Background And Objective: To describe early clinical results with the porous polyethylene smooth surface tunnel (SST) enucleation implant.
Patients And Methods: Uncontrolled, prospective interventional case series of patients undergoing enucleation with placement of the SST implant. This implant consists of a porous polyethylene sphere with a smooth anterior surface containing pre-drilled tunnels to facilitate direct suturing of the rectus muscles to the implant without use of an implant wrap. Postoperatively, socket healing was assessed, and prosthesis and socket motility were evaluated by the surgeon using an ordinal scale (0 = no motility to 4 = excellent motility).
Results: Thirty patients received the SST implant, with a mean follow-up of more than 23 months. Two cases of exposure occurred and were managed surgically without the need for explantation. Mean socket motility was 3.1 on a 0 to 4 ordinal scale, with mean prosthesis motility of 2.8.
Conclusion: The SST implant provides satisfactory socket motility and is generally well tolerated in the anophthalmic socket without the need for wrapping material.

There are two major styles of maggot debridement dressings: (1) confinement dressings that form a cage around the wound, and (2) containment dressings that completely surround the maggots within a sealed porous bag. For producers and clinicians wanting to prepare containment dressings using readily available polyester bags, it is currently difficult to seal these bags without expensive high-temperature plastic welders. This study aimed to identify simple and affordable methods for sealing maggots within polyester net bags.

In recent years, the accumulation of waste plastics and emergence plastic-derived pollutants such as microplastics have driven significantly the development and updating of waste plastic utilization technology. This study prepared the porous carbon (PC-1-KOH) material directly from polyethylene terephthalate (PET) in waste plastic bottles using KOH activation and molten salt strategy for efficient removal of antibiotic tetracycline (TC). The maximum removal efficiency of TC was 100.

Clay minerals show significant potential as fillers in polymer composite solid electrolytes (CSEs), whereas the influence of their microstructures on lithium-ion (Li) transport properties remains insufficiently understood. Herein, we design advanced poly(ethylene oxide) (PEO)-based CSEs incorporating clay minerals with diverse microstructures including 1D halloysite nanotubes, 2D Laponite (Lap) nanosheets, and 3D porous diatomite. These minerals form distinct Li transport pathways at the clay-PEO interfaces due to their varied structural configurations.

Poly(ethylene oxide) (PEO)-based solid-state polymer electrolyte (SPE) is a promising candidate for the next generation of safer lithium-metal batteries. However, the serious side reaction between PEO and lithium metal and the uneven deposition of lithium ions lead to the growth of lithium dendrites and the rapid decline of battery cycle life. Building a LiF-rich solid electrolyte interface (SEI) layer is considered to be an effective means to solve the above problems.
