The problem of antibiotic abuse and drug resistance is becoming increasingly serious. In recent years, polydopamine (PDA) nanoparticles have been recognized as a potential antimicrobial material for photothermal therapy (PTT) due to their excellent photothermal conversion efficiency and unique antimicrobial ability. PDA is capable of rapidly converting light energy into heat energy under near-infrared (NIR) light irradiation to kill bacteria efficiently.

Cartilage is a connective tissue composed of mainly water, collagen (COL) and proteoglycans (PGs) including chondroitin sulfate (CS). Near-infrared (NIR) spectroscopy is adequate for examination of soft and hard tissues with large amount of water non-destructively and non-invasively. We measured tablets containing CS and COL using NIR spectroscopy to develop an evaluation method for PGs in cartilage non-destructively and non-invasively.

Water electrolysis is a green method of storing electrical energy in the chemical bonds of high-energy hydrogen gas (H). However, the anodic oxygen evolution reaction (OER) requires a significant kinetic overpotential, limiting the electrolysis rate. Recently, plasmonic gold nanoparticles (Au NPs) have been introduced to improve charge transfer at the interface between the OER electrocatalysts and the electrolyte under light illumination.

Within the context of polypropylene recycling by dissolution, the potential degradation of polypropylene in solution has been investigated using in situ NIR and Raman spectroscopy. Pure polypropylene, completely free of additives, and commercial polypropylene, low in additives, are degraded on purpose under different conditions. Genetic algorithm combined with partial least squares (GA-PLS) models have been built based on near-infrared (NIR) spectra, and partial least squares (PLS) models based on Raman spectra, to predict the mass average molar mass and the chain-scission rate, respectively, during the degradation process.

Optical responses of twisted bilayer graphene at targeted wavelengths can be amplified by leveraging energy levels of van Hove singularities (VHS) via tuning periods of moiré superlattices. Therefore, precise control of twist angles as well as the moiré superlattices is necessary for fabricating integrated optoelectronic devices such as photodetectors and emitters. Although recent advances in twist angle control help the observation of correlated states in twisted magic-angle graphene structures, the impact of such precise control on enhanced optical absorption is still under investigation.
