By additional ion irradiation during the secondary etching process, cleaning of the surface and a decrease in the thickness of the Fe catalyst is to be expected, and these result in a decrease in the roughness and a consequent improvement in the height, uniformity, and quality of CNTs.
However the methods used (reusable sample chambers) was suboptimal: a significant cell loss can be attributed to the roughness of sample chamber walls secondary to repeated cleaning [ 13].
Secondary emissions generated from cleaning chemicals reaction with ozone, which have been investigated by experimental studies [ 17], may also be important to consider when developing quantitative workplace exposure assessment strategies.
For Oscar, a spontaneous, free spirited adventurer, cleaning up was secondary.. On the other side, Felix saw himself as a provider, role model and leader, fostering a home environment that was clean and pleasant.
These authors further showed that secondary organic pollutants formed from cleaning products exist in the lowest range of exposure and that a higher concentration of particulates is formed by peeling an orange.
Convergent nozzle induces more secondary flow and generates higher pulse cleaning effect than straight nozzle.
Tar removal technologies can broadly be divided into two approaches; hot gas cleaning after the gasifier (secondary methods), and treatments inside the gasifier (primary methods).
If secondary infection of the spots occurs, cleaning the area with salt water or cleansing shampoo will help control the problem but they will not solve it.
Secondary objectives include the minimization of pipeline cleaning operations, the minimization of lead times, and the balanced utilization of filling units.
It then addresses the secondary gas treatment covering the most critical gas cleaning up and gas conditioning stages.
