This book introduces the reader to the state of the art in nanostructured anode and cathode electrocatalysts for low-temperature acid and alkaline fuel cells. It explores the electrocatalysis of anode (oxidation of organic molecules) and cathode (oxygen reduction) reactions. It also offers insights into metal-carbon interactions, correlating them with the catalytic activity of the electrochemical reactions. The book explores the electrocatalytic behaviour of materials based on noble metals and their alloys, as well as metal-metal oxides and metal-free nanostructures. It also discusses the surface and structural modification of carbon supports to enhance the catalytic activity of electrocatalysts for fuel-cell reactions.

Set in Southern California's San Gabriel Valley, Diana Marie Delgado's debut poetry collection follows the coming-of-age of a young Mexican-American woman trying to make sense of who she is amidst a family and community weighted by violence and addiction. With bracing vulnerability, the collection chronicles the effects of her father's drug use and her brother's incarceration, asking the reader to consider reclamation and the power of the self.

This book presents the first overview of the Toarcian Oceanic Anoxic Event in the southern Iberian paleomargin, in the western Tethys. The study of catastrophic events that affected the ecosystems in the past is of great interest, because it offers the possibility of establishing models that can be applied to current and future environmental changes. The book provides comprehensive information on the changes in marine ecosystems in connection with a global massive extinction, the Early Toarcian, and with the deposition of black shales, global warming and a disruption of the carbon cycle. In addition, the book describes the incidence of this event in this part of the Tethys close to the connection with the Protoatlantic, the Hispanic Corridor. Special attention is paid to sedimentological and ichnological aspects, fossil content (macroscopic and microscopic), and geochemistry. It also presents the facies changes related to fragmentation of the shelf and the evolution to hemipel agic troughs and swells in this paleomargin. Lastly, it characterizes this anoxic event in under-researched outcrops from southern Spain and compares the findings with those in well-known sections from northern and central Europe. This book offers a unique resource for all researchers interested in the Toarcian Oceanic Anoxic Event, but also in oceanic anoxic events that occurred during the Mesozoic in general, because of their similarity to recent climatic changes.

This book is directed mainly at teachers of engineering thermodynamics, but it can also be very useful for the student who wants to read a comprehensive work on the subject alone. The structure of the information contained in the book has been made explicit to the reader, so that he or she can choose what to read and what to leave out with a safe criterion. At the beginning of each chapter, the reader can find one or two types of help. A chapter index can help when forming a global vision of the chapter. We have also considered it useful to insert some comments in the text, generally on conceptual issues that students usually don't think about at all, but that may be of interest for the teacher, as well as some hints about what kind of things students usually find hard to understand based on our own classroom experiences.

Existing nanocomposite materials used for satellite applications don't offer the required conductivity and electromagnetic shielding protection, requiring metal shields in order to survive in space. The AFRL Materials and Manufacturing Directorate in conjunction with the private sector have developed a material that promises to blend the attributes of nanocomposites and metal materials. The M55J/RS3 material consists of carbon fibers combined with a polyisocyanate matrix, in which nickel nanostrandsTM are added. The research effort investigated the changes in the EMI and ESD of the material after being subjected to cyclic loads. Four configurations of a symmetric layup with fibers oriented at 0/90/45/-45 degrees were evaluated.

The literary archive of the U.S.-Mexican War (1846-1848) opens to view the conflicts and relationships across one of the most contested borders in the Americas. Most studies of this literature focus on the war's nineteenth-century moment of national expansion. In The Literatures of the U.S.-Mexican War, Jaime Javier Rodriguez brings the discussion forward to our own moment by charting a new path into the legacies of a military conflict embedded in the cultural cores of both nations. Rodriguez's groundbreaking study moves beyond the terms of Manifest Destiny to ask a fundamental question: How do the war's literary expressions shape contemporary tensions and exchanges among Anglo Americans, Mexicans, and Mexican Americans. By probing the war's traumas, anxieties, and consequences with a fresh attention to narrative, Rodriguez shows us the relevance of the U.S.-Mexican War to our own era of demographic and cultural change. Reading across dime novels, frontline battle accounts, Mexican American writings and a wide range of other popular discourse about the war, Rodriguez reveals how historical awareness itself lies at the center of contemporary cultural fears of a Mexican "invasion," and how the displacements caused by the war set key terms for the ways Mexican Americans in subsequent generations would come to understand their own identities. Further, this is also the first major comparative study that analyzes key Mexican war texts and their impact on Mexico's national identity.
