Development of Novel material contributing to Environmental Purification using Natural Energy

October 16, 2012 · Filed Under Clean Tech · Comments Off on Development of Novel material contributing to Environmental Purification using Natural Energy 

Showa Titanium Co., Ltd., subsidiary of Showa Denko (SDK) has announced the development of titanium oxide fine particles for use in UV-light-responsive photo catalyst with high level of activity. When exposed to UV light titanium oxides causes strong oxidation /reduction reaction helping to decompose stains from organic substances. It also exhibits ultra hydrophilicity causing water to spread as a thin film, making the titanium oxide based photo catalyst an ideal product for environmental purification using only natural energy in such applications as antifogging window glass and antifouling coating for external walls.

Showa Denko K.K. (SDK) has announced the production of bio-based biodegradable polyester resin Bionolle™ using bio-derived succinic acid. The new Bionolle can be completely decomposed after use into water and carbon dioxide, where it has been used in compost bags as well as mulch films. Read more

Introducing the Carbon-Coated Aluminum Foils for Lithium Ion Battery by SDK

January 26, 2011 · Filed Under Green Tech · 9 Comments 

Showa Denko K.K. (SDK) and Showa Denko Packaging Co (SPA) has announced the volume production of carbon-coated aluminum foils capable of reducing electrical resistance of lithium-ion battery (LIB) electrodes, resulting in substantial improvement in quick charge/discharge performance, a requirement for collectors in automotive LIBs. The new aluminum foils with the trade name of SDX ™ can reduce the contact resistance by around 50% in comparison with conventional plain aluminum foils. SDX has been manufactured through coating plain aluminum foils with electrically conductive carbon, using company’s proprietary technology. Read more

Thermoelectric Power Generation Based on Waste Heat

February 3, 2010 · Filed Under Clean Tech, Green Tech · Comments Off on Thermoelectric Power Generation Based on Waste Heat 

SDK thermoelectric power generation moduleConversion of heat energy into electricity is based on electric potential difference which is caused by temperature differences at both sides of thermoelectric elements. Around 70% of total energy provided in Japan is wasted through its emission into the atmosphere, making thermoelectric power generation a viable method for utilization of this vast untapped energy coming form different sources, including incinerators, automobiles, ships and industrial equipment, while at the same time it will contribute in reduction of CO2 emission. Up to now, development of thermoelectric power generation has been done on the low temperature range between 100 to 300 degrees Celsius involving hot springs and diesel engines. Based on this, Showa Denko (SDK) and Plantec have made an announcement on full scale demonstration of thermoelectric power generation based on waste heat using SDK thermoelectric conversion modules in a waste incinerator built by Plantec.

Shipment of 2.5- inch Hard disk Media by Showa Denko

September 9, 2009 · Filed Under Trendy Products · Comments Off on Shipment of 2.5- inch Hard disk Media by Showa Denko 

Showa Denko made an announcement on shipment of 2.5-inch size hard disk media with storage capacity of 334GB utilizing the fifth generation perpendicular magnetic recording (PMR) technology. SDK has already commercialized the 1.89, 2.5 and 3.5-inch fourth generation PMR media storage. Showa Denko claims that this is the largest capacity for this size of hard disk in the industry (i.e. the world) but I don’t believe this is the case based on earlier announcement by Toshiba on development of 2.5 inch HDD with the storage capacity of 640GB.

Development of new technology in production of Carbon separators for PEFCs by SDK

July 23, 2009 · Filed Under Green Tech, Trendy Products · Comments Off on Development of new technology in production of Carbon separators for PEFCs by SDK 

Showa Denko K.K has developed a Bipolar-type Carbon separator for PEFC capable of increasing ouput density of polymer electrolyte fuel cells (PEFCs). Lowe cost and lighter weight of the newly developed separator has been achieved through substantial changes in the process and raw materials by SDK. This has resulted in 30% increase in output density compared to PEFCs previously developed by SDK. Read more

Development of New Polymer Electrolyte Fuel Cell Catalysts by SDK

July 23, 2009 · Filed Under Green Tech, Trendy Products · 1 Comment 

Polymer Electrolyte Fuel Cell (PEFC) catalysts are used both for anode as well as cathode to encourage chemical reactions of hydrogen and oxygen. Although platinum is currently being used as catalyst, platinum high cost plus its low level of reserves around the world restricting the spread of PEFCs. In addition to these, platinum-based catalyst faces possible melting problem when it is used at a point close to cathode. In view of this shortcoming, Showa Denko K.K. (SDK) has developed an alternative substance to platinum as a PEFC catalyst. The new catalyst is comprised of niobium-oxide-based catalyst and a titanium-oxide-based catalyst, each containing carbon and nitrogen atoms resulting in a highest achieved efficiency in terms of open circuit voltage and durability in comparison to other alternative platinum substitute catalysts in the world according to the company.
