Materials Technology for Engineers pre-test 1 notesmusadoto
Materials are probably more deep-seated in our culture than most of us realize. Transportation, housing, clothing, communication, recreation, and food production virtually every segment of our everyday lives is influenced to one degree or another by materials. Historically, the development and advancement of societies have been intimately tied to the members’ ability to produce and manipulate materials to fill their needs. In fact, early civilizations have been designated by the level of their materials development (i.e., Stone Age, Bronze Age). The earliest humans had access to only a very limited number of materials, those that occur naturally: stone, wood, clay, skins, and so on. With time they
discovered techniques for producing materials that had properties superior to those of the natural ones; these new materials included pottery and various metals. Furthermore, it was discovered that the properties of a material could be altered by heat treatments and by the addition of other substances. At this point, materials utilization was totally a selection process, that is, deciding from a given, rather limited set of materials the one that was best suited for an application by virtue of its characteristics. It was not until relatively recent times that scientists came to understand the relationships between the structural elements of materials and their properties. This knowledge acquired in the past 60 years or so, has empowered them to fashion, to a large degree, the characteristics of materials. Thus, tens of
thousands of different materials have evolved with rather specialized characteristics that meet the needs of our modern and complex society; these include metals, plastics, glasses, and fibers. The development of many technologies that make our existence so comfortable
has been intimately associated with the accessibility of suitable materials. An advancement
in the understanding of a material type is often the forerunner to the stepwise progression of a technology. For example, automobiles would not have been possible without the availability of inexpensive steel or some other comparable substitute. In our contemporary era, sophisticated electronic devices rely on components that are made from what are called semiconducting materials.

Optimisation of Biogas Production using NanotechnologyYogeshIJTSRD
Nanotechnology largely affects a more extensive scope of biotechnological, pharmacological and unadulterated innovative applications. In this paper we would be covering the use of nanotechnology in the production as well as optimisation of biogas. This paper clearly shows the potential and relationship between the both – biogas production and nanotechnology via various feedstock characterisation studies which was done during this paper. The aim of this paper is to showcase how these both technologies complement each other and how nanotechnology is applied in feedstock and convert it to biogas. Our study shows how nanotechnology is applied on pressmud and gas production is enhanced at laboratory level. The digestion of pressmud with nanomaterials were studied. Our study clearly indicates that the biogas production can surely be enhanced in case of treating pressmud by using magnetite nanoparticles which gives higher methane yields compared to normal digestion without nanoparticles. This study not only confirms the enhanced biogas generation from pressmud but also confirms that on other biodegradable material the same principle can be applied and gas production can be enhanced. Our study surely will be an important tool for implementing of nanotechnology in biogas research and enhanced production wherever the press mud is available.
