See also: Article by Liu et al. Organic electronics: Organic thin-film magnetometers   pp663 - 664 Joseph Shinar doi:10.1038/nmat3390 Magnetometry usually requires large probes and bulky instrumentation. Organic diodes have now been used in small probes that can measure moderate magnetic fields with 10 ppm precision. Hydrogels: The catalytic curtsey   pp665 - 666 Eugenia Kumacheva doi:10.1038/nmat3381 A polymer hydrogel system combines chemical, thermal and mechanical responses in a reversible manner and thus exhibits homeostatic and self-regulatory behaviour similar to that of living systems. Material witness: Two ways to relax   p666 Philip Ball doi:10.1038/nmat3389 Nature Materials JOBS of the week PhD position 2: Novel catalytic materials based on nanocomposites for water gas shift reaction and selective carbon monoxide oxidation Istituto Italiano di Tecnologia ( Dual PhD issued by University of Genoa together with the University of Tarragona, Spain) Permanent Researcher- Nanostructured Semiconducting Materials Group National Institute for Materials Science (NIMS) Asst. / Assoc.

This Review discusses current understanding of the interface between water and flat metal surfaces at the atomic and molecular levels, as well as open questions in this field. Letters Top Long-range transfer of electron–phonon coupling in oxide superlattices   pp675 - 681 N. Driza, S. Blanco-Canosa, M. Bakr, S. Soltan, M. Khalid, L. Mustafa, K. Kawashima, G. Christiani, H-U. Habermeier, G. Khaliullin, C. Ulrich, M. Le Tacon and B. Keimer doi:10.1038/nmat3378 The interaction between electrons and phonons is important for many materials properties. The finding that phonon modes of a superconducting thin film can influence the properties of an adjacent normal conductor, even over comparatively long distances, suggests new ways of controlling electron–phonon interactions. High intergrain critical current density in fine-grain (Ba0.6K0.4)Fe2As2 wires and bulks   pp682 - 685 J. D. Weiss, C. Tarantini, J. Jiang, F. Kametani, A. A. Polyanskii, D. C. Larbalestier and E. E. Hellstrom doi:10.1038/nmat3333 Although fundamentally intriguing, iron-based superconductors have not been seriously considered for applications because of the limited superconducting current that has so far been observed in wires made from these materials. It is now shown that by following a specific synthesis procedure it is possible to achieve superconducting currents that are close to commercial requirements. Spin-current-driven thermoelectric coating   pp686 - 689 Akihiro Kirihara, Ken-ichi Uchida, Yosuke Kajiwara, Masahiko Ishida, Yasunobu Nakamura, Takashi Manako, Eiji Saitoh and Shinichi Yorozu doi:10.1038/nmat3360 A thin layer of yttrium iron garnet coating on different materials can transform wasted heat into voltage. The process is based on the spin Seebeck effect and could lead to new types of application that make use of omnipresent wasted heat. Al13Fe4 as a low-cost alternative for palladium in heterogeneous hydrogenation   pp690 - 693 M. Armbrüster, K. Kovnir, M. Friedrich, D. Teschner, G. Wowsnick, M. Hahne, P. Gille, L. Szentmiklósi, M. Feuerbacher, M. Heggen, F. Girgsdies, D. Rosenthal, R. Schlögl and Yu. Grin doi:10.1038/nmat3347 Replacing noble metals in heterogeneous catalysts by low-cost and ubiquitous substitutes such as iron is highly desirable especially because it does not bear potential health risks. A low cost and environmentally benign intermetallic compound Al13Fe4 is now identified as an active and selective semi-hydrogenation catalyst, which could prove to be applicable to a wide range of heterogeneously catalysed reactions. Articles Top Solitonic lattice and Yukawa forces in the rare-earth orthoferrite TbFeO3    pp694 - 699 Sergey Artyukhin, Maxim Mostovoy, Niels Paduraru Jensen, Duc Le, Karel Prokes, Vinícius G. de Paula, Heloisa N. Bordallo, Andrey Maljuk, Sven Landsgesell, Hanjo Ryll, Bastian Klemke, Sebastian Paeckel, Klaus Kiefer, Kim Lefmann, Luise Theil Kuhn and Dimitri N. Argyriou doi:10.1038/nmat3358 The interaction between spins in magnetic materials gives rise to a number of interesting effects. An example is the discovery of an unusual magnetic state based on a long-range ordering force between magnetic domain walls that is analogous to the interaction between protons and neutrons in atomic nuclei. Ferroelectric order in individual nanometre-scale crystals   pp700 - 709 Mark J. Polking, Myung-Geun Han, Amin Yourdkhani, Valeri Petkov, Christian F. Kisielowski, Vyacheslav V. Volkov, Yimei Zhu, Gabriel Caruntu, A. Paul Alivisatos and Ramamoorthy Ramesh doi:10.1038/nmat3371 The length scale at which phenomena such as ferroelectricity is still present is of fundamental relevance for nanoscale applications. A high-resolution transmission electron microscopy study now shows how ferroelectricity can persist in nanoparticles down to about 5 nm in diameter, pointing the way towards the ultimate size limit for ferroelectric applications. A partially interpenetrated metal–organic framework for selective hysteretic sorption of carbon dioxide    pp710 - 716 Sihai Yang, Xiang Lin, William Lewis, Mikhail Suyetin, Elena Bichoutskaia, Julia E. Parker, Chiu C. Tang, David R. Allan, Pierre J. Rizkallah, Peter Hubberstey, Neil R. Champness, K. Mark Thomas, Alexander J. Blake and Martin Schröder doi:10.1038/nmat3343 The selective capture of carbon dioxide in porous materials has potential for the storage and purification of fuel gases, but strategies to enhance carbon dioxide–host selectivity are required. A partially interpenetrated metal–organic framework that undergoes dramatic phase transition on desolvation and exhibits temperature-dependent selective hysteretic sorption of carbon dioxide is now reported. Mesoscopic architectures of porous coordination polymers fabricated by pseudomorphic replication   pp717 - 723 Julien Reboul, Shuhei Furukawa, Nao Horike, Manuel Tsotsalas, Kenji Hirai, Hiromitsu Uehara, Mio Kondo, Nicolas Louvain, Osami Sakata and Susumu Kitagawa doi:10.1038/nmat3359 The spatial organization of porous coordination-polymer crystals into higher-order structures is critical for their integration in heterogeneous catalysts, separation systems and electrochemical devices. A method for spatially controlling the nucleation site leading to the formation of mesoscopic architecture in porous coordination polymers, in both two and three dimensions, is now demonstrated. The predominant role of collagen in the nucleation, growth, structure and orientation of bone apatite   pp724 - 733 Yan Wang, Thierry Azaïs, Marc Robin, Anne Vallée, Chelsea Catania, Patrick Legriel, Gérard Pehau-Arnaudet, Florence Babonneau, Marie-Madeleine Giraud-Guille and Nadine Nassif doi:10.1038/nmat3362 Calcium-rich non-collagenous proteins in the extracellular matrix of bone are believed to be involved in the different steps of bone mineralization. It is now shown that in the absence of these proteins collagen can initiate and orient growing apatite crystals in vitro, and influence both their structural characteristics on the atomic scale and their larger-scale three-dimensional distribution in bone. Soft fibrin gels promote selection and growth of tumorigenic cells   pp734 - 741 Jing Liu, Youhua Tan, Huafeng Zhang, Yi Zhang, Pingwei Xu, Junwei Chen, Yeh-Chuin Poh, Ke Tang, Ning Wang and Bo Huang doi:10.1038/nmat3361 Conventional methods for the selection of tumorigenic cells from cancer cell lines rely on stem-cell markers. It is now shown that soft fibrin gels promote the growth of colonies of tumorigenic cells from single cancer cells from mouse or human cancer cell lines, and that as few as ten fibrin-cultured cells can lead to the formation of tumours in mice more efficiently than marker-selected cells.
