Article Synopsis
  • The research investigates how oxidation heat treatment (OHT) and dual opaquing techniques affect the bond strength between metal and ceramic in dental materials.
  • Eighty samples were created, divided into two main groups based on oxidation treatment, and further categorized by single or double layers of opaque porcelain, followed by flexural strength testing.
  • Results showed that the combination of OHT and double layering (group A2) resulted in the highest bond strength, highlighting the significance of these techniques in enhancing ceramo-metal restorations.

Accurately estimating Battery State of Charge (SOC) is essential for safe and optimal electric vehicle operation. This paper presents a comparative assessment of multiple machine learning regression algorithms including Support Vector Machine, Neural Network, Ensemble Method, and Gaussian Process Regression for modelling the complex relationship between real-time driving data and battery SOC. The models are trained and tested on extensive field data collected from diverse drivers across varying conditions.

In early years, SERS-active substrates were generally noble metals. However, their practical applications were limited due to their poor biocompatibility, low uniformity and high cost. Recently, the utilization of semiconductor SERS-active substrates has greatly expanded the applications of SERS in many fields.

Article Synopsis
  • The article describes a simple method to create silver nanoparticles (Ag NPs) embedded in a graphene oxide and cross-linked polyvinyl alcohol (PVA) matrix, which is treated with gamma radiation.
  • It was found that the thermal conductivity ('k') of the samples first decreases with radiation doses up to 5 kGy and then increases at higher doses, indicating that gamma irradiation affects the material's structural properties.
  • The PVA/GO-Ag/GA composite exhibits low thermal conductivity and strong electrical insulation, making it suitable for applications in thermal management, such as thermal insulation for microsensors and wire insulation in nuclear reactors.
