Chapter 3:Nanoparticles in the Atmosphere Currently, the main exposures of the general population to nanoparticles are likely to arise from breathing the air. Nanoparticles are very abundant in the... R Harrison 被引量: 11发表: 2007年 The Impact of Chemical Aging on Ice Nucleating Abilities of...

In many cases it is unavoidable that nanoparticles are released into the environment, either during the production processes or during the use of a product made from these particles. It is also realized that combustion processes like traffic and power plants release nanoparticles into the atmosphere....
Health impacts related to particulate matter (PM) in the atmosphere have been investigated (Ramakreshnan et al., 2017; Ho et al., 2018; Ho et al., 2019). Life has been shortened by ~1.2-1.9 years by PM2.5 exposure in polluted Asian and African countries (Apte et al., 2018). It ...
in most artificial additions, their efficiencies in CO2drawdown are much less than those observed for naturally occurring fertilization, for example, via terrestrial dust deposition through the atmosphere6. Slow export rates of biomass, especially if not enhanced compared to remineralization rates (the ...
A Simple Way to Synthesize Superparamagnetic Iron Oxide Nanoparticles in Air Atmosphere: Iron Ion Concentration Effect We have synthesized iron oxide nanoparticles in air atmosphere by coprecipitation. The ratio of was fixed at 2/3. The total amount of iron ions in the solu... O Karaagac,H ...
A capacitive-type counter of nanoparticles in air, based on measurement of the capacitance of a capacitor with a variable dielectric part, has been developed. The method is suitable for detection of aerosols in a wide concentration range, regardless of shape or chemical composition. The method is...
This research examines the oxidation mechanism of nano-Ta by replicating an ultra-fast heating environment in an electron microscope as well as in an oxygenated atmosphere. 展开 关键词: Pedicularis furbishiae metapopulation model Colonization occupancy extinction Furbish???s lousewort Saint John River ...
The quantum confined absorption peak of Cu2O was not affected by heat-treatment in N2 or Ar. Cu2O nanoparticles were reduced by heat-treatment at 250 degrees C in 5% H2 atmosphere and a new SPR peak appeared. Our results show that Cu nanoparticles are easily oxidized and highly dense Cu ...
