Piezoresistive MOF for Intraocular Pressure Monitoring.

Continuous monitoring of intraocular pressure (IOP) is critical for the diagnosis and management of glaucoma. Flexible piezoresistive wearable devices, featuring high sensitivity and simple signal processing, enable such continuous monitoring. Recently, conductive metal-organic frameworks (MOFs) have shown promising potential in electronic devices due to their coordination self-assembly, which allows integration with various complex substrates for wearable sensor applications.

Formation of calcium carbonate nanoparticles through the assembling effect of glucose and the influence on the properties of PDMS.

In order to prepare calcium carbonate nanoparticles in a green and environmentally friendly way, the concept of bio-mineralization has been proposed. Glucose, as a common small molecular organic substance found in organisms, participates in the mineralization process in cells. By adding glucose as a chemical additive, long chains of calcium carbonate form at the initial stage and then break granularly over-carbonation.

In-situ growth of core-shell ZnFeO @ porous hollow carbon microspheres as an efficient microwave absorber.

The special structure and composition are the important factors that determine the microwave absorption properties. In this study, the porous hollow carbon microsphere (PHCMS) is synthesized by the self-assembly technology, and ZnFeO particles are synthesized inside the carbon sphere by in-situ preparation with taking advantage of the porous and hollow characteristics of the carbon sphere, which prepares ZnFeO@PHCMS composite material. The composite shows good performance in terms of minimum reflection loss and absorption bandwidth.
