Quantitative analysis of microplastics in seawater based on SERS internal standard method.

Microplastics can enter the human body through the food chain and can cause cardiovascular or cerebrovascular diseases; thus, it is essential to detect microplastics sensitively and accurately. Traditional methods have some drawbacks, such as a low sensitivity and complicated experimental procedures, so it is difficult to detect microplastics less than 1 μm. While surface enhanced Raman scattering technology can compensate for these shortcomings, there are fewer reports on the quantitative detection of microplastics using SERS technology.

Squid inspired elastomer marine coating with efficient antifouling strategies: Hydrophilized defensive surface and lower modulus.

In antifouling applications for the marine industry, low surface energy coatings entail turbulent water flow to release marine biofouling, which presents a substantial challenge for antifouling in the static situation. The traditional solution is to add environmentally friendly antifouling agents, but it has the problem of exhaustion. Therefore, the low surface energy elastic antifouling coating without antifoulants has high research value.

The Efficacy of Naikan Therapy on Male Offenders: Changes in Perceived Social Support and Externalized Blame.

Naikan is a contemplative self-observation practice that originated from Japanese Shin Buddhism and is utilized for rehabilitating prison inmates in many countries. Although some investigations have provided initial evidence for its efficiency in decreasing recidivism, there is still a need for further investigation of the effectiveness of Naikan on other outcomes through more controlled studies. The present study aimed to investigate the efficacy of Naikan therapy on male offenders' perceived social support and externalized blame.

Low-loss light transmission in a rectangular-shaped hybrid metal trench at 1550 nm.

A hybrid plasmonic waveguide consisting of a high-index dielectric core embedded inside a rectangular-shaped metallic trench is proposed and its guiding properties are investigated at the wavelength of 1550 nm. Numerical simulations based on the finite element method have demonstrated that the introduced dielectric core could greatly reduce the modal loss of the metal trench while maintaining strong confinement of light. The effects of dielectric core size, material of the cladding and the dielectric core on the modal properties have been systematically investigated.
