A Significiant Scientific Breakthrough : The World’s Largest Photonic Crystal


A team led by the distinguished professor Lin Tsung-Hsien from the Department of Photonics invested in the research of a three-dimensional photonic crystal with a single-crystal structure. Through bilateral cooperation between Taiwan and the Unite State, they successfully produced the world's largest single-crystal three-dimensional photonic crystal in two years and demonstrated its excellent photoelectric characteristics. The outstanding research and development results were presented in the top international journal Nature Communications and have prompted the development of  three-dimensional liquid photonic crystals ranging from tens to thousands of mircometers. Such an increase in hundredfold signifies a breakthrough in the limitations of traditional artificial photonic crystals, and indicates that the research can be used in the future to effectively control microscopic three-dimensional laser, femtosecond ultrafast pulse modulation, and vatious photonic elements.


The first Manned Submersible in Taiwan


Taiwan Ocean Research Institute of the National Applied Research Laboratories, National Defense University, the Jong Shyn Shipbuilding Group,  the CSBC Corporation Taiwan, Metal Industries Research & Development Center, and NSYSU cooperated and jointly announced their investment in the research and development of the first manned submersible constructed in Taiwan and their partnership in cultivating talent in relevant industrial fields. Through the cooperation of the industry, academia, and research, the six major units have collaborated to form the Manned Submersible Development Alliance, which plans to construct a manned underwater vehicle (submersible) within five years for scientific and technological research, and actively cultivate relevant talents. This is expected to accelerate the progress of ongoing marine green-energy projects in Taiwan, including offshore wind power, Kuroshio power plants, and deep ocean water as well as support military joint training, military survey, and underwater rescue.

New Sludge Reduction Technology Original Electric Dehydration System Designed at NSYSU


Professor Yang Chin-Chung of the institute of Enviromental Engineering proposed a processing method different from the conventional pressure filtration approach and pioneered the use of electric power-assisted pressure filtration, naming it as an "electric dehydration system" for short. This novel system successfully combines two types of plate filter press (plate and frame filter press and recessed plate filter press) and can be applied to organic sludge dehydration. The novel electric dehydration system can significantly reduce the water content of organic sludge to 60%-65%, sludge cake volume by 30%-45%, and content of plasticizer and some pollutants in sludge cake. Therefore, this approach can lower the cost of sludge treatment by approximately half and alleviate the problem of landfill space, thereby constituting a sludge reuse and environmental protection. 

Customized Spinal Cord 3D Printing with Lastest Bone Materials


An additive manufacturing project was commissioned by the MOST to the following: Chair Professor Jacob Chih-ching Huang of the Department of Materials and Optoelectronic Science, Professor Che-Hsin Lin and Cheng-Tang Pan of the Department of Mechanical and Electro-Mechanical Engineering, Professor Jason Shian-Ching Jang of the Institute of Materials Science and Engineering of National Central University, Associate Professor Hsuan-Kai Lin of National Pingtung University of Science and technology, and Associate Professor Chung-Hwan Chen of the Department of Orthopaedics of Kaohsiung Municipal Ta-Tung Hospital, and his team at the Department of Orthopaedics, Kaohsiung Medical Univesity. After two years of work, they have successfully developed the first customizable replacement cancellous bone made of metallic glass through 3D printing. Patients will benefit from this locally desighed and manufactured product that not only substantially reduces the cost of lumbar surgery but also enhances the durabilitiy of the replacement bone.

Flexible OLED: Roll Up Your Mobile devices and carry them in your pocket


Portable devices seen in movies, such as paper-thin flexible mobile phones and rolls of plastic film which can be transformed into televisions, may not exist only in the realm of sceience fiction in the future. Associate Professor Mei-ying Chang and Professor Wen-yao Huang of the Department of Photonics invented three materials that are critical in developing flexible organic light-emitting diode components. The three meterials comprise flexible universal planes for display and electronic applications; flexible, transparent, conducting thin films; and deep-blue polymer light-emitting meterials. This development may enhance the portability of photoelectric devices such as televisions and mobile phones.

Portable Radars Guarantee Dairy Quality


Professor Tzyy-Sheng Hong of the Department of Electrical Engineering spent 6 years developing portable raders, garnering the interest of an American dairy system developer. The two parties signed a licensing contract worth US$2 million and an additional 3% royalty from annual global sales, which became the largest technology transfer in the history of the Taiwanese information and communications industry. This innovation can remotely and precisely detect the physiological conditions of animals and detect the presence of abnormalities. Because the portable raders detect the heartbeat, pulse, and breath, the physiological conditions of animals can be consistently monitored, enabling effective control of the quality of animal products by preventing infected meat and dairy from entering into the market.
