Nature Communications: Laser source for biosensors
In the area of nano photonics, scientists for the first time succeeded in integrating a laser with an organic gain medium on a silicon photonic chip. This approach is of enormous potential for low-cost biosensors that might be used for near-patient diagnosis once and without any sterilization expenditure similar to today's strips for measuring blood sugar. The researchers now present the new laser in Nature Communications: DOI: 10.1038/ncomms10864

Physicists build engine consisting of one atom
An article in the latest edition of the journal Science describes an innovative form of heat engine that operates using only one single atom. The engine is the result of experiments undertaken by the QUANTUM work group at the Institute of Physics of Johannes Gutenberg University Mainz (JGU) in collaboration with theoretical physicists of Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU).

Science Advances
'Odd couple' monolayer semiconductors align to advance optoelectronics
In a study led by Oak Ridge National Laboratory, scientists synthesized a stack of atomically thin monolayers of two lattice-mismatched semiconductors. Where the two semiconductor layers met, they formed an atomically sharp heterostructure, which generated a photovoltaic response by separating electron-hole pairs that were generated by light. The achievement of creating this atomically thin solar cell shows the promise of synthesizing mismatched layers to enable new families of functional two-dimensional materials.

WiFi capacity doubled at less than half the size
Columbia Engineering Professor Harish Krishnaswamy has integrated a non-reciprocal circulator and a full-duplex radio on a nanoscale silicon chip for the first time. This breakthrough technology needs only one antenna, thus enabling an even smaller overall system than one he developed last year: 'This technology could revolutionize the field of telecommunications,' he says.

Nanoscrolls created from graphene's imperfect cousin
Seeking an alternative, a team from MIT and Harvard University is looking to graphene oxide -- graphene's much cheaper, imperfect form. Graphene oxide is graphene that is also covered with oxygen and hydrogen groups. The material is essentially what graphene becomes if it's left to sit out in open air. The team fabricated nanoscrolls made from graphene oxide flakes and was able to control the dimensions of each nanoscroll, using both low- and high-frequency ultrasonic techniques.

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.

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.
