Upon focusing a near-infrared laser beam onto the glass/solution interface, a single liquid droplet is formed due to optical trapping and a photothermal effect. The resultant droplet deposits on the substrate, exhibiting a hemispherical shape. The hemispherical droplet can extract and condense molecules due to high ionic liquid concentration, which is confirmed by Raman and fluorescence spectroscopic analysis. The current approach offers a new methodology with which to collect and perform microanalysis on tiny amounts of substances.

Their photocatalytic activities being evaluated in accordance with ISO 22197–1 : 2016 protocol under UV and visible light. The samples exhibiting the highest performance were produced by co-precipitation, showing ~7 % NO and ~2 % NO<sub>x</sub> removal under visible light and ~19 % NO and ~10 % NO<sub>x</sub> removal under UV light.

The gradual change in solid state emission color from yellowish green to cyan was observed in the ground matrices of zinc acetate salt with varied amounts of TBA-2HP. Furthermore, the electroluminescence properties of the TBA-2HP were investigated by fabricating the TBA-2HP-doped polymer on the surface of a near-ultraviolet (NUV) and blue light-emitting diode (LED). The TBA-2HP displayed green light emission upon coating a thin layer of TBA-2HP-doped polymer over the surface of a NUV LED bulb and white light emission upon coating a thin layer of TBA-2HP along with a red phosphor-doped polymer on the surface of a blue LED bulb.
