Ammonia mono-fuel combustion 04/12/2016

Gas Turbine Power Generation with a Methane-Ammonia Gas Mixture and 100 % Ammonia– Ammonia as a hydrogen carrier to fuel power plants –

AIST has achieved 41.8 kW of gas turbine power generation using ammonia as fuel, in collaboration with Tohoku University. Ammonia has been attracting attention as a hydrogen carrier with high hydrogen content, and is promising as a fuel for power generation. The researchers were able to achieve gas turbine power generation using a methane and ammonia gas mixture, demonstrating the possibility of power generation by ammonia bifuel combustion in large-scale thermal power plants that use natural gas as fuel. They also succeeded in generating power by 100 % ammonia combustion, which could lead to large-scale CO2-free power generation.

Symbiont acquisition mechanism 10/30/2015

Elucidation of the Unique Mechanism for Symbiont Acquisition in Stink Bugs, a Group of Notorious Pest Insect
– Stink bugs screen symbiotic bacteria inside the gut –

AIST, in collaboration with Hokkaido University, the Open University of Japan, National Institute for Agro-Environmental Science, and Pusan National University, has shown that stink bugs, known as agricultural pests, select only a specific symbiotic bacterium among various bacteria ingested with food by the narrow segment developing in their gastrointestinal tract, and take the bacterium into their symbiotic organ. The present results have elucidated a unique mechanism involved in acquiring specific symbiotic bacteria, which is a characteristic shared by diverse stink bugs, and are expected to lead to the development of a new method for controlling pest insects by inhibiting the establishment of gut symbiosis.

Lyrics animations 01/25/2016

Publication of a Service That Allows Easy Production and Sharing of Videos with Lyrics Animated in Synchrony with Music- Anyone can enjoy creating lyrics animation that matches their style with “TextAlive” –

AIST has developed the lyrics animation production support service “TextAlive” (http://textalive.jp/?lang=en) which enables users to animate lyrics in time with music, using song and lyrics contents published on the web. By choosing a song and specifying the video’s style, users can quickly produce lyrics animations with various effects. In addition, users can choose “templates” of visual effects for each word or character with an intuitive interface. Furthermore, users can program templates and their parameter tuning interfaces, then share the templates with other users on TextAlive. Using TextAlive, thus, allows people to demonstrate their creativity and enjoy lyrics animation production without an enormous effort.

Terahertz modulation of light 02/12/2016

Terahertz Modulation of UV Light by Graphene Nano-ribbon
–Simulating the feasibility of a terahertz radiation device–

Terahertz modulation of UV light by a graphene nano-ribbon was theoretically presented from computational simulation. This simulation shows that the intensity of UV light passing through a graphene nano-ribbon is modulated with the frequency of terahertz. When such modulated UV light shines on a photo-conducting semiconductor, the semiconductor generates a photo-current whose intensity is modulated with a terahertz frequency. Therefore, such a photo-conducting semiconductor connected to an antenna is expected to be a source of terahertz radiation. This idea might lead to the production of compact terahertz-radiation devices which are useful for identification of organic compounds as well as observation of living matter.

Printed wiring 04/20/2016

Development of a New Principle Printing Technique That Allows Easy, High-speed, and Large-area Manufacturing of Ultrafine Electronic Circuits
– The new technology will accelerate conversion of our entire life scene environed by IoT and touch sensors –

AIST has developed an epoch-making new printing technology for metal wiring called "SuPR-NaP (Surface Photo-Reactive Nanometal Printing) technique", in collaboration with the University of Tokyo, Yamagata University, and Tanaka Kikinzoku Kogyo K.K. The developed technique utilizes selective chemisorption phenomenon of silver nanoparticles, included in silver nanometal ink, on a surface activated by ultraviolet irradiation, which is followed by the self-fusion reaction between nanoparticles to afford low-resistance silver wiring. Ultrafine electronic circuits can be produced over a large-area substrate with minimum linewidth of 0.8 μm and the circuits strongly adhere to the plastic substrates. A flexible touch-screen sensor produced by this technology is now planned to be in practical use.

Geological Survey of Japan 04/01/2015

Understanding and living with the Earth

Geological information is essential for a country like Japan, located at a tectonically active area, to ensure a safe and secure society. The Geological Survey of Japan gathers, compiles, and provides geological information and promotes its wider use. We also develop technologies to overcome various difficulties related to global environment protection, exploration of minerals and energy resources, and natural disaster mitigation, and coordinate international cooperation as a national representative.

Standard LED 04/14/2016

First Development of the Standard LED Covering the Full Visible Light - Toward evaluating next-generation lighting with higher accuracy -

AIST and Nichia Corporation have developed a standard LED having sufficient light intensity over the full visible light by introducing multiple LED dies with different central wavelengths in combination with multiple fluorescent substances. Solid-state lighting (SSL), such as LED and OLED lighting, is becoming more common as the next generation lighting. To evaluate SSL, accurate spectral measurement is indispensable. However, there has not been any standard light source covering the full visible light that suitable for measurement of SSL. By using the developed standard LED, LED manufacturers and developers will be able to evaluate SSL more accurately, which is expected to help accelerate product development and enhance performance.
