Environmental Science: Nano
Magnetized viruses attack harmful bacteria
Antibacterial phages combined with magnetic nanoparticle clusters effectively kill infectious bacteria found in water treatment systems. A weak magnetic field draws the clusters into biofilms that protect the bacteria and break them up so the phages can reach them.

Applied Physics Letters
Ferroelectric phenomenon proven viable for oxide electrodes, disproving predictions
Flux-closure domain structures are microscopic topological phenomena found in ferroelectric thin films that feature distinct electric polarization properties. These closed-loop domains have garnered attention among researchers studying new ferroelectric devices, and in the development of thin films for such devices, researchers have thought that contact with commonly used oxide electrodes limits FCD formation. However, a group of researchers in China has shown otherwise. They report their work in this week's Applied Physics Letters.

Scientists discover new magnet with nearly massless charge carriers
Advances in modern electronics has demanded the requisite hardware, transistors, to be smaller in each new iteration. Recent progress in nanotechnology has reduced the size of silicon transistors down to the order of 10 nanometers. However, for such small transistors, other physical effects set in, which limit their functionality. The recent discoveries of topological materials -- a new class of relativistic quantum materials -- hold great promise for use in energy saving electronics.

Broadband light sources with liquid core
Research scientists from Jena were successful in producing broadband laser light in the mid-infrared range with the help of liquid-filled optical fibers. With these fibers, they also provided experimental proof of a new dynamics of hybrid solitons -- a new type of temporally and spectrally stationary light waves resulting from the unique characteristics of the liquid core.

On-chip pumps achieve high-speed sorting of large cells
Nagoya University research developed a high-speed cell sorting method of large cells with high-viability using dual on-chip pumps. The microfluidic chip has three-branched microchannels. Target cells are sorted into one of two interest channels by the high-speed flow produced by the on-chip pumps, while non-target cells enter a waste channel without pump actuation. The technique overcomes the limitation of many on-chip cell sorting methods in achieving the sorting of large cells at a high throughput.

Ultracold molecules hold promise for quantum computing
A study by MIT researchers shows that collections of ultracold molecules can retain the information stored in them for hundreds of times longer than previously achieved in these materials. These clusters might thus serve as 'qubits,' the basic building blocks of quantum computers.

High-speed FM-AFM and simulation reveal atomistic dissolution processes of calcite in water
We have developed high-speed frequency modulation AFM (FM-AFM) and enabled atomic-resolution imaging in liquid at ~1 s/frame. With this AFM, we have obtained images revealing the transition region is formed along the step edges. Our simulations suggest the transition region be a Ca(OH)2 monolayer formed as an intermediate state. Thus, our understanding of the calcite dissolution in water is much improved. This FM-AFM will be applicable to various studies on solid-liquid interface dynamic processes.

Fundamental breakthrough in the future of designing materials
A team of researchers from Trinity College Dublin have made a breakthrough in the area of material design -- one that challenges the commonly held view on how the fundamental building blocks of matter come together. They have shown that the granular building blocks in copper can never fit together perfectly, but are rotated causing an unexpected level of surface roughness. This behavior, previously undetected, will have important implications for how materials are designed.

Novel thermal ablation system for transdermal drug delivery
The size of protein-based drug molecules prevents their absorption into the body when taken orally making injection (intramuscularly, subcutaneously, intravenously, etc.) the only effective delivery method. Research into transdermal drug delivery systems to make taking these drugs easier and cheaper has lead Japanese researchers to develop a new photothermal abrasion system. It uses near-infrared light to irradiate gold nanorods in a gel skin patch to increase skin temperature and permeability for improved drug delivery.

Atomic discovery opens door to greener, faster, smaller electronic circuitry
A key step in unlocking the potential for greener, faster, smaller electronic circuitry was taken recently by a group of researchers led by UAlberta physicist Robert Wolkow. The research team found a way to delete and replace out-of-place atoms that had been preventing new revolutionary circuitry designs from working. This unleashes a new kind of silicon chips for used in common electronic products, such as our phones and computers.
