Will Apple be Next Nokia?

On July 7, Counterpoint Technology, a market research institute, released its research about smart phone market share of May. It showed that Apple only accounts for 10.8%, which is 1.2% decrease compared with May, 2015 and fell to fifth. On the contrast, China domestic smart phones, the four largest brands, Huawei, Vivo, Oppo and Xiaomi, have been increasing and the percentage is 53%. Among the data, Huawei ranked first with 17.3%, and Oppo 11% with a double going up.

Time goes back. In April, Apple released last quarter financial report. iPhone sales volume had declined as the first time in its sales history. So is its revenue, which is going down 13%, and 33% compared with the first quarter in 2015. After that, Apple promotes its iPhone SE with lower value of USD500.00, in order to interest the small screen users. No doubt, this type of iPhone has been the most obscure products of Apple these years. With a respect, it may run into the rural market. However, it may still lose with the competition of Vivo and Oppo. Even Citibank has lowered down its expectation of the third and fourth quarter financial report, and predicts that iPhone change time will last 30 to 36 months.

tungsten crucible and sapphire screen

After those not so good reports of Apple, will it be next Nokia? It may and may not. If iPhone can effectively grasp the chance of phone change time and increase its quality, including its broken sapphire screen, which is growing in tungsten crucible in thermal field, then it may change its unfavorable situation. Surely, China domestic brands are also improving their quality better and better, so that their competition ability will be stronger. In order to increase their screen quality, the crucible should be pure enough, which is over 99.95%, for assurance of the quality of sapphire. Chinatungsten has been producing tungsten crucible over 20 years, its purity and quality can meet the requirement of producing out high-quality sapphire. Then it could be a power to support the hard ware parts of phones.

What’s more, South Korea experts agreed with our counterparts domestic enterprises in the rare earth standard.

The delegations also intuitively understood that the stuff and equipments situation of two countries for international standardization rare earth, which enhanced the confidence of international standardization work. The success of the exchange creates a good start to promote wolfram heater and other rare international standardization work. Moreover, China also learned advanced production technology from the two countries in this visit, which would help to improve the productivity and quality of the tungsten heater.

Defect-Rich Tungsten Trioxide Nanosheet Photocatalyst

Recently, Professor Xiong Yujie of University of Science and Technology of China (USTC), and his group cooperated with a number of the USTC professors to design a class of defect-rich tungsten oxide nanosheet, this kind of new photocatalytic material exhibits excellent aerobic coupled catalytic performance under broad spectrum light conditions, and is expected to achieve low power consumption and low cost of chemical production. It is reported that the defect-rich tungsten trioxide nanosheets have precisely controllable oxygen vacancies, and promote the efficient transfer of photogenerated electrons from the oxide catalyst to oxygen molecules; at the same time, the emergence of defect states significantly broaden the photocatalyst absorbance range to capture solar energy in the wide spectral range of visible and near infrared region. The achievement of Professor Xiong Yujie group achieved effectively capture and conversion of solar energy to pass to solve the bottleneck problem in the oxide catalyst photocatalytic organic synthesis, and make the possibility for the use of solar energy replacing thermal in organic synthesis.
defect-rich tungsten trioxide
Metal oxide (tungsten trioxide ect.) has the advantages of low cost, and exhibits a photocatalytic activity, which is a class of ideal catalytic materials. The key step of semiconductor photocatalysis is in the photocatalyst excitation, the migration of photo-generated electrons and holes, the recombination of electrons and holes in the catalyst or on the surface. Low quantum efficiency of photocatalytic reaction is the most critical factor which makes the photocatalyst difficult to practical use. The core of Professor Xiong yuJie group developed defect-rich tungsten trioxide photocatalyst nanosheet lies in how to reduce cost of catalyst material and improve the efficiency of energy conversion.
 
At present, doping or semiconductor composite is usually used to reduce costs and to improve catalytic efficiency of tungsten trioxide photocatalyst, such as tungsten trioxide as a carrier after loading the precious metals (e.g. Pt, Au, etc.), it will show strong oxidizing in the presence of water and oxygen thus to help organic synthesis with high reactivity; titanium dioxide and tungsten trioxide complex semiconductor to improve the photocatalytic activity.

 

WO3 Catalytic Fuel Cell Vehicle Eases Global Warming

Hydrogen fuel cells for its comprehensive advantages of zero-emission, high energy density and conversion rate, long battery life and short time refueling hydrogen ect., is considered to be one of the "best path" for the development of new energy vehicles. With restrictions FCV (Fuel Cell Vehicle) development bottlenecks continue to be resolved, the international leader in the fuel cell technology company's products have been sent to the commercial promotion levels; in the case of cost, over the past 10 years, the production costs of fuel cell system has plummeted with also a certain decline space left; about the support facilities, governments have stepped up efforts to support hydrogen refueling station to relieve the problem in the operation of fuel cell.

fuel cell vehicle
 
The operating principle of hydrogen fuel cell vehicles is that the hydrogen is sent to the fuel cell anode plate (anode), an electron in the hydrogen atom is separated out through the effect of catalyst; then hydrogen ions (protons) which lose electrons will pass through the proton exchange membrane to arrive at the fuel cell cathode plate (positive electrode), while the electron can not pass through the proton exchange membrane, only through an external circuit to reach the cathode plate of the fuel cell, thereby generating a current in the external circuit. After the electrons reach the cathode plate, they will recombine with the hydrogen ions and oxygen atoms to water. Since oxygen supplied to the cathode plate can be obtained from the air, as long as continue to supply hydrogen to the anode plate and the air to the cathode plate with timely water (steam) away, electricity will be continue to be provided. Theoretically, hydrogen fuel cells emit only water, not carbon dioxide, sulfur dioxide, nitrogen dioxide and other products of and the fossil fuels, thus to ease the global warming and improve air quality.
 
The study found that WO3 has a strong corrosion resistance, does not react with almost any acid without the hydrofluoric acid, which is particularly suitable for the high humidity, acidic environment of fuel cell. In addition, the conventional Pt catalyst belongs to precious metal, the addition of WO3 can not only reduce the cost of the catalyst; at the same time, since the WO3 and the metal will produce synergistic catalytic effect which improves the efficiency of the catalyst; in addition, WO3 has the corrosion resistant, as a partial substitute carrier C to longer the life of the catalyst, and also indirectly improve the catalytic efficiency.

 

"Made In China 2025" Promotes the Development of Tungsten Heater

As the first decade guideline of "three-step" strategy for construction of manufacturing power of China, "Made In China 2025" depicts a path for Chinese manufacturing from large to strong, which has been gained high-level attention by Communist Party of China (CPC). In early July 2015, the State Council set up national manufacturing power construction leading group, and the vice-premier Ma Kai is the group leader, and there are more than 20 government departments involved in this group. This group has held the third meeting and established a consultative committee for construction strategy of national manufacturing power, and builds up intersectoral links joint-action mechanism and actively mobilizes multi-power and enthusiasm.

Over the past year, for the implementation of the "Made in China 2025", the government mainly carried out three aspects. Firstly, the government prepared and issued the "1 + X" plan. Secondly, the government formulated a number of supporting policies. CBRC revised the "Commercial Bank M & A Loan Risk Management Guidelines" to encourage the support of commercial banks to manufacturing concern. It would work with the Ministry of Industry and Information Technology of the People’s Republic of China to further improve the financing guarantee system. The introduction of these supporting policies, mainly in order to provide the reasonable support for necessary innovation and development for manufacturing.

The third is to strengthen the guidance of local, promote development of regional differences. Some effects and implementation of policies and the major projects has been initially apparent. For example, “Enterprise R & D Expenses Plus Deduction Policy” further stimulates industrial enterprises, especially SMEs (Small and Medium Enterprises) innovation and dynamic development. Future development of "Made in China 2025" will be more perfect, be more conducive to long-term development of business volume, so that it will greatly facilitate the tungsten heater and other tungsten enterprises development.
