We fabricate α-terthiophene single-molecule junctions (SMJs) and characterize their conductive states by the simultaneous measurements of surface-enhanced Raman scattering (SERS) electronic conductance. The SMJ showed broad conductance distribution due to different portions multiple aromatic rings connected electrodes. SERS spectra obtained measurement vibrational energy C−C stretching mode dep...

Factors affecting the performance of polyvinyl chloride based ion selective electrode such as using different cationic exchangers and ionophores as well as sensor fabrication procedures were recently the scope of study by several researchers. This work presents an environment friendly electro-analytical method for the determination of Triprolidine HCl (TRI) and Pseudoephedrine HCl (PSE). A comp...

The goal of information gathering is to obtain data from the environment generating an accurate model for the application of interest. In many applications the information gathering process requires to obtain measurement of the phenomena of interest in harsh or dangerous conditions (e.g., environmental monitoring applications of water in a lake or search and rescue operations in disaster respon...

Doping very small amounts of Ru(II) into a flexible, ultramicroporous, fluorescent Zn(II) coordination polymer produced phosphorescent materials with very high and tunable oxygen quenching efficiency; and a simple color-changing ratiometric oxygen sensor has been constructed.

BACKGROUND The Respiration Activity Monitoring System (RAMOS) is an established device to measure on-line the oxygen transfer rate (OTR), thereby, yielding relevant information about metabolic activities of microorganisms and cells during shake flask fermentations. For very fast-growing microbes, however, the RAMOS technique provides too few data points for the OTR. Thus, this current study pre...

A rapid and simple sequential potentiometric method is described for the determination of nitrate and chloride ions in vegetables, by using home-made ion selective electrodes. The extraction of both ions from the vegetable samples was effected by magnetic stirring of the samples during 30 min in water at room temperature. Direct Potentiometry was used as analytical technique for measurement. Th...
