COPENHAGEN Nuove Air Max Saldi , Oct. 19 (Xinhua) -- World No.2 badminton player Chen Long won the fourth gold medal for China at the men's singles final of Yonex Denmark Open on Sunday.
Chen defeated Wan Ho Son of South Korea in two straight sets 21-17, 22-20.
"Both Son and I played at our highest levels," Chen said after the match that won him 45,000 U.S. dollars as award.
Previously, top seed Li Xuerui Air Max Bambino Saldi , also of China, won the women's singles final after defeating her compatriot Wang Yihan.
The mixed doubles final at the Odense Sports Center was a clash between Chinese players Ma JinXu Chen and Indonesian Tontowi AhmadLiliyana Natsir. The Chinese duel finally triumphed with a two sets win 22-20 and 21-15.
Chinese players Wang Xiaoli and Yu Yang won the women's doubles title, beating Japanese rivals Misaki Matsutomo and Ayaka Takahashi in two sets 21-14, 21-14.
LJUBLJANA, Sept. 4 (Xinhua) -- The 12th Bled Strategic Forum (BSF) was held at Lake Bled in Slovenia on Monday to gather common international solutions to challenges posed by the changing world Air Max Bianche Saldi , including climate change and security threats.
The Forum (BSF) attracted 1,000 officials, executives and academics from some 70 countries all over the world to seek solutions to the challenges of the "new reality", according to the Slovenian Press Agency.
The host, Slovenian Foreign Minister Karl Erjavec Air Max Nere Saldi , stressed in his address that "we are facing new international actors" and "still struggle to address climate change and its negative global impact".
Slovenian Prime Minister Miro Cerar and President Borut Pahor made their speeches at the forum opening ceremony, calling for joint efforts to deal with new challenges.
The event will continue on Tuesday for its second and last day featuring the Business BSF conference and several panels, including on nuclear governance, challenges in tourism, the role of the EU in the changed world Air Max Rosa Saldi , the Western Balkans and digital diplomacy.

WASHINGTON, Aug. 24 (Xinhua) -- Chinese scientists said Thursday they have developed a super steel that has a high level of both strength and ductility Air Max 90 Saldi , a breakthrough that may have a wide variety of industrial applications.
Furthermore, its material cost is just one-fifth of that of the steel used in the current aerospace and defence applications, they reported in the U.S. journal Science.
Strength and ductility are desirable properties of metallic materials for wide-ranging applications, but increasing strength often leads to the decrease in ductility, which is known as the strength-ductility trade-off.
A Hong Kong-Beijing-Taiwan mechanical engineering team led by Huang Mingxin from the University of Hong Kong adopted a new manufacturing technique called deformed and partitioned (D&P) to addressed the problem.
"Steels have been the most widely used metallic materials in the history of mankind and can be produced with much higher efficiency than any other metallic materials Air Max 97 Saldi ," the team said in a statement.
"Therefore developing a strong and ductile breakthrough steel has been a long quest since the beginning of Iron Age in mankind history."
The team explained that it is very difficult to further improve the ductility of metallic materials when their yield strength is beyond two Gigapascal (GPa).
Now, they made "a successful attempt in realizing the above dream" as the newly developed method yields a "breakthrough steel" that has the "unprecedented" yield strength of 2.2 GPa and uniform elongation of 16 percent.
"The developed D&P steel demonstrated the best combination of yield strength and uniform elongation among all existing high-strength metallic materials," the researchers said.
"In particular, the uniform elongation of the developed D&P steel is much higher than that of metallic materials with yield strength beyond 2.0 GPa."
According to the team, the "breakthrough steel" belongs to the system of so-called medium manganese steel that contains 10 percent manganese Air Max 270 Saldi , 0.47 percent carbon, 2.0 percent aluminium and 0.7 percent vanadium.
"No expensive alloying elements have been used exhaustively but just some common alloying compositions that can be widely seen in the commercialized steels," they said.
Another advantage is that this steel can be developed using conventional industrial processing routes, including warm rolling, cold rolling and annealing.
"This is different from the development of other metallic materials where the fabrication processes involve complex routes and special equipment Air Max Vapormax Saldi , which are difficult to scale-up," said the team.
"Therefore, it is expected that the present breakthrough steel has a great potential for industrial mass production."
The research outcome was a collective contribution from scientists at the University of Hong Kong, University of Science and Technology Beijing, City University of Hong Kong Air Max TN Saldi , and a university in Taiwan.
