Unraveling Surface Reconstruction of MOF-Derived La, P-CoO for Energy-Efficient Water and Urea Electrolysis.

Constructing robust electrocatalysts and shedding light on the processes of surface reconstruction is crucial for sustained hydrogen production and a deeper understanding of catalytic behavior. Here, a novel ZIF-67-derived lanthanum- and phosphorus-co-doped CoO catalyst (La, P-CoO) has been reported. X-ray absorption spectroscopy (XAS) confirms that the La and P co-doping reduces the coordination number (CN), improves oxygen vacancies (O), and leads to lattice distortion.

A Review on the Recent Advancements of Polymer-Modified Mesoporous Silica Nanoparticles for Drug Delivery Under Stimuli-Trigger.

Mesoporous silica nanoparticles (MSNs) are gaining popularity in nanomedicine due to their large surface area, variable pore size, great biocompatibility, and chemical adaptability. In recent years, the combination of smart polymeric materials with MSNs has transformed the area of regulated drug administration, particularly under stimuli-responsive settings. Polymer-modified MSNs provide increased stability, longer circulation times, and, most crucially, the capacity to respond to diverse internal (pH, redox potential, enzymes, and temperature) and external (light, magnetic field, and ultrasonic) stimuli.
