Cellulose in maize is an ideal candidate for a sustainable and renewable energy source because of its global abundance. X-ray scattering has been used as an experimental technique to study cellulose fibrils during processing. In order to understand the impact of chemical or physical treatments on structural parameters such as diameter, twist and coiling, we are simulating X-ray scattering from large...
The local structure around Cu in ${\rm Fe}_{85}{\rm Si}_{2}{\rm B}_{8}{\rm P}_{4}{\rm Cu}_{1}$ (NANOMET) and ${\rm Fe}_{85}{\rm Si}_{2}{\rm B}_{12}{\rm Cu}_{1}$ alloys was investigated by X-ray absorption fine structure (XAFS) and analytical transmission electron microscopy (TEM). The XAFS measurements indicate that the local structure around Cu atoms for the nanocrystallized ${\rm Fe}_{85}{\rm Si}_{2}{\rm B}_{8}{\rm P}_{4}{\rm Cu}_{1}$ ...
This paper studies the relation of nanopore diameter to film thickness and FIB action time with focus ion beam (FIB). First, the fabrication process for free-standing silicon nitride (Si3N4) films was introduced and got 300 nm and 200 nm thick film at last. Then, a series of pores with different diameters were milled on films under different FIB action time. Subsequently, the relation was analyzed...
