Hardback. Condition: New. Classical alchemy divided matter into just four elements, although some argued for the recognition of a fifth element. Modern chemistry divides matter into a whole array of elements, commonly known as the periodic table. In this table boron is the fifth element, and it sits right at the intersection of many classes of elements; between the metals and the non-metals; between those with just the right number of electrons for bond formation, and those with far too few; between those that form bonds by sharing electrons, and those that give them away. This dichotomy is apparent throughout the chemistry of boron and produces a wonderful variety of effects. From too little boron harming plants, to too much being toxic, boron inhabits a nuanced position throughout science and history. Examples include its inspired use in glass that led to strategic shortages in World War I, whereas too much of it had the potential to stop nuclear reactors in World War II; boron even featured in the Cold War with a brief boom-and-bust in the development of new high-energy fuels. From superconductors to cancer treatments, boron is anything but boring.Beginning with some basics of chemistry, readers are led on an exciting journey exploring the history of this intriguing element into its modern uses that are all around us.…

Taschenbuch. Condition: Neu. Neuware - As the fields of organometallic and coordination chemistry of the transition metals has grown more mature, the under-explored chemistry of the rare-earths and actinides has drawn the attention of research groups from across the globe looking for new fundamental discoveries and access to compounds with unique properties. The rare-earths-the group 3 metals and the 4f lanthanide series-have long shown many interesting properties in the solid state which exploit their unique electronic configurations. However, it is the molecular chemistry of these metals that has expanded dramatically in recent years as researchers identify the differences between-and unique features of-their molecular compounds. Recent highlights include the identification of new oxidation states and patterns of reactivity as well as applications in medical imaging and health care which represent new and exciting areas of research. The actinides show a wide range of different properties as a consequence of their radioactivity and radiochemistry, but this has not stopped recent rapid progress into the exploration of their unique chemistry. Uranium, in particular, shows huge potential with its transition metal-like range of oxidation states (+2 to +6), and in specialised laboratories, the heavier actinides are also beginning to show their unique chemistry. This Special Issue aims to bring together these strands of research in an openly-accessible way to allow better communication of these advances to a wider audience. This is necessary as, despite these exciting advances, the rare-earths and actinides are still much neglected topics in both school and undergraduate curriculums. Contributions in the above-mentioned areas will allow new research in the rare-earths and actinides to inform and influence the next generation of scientists and keep the field as vibrant as it is today.…
