exchange membranes (AAEMs) are cutting-edge polyelectrolyte materials with growing renewable energy applications including fuel cells, batteries, hydrogen electrolyzers and electrodialysis technologies. Their use in relatively new alkaline exchange membrane fuel cells (AEMFCs) is designed to produce cost-effective clean energy (electricity) produced by a chemical reaction. Rigorous studies are being conducted to meet the requirements of AAEMs precisely tailored for high anion conductivity and durability for future high energy efficient devices. Hence, over the past few years the academic and industrial scientific communities have explored various polymeric, composite and inorganic materials and studied their properties as a potential AAEM. The accumulated literature in this area of investigation is vast and in order to provide the community with the tools needed to strive forward, there is a clear need to condense this information in a single volume. Alkaline Anion Exchange Membranes for Fuel Cells meets this need with a comprehensive overview of the properties of these membranes and their applications. The book considers recent developments, common challenges, and the long-term prospects for this field of research and engineering. It constitutes a one-stop resource for the development and production of AAEM fuel cells and related electrochemical applications. Alkaline Anion Exchange Membranes for Fuel Cells readers will find: Discussion of electrochemical applications like redox flow batteries, water electrolysis, and many moreDetailed treatment of specially tailored cationic groups such as quaternary ammonium and guanidiniumExpert advice on efficient fabrication and electrode assembly Alkaline Anion Exchange Membranes for Fuel Cells is ideal for electrochemists, materials scientists, polymer chemists, electrical engineers, and anyone working in power technology or related fields.Nanocellulose: A Biopolymer for Biomedical Applications

Par Ian Miller. 2024
At the end of the last century, the idea of self-esteem became enormously influential. A staggering amount of psychological research…
and self-help literature was published, and before long was devoured by readers. Self-esteem initiatives permeated American schools. Self-esteem became the way of understanding ourselves, our personalities, our interactions with others. Nowadays, few people think much about the idea of self-esteem—but perhaps we should.Self-Esteem: An American History is the first historical study exploring the emotional politics of self-esteem in modern America. Written with verve and insight, Ian Miller’s expert analysis explores the critiques of self-help which accuse it of propping up conservative agendas by encouraging us to look solely inside ourselves to resolve life’s problems. At the same time, he reveals how African American, LGBTQ+ and feminist activists endeavored to build positive collective identities based upon self-esteem, pride and self-respect.This revelatory book will be essential reading for anyone with an interest in the history of mental health, well-being, emotions in the United States’ unique society and culture.Homo Numericus: The coming 'civilization'
Par Daniel Cohen. 2024
From Amazon to Tinder, from Google to Deliveroo, there is no facet of human life which the digital revolution has…
not streamlined and dematerialised. Its objective was to reduce the cost of physical interactions by forgoing face-to-face interactions, a direct result of the free-market shock of the 1980s, which sought to seamlessly expand the marketplace in every possible dimension. Today, we can be algorithmically entertained, educated, cared for and courted in a way which was impossible in the old industrial society, where institutions structured the social world. Today, these institutions have been replaced by monetised virtual contact. As with the industrial revolution of the past, the digital revolution is creating a new economy and a new sensibility, bringing about a radical revaluation of society and its representations. While obsessed with the search for an efficient management of human relations, the new digital capitalism gives rise to an irrational and impulsive Homo numericus prone to an array of addictive behaviours. Far from producing a new agora, social media produce a radicalization of public debate in which hate-filled speech directed against adversaries becomes the norm. The good news is that these outcomes are not inevitable. Technologies have not taken control of our lives. The digital revolution also offers an alternative path: one that leads to a world in which every word deserves to be listened to, without a transcendent truth hanging over it. Are we able to seize the new opportunities opened up by the digital revolution without succumbing to its dark side?Familiar Violence: A History of Child Abuse
Par Heather Montgomery. 2024
Child abuse casts a long shadow over the history of childhood. Across the centuries there are numerous accounts of children…
being beaten, neglected, sexually assaulted, or even killed by those closest to them. This book explores this darker side of childhood history, looking at what constituted cruelty towards children in the past and at the social responses towards it. Focusing primarily on England, it is a history of violence against children in their own homes, covering a large timeframe which extends from medieval times to the present. Undeniably, the experience of children in the past was often brutal, and children were treated with, what seems to contemporary mores, callousness, and cruelty. However, historians have paid far less attention to how the mistreatment of children was understood within its contemporary context. Most parents, both now and in the past, loved their children and there have always been widely shared understandings of the boundaries that separate the acceptable treatment of children from the intolerable and morally wrong. This book will examine how these boundaries have changed and been contested over time and, in doing so, provides a context to the many forms of violence experienced by children in the past.The Secrets of the Titanic

Par Gerardo Aldana. 2021
To the modern eye, the architects at Chich’en Itza produced some of the most mysterious structures in ancient Mesoamerica. The…
purpose and cultural influences behind this architecture seem left to conjecture. The people who created and lived around this stunning site may seem even more mercurial. Near the structure known today as the Great Ball Court and within the interior of the Lower Temple of the Jaguar, a mural depicts a female Mayan astronomer called K'uk'ul Ek' Tuyilaj. Weaving together archaeology, mathematics, history, and astronomy, Calculating Brilliance brings to light the discovery by this Mayan astronomer, which is recorded in the Venus Table of the Dresden Codex. As the book demonstrates, this brilliant discovery reverberated throughout Mayan science. But it has remained obscured to modern eyes. Jumping from the vital contributions of K'uk'ul Ek' Tuyilaj, Gerardo Aldana y Villalobos critically reframes science in the pre-Columbian world. He reexamines the historiography of the Dresden Codex and contextualizes the Venus Table relative to other Indigenous literature. From a perspective anchored to Indigenous cosmologies and religions, Aldana y Villalobos delves into how we may understand Indigenous science and discovery—both its parallels and divergences from modern globalized perspectives of science. Calculating Brilliance brings different intellectual threads together across time and space, from the Classic to the Postclassic, the colonial period to the twenty-first century to offer a new vision for understanding Mayan astronomy.Buried Biscuits (Jack Russell: Dog Detective)

Par Lane Walker. 2020
Rock Conrad was set to begin the best and final year of his high school education. He could hardly wait.…
This was his year! Rock and Eddie, best friends and teammates, were poised to make history as the first ever bass fishing state champions at Polk High School. Last year they finished in the top ten, but this year their eyes were on first place. During the summer, the pair spent many hours on Rock’s boat, perfecting their fishing skills. The many lakes throughout Texas kept Rock occupied and happy. When he was on the water, he was at home. This was also set to be an epic year on the gridiron for the Polk High Panthers. The state of Texas is known for many things, and football is definitely one of them. The football players were local celebrities. Desmond Ward, the senior quarterback, was a fan favorite and had already accepted a full ride scholarship at Texas A&M. His high school passing records ranked him at the top with some of the greatest players to come out of Texas. Rock wasn’t interested in Desmond, his scholarship, or his records. In fact, he despised him. He didn’t despise the game of football. Rock actually studied it and loved it. He just wasn’t good at playing it. He was good at bass fishing, though, and he knew his time to shine was this year. His hopes and dreams quickly unraveled when a freak accident changed everything. Polk High’s fishing dream team was no more. Rock was put in an impossible spot. He was either going to come out the hero or the laughing stock of the school. This was not how he envisioned his senior year.Barry Sanders: Star Running Back (Sports Reports)

Aven Green Sleuthing Machine (Aven Green Series)
Par Dusti Bowling, Gina Perry. 2021
Third-grader Aven Green has been solving mysteries for a really long time—a whole month! She’s solved many important cases like…
The Mystery of the Cranky Mom, The Mystery of the Missing Ice Cream, and The Mystery of the Smelly Feet. Her record is nearly 100% (only The Mystery of the Cereal in My Underpants remains unsolved to this day). Aven asks all the right questions, wields her detective kit carefully, and follows up on every clue. Then her teacher’s lunch bag (with her lunch still in it) is taken and Aven’s great-grandma’s beloved dog goes missing! Can this perceptive detective crack two cases at the same time? Luckily, Aven has a super-powered brain full of lots of extra brain cells to take on both cases. See, she was born without arms, so all of the cells that were supposed to make her arms went into making her brain instead. At least that’s her working theory for The Mystery of Why I Have So Many Extra Brain Cells.
