The changes produced in an activated carbon by treatment in aqueous solutions of (NH 4 ) 2 S 2 O 8 and H 2 O 2 are compared with the modifications produced by oxygen plasma. These changes are monitored by measuring the textural characteristics (surface areas, porosity, pore size distributions) and s

## Abstract Careful curve fitting is needed when using XPS to investigate oxidized functional groups on carbon‐fibre surfaces. This is important because the core regions often contain a number of overlapping features some of which are of low intensity, and the C 1s region is influenced by an asymme
## Abstract Some data related to the preparation of carbon fibre composites is summarised. A limited investigation concerned with presenting markedly different fibre surfaces to the resin by coating with metals and stearic acid is also described. There are carbon fibre surface treatments which le
An activated carbon obtained from olive stones and with very low ash content (0.10%) was treated with either HCI, HF or HNO,. The changes in surface area and porosity resulting from the acid treatments were studied by N, and CO, adsorption at 77 and 273 K, respectively and by mercury porosimetry. Th
