Kenichi Honda
Kenichi Honda (本多健一, August 23, 1925 – February 26, 2011) was a Japanese chemist. He made a significant contribution to the discovery and characterization of photocatalytic properties of titanium dioxide (TiO2), for which he shared the 2004 Japan Prize with his former student Akira Fujishima. Biography In 1949 Honda received his bachelor's degree in engineering from the University of Tokyo. He then spent several years in France, where he defended a PhD in 1957 at the University of Paris. After returning to Japan he obtained a second doctorate degree, from the University of Tokyo in 1961. He then worked as a lecturer (1965–1975) and professor (1975–1983) at the University of Tokyo and at Kyoto University (1983–1989). In 1989 he moved to the Tokyo Polytechnic University and served as its president in 1996–2004. Research In the late 1960s Honda and his doctorate student Akira Fujishima discovered the Honda-Fujishima effect - photocatalytic water decomposition (phot ...

Photoelectrochemistry
Photoelectrochemistry is a subfield of study within physical chemistry concerned with the interaction of light with electrochemical systems. It is an active domain of investigation. One of the pioneers of this field of electrochemistry was the German electrochemist Heinz Gerischer. The interest in this domain is high in the context of development of renewable energy conversion and storage technology. Historical approach Photoelectrochemistry has been intensively studied in the 1970-80s because of the first peak oil crisis. Because fossil fuels are non-renewable, it is necessary to develop processes to obtain renewable resources and use clean energy. Artificial photosynthesis, photoelectrochemical water splitting and regenerative solar cells are of special interest in this context. The photovoltaic effect was discovered by Alexandre Edmond Becquerel. Heinz Gerischer, H. Tributsch, AJ. Nozik, AJ. Bard, A. Fujishima, K. Honda, PE. Laibinis, K. Rajeshwar, TJ Meyer, PV.

University Of Tokyo Alumni
A university () is an institution of higher (or tertiary) education and research which awards academic degrees in several academic disciplines. Universities typically offer both undergraduate and postgraduate programs. In the United States, the designation is reserved for colleges that have a graduate school. The word ''university'' is derived from the Latin ''universitas magistrorum et scholarium'', which roughly means "community of teachers and scholars". The first universities were created in Europe by Catholic Church monks. The University of Bologna (''Università di Bologna''), founded in 1088, is the first university in the sense of: *Being a high degree-awarding institute. *Having independence from the ecclesiastic schools, although conducted by both clergy and non-clergy. *Using the word ''universitas'' (which was coined at its foundation). *Issuing secular and non-secular degrees: grammar, rhetoric, logic, theology, canon law, notarial law.Hunt Janin: "The university i ...

Photolysis
Photodissociation, photolysis, photodecomposition, or photofragmentation is a chemical reaction in which molecules of a chemical compound are broken down by photons. It is defined as the interaction of one or more photons with one target molecule. Photodissociation is not limited to visible light. Any photon with sufficient energy can affect the chemical bonds of a chemical compound. Since a photon energy, photon's energy is inversely proportional to its wavelength, electromagnetic radiations with the energy of visible light or higher, such as ultraviolet light, x-rays, and gamma rays can induce such reactions. Photolysis in photosynthesis Photolysis is part of the light-dependent reactions, light-dependent reaction or light phase or photochemical phase or Hill reaction of photosynthesis. The general reaction of photosynthetic photolysis can be given in terms of photons as: :\ce + 2 \text \longrightarrow \ce The chemical nature of "A" depends on the type of organism. Purple su ...

Tokyo Polytechnic University
is a private university in Honchō, Nakano, Tokyo. Its nickname is ''Shadai'' (写大). It was formerly known as Tokyo College of Photography (, ''Tōkyō Shashin Daigaku''). The university was founded as Konishi Professional School of Photography in Shibuya in 1923. The founder, Rokuemon Sugiura VII, was the president of Konishi Main Shop (later Konica) at that time and founded the school to fulfil the wish of Rokuemon Sugiura VI, the previous president. Since 2007, the university has offered courses in manga studies and animation studies. Tokyo Polytechnic is also notable for being one of the few universities in Japan to have a game design department, with its faculty including such notable practitioners as Pac-Man creator Toru Iwatani and Xevious creator Masanobu Endō. The university also operates the Suginami Animation Museum, which focuses on the history and future of the animation industry in Japan.

Titanium Dioxide
Titanium dioxide, also known as titanium(IV) oxide or titania , is the inorganic compound with the chemical formula . When used as a pigment, it is called titanium white, Pigment White 6 (PW6), or CI 77891. It is a white solid that is insoluble to water, although mineral forms can appear black. As a pigment, it has a wide range of applications, including paint, sunscreen, and food coloring. When used as a food coloring, it has E number E171. World production in 2014 exceeded 9 million tonnes. It has been estimated that titanium dioxide is used in two-thirds of all pigments, and pigments based on the oxide have been valued at a price of $13.2 billion. Structure In all three of its main dioxides, titanium exhibits octahedral geometry, being bonded to six oxide anions. The oxides in turn are bonded to three Ti centers. The overall crystal structure of rutile is tetragonal in symmetry whereas anatase and brookite are orthorhombic. The oxygen substructures are all slight distort ...

Photocatalytic
In chemistry, photocatalysis is the acceleration of a photoreaction in the presence of a catalyst. In catalyzed photolysis, light is absorbed by an adsorbed substrate. In photogenerated catalysis, the photocatalytic activity depends on the ability of the catalyst to create electron–hole pairs, which generate free radicals (e.g. hydroxyl radicals: •OH) able to undergo secondary reactions. Its practical application was made possible by the discovery of water electrolysis by means of titanium dioxide (). History Early mentions (1911–1938) The earliest mention came in 1911, when German chemist Dr. Alexander Eibner integrated the concept in his research of the illumination of zinc oxide (ZnO) on the bleaching of the dark blue pigment, Prussian blue. Around this time, Bruner and Kozak published an article discussing the deterioration of oxalic acid in the presence of uranyl salts under illumination, while in 1913, Landau published an article explaining the phenomenon of ...
