A hybrid coating made of poly (methyl methacrylate) with SiO2-TiO2 particles (PMMA/SiO2-TiO2) has been developed for use as a coating on nanosatellites, evaluating its resistance to high vacuum by quantifying its weight loss. The coating was applied on an Al 7075 aluminum substrate used for the aerospace sector. PMMA/SiO2-TiO2 hybrid coatings were prepared using sol-gel reaction in situ assisted with sonochemistry.

Article Synopsis
- A clinical trial tested the effectiveness of adding nanogold particles to denture bases made of polymethyl methacrylate (PMMA) against standard acrylic bases, focusing on their impact on bacterial growth.
- Twenty-two male patients with no teeth received either traditional acrylic dentures or those enhanced with nanogold, and microbial growth was measured over time around the implants.
- Results showed that dentures with nanogold significantly reduced bacteria counts (Candida albicans, Escherichia coli, and Streptococcus mutans) at 2, 4, and 6 months compared to traditional dentures, suggesting a promising improvement in oral hygiene.

Detecting glucose levels is crucial for diabetes patients as it enables timely and effective management, preventing complications and promoting overall health. In this endeavor, we have designed a novel, affordable point-of-care diagnostic device utilizing microfluidic principles, a smartphone camera, and established laboratory colorimetric methods for accurate glucose estimation. Our proposed microfluidic device comprises layers of adhesive poly-vinyl films stacked on a poly methyl methacrylate (PMMA) base sheet, with micro-channel contours precision-cut using a cutting printer.

Article Synopsis
- PMMA resins, commonly used in medical and dental fields, are vulnerable to bacterial biofilm formation, which can lead to material degradation and increased infection risk.
- In a study, the effects of Pseudomonas aeruginosa and Staphylococcus aureus biofilms on PMMA surfaces were examined over a 45-day incubation period, focusing on factors like biofilm adhesion, surface roughness, and hydrophobicity.
- Results showed that biofilm exposure significantly altered PMMA surface properties, including increased roughness and hydrophobicity, suggesting a need for strategies to mitigate biofilm formation on these materials.
Bond strength of 4META-MMA-TBB resin to a CAD/CAM composite resin block and analysis of acetone-insoluble cured resin residues at adhesive interfaces.

This study investigated the adhesion of 4META-MMA-TBB resin to CAD/CAM composite resin blocks. CAD/CAM composite resin blocks were subjected to alumina blasting, ceramic primer treatment, or both, and then bonded with 4META-MMA-TBB resin. The tensile bond strength of 4META-MMA-TBB resin to blocks without surface treatment was approximately 20 MPa, but with surface treatment, it significantly improved to approximately 40 MPa.
