Sokol, John Buckeridge, David O. Scanlon & C. Richard A. Catlow doi:10.1038/s41563-018-0165-7 This Perspective explores the history and usage of the concept of oxidation state, its relation to atomic charge and bonding, and opportunities that arise from applying this analysis to systems with mixed valence or correlated electrons. Letters Interparticle hydrogen bonding can elicit shear jamming in dense suspensions    pp965 - 970 Nicole M. James, Endao Han, Ricardo Arturo Lopez de la Cruz, Justin Jureller & Heinrich M. Jaeger doi:10.1038/s41563-018-0175-5 Dense suspensions of hard particles readily display discontinuous shear thickening under shear but not reversible shear jamming. Here it is shown that the formation of interparticle hydrogen bonds is crucial for the shear jamming of these suspensions. Therapeutic treatment of Zika virus infection using a brain-penetrating antiviral peptide    pp971 - 977 Joshua A. Jackman, Vivian V. Costa, Soohyun Park, Ana Luiza C. V. Real, Jae Hyeon Park et al. doi:10.1038/s41563-018-0194-2 The Zika virus infects the central nervous system and results in severe brain malformation. An amphiphatic peptide is now shown to penetrate the blood–brain barrier, reducing viral loads due to its activity against Zika and other mosquito-borne viruses. Articles Topological quantum properties of chiral crystals    pp978 - 985 Guoqing Chang, Benjamin J. Wieder, Frank Schindler, Daniel S. Sanchez, Ilya Belopolski et al. doi:10.1038/s41563-018-0169-3 Kramers–Weyl fermions are identified in chiral crystals, and their phenomenology is drawn out. Efficient electrical detection of mid-infrared graphene plasmons at room temperature    pp986 - 992 Qiushi Guo, Renwen Yu, Cheng Li, Shaofan Yuan, Bingchen Deng et al. doi:10.1038/s41563-018-0157-7 A system of patterned graphene nanoresonators/nanoribbons can be used as an efficient mid-infrared detector, based on plasmonic resonant absorption and subsequent carrier thermalization. On-chip valley topological materials for elastic wave manipulation    pp993 - 998 Mou Yan, Jiuyang Lu, Feng Li, Weiyin Deng, Xueqin Huang et al. doi:10.1038/s41563-018-0191-5 Topologically protected edge states can be observed when combining two Si-based phononic crystals of opposite phases, as well as on-chip elastic wave splitting via partition of edges states at the intersection of topological channels. Polarity governs atomic interaction through two-dimensional materials    pp999 - 1004 Wei Kong, Huashan Li, Kuan Qiao, Yunjo Kim, Kyusang Lee et al. doi:10.1038/s41563-018-0176-4 Remote atomic interaction of crystalline materials through 2D materials is presented to depend on the polarity of both the 2D interlayers and underlying substrates, providing insights for the epitaxial growth of various materials on 2D crystals. Autoperforation of 2D materials for generating two-terminal memristive Janus particles    pp1005 - 1012 Pingwei Liu, Albert Tianxiang Liu, Daichi Kozawa, Juyao Dong, Jing Fan Yang et al. doi:10.1038/s41563-018-0197-z A technique of autoperforation is presented to fabricate colloidal microparticles with functional polymer composite enveloped by two sheets of 2D materials.
