Nano- and microplastic particles are a global and emerging environmental issue that might pose potential threats to human health. The present work exploits artificial intelligence (AI) to identify nano- and microplastics in water by monitoring the interaction of the sample with a sensitive surface. An estrogen receptor (ER) grafted onto a gold surface, realized on a nonexpensive and easy-to-produce plastic optical fiber (POF) platform in order to excite a surface plasmon resonance (SPR) phenomenon, has been developed in order to carry out a "smart" sensitive interface (ER-SPR-POF interface). The ER-SPR-POF interface offers output data useful for exploiting a machine learning-based approach to achieve nano- and microplastic particle sensors. This work developed a proof-of-concept sensor through a training phase carried out by different particles, in terms of materials and size. The experimental results have demonstrated that the proposed "smart" ER-SPR-POF interface combined with AI can be used to identify the kind of particles in terms of the materials (polystyrene; poly(methyl methacrylate)) and size (20 μm; 100 nm) with an accuracy of 90.3%.
The presence of a 8% wt N^C^N-Pt( ii ) complex bearing mesityl groups on pyridines leads to an efficient blue-emitting OLED with CIE coordinates of (0.13, 0.29).
Metal–organic chemical vapor deposition has been applied to produce europium-doped BaF 2 thin films on silicon and quartz substrates. A combined experimental and theoretical study has proved the downshifting properties of the film.

Triiodide (I3−) is a species well-known to influence the nature of perovskite materials. Here, we highlight possible and unexpected sources of I3−, i.e. the iodide (I−) salt solutions used for the synthesis of metal-halide perovskites.
