Toward highly accurate location estimation and channel prediction

The compressed sensing method is a method to find a solution under certain conditions from a smaller number of observation data than the number of unknowns required. In this study, we use compressed sensing for estimating the direction of arrival of radio waves, to predict the channel, and detect scatterers.

A system that collects data from a few weeks before an event to the day of the event and recommends appropriate event information.

Although event information was only valid for a short time and it was hard to handle it with conventional information recommendation technology, we have developed a flexible recommendation method by combining multiple factors such as user interest and geographic characteristics.

Both water and oil can soak well into the surface, slide off it easily, and stick to it properly

We will show you how to create superhydrophilic surfaces that can rapidly be wetted and covered in water, and superhydrophobic and superoleophobic surfaces that repel water/oil very well although their sliding behavior can easily be controlled to allow water/oil to be adsorbed on the surface or easily slide off.

New materials for the age of welfare

What kind of material should be used in an age when we are required to improve our quality of life? The answer is strong gels such as double network gels. Tough gels will help revolutionize the quality of medical devices, tissue substitutes and biomimetics.

Soft and tough composite material

By conjugating glass fiber and self-healing gel, we have achieved a gel that is stronger than carbon fiber-reinforced plastic (CFRP). Since the base material is a gel, it is as flexible as rubber against bending, but tougher than CFRP against tearing, making it difficult to break.

Evaluation of the subsurface structure necessary for geothermal resource development by gravity survey and precise determination of the seismic source. Monitoring of geothermal reservoir resources by precise gravity measurements and crustal deformation observations. Risk assessment of induced earthquakes associated with geothermal well development and research on seismic activity prediction.

New-type solar cell consisting of a multi-striped semiconductor with orthogonal photon-photocarriers that was coupled to a waveguide.

Temperature rise and device degradation are suppressed by simultaneous optimization of light absorption and photocarrier collection, as well as photoelectric conversion over the entire solar spectrum by multiple semiconductor stripes. This leads to the realization of a highly efficient 2-dimensional PhotoReceptoConversion Scheme (2DPRCS).

Submillimeter-order position measurement and its deployment

By integrating ranging technology that is more accurate than conventional methods by double digits and original time-synchronization technology using illumination, we can quickly and accurately estimate the 3D position and velocity of mobile terminals and robots. The system also realizes selective flickerless visible light communication and position-dependent information distribution to specific moving objects.

Core (alloy latent heat storage material) ? shell (Al2O3) type latent heat storage microcapsules capable of high-density heat storage in the high temperature range of over 500?C

The latent heat storage method, which utilizes latent heat generated during the solid-liquid phase change, is attractive for its high-density heat storage capacity. Microencapsulation of latent heat storage material enables not only heat storage but also heat transport and heat control applications, and we have developed latent heat storage microcapsules that can be used in the high temperature range of over 500°C.

Selective synthesis of cis-alkenes and amines

cis-Alkenes and amines, which are useful as raw materials for pharmaceuticals, agricultural chemicals and other chemical products, can be synthesized efficiently through hydrogenation of alkynes, organic nitro compounds and azides. The originally developed homogeneous palladium nanoparticles can be stored in solution for longer than a year and are easy to handle in air.

Non-invasive visualization of genetic mutations in tumors by metabolic MRI

The outcome of cancer treatment largely depends on the type of genetic mutation that the cancer cells carry. Using the characteristic metabolic changes brought about by genetic mutations as an indicator, we are developing a molecular imaging technique to identify mutated genes non-invasively using the latest metabolic MRI.

Balancing world-class functional delivery of nucleic acids and safety

We have developed a unique group of functional lipids for the safe and efficient in vivo delivery of siRNA. The lipid nanoparticles containing these lipids showed world-class functional delivery of siRNA in hepatocytes due to their excellent endosomal escape ability and high safety due to their biodegradability.

Development of materials and devices that manipulate mid- to far-infrared radiation

It is expected that it will be possible to make devices to control corresponding electromagnetic waves by creating heaters and diffraction gratings with patterns smaller than the mid- to far-infrared wavelengths. We are developing methods to fabricate thin films, stacks, and microstructures of metal carbides and oxides, and are studying their elemental characteristics.

Toward active control of the amount of liquid atomization

When ultrasonic waves are irradiated from the liquid to the liquid surface, atomization of the liquid occurs at the liquid surface. In recent years, it has become clear that microbubbles near the liquid surface are responsible for this phenomenon. We are aiming to control the amount of liquid atomization by ultrasound.

We have developed a matrix that can ionize sialylated glycans and glycoconjugates without modifying the carboxylic acid moiety of the sialic acids, and can analyze them with high sensitivity and resolution (reflector mode) without desorption of the sialic acid residue.

Bottom-up production of nanofibrillated cellulose from low molecular weight biomass using bacteria

Using biomaterials such as collagen and dental materials, we are producing micro-/nano-patterns that mimic biological structures. Depending on the shape of the pattern and the type of material, it can lead to the improvement of cell functions. While pursuing new possibilities, we aim to apply our technology to cell culture tools and periodontal tissue regeneration.
