| The surface of the suspension became matt, a painted slash of colour against the grey rock, as microfine tremors shot through it. |
|
| The principal UVB absorbers are para-aminobenzoic acid derivatives, salicylates, cinnamates and camphor derivatives and microfine titanium dioxide. |
|
| Other hybrid composites have a combination of colloidal and fine particles, and have better compressive and tensile strength properties than the microfine variety. |
