Evaluation and Assessment of the Colour Stability of Modified Polymethyl Methacrylate Denture Base Materials and Polyether Ether Ketone in a Cast Partial Denture Framework: An In-Vitro Study.

Background One of the frequent aesthetic issues patients confront is the loss of colour and lifeless appearance of the dentures of the base materials of their dentures after regular use. This leads to a lack of motivation to use the denture regularly. Due to the drawbacks of conventional PMMA, polyether ether ketone (PEEK) and newer polymethyl methacrylate (PMMA)-based materials have now started being used in cast partial denture frameworks due to their superior physical and biological properties.

Interdigitated electrodes-based Au-MoShybrid gas sensor for sensing toxic CO and NHgases at room temperature.

In the quest to create effective sensors that operate at room temperature, consume less power and maintain their stability over time for detecting toxic gases in the environment, molybdenum disulfide (MoS) and MoS-based hybrids have emerged as potent materials. In this context, the current work describes the fabrication of Au-MoShybrid gas sensor fabricated on gold interdigitated electrodes (GIEs) for sensing harmful CO and NHgases at room temperature. The GIEs-based Au-MoShybrid sensors are fabricated by decorating MoSnanoflowers (MNF) with varying size of Au nanoparticles using an inert gas evaporation technique.
