The 7th China Harbin International Scientific an¶↕d technological achievements exhibition fair ↑ and the third 45 ° north latitud✔' e Innovation Forum (hereinaft© er referred to as "Harbin Science and T€&<echnology Association") was ≤☆λheld in Harbin from October 12 to 1λ ★→4, 2018.
This year's Harbin Scien↕Ω→✔ce and Technology Association f₽♠ocuses on cross-border and cross regi♣¶ ₽onal scientific and technological cooperation, fo→<™£cusing on new materials, bα♦≈ioengineering and new medicine♠, cold industry and other field's. Organize Russia, South Korea, Iran ★π÷and other countries and regions, as well as ☆Ω&>domestic innovation subjects to p•€σarticipate in the meeting. As of the ←α9th, 1061 scientific and technological proje<§→£cts from 30 countries and r®♦ ∞egions, including Russia, Ukraine, Belarus↕φ, the United Kingdom, Iran § ±and South Korea, have been co↔α✔llected. 92 technical requ≠÷♣βirements projects have been collected, φ∞and 47 projects have achieved pre docking. T©αhe organizing committee confirmed that 102 groupΩδ≈←s, 515 units and 1007 projects from 10 ≠γ≤foreign countries and regions≈$≤, 15 domestic cities and Harbin ci☆≈"ty participated in the exhibit≥σion.
At the Harbin Science and technology confere$λ>nce, Shenzhen Photonics Valley Technolo↑$gy Co., Ltd. demonstrated the ultra fast mobile©€ power supply and optical tweezers sysγ♣tem. At present, the mobile power supply has >♦€the disadvantages of long char←ging time and slow charging for mobile ph¶€÷↕ones. The ultra fast mobile power sup↓ ±βply developed by Shenzhen Op ↕ ≠tical Valley Technology Co., Ltd.•∞★★ provides fast, energy-saving and porta×®εble solutions. At the same time, it ha<≥s outstanding heat dissipation and r∞÷♦₽eliable performance. It has aroused g≥φ®reat interest of professionals inβ∏ the same industry and is willing to cooperat™αe and purchase products.
At the same time, Shenzhen Photonics©σ Valley Technology Co., Ltd. also conducted £&§ a demonstration of optical•↑✔ tweezers system. The product optical twee "zers use the three-dimensional optical potenti↑βal well generated by laser to confine the sma¥δΩll particles meeting the relativ₩₽"e refractive index in the poσγtential field, and capture and± move the particles by the transα<✘fer of photon momentum. Theβ™ optical tweezers adopts 63↑™ π8nm semiconductor laser, and the t↓₩est sample is 3 μ m polystyrene'≥γ microsphere. It can be used for real-tim'↑>e tracking operation in computer, mobile phone a♣↑nd other terminals through step-controll©&εβed motor, which can be used for t§¶₩≠eaching demonstration and other applications✘ ÷β.
