Abstract Previous studies using gram-positive and -negative bacteria demonstrated that hydrolysis of silicon nitride (Si3N4) in aqueous suspensions elutes nitrogen and produces gaseous ammonia while buffering pH. According to immunochemistry assays, fluorescence imaging, and in situ Raman spectroscopy, we demonstrate here that the antipathogenic surface chemistry of Si3N4 can be extended to polymethylmethacrylate (PMMA) by compounding it with a minor fraction (∼8 vol.%) of Si3N4 particles withou...

Abstract 3D printing is nowadays a consolidated standard for the manufacturing of various polymeric materials. Stereography, in particular, has seen an ever-growing industrial interest due to the high precision and the flexibility. Methacrylated resins are a common, inexpensive choice for high resolution additive manufacturing, but their mechanical properties are strongly influenced by oxidation and thermal cycling. In this work, samples produced with a commercially available methacrylated resin...

Abstract Most structural bioceramics are comprised of metallic oxides such as alumina and zirconia. They are generally considered to be completely bioinert, but a non-oxide ceramic, silicon nitride, achieves equivalent levels of mechanical reliability while being bioactive. Silicon nitride can not only stimulate cellular proliferation but it is also antipathogenic with demonstrated efficacy against Gram-positive and Gram-negative bacteria, fungi, and viruses. In this work, three physical vapor d...

Surface inactivation of human microbial pathogens has a long history. The Smith Papyrus (2600 ~ 2200 B.C.) described the use of copper surfaces to sterilize chest wounds and drinking water. Brass and bronze on doorknobs can discourage microbial spread in hospitals, and metal-base surface coatings are used in hygiene-sensitive environments, both as inactivators and modulators of cellular immunity. A limitation of these approaches is that the reactive oxygen radicals (ROS) generated at metal surfa...

Abstract Rice husk ash (RHA), a by-product of a biomass combustion plant, was investigated as a new humidity sensing material. The raw material was first calcined at 500 °C for 3 h and then characterized by X-ray diffraction (XRD), N2 adsorption, laser granulometry and field emission-scanning electron microscopy (FE-SEM). Thick-film sensors were fabricated by screen-printing technique onto α-alumina substrates with Pt interdigitated electrodes and fired at 600 °C. The sensors were characterized ...

Surface roughness, bioactivity, and antibacterial properties are desirable in skeletal implants. We hot-pressed a mix of particulate sodium chloride (NaCl) salt and silicon nitride (β-Si3N4) onto the surface of bulk PEEK. NaCl grains were removed by leaching in water, resulting in a porous PEEK surface embedded with ~15 vol.% β-Si3N4 particles. This functionalized surface showed the osteogenic and antibacterial properties previously reported in bulk silicon nitride implants. Surface enhancement ...
