A review on performance optimization and application of ferroelectric thin film materials.
Overcoming thermal quenching is an essential issue in the practical application of luminescent materials. Herein, we found that negative expansion (NTE) can achieve enhancement luminescence molecular materials based on three metal-organic frameworks CuX-bpy (X = Cl, Br, I; bpy 4,4'-bipyridine). All complexes exhibit NTE c-axis, and strongest leads to a contraction Cu...Cu distance CuCl-bpy, which further intensifies emission. This phenomenon indicates existence thermally enhanced charge...
Overcoming thermal quenching is generally essential for the practical application of luminescent materials. It has been recently found that frameworks with negative expansion (NTE) could be a promising candidate to engineer unconventional luminescence enhancement. However, mechanism through which enhancement can well tuned remains an open issue. In this work, enabled by altering ligands in series UiO-66 derived Eu-based metal-organic frameworks, it was revealed changes are closely related...
Rapid progress in modern technologies demands zero thermal expansion (ZTE) materials with multi-property profiles to withstand harsh service conditions. Thus far, the majority of documented ZTE have shortcomings different aspects that limit their practical utilization. Here, we report on a superior isotropic alloy collective properties regarding wide operating temperature windows, high strength-stiffness, and cyclic stability. A boron-migration-mediated solid-state reaction (BMSR) constructs...
Abstract Negative thermal expansion (NTE) alloys possess great practical merit as offsets for positive due to its metallic properties.

Deciphering the three-dimensional (3D) insight into nanocatalyst surfaces at atomic level is crucial to understanding catalytic reaction mechanisms and developing high-performance catalysts. Nevertheless, better inherent insufficiency of a long-range ordered lattice in nanocatalysts big challenge.

To evaluate the diagnostic value and characteristic features of FCD epileptogenic zones using a novel sequence called fluid white matter suppression (FLAWS). Thirty-nine patients with pathologically confirmed good surgery outcomes (class I or II, according to Engel Epilepsy Surgery Outcome Scale) were retrospectively included in study. All underwent preoperative whole-brain MRI examination that conventional sequences (T2WI, T1WI, two-dimensional (2D) axial, coronal fluid-attenuated inversion...
Zero thermal expansion (ZTE) alloys as dimensionally stable materials are usually challenged by harsh environmental erosion, since ZTE and corrosion resistance generally mutually exclusive. Here, a high-performance alloy, Zr0.8 Ta0.2 Fe1.7 Co0.3 , is reported, that shows isotropic behavior (αl = 0.21(2) × 10-6 K-1 ) in wide temperature range of 5-360 K, high seawater-like solution compared with classic Invar stainless Invar, excellent cyclic structural stabilities. Such stabilities...
Metallic phase (1T) MoS2 has been regarded as an ideal catalytic material for the hydrogen evolution reaction (HER) due to its high active site density and favorable electrical conductivity. However, preparation of 1T-phase samples requires tough conditions 1T-MoS2 poor stability under alkaline conditions. In this work, 1T-MoS2/NiS heterostructure catalysts grown in situ on carbon cloth were prepared by a simple one-step hydrothermal method. The obtained MoS2/NiS/CC combines advantages...
