Hydrostatic pressure, as an alternative of chemical pressure to tune the crystal structure and physical properties, is a significant technique for novel function material design fundamental research. In this article, we report phase stability visible light response organolead bromide perovskite, CH3NH3PbBr3 (MAPbBr3), under hydrostatic up 34 GPa at room temperature. Two transformations below 2 (from Pm3̅m Im3̅, then Pnma) reversible amorphization starting from about were observed, which...
Heart failure (HF) is the end-stage of cardiovascular diseases, which associated with a high mortality rate and readmission rate. Household early diagnosis real-time prognosis HF at bedside are significant importance. Here, we developed highly sensitive quantitative household platform (termed as UC-LFS platform), integrating smartphone-based reader multiplexed upconversion fluorescent lateral flow strip (LFS). Dual-color core–shell nanoparticles (UCNPs) were synthesized probes for...

The discovery of iron-based superconductors (FeSCs), with the highest transition temperature (Tc) up to 55 K, has attracted worldwide research efforts over past ten years. So far, all these FeSCs structurally adopt FeSe-type layers a square iron lattice and superconductivity can be generated by either chemical doping or external pressure. Herein, we report observation in an honeycomb via pressure-driven spin-crossover. Under compression, layered FePX3 (X = S, Se) simultaneously undergo large...
Graphitic carbon nitrides have appeared as a new type of photocatalyst for water splitting, but their broader and more practical applications are oftentimes hindered by the insolubility or difficult dispersion material in solvents. We herein prepared novel two-dimensional (2D) nitride-type polymers doped iron under mild one-pot method through preorganizing formamide citric acid precursors into supramolecular structures, which eventually polycondensed homogeneous organocatalyst highly...
Spin-crossover (SCO) is generally regarded as a spectacular molecular magnetism in 3d4-3d7 metal complexes and holds great promise for various applications such memory, displays, sensors. In particular, SCO materials can be multifunctional when classical light- or temperature-induced occurs along with other cooperative structural and/or electrical transport alterations. However, has rarely been observed condensed matter under hydrostatic pressure (an alternative external stimulus to light...
In nucleic acid testing (NAT), gold nanoparticle (AuNP)-based lateral flow assays (LFAs) have received significant attention due to their cost-effectiveness, rapidity, and the ability produce a simple colorimetric readout. However, poor sensitivity of AuNP-based LFAs limits its widespread applications. Even though various efforts been made improve assay sensitivity, most methods are inappropriate for integration into LFA sample-to-answer NAT at point-of-care (POC), usually complicated...
Paper-based devices have been broadly used for the point-of-care detection of dengue viral nucleic acids due to their simplicity, cost-effectiveness, and readily observable colorimetric readout. However, moderate sensitivity functionality limited applications. Despite above-mentioned advantages, paper substrates are lacking in ability control fluid flow, contrast flow enabled by polymer (e.g., agarose) with tunable pore size porosity. Herein, taking benefits from both materials, authors...
Hepatitis B virus (HBV) infection is a serious public health problem, which can be transmitted through various routes (e.g., blood donation) and cause hepatitis, liver cirrhosis cancer. Hence, it necessary to do diagnostic screening for high-risk HBV patients in these transmission routes. Nowadays, protein-based technologies have been used testing, however involve the issues of large sample volume, antibody instability poor specificity. Nucleic acid hybridization-based lateral flow assay...
