A new method for extraction and analysis of ethanol and methanol in human whole blood, urine and saliva samples based on headspace solid phase microextraction (SPME) using silver sulfide (Ag(2)S) and polyvinyl chloride (PVC) coated on silver wire is described. Unlike commercial fibers, which are coated on fused silica, the proposed fiber has a metallic base to which the coating adheres very str...

In this work, zeolite NaY was prepared by hydrothermal method. Then, silver ions were replaced in the zeolite NaY with silver nitrate (AgNO3) solution via using ion exchange (IE) method. The Manganese dioxide (MnO2) nanoparticles (9.3 and 15.8 wt %) for guest were deposited in the zeolite AgY(host) structure with Mn(NO3)2 aqueous and KMnO4 solutions by confined space synthesis (CSS) metho...

In this paper, we report direct patterning of metal nanostructures using an embossed solid electrochemical stamp. Microforming of solid superionic stamps using Si templates--analogous to polymer patterning in nano-imprint lithography--is explored. Silver sulfide (Ag₂S)--a superionic conductor with excellent microforming properties--is investigated as a candidate material. Important parameters o...

Introduction A number of works on cationic sensors have been reported in literatures [1] but less attention has been given towards the development of anionic sensors though there is a need for analysis of varieties of anions in different environmental, biomedical, industrial as well as chemical samples[2-3]. Anion sensors are simple, low cost, convenient, portable and provide quick response tow...

The synthesis, properties and reactivity of group 11 organotin sulfide clusters [(R(1)Sn)4(SnCl)2(MPPh3)2S8] (M = Cu, Ag), [(R(3)Sn)10Ag10S20], and [(R(1,3)Sn)2(AuPPh3)2S4] with covalently bound, carbonyl or hydrazine-terminated ligands R(1) = CMe2CH2C(Me)O or R(3) = CMe2CH2C(Me)NNH2 are reported.

The reaction of silver platings to atmospheric sulfur has been documented for several decades, but the fundamentals as to its initiation are still poorly understood. This is aggravated by the general inconsistency observed when exposing silver platings to accelerated test conditions and the relatively long incubation period before issues are observed (12 to 48 months). Speculation has also been...
