Supercool electrons

27-Jan-2017

The future of quantum computing is a hot topic not only for experts but also in many commercial and governmental agencies. Rather than processing and storing information as bits in transistors or memories, which limit information to the binary '1' or '0', quantum computers would instead use ...

Sensor sensation

27-Dec-2016

Microfluidic platforms have revolutionized medical diagnostics in recent years. Instead of sending blood or urine samples off to a laboratory for analysis, doctors can test a single drop of a patient's blood or urine for various diseases at point-of-care without the need for expensive ...

Lights, action, electrons!

12-Oct-2016

Ever since J.J. Thompson's 1897 discovery of the electron, scientists have attempted to describe the subatomic particle's motion using a variety of different means. Electrons are far too small and fast to be seen, even with the help of a light microscope. This has made measuring an electron's ...

The next generation of carbon monoxide nanosensors

27-May-2016

The detection of carbon monoxide (CO) in the air is a vital issue, as CO is a poisonous gas and an environmental pollutant. CO typically derives from the incomplete combustion of carbon-based fuels, such as cooking gas and gasoline; it has no odour, taste, or colour and hence it is difficult to ...

Confirming the link between disorder and metastability in granular physics

23-May-2016

There is an important difference between knowing something, and being able to prove something. Even in science, there are ideas that everyone shares, but no one can prove. The link between disorder and metastability in a s was one of such ideas, until three researchers devised an experiment to ...

New ways to construct contactless magnetic gears

18-Feb-2016

The new milk frother you are using to prepare your cappuccino is likely using magnetic gears. Magnetic gears transmit rotary motion like mechanical gears but instead of teeth they use magnetic attraction and repulsion between rotating magnets. Dr Johannes Schoenke, a postdoctoral scholar at the ...

Shaping crystals with the flow

16-Feb-2016

One of goals of the Okinawa Institute of Science and Technology Graduate University (OIST) is to foster collaboration between different disciplines. Recently, OIST scientists combined techniques from soft matter physics and structural biology to create and visualise crystals made of surfactants, ...

Visualizing atoms of perovskite crystals

12-Jan-2016

Organic-inorganic perovskite materials are key components of the new generation of solar cells. Understanding properties of these materials is important for improving lifetime and quality of solar cells. Researchers from the Energy Materials and Surface Sciences (EMSS) Unit, led by Prof. Yabing ...

Using atoms to turn optical nanofiber guided light on and off

10-Dec-2015

Researchers in the Light-Matter Interactions Unit led by Professor Síle Nic Chormaic at the Okinawa Institute of Science and Technology Graduate University (OIST) have developed an on-off switch with ultrathin optical fibers, which could be used for data transfer in the future. OIST researchers ...

Silver: The promising electrode winner for low-cost perovskite solar cells

16-Oct-2015

Perovskite solar cells are the rising star in photovoltaics. They absorb light across almost all visible wavelengths, they have exceptional power conversion efficiencies exceeding 20% in the lab, and they are relatively easy to fabricate. So, why are perovskite solar cells yet to be found on the ...
