A Fully‐Connected Chip‐Integrated Reconfigurable Mode‐Pairing Quantum Key Distribution Network

Laser &Photonics Reviews, EarlyView.
This work constructs a fully connected reconfigurable chip‐integrated quantum key distribution network via the mode‐pairing protocol. Hybrid ECL and WSS chips cut wavelength and port overhead, realizing arbitrary‐user key sharing with merely two wavelengths.

The statistical mechanics of Twitter communities

, 2019
We build models for the distribution of social states in Twitter communities. States can be defined by the participation vs silence of individuals in conversations that surround key words, and we approximate the joint distribution of these binary ...

Machine learning‐driven advances in carbon‐based quantum dots: Opportunities accompanied by challenges

Responsive Materials, EarlyView.
Machine learning provides a unifying framework to connect structure, fluorescence properties, and applications of carbon‐based quantum dots. This review highlights how data‐driven strategies enable fluorescence regulation, reveal underlying mechanisms, and accelerate the rational design of functional carbon dots.

A study of superconductivity in single crystals and thin films using muon-spin rotation and neutron scattering [PDF]

, 2009
The archetypal high temperature superconductor Bi₂Sr₂CaCu₂O[subscript[8+δ]] has been extensively investigated. However, until now, little has been known about the behaviour of the magnetic vortices inside the Vortex Glass and liquid state.

Seeded‐Growth of ZIF‐8 onto Magnetic Nanoparticles: Smart Nanocarriers with Ultrahigh Drug Loading for AMF‐Triggered Release

Small, EarlyView.
We developed core‐shell iron oxide@ZIF‐8 magnetic‐MOF nanohybrids via a seeded growth method for magnetic hyperthermia‐triggered drug delivery. Cubic cores and thinner shells maximized heating. In‐situ doxorubicin encapsulation achieved 98% loading, better than surface encapsulation. Polymer coating improved stability.

Scaling Laws for Hairy Nanoparticle in Good Solvent

, 2014
Scaling behavior of Hairy Nanoparticle in good solvent is studied by means of Dissipative Particle Dynamics (DPD). We studied gold spherical nanoparticle (Au) decorated by poly (styrene-b-2-vinylpyridine) (PS-PVP) diblock copolymer with PVP block ...

Scalable Room‐Temperature Terahertz Graphene Cameras

Small Methods, EarlyView.
ABSTRACT Terahertz (THz) imaging has emerged as a powerful tool for non‐destructive, label‐free analysis across several scientific disciplines, ranging from materials science to biomedical research. By capturing the spatial‐dependent information in a broad range of frequencies, this technique enables the identification of chemical composition ...

Research Progress in Treeing Phenomena of Polypropylene Insulation Materials

High Voltage, EarlyView.
ABSTRACT Polypropylene (PP) is increasingly utilised in high‐voltage systems due to its superior electrical and thermal properties. However, electrical treeing poses a significant threat to its long‐term reliability, potentially leading to insulation failure.

Regulating critical technologies: National security and intellectual property

The Journal of World Intellectual Property, EarlyView.
Abstract In recent years, claims of ‘national security’ have surged internationally to protect various security interests including public health, economic security and cybersecurity. National industrial strategies for building critical technologies challenge the scope of ‘national security’ in international intellectual property (IP) protection ...

Macroscopic to ultrastructural analyses identify the loss of myofibrils as the primary mediator of ageing‐ and disuse‐induced muscle fibre atrophy

The Journal of Physiology, EarlyView.
Abstract figure legend Skeletal muscle structure was analysed at three levels in young vs. aged humans, and in young vs. aged mice subjected to unilateral hindlimb immobilization to model disuse. (1) Macroscopic: magnetic resonance imaging of the thigh (human) and wet mass of individual hindlimb muscles (mouse) revealed that both ageing and disuse ...
