Researchers create artificial materials atom-by-atom
Researchers at Aalto University have manufactured artificial materials with engineered electronic properties. By moving individual atoms under their microscope, the scientists were able to create atomic lattices with a predetermined electrical response. The possibility to precisely arrange the atoms on a sample bring 'designer quantum materials' one step closer to reality. By arranging atoms in a lattice, it becomes possible to engineer the electronic properties of the material through the atomic structure.

Rare-earths become water-repellent only as they age
Surfaces that have been coated with rare earth oxides develop water-repelling properties only after contact with air. Even at room temperature, chemical reactions begin with hydrocarbons in the air. In the journal Scientific Reports, researchers from the University of Basel, the Swiss Nanoscience Institute and the Paul Scherrer Institute report that it is these reactions that are responsible for the hydrophobic effect.

Chemists created nanoparticles for safe imaging of tumors
Chemists from Russia and Switzerland created biosafe luminescent nanoparticles for imaging tumors and blood vessels damaged by heart attack or stroke. The particles are made of hafnium oxide that is allowed for intravenous injection, and doped with ions of rare earth metals. The scientists hope that the development will give an alternative to toxic quantum dots and help imaging deep tissues without harming a human body. The study appeared in Colloids and Surfaces B: Biointerfaces.

Spintronic technology advances with newly designed magnetic tunnel junctions
Magnetic tunnel junctions (MTJs) have played a central role in spintronic devices, and researchers are working to improve their performance. A prominent achievement that accelerated the technology's practical applications was the realization of giant tunnel magnetoresistance (TMR) ratios by using rock-salt type MgO crystalline barrier. In this week's Applied Physics Letters, researchers have succeeded in applying MgGa2O4 to a tunnel barrier, the core part of an MTJ, as an alternative material to more conventional insulators.

Manipulating magnetic textures
While the ability to easily control the magnetic properties of small electronic systems is highly desirable for future small electronics and data storage, an effective solution has proven to be extremely elusive. But now, a group of researchers from universities in Chile and Brazil are reporting this week in the Journal of Applied Physics, a simple way to gain control of magnetism that starts by controlling the shape of the systems.

Unexpected, star-spangled find may lead to advanced electronics
In a recent study, University of Texas at Dallas researchers describe a material that, when heated to about 450 degrees Celsius, transforms from an atomically thin, two-dimensional sheet into an array of one-dimensional nanowires, each just a few atoms wide. An image caught in mid-transformation looks like a tiny United States flag, and with false colors added, is arguably the world's smallest image of Old Glory, researchers said.

'Flying saucer' quantum dots hold secret to brighter, better lasers
By carefully controlling the size of the quantum dots, the researchers can 'tune' the frequency, or color, of the emitted light to any desired value. The ability to produce a laser of any desired frequency from a single material would give a boost to scientists looking to study diseases at the level of tissues or individual cells by offering new tools to probe biochemical reactions. They could also enable laser display projectors that would be brighter and more energy efficient than current LCD technology.

Nano-polycrystalline film leads to stronger magnetism compared to single-crystal films
Toyohashi University of Technology researchers have found that nanoscale pillar-shaped distribution of iron in strontium titanate changes its magnetic and magnetooptical response drastically in cooperation with researchers at Myongji University, Harbin Institute of Technology, Massachusetts Institute of Technology, Universidad Técnica Federico Santa María, University of California, San Diego, and Trinity College Dublin. Surprisingly, the polycrystalline film on the silicon substrate showed stronger magnetism than a single crystalline film.

The repulsion trick: A self-solving puzzle for organic molecules
Jülich researchers have succeeded in controlling the growth of organic molecules using a special trick. Due to their opposing forces, molecules that repel each other always keep a certain distance from their neighbors. Therefore, they mix easily with a second, mutually attracting type of molecule that acts as a sort of 'glue.' Tailored surface structures can thus be put together like pieces in a puzzle -- in a seemingly self-solving manner.
