Summary: The thermal stability of electroless nickel-phosphorus (Ni-P) film and cobalt-tungsten-phosphorus (Co-W-P) film deposited on GaAs substrate was investigated. The Ni-P film changed from amorphous to crystalline by annealing at 240 degrees C for 1 h, while the crystallinity of the Co-W-P film did not change. The crystallized Ni-P film showed no thickness change and voids formation, indicating the suppression of Ni atom migration, whereas voids were formed in the Co-W-P film due to atom diffusion from the amorphous phase.

Summary: This study demonstrates a new electroless plating method for metallizing plastic 3D printed parts without the use of expensive precious metal catalysts. By electrolessly plating conductive composite filaments, loaded with metal or other conductive particulate, with exposed particles serving as nucleation sites, the researchers achieved successful metalization of plastic parts. The use of a flash of high energy white light to ablate the polymer surface and expose a higher density of metal particulate was also shown to accelerate the plating process. Selective plating using a dual extruder 3D printer was utilized to reduce resistance. The results of this study highlight the importance and potential of this new electroless plating method for the fabrication of conductive composite materials.

Summary: Surface-enhanced Raman spectroscopy (SERS) is a powerful tool in biophysics, bioanalytical chemistry, and biomedicine for monitoring extracellular chemical activity. However, the limited choice of SERS nanotags has hindered its practical application. This study repurposes fluorescent chemosensors as SERS nanotags, using a plasmon-induced reaction to immobilize them onto plasmonic nanostructures. The results demonstrate the successful immobilization and functionality of xanthene-based chemosensors as SERS chemosensors.
