  • Publication number: 20250216376
    Abstract: Proposed is a method of analyzing microplastic particles in a water system. The method includes providing raw water containing microplastic particles, freezing and thawing the raw water at least once to generate microplastic aggregates in the raw water, recovering the microplastic aggregates, and analyzing the recovered microplastic aggregates. According to the method, the microplastic particles are precipitated in the water system without the use of an additional coagulant, whereby the effect of coagulants on the subsequently recovered microplastic aggregates may be ruled out. In addition, the process configuration is simple because the aggregates can be separated from the supernatant without using any additional treatment process.

  • Patent number: 12342879
    Abstract: Improved personal protective equipment facial wear including, in one embodiment, an at least partly adhesive mask, and one or more adhesive eye shields. In one implementation, the mask avoids significant contact with the delicate periorbital skin of the wearer, yet provides a substantially airtight seal so as to preclude moisture vapor transfer and “fogging” of eyeware or instruments. In another implementation, adherence of the eye shield is at least partially overlapping with the mask and creates an at least partial seal around a perimeter of the eye shield. Further, an at least partial seal is formed around a perimeter of the mask. The mask and eye shield additionally prevent nasal air flow obstruction, and address the problem of skin irritation and attachment during normal facial expression and movement of the wearer.
