Less than a decade ago, lead halide perovskite semiconductors caused a sensation: Solar cells exhibiting astonishingly high levels of efficiency. Recently, it became possible to synthesize nanocrystals of this material as well. Interestingly; simply by controlling the size and shape of these crystals, new aspects of this material literally came to light. These nanocrystals have proven to be interesting candidates for light emission. In this thesis, the recombination, dephasing and diffusion of excitons in perovskite nanocrystals is investigated using time-resolved spectroscopy. All these dynamic processes have a direct impact on the light-emitting device performance from a technology point of view. However, most importantly, the insights gained from the measurements allowed the author to modify the nanocrystals such that they emitted with an unprecedented quantum yield in the blue spectral range, resulting in the successful implementation of this material as the active layer in an LED. This represents a technological breakthrough, because efficient perovskite light emitters in this wavelength range did not exist before.

A fascinating collection of the pictures, figures, and diagrams that chemists create to explain their craft

In A Chemical History Tour, Arthur Greenberg took readers on a wild romp through the history of chemistry, introducing the unique characters, sometimes bizarre theories, and novel experiments that ultimately produced the modern science. Now Greenberg returns with more tales of chemistry glory, lovingly chronicling the extraordinary artwork that alchemists and chemists have produced in their pursuit of understanding the nature of matter in The Art of Chemistry: Myths, Medicines, and Materials.

The Art of Chemistry employs 187 figures (including 16 full-color plates) to illuminate 72 essays on the mythical origins, wondrous experiments, and adventurous explorers in the annals of chemistry. Greenberg divides his delightful study into eight sections:

• Spiritual and Mythological Roots
• Stills, Cupels, and Weapons
• Medicines, Purges, and Ointments
• An Emerging Science
• Two Revolutions in France
• A Young Country and a Young Theory
• Specialization and Systemization
• Some Fun

Each section tracks chemistry’s incremental progress from myth to modern science, featuring the figures and diagrams that early chemists used to explain their craft. Along the way, readers will meet the deadly basilisk and the fabulous phoenix that populated the lore of pre-modern chemistry, learn the contributions to chemistry of the American natural philosopher Benjamin Franklin, and encounter Antoine Lavoisier, the father of modern chemistry and perhaps France’s greatest economist.

Greenberg also examines our fundamental connections with science through two personal essays, one on an adolescent friend who improbably (but perhaps inevitably) became a world-renowned entomology professor and the other on his quest to discover his own chemical heritage. The Art of Chemistry is sure to inform and entertain anyone interested in our eternal quest to know the natural world.

What do bird flocks, bacterial swarms, cell tissues, and cytoskeletal fluids have in common? They are all examples of active matter. This book explores how scientists in various disciplines, from physics to biology, have collated a solid corpus of experimental designs and theories during the last two decades to decipher active systems. The book addresses, from a multidisciplinary viewpoint, the field of active matter at a colloidal scale. Concepts, experiments, and theoretical models are put side by side to fully illuminate the subtilities of active systems. A large variety of subjects, from microswimmers or driven colloids to self-organized active fluids, are analysed within a unified perspective. Generic collective effects of self-propelled or driven colloids, such as motility-induced flocking, and new paradigms, such as the celebrated concept of active nematics in reconstituted protein-based fluids, are discussed using well-known experimental scenarios and recognized theories. Topics are covered with rigor and in a self-consistent way, reaching both practitioners and newcomers to the field. The diversity of topics and conceptual challenges in active matter have long hampered the chance to explore the field with a general perspective. This monograph, the first single-authored title on active matter, is intended to fill this gap by bridging disparate experimental and theoretical interests from colloidal soft matter to cell biophysics.

Prefaces are like speeches before the c- tain; they make even the most self-forgetful performers seem self-conscious. - William Allen Neilson The study of phenomena and processes at the phase boundaries of m- ter is the realm of the surface scientist. The tools of his trade are drawn from across the spectrum of the various scienti?c disciplines. It is therefore interesting that, in investigating the properties of such boundaries, the s- facist must transcend the interdisciplinary boundaries between the subjects themselves. In this respect, he harkens back to the days of renaissance man, when knowledge knew no boundaries, and was pursued simply for its own sake, in the spirit of enlightenment. Chemisorption is a gas-solid interface problem, involving the inter- tion of a gas atom with a solid surface via a charge-transfer process, during which a chemical bond is formed. Because of its importance in such areas as catalysis and electronic-device fabrication, the subject of chemisorption is of interest to a wide range of surfacists in physics, chemistry, materials science, as well as chemical and electronic engineering. As a result, a vast lite- ture has been created, though, despite this situation, there is a surprising scarcity of books on the subject. Moreover, those that are available tend to be experimentally oriented, such as, Chemisorption: An Experimental - proach (Wedler 1976). On the theoretical side, The Chemisorption Bond (Clark 1974) provides a good introduction, but is limited in not describing the more advanced techniques presently in use.

College and university faculty find themselves tasked with teaching in the face of ever-changing trends in higher education and constant shifts in the student population. Educators must balance student engagement and retention with their learning and satisfaction in a never-ending cycle of changes in technology, the economy, and the political climate. Even when certain pedagogies or classroom techniques are shown to be beneficial in one discipline, individual faculty may find it challenging to apply them in their own classrooms. This is certainly true in chemistry. Many faculty in chemistry today struggle to embrace research-based educational practices, even those coming out of our own discipline. Graduate programs in chemical education, recent reports on discipline-based education research (1), and an increase in the scholarship of teaching and learning in chemistry indicate a desire among many faculty to change-to reach students in new and exciting ways or to change curricula to better meet students' needs. Faculty are looking for things that work-techniques used by chemists, for chemists. This volume contributes to this on-going conversation. The scholarship presented within this volume is organized in three sections. The first explores innovations found to enhance the learning of typical students as well as those who may be under-prepared. Authors describe their experiences using the flipped classroom and institutional readiness models. The second section provides examples of how technology may be utilized in the chemistry classroom-from e-textbook usage to a computational chemistry program to concrete suggestions for teaching chemistry online. The final section addresses broader issues in chemistry. One chapter demonstrates how to incorporate High-Impact Educational Practices (2) into courses for chemistry majors and nonmajors. A final chapter describes how colleges can adopt the Green Chemistry Commitment. Additionally, contextual information for pedagogical change may be found in the Introduction as well as helpful tips for adopting new approaches.
