Profile
Cellulose nanofiber materials, ISIR, Osaka University
Cellulose nanofibers with 4-20 nm width are bundles of cellulose microfibrils, which are frameworks of cell walls in all the plants. We have developed nano-fibrillation processes of bio-resources (wood, plants fibers, crabs, shrimps e.t.c.) and some advanced nanofiber materials with high optical transparency. Moreover, we have also improved their properties or processes to realize their applications in the electronic devices.

Electric Vehicle Research at Advanced Materials Osaka July 2019

Here we give the abstracts relevant to electric vehicles from BIT Advanced Materials Conference Osaka Japan July 2019. The organisers failed to provide slides but we have photographs of some of these if you are interested. The selected abstracts are divided into energy storage, wide bandgap semiconductors, energy harvesting and other.

Cancer cells distinguished neural network

In cancer patients, there can be tremendous variation in the types of cancer cells from one patient to another, even within the same disease. Identification of the particular cell types present can be very useful when choosing the treatment that would be most effective, but the methods of doing this are time-consuming and often hampered by human error and the limits of human sight.

Efficiently turning light into electricity

Perovskites form a group of crystals that have many promising properties for applications in nano-technology. However, one useful property that so far was unobserved in perovskites is so-called carrier multiplication - an effect that makes materials much more efficient in converting light into electricity.

A simple new approach to plastic solar cells

Plastic solar cells, based on blends of conducting organic polymers, are of interest for making lightweight and cheap solar cells. The problem with these kinds of solar cells is that their solar power efficiencies are very closely related to the way the different types of materials mix and crystalize in thin films. This means complex and careful processing is usually needed to make efficient polymer solar cells.

EEG headset for emotion detection

Traditionally, EEG brain scans are used to diagnose medical conditions such as epilepsy or sleep disorders. More recently, EEG brain scans have been introduced as a way to detect emotions which opens doors beyond the medical field. Researchers are looking into e-learning applications, and developers of virtual games are exploring the possibilities of emotion-based e-gaming. Such application domains require real-time emotion detection, which can be achieved through wireless EEG headsets.

Technique to allow AI to learn words in the flow of dialogue developed

A group of researchers at Osaka University has developed a new method for dialogue systems. This new method, lexical acquisition through implicit confirmation, is a method for a computer to acquire the category of an unknown word over multiple dialogues by confirming whether or not its predictions are correct in the flow of conversation.
