By using the density function theory (DFT) the adsorption of nitramine (NH2NO2) molecule on the surface of pristine and Ni functionalized of Gallium nitride nanotube (GaNNTs) is investigated. The adsorption energy of NH2NO2 molecule on the surface of pristine and Ni functionalized GaNNTs is in range ‒6.59 to ‒48.16 Kcal/mol and is physisorption type. The ∆E and ∆H values of the all adsorption m...

The worldwide dispersion and sudden emergence of new antibiotic resistance genes (ARGs) determined the need in uncovering which environment participate most as their source and reservoir. ARGs closely related to those currently found in human pathogens occur in the resistome of anthropogenic impacted environments. However, the role of pristine environment as the origin and source of ARGs remain...

Polar regions have long acted as a chemical sink for the planet—locking away pollutants. Understanding how pollutants travel from temperate to poles is priority of environmental chemists, especially climate change intensifies problem pollution. Answers will be key creating livable Arctic. For 300 polar bears that call Svalbard, Norway, home, rocky archipelago between top Norway and North Pole r...

Continental Antarctic is perceived as a largely pristine environment, although certain localized regions (e.g., parts of the Ross Dependency Dry Valleys) are relatively heavy impacted by human activities. The procedures imposed on Antarctic field parties for the handling and disposal of both solid and liquid wastes are designed to minimise eutrofication and contamination (particularly by human ...

Tibetans view the environment as an interrelated balance upon which humans and nature coexist. Overconsumption of resources is discouraged, and the taking of life is forbidden by Buddhist practice. However, as traditional people meet the modern world, checkerboard patterns are carved into forested mountain slopes, pollution runs freely in once pristine waters, erosion lays grasslands bare, and ...

The growing use of carbon nanotubes (CNTs) in industrial and consumer products raises important questions about their environmental fate and impact on prokaryotes. In the environment, CNTs are exposed to a variety of conditions (e.g., UV light) that could lead to decomposition and changes in their chemical properties. Therefore, the potential cytotoxic effect of both pristine and artificially a...

The solvent evaporation method on the structural changes and surface chemistry of the cathode and the effect of electrochemical performance of Li1.0Ni0.8Co0.15Mn0.05O2 (NCM) has been investigated. After dissolving of Li residuals using minimum content of solvent in order to minimize the damage of pristine material and the evaporation time, the solvent was evaporated without filtering and remain...

[ 22 ] Thus, given the widespread presence of H 2 O 2 in the body and environment, and the future impact graphene may have on human health and environment, systematic studies need to be performed to investigate the direct chemical interaction between H 2 O 2 and graphe...

abstract: electrical sensitivity of a beryllium oxide nanotube (beont) was examined toward (c5h5n) molecule by using density functional theory (dft) calculations at the b3lyp/6-31(d) level, and it was found that the adsorption energy (ead) of pyridine on the pristine nanotubes is   a bout -73.29kcal/mol. but when nanotubes has been doped with s and p atomes , the adsorption energy changed . cal...

Multi-walled carbon nanotubes (MWNTs) are increasingly being developed both as neuro-therapeutic drug delivery systems to the brain and as neural scaffolds to drive tissue regeneration across lesion sites. MWNTs with different degrees of acid oxidation may have different bioreactivities and propensities to aggregate in the extracellular environment, and both individualised and aggregated MWNTs ...
