Graphene is a promising candidate for CO2 capture, storage, and sensor. Doping graphene with other elements is an effective way to modify its CO2 storage ability. The literature has shown that the N and B dopants could change the adsorption strength of CO2 on the graphene substrate.

"Germanene as potential material for sensor of toxic gases CO2, SO2, and CH4: A DFT study" show that gases of CO2, SO2, and CH4 are physically adsorbed on germanene via a charge transfer mechanism. The physisorption of these gas molecules on germanene opens a band gap at the Dirac point of germanene. The different adsorption behaviors of gas molecules on germanene provide a feasible way to extend germanene for gas sensors.

During a hypothetical severe accident in a nuclear reactor most of the radioactivity would be released from the damaged core and the broken primary circuit in the form of aerosols and chemical vapours and gases. However the effective radio-toxicity per unit release from the fuel depends both on the released mass and on the chemical form as well.

In this study, the adsorption configuration, adsorption energy of toxic gas molecules (CO, NO, CO2, NH3, and NO2) on B12 – borophene was investigated by first – principle calculations using three van der Waals correlation functionals: RevPBE-vdW, optPBE-vdW, and vdW-DF2.

In this work, the adsorption ability of β12 borophene towards some main harmful gases was investigated. The first-principles calculations were employed to obtain the adsorption configurations and the adsorption energies of CO, NO, CO2, NH3, and NO2 on 12 borophene. The vdW interactions are taken into account by using three functionals: revPBE-vdW, optPBE-vdW, and vdW-DF2.

Plastics are widely used for manufacturing of packaging materials because of their performance and ease in production. With the advent of food processing industries there is a great demand for petroleum based packaging materials for food applications. However, because of their resistance to biodegradation, increased use of plastics has created serious ecological problems to the environment. Moreover burning these plastic materials produce toxic gases which are very much injurious to both flora and fauna. Food industry is a major consumer of plastic as a packing material for the food items.

Iron oxide nanorods were synthesized by chemical co-precipitation method. The structural and morphological characteristics of the as-synthesized nanorods were analyzed by Xray diffraction (XRD) and scanning electron microscopy. The results show that the iron oxide nanorods include the mixture of Fe3O4, γ-Fe2O3 and FeOOH with the diameter and the length of iron oxide nanorods to be 30 and 100 nm, respectively. The iron oxide nanorods were then dispersed and deposited on the gold electrode of quartz crystal microbalance (QCM) for the gas sensor.

The scientific evidence is now overwhelming: climate change presents very serious global risks, and it demands an urgent global response. This independent Review was commissioned by the Chancellor of the Exchequer, reporting to both the Chancellor and to the Prime Minister, as a contribution to assessing the evidence and building understanding of the economics of climate change. The Review first examines the evidence on the economic impacts of climate change itself, and explores the economics of stabilising greenhouse gases in the atmosphere.

The air pollution accumulating in the interior of automobiles consists almost exclusively of gaso- line and diesel exhaust. This toxic soup of gases, aerosols, and microscopic particles includes ben- zene (a known carcinogen), carbon monoxide (which interferes with the blood’s ability to trans- port oxygen), particulate matter (which studies have associated with increased death rates), and a host of other hazardous chemicals.

It is not yet clear how exposure to low ambient concentrations of particulates might produce the health effects observed in epidemiological studies and whether certain attributes of particles may be more closely associated to these health effects. The characteristics of particles that are being investigated for their roles in causing health effects include metal content, particle size, and particles as carriers of other toxic compounds (such as gases or biological toxins from bacteria and pollens etc.).

By inadvertently increasing the concentration of energy-trapping gases in the lower atmosphere, human actions have begun to amplify Earth’s natural green- house effect. The primary challenge facing the world community is to achieve sufficient reduction in greenhouse gas emissions so as to avoid dangerous inter- ference in the climate system. National governments, via the UN Framework Convention on Climate Change (UNFCC), are committed in principle to seeking this outcome.

Greenhouse gases such as CO2 and methane are believed to contribute to global warming. Dust is a common problem throughout all mining activities. Dust generated by vehicle traffic can be reduced through a variety of means. Where water resources are not limited, regular watering with mobile water trucks or fixed sprinkler systems is effec- tive. Otherwise the application of surface binding agents, the selection of suitable construction materials and the sealing of heavily used access ways may be more suitable.

The burning of fossil fuels puts into the atmosphere carbon dioxide, which is causing gradual global warming. This 'greenhouse effect' may by early next century have increased average global temperatures enough to shift agricultural production areas, raise sea levels to flood coastal cities, and disrupt national economies.
