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 ...

Boltzmann Entropy, the Holographic Bound and Newtonian Cosmology
Proceedings, 2017 The holographic principle sets an upper bound on the total (Boltzmann) entropy content of the Universe at around 10 123 k B ( k B being Boltzmann’s constant).

Gravitation, Holographic Principle, and Extra Dimensions
Journal of Modern Physics, 2016 Within the context of Newton's theory of gravitation, restricted to point-like test particles and central bodies, stable circular orbits in ordinary space are related to stable circular paths on a massless, unmovable, undeformable vortex-like surface, under the action of a tidal gravitational field along the symmetry axis.

Coherence‐Gated Mirau Interferometry for Single‐Shot Quantitative Phase Imaging and Motion Sensing
Laser &Photonics Reviews, EarlyView.This paper presents a compact add‐on module converting a Mirau or other on‐axis interferometer into a single‐shot quantitative phase imaging system using coherence gating and precise optical path matching. Demonstrations include time‐resolved imaging of human cells and streaming red blood cells, visualization of evaporation dynamics in liquid mixtures,

A Thermodynamic Approach to Holographic Dark Energy
Advances in High Energy Physics, 2017 We propose a method to relate the holographic minimal information density to de Broglie’s wavelength at a given universe temperature T. To figure this out, we assume that the thermal length of massive and massless constituents represents the cut-off ...

Responsive Materials, EarlyView.We reported a stress‐guided photo‐programming strategy that enables cholesteric liquid crystal elastomers (CLCEs) to achieve synchronous 3D shape morphing and structural color evolution from a single 2D film. Abstract Flexible materials with dynamic structural colors have attracted considerable interest for multilevel information interaction, showing ...
