Rapid and reliable diagnosis of infectious diseases caused by pathogens, and timely initiation of appropriate treatment are critical determinants to promote optimal clinical outcomes and general public health. Conventional in vitro diagnostics for infectious diseases are time-consuming and require centralized laboratories, experienced personnel and bulky equipment. Recent advances in electroche...

To improve the repair effect of electrochemical chloride extraction, a modified electrode configuration is applied in this investigation. In this configuration, two auxiliary electrodes placed in the anodic and cathodic electrolytes were used as the anode and cathode, respectively. Besides this, the steel in the mortar was grounded to protect it from corrosion. By a comparative experiment, the ...

Porous carbon materials are used for many electrochemical applications due to their outstanding properties. However, research on controlling the pore structure and analyzing the carbon structures is still necessary to achieve enhanced electrochemical properties. In this study, mesoporous carbon nanotube (CNT)-carbon nanofiber electrodes were developed by heat-treatment of electrospun starch wit...

Rapid phenotyping of bacteria to identify drug-resistant strains is an important capability for the treatment and management of infectious disease. At present, the rapid determination of antibiotic susceptibility is hindered by the requirement that, in existing devices, bacteria must be pre-cultured for 2-3 days to reach detectable levels. Here we report a novel electrochemical approach that ac...

The removal of nitroaromatics from polluted water is difficult due to their high stability to conventional treatment methods. This paper presents a method for the destruction of 1,3-dinitrobenzene and 2,4-dinitrotoluene in aqueous solutions. The compounds are shown to be stable to reaction with ozone, even under ultrasonic activation. The use of ultrasound enhances the rate of electrochemical r...

Thin films of orthorhombic V2O5 have been prepared by sol electrophoretic deposition (EPD) followed by post-treatment at 500 ◦C. Their electrochemical and optical performances have been investigated for possible applications in electrochemical/electrochromic devices. Li+-intercalation properties of the films have been explored in two voltage ranges: 0.4 to −1.1 V and 0.4 to −1.6 V versus Ag/Ag+...

Electrochemical post-treatment of ultrathin carbon layer coated cobalt nanoparticles generates a novel electrocatalyst, affording a small overpotential of 333 mV at a current density of 10 mA cm(-2) and a small Tafel slope of ∼58 mV per decade.

Concurrent renewable energy production and wastewater treatment are two main reasons for using microbial fuel cells (MFCs). In this study, real wastewater was used for treating and power generation by air cathode microbial desalination cells (ACMFC). The total duration of voltage generation by ACMFC was about 151.9 ±23.2 h. The maximum voltage produced from municipal wastewater treatment was 27...

Enzymatic and microbial electrochemical systems (MESs) utilize the ability of biological components— enzymes and microbes—to catalyze an oxidation or reduction reaction at solid-state electrodes. A commonly known system is the microbial fuel cell in which electricity is produced via the microbially catalyzed oxidation of organic matter. The electrochemical systems that are discussed have a wide...
