Ultrathin Organic Material Enhances E-skin Display 

From University of Tokyo (Japan), April 18, 2016: 
 
"University of Tokyo researchers have developed an ultrathin, ultraflexible, protective layer and demonstrated its use by creating an air-stable, organic light-emitting diode (OLED) display. This technology will enable creation of electronic skin (e-skin) displays of blood oxygen level, e-skin heart rate sensors for athletes and many other applications.

The research group at the University of Tokyo's Graduate School of Engineering has developed a high-quality protective film less than two micrometers thick that enables the production of ultrathin, ultraflexible, high performance wearable electronic displays and other devices. The group developed the protective film by alternating layers of inorganic (Silicon Oxynitride) and organic (Parylene) material. The protective film prevented passage of oxygen and water vapor in the air, extending device lifetimes from the few hours seen in prior research to several days. In addition, the research group was able to attach transparent indium tin oxide (ITO) electrodes to an ultrathin substrate without damaging it, making the e-skin display possible."

Self-Healing, Flexible Electronic Material Restores Functions After Many Breaks

From Penn State University,
May 16, 2016, by Liam Jackson:
 
 
"Electronic materials have been a major stumbling block for the advance of flexible electronics because existing materials do not function well after breaking and healing. A new electronic material created by an international team, however, can heal all its functions automatically even after breaking multiple times. This material could improve the durability of wearable electronics.

The material that the Penn State team created restores all properties needed for use as a dielectric in wearable electronics - mechanical strength, breakdown strength to protect against surges, electrical resistivity, thermal conductivity and dielectric, or insulating, properties. Most self-healable materials are soft or "gum-like" but the material researchers created is very tough in comparison."

Multifunctional Core-Shell and Nano-Channel Design for Nano-Sized Thermosensor

From NASA Tech Briefs,
March 31, 2016, by Defense Treat Reduction Agency (Ft. Belvoir, VA):
 
"Effective temperature sensing is important for many military-related activities, including environmental sensing in a highly explosive event. Researchers at Rensselaer Polytechnic Institute and Texas State University are developing novel nano-sized thermal sensors based on a multifunctional core/shell and nano-channel design that can be used to measure temperature and retaining thermal history of the biological agents experienced during the testing of agent-defeat weapons.

Au-based nanostructure in thin film geometry was explored as potential nano-sized dynamic thermal sensors. The Au ultrathin films with different thicknesses varying from 1 to 5 nm were prepared by thermal vaporation on silica substrates."

Thin-Film Solar Cells: How Defects Appear and Disappear in CIGSe-Cells

From Helmholtz Zentrum Berlin (Germany), April 21, 2016:
 
"Copper-indium-gallium-selenide (CIGSe) solar cells have the highest efficiency of polycrystalline thin-film solar cells. The four elements comprising CIGSe are vapour-deposited onto a substrate together to form a very thin layer of tiny chalcopyrite crystals. It is an exceedingly complex process controlled by many variables. This is why CIGSe modules in standard industrial formats have not yet attained the record efficiency already demonstrated at laboratory scale. One possible cause: defects that reduce the efficiency level can form during the course of fabrication.

A collaboration of German, Israeli, and British teams at Helmholtz Zentrum Berlin has now conducted detailed studies of how different fabrication techniques influence the microstructure. They were able for the first time to observe the defects as these formed during deposition and under what conditions they self-healed by using in-situ X-ray diffraction and fluorescence analysis capabilities at the BESSY II X-ray source."

All-Transparent Photoelectric Devices Using Metal Oxides

From SPIE Newsroom,
April 20, 2016, by Joondong Kim
et al. 
(DOI: 10.1117/2.1201604.006406):
 
"Researchers at Incheon National University (Republic of Korea) have developed a highly transparent nickel oxide/zinc oxide (NiO/ZnO) functional device for UV detection, which has around 90% transparency and strong protection against UV exposure. Moreover, the wide bandgap material combination actively absorbs UV, making the material a strong candidate for UV photodetection in flame detection or missile defense strategies.

They have produced a new class of all-metal oxide transparent photoelectric devices (T-PEDs) from the NiO/ZnO junction. The team developed nickel oxide for the p-type transparent layer, and zinc oxide for the n-type layer. They formed this heterojunction p-NiO/n-ZnO using widely available large-scale sputtering. Their device has no opaque metal electrode, enabling full transparency (visible light permission >80%)."

NRL Reveals Novel Uniform Coating Process for p-ALD

From US Naval Research Laboratory (NRL), April 20, 2016: 
 
"Scientists at the U.S. Naval Research Laboratory (NRL) have devised a clever combination of materials - when used during the thin-film growth process - to reveal that particle atomic layer deposition, or p-ALD, deposits a uniform nanometer-thick shell on core particles regardless of core size, a discovery having significant impacts for many applications since most large scale powder production techniques form powder batches that are made up of a range of particles sizes.

The work suggests that water, a reactant in the ALD process, is reason for the same rate of growth on different particles. This uniformity of thickness on different particle sizes in a particular batch is determined to be due to the difficulty of removing residual water molecules from the powder during the purging cycle of the ALD process."

Clearing the Way for Real-World Applications of Superhydrophobic Surfaces

From Aalto University (Finland), April 8, 2016: 
 
"Researchers at Aalto University call for standardized testing of superhydrophobic materials. Agreeing on a unified testing method is needed to allow community-wide comparison between published results. This would significantly progress development of superhydrophobic materials and their transfer to commercial products in, for instance, self-cleaning and anti-icing applications.

Currently, research groups around the world use many different kinds of tests to evaluate the durability and wear of superhydrophobic materials. For example, researchers have used linear abrasion, circular abrasion, sandblasting and water jets in testing the surfaces. However, the results obtained through different methods are not comparable, which makes it hard to find the best materials for applications."

A Flexible Camera: A Radically Different Approach to Imaging

From Columbia University, April 13, 2016, 
by Holly Evarts:
 
"A team at Columbia University, Engineering, has developed a novel sheet camera that can be wrapped around everyday objects to capture images that cannot be taken with one or more conventional cameras. The new "flex-cam" requires two technologies-a flexible detector array and a thin optical system that can project a high quality image on the array. They designed and fabricated a flexible lens array that adapts its optical properties when the sheet camera is bent."

Massive Trove of Battery and Molecule Data Released to Public

From Lawrence Berkeley National Laboratory, June 8, 2016,
by Julie Chao:
 
"The Materials Project, a Google-like database of material properties aimed at accelerating innovation, has released an enormous trove of data to the public, giving scientists working on fuel cells, photovoltaics, thermoelectrics, and a host of other advanced materials a powerful tool to explore new research avenues. But it has become a particularly important resource for researchers working on batteries. Co-founded and directed by Lawrence Berkeley National Laboratory (Berkeley Lab) scientist Kristin Persson, the Materials Project uses supercomputers to calculate the properties of materials based on first-principles quantum-mechanical frameworks. It was launched in 2011 by the U.S. Department of Energy's (DOE) Office of Science.

Two sets of data were released last month: nearly 1,500 compounds investigated for multivalent intercalation electrodes and more than 21,000 organic molecules relevant for batteries and liquid electrolytes as well as a host of other research applications. The recent release includes two new web apps-the Molecules Explorer and the Redox Flow Battery Dashboard-plus an add-on to the Battery Explorer web app enabling researchers to work with other ions in addition to lithium."

Generation of "Tailored" Magnetic Materials

From University of Geneva (Switzerland),
April 11, 2016:
 
"Researchers at the University of Geneva (UNIGE), Switzerland, in collaboration with French and English teams, have succeeded in manipulating the magnetic properties of two oxides which can be either ferromagnetic or antiferromagnetic; that is, with or without net magnetic moment.

They combined two materials, LaNiO3, a metallic paramagnet (without magnetic order), and LaMnO3, an insulating antiferromagnet, by alternating a layer of the first, then of the second, etc. The properties of the interfaces depended on the number of layers stacked. Measurements of the physical properties revealed that the properties of LaNiO3 are very different when in contact with LaMnO3. From being a metal without magnetic order, it becomes not only magnetic but also insulating. Moreover, the overall properties of the artificial material depend on the individual thickness of the layer of each material and they can also change as a function of the chosen thickness. This research is not limited to magnetic materials, but it is also of interest for materials that are simultaneously magnetic and ferroelectric."

Electrons Slide Through the Hourglass on Surface of Bizarre Material

News, written by Catherine Zandonella, provided courtesy of Princeton University Office of Communications, April 13, 2016:
 
"A team of researchers at Princeton University has predicted the existence of a new state of matter in which current flows only through a set of surface channels that resemble an hourglass. These channels are created through the action of a newly theorized particle, dubbed the "hourglass fermion," which arises due to a special property of the material. The tuning of this property can sequentially create and destroy the hourglass fermions, suggesting a range of potential applications such as efficient transistor switching.

The researchers theorize the existence of these hourglass fermions in crystals made of potassium and mercury combined with antimony, arsenic or bismuth. The crystals are insulators in their interiors and on their top and bottom surfaces, but perfect conductors on two of their sides where the fermions create hourglass-shaped channels that enable electrons to flow."

PolyU Develops Perovskite-Silicon Tandem Solar Cells with the World's Highest Power Conversion Efficiency

From Hong Kong Polytechnic University, April 12, 2016
 
"The Hong Kong Polytechnic University (PolyU) has successfully developed perovskite-silicon tandem solar cells with the world's highest power conversion efficiency of 25.5% recently. The research team in the Department of Electronic and Information Engineering made this world record with innovative method to enhance energy conversion efficiency.

PolyU's research team maximized efficiency with three innovative approaches. Firstly, the team discovered a chemical process - low-temperature annealing process in dry oxygen to reduce the impact made by perovskite defects. Secondly, the team fabricated a tri-layer of molybdenum trioxide / gold / molybdenum trioxide with optimized thickness of each layer, making it highly transparent for light to go into the bottom silicon layer under perovskite layer. Finally, by mimicking the surface morphology of the rose petals, a haze film, developed by PolyU Institute of Textiles and Clothing, has been applied as the top layer of the solar panel to trap more light"
