ABSTRACTUnderstanding the role of grain boundaries in controlling heat flow is critical to the success of many envisioned applications of nanocrystalline materials. This study focuses on the effect of grain boundaries on thermal transport behavior in nanocrystalline yttria-stabilized zirconia (YSZ) coatings prepared by metal-organic chemical vapor deposition.

Future Demands

This chapter describes the current situation of the chemical manufacturing industry and looks to the future demands on the sector such as: for sustainability, the advent of new bio-based feedstocks for improved energy management and the implications of these demands on the sector. These implications include definitions of sustainability criteria for the chemical manufacturing industry and the need for transparent reporting following the Triple Bottom Line approach. The important role of chemical (or more generally, process) engineers in delivering bio-based sustainable solutions is emphasised, but this also suggests that a new way of thinking about the discipline is required. Indeed, there are arguments that the demand for a sustainable chemical manufacturing sector could bring about the next paradigm shift in the discipline with concomitant education implications.

Moderating Role

Sustainability has been seen as a crucial issue that is being faced by many sectors in Malaysia which involves manufacturing sector. The Malaysian government has enhanced manufacturing organizations to apply green practices in the working environment to achieve corporate sustainability performance. In order for an organization to achieve corporate sustainability performance, the practices of the organization in using green technology such as sustainable transport is very important. The aim of this study is to examine the effects of sustainable transport on corporate sustainability performance with the moderating role of organization age. Drawing data from 130 Malaysia chemical manufacturing organizations, the model studies the moderating role of organization age on the sustainable transport and the corporate sustainable performance of the organizations. Partial Least Square (PLS) analysis is used in this study in order to analyze the data and the multistage sampling technique has also been used in this study. The results show that there is a positive relationship between sustainable transport and corporate sustainability performance. The results also suggest that organization age do not moderates the effect of sustainable transport and corporate sustainability performance. In achieving corporate sustainability performance, this study is important as it will guide employees in the manufacturing sector especially in chemical manufacturing organizations to practice the appropriate green practices such as sustainable transport.

Polymorphism refers to the ability of a solid to exist in more than one crystal structure. Apart from being of scientific interest, it is of practical importance in the pharmaceutical and chemical manufacturing industries. In pharmaceuticals the polymorphic form of the substance can affect the ease of manufacture or the rate of uptake by the human body [1]. There is consequently a great need to be able to understand, predict and control polymorphism. This work is part of a larger study using diffuse scattering methods to investigate the role of molecular flexibility and disorder in polymorphism. Diffuse scattering is sensitive to two-body correlations so can provide information about the intermolecular interactions that cannot be obtained from the Bragg peaks, such as how the displacement or orientation of a molecule is correlated with that of its neighbours. p-(N-methylbenzylidene)-p-methylaniline (MeMe) is a model system for studying polymorphic behaviour. The system is trimorphic with all three polymorphs exhibiting highly structured diffuse scattering patterns [2]. The short-range order has been modelled using the program ZMC in which the molecules are allowed to interact via Hooke's law springs and brought to thermal equilibrium using a Monte Carlo algorithm [3]. Here we present a comparison of the diffuse scattering in the different forms of MeMe and assess how successfully different models for the intermolecular interactions reproduce the observed diffuse scattering data.
