AIMResearch - Highlighting research from the Advanced Institute for Materials Research (AIMR) in Japan, which promotes mathematics-materials science collaboration http://research.wpi-aimr.tohoku.ac.jp/
Membrane materials offer many practical advantages for purification and separation applications. In this Focus issue we highlight the most promising new membrane materials that offer competitive performance capabilities, and discuss how to transfer such materials and processes to industry.
The state of flux p275 doi:10.1038/nmat4877 The development of new membrane materials for chemical separations is progressing rapidly, and their commercial success will require a more concerted effort from academia and industry.
Membranes from academia to industry pp280 - 282 Interview with Andrew Livingston & Richard Baker doi:10.1038/nmat4861 Andrew Livingston (Imperial College London) and Richard Baker (Membrane Technology and Research) talk to Nature Materials about the perks and pitfalls of membrane research and development, and how activities at the new Barrer Centre might lead to next-generation separation technologies.
Porous materials: Lining up metal–organic frameworks pp283 - 284 Neil R. Champness doi:10.1038/nmat4859 A new report demonstrates an innovative approach to aligning crystallites of metal–organic frameworks such that thin films are created with oriented channels — potentially overcoming one of the major barriers to application of these highly topical materials.
Glasses: Achieving long phonon lifetimes pp285 - 286 Maxim Goryachev and Michael E. Tobar doi:10.1038/nmat4867 Spectral hole burning is now demonstrated with phonons in amorphous systems, leading to highly reduced phonon dissipation and, therefore, long phonon lifetimes.
Current-induced switching in a magnetic insulator pp309 - 314 Can Onur Avci, Andy Quindeau, Chi-Feng Pai, Maxwell Mann, Lucas Caretta et al. doi:10.1038/nmat4812 Spin-current-induced magnetization reversal of a perpendicularly magnetized thulium iron garnet film is reported. The spin current is driven by the current flowing through a Pt overlayer.
Engineering dissipation with phononic spectral hole burning pp315 - 321 R. O. Behunin, P. Kharel, W. H. Renninger and P. T. Rakich doi:10.1038/nmat4819 Acoustically opaque glass can regain its transparency through coherently driven fields. Combining experiments and theory, the phononic saturation process is presented as analogous to the spectral hole burning process.
