“…To keep the rate of temperature in a higher range and decrease the energy loss, scientists have applied nano-thermal insulators that are more economical (Afra et al 2021;Zhao et al 2021;Zhou et al 2020). Gas and oil products can be cleaned from H 2 S by applying nanomaterials (Agarwal and Sudharsan 2021). Utilizing starch nano coatings (Wang et al 2021), Lignin and nano-silica (Gong et al 2021), Lotus leaf coated with nano-SiO 2 (Yang et al 2021), and nano zeolite membrane are new methods for the separation of oil and water due to their high hydrophobic property (Anis et al 2021).…”

Nanotechnology is one of the most emerging fields of research within recent decades and is based upon the exploitation of nano-sized materials (e.g., nanoparticles, nanotubes, nanomembranes, nanowires, nanofibers and so on) in various operational fields. Nanomaterials have multiple advantages, including high stability, target selectivity, and plasticity. Diverse biotic (e.g., Capsid of viruses and algae) and abiotic (e.g., Carbon, silver, gold and etc.) materials can be utilized in the synthesis process of nanomaterials. "Nanobiotechnology" is the combination of nanotechnology and biotechnology disciplines. Nano-based approaches are developed to improve the traditional biotechnological methods and overcome their limitations, such as the side effects caused by conventional therapies. Several studies have reported that nanobiotechnology has remarkably enhanced the efficiency of various techniques, including drug delivery, water and soil remediation, and enzymatic processes. In this review, techniques that benefit the most from nano-biotechnological approaches, are categorized into four major fields: medical, industrial, agricultural, and environmental.

One of the most serious safety and health concerns during drilling oil and gas wells is the potential release of hydrogen sulfide (H 2 S) to the surface, exposing workers to high risks. Serious corrosion-related damage to handling equipment is also inevitable in the presence of H 2 S. Various H 2 S scavengers have been utilized, but each has its pros and cons; hence, research is continuing to develop an optimum and feasible scavenger. Since manganese monoxide (MnO) is a reactive metal oxide with high oxidation and absorption capabilities, it may have the potential to effectively scavenge H 2 S during drilling operations when included in drilling mud formulations. Consequently, the key aim of this work is to investigate the H 2 S scavenging performance of the aqueous drilling fluid containing MnO. This work studied the impact of MnO addition on the drilling mud’s alkalinity, rheological behavior, filtration performance, and corrosion tendency. The experiments were also conducted for mud without a scavenger and a fluid containing the SourScav commercial scavenger, which serves as a benchmarking reference. The findings demonstrated that MnO performed exceptionally well for H 2 S scavenging where it boosted the aqueous mud’s scavenging capacity from 84.3 to 426.2 mg of H 2 S/L of mud, showing more than 400% improvement relative to the base mud. Additionally, this scavenging performance is about 2.1 times higher than that of the commercial scavenger. As opposed to SourScav, MnO maintained the mud’s pH at a safe level above 10. The addition of either MnO or SourScav did not weaken the mud rheology and provided practically satisfactory rheological parameters. Both SourScav and MnO marginally increased the formed filter-cake thickness from 2.9 to 3.9 mm with a slight increment in the filtrated volume but still within the acceptable limits. The corrosion test indicated the noncorrosive characteristics (i.e., the corrosion rate was nearly zero) of MnO and the commercial scavenger. This study illustrates the promising utilization of MnO as a cost-effective H 2 S scavenger, enhancing the efficiency and safety of drilling operations.
