OIST researchers improve perovskite-based technology in the entire energy cycle, from solar cells harnessing power to LED diodes to light the screens of future electronic devices and other lighting applications.
Researchers have developed inks made of graphene-like materials for inkjet printing. New black phosphorous inks are compatible with conventional inkjet printing techniques for optoelectronics and photonics. The inkjet printing demonstration makes possible for the first time the scalable mass fabrication of black phosphorous based photonic and optoelectronic devices with long-term stability necessary for a wide range of industrial applications.
Have your coffee without spilling the milk: researchers at Martin Luther University Halle-Wittenberg have developed a milk capsule that dissolves when placed in a hot drink. Not only does this reduce the consumption of packaging material, the capsules are easier to use than conventional plastic containers. The research group published its findings in the journal Chemical Engineering & Technology.
Chemists at ITbM, Nagoya University have developed a super-photostable fluorescent dye, PhoxBright 430 (PB430), to visualize cellular ultrastructure by super resolution microscopy. The exceptional photostability of this new dye enables continuous STED imaging and together with its ability to fluorescently label proteins, PB430 demonstrates its use in the 3D construction and multicolor imaging of biological structures.
As graphene's popularity grows as an advanced 'wonder' material, the speed and quality at which it can be manufactured will be paramount. With that in mind, the research group of SungWoo Nam, assistant professor of mechanical science and engineering at Illinois, has developed a cleaner and more environmentally friendly method to isolate graphene using carbon dioxide (CO2) in the form of carbonic acid as the electrolyte solution.
Imagine a tire that could heal after being punctured or a rubber band that never snapped. Researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have developed a new type of rubber that is as tough as natural rubber but can also self-heal.
Researchers have developed a three-layer system to verify that components produced using additive manufacturing have not been compromised by malicious activity or quality issues.
Hall thrusters are used in earth-orbiting satellites and show promise to propel robotic spacecraft long distances, and the plasma ejected from the exhaust end of the thruster can deliver great speeds. Cylindrical Hall thrusters lend themselves to miniaturization and have a smaller surface-to-volume ratio that prevents erosion of the thruster channel. Investigators in China have developed a new design for CHTs that significantly increases thrust; they report their work in this week's Physics of Plasmas.
Researchers from the University of Washington and several small companies have conducted the first large-scale experiment on a Superfund site using poplar trees fortified with a probiotic -- or natural microbe -- to clean up groundwater contaminated with trichloroethylene, or TCE.
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.
