Gaudin, C. Fourment, B. I. Cho et al.     The rapidly growing ultrafast science with X-ray lasers unveils atomic scale processes with unprecedented time resolution bringing the so called “molecular movie” within reach. …             Recalcitrant bubbles ▶     Martin E. R. Shanahan, Khellil Sefiane     We demonstrate that thermocapillary forces may drive bubbles against liquid flow in ‘anomalous’ mixtures. Unlike ‘ordinary’ liquids, in which bubbles migrate towards higher …             Planar-defect-rich zinc oxide nanoparticles assembled on carbon nanotube films as ultraviolet emitters and photocatalysts ▶     Yunqing Zhu, Xiaohua Zhang, Ru Li et al.     Structural defects in zinc oxide (ZnO) nanoparticles are complex and hard to be controlled during the synthesis, however, diversifying the chemical and physical performances. Here …             Origin of subdiffusion of water molecules on cell membrane surfaces ▶     Eiji Yamamoto, Takuma Akimoto, Masato Yasui et al.     Water molecules play an important role in providing unique environments for biological reactions on cell membranes. It is widely believed that water molecules form bridges that …             A unified intermediate and mechanism for soot combustion on potassium-supported oxides ▶     Qian Li, Xiao Wang, Ying Xin et al.     The soot combustion mechanism over potassium-supported oxides (MgO, CeO2 and ZrO2) was studied to clarify the active sites and discover unified reaction intermediates in this …             Automated single-cell motility analysis on a chip using lensfree microscopy ▶     Ivan Pushkarsky, Yunbo Lyb, Westbrook Weaver et al.     Quantitative cell motility studies are necessary for understanding biophysical processes, developing models for cell locomotion and for drug discovery. Such studies are typically …             A visible metamaterial fabricated by self-assembly method ▶     Boyi Gong, Xiaopeng Zhao, Zhenzhen Pan et al.     A visible negative-index metamaterial was fabricated by adopting a template-assisted and self-assembled electrochemical deposition method. Originating from the inherent …             Only the chemical state of Indium changes in Mn-doped In3Sb1Te2 (Mn: 10 at.%) during multi-level resistance changes ▶     Y. M. Lee, D. Ahn, J.-Y. Kim et al.     We fabricated and characterized the material with Mn (10 at.%: atomic percent) doped In3Sb1Te2 (MIST) using co-sputtering and synchrotron radiation, respectively. The MIST thin …             Correlative Tomography ▶     T. L. Burnett, S. A. McDonald, A. Gholinia et al.     Increasingly researchers are looking to bring together perspectives across multiple scales, or to combine insights from different techniques, for the same region of interest. To …             Increasing Mechanical Strength of Gelatin Hydrogels by Divalent Metal Ion Removal ▶     Qi Xing, Keegan Yates, Caleb Vogt et al.     The usage of gelatin hydrogel is limited due to its instability and poor mechanical properties, especially under physiological conditions. Divalent metal ions present in gelatin …             Thermalization of field driven quantum systems ▶     H. Fotso, K. Mikelsons, J. K. Freericks     There is much interest in how quantum systems thermalize after a sudden change, because unitary evolution should preclude thermalization. The eigenstate thermalization hypothesis …             Faraday rotation echo spectroscopy and detection of quantum fluctuations ▶     Shao-Wen Chen, Ren-Bao Liu     Central spin decoherence is useful for detecting many-body physics in environments and moreover, the spin echo control can remove the effects of static thermal fluctuations so …             Strain-induced enhancement of plasma dispersion effect and free-carrier absorption in SiGe optical modulators ▶     Younghyun Kim, Mitsuru Takenaka, Takenori Osada et al.     The plasma dispersion effect and free-carrier absorption are widely used to change refractive index and absorption coefficient in Si-based optical modulators. However, the weak …             Green preparation of reduced graphene oxide for sensing and energy storage applications ▶     Zheng Bo, Xiaorui Shuai, Shun Mao et al.     Preparation of graphene from chemical reduction of graphene oxide (GO) is recognized as one of the most promising methods for large-scale and low-cost production of graphene-based …             Unveiling the complex organization of recurrent patterns in spiking dynamical systems ▶     Andrés Aragoneses, Sandro Perrone, Taciano Sorrentino et al.     Complex systems displaying recurrent spike patterns are ubiquitous in nature. Understanding the organization of these patterns is a challenging task. Here we study experimentally …             Stable Cycling of SiO2 Nanotubes as High-Performance Anodes for Lithium-Ion Batteries ▶     Zachary Favors, Wei Wang, Hamed Hosseini Bay et al.     Herein, SiO2 nanotubes have been fabricated via a facile two step hard-template growth method and evaluated as an anode for Li-ion batteries. SiO2 nanotubes exhibit a highly …             High performance polymer solar cells with as-prepared zirconium acetylacetonate film as cathode buffer layer ▶     Zhan'ao Tan, Shusheng Li, Fuzhi Wang et al.     Low-work-function active metals are commonly used as cathode in polymer solar cells (PSCs), but sensitivity of the active metals towards moisture and oxygen results in poor …             Disorder-induced Room Temperature Ferromagnetism in Glassy Chromites ▶     C. Moyses Araujo, Sandeep Nagar, Muhammad Ramzan et al.     We report an unusual robust ferromagnetic order above room temperature upon amorphization of perovskite YCrO3 in pulsed laser deposited thin films. This is contrary to the usual …             Ultrasmall SnO2 Nanocrystals: Hot-bubbling Synthesis, Encapsulation in Carbon Layers and Applications in High Capacity Li-Ion Storage ▶     Liping Ding, Shulian He, Shiding Miao et al.     Ultrasmall SnO2 nanocrystals as anode materials for lithium-ion batteries (LIBs) have been synthesized by bubbling an oxidizing gas into hot surfactant solutions containing …             Cell death stages in single apoptotic and necrotic cells monitored by Raman microspectroscopy ▶     Eva Brauchle, Sibylle Thude, Sara Y. Brucker et al.     Although apoptosis and necrosis have distinct features, the identification and discrimination of apoptotic and necrotic cell death in vitro is challenging. Immunocytological and …             High resolution imaging beyond the acoustic diffraction limit in deep tissue via ultrasound-switchable NIR fluorescence ▶     Yanbo Pei, Ming-Yuan Wei, Bingbing Cheng et al.     Fluorescence imaging in deep tissue with high spatial resolution is highly desirable because it can provide details about tissue's structural, functional, and molecular …                     • Careers & Jobs           naturejobs.com Science jobs of the week       PhD position     Ulm University            Postdoctoral Research Fellow     Duke University            Postdoctoral Research Assistant     Queen Mary University of London            Research Fellow     The University of Warwick            Postdoctoral Fellow     Medical University of South Carolina            Research Associate     University of Leicester            Postdoctoral Research Associate     University of Liverpool            Research Assistant     University of Bristol            Postdoctoral Research Fellow     Memorial Sloan-Kettering Cancer Center          No matter what your career stage, student, postdoc or senior scientist, you will find articles on naturejobs.com to help guide you in your science career.
