Enhanced Biodegradation of Battery-Contaminated Soil Using Bacillus sp. (MZ959824) and Its Phytotoxicity Study

One of the main sources of dangerous chemicals that are dumped untreated into land and water bodies and have a negative influence on the ecosystem are industrial effluents. Seaweeds are currently used for treating industrial effluent effectively. The technology is at a maturing stage. This paper reviews the characterization and cultivation of seaweeds for wastewater treatment. In this present study, different extracts of four seaweeds such as Gracilaria edulis, Sargassum wightii, Turbinaria ornata, and Kappaphycus alvarezii, from the Mandapam coastal regions were analyzed. The seaweeds are used to treat the leather industry effluents collected from EKM leather processing company, Erode, Tamil Nadu, India. Among all, extracts of Gracilaria edulis survived at different concentrations of TDS: 15,000, 25000, and 35000 mg/l. Out of these different ranges, TDS of about 25000 mg/l seaweed named Gracilaria edulis reduced more amounts of chemicals present in the effluent like TDS (93.90%), phosphates (72.71%), nitrate (75.08%), nitrite (76.92%), and turbidity (99.01%) content. Additionally, we produce the quality and strength of agar gel from the cultivation of Gracilaria edulis by the Nikansui method. Finally, we got the extraction procedure to obtain a higher yield of about 10.26% and a maximum gel strength of 92.06 g·cm−2 while maintaining the melting point at 78°C.

<p>In the presence of nitrogen oxides, nitrate-reducing bacteria (NRB) may use nitrate as an electron acceptor, reduce nitrate to nitrite, and finally convert nitrite to nitrogen or ammonium (NO and N2O). Studies have shown that BCX (Bio-Competitive Exclusion) is a viable , ecologically benign, and low-cost technique for regulating NRB in its first phases of study and application. More precisely, Pseudomonas sp. to isolate nitrate-reducing bacteria from oil-field wastewater using 16S rDNA sequencing and selection (NRB). Including NO3 and NO2 as bio-activators has helped researchers get a deeper understanding of the processes that govern NRB activation. The potential for molybdate and NRB to inhibit Sulfate-Reducing Bacteria (SRB) was also investigated. The results showed that NO2 was more effective than NO3. The effect was greatest at a 1:4 ratio of NO3 to NO2. NRB activation synergized with low molybdic acid solution concentrations (5%). Static corrosion model experiments demonstrated the importance of SRB in the corroding process. Biological inhibitors were shown to have the lowest corrosion rates, proving their effectiveness. Scanning electron microscopy was used to examine the corroded steel sheet's surface morphology. In addition, there was almost no surface corrosion or pitting on the steel sheet.</p>

“…Micrometer-sized graphene-based antennas are projected to transmit terahertz-frequency electromagnetic waves [24]. Nano-dipole and patch antenna with the size of several hundred nanometers would be capable of transmitting electromagnetic waves in the terahertz region [25,26]. In general, to match the antenna requirements of 5G mobile communication, the antenna's resonance frequency is set at 3.5 GHz.…”

Carbon nanomaterials have attracted significant consideration and concern due to the unique chemical and physical properties. Recently, nanodiamonds, graphene, and carbon nanotubes are served as electrodes, hydrogen storage elements, and composite materials. In this work, a 5 GHz graphene nanoantenna that falls inside the very-small-aperture terminal (VSAT) C-band range has been fabricated. A graphene substrate with a thickness of h = 0.5 cm is formed which is then used for fabricating a graphene nanoantenna working at 5 GHz. To design and simulate the antenna, Analysis System (ANSYS) electromagnetic desktop software was used. Using the designed graphene antenna, the parameters such as voltage standing wave ratio, three-dimensional radiation pattern, and directivity were obtained. After designing of the antenna using ANSYS software, it was physically fabricated. The graphene was used as a dielectric, copper sheet acted as a patch over as well as ground. Finally, the design was testedusing Vector Network Analyzer (Model: N9925A) and the transmission range was found as 5 GHz.
