“…Nanoemulsions are composed of two or more incompatible liquids that is a two‐phase liquid system in which the contained phase is generally referred to as the internal or dispersed phase, which exists generally in the form of small droplets, and the contained phase is referred to as the external or continuous phase (Dong et al ., 2019). Nanoemulsions can effectively encapsulate the active substance therein.…”

Antimicrobial photodynamic therapy (aPDT) is an effective method in the field of sterilisation. Singlet oxygen ( 1 O 2 ) is an important substance in photodynamic sterilisation that needs to be detected. It involves energy transfer from an excited photosensitiser to surrounding oxygen molecules to produce cytotoxic 1 O 2 species, a process termed as type II reaction. Traditional photodynamic sterilisation for fresh produce generally involves only a single photosensitiser and uses nanoemulsions coating to make the photosensitiser work better. This allows the emulsion to produce only a limited amount of reactive oxygen species (ROS) in the presence of light, such that the bactericidal effect is limited. We have innovatively compounded two photosensitisers and stored them as nanoemulsions. The composite photosensitiser produces relatively higher ROS and the nanoemulsions have good stability as well as rheological properties, and the photosensitisers are well coated in the emulsions. In summary, nanoemulsions based on composite photosensitisers showed synergistic activity in controlling the growth of Staphylococcus aureus, which provides a novel approach for raw sterilisation to maintain food safety.

The titanium alloy Ti6Al4V ELI (grade 23) is widely used in biomedical industry because of its engineering attributes. However, it requires surface modifications and has processing challenges because it is difficult to machine nature. Therefore, powder-mixed electric discharge machining process is commonly applied to simultaneously machine the material and carry out surface treatment. The performance of the process is limited by both low cutting efficiency and the formation of a rough surface. In this regard, the current study evaluates SiC powder-mixed electric discharge machining of Ti6Al4V ELI using a range of tool materials such as copper, brass, graphite, and aluminum along with a comprehensive list of process parameters. The surface roughness parameters involving arithmetic roughness, the average peak-to-valley distance, and the highest peak-to-deepest valley distance along with material removal rate are comprehensively studied. Taguchi design of experiments L16 orthogonal array is used to study the process performance with parametric effect analysis, parametric significance analysis, and surface morphological analysis with a scanning electron microscope. Furthermore, the experimental results are optimized against a multi-response optimization matrix using grey relational analysis approach. An optimal compromise between surface attributes and cutting efficiency is identified by Al electrode, pulse current of 14 A, pulse on time of 75 µs, pulse off time of 75 µs, and negative polarity parametric conditions.
