Transporting spin: A graphene and boron nitride heterostructure creates large spin signals
Graphene Flagship scientists based at the University of Groningen, The Netherlands, have created a device based on a blilayer of graphene and boron nitride which shows unprecedented spin transport efficiency at room temperature. Highlighting the potential of creating devices containing graphene and related materials, the spin signal measured here is so large that it can be used in real life applications such as spin based logic and transistors.

Lungs in space
Houston Methodist and University of Texas Medical Branch researchers are collaborating on a study to grow lungs in space with possible implications for both astronauts and people on Earth that could lead to future therapeutics. The scientists prepared bioreactor pouches that include lung progenitor and stem cells and pieces of lung scaffolding on which the cells are expected to grow on the ISS. The experiment successfully launched aboard Space X's CRS-12 mission Aug. 14.

2-faced 2-D material is a first at Rice
Rice University materials scientists replace all the atoms on top of a three-layer, two-dimensional crystal to make a transition-metal dichalcogenide with sulfur, molybdenum and selenium. The new material has unique electronic properties that may make it a suitable catalyst.

Single molecules can work as reproducible transistors -- at room temperature
Columbia researchers published a study today in Nature Nanotechnology that is the first to reproducibly demonstrate current blockade -- the ability to switch a device from the insulating to the conducting state where charge is added and removed one electron at a time -- using atomically precise molecular clusters at room temperature. The study shows that single molecules can function as reproducible circuit elements such as transistors or diodes that can easily operate at room temperature.

Massive particles test standard quantum theory
In quantum mechanics particles can behave as waves and take many paths through an experiment. It requires only combinations of pairs of paths, rather than three or more, to determine the probability for a particle to arrive somewhere. Researchers at the universities of Vienna and Tel Aviv have addressed this question for the first time explicitly using the wave interference of large molecules behind various combinations of single, double, and triple slits.

Material-independent nanocoating antimicrobial spray extends the shelf life of produce
The research team led by Professor Insung Choi of the Department of Chemistry developed a sprayable nanocoating technique using plant-derived polyphenol that can be applied to any surface. This new nanocoating process can be completed in seconds to form nanometer-thick films, allowing for the coating of commodity goods, such as shoe insoles and fruits, in a controlled fashion.

Test uses nanotechnology to quickly diagnose Zika virus
Currently, testing for Zika requires that a blood sample be refrigerated and shipped to a medical center or laboratory, delaying diagnosis and possible treatment. Now, Washington University in St. Louis researchers have developed a test that quickly can detect the presence of Zika virus in blood. Although the new proof-of-concept technology has yet to be produced for use in medical situations, test results can be determined in minutes, and the materials do not require refrigeration.

Landscapes give latitude to 2-D material designers
Researchers at Rice University and Oak Ridge National Laboratory predict and experimentally confirm that two-dimensional materials grown onto a cone allows control over where defects appear. These defects, called grain boundaries, can be used to enhance the materials' electronic, mechanical, catalytic and optical properties.

Power-to-liquid: 200 liters of fuel from solar power and the air's carbon dioxide
Production of fuels from regenerative electric power is a component of the energy turnaround. The first 200 l of synthetic fuel have now been produced from solar energy and the air’s carbon dioxide under the SOLETAIR project by , INERATEC, a spinoff of Karlsruhe Institute of Technology (KIT), and Finnish partners. The mobile chemical pilot plant that can be used decentrally produces gasoline, diesel, and kerosene from regenerative hydrogen and carbon dioxide.

Development of molecular container with caps that can regulate uptake/release of objects
We designed a host-guest system using a non-equilibrium kinetically trapped state for on-demand and time-programmable control of molecular functions, and synthesized a macrocyclic metallohost that has anion caps at both sides of the cation-binding site. The anion caps effectively inhibit the guest uptake/release so that we can easily make a non-equilibrium kinetically trapped state. Guest exchange to a more stable state is significantly accelerated by exchange of the anion caps in an on-demand manner.

Like a game of 'spot the difference' for disease-prone versus healthy people
A specific kind of natural nanoparticles, called low-density lipoproteins (LDL), are fascinating scientists because their modification plays a key role in people affected by high cholesterol and atherosclerosis. Judith Peters from the University Grenoble Alpes and Institute Laue Langevin, Grenoble, France and colleagues recently published the results of their study in _EPJ E, showing that the LDL from healthy people behaved differently when subjected to high pressure compared to LDL affected by the common diseases studied.

New model for bimolecular reactions in nanoreactors
Theoretical physicists have devised a mathematical model of two different molecules reacting within so called nanoreactors that act as catalysts. They gained surprising new insights as to what factors promote reactions and how to control and select them. The model is relevant for a wide range of research fields, from biophysics to energy materials.

Alkaline soil, sensible sensor
Producers sometimes face challenges that go deep into the soil. They need answers to help the soil, on site. A portable field sensor can accurately measure minerals in soils more easily and efficiently than existing methods. And a research team, including a middle school student and her scientist father, can confirm it.
