The use of hydrogen as fuel presents many safety challenges due to its flammability and explosive nature, combined with its lack of color, taste, and odor. The purpose of this paper is to present an electrochemical sensor that can achieve rapid and accurate detection of hydrogen leakage. This paper presents both the component elements of the sensor, like sensing material, sensing element, and signal conditioning, as well as the electronic protection and signaling module of the critical concentrations of H.

Article Synopsis
  • * The yeast strains demonstrated significant removal efficiencies, achieving up to 97% for nitrate and 96% for lead in synthetic wastewater, while also boosting biomass growth.
  • * The presence of a crude biosurfactant enhanced contaminant removal rates even further, suggesting effective practical applications for cleaning wastewater and recovering valuable metals at a low cost.

Article Synopsis
  • Nutrient and organic pollution threaten aquatic ecosystems by increasing organic carbon, reducing light penetration, and harming submerged vegetation.
  • The study focuses on the ability of bacterial strains Pseudomonas aeruginosa and Chryseobacterium sp. to create biofilms for filtering out pollutants from municipal wastewater.
  • Results indicate significant reductions in nutrient pollution (up to 91% for nitrite and 71% for phosphate) and lower chemical oxygen demand (COD) without additional aeration, highlighting potential cost-effective wastewater treatment solutions.
