a simple method to synthesize nanowires titanium dioxide from layered titanate particles

... used as the annealing temperature because nanowires react to become SiO vapor and disappear above this temperature [21]. During annealing, a total pres- sure of 740 Torr was maintained. Afterwards, small ... defects after annealing. Raman spectra also con®rmed that the bulk specimen was almost defect-free. By using thermal annealing, defect-free silicon nanowires can be prepared in a...

... that I can create a dedicated /home partition using LVM - and if I need more space I can extend it. In this example hda1, hda2, and hda3 are all physical volumes. We'll initialize hda3 as ... lvm2 Now that we have a volume group (called skx-vol) we can actually start using it. Working with logical volumes What we really want to do is create logical volumes which we can mount and...
