The book presents innovative techniques for low-cost nanofabrication of large-area plasmonic nanostructures, utilizing hole-mask colloidal lithography and nanosphere lithography. It details the step-by-step fabrication process, employing thin film PMMA-gold hole-masks and polystyrene nanosphere monolayers to create complex shapes. Applications include advanced sensing methods, such as antenna-assisted surface-enhanced infrared absorption for molecule detection and high-sensitivity localized surface plasmon resonance sensing for liquids and gases, along with the development of multifunctional metasurfaces.

The book explores the construction of signatures for curves and surfaces, focusing on both smooth and discrete cases. It emphasizes the identification of differential and discrete invariants as coordinates for these signatures. The study delves into variational problems related to smooth and B-spline approximated curves, particularly in the context of curve completion in 2D and 3D. Solutions to the Euler-Lagrange equations are examined, along with aesthetically pleasing discrete solutions. Additionally, it discusses the integration of moving frames with Conformal Geometric Algebra for solving curve completion issues.

Focusing on Tianjin, a representative city in China, this book examines the intricate relationship between environmental regulation and economic productivity amidst rapid development. It highlights how traditional industrial growth models have led to significant environmental pollution, surpassing the ecosystem's capacity to cope. By analyzing recent economic data, the study explores various growth models and their effects on total factor productivity, technological innovation, and spatial correlation, ultimately revealing the critical role of environmental regulation in achieving sustainable regional development.
