In the future, the courier will have to go to the collection point to pick it up? It is against the rules to refuse door-to-door delivery.

  Beijing, April 11 (Reporter Qiu Yu) How do you usually receive express delivery? In recent years, there are more and more express collection points and intelligent express cabinets, which makes people not worry about no one receiving goods at home, but it has caused new problems — — There is someone at home, but the courier is unwilling to deliver it to your door.

  Mr. Tang, who lives in Chaoyang District, Beijing, told reporters that on the 9 th, Yuantong courier sent his courier to the post office (a supermarket in the community) and only sent a short message to let him pick it up. Mr. Tang had someone at home at that time. When he asked the courier about the situation, he was told that "it would not be delivered to the door".

  "I called customer service twice and conducted an online manual service. Three customer services said.Now they all pick themselves up at the post office. They say this is a policy of express delivery now.Yuantong is only the first to implement it.All couriers will do this in the future.. "Mr. Tang said.

  Recently, Ms. Zhang from Daxing District, Beijing has also encountered the same trouble. The community where she lives is relatively large, and there are three or four yuantong post stations. The courier didn’t even tell exactly which post station to pick up, which led her to run several places to find the parcel.

  The reporter learned that not only Yuantong, but also other express delivery companies such as Yunda and Zhongtong in Beijing also have the above situation.

  "If the smart courier cabinet at the entrance of the community still has an empty position, it is usually placed in the cabinet. If you want to deliver it to your door, you need the sender to make a note." A Yunda courier in Fengtai District, Beijing said.

  Does the express delivery have to be delivered to your door? Is it in line with the regulations to put the courier at the collection point or courier cabinet without consulting the recipient, and then notify it by text message or telephone?

  Zhao Xiaomin, CEO of Guanshuo Enterprise and an expert in express delivery, pointed out in an interview with Zhongxin.com that according to the regulations, if a courier wants to put it in a collection point or an express cabinet, he must first obtain the consent of the recipient, and if the recipient does not agree, he must deliver it to the door.

  "Put the courier at the collection point first, and then send a text message to inform, which is wrong from the procedural point of view. It should be ‘ Send first and then release ’ 。” Zhao Xiaomin said.

  The reporter noted that China’s first administrative regulation specifically for the express delivery industry — — The "Provisional Regulations on Express Delivery" also has clear provisions on express delivery, which will come into force on May 1, 2018.

  The "Regulations" stipulate that an enterprise engaged in express delivery business shall deliver the express mail to the agreed receiving address, the recipient or the agent designated by the recipient, and inform the recipient or the agent to face-to-face acceptance. The consignee or agent has the right to face-to-face acceptance.

  In life, some smart express cabinets have been marked with relevant reminders to get the consent of the recipient first.

  A reminder posted on the HIVE BOX Express Cabinet outside a residential area in Fengtai District said, "Please ask the customer’s permission before putting the express into the container".

  However, in terms of home delivery, couriers also have their own difficulties.

  For example, some communities prohibit express vehicles from entering; The house number on some express orders is inaccurate; Often encounter the situation that the recipient is not at home, resulting in reduced delivery efficiency and backlog of express mail; Worried that the express car or the express mail in the car will be stolen.

  In this regard, Shao Zhonglin, former deputy secretary-general of China Express Association, pointed out in an interview that it is precisely because couriers have these difficulties that the state also encourages the "last mile" distribution to be diversified.

  The "Provisional Regulations on Express Delivery" clearly stipulates that multiple enterprises engaged in express delivery business are encouraged to share terminal service facilities to provide users with convenient express terminal services.

  Shao Zhonglin said,In the future, the proportion of express smart cabinets and collection points will increase. But he also stressed that door-to-door delivery is a basic requirement..

  "The industry encourages the diversification of express terminal services, but the premise of this diversification is that no matter which delivery method is chosen, the opinions of the recipients should be sought." Shao Zhonglin said. (End)

Ideal 4S Salesman: Ask the ugly M7! Second-hand prototype, it costs 30 thousand yuan.

Zhidian Travel obtained a screenshot of a WeChat circle of friends who was suspected to be a car salesman. When he introduced it, he said: Yu Dazui (Yu Chengdong) said that Huawei does not build cars, but only provides cars and assisted driving, and you (the car manufacturer) provide the original models. Therefore, there is a fundamental reason why M7 is ugly. Well-off designers design well-off businesses, but the design is almost meaningless!

He also said that the original model of M7 (which is no longer out of print) wanted to buy a second-hand five sets of the whole network. If you want to bargain with the boss, it is estimated that you can sell it at 30,000 yuan, because the risk factor of car collection is not inferior to Weimar.

From dangerous goods to safe endurance, they have created a rechargeable world.

  When going out, only one thing is allowed, and many people will choose mobile phones; To buy your first car, you may want to try a new energy electric car & HELIP; …

  These common choices in our daily life all exist because of the same thing — — Lithium battery.

  At 17: 45 Beijing time yesterday, the Royal Swedish Academy of Sciences announced that the 2019 Nobel Prize in Chemistry was awarded to Professor John B Goodenough, Professor Stanley Whittingham and Professor Yoshino in recognition of their contributions to the development of lithium batteries.

  The Nobel Prize in Chemistry once again makes people feel that they have flown from the top of the academic pyramid to ordinary people. The distance is so close, even within reach.

  With the lightest metal in the world

  Win the heaviest prize in the world

  When the power of your mobile phone is only 10%, I believe that many people’s anxiety and tension have reached the peak. At this time, if you suddenly find a charging treasure, it seems that life has been saved at that moment.

  Modern people can’t imagine life without the assistance of lithium batteries.

  Therefore, when the Royal Swedish Academy of Sciences awarded the 2019 Nobel Prize in Chemistry to three scientists from the United States, Britain and Japan who made outstanding contributions to the development of lithium batteries, people at the scene were extremely interested in it.

  Lithium, the least dense and lightest metal in the world.

  Although it is light and small, it has a big temper — — It is the most active metal among known elements (including radioactive elements).

  Therefore, it has become a very good material for developing batteries, but it has both advantages and disadvantages. When lithium metal is used as the electrode, there are huge hidden dangers — — This kind of battery is easy to catch fire or even explode.

  Therefore, if you want to use lithium in the battery, you must control it, and this year’s Nobel Prize winner in chemistry’s achievement actually lies in this.

  In other words, if these three scientists didn’t make Li obedient, we would be carrying an explosive bag every day and risking being ignited at any time by calling the Internet.

  So, how did they tame lithium?

  Originally, Goodenough and others found that manganese spinel is an excellent cathode material with low price, stability and excellent electrical and lithium conductivity. Its decomposition temperature is high, and its oxidation is much lower than that of lithium metal. Even if there is short circuit and overcharge, the danger of combustion and explosion can be avoided.

  Now, let’s imagine lithium cobaltate, and imagine it as a sandwich made of cobalt and oxygen. The lithium atom is the ham slice in the middle, which can be easily pulled out, so that the lithium atom can move quickly in the lithium cobaltate crystal — — Therefore, lithium cobaltate can replace metallic lithium as a lithium ion provider in the battery.

  At the same time, this oxide can also increase the voltage of the battery and the amount of electricity stored in the battery. More importantly, it is like putting a spell on lithium, making it docile and controllable.

  Liberal arts cross science and physics cross chemistry.

  Hard core life of 97-year-old father

  After briefly talking about the principle of lithium batteries, let’s talk about these three award-winning legends.

  At the age of 97, Goodenough is the oldest Nobel Prize winner so far.

  The old man’s life is quite hard — — After Goodenough was admitted to Yale University, he actually chose classical literature and philosophy as his first major. In order to get credit, he took two chemistry courses. When he graduated, his degree turned out to be a bachelor of mathematics. Because a math professor saw his talent, he was persuaded from a liberal arts student to a science student studying mathematics.

  Then, World War II broke out, and Goodenough joined the US Air Force. After retiring, at the age of 30, he went to the University of Chicago to study physics, and studied solid-state physics. After graduation, he went to Lincoln Laboratory of MIT and made contributions to the development of random access memory. This technology is the later computer memory.

  This wave of cross-border is not over yet — — In Lincoln Lab, Goodenough studied sodium-sulfur batteries. But it was not until 1976, at the age of 54, that he entered the Department of Chemistry of Oxford University in England, and his research field shifted to batteries, and he studied lithium cobaltate.

  That is, when Goodenough went to Oxford University, England, Whitingham, the founder of rechargeable lithium-ion battery, and his team had made the world’s first rechargeable lithium-ion battery — — They creatively used titanium sulfide as the cathode material and lithium metal as the cathode material. When charging, lithium ions move from the positive electrode to the negative electrode, and the discharge returns to the positive electrode, and so on.

  In 1977, the two high-energy scientists also co-published a book in the field of solid-state energy chemistry.

  On the other side of the globe, some Japanese companies, especially Sony, had made great progress in the commercialization of lithium rechargeable batteries and held a large number of patents.

  Akira Yoshino, after graduating from the Petrochemical Department of the Faculty of Engineering of Kyoto University with a master’s degree in engineering, directly entered Asahi Kasei Industrial Co., Ltd. In 1981, the research and development of lithium batteries began.

  He plays the role of matchmaker — — After establishing the basic framework of lithium-ion batteries, Yoshino made use of graphite, which has been invented by Sony Corporation of Japan and is used as the negative electrode of lithium batteries, with stable structure and low price, to draw a red line for lithium cobaltate as the positive electrode.

  In 1983, Yoshino made the world’s first rechargeable lithium-ion battery prototype by using lithium cobaltate cathode and polyacetylene anode. In 1985, many technical problems were overcome, metal lithium was completely eliminated, and the basic concept of rechargeable lithium-containing alkaline lithium-ion battery was established, and modern lithium-ion battery was born. In 1991, Sony released the first commercial lithium-ion battery in human history.

  "I’m only in my 90 s and I still have time."

  Three scientists are still working at an advanced age.

  Although the principle of the battery looks simple, the design and manufacturing process of the battery is very complicated. Until now, some alkaline batteries invented in the 19th century are still in use. It can be seen how difficult it is to invent and improve a new battery.

  This award is well deserved.

  In the "Nobel Prize" field, Goodenough is somewhat known as "Haruki Murakami" in the chemical field — — The voice is very high, "running with you" for many years.

  It is understood that 97-year-old Goodenough is still engaged in energy research.

  "I want to solve this problem before I die. I am only in my 90 s and I still have time." Goodenough hopes to develop solid-state batteries with high energy density and high safety, so that electric vehicles can replace high-capacity batteries of gasoline vehicles. He likes his metaphor of "crawling tortoise". "This kind of crawling throughout your life may bring benefits, especially if you cross different fields and collect all kinds of clues all the way. You have to have a lot of experience to integrate different ideas. "

  Whitingham, 78, is still thinking and working. He has also co-written books to observe and analyze the history, evolution and future state of energy storage, which describes the future development of lithium batteries.

  Just after being told that he won the Nobel Prize in Chemistry, 71-year-old Akira Yoshino replied in an interview with the media: "Curiosity" is the biggest driving force. Prior to this, Akira Yoshino said that battery technology is a complex and difficult interdisciplinary field, and its development needs many experts. Lithium-ion batteries are the result of collective wisdom.

Italy: entertainment venues for young patients are closed for three weeks.

       Cctv newsAccording to the data released by the Italian civil protection department on the 16th, there were 479 new confirmed cases in Italy within 24 hours. According to the data of the German CDC on the same day, there were 625 new confirmed cases in Germany compared with the previous day, and the cumulative number of confirmed cases exceeded 220,000; Romania reported 1087 new confirmed cases in the country on the same day. The number of new cases is still high, and governments around the world have tightened prevention and control measures to prevent the epidemic from getting out of control.

       Due to the obvious increase in the number of new cases in a single day recently, and most of the patients are young people, the Italian government issued a decree on the 16 th, stipulating that discos, dance halls, nightclubs and similar entertainment venues across Italy will be suspended for three weeks from the 17 th; From 6 pm to 6 am every day, people must wear masks in all outdoor places where there is a risk of gathering and a safe distance cannot be guaranteed. Italy will resume classes in September, and experts are generally worried that the resumption of classes is likely to lead to a larger outbreak.

       The COVID-19 epidemic report released by robert koch Institute, a German disease control agency, on the 15th said that the epidemic situation in Germany has been rebounding continuously since the beginning of July, and the development situation is "worrying". At present, there is no available COVID-19 vaccine and effective therapeutic drugs. Generally speaking, the COVID-19 epidemic still poses a "high risk" to the health of the German population. At the same time, German federal states have entered the school season since the beginning of August, and the state governments have formulated different epidemic prevention measures in schools according to the actual situation of the epidemic. Some primary and secondary schools in several federal States began the new semester experience week, requiring students to strictly abide by the mandatory regulations on masks.

       According to the data of COVID-19 epidemic released by Romania on the 16th, the detection volume in the past 24 hours was only 11,846, but there were as many as 1,087 newly confirmed cases. The Romanian government announced that the alert state for epidemic prevention and control would be extended for another month from the 16th.

       With the gradual relaxation of epidemic prevention policy and the continuous promotion of resumption of work and production, the epidemic situation in France has rebounded. In the past week, the average number of new cases in a single day exceeded 2,000, a record high since April.
