EPJ E
Tumble-proof cargo transporter in biological cells
Ever wondered how molecular nanomotors work when transporting material such as organelles in the cell? Typically, nanomotors move along biopolymer filaments to go about their duties in the cell. In a new study published in EPJ E, Mu-Jie Huang and Raymond Kapral from the University of Toronto, Canada show that synthetic motors can attach to polymeric filaments and move along without changing either their shape or the direction in which they set out to move.

Researchers generate clean energy using bacteria-powered solar panel
For the first time ever, researchers at Binghamton University connected nine biological-solar (bio-solar) cells into a bio-solar panel. Then they continuously produced electricity from the panel and generated the most wattage of any existing small-scale bio-solar cells - 5.59 microwatts.

Quantum dots enhance light-to-current conversion in layered semiconductors
Scientists combined the excellent light-harvesting properties of quantum dots with the tunable electrical conductivity of a layered tin disulfide semiconductor to produce a hybrid material that exhibited enhanced light-harvesting and energy transfer properties. The research paves the way for using these materials in optoelectronic applications such as energy-harvesting photovoltaics, light sensors, and light emitting diodes (LEDs).

Wearable sweat sensor thanks to battery-free 'water pump' inspired by plants
Plants and trees soak up water in the soil by letting it vaporize through pores in the leaves. Scientists at Eindhoven University of Technology have now taken this principle to develop a sweat sensor through which the sweat itself flows at a steady rate, without external power, and is analyzed.

Intracellular recordings using nanotower electrodes
Toyohashi Tech researchers have developed an intracellular recording device, which has > 100-µm-long three-dimensional nanoscale-tipped microneedle-electrodes. Moreover, they demonstrated the needle penetrations into muscle cells and measured the signals. The nanoelectrode, whose size is longer than the conventional intracellular nanoelectrode (< 10-µm long), has the potential to be used in cells that are deep within a tissue, such as cells in brain slices or brain in vivo, thus accelerating the understanding of the brain.

From IT to black holes: Nano-control of light pioneers new paths
An Australian research team has achieved unparalleled levels of control over the angular momentum (AM) of light in an integrated nanophotonic chip. The work leads the way for compact on-chip AM applications like ultra-high definition display, ultra-high capacity optical communication and ultra-secure optical encryption, and could also be used to help scientists better understand the evolution and nature of black holes.

Crumpling approach enhances photodetectors' light responsivity
Researchers from the University of Illinois at Urbana-Champaign have demonstrated a new approach to modifying the light absorption and stretchability of atomically thin two-dimensional (2-D) materials by surface topographic engineering using only mechanical strain. The highly flexible system has future potential for wearable technology and integrated biomedical optical sensing technology when combined with flexible light-emitting diodes.

Magnetic delivery of therapeutic enzymes paves the way for targeted thrombosis treatment
Researchers have fabricated a new magnetically controlled material composed of enzymes entrapped directly within magnetite particles. Combined with water, it forms a stable solution that can be used for safe intravenous injection for medical purposes, in particular, for targeted treatment of cancer and thrombosis. Previously, the synthesis of similar materials involved using additional components that impaired the magnetic response and enzymatic activity as well as created obstacles for intravenous injection into the human body.

Nanoparticles can grow in cubic shape
Use of nanoparticles in many applications, e.g. for catalysis, relies on the surface area of the particles. Now scientists show how originally spherical nucleus can transform into cube with high surface-to-volume ratio. These nanocubes are available to be used in practice, and may interest many designers of new materials. The research has recently been reported in ACS Nano.

World's smallest diode, developed by U. of Georgia and Ben-Gurion U.
Dr. Dubi and his student, Elinor Zerah-Harush, constructed a theoretical model of the DNA molecule inside the electric circuit to better understand the results of the experiment. 'The model allowed us to identify the source of the diode-like feature, which originates from breaking spatial symmetry inside the DNA molecule after coralyne is inserted.'
