The adsorption behavior of Eu(III) onto silica surface, which was partially coated with Fe(III) or Ti(IV), was investigated to determine Fe(III) or Ti(IV) effects on the surface reaction of lanthanides on mineral surfaces in groundwater. Compared with a parallel uncoated silica, the Fe(III)-coated silica did not enhance the adsorption of Eu(III). However, enhanced adsorption of Eu(III) on the Ti(IV)-coated silica was observed by increasing the amount of Ti(IV) on the silica surface.

Plasmon resonance plays an important role in improving the detection of biomolecules, and it is one of the focuses of research to use metal plasmon resonance to achieve fluorescence enhancement and to improve detection sensitivity. However, the problems of nondynamic tuning and fluorescence quenching of metal plasmon resonance need to be solved. Graphene surface plasmon resonance can be dynamically controlled, and the graphene adsorption of fluorescent molecules can avoid fluorescence quenching and greatly improve the fluorescence emission intensity.

Metal halide perovskites (MHPs) have attracted significant attention owing to their simple manufacturing process and unique optoelectronic properties. Their reversible electrical or optical property changes in response to oxidizing or reducing environments make them prospective materials for gas detection technologies. Despite advancements in perovskite-based sensor research, the mechanisms behind perovskite-gas interactions, vital for sensor performance, are still inconclusive.

Density functional theory (DFT) combined with the Viennasimulation package (VASP) was used to investigate the electronic, magnetic, and optical properties of one-dimensional stanene nanoribbons (SnNRs) and Na, Mg, and Al-adsorbed SnNRs. The SnNRs, with a width of 10 Sn atoms and hydrogen-passivated edges, retained their hexagonal honeycomb structure after structural optimization. Both pristine and adsorbed SnNRs exhibit narrow band gap semiconducting behavior, with pristine SnNRs being non-magnetic and adsorbed SnNRs showing non-zero magnetic moments.

Polyvinylpyrrolidone K30 was used as the templating agent, and ammonium bicarbonate was used as the pore-forming agent to make porous mannitol and porous lactose by the template and pore-forming agent method, respectively. Compared with the template method, the porous particles prepared by the pore-forming agent method have larger pore diameter (320.276 nm and 250.
