In recent years, there has been significant interest in the utilization of natural materials for nanomaterials which impact a broad range of fields including tissue engineering, smart textiles, electronics, energy, coatings and more. Natural polymers such as silk, have received renewed interest due to their unique properties and potential applications. Silk fibers are traditionally 10-20 µm in diameter. This book researches the scientific implications of reducing the diameter to the nanoscale and adding nanofillers in the form of carbon nanotubes by the electrospinning process. The effects of post processing treatments on the physico-chemical properties of the nanofibers were also studied. Statistical analysis was applied to develop processing windows that can reproduce nanofibers less than 100 nm in diameter. The extensive experimental works outlined in this book are creative and commercially justifiable solutions to technical challenges relating to the development, fabrication, characterization, and optimization of next-generation advanced nanomaterials.

The industrial sector is very promising for the use of solar thermal technology, since it accounts for a large share of the total final energy consumption (e.g. 27 % in Germany in 2010) and it predominantly uses the consumed energy as thermal energy (74 % in Germany in 2010). In order to develop this area of application, it is necessary to understand which industrial sectors have the highest potential, which processes within these sectors are most suitable for the integration of solar heat as well as to quantify the possible contribution to the industrial heat demand. For this thesis, the industrial heat consumption in Germany is analyzed, which leads to the selection of the 11 most promising sectors within industry. These are Chemicals, Food and beverages, Motor vehicles, Paper, Fabricated metal, Machinery and equipment, Rubber and plastic, Electrical equipment, Textiles, Printing and Wood. The theoretical potential of solar heat for industrial processes below 300 °C in Germany adds up to 134 TWh per year, the technical potential (considering efficiency measures, limited roof area and a solar fraction) being 16 TWh per year or 3.4 % of the overall industrial heat demand.Solar thermal systems can achieve higher system yields in industrial applications compared to domestic ones. At the same time, systems can be more complex in industrial applications. In order to design and operate solar process heat systems efficiently and to exploit the large potential, possible faults of such systems and their impact have to be evaluated. In this thesis, an implemented solar process heat system is methodically analyzed based on measurements and simulations with a validated model. Several faults are identified and their influence, as well as the influence of a reduced load on the system yield is evaluated. The analysis shows that a reduced load is most influential. Further, the most important impact factors on the system performance are identified: the collector parameters (?0, a1) and load characteristics (mass flow, temperature). The design of solar process heat systems is in many cases very demanding, hence costly. This high effort is a major barrier for a further development of solar heat for industrial applications. The decision to install solar thermal systems is in most cases based on solar heat generation cost. Collector field and heat store size are the most important figures for the estimation of the overall cost of a solar thermal system. Therefore, a simple approach for dimensioning the collector field and heat store is developed in this thesis in order to enable manufacturers and planners on one hand and costumers on the other hand to make a decision in favor or against a solar process heat system. In addition to investment cost, the specific system yield, which is determined for selected process heat applications in this thesis, is necessary to calculate solar heat generation cost. Finally, indications on the necessary accuracy of the load profile are provided to help to reduce effort in the design phase.

Designing is a task which requires a combination of technical knowledge, skill, training, patience and artistic imagination. Most of the designs made by man or available in nature have inherent symmetry in them. Considerable mathematical analysis is required to discover an order in such designs and encode them in mathematical descriptions. Moreover, such analysis is usually specific to a particular design (or a class of designs) and is difficult to generalize. Geometric modelling can be used as a design tool to avoid unnecessarily tedious or repetitive tasks. This allows the artist to work on the design idea rather than its implementation. The work presents a unified modelling scheme for artists, craftsmen and common users to facilitate user-defined and automatic generation of designs starting with the simple geometric primitives at the lowest level and creation, storage and retrieval of statically and dynamically symmetric patterns that can be used to generate design layouts. It has direct applications in the domain of art, metal engraving, designer furniture, textiles, jewelry, woodcarvings, wallpapers, tiles, flower vases, etc.

Medical Textile is one of the most rapidly expanding sectors in the technical textile market. Medical Textiles are the products and constructions used for medical and biological applications and are used primarily for first aid, clinical and hygienic purposes. It consists of all those textile materials used in health and hygienic applications in both consumer and medical markets. Skin disease is due to allergy, variation in climate, wrong usage of chemicals, tablets, injection, this will create problem to human body. Most of the skin allergies are caused due to over secretion of histamine by mast cell. Normally mast cells are made by bone marrow. They are part of immune system. These cells are more in skin, lungs and intestine. Due to variation in atmospheric condition, histamine is secreted by mast cell that will cause blister in skin, lungs and intestine. In order to suppress this histamine, antihistamine medicines were used. In this book, a discussion was made on the application of the fabric treated with two different herbals which have antihistamine property to release antihistamine to prevent some skin diseases.

Modification of Fibres for Technical Applications
128,00 CHF *
ggf. zzgl. Versand

The book deals with the physical and chemical modification of natural and synthetic fibres for technical applications. Natural fibres and synthetic fibres/ filaments are often inadequate to be used in technical textiles. The high level of moisture absorption of natural fibres, poor wettability by non-polar plastics, and insufficient adhesion between untreated fibres and the polymer matrix, result in poor properties in composites. Synthetic fibres often lack the required mechanical and thermal properties to be used for technical applications. The book will thus encompass methods to physically and chemically modify fibres for technical applications.
