Bacterial cellulose (BC) is produced by microorganisms and is 100 to 1000 times thinner than plant-derived cellulose, with excellent biodegradability and water retention properties. This study explored methods that could lead to the mass production of materials expected to have various applications. Since the microorganisms originally do not have the ability to produce BC, it is difficult to expect sufficient production levels of BC, and the cost becomes a challenge when seeking mass production. In the method for mass production of BC derived from research results, cases were confirmed where a symbiotic relationship is established between cellulose-producing bacteria and photosynthetic microorganisms. This enables the production of BC using microorganisms that can be cultured in the field. 【Conventional Technology and Issues】 ■ Difficulties in outdoor cultivation and management ■ Since the microorganisms originally do not have the ability to produce BC, it is difficult to expect sufficient production levels of BC ■ High costs associated with seeking mass production *For more details, please refer to the PDF document or feel free to contact us.

The present invention is a chemical synthesis technology for proanthocyanidins, specifically "epigallocatechin oligomers." Proanthocyanidins, "epigallocatechin oligomers," are a type of polyphenol that is expected to have metastasis-inhibiting effects on cancer cells, and there are expectations for the development of functional foods that have never been seen before, as well as their use as reagents.

• Organic Natural Materials

Fusicoccin, a diterpene glycoside isolated as a metabolic product of fungi that parasitize trees such as almonds, has been reported to irreversibly open plant stomata and induce continuous transpiration, leading to the death of the plant. In this invention, it has been revealed that under sufficient light and water supply, fusicoccin functions as a plant growth enhancer.

Traditionally, methods for producing graphene have involved vapor-phase methods or exfoliation methods. Vapor-phase methods can produce highly crystalline graphene, but they have the challenge of high costs, while exfoliation methods are low-cost but result in graphene with low crystallinity. This technology involves a method for uniformly dispersing partially oxidized graphene with low oxygen content in a hydrophobic ionic liquid through the electrochemical exfoliation of graphite in a water-hydrophobic ionic liquid two-phase system. 【Features of the Technology】 - Two-phase system (water-hydrophobic ionic liquid) electrochemical exfoliation method - Surface oxygen concentration below 10%, eliminating the need for re-reduction treatment - Control of surface oxygen concentration is possible A wide range of materials can be applied to the graphite electrodes, and by exploring ways to reuse the ionic liquid, significant reductions in manufacturing costs are expected.

I would like to introduce "water-soluble porphyrin derivatives." Porphyrins are used in photodynamic diagnosis (PDD) and photodynamic therapy (PDT) for cancer diseases; however, porphyrins typically lack water solubility and biocompatibility, and they require time for metabolism. This technology allows for the synthesis of water-soluble porphyrin derivatives by combining porphyrins with sugar chains that exhibit excellent water solubility and biocompatibility. 【Features of the technology】 - Water solubility - Biocompatibility - Polymer derivatives (can be processed into films)

Introducing a technology for the simple and highly accurate quantification of surface charge sites in nanomaterials. Conventional surface charge site quantification techniques have faced challenges such as being time-consuming and labor-intensive, and the high cost of automatic titration devices. In this technology, the sample size is extremely small compared to titration methods, and it can be executed using only highly versatile equipment. Additionally, it allows for rapid (within 2 hours) and simple operations, achieving measurement accuracy comparable to titration methods. **Features** - The sample size is extremely small compared to titration methods (0.5 to 2.5 mg per run). - Can be executed using only highly versatile equipment (centrifuge and visible light spectrophotometer). - Allows for rapid (within 2 hours) and simple operations, achieving measurement accuracy comparable to titration methods. - Enables individual quantification of strong acidic sites (sulfuric ester groups) and weak acidic sites (carboxyl groups). - Dye adsorption is completed in 2 hours. *For more details, please refer to the PDF document or feel free to contact us.*

We will introduce the technology for directly cultivating clay nanosheets with excellent adsorption properties using silica gel. Cation exchange materials are utilized by being packed into columns or dispersed in water, but in the latter case, it is important that the adsorbent can be easily recovered. In conventional technologies, recovery through filtration or centrifugation can be difficult when dealing with fine particles (at the nanoscale). In this technology, the material hardly delaminates even in solvents that typically cause swelling and delamination, making recovery from the solution easy. Since it thinly coats the silica surface, it is useful for separation in distribution systems. 【Features】 - Hardly delaminates even in solvents that cause swelling and delamination - Easy recovery from the solution - Thinly coats the silica surface, aiding in separation in distribution systems - Not dependent on the shape of the starting silica *For more details, please refer to the PDF document or feel free to contact us.

We will introduce a translucent electrode made of photocatalytic powder and a "water-splitting tandem cell" using it. By using titania nanosheets as both an anchor and conductive layer for the powder, we have developed a novel method to create a translucent photoanode from photocatalytic powder materials. By using this translucent powder photoanode as the top cell and a powder photocathode for hydrogen generation as the bottom cell, we enable the construction of a powder material-based tandem cell capable of complete water splitting under sunlight irradiation. 【Features】 ■ Tandem structure ■ Reaction driven in a self-sustained state without wiring ■ No need for product separation ■ Steam splitting (potential use of seawater) ■ Useful energy carrier *For more details, please refer to the PDF document or feel free to contact us.
