In this paper we unveil a new sensing strategy for sensitive and selective detection of Hg2+ through surface-enhanced Raman scattering (SERS) using Ag2Te nanoparticles (NPs) as a substrate and recognition element and rhodamine 6G (R6G) as a reporter.Ag2Te NPs prepared from tellurium dioxide and silver nitrate and hydrazine in aqueous solution conta

Calcium hydroxide (CH) is widely used as an intracanal medicament between appointments to increase the number of canals free from bacteria.However, the remnant CH hinders the penetration of disinfectants and sealers into dentinal tubules and compromises the seal of the canal filling.Therefore, residual CH must be removed before permanent root canal
Ambient noise is a subtle form of pollution in large urban areas, degrading human health and well-being.In Europe, directives require that urban environmental noise be measured and mapped for the main periods of the daily cycle.Subsequent analyses of human exposure to noise A Vitamins in those periods is usually conducted using resident (i.e., nigh
