“…The global spread of the coronavirus disease caused by new SARS-CoV-2 variants resulting in the severe acute respiratory syndrome remains a major health concern, leading to increased patient mortality and its identification is required as soon as the samples are identified as "positive" [16,17]. The use of graphene oxide demonstrated efficient adsorption of 18F-FDG, providing a promising alternative method for decontamination of surfaces contaminated with radioactive material [18].…”

Spreading infectious illnesses such as viral meningitis, hepatitis, and cytomegalovirus among people is facilitated by spitting in public. India is more prone to transferring infectious illnesses. Recent research discovered that the new Coronavirus may also be transmitted via an infected person’s saliva. Self-collected saliva from 91.7% of patients contains COVID-19. Numerous nations have prioritized preventing individuals from spitting in open or public areas such as hospitals, parks, airports, train stations, etc. The UVC range has a greater damaging effect on microbial cells because microorganisms’ intracellular components, such as RNA, DNA, and proteins, are sensitive to UVC photon absorption. In this article, the design and construction of a solar-concentrating spittoon is attempted. At its receiver, it can create a temperature of 390 K and 176 W of heat. At this temperature, most viruses (including Coronavirus), bacteria, and pathogens are inactivated. Daily, from 8:00 a.m. until 5:00 p.m., the solar-concentrating spittoon is functional. The solar-concentrating spittoon performance was best for nine hours. The receiver thermal efficiency was 80% and 20% of heat was lost to the surroundings. The overall efficiency was found to be 70%. During this time, most people spend their time outside, where this solar-powered spittoon can incinerate human cough and spit within one minute. The installation of this solar-concentrated spittoon will aid in preventing the spread of fatal dangerous diseases and cleaning the city.

Radioactive wastes by products excreted from radioiodine (RAI) therapy patient waste such as urine, faeces, sweat and puke might risk to radiation contamination if not systematically manage. These wastes can affect human health and environment, thus sustain and systematic management must be strictly considered. In addition, radiopharmaceutical preparations in nuclear medicine risk to radioactive spillage by chances. In this study, new sustainable adsorption technique by using agriculture product was proposed to decontaminate the possibilities of radioactive spillage in RAI therapy where different concentrations of bamboo activated carbon (BAC) was mixed with pure 131I and filtered by using filter paper. Radioactivity for each filtered sample (sediment) was measured using dose calibrator to determine kinetic reactions of adsorbed radioactive substances. The data shows the sediment radioactivity was increased with increased of BAC concentrations. The radioactivity loss after filtration was 76.1% (50 mg/ml), 76.3% (100 mg/ml), 83.5% (150 mg/ml), 80.4% (200 mg/ml), 85% (250 mg/ml) and 68% (control) due to high agglomeration between BAC and 131I. Mixtures with highest BAC concentration was then characterized using FESEM and EDX for morphology and elemental analysis. FESEM image proved there were porous structures on the BAC to attract 131I and other molecules. EDX revealed that 131I and other elements were attracted to BAC layered sheets. This study revealed that BAC performed different capabilities as an adsorbent material under different experimental conditions and has high potential for sustainable radionuclide decontamination agents especially for RAI therapy in ensuring continuous healthy environment for staff, patients and public in Nuclear Medicine Department.

Graphene-oxide-based metal hybrids (GM) are used for the rapid and efficient reduction and removal of toxic adulterants in the environment. The exceptionally high specific surface area, versatile surface chemistry, and exceptional customization efficiency of graphene oxide nanosheets combined with the adaptable chemistry of metal nanoparticles enable the formation of GM hybrid nanocomposites. However, little is known about the architecture of GM nanocomposite engineering, interaction mechanisms, and environmental compatibility. This review aims to describe the environmental performance of graphene oxide–metal hybrids for the removal of environmental pollutants, carbon capture, EMI shielding efficiency, and microbial elimination of engineered graphene oxide composites anchored with metal particles. We also developed an essential link between the material properties of GM nanohybrids and their performance, which identified the fundamental parameters that influence the contaminant removal capability and EMI resistance efficiency. The influence of the thermodynamic parameters of GM on the adsorption of radioisotopes, heavy metals, organic pollutants, and dyes was considered. Finally, we comment on the remaining challenges and provide suggestions for future developments in this field.
