Paracetamol that is known as acetaminophen have the most consume as an analgesic and antipyreticdrug in the world. That is formulated in single compound or mixture at many forms such astablets, syrups, suspensions and drops. The last form is intravenous injections. Paracetamol derivedfrom 4-minophenol which is synthesized by acylated the P-acetaminophenol and acetic anhydride.4-aminophenol is t...

Rapid separation and determination of acetaminophen and its hydrolysate with end-channel electrochemical (EC) detection integrated on a plastified poly(ethylene terephthalate) (PET)-toner microchip capillary electrophoresis (CE) system was investigated. In this separation and detection system, a Pt ultramicroelectrode integrated on a three-dimensional adjustor was used as working electrode. Fac...

This article aims to present concepts related to the development of interactive three-dimensional environments using X3D, for local and remote access, enabling integration with real devices that offer a realistic visualization through the stereoscopy. As a case study will be showed how this was applied in the assembly of a classroom at the Federal University of Paraíba.

The catalytic reduction of 4-nitrophenol is considerable importance to a multitude applications and industries. present work introduces new catalyst (AuNP/GNP/MgAl-LDH) containing gold nanoparticles (AuNP) supported on graphene nanoplatelets (GNP) intercalated in Mg Al layered double hydroxides (MgAl-LDH) for the 4-aminophenol using NaBH4 as reducing agent. was characterised by FTIR, XRD, STEM,...
