Download or read book Sustainable Hydrogen Production Processes written by José Luz Silveira and published by Springer. This book was released on 2016-10-11 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work presents a comprehensive investigation of the most significant renewable hydrogen production processes. Technical, economic and ecological studies are described for the processes of steam reforming of ethanol, natural gas and biogas; water electrolysis with energy from renewable sources (wind power, photovoltaic and hydroelectric), and hydrogen production using algae. Aimed at mechanical and chemical engineering graduate students and researchers involved in environmental sciences, sustainable energy and bioenergy research, this book introduces readers to the latest developments in the field and provides essential reference material for future research. The book first presents a comprehensive literature review of the processes studied. Subsequently, it provides a technical report on assessing the energetic efficiency for each hydrogen production process, as well as an economic study of the respective hydrogen production costs. Lastly, the ecological efficiency of each process is addressed. Over the past few decades, the UNESP’s Group of Optimization of Energetic Systems, headed by Professor José Luz Silveira, has been pursuing research in the field of renewable energy generation. A major part of the group’s research focuses on the production of hydrogen as a fuel and its important contribution to mitigating the environmental impacts caused by pollutant emissions.

Download or read book Nanocosmetics and Nanomedicines written by Ruy Beck and published by Springer Science & Business Media. This book was released on 2011-04-06 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book "Nanocosmetics and nanomedicines: new approaches for skin care” contains a summary of the most important nanocarriers for skin delivery. Although “nanocosmetics” is a subject widely commented in the academy and the beauty industry, a book covering the skin care treatments using nanotechnological approaches with cosmetics and nanomedicines is still missing, therefore the need for this publication. This book is divided in three parts: The first one (Part A) is devoted to a brief review on the main topics related to the skin delivery and to the introduction of the subject “nanocosmetics”. The second part (Part B) presents different types of nanocarriers applied as skin delivery systems for cosmetics or drugs. The last part (Part C) shows a wide range of applications of nanotechnology on the skin care area as well as on dermatocosmetic and dermatological fields.

Available in PDF, EPUB and Kindle. Book excerpt: Ser neurona de la corteza cerebral, no es fácil. Son las células más evolucionadas en todas las especies generadas en el universo, en millones de años. Durante el desarrollo realizan una migración sin precedentes, cruzando las vastas selvas del sistema nervioso, construyendo sofisticadas redes neuronales, semejando edificios de seis niveles y generando tantas posibilidades de comunicación, como estrellas en el firmamento. Con su actividad en milivoltios de luces infinitas y liberando sustancias químicas como juegos pirotécnicos, estas neuronas son capaces de producir imaginación y pensamientos cada 20 milisegundos. Y con ello, conciben puentes, obras de arte, mundos nuevos, computadoras y hasta sueños. ¡Déjese llevar en esta nave! Viaje a través del pensamiento de los legendarios frenólogos de hace siglos, hasta llegar a descubrir, por usted mismo, cómo el cerebro hace juicios, toma decisiones, o genera una imagen mental.

This book was released on 2009-12-01 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fundamentos de Balanços de Energia é um manual que aborda duma forma simples e pedagógica a realização de balanços energéticos em sistemas em estado estacionário. O manual cobre uma parte significativa dos programas das disciplinas de Análise de Sistemas Químicos e Biológicos e Termodinâmica, dos atuais Mestrados Integrados em Engenharia Química e Engenharia do Ambiente. O texto inicia-se com um conjunto fundamental de conceitos e definições que suportam a aplicação do princípio da conservação da energia, ou seja a realização de balanços energéticos. Em seguida apresenta-se a equação geral dum balanço de energia e aplica-se a sistemas particulares, que não envolvem reação química. O cálculo das entalpias é abordado com detalhe em processos a temperatura variável (e pressão constante), nos processos de mudança de fase e de mistura. A última parte debruça-se sobre balanços de entalpia em sistemas onde ocorre reação química, sendo dado particular relevo à definição dos estados de referência na determinação dos vários termos da equação do balanço. Ao longo do texto, é feita referência aos vários problemas que se encontram resolvidos na última secção e que têm como objetivo sedimentar a informação apresentada.
