Magnesium is the lightest metallic construction material and bears high potential for automotive components, medical implants and energy storage systems. However, the practical use of untreated magnesium alloys is restricted as they are prone to corrosion. An essential prerequisite for the inhibition or control of the degradation process is a deeper understanding of the underlying corrosion mechanisms. For instance, identifying the reaction pathways most relevant for the release of gaseous hydrogen — one of the main products during magnesium corrosion — builds the foundation for adapting the hydrogen evolution rate in general. A possible approach to modulate the hydrogen evolution and magnesium dissolution rate is the introduction of small organic molecules that either stabilize the corroding surface or capture corrosive species. Such molecules constitute benign and useful materials to modify the service environment of magnesium for applications that require tailored degradation properties. This thesis illuminates different aspects of magnesium degradation, ranging from atomistic insights into the corrosion process itself to further developing strategies for effective corrosion control. By combining atomistic simulations and machine learning techniques, a holistic framework is developed to improve understanding and enable more efficient magnesium corrosion engineering in the future.

We live in an age of extreme corporate concentration, in which global industries are controlled by just a few giant firms-big banks, big pharma, and big tech, just to name a few. But concern over what Louis Brandeis called the "curse of bigness" can no longer remain the province of specialist lawyers and economists, for it has spilled over into policy and politics, even threatening democracy itself. History suggests that tolerance of inequality and failing to control excessive corporate power may prompt the rise of populism, nationalism, extremist politicians, and fascist regimes. In short, as Wu warns, we are in grave danger of repeating the signature errors of the twentieth century. In The Curse of Bigness, Tim Wu, special assistant to President Biden for technology and competition policy, explains how figures like Brandeis and Theodore Roosevelt first confronted the democratic threats posed by the great trusts of the Gilded Age-but the lessons of the Progressive Era were forgotten in the last 40 years. He calls for recovering the lost tenets of the trustbusting age as part of a broader revival of American progressive ideas as we confront the fallout of persistent and extreme economic inequality

A revelatory look at the rise of the 'attention merchants', the marketeers who harvest, influence and control our consumption in ways previously unimagined, for resale to advertisers. Tim Wu argues that this is not simply the by- product of recent inventions but the end result of more than a century's growth and expansion in the industries that feed on human attention.

A New Yorker and Fortune Best Book of the Year "A must-read for all Americans who want to remain the ones deciding what they can read, watch, and listen to.” —Arianna Huffington Analyzing the strategic maneuvers of today’s great information powers—Apple, Google, and an eerily resurgent AT&T—Tim Wu uncovers a time-honored pattern in which invention begets industry and industry begets empire. It is easy to forget that every development in the history of the American information industry—from the telephone to radio to film—once existed in an open and chaotic marketplace inhabited by entrepreneurs and utopians, just as the Internet does today. Each of these, however, grew to be dominated by a monopolist or cartel. In this pathbreaking book, Tim Wu asks: will the Internet follow the same fate? Could the Web—the entire flow of American information—come to be ruled by a corporate leviathan in possession of "the master switch"? Here, Tim Wu shows how a battle royale for the Internet’s future is brewing, and this is one war we dare not tune out.

Iluze o světě bez hranic. V 90. letech 20. století akademici i ředitelé velkých firem považovali Internet za hnací motor nové globalizace, která podkope autoritu a význam klasického státu. Zdálo se, že příchod Internetu je předzvěstí nového způsobu uspořádání lidských záležitostí, který nás navždy vysvobodí z tyranie teritoriálních vládců. Tato kniha vypráví příběh o Internetu, který v 90. letech 20. století začal narušovat moc jednotlivých státních správ, a následném boji vlád o ovládnutí nového média. Je to příběh smrti snu o kyberkomunitách, které si vládnou samy, a jednou provždy tak uniknou zeměpisným omezením. Je to také příběh o zrození a prvních letech nového druhu Internetu - územně ohraničené sítě, kde regionální zákony, státní moc a mezinárodní vztahy mají stejný význam jako technická invence. Pohled autorů na vývoj Internetu ale není pesimistický. Ukazuje, že zeměpisně ohraničený Internet má řadu nedoceňovaných výhod, zohledňuje potřeby jednotlivých uživatelů i firem, které na Internetu podnikají.

In this provocative new book, the authors tell the fascinating story of the Internet's challenge to governmental rule in the 1990s, and of the fate of one idea--that the Internet might liberate users forever from government, borders, and even their physical selves.
