Review of millimeter‐wave and terahertz near‐field synthetic aperture radar imaging technology
InfoScience, EarlyView.Abstract This paper comprehensively reviews the development of millimeter‐wave (MMW) and terahertz (THz) near‐field imaging technologies, with an emphasis on the state of synthetic aperture radar (SAR)‐based imaging technologies. Near‐field imaging technologies are categorized into passive and active imaging modes, among which active imaging is favored

A personal 360° view of applications of ‘biomimetic’ molecular recognition
Journal of Chemical Technology &Biotechnology, EarlyView.Abstract Molecular recognition between biological molecules has formed the basis for innumerable applications in biotechnology for the last seven decades or so. Techniques such as affinity chromatography, solid‐phase and aqueous two‐phase extraction, affinity precipitation, biomimetic catalytic systems, biosensors and molecular imprinting all exploit ...

Real‐Time Probing of Complex Bi‐Periodic Self‐Organized Grating Formation via Small‐Angle Scattering
Nano Select, EarlyView.A wedge‐shaped AgCl nanolayer with a granular Ag film enables the self‐organization of bi‐periodic nanostructures. Real‐time SAS pattern analysis reveals dynamic domain interactions and competing gratings, validating a generator/re‐emitter model driven by TEn mode excitations. This framework offers a novel approach for evaluating SPN formation quality.

Anticlastic Curvature and Material Freedom
physica status solidi (b), EarlyView.Anticlastic curvature occurs in bent bars for positive Poisson's ratio; synclastic curvature occurs for negative Poisson's ratio provided the material is homogeneous and elastic. Some planar negative Poisson's ratio materials exhibit anticlastic saddle curvature rather than convex curvature in bending due to effects of 3D structure.
