Supramolecular Rotor Assembly for the Design of a Hybrid Ferroelectric-Antiferromagnetic Multiferroic Semiconductor.

Ferroelectric (FE)-antiferromagnetic (AFM) multiferroic materials have sparked growing interest due to their huge possibilities in energy-saving, photoelectric devices, nonvolatile storage, and switches. However, realizing FE-AFM properties in a hybrid molecular material is difficult because ferroelectric and magnetic orders are commonly mutually exclusive. Here, we report an FE-AFM multiferroic semiconductor [NH(18-crown-6)][Mn(SCN)] (NCMS) by supramolecular assembly approach via molecular rotor synthon [NH(18-crown-6)] and inorganic magnetic module [Mn(SCN)].

Molecular Engineering Regulation Achieving Out-of-Plane Polarization in Rare-Earth Hybrid Double Perovskites for Ferroelectrics and Circularly Polarized Luminescence.

Out-of-plane polarization is a highly desired property of two-dimensional (2D) ferroelectrics for application in vertical sandwich-type photoferroelectric devices, especially in ultrathin ferroelectronic devices. Nevertheless, despite great advances that have been made in recent years, out-of-plane polarization remains unrealized in the 2D hybrid double perovskite ferroelectric family. Here, from our previous work 2D hybrid double perovskite HQERN ((S3HQ)EuRb(NO), S3HQ=S-3-hydroxylquinuclidinium), we designed a molecular strategy of F-substitution on organic component to successfully obtain FQERN ((S3FQ)EuRb(NO), S3FQ=S-3-fluoroquinuclidinium) showing circularly polarized luminescence (CPL) response.

Effects and safety of massage therapy for patients with metatarsal pain: A protocol for systematic review and meta-analysis.

Background: Metatarsalgia refers to localized or generalized forefoot pain in the region of the metatarsal heads. Often this pain is plantar, beneath the metatarsal heads, and arises from either mechanical or iatrogenic causes. The treatment of metatarsalgia remains controversial.

Effects of massage therapy for patients with thoracic facet joint disorders: A protocol for systematic review and meta-analysis.

Background: Thoracic facet joint disorder is a common thoracic disorder in clinic, inducing pain and discomfort at the dislocated thoracic vertebrae, radiating to pain of the neck and back. The incidence of thoracic facet joint disorder is higher than the facet disorder of the cervical and lumbar vertebrae. Therefore, an ideal strategy to relieve thoracic facet joint disorder is urgently needed.

Lateral flow immunoassay for quantitative detection of ractopamine in swine urine.

A strip reader based lateral flow immunoassay (LFIA) was established for the rapid and quantitative detection of ractopamine (RAC) in swine urine. The ratio of the optical densities (ODs) of the test line (AT) to that of the control line (AC) was used to effectively minimize interference among strips and sample variations. The linear range for the quantitative detection of RAC was 0.
