Proposal for a loophole-free Bell test based on spin-photon interactions in cavities
We present a scheme to demonstrate loophole-free Bell inequality violation
where the entanglement between photon pairs is transferred to solid state
(spin) qubits mediated by cavity QED interactions. As this transfer can be
achieved in a heralded way, our scheme is basically insensitive to losses on
the channel. This makes it appealing for the implementation of quantum
information protocols based on nonlocality, such as device-independent quantum
key distribution. We consider potential experimental realisations of our scheme
using single atom, colour centre and quantum dot cavity systems.Comment: 7 pages, 4 figure
VPS35 haploinsufficiency increases Alzheimer’s disease neuropathology
The retromer complex component VPS35 prevents activation of the BACE1 and Aβ production and thus plays an essential role in limiting Alzheimer’s disease neuropathology

An Ultrahigh Sensitivity Acetone Sensor Enhanced by Light Illumination
Au:SmFe0.9Zn0.1O3 is synthesized by a sol-gel method and annealed at 750 °C. Through XRD, SEM and XPS analysis methods, the microstructure of the material has been observed. The average particle size is about 50 nm. The sensor shows a high sensitivity toward acetone vapor. As the relative humidity increases, the resistance and sensitivity of the sensor decline. To obtain a low optimum operating temperature, light illumination with different wavelengths has been introduced. The sensitivity toward acetone is improved at lower operating temperature when the sensor is irradiated by light. The smaller the wavelengths, the better the sensitivity of the sensor. Compared with other gases, the sensor shows excellent selectivity to acetone vapor, with better sensitivity, selectivity and stability when under light illumination
Fabrication and characterization of highly thermal conductive Si3N4/diamond composite materials
A novel composite materials using silicon nitride (Si3N4) as the substrate and diamond particles as the reinforcement phase were developed to increase both thermal conductivity and mechanical properties. The Ti coating on the surfaces of the diamond particles facilitated the formation of a titanium carbonitride (TiCiN1-i) interface between the two constituents during sintering, creating a strong bonding for high thermal conduction at the diamond-Si3N4 interface and inhibiting the graphitization of diamond during the sintering process. Furthermore, a sandwiched material design was made whereby Si3N4 and Si3N4/Ti-coated diamond layers were stacked alternately to endow the composites with a directional heat conduction characteristic. The thermal conductivity of the fabricated Si3N4/diamond composites increased by up to 272.87 % compared to that of commercially available Si3N4, making them excellent candidates for thermal management materials required in high-performance electronic devices
