When did China make the decisive turn from tradition to modernity? For decades, the received wisdom would have pointed to the May Fourth movement, with its titanic battles between the champions of iconoclasm and the traditionalists, and its shift to more populist forms of politics. A growing body of recent research has, however, called into question how decisive the turn was, when it happened, and what relation the resulting modernity bore to the agendas of people who might have considered themselves representatives of such an iconoclastic movement. Having thus explicitly or implicitly 'decentered' the May Fourth, such research (augmented by contributions in the present volume) leaves us with the task of accounting for the shape Chinese modernity took, as the product of dialogues and debates between, and the interplay of, a variety of actors and trends, both within and (certainly no less importantly) without the May Fourth camp.

Electronic Structure and Surfaces of Sulfide Minerals: Density Functional Theory and Applications examines the mineral structure and electronic properties of minerals and their relationship to mineral floatability by density functional theory (DFT). This pragmatic guide explores the role of minerals in flotation by focusing on the mineral surface structure, electronic properties, and the adsorption of flotation agents through the study of the microscopic mechanism of reagents from the structure and properties of minerals. The flotation mechanism is explained from the point-of-view of solid physics, which is of great significance for both theoretical research and practical applications. The study of the structure and properties of the minerals can reveal the essential nature of mineral flotation, hence why minerals have floatability, the mechanism of response of different minerals to different chemicals, and the origin of the selectivity of flotation agents.
