This book explains the aspiring vision of a sustainable hydrogen generating system which employs nanotechnology one way or the other and presents a detailed update on research activities, achievements and challenges. It explores how nanotechnology is reshaping science in general and how this can be applied to the generation and storage of hydrogen energy. This book begins by highlighting the importance of hydrogen a source of sustainable energy and its impact on the technical advances of fuel cells, internal combustion engines, batteries and power plants. The book depicts the role of nanotechnology in the development of sustainable hydrogen. Comprehensive studies on various nanotechnologies involved in hydrogen generation are discussed in separate chapters, representing a complete picture of hydrogen generation utilizing nanotechnology. This book serves as a useful research tool for academics and practitioners looking towards new ways to develop and consume energy, without conceding our environment. Providing the advantages and disadvantages of each technology discussed, this book shows the benefits of utilizing nanotechnology in this field.

Scholarly Essay from the year 2010 in the subject Physics - Technical Physics, grade: -, - (Tripura Hochschule), language: English, abstract: The Langmuir-Blodgett (LB) technique is a way of making ultrathin nanostructured films with a controlled layer structure and crystal parameter, which have many envisioned applications in technology for optical and molecular electronic devices as well as in signal processing and transformation. LB films have a unique potential for controlling the structure of organized matter on the ultimate scale of miniaturization, and must surely find a niche where this potential is fulfilled. In this review paper the early development, technology and present status of LB film research and key papers are referred to.

This book is a modest attempt to provide a simple text for those who desire to equip with knowledge of herbal standardization, qualitative phytochemical investigation and antibacterial activity of herbal drugs. The authors have attempted to give as many illustrations as possible to make the concepts and principles clear to the reader. The large number of review materials is incorporated at each chapter after exhaustive survey of literature. We believe that this book will cater to the immediate needs of the students, researcher and the faculty members of the subject and will serve as an excellent book of its field. The book contains seven chapters which are systemically organized for the better understanding of the subject.

In these study samples of dried fruits, nuts, cereals and beans were analyzed for total AFs by high pressure liquid chromatography. Decontamination by different methods was also conducted. Biological and physical methods were evaluated to decontaminate the mycotoxin (aflatoxins) contaminated agricultural commodities, to prevent the threat to human health and the risk of great economic loss. In biological decontamination, some materials such as chemicals, herbal compounds/spices and plants were showed the inhibitory effect on the growth of Aspergillus flavus / Aspergillus parasiticus and total aflatoxins production. Thus some herbal compounds/spices and some chemicals as preservatives may successfully replace synthetic pesticides and provide an alternative method to protect our staple food from the toxic fungal contamination. In physical decontamination, application of oven heating and washing shows reduction in contamination level of AFB1 in different wheat varieties. Moreover, the cooking of rice in an excess of water showed maximum reduction on the levels of AFB1 and OTA in contaminated basmati rice samples than normal cooking and microwave oven cooking.

To evaluate nutritional significance of edible wild and unconventional fruits, 13 samples were collected from different areas of Pakistan. The fruits were analyzed for moisture, ash, vitamin C by Spectrophotometer, Sugars (Glucose, fructose & sucrose), macro minerals (Na, K, Ca and Mg) and micro nutrients (Co, Cr, Cu, Ni, Zn and Fe) by Atomic Absorption Spectrophotometer Due to lack of information available on energy, micro and macro nutrients composition of these fruits and their role in contemporary diet, the assessment was carried out on the basis of nutritional quality. All these fruits were found quite rich in nutrients. Furthermore, as these fruits have not yet been considered as an alternate food products, measures to be taken to conserve or utilize these fruits, in order to reduce wastage.
