High‐Precision Measurement of Time Delay with Frequency‐Resolved Hong‐Ou‐Mandel Interference of Weak Coherent States

Advanced Quantum Technologies, EarlyView.
High‐precision time‐delay measurements are demonstrated using frequency‐resolved Hong‐Ou Mandel (HOM) interference with weak coherent states. The method, by exploiting the quantum eraser phenomenon, achieves low uncertainty even for delays exceeding the photon coherence time, where traditional HOM interferometry fails, thus confirming theoretical ...

Topological‐defect‐featured order evolution of liquid crystals

Responsive Materials, EarlyView.
This review provides a comprehensive introduction to the recent advances in the topological‐defect‐featured order evolution of liquid crystal (LCs), including the stimulus‐driven dynamics of defects in nematic LCs, topological defect morphological transformation during phase transitions, advanced strategies for regulating and applications of ...

Engineered Gravel Trench Hyporheic Exchange to Create Cold‐Water Thermal Refuges

River Research and Applications, EarlyView.
ABSTRACT Warming rivers are driving a loss or fragmentation of cold‐water habitat and providing the impetus to develop proactive thermal management approaches to maintain suitable habitat in rivers. One innovative approach is through the creation of cold‐water thermal refuges during periods of thermal stress for aquatic species.

Symmetric Metal Organic Framework‐Plasmonic Architectures for Reversible and High‐Sensitivity Optical Sensing

Small, EarlyView.
This work presents a plasmonic sensing platform combining surface lattice resonances (SLRs) in 2D metal nanoparticle gratings with ZIF‐8 MOF films. The plasmonic grating is easily and scalably produced from template‐assisted assembly of metal colloids, which is fully compatible with MOF growth. The resulting MOF‐plasmonic structure allows for a dynamic

Unlocking Klockmannite: Formation of Colloidal Quasi‐2D CuSe Nanocrystals and Photo‐Physical Properties Arising From Crystal Anisotropy

Small, EarlyView.
Thiol‐free hot injection approach yields quasi‐2D klockmannite CuSe nanocrystals, specifically nanosheets and uniform triangular nanoplatelets. This study reconsiders the klockmannite from the point of view of crystal anisotropy and demonstrates its effect on plasmonic response in the near‐infrared spectral region with the theoretical emergence of ...
