis of literature is extended to evaluating the suitability of the SPT for use with additively manufactured (AM) materials. The suitability of this approach is shown through a parametric study using an approximation of the SPT via FEA, varying material properties as would be seen with varying AM process parameters. Equations describing the relationship between SPT results and conventional testing data are presented. Correlation constants dictating these relationships are determined using an accumulation of data from the literature reviewed here, along with novel experimental data. This includes AM materials to assess the fit of these and provide context for a wider view of the methodology and its interest to materials science and additive manufacturing. A case is made for the continued development of the small punch test, identifying strengths and knowledge gaps, showing need for standardization of this simple yet highly versatile method for expediting studies of material properties and optimization.

Media Formats

Musical identities are forged in relation to the material properties of media formats. The cultures of listening and modes of identification fostered by the 78-rpm disc, for example, are not the same as those that took shape around the LP or the MP3. Each technology affords different modes of musical identification, fandom, enjoyment, and taste. To read Desert Island Discs as a continuous archive of self-presentation or a straightforward reflection of musical taste is thus to overlook a key point: the programme equally reflects seven decades of change in the material cultures of music. This chapter combs the online Desert Island Discs archive for evidence of the relationship between the discographic self and the ‘discomorphosis’ of music, focusing on such conjunctures as the hypothetical wind-up gramophone that furnished the island in 1942, the introduction of the LP and transistor radios around 1950, and the introduction of the iPod in 2001.

AbstractIn this paper we examine the relationship between precursor structure and material properties for films produced from several leading organosilicon precursors on a common processing platform. Results from our study indicate that for the precursors tested the nature of the precursor has little effect upon film composition but significant impact on film structure and properties.

The Relationship

Meniscal horns attach the meniscus to the underlying subchondral bone. Successful meniscal replacements must maintain horn attachments of the menisci, hence recent studies have been aimed at characterizing the material properties of the ligamentous horn attachments. In order to mimic material properties in tissue engineered meniscal replacements, we must understand how these properties are influenced by mineral and matrix constituents. Additionally, understanding how osteoarthritis alters the meniscal horn attachments may elucidate appropriate design considerations of such tissue engineered replacements. Therefore, this study investigated the relationship between mechanical and mineral properties of osteoarthritic meniscal attachments.
