Unlabelled: We present 2 cases of localized calcification on the anterior surface/subsurface of hydrophilic acrylic intraocular lenses (IOLs) following procedures involving intracameral injection of air. Although this phenomenon has been reported in hydrophilic acrylic IOLs, to our knowledge it has not been reported in the IOLs described in our cases, one a sulcus-fixated supplementary IOL and the other a hydrophilic acrylic IOL with a hydrophobic surface. Centralized opacity of the IOLs was first noted months after Descemet membrane endothelial keratoplasty had been performed in both cases; explantation was required. Laboratory analysis of the IOLs confirmed calcification of the anterior surfaces in a localized pattern in the area of the capsulorhexis or pupil.

(Meth)acrylate polymers are commonly used as photoresist materials in photolithography. However, these polymers encounter the problem of swelling during the development process. To address this, we explored the use of a hydrophobic group to control the solubility in the hydrophilic developer.

Background: Hydrophilic monomer 2-hydroxyethyl methacrylate (HEMA)-free adhesive systems are gaining increasing popularity nowadays. Although the addition of HEMA to dental adhesives improves dentin wettability and resin diffusion into demineralized collagen fibrils, HEMA's high hydrophilicity can lead to hydrolytic degradation of the adhesive interface. Thus, HEMA-free adhesive systems have been developed.

For the purpose of efficient temporary plugging and self-removal of the plugging of reservoir formations, the thermally induced expandable and acid-generating temporary plugging agent (TAPA) was prepared with acrylonitrile (AN), methacrylic acid (MAA), ,-dimethylacrylamide (DMAA), and butyl acrylate (BA) as the shell monomers as well as the carboxylate esters with high boiling points as the core material. The TAPA was structurally characterized, and the properties were studied. The results showed that the TAPA had a good spherical structure with a median particle size (D50) of 16.

Background: Hot-melt Pressure-sensitive Adhesives (HMPSA) are eco-friendly pressuresensitive adhesives, with the potential of being used as substrates for transdermal patches. However, due to the low hydrophilicity of HMPSA, the application is limited in the field of Traditional Chinese Medicine (TCM) plasters.
Methods: Three modified HMPSA were prepared with acrylic resin EPO, acrylic resin RL100, and Polyvinylpyrrolidone (PVP) as the modifying materials.

Hybrid polyionic complexes (HPICs) are colloidal structures with a charged core rich in metal ions and a neutral hydrophilic corona. Their properties, whether as reservoirs or catalysts, depend on the accessibility and environment of the metal ions. This study demonstrates that modifying the coordination sphere of these ions can tune the properties of HPICs by altering the composition of the complexing block or varying formulation conditions.
