Calcium carbonate sediment corrosion and formation investigation in drinking water distribution network in Sough City, Iran.

One of the major problems facing the water industry is corrosion and sedimentation, which causes problems such as reduced water quality and the useful life of water supply network equipment. This study aimed to investigate the corrosion and sediments formed in the drinking water distribution network of Sough City. In this cross-sectional study, samples were prepared from 7 wells, water storage reservoirs, and a dedicated water supply network in this area from 2006 to 2017.

Determination of bupropion by off-line coupling FeO@CuO&GO nanocomposite and ion mobility spectrometry with application to biological samples.

In this study, an off-line coupling of dispersive solid-phase extraction (DSPE) and ion mobility spectrometry (IMS) was introduced to extract and determine bupropion (BUP). A magnetic nanocomposite adsorbent (FeO@CuO&GO) was fabricated by combining graphene oxide (GO) sheets with FeO and CuO through coprecipitation method. The synthesized adsorbent was characterized and analyzed using the analytical techniques.

Fabrication of a novel sensor based on Cu quantum dot and SH-SiO nanoparticles supported on copper-based metal organic framework (Cu QD-SH-SiO@Cu-MOF) and its application for the simultaneous determination of norepinephrine, piroxicam and epinephrine.

In this research, a novel electrochemical sensor with excellent sensitivity was fabricated based on Cu quantum dot (Cu QD) and SH-SiO nanoparticles immobilized on copper-metal-organic frameworks (Cu-MOFs) for determining piroxicam and simultaneous determination of norepinephrine, piroxicam and epinephrine. The nanoparticles were synthesized and characterized using FT-IR, EDX, FESEM, TEM and BET, and were subsequently used to modify carbon paste electrode. Cu QD-SH-SiO@Cu-MOF for electrode modification possesses a distinctive structure and a high conductivity that raises the electron transfer rate and enhances the performance of electrochemical sensors.

A review on analytical methods with special reference to electroanalytical methods for the determination of some anticancer drugs in pharmaceutical and biological samples.

It is widely accepted that cancer, the second leading cause of death, is a morbidity with big impacts on the global health. In the last few years, chemo-therapeutic treatment continually induces alone most lengthy consequents, which is extremely harmful for the physiological and psychological health of the patients. In the present research, we discuss the recent techniques for employed for extraction, and quantitative determination of such compounds in pharmaceutical, and biological specimens.
