Chinese ID Card Production Center open day

chinese id card

According to the Beijing Daily, yesterday is Beijing ID Card Production Center open day. The police of the Beijing Municipal Public Security Bureau showed the public into the resident identity card making workshop, and decrypted the resident ID card “birth” process.

The city’s all identity cards are issued by this small workshop with 12 staffs, the finished ID cards will be sorted, and then sent to the 19 branches of the household registration management department, and finally delivered to the hands of residents. At the peak days, the shop will be able to make 60,000 second-generation ID card.

According to the introduction, whole system certification process will involve the entry of personal information which is linked with the personal privacy of residents, and thus it requires a high degree of security and confidentiality. Usually out only department head and 12 workshop staffs and technical personnel are allowed to enter the shop. In order not to affect the accreditation system, no camera and phones are allowed in the shop.

In January of this year, Beijing with Yanshan and Yizhuang as the first batch of pilot units, has started the ID card fingerprint registration. Before the end of this year, the city’s all household registration police stations will start the fingerprint information registration. “In the future, one may need to enter the fingerprint information in the bank counter to prevent fraudulent use.” one policeman introduced to the public.

Binhai Power Supply Company has recently accepted the first application of the resident “power generation” to be connected into the power network, as well as accepted the first individual electricity selling business. Currently, residents of the Binhai New Area can sell electricity at a temporary price of 0.4118 yuan per kilowatt hour (kWh), slightly higher than the price offered by the power plant electricity.

It is understood that the resident has installed a self-generating equipment in their own space, which had been approved by the electricity sector. At present, the Zhongxing Tianjin Eco-City has China’s first smart grid demonstration system, it shows that personal electricity grid has better adaptability to the national grid by using the smart grid system. With the promotion of smart grid, personal power and the network is expected to be achievable in the more areas.

In accordance with the relevant policies, the residents are paid to use the self-generation equipment to supply electricity to the national power grid in order to promote energy generation by utilising the local advantages such as windy weather. Self-generating power which is 10 kV or below voltage can be connected to the national grid, and individual outlets should not exceed the total installed capacity of 6 MW. Equipment may be based on various types of energy such as solar, natural gas, biomass, wind energy and geothermal energy.

In the future, individuals or companies who want to supply electricity to the national grid through self-generation equipment must apply for approval. At the same time, the applicant needs to have agreement of the owners’ committee and the adjacent residence owners.

Record of the world’s lightest material refreshed in China

Professor Gao Chao from Zhejiang University managed to make an ultra-light airgel which refreshes the current record of the world’s lightest material with flexible and oil-absorbing abilities. This material is also called as “full carbon airgel” with solid material density of 0.16 milligrams per cubic centimeter which is only 1/6 of the air density. This progress is also recently reported in the Nature magazine.

Background:

lightest material

In 1931, using silica the U.S. scientists made the earliest Aerogel with the nickname “frozen smoke”. In 2011, American HRL Laboratories, University of California, Irvine, and the California Institute of Technology in cooperation made a nickel airgel with density of 0.9 mg / cubic centimeter refreshing the lightest material record at that time. The photo showing the airgel floating over the flower was named the year’s top ten pictures of the “Nature” magazine impressed Gao. “Can a material be created to break this record?”, this idea surrounded Gao’s mind.

Updated development:

Currently, the lab is focusing on the research on adsorption properties of this material. The researchers said, the “carbon sponge” may be the ideal material to be used in insulation, energy storage, catalyst support, oil and sound-absorbing materials, as well as efficient composite.
