[bozoid 2023] Charging pile: it must be built well and be used

Tue, 31 Jan 2023 17:52:46 +0800

Currently, there is a structural contradiction between electric vehicles and new energy vehicles in our country. That is, the number of powerful batteries is sufficient in our country, but the problem is that the owners of new energy vehicles "cannot find them, they cannot use them, and they charge slowly."

Liu Yundong, Deputy Secretary General of China Electric Power Commission and Chairman of Transmission and Power Reserve Division

During this spring vacation, a car owner's bad experience of driving home in a new energy car sparked a heated debate on the Internet. According to the media, the vehicle owner originally took 15 hours for an 8-hour drive, which is one of the main reasons for the long charging standby time. "I charged the battery 3 times on the way home. I had to wait about 2 hours each time and it took another hour to charge." The owner of the car declared himself poor.

The experience of the owners of this car is no exception. With the rapid increase in the number of new energy vehicles in our country, charging has become a problem facing most car owners.

Many factors lead to "recharging of new energy vehicles".

Since the phenomenon of "charging problem" is so common, the most direct way to solve this problem seems to be to build a charging pile. But just as 'building more roads' doesn't significantly reduce traffic jams, blindly piling up chargers isn't a real solution to the charging problem.

Liu Yundong, deputy secretary-general of the China Electric Commission and head of the transmission and energy storage department, told Science and Technology Daily that there is a structural contradiction between current chargers and new energy vehicles in China. That is, the number of powerful batteries is sufficient in our country, but the problem is that the owners of new energy vehicles "cannot find them, they cannot use them, and they charge slowly."

According to statistics from the Ministry of Public Security, by the end of 2022, the number of new energy vehicles nationwide will reach 13.1 million, among which 10.45 million will be clean electric vehicles. A total of 5.21 million charging stations have been built across the country by the end of 2022, Tian Yulong, chief engineer and spokesman for the Ministry of Industry and Information Technology, told a press conference. That means, on average, every 2.5 new energy vehicles nationwide can be connected to a charging stick.

Currently, the travel needs of most new energy vehicle owners are city tours. Traveling distances in cities are typically tens of kilometers, so charging is not frequent and many charging sticks are idle.

“Currently, average social usage of charging bars in cities is less than 10%, and average social usage of charging bars on highways is much lower at less than 1%.” Tong Zongchi, Deputy General Secretary of Electric Vehicle Manufacturers and Replacement Association Branch of China Electric Vehicle Electric Infrastructure Promotion Alliance, told reporters.

Recently, on Weibo, not only the charging rod is a problem, but the problem of 'personal electric batons entering the community' is frequently searched. For example, some new communities refuse to allow new energy vehicle owners to install charging poles due to safety concerns. In some older communities, charging stations cannot be installed because they do not have permanent parking spaces and do not consider the charging needs of new energy vehicles early in planning.

[bozoid 2023] Realization of efficient synthesis of vinblastine

Tue, 31 Jan 2023 17:49:53 +0800

Recently, a reporter from Zhejiang University's Faculty of Chemical and Biomolecular Engineering and Hangzhou International Center for Science, Technology and Innovation discovered that the school's researcher Lian Jiaqiang's Research Group has used Pichia pastoris to create a new cell factory. Results related to the synthesis of the main raw material of the anti-cancer drug vinblastine are published in Nature Synthesis.

Vinblastine, which is synthesized from vinblastine and pendoline, has a very complex structure and is difficult to manufacture on a large scale and must be obtained from fresh branches and leaves. Typically, it takes over 2000 kg of dried vinca leaves to obtain 1 gram of vinblastine. Recently, with the analysis of the biosynthetic pathway of vinblastine and vindoline and the development of synthetic biology, it has become possible to gradually synthesize vinblastine from scratch.

“The synthesis of vinblastine is to buy cement, lime, tile and other decorative materials and home decorations from scratch.” Lian Jiachang introduced that the research group chose Pichia pastoris as the chassis cell and introduced various modules to synthesize Pichia pastoris. Occurs in this chassis cell. In this study, the research team created a Pichia cell factory that can efficiently synthesize vinblastine by establishing a CRISPR system, selecting a stable site, restoring cell metabolism, and optimizing the fermentation process. The biosynthetic pathway of vinblastine has been reconstructed.

Dr. Gao Zhukan, first author of the paper and Ph.D., Hangzhou International Center for Science, Technology and Innovation, Zhejiang University, said that Pichia pastoris is an unusual yeast, so it is not easy to make it into sash cells and synthesize new substances. . Model Yeast is like a simple rough house that is easy to decorate, while Unusual Yeast is like a strange house and needs to be fixed before formal decoration. Otherwise, it is difficult to add materials for synthesis.

In this study, the synthesis of complex natural products in non-model yeast not only provides new ideas for the efficient synthesis of vinblastine, but also demonstrates that Pichia cell plants can use simple carbon sources for the synthesis of alkaloids and other natural plant products. give. .

Tue, 31 Jan 2023 17:47:46 +0800

Endless green wheat plants in a field in Guanghui City, Xiangcheng City, Henan Province. At the end of 2022, Xiangcheng City agricultural technicians were very busy and came to the large wheat fields in Maolu Village, Guanghui Town early in the morning to feel the "pulse" of the village's winter wheat.

-Your land is not fertile enough, there are weeds, you can spray herbicides and foliar fertilizers to stabilize the growth of plants. good harvest... The agronomist took a handful of wheat plants and carefully examined them. Soil moisture and root system growth conditions of wheat, patiently farmer Mr. Guide Wang. Mr. Wang has handed over 460 mu of land to grow wheat, and the wheat harvest is expected next year. Despite being a local talent, we recommend agricultural technology experts to continuously improve the level of technology.

In Xiangcheng, many farmers have adopted the path of scientific agriculture, achieving rapid growth in family income, and it is the local talents in the village that lead them to prosperity. Rural talent is connected to the field on the one hand and innovation and creativity on the other hand, becoming a new driving force for rural revitalization.

In recent years, Xiangcheng City has carried out investigations, comprehensive investigations and comprehensive evaluations of various rural talents through voluntary declarations and questionnaires, and recruited "soil experts" and "Tian Xiuchai" such as cultivation experts. .« Establish folk artists and rich professionals, establish, monitor and manage talent funds and promote the role of talent.

At the same time, in order to effectively improve the qualifications and skills of workers and accelerate the transition from population allocation to talent allocation, Xiancheng City complies with Henan Province's labor requirements: "Everyone has a Henan qualified certificate", "Anyone has a qualification." Henan is an expert", regards construction as an important issue in people's lives, and guides everyone in society to actively learn about and participate in construction. in Henan", allocation "Everyone in Henan has qualifications and skills." A budget of 9.55 million yuan will be allocated in 2022 and allocated to talent training and professional development to provide financial support for talent training. .

[bozoid 2023] The road to slimming, environmental protection and upgrading of the glass industry

Tue, 31 Jan 2023 17:45:54 +0800

Hu Zhixue, deputy director of Hebei Dejin Glass Co., Ltd., is still busy during the Spring Festival when the company's new production line is about to start production.

"This production line is a float glass production line for electronics and automobiles, and is a key project for the company's product transition from architectural glass to electrical glass," said Hu Zhixue. Various contaminant discharges can reach "very low" for nitrogen oxides, for example. Hebei Province's revised ultra-low emission standard is 200mg/m3, which can be controlled within 10mg/m3.

Shahe's glass industry began when it peaked in the 1980s. Its production capacity has reached 160 million boxes, accounting for 20% of the national output. It is one of the few typical "large industrial counties" in the country, and the local economy is booming. However, it also puts tremendous pressure on the local ecological environment. Since 2013, promoting Beijing-Tianjin-Hebei air pollution control, Shahe glass industry has also experienced a "great test" of strict environmental protection.

"Only those who pass the test can survive," said Li Yanfeng, director of the Economic Development Bureau of Hebei Province's Economic Development Zone Executive Committee. Over the past decade, Sahe's glass industry has been a success. losses”, reducing the number of glass production enterprises from 176 at the time to 1.7, and reducing the number of glass production lines in production from 240 to 22. Environmental protection has also been strengthened. Invested more than 2 billion yuan to carry out ultra-low-emission transformation for glass companies.

“Very low emissions are not the end point. Shahe's glass industry is concentrated. Although each company has passed all standards. The environmental pressure in this region is still very high,” said Li Pengtao, deputy director of the Shahe Department of Environmental Protection. Shahe suggested that enterprises use “double emission intensity and total emissions”, “control” targets and measures. Corrective orders are created for companies that exceed monthly aggregate control targets.

Shahe City also plans to use resource elements intensively. Accelerate the construction of environmentally friendly, low-carbon, efficient, clean, centrally managed pollution and waste production systems.

After the Lunar New Year holiday, Shi Donghui, who is in charge of environmental protection work for the Hebei Xiahe Economic Development Zone Executive Committee, is busy completing a clean gas project. When completed, the project will create clean gas production capacity of 4.5 million cubic meters per day. Shahe will fundamentally change the energy structure of the glass industry.

Shi Donghui said, "This project can completely replace the gasifier in the existing coal-fired glass production line and has great environmental benefits." It is estimated that after the project starts, annual coal consumption will be reduced by 900,000 tonnes, and emissions will be reduced due to significant reductions in particulates, sulfur dioxide and nitrogen oxides.

Reporters walking the streets of Shahe could see trucks carrying glass at any time. Some business executives told reporters that the stock balance at the end of last year is slowly declining, and everyone is making every effort to welcome the new year. "A good start"

[bozoid 2023] Technology to help protect and manage the black land

Tue, 31 Jan 2023 17:43:12 +0800

Black soil is a rare treasure of the earth. In recent years, Huachuan County, Jiamusi City, Heilongjiang Province has seriously promoted the land cultivation model, used soil testing and milk powder fertilizer technology, built an integrated water and fertilizer pipeline system, and built standard farmland. Soil protection so that black soil is fertilized and green.

It is covered in silver along the Songhua River. Many farmers are already busy in the black soil of the Sanjiang Plain. It is the first entry point of Huachen County along the "Three Rivers 100km Green Rice Corridor" starting from the downtown area of Jiamutsi City in Heilongjiang Province and heading east. In the village of Shuanxin, Huachuan Province, several spray trucks were roaring and "smoke" was billowing from behind them.

“Organic fertilizers can increase soil temperature, activate nutrients, thicken black soil and improve soil fertility.” Zhao Deshan, general manager of Yucheng Modern Agricultural Cooperatives in Huachuan Province, introduced that 12,000 acres of cooperative land are used and organic fertilizers are available. He has completed Green Organic certification.

Huachuan County borders the Songhua River to the north and Wanda Mountain to the south. In recent years, complex local agrotechnical and biological measures have undertaken reconstruction and restoration projects, built various long-term mechanisms, and taken numerous measures for black soil protection and conservation. Chen Guoyui, Director of Huachuan County Agricultural Development Center, said, "Last year, the total arable land area in the region was 2.1 million mu, with 1.1 million mu of green space and more than 800,000 mu of standard arable land."

Upgrade technology, save fertilizer and medicine

"This field can "grow" your table of meats and vegetables!" Zhao Deshan introduced the cooperative as a mix of duck rice, crab rice, shrimp rice and fish rice. This year the area will reach 4000 cubic meters. Cheerleaders eat insects.

A pile of official soil test fertilizer proposals and a pile of farming guidelines record the changes in the land before my eyes. The total amount of mineral fertilizers recommended for cards is decreasing year by year, but productivity is increasing year by year. Zhao Deshan said, “The average amount of mineral fertilizer per month has decreased in the past five years. More than 20 cats. Black soil has increased the fertility of our area.

At present, soil testing and fertilizer processing technology for key crops in Heilongjiang Province have basically achieved full coverage, and the total rice farming area has stabilized at more than 1 million. "About 150 acres of land are sampled. We sample farmland across the county to test soil formulas and then provide fertilizer recommendation cards." Introduced by Yan Zhongsheng, Director of Huachuan Provincial Agricultural Technology Development Center. , through the analysis of nitrogen, phosphorus, potassium, etc. in each area, the content of elements allows farmers to make up for existing deficiencies and adjust "nutritional food" fertilizers.

After the "fertilization" of black soil, preventive treatment is promoted. Powerful horse-drawn harvester, straw crusher, idle seeder... Zhao Deshan entered the agricultural machinery warehouse and introduced the newly purchased large agricultural machinery to reporters. With support from the 2015 pilot project, the Agricultural Technology Extension Center, all fields will adopt conservation farming techniques such as mulching and straw treatment.”

[bozoid 2023] Green technology helps Iceland quickly move towards carbon neutrality

Tue, 31 Jan 2023 17:31:49 +0800

Inside a small spherical dome near Iceland's Heilig geothermal power plant, carbon dioxide-rich water is pumped hundreds of meters into porous basalt rock, where the carbon dioxide reacts with metals in the rock to form carbonates. It is kept safe for thousands of years.

This project is one way to make Iceland carbon neutral. The website of the British magazine 'New Scientist' highlighted in a recent report that Iceland is developing a set of technologies aimed at achieving carbon neutrality by 2040, which could be 'green' for other countries as well.

Almost all electricity comes from renewable sources.

Iceland is ahead of other countries in renewable energy. In the 1930s, Iceland began to develop geothermal energy, and the first project was to provide hot water for swimming pools, schools and hospitals in the capital, Reykjavík.

In the 1970s, the Icelandic government pushed ahead with geothermal and hydroelectric power. Today Iceland's electricity comes almost entirely from renewable sources. About 70% is hydroelectric and 30% is geothermal.

Also, around 90% of Iceland's heat comes from hot water from geothermal power plants, and still only a handful of independent buildings use oil boilers. This puts Iceland far ahead of other EU countries, where on average only 23% of its heating and cooling energy comes from renewable sources.

In the current energy crisis due to geopolitical conflict, the merits of new and renewable energy are being emphasized. Rising electricity prices have taken a toll on residents and businesses in many places, but electricity costs remain low in Iceland. Iceland's cheap green energy has attracted a steady stream of companies such as data centers.

Iceland, which uses renewable electricity to power data centers or manufacture products sold abroad, is effectively exporting green energy around the world.

However, Iceland is still debating how much to expand renewable energy production to support the industry. Iceland still has plenty of electricity, but some of the best geothermal attractions are in scenic locations.
