    The surface modification of LEDs based on GaAs is realized by super-aligned multiwalled carbon nanotube (SACNT) networks as etching masks. The surface morphology of SACNT networks is transferred to the GaAs. It is found that the light output power of LEDs based on GaAs with a nanostructured surface morphology is greatly enhanced with the electrical power unchanged.

  2. Rapid Low-Temperature 3D Integration of Silicon Nanowires on Flexible Substrates

    A rapid low-temperature transfer bonding method is developed to fabricate 3D nano-architectures suitable for application in flexible electronics. High frequency vibration is used to achieve the transfer bonding within a few seconds, resulting in a polymer-matrix-free vertical integration of SiNWs on a graphene/PET substrate. This 3D integration creates a mechanically robust and electrically Ohmic contact.

  3. Bioinspired High-Performance Energetic Materials Using Heme-Containing Crystals

    Synthetic hemozoin crystals (β-hematin) are assembled with aluminium nanoparticles (nAl) to create a nanomaterial composite that is highly energetic and reactive. The results here demonstrate that hemozoin rapidly oxidizes the nAl fuel to release large amounts of energy (+12.5 ± 2.4 kJ g−1).

    Composites: Oxidative Intercalation for Monometallic Ni2+-Ni3+ Layered Double Hydroxide and Enhanced Capacitance in Exfoliated Nanosheets (Small 17/2015) (page 1986)

    Ni(OH)2 unilamellar nanosheets are stranded in carbon nanotube (CNT) networks with the formation of 3D nanosheet/CNT composites. On page 2044, superior capacitive behavior of the unilamellar nanosheets is achieved by P. S. Lee and co-workers due to complete interfacial charge storage arising from the confined Faradaic reactions at the interfacial region and the interconnected conductive network. The restacking of active nanosheets during electrochemical cycling is effectively prohibited.

    Inspired by nature, X.-Y. Yang, G. Tian, B.-L. Su, and co-workers develop a novel interfacing encapsulation approach for cell-surface functionalization. On page 2003, individual cyanobacterium cells are interfaced with nanoporous biohybrid layers within the mesoporous silica layers. The biointerface acts as an egg membrane for cell protection and growth of the outer shell. The resulting bilayer shell efficiently creates a single-cell photosynthetic bioreactor with high stability, reusability, and activity.
