The surface-enhanced Raman spectroscopy (SERS) technique is of great importance for insight into the transient reaction intermediates and mechanistic pathways involved in heterogeneously catalyzed chemical reactions under actual reaction conditions, especially in water. Herein, we demonstrate a facile method for in situ synthesis of nanocrystalline magnesium oxide-Ag(0) (nano MgO-Ag(0)) hybrid ...

In this study, polyimide (PI)/Ag nanowire (AgNW) nanocomposite aerogels with extremely high mechanical performance have been fabricated utilizing amine-modified AgNWs as mechanical nanoreinforcement particulates and crosslinking agents. Initially, AgNWs were fabricated and surface modified by p-aminothiophenol (PATP), then the aminated AgNWs were dispersed into polyamide acid solution and aerog...

Nowaday, the construction of new electrochemical biosensors with improved bioanalytical performance and robustness is directly linked to the development of novel strategies for tailormade design of electrode surfaces. Such strategies should provide electrical interfaces with nanoor microsized tree-dimensional topology that allow the successful and stable immobilisation of the biomolecules witho...

Pyromellitic dianhydride 1 was used as starting compound for the synthesis of some new derivatives of condensed dipyrrole, dibenzoxazine, and dipyridazine. Thus, the diimide 2 was formed on fusion of 1 with urea, thiourea and/or thiosemicarbazide. Also, 1 reacted with benzylamine to give terephthalic acid derivative 3 which on fusion afforded the cyclic diimide 4. The reaction of 1 with o-amino...

Aryl-substituted benzothiazoles and benzoxazoles are an important class of heterocyclic compound and have shown a wide range of biological activities, such as antitumor, antiviral, and antimicrobial activities. In addition, these compounds have become essential building blocks for the synthesis of conjugated functional materials, such as industrial dyes and plant growth regulators. The conventi...

This work presents porous zirconia-toughened alumina ceramics functionalized with [email protected]/[email protected] core–shell nanoparticle (NP) for in situ monitoring of catalytic reactions via surface-enhanced Raman scattering (SERS) which is augmented by the open cell foam structure ceramic support. In this respect, enables efficient light trapping and propagation onto coated surface, prov...
