This review highlights the recent research advances in active nanostructured anode materials for next generation of Li-ion batteries (LIBs). In fact, order to address both energy and power demands secondary LIBs future storage applications, it is required development innovative kinds electrodes. Nanostructured based on carbon, metal/semiconductor, metal oxides phosphides/nitrides/sulfides show a variety admirable properties applications such as high surface area, low diffusion distance,...
Self-propelling bacteria are a dream of nano-technology. These unicellular organisms not just capable living and reproducing, but they can swim very efficiently, sense the environment look for food, all packaged in body measuring few microns. Before such perfect machines could be artificially assembled, researchers beginning to explore new ways harness as propelling units micro-devices. Proposed strategies require careful task aligning binding bacterial cells on synthetic surfaces order have...

Here we demonstrate substantial resonance frequency tuning in photonic metamaterial hybridized an electrically/optically switchable chalcogenide glass. The transition between amorphous and crystalline forms about 10% shift the near-infrared wavelength of asymmetric split-ring array, providing transmission modulation functionality contrast ratio 4:1 device sub-wavelength thickness.
Plasmonic nanostar-dimers, decoupled from the substrate, have been fabricated by combining electron-beam lithography and reactive-ion etching techniques. The 3D architecture, sharp tips of nanostars sub-10 nm gap size promote formation giant electric-field in highly localized hot-spots. single/few molecule detection capability nanostar-dimers has demonstrated Surface-Enhanced Raman Scattering. As a service to our authors readers, this journal provides supporting information supplied authors....
Abstract The direct conversion of light into work allows the driving micron-sized motors in a contactless, controllable and continuous way. Light-to-work can involve either transfer optical momentum or indirect opto-thermal effects. Both strategies have been implemented using different coupling mechanisms. However, resulting efficiencies are always very low, high power densities, generally obtained by focused laser beams, required. Here we show that microfabricated gears, sitting on...

So far, access intracellular environment has been obtained via spontaneous poration, electroporation, or by surface functionalization micro/nanostructures; however, these methods still suffer from some limitations due their intrinsic characteristics that limit widespread use. Here, we demonstrate...
Surface-enhanced Raman spectroscopy (SERS) sensing of DNA sequences by plasmonic nanopores could pave a way to new generation single-molecule sequencing platforms. The SERS discrimination single bases depends critically on the time that strand resides within hot spot. However, molecules flow through so rapidly signals collected are not sufficient for analysis. In this work, we report an approach control reside in spot physically adsorbing them onto gold nanoparticle and then trapping...

Top-down fabrication of electron-beam lithography (EBL)-defined metallic nanostructures is a successful route to obtain extremely high electromagnetic field enhancement via plasmonic effects in well-defined regions. To this aim, various geometries have been introduced such as disks, triangles, dimers, rings, self-similar lenses, and more. In particular, dimers are highly efficient for surface-enhanced Raman spectroscopy (SERS), their decoupling from the substrate three-dimensional design has...
