In this thesis, the author outlines the construction of active structure and modulation of catalytic reactivity of Pt-based bi-component catalysts, from the model systems to real supported catalysts. The thesis investigates the promotion effect of the second components on catalytic performance of Pt catalysts, and presents the reversible generation of the “sandwich-like” structure of Pt-Ni catalysts, containing both surface NiO1-X and subsurface Ni by alternating redox treatments at medium temperature. With the aid of single layer graphene, the dynamic process of chemical reactions occurring on the Pt(111) surface can be visualized using in-situ LEEM and DUV-PEEM techniques, the results of which are included here. The author reveals that the graphene layer exhibits a strong confinement effect on the chemistry of molecules underneath and the intercalated CO can desorb from the Pt surface around room temperature and in UHV, which may promote the CO oxidation confined under graphene.
The CCN family of genes currently comprises six secreted proteins (designated CCN16 i.e., Cyr61/CCN1; ctgf/CCN2; Nov/CCN3; WISP1/CCN4; WISP2/CCN5, and WISP3/CCN6) showing a strikingly conserved primary structure, with four modules sharing partial identity with IGF binding proteins, Von Willebrand protein, thrombospondin and several matricellular proteins and growth factors. The current view is that CCN proteins modulate signaling pathways that involve regulatory components of the extracellular matrix. As such, they likely act as a central hub in the regulation of mitosis, adhesion, apoptosis, extracellular matrix production, growth arrest and migration of multiple cell types. The 5th interna...
Chinese External Medicine is the branch of TCM concerned with diagnosis and treatment of conditions that affect the body’s surface, unlike TCM Internal Medicine whereby the focus is on internal organ systems. External medicine, or wai ke, refers to conditions that can be seen by the eye or palpated directly such as traumatic injuries, skin diseases, breast lumps, hemorrhoids, male genital problems and so on. Despite the common nature of many conditions covered by Chinese external medicine, until the publication of this book, little had been done to introduce these essential diagnostic and treatment methods to the West. Eight chapters in the text are devoted to the diagnosis and treatment o...
Methodology and applications of redox proteomics The relatively new and rapidly changing field of redox proteomics has the potential to revolutionize how we diagnose disease, assess risks, determine prognoses, and target therapeutic strategies for people with inflammatory and aging-associated diseases. This collection brings together, in one comprehensive volume, a broad array of information and insights into normal and altered physiology, molecular mechanisms of disease states, and new applications of the rapidly evolving techniques of proteomics. Written by some of the finest investigators in this area, Redox Proteomics: From Protein Modifications to Cellular Dysfunction and Diseases exami...
This book highlights the recent advances in nanotheranostics from basic research to potential applications, and discusses the modular design and engineering of multiplex nanoparticles including gold nanostructures, luminescent nanoparticles, dendrimers and liposomes. Each chapter demonstrates multifunctional nanoparticles with topics covering targeting, imaging, delivery, diagnostics, and therapy as new modalities for cancer theranostics. This comprehensive book presents expert views on the latest developments in theranostic nanomedicine. It focuses on potential theranostic applications of multifunctional nanoparticles ranging from identifying noninvasively cancer cells by molecular detection, and visualizing in vivo drug delivery by means of contrast enhanced imaging, to destroying cancer cell s with minimal side effects via selective accumulation at tumor sites, and real-time monitoring therapeutic effectiveness. It also presents an interdisciplinary survey of nanotheranostics and as such is a valuable resource for researchers and students in related fields. Zhifei Dai is a Professor at the Department of Biomedical Engineering, College of Engineering, Peking University, China.
Despite Asia’s rapid growth, vast sections of its population still live in poverty and suffer hunger and other forms of deprivation. Merely relying on Asia’s growth will not help the deprived see a better future in their lifetimes. Ways must be found to make growth more inclusive combined with proactive public action to bring substantial improvements in the lives of Asia’s deprived people. This book is written by a set of experts who have been working long on reducing various aspects of human deprivations in Asia. It begins with a discussion of the massive dimensions of deprivations that continue to exist in Asia. Although many countries have adopted inclusive growth strategies to enab...
Increasingly, students worldwide are seeking post-secondary education to acquire new skill-sets and credentials. There is an explosion of community college models that provide educational opportunities and alternative pathways for students who do not fit the traditional higher educational profile. This book focuses on economic models to help local and national economies develop strong workforce training, humanitarian models to bring about social mobility and peace, transformative models to help institutions expand and keep up with societal needs, and newly created models that respond to the educational and training needs of a constantly changing world. These models seek to capture the imagination of those who are committed to learning about what works in higher education and in particular, the impact community college models are having on the changing nature of world social, political and economic landscapes. With contributors representing 30 countries, this book presents an international perspective.
Today’s academic revolution is unprecedented. Mass higher education has become a worldwide phenomenon, with enrollments growing from 100 million to 150 million in just a decade. The implications of massification are immense—greatly increased participation for a more diverse population including women and many traditionally underrepresented socio-economic groups; the rise of private higher education; diversification of academic institutions and systems; and an overall weakening of academic standards at non-elite institutions in many countries. At the same time, higher education is recognized as a key driver of the new knowledge economy. Because of this research universities, at the top of...
In recent years, there has been a dramatic increase in grain-based fuel ethanol production in North America and around the world. Whether such production will result in a net energy gain or whether this is sustainable in the long term is under debate, but undoubtedly millions of tons of non-fermented residues are now produced annually for global tr
