Growth and characterization of carbon nanofibers by a technique of polymer doped catalyst and hot-filament chemical vapor deposition
(Pergamon-elsevier Science LtdOxfordInglaterra, 2008)
Remarks concerning the emission rates in super strong magnetic fields
(Universidad Nacional de Costa Rica, 2016)
PM10 emission efficiency for agricultural soils: Comparing a wind tunnel, a dust generator, and the open-air plot
(Elsevier, 2018-06)
The PM10 emission efficiency of soils has been determined through different methods. Although these methods imply important physical differences, their outputs have never been compared. In the present study the PM10 emission ...
Stress-induced electron emission from nanocomposite amorphous carbon thin films
(Amer Inst PhysicsMelvilleEUA, 2002)
Measurement and control of greenhouse gas emissions from beef cattle feedlots
(2013-05-01)
Emission of greenhouse gases (GHGs), including nitrous oxide (N2O), methane (CH4), and carbon dioxide (CO2), from open beef cattle feedlots is becoming an environmental concern; however, scientific information on emissions ...
Gross, background, and net anthropogenic soil nitrous oxide emissions from soybean, corn, and wheat croplands
(American Society of Agronomy, 2019-01)
Agricultural soils are the largest single source of N2O emissions globally. However, soils left uncultivated would still release N2O. Distinguishing anthropogenic from natural emissions (i.e., background emissions) in crops ...
Silicon Field-Emission Devices Fabricated Using the Hydrogen Implantation-Porous Silicon (HI-PS) Micromachining Technique
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2008)
This paper presents a relatively simple method to fabricate field-emitter arrays from silicon substrates. These devices are obtained from silicon micromachining by means of the HI-PS technique-a combination of hydrogen ion ...
Experimental research on the effects of water application on greenhouse gas emissions from beef cattle feedlots
(2014-04-30)
The effect of water application (e.g., through rainfall or sprinkler system) on emissions of greenhouse gases (GHGs), such as nitrous oxide (N2O), methane (CH4), and carbon dioxide (CO2), from pen surfaces of open-lot beef ...
A statistical evaluation of the field emission for copper oxide nanostructures
(ELSEVIER SCIENCE BV, 2008)
A statistical data analysis methodology was developed to evaluate the field emission properties of many samples of copper oxide nanostructured field emitters. This analysis was largely done in terms of Seppen-Katamuki (SK) ...
