About Art Beam Co., Ltd. R & D Center

The activities of this center are mainly engaged in research and development of various materials and their application techniques.
The development policy aims to develop materials and techniques that enable a smooth transition to mass production and are suitable for the global environment.
Currently, there are four materials and techniques to be developed.

The first is the development of various nanoparticles.

Based on the supercritical hydrothermal synthesis method that does not require an organic solvent, we are designing, developing, and prototyping nanoparticles. Since the prototype is a continuous operation type, we will positively respond to customer requests for specific development of nanoparticles for mass production.

It is possible to answer.

The second is product development that applies conductive glass.

Taking advantage of the characteristics of conductive glass, we have commercialized a new electrode that compensates for the shortcomings of discharge electrodes in an air atmosphere, which conventional metals are not good at.

Third ... A new solar cell structure was created using new techniques and new solder materials .

This makes it possible to reduce manufacturing man-hours and electrode material costs.

Fourth: Development and trial production of a new glass frit for solar cells.

We design, develop, and prototype based on the characteristics of a wide range of glass components.

The above four product developments are currently underway independently, but in the near future we will create synergistic effects by linking these materials and techniques, which will lead to product development suitable for the coming era. Without forgetting the policy of "mass production development suitable for the global environment", we would like to continue developing materials and techniques that are loved and inherited by customers for generations.



Nanoparticle Research and Development Headquarters

Various new nanos that can be used in a wide range of fields such as electrical / electronic component materials, magnetic materials, medical materials, phosphor materials, electrode materials, catalysts, and high-refractive-index materials using the continuous supercritical hydrothermal synthesis method. We support companies that research and develop and manufacture nanoparticles and create "new functional products" with new characteristics that meet the needs of the next generation.


What is supercritical water?


What is super-critical water (SCW)?

Under atmospheric pressure, water turns into ice below 0 ° C and water vapor above 100 ° C.

Such changes in solids, liquids, and gases are called phase changes.

In the case of water, the phase change does not occur at 374 ° C and 22.1 MPa, so the conditions of this temperature and pressure are called the critical point , and the water that exceeds this critical point is called supercritical water .

The method of synthesizing nanoparticles in the region above the critical point of water is called the supercritical hydrothermal synthesis method.

The boundary between gas and liquid disappears

What is the continuous supercritical hydrothermal synthesis method?

Invented by Professor Ajiri, Distinguished Professor of Tohoku University, all the substances found on the earth are technologies with tremendous potential to be continuously synthesized as nano-sized particles. Already, the development of practical application is rapidly progressing overseas, centering on the manufacture of advanced nanomaterials.

Through the projects of Sapoin (Strategic Fundamental Technology Advancement Support Project) and NEDO (New Energy and Industrial Technology Development Organization), Tohoku University Ajiri Laboratory and this continuous supercritical hydrothermal synthesis method We have continued joint research for many years using. In addition, Super Nano Design Co., Ltd., a venture company from Tohoku University, was established with the aim of developing the business of "organic modification of inorganic materials by supercritical water reaction and synthesis of organically modified inorganic nanoparticles", which is the research result of Professor Ajiri. We are developing our business in collaboration with SND).

ABL Glass Applied Technology Development Headquarters

We are aiming to provide next-generation global environment-friendly technology by developing new electrical and electronic component materials and electrode materials based on conductive glass (ABL glass) technology and researching application techniques for products. increase.

ABL glass-  Conductive glass- 

ABL glass is a new material that conducts electricity.

ABL glass is a conductive glass mainly composed of vanadate, which was invented by Dr. Tetsuaki Nishida, the director of the Institute for Environmental Materials. We can provide it with glass frit or glass paste. The conductivity can be adjusted according to the firing conditions.

We can also make metal powder-ABL glass mixed paste according to your request.

Excellent properties of ABL glass frit

Application to discharge electrode material (e-corona electrode)

Since ABL glass is conductive glass mainly composed of vanadate, it is amorphous, oxide, and does not oxidize and does not generate rust like metal. Taking advantage of this feature, we have developed a new electrode that compensates for the shortcomings of metal discharge electrodes in an air atmosphere, which conventional metals are not good at. It is expected to be applied to electrostatic precipitators and sensor parts. Since it can be screen-printed, a wide variety of electrode structures can be formed.

Solar cell technique


Art Beam Solar Cell Technology -ABS-Technique-

ABS-Technology is an abbreviation for Art Beam Solar, which is a general term for solar cell-related technologies developed by us.

As a connection technique to realize a new solar cell structure, special solder materials and precision soldering technology make it possible to reduce manufacturing man-hours, electrode material costs, and improve electrical characteristics.

Aluminum electrode surface

Direct soldering on finger electrodes and silicon wafers

PERC type cell Direct soldering to the aluminum electrode surface

The ABS-technique allows lead wires to be connected by soldering directly to the aluminum electrode surface or silicon wafer surface, unlike traditional lead wire connections based on silver electrodes.

This makes it possible to reduce the amount of silver used and improve the electrical characteristics.
