    Abstract The world is facing, while writing this review, a global pandemic due to one of the types of the coronaviruses (i.e., COVID-19), which is a new virus. Among the most important reasons for the transmission of infection between humans is the presence of this virus active on the surfaces and materials. Here, we addressed important questions such as do coronaviruses remain active on the inanimate surfaces? Do the types of inanimate surfaces affect the activity of coronaviruses? What are the most suitable ingredients that used to inactivate viruses? This review article addressed many of the works that were done in the previous periods on the survival of many viruses from the coronaviruses family on various surfaces such as steel, glass, plastic, Teflon, ceramic tiles, silicon rubber and stainless steel copper alloys, Al surface, sterile sponges, surgical gloves and sterile latex. The impacts of environmental conditions such as temperature and humidity were presented and discussed. The most important active ingredients that can deactivate viruses on the surfaces were reported here. We hope that these active ingredients will have the same effect on COVID-19.

    Abstract Hydrogen production technologies are attracting widespread interest in energy technologies. The conventional methods for hydrogen production suffer from high cost, restricting their production everywhere. Here, we use waste formation water from a petroleum field and carbon steel materials to produce hydrogen. The most suitable conditions have been investigated to maximize the hydrogen yield. In addition, an ionic liquid (i.e., tributylmethylammonium methyl carbonate, BMAMC) has been used to control the hydrogen generation reaction. We reveal that the amount of hydrogen release rapidly increases with decreasing pH of the solution from 6.7 to 2.5. A further increase in temperature resulted in more amount of hydrogen release. Our study investigates the influence of chloride ions on hydrogen generation activity. The results revealed that ionic liquid BMAMC remarkably decreases the amount of hydrogen release with an efficiency of 92% at 5.08 × 10

    Abstract We present a promising method for producing pure hydrogen energy from the dissolution of zinc metal in waste oilfield water (WOW) under various conditions. This process mainly consumes zinc metal and WOW. The results show robust dependence on the temperature and solution pH of the hydrogen gas output. Low pH (2.5) and high temperature (338 K) were discovered to be the better conditions for hydrogen production. The 1-ethyl-3-methylpyridinium ethyl sulfate (EMP-ES) ionic liquid is used to regulate the rate of hydrogen generation for the first time. It has been confirmed that the rate of the dissolution of zinc increased faster and produced more hydrogen per unit of time by an increase in solution temperature and a decrease in solution pH. The adsorption of EMP-ES on the active sites of the Zn surface is unrestrained with mixing physical and chemical orientations. SEM, EDX, and FTIR spectroscopy inspections have been utilized to identify and characterize surface corrosion of zinc in WOW. Furthermore, this process is completely secure and can generate energy on demand.

    Abstract In this review, the importance of corrosion inhibitors in desalination plants is briefly discussed, with an emphasis on the various types for effective corrosion control techniques. The review highlighted the most significant corrosion inhibitors used in desalination plants for minimizing the corrosiveness of the source water throughout pretreatment, reverse osmosis, and post-treatment stages. Water composition, temperature and pressure, pH, dissolved oxygen, flow velocity, chloride content, fouling, and scaling are all described as factors affecting corrosion in desalinated water. The types of corrosion inhibitors used in desalination plants are summarized, including inorganic inhibitors, organic inhibitors, and eco-friendly inhibitors. Environmental issues and long-term inhibition are highlighted briefly.

    Abstract Introduction: The textile, paper, rubber, plastic, leather, cosmetics, pharmaceutical, and food sectors extensively use malachite green (MG). In spite of this, it has mutagenic, carcinogenic, teratogenic, and, in some circumstances causes chronic respiratory disease.
    Objectives: In this work, we used sodium alginate, Sargassum latifolium aqueous extract, and their silver nanoparticles to test their potential as inexpensive adsorbent agents to remove malachite green dye from aqueous solutions.
    Methods: The removal rate of MG was determined using a series of bioadsorption experiments. Besides, the effect of different factors on bioadsorption, such as pH, adsorbent dose, contact time (min), and different concentrations of MG dye was investigated.
    Results: The removal efficiency of MG dye by alginate nanoparticles, alginate, Sargassum latifolium aqueous extract, and S. latifolium aqueous extract nanoparticles was 91, 82, 84, and 68 respectively. The optimal conditions for bioadsorption of malachite green dye were pH 7, a contact time of 180 min, and an adsorbent dose of 0.02 g. The adsorption isotherm was fitted to Langmuir and Freundlich isotherm. Also, UV and FT-IR before and after the bioadsorption of MG were performed to confirm the bioadsorption process.
    Conclusion: Our results indicated that alginate nanoparticles were the most effective bioadsorbent agent.
