Hydrophobic and hydrophilic surface properties - depending on the chosen treatment conditions - allow the separation and storage of liquid chemical compounds. Activation of the carbonaceous structures substantially increases the specific surface area from ~4\u2005m<jats:sup>2<\/jats:sup>g<jats:sup>\u22121<\/jats:sup> to ~345\u2005m<jats:sup>2<\/jats:sup>g<jats:sup>\u22121<\/jats:sup>, while retaining the original three-dimensional, open-pore structure suitable for hosting, for example, Ni catalyst nanoparticles. In turn the structure is rendered suitable for hydrogenating acetone to 2-propanol and methyl isobutyl ketone as well for growing hierarchical carbon nanotube structures used as electric double-layer capacitor electrodes with specific capacitance of ~40\u2005F\/g. Mechanical stress-strain analysis indicates the materials are super-compressible (&gt;70% volume reduction) and viscoelastic with excellent damping behavior (loss of 0.69 \u00b1 0.07), while piezoresistive measurements show very high gauge factors (from ~20 to 50) over a large range of deformations. The cost-effective, robust and scalable synthesis - in conjunction with their fascinating multifunctional utility - makes the demonstrated carbon foams remarkable competitors with other three-dimensional carbon materials typically based on pyrolyzed biopolymers or on covalently bonded graphene and carbon nanotube frameworks.<\/jats:p>","DOI":"10.1038\/srep06933","type":"journal-article","created":{"date-parts":[[2014,11,6]],"date-time":"2014-11-06T13:48:36Z","timestamp":1415281716000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":29,"title":["Industrially benign super-compressible piezoresistive carbon foams with predefined wetting properties: from environmental to electrical applications"],"prefix":"10.1038","volume":"4","author":[{"given":"Tung Ngoc","family":"Pham","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ajaikumar","family":"Samikannu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jarmo","family":"Kukkola","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anne-Riikka","family":"Rautio","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Olli","family":"Pitk\u00e4nen","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Aron","family":"Dombovari","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gabriela Simone","family":"Lorite","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Teemu","family":"Sipola","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Geza","family":"Toth","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Melinda","family":"Mohl","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jyri-Pekka","family":"Mikkola","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Krisztian","family":"Kordas","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2014,11,6]]},"reference":[{"key":"BFsrep06933_CR1","doi-asserted-by":"publisher","first-page":"5989","DOI":"10.1021\/cr100059s","volume":"110","author":"K Yang","year":"2010","unstructured":"Yang, K. & Xing, B.
