Sentences with phrase «as micrometre»

The discovery is significant, as micrometre - sized particles are easier and safer to process than nanoparticles.

Not exact matches

Most of this plastic disintegrates into particles smaller than five millimetres, referred to as microplastics, and breaks down further into nanoparticles, which are less than 0.1 micrometre in size.

Various forces such as surface adhesion or electrostatic charge cause the particles to adhere to each other in systems with extremely small particles measuring only a few micrometres.

The shorter time for drug delivery is made possible as the miniature needles on the patch create micrometre - sized porous channels in the skin to deliver the drug rapidly.

These tiny polymer scaffolds contain channels that are about 100 micrometres wide, about the same diameter as a human hair.

But he added that a small panel with printed details as small as 3 micrometres had already been made, and this was achievable by lithography.

The microfilm is made by depositing 3 to 7 micrometres of the solid liquid crystal on a sheet of PET, the transparent plastic from which some fizzy drink bottles are made, which acts as a support.

By using the most concentrated hydrofluoric acid available, the pores can be made as small as one to two nanometres wide, but many micrometres long.

However, the transparency of silicon only extends up to eight micrometres (μm) and is therefore not very suitable as a core material for the mid-IR fingerprint band (8 - 14 μm).
