The indoor photocatalytic coating agent was applied to the wall surface, and after 8 hours under fluorescent light, the test results showed a dramatic reduction of Staphylococcus aureus from 1 million to less than 10. Additionally, under visible light irradiation, the photocatalytic activity of 'Dr. OHNO' reduced the infectivity of viruses, and a decrease in aldehydes and the generation of carbon dioxide were confirmed. Due to its high performance in antibacterial, antiviral, and odor removal, it is used as a construction option by major condominium companies, applied to general office equipment, and implemented in hospitals, livestock facilities, and nursing care facilities. Furthermore, it has been applied to the distillation pots of major whiskey distilleries. 【Performance】 ■ Bacterial removal performance ■ Virus removal performance ■ Chemical substance and harmful VOC removal performance ■ Mold removal performance *For more details, please refer to the PDF document or feel free to contact us.

A research team led by Professor Yokono has developed a "visible light-responsive titanium oxide nanomaterial" that performs highly even under weak indoor lighting. The "visible light-responsive titanium oxide nanomaterial" was tested for its ability to decompose chemical substances (such as acetaldehyde, a cause of sick house syndrome) using indoor light, and it showed approximately four times the decomposition performance compared to commonly used nitrogen-doped titanium oxide. Additionally, in the product development utilizing the "visible light-responsive titanium oxide nanomaterial," a filter with excellent antibacterial, antiviral, and deodorizing properties has been developed, and the photocatalyst has been applied to aluminum mesh filters using a thermal spraying method. *For more details, please refer to the PDF document or feel free to contact us.*

In the development of indoor high-performance titanium dioxide, there was a significant issue that needed to be resolved. The oxidation and reduction reactions (opposite reactions) were occurring simultaneously on the surface of the photocatalyst, leading to a substantial decrease in performance due to the reverse reaction. Furthermore, the photocatalytic effect could only be activated by ultraviolet light, rendering it ineffective under indoor lighting. In response, a research team led by Professor Yokono began developing next-generation titanium dioxide materials that can exhibit photocatalytic functions under indoor light (such as LED light sources) that contains no ultraviolet rays. They developed "visible light-responsive titanium dioxide nanomaterials" that perform highly efficiently even under weak indoor lighting. *For more details, please refer to the PDF document or feel free to contact us.*

Our company handles the next-generation photocatalytic coating spray 'Dr.OHNO'. Conventional UV-responsive titanium dioxide has issues such as "insufficient UV light indoors leading to a lack of photocatalytic activity" and "destruction of the coating resin." 'Dr.OHNO' has taken five years to solve these problems using two strengths: "visible light-responsive titanium dioxide" and "special resin." The special resin used is a unique soft resin that stretches three times its length, ensuring that it will not peel off unless washed or wiped. Additionally, the photocatalytic spray maintains its effectiveness as long as there is light, so once it is sprayed cleanly, the effect lasts unless wiped off. *For more details, please refer to the PDF document or feel free to contact us.

Photocatalytic paint is a white liquid that turns into a white powder when dry, and if left as it is, it will flake off and its effectiveness will not last long. Therefore, alongside the performance of the photocatalyst, the performance of the adhesive (binder) that prevents it from coming off is also extremely important. There are only three types of effective binders in the world, which are silica binder, titanium peroxide, and the special resin used in 'Dr. OHNO', utilizing the highest quality performance of "special resin." Hard materials also do not last long. The special resin used is a unique resin that is soft and stretches three times its length, and by using this, it will not peel off unless washed or wiped. *For more details, please refer to the PDF materials or feel free to contact us.

Our company handles the next-generation photocatalytic coating spray 'Dr.OHNO'. Regular alcohol disinfectant sprays only work while in use, as they evaporate or decompose, leading to a lack of lasting effectiveness and allowing new viruses to adhere. The "photocatalytic spray" maintains its effectiveness as long as there is light, so once it is sprayed clean, its effects last unless wiped away. In other words, while regular alcohol disinfectant sprays have immediate effects, they are consumables and ultimately incur costs. *For more details, please refer to the PDF document or feel free to contact us.

"Photocatalysts" are materials that decompose organic substances when exposed to light, exhibiting effects such as anti-fouling, deodorization, and antibacterial properties. When titanium dioxide is exposed to light (ultraviolet), electrons (e-) and holes (h+) are generated. These electrons and holes react with oxygen and water in the air, producing reactive oxygen species such as superoxide anion (O2-) and hydroxyl radicals (·OH) on the surface of titanium dioxide. These reactive oxygen species possess strong oxidative power, removing and decomposing organic substances, thereby demonstrating anti-fouling, deodorization, and antibacterial effects. As a material that exhibits photocatalytic effects, titanium dioxide, which is chemically stable, has been widely used as a white pigment for a long time and is also a safe substance used in cosmetics and pharmaceuticals as a bulking and molding agent. *For more details, please refer to the PDF document or feel free to contact us.

The negative impacts of global warming include an increase in extreme weather events such as the intensification of typhoons, along with a rise in associated disasters, deforestation, and desertification. On Easter Island, famous for its Moai statues, excessive deforestation occurred as the population grew, driven by the need for firewood for heating, fishing canoes, and transporting Moai statues. As a result, the island faced severe food shortages, leading to frequent conflicts between tribes and ultimately the collapse of their civilization. Now, what happened on Easter Island is about to occur on a global scale. Even if the goals of our global warming countermeasures differ, we can share the outcomes towards those goals. The actions of individuals and companies for their respective warming countermeasures are the beginning of everything. [Negative impacts of global warming] - Increase in extreme weather events such as the intensification of typhoons and the associated rise in disasters - Effects on agriculture and fisheries due to rising temperatures - Flooding and submersion of islands due to rising sea levels - Progression of deforestation and desertification - Increase in ultraviolet radiation due to the expansion of the ozone hole, etc. *For more details, please refer to the external link page or feel free to contact us.
