This study aims to investigate the role of impact angles on the de-agglomeration performance of powders for inhalation.
These results disclose that small Co particles and the uniform dispersion are beneficial for obtaining a high-performance Co-PPy-TsOH/C catalyst towards ORR, while large cobalt particles and the agglomeration deteriorate the catalytic performance.
The high reactivity of the oxygen carrier maintained during the whole test, the low attrition rate detected after 100 h of operation, and the absence of any agglomeration problem revealed a good performance of these CuO-based materials as oxygen carriers in a CLC process.
However, higher loading of the nanoparticulates may result in agglomeration and reduce the separation performance.
The theoretical capacity of metallic Ag was 993 mAh g−1 (for Li4Ag), although it suffered from severe volume expansion and agglomeration, leading to poor cycling performance.
They also indicated that a combination of these two nanoparticles would lead to agglomeration and reduces the overall performance of the cement mortar.
The quality of aerosol dispersion (i.e. de-agglomeration) and associated lung targeting performance was assessed by measuring the total lung dose (TLD) using the Alberta idealized mouth throat model.
In these cases, a TiO2 agglomeration was observed and the barrier performance decreased.
Operational difficulties like agglomeration, gas refluxing, back-sifting and performance related issues like emission control and bed temperature control are also examined.
