Abstract
The reduction of oil fouling in pipes and tanks is essential for the oil storage and transportation industry. In this study, a superhydrophilic/underwater superoleophobic surface (SUSS) with high wearability, weatherability, and durability was developed using a facile two-step synthesis method and used to expel fouled oil from the surface using water without a surfactant. Some typical oils, including kerosene and white oil, can be spontaneously expelled by static water; however, rapeseed oil requires motive water for expulsion because of its high affinity for the SUSS. Different occurrences can be estimated based on a correlated parameter, φ(Pe), which is calculated using an introduced dimensionless number, P e = σ L V u μ . A positive value of φ indicates the occurrence of fouled-oil expulsion by water replacement, whereas a negative value indicates no occurrence of this phenomenon. This study provides a facile strategy for the rapid cleansing of oil-fouled pipes and tanks without using a detergent, thereby lowering costs and environmental risks.

Abstract
With the advantages offered by cationic photopolymerization (CP) such as broad wavelength activation, tolerance to oxygen, low shrinkage and the possibility of "dark cure", it has attracted extensive attention in photoresist, deep curing and other fields in recent years. The applied photoinitiating systems (PIS) play a crucial role as they can affect the speed and type of the polymerization and properties of the materials formed. In the past few decades, much effort has been invested into developing cationic photoinitiating systems (CPISs) that can be activated at long wavelengths and overcome technical problems and challenges faced. In this article, the latest developments in the long wavelength sensitive CPIS under ultraviolet (UV)/visible light-emitting diodes (LED) lights are reviewed. The objective is, furthermore, to show differences as well as parallels between different PIS and future perspectives.
