Open AccessExtraordinary high ductility/strength of the interface designed bulk W-ZrC alloy plate at relatively low temperature
The refractory tungsten alloys with high ductility/strength/plasticity are highly desirable for a wide range of critical applications. Here we report an interface design strategy that achieves 8.5 mm thick W-0...

Open AccessOn the Chemistry and Physical Properties of Flux and Floating Zone Grown SmB6 Single Crystals
Recent theoretical and experimental findings suggest the long-known but not well understood low temperature resistance plateau of SmB6 may originate from protected surface states arising from a topologically non-...

Open AccessA novel laser-collider used to produce monoenergetic 13.3 MeV 7Li (d, n) neutrons
Neutron energy is directly correlated with the energy of the incident ions in experiments involving laser-driven nuclear reactions. Using high-energy incident ions reduces the energy concentration of the gener...

Open AccessEstrogen/ERR-α signaling axis is associated with fiber-type conversion of upper airway muscles in patients with obstructive sleep apnea hypopnea syndrome
Estrogen is related with the low morbidity associated with obstructive sleep apnea hypopnea syndrome (OSAS) in women, but the underlying mechanisms remain largely unknown. In this study, we examined the relati...

Open AccessAtomic-resolved depth profile of strain and cation intermixing around LaAlO3/SrTiO3 interfaces
Novel behavior has been observed at the interface of LaAlO3/SrTiO3 heterostructures such as two dimensional metallic conductivity, magnetic scattering and superconductivity. However, both the origins and quantifi...

Open AccessInverse Doppler Effects in Broadband Acoustic Metamaterials
The Doppler effect refers to the change in frequency of a wave source as a consequence of the relative motion between the source and an observer. Veselago theoretically predicted that materials with negative r...

Open AccessSlowing down light using a dendritic cell cluster metasurface waveguide
Slowing down or even stop** light is the first task to realising optical information transmission and storage. Theoretical studies have revealed that metamaterials can slow down or even stop light; however, ...

Open AccessImproving the photovoltaic performance of perovskite solar cells with acetate
In an all-solid-state perovskite solar cell, methylammonium lead halide film is in charge of generating photo-excited electrons, thus its quality can directly influence the final photovoltaic performance of th...

Open AccessQuasi mode-locking of coherent feedback random fiber laser
Mode-locking is a milestone in the history of lasers that allows the generation of short light pulses and stabilization of lasers. This phenomenon is known to occur only in standard ordered lasers for long tim...

Open AccessDevelopment of interface-dominant bulk Cu/V nanolamellar composites by cross accumulative roll bonding
Traditional nanostructured metals are inherently comprised of a high density of high-energy interfaces that make this class of materials not stable in extreme conditions. Therefore, high performance bulk nanos...

Open AccessImproving superconductivity in BaFe2As2-based crystals by cobalt clustering and electronic uniformity
Quantum materials such as antiferromagnets or superconductors are complex in that chemical, electronic, and spin phenomena at atomic scales can manifest in their collective properties. Although there are some ...

Open AccessMitsugumin 29 regulates t-tubule architecture in the failing heart
Transverse tubules (t-tubules) are uniquely-adapted membrane invaginations in cardiac myocytes that facilitate the synchronous release of Ca2+ from internal stores and subsequent myofilament contraction, although...
