[High-impact polystyrene]

Chemical Recycling of Problematic Polymeric Wastes

 
 
 
NEXT
PREV
特徴・独自性
  • The Yoshioka Laboratory works on the recycling of various polymers by thermal and wet processes. Plastics such as poly(ethylene terephthalate) (PET), polyvinyl chloride (PVC), and high impact polystyrene (HIPS) cause serious problems during their recycling for the recycling process and the environment. However, these materials can also be seen as a resource for new materials. The decarboxylation of PET results in high yields of benzene that can be used as a chemical feedstock. Another important feature is the dehalogenation of flame retarded plastics and PVC. Dechlorinated plastic waste can be an important source for hydrocarbons, which can be used as fuels and chemical feedstock. The chemical modification of PVC offers the possibility of new materials with new properties. Modified PVC can be used as antibacterial material or as a material with ion exchange properties. The removal of brominated flame retardants from HIPS leads to higher recovery rates of styrene during thermal processing. When a wet process is used, the resulting flame retardant free HIPS can be reused.
実用化イメージ

We are eager to help companies to overcome their problems during recycling and recovery, and provide solutions for the treatment of waste materials.

[high-temperature injury]

Methods to Restore Strelity of Gramineous Plants under High- and Low-Temperature Stress Conditions

NEXT
PREV
特徴・独自性
  • Plant reproductive development is more sensitive than vegetative growth to many environmental stresses. High-temperature injury is becoming an increasingly serious problem due to recent global warming. In wheat, barley, and other crops, the early phase of anther development is most susceptible to high temperature. Oppositely, grain yields in rice plants are often reduced by exposure to low temperature. Unexpected climate change, such as abnormally hot or cool summer temperatures, have occurred repeatedly during recent years. This method indicates that an appropriate use of specific phytohormones, such as auxin and GA, may promote stress tolerance and adaptation to abiotic stresses.
実用化イメージ

These potentially novel functions of the classical phytohormones will be important sustainable agriculture in the face of global climate change.

NEXT
PREV
特徴・独自性
  • The recycling rate of construction muds and sludge is very low because the water content of these muds is very high and direct reuse of them is very difficult. Therefore, a new recycling technology for high-water content sludge has been developed in this laboratory. This technology is called "Fiber-Cement-Stabilized Soil Method", and it uses fiber materials and cement. The main feature of this method is to mix the fiber materials with the sludge, and the fiber materials included in the soil produce several geotechnical merits.
実用化イメージ

The modified soils produced by this method can be used as ground materials for reinforced embankment of the river bank and soil structures because they have several features such as high failure strength, high failure strain high durability for drying and wetting and high dynamic strength.

[Histone modifications]

Testing sperm samples from fathers can predict the incidence of autism spectrum disorder in their children

 
NEXT
PREV
概要

Autism spectrum markers:
Measuring histone modifications in sperm may be able to predict the risk of neurodevelopmental disorders in the next generation.

従来技術との比較

It is known that the highest risks with regard to the development of developmental disorders in children are ageing and premature birth in both parents, and it has been repeatedly epidemiologically reported that the risk is higher in ageing fathers than in ageing mothers among the parents. Conventionally, sperm are only examined under a microscope to check sperm count, morphology and motility, but not at the molecular level. The present invention is an innovative method that focuses on epigenetic molecular markers.

特徴・独自性
  • While birthrates are falling rapidly, developmental disorders are on the rise
  • Focus on plastic epigenetic molecules as a successional effect of paternal ageing.
  • Sperm testing can be performed non-invasively.
  • Suitable as a quality check for sperm donors etc.
実用化イメージ

特徴・独自性
  • Treatment with hot-compressed or subcritical water is an attractive process for converting food waste into valuable materials. Water is an environmentally acceptable solvent and is cost effective; thus, hot-compressed water has recently received attention as a medium for resource recovery from waste. We chose fish gelatin as a model of marine food waste (especially fish skin fraction), and we determined the optimum conditions for the degradation of fish gelatin with hot-compressed water between 160 and 240 °C at 2 MPa. These conditions were optimized in terms of maximizing the concentrations of specific degradation products, such as peptides, and ACE inhibitory.
実用化イメージ

The disposal of fish waste has become a serious problem in marine food industries because approximately half of the fish mass, including the skin, bones, entrails, and some meat. The feasibility of converting organic waste by hot-compressed water (subcritical water treatment) into useful resources has been demonstrated together with Industry.

[Hybrid nanomaterials]

Supercritical Hydrothermal Synthesis of Organic-Inorganic Hybrid Nanoparticles

 
 
 
NEXT
PREV
特徴・独自性
  • We invented supercritical hydrothermal synthesis method for the synthesis of organic modified nanoparticles (NPs). Under the supercritical state, the organic molecules and metal salt aqueous solutions are miscible and water molecule works as an acid/base catalyst for the reactions. Organic-inorganic conjugate NPs can be synthesized under this condition. This hybrid NPs show high affinity with the organic solvent or the polymer matrix, which leads to fabricate the organic inorganic hybrid nanomaterials with the trade-off function (super hybird nanomaterials). These hybrid materials of polymer and ceramics fabricated with NPs achieve both high thermal conductivity and easy thin film flexible fabrication, namely trade-off function.
実用化イメージ

For example, by the surface modification of BN particles by supercritical method, affinity of BN and polymers could be improved, so that high BN content of hybrid materials, thus high thermal conductivity materials, could be synthesized. Also by dispersing high refractive index NPs like TiO2 or ZrO2 into polymers transparently, we can tune the refractive index of the polymers. CeO2 nanoparticles are expected to be used for high performance catalysts. To transfer those supercritical fluid nano technologies, a consortium was launched with more than 70 companies.

特徴・独自性
  • Hybrid materials that show multi-functions of polymer and nanoparticles are expected to be used in future industries, and thus many research and development have been actively conducted. However, since the affinity of polymer and inorganic nanoparticles is very low, in most of the cases, properties of different materials are incompatible in the hybrid materials. To create the hybrid materials with incompatible multi-functions has been considered a difficult task.
  • However, by using supercritical fluid technology, we have succeeded in making hybrid materials with incompatible multi-functions.

Now, variety of hybrid materials are being developed, including
・Transparent, flexible, high reflective index, and high fabricability,
・Flexible, high heat conductivity, low electric resistivity, and high fabricability.

[Hydraulic fracturing]

Development of the method of Baby Borehole Hydraulic Fracturing, BABHY

特徴・独自性
  • For the effective measurement of the reopening pressure in hydraulic fracturing, it is necessary to use the testing equipment with sufficiently small compliance. This limitation makes it difficult to apply the hydraulic fracturing for the measurement of the maximum stress, because the compliance of conventional equipments is generally so large. Taking account of this situation, we proposed a new concept which allows us to do the in-situ tests of hydraulic fracturing for stress measurement at so deep depths as more than 1 km. We call the concept the Baby Borehole Hydrofracturing, BABHY for short. In order to put the new concept into practice, we developed the BABHY sonde and finally we succeeded to carry out hydraulic fracturing test by using the tools in a vertical borehole of 811 m depth. We hope to conduct collaborative research with a willing company for a practical application of this technology in industry.
