      abstract     = {I study how the contact area and the work of adhesion
                      between two elastic solids with randomly rough surfaces
                      depend on the relative humidity. The surfaces are assumed to
                      be hydrophilic, and capillary bridges form at the interface
                      between the solids. For elastically hard solids with
                      relatively smooth surfaces, the area of real contact and
                      therefore also the sliding friction are maximal when there
                      is just enough liquid to fill out the interfacial space
                      between the solids, which typically occurs for d(K)
                      approximate to 3h(rms), where d(K) is the height of the
                      capillary bridge and h(rms) the root-mean-square roughness
                      of the (combined) surface roughness profile. For elastically
                      soft solids, the area of real contact is maximal for very
                      low humidity (i.e. small d(K)), where the capillary bridges
                      are able to pull the solids into nearly complete contact. In
                      both cases, the work of adhesion is maximal (and equal to 2
                      gamma cos theta, where gamma is the liquid surface tension
                      and theta the liquid-solid contact angle) when d(K) >>
                      h(rms), corresponding to high relative humidity.},
