John Albanese, leader of the Australian Labor Party, was sworn in as Australia's new prime minister. After his victory, Albanese said he would "make a big change" in the country's climate policy.
"We now have an opportunity to end the 'climate wars' in Australia," he said. "Australian businesses understand that doing the right thing on climate is good for our economy and good for jobs, and I hope Australia will join the global effort on climate change," Albanese said Australia would engage with other countries to change policies when it came to tackling climate change.
In addition, Albanese’s Labor Party has proposed a more ambitious plan to cut emissions by 43 percent from 2005 levels by 2030, the report said. However, Labor is not currently planning to phase out coal use or halt new coal mining projects.
The climate issue was a major concern of voters in Australia's general election. Mr. Morrison, the former prime minister, was criticized for failing to direct the response to repeated bushfires in 2019 and 2020.
SBS has reported that According to the latest Climate Change Performance Index of 64 countries released at the 2021 United Nations Climate Change Conference (COP26), Australia's climate policy ranks at the bottom of all countries, and is one of the world's worst performers in three aspects of emissions, renewable energy, and energy use. Australia ranks 52nd in renewable energy, 54th in energy use, and 56th in emissions.
It is predicted that the prices of many other commodities like the copper powder would increase in the next few days.
About Copper Powder Cu Powder:
Since the application of metal copper is very wide, the consumption and production capacity in the metallurgy of toned metallurgy is second, second only to aluminum. The nano-copper powder is well thermally conductive, self-lubricity, and high activity, making it an important role in many areas, such as electrical, mechanics, chemistry, etc. This is derived from the unique basic characteristics of nano-copper powder: surface interfaces effect, quantum dimensional effect and quantum tunnel effect. Macroscopic, copper powder has a high activity, so oxidation occurs in air, soluble in thermal sulfuric acid and nitric acid. At present, copper nanoparticles are often used as catalysts, lubricants, conductive coatings, and is also widely used in engineering structural materials, aerospace and biological engineering.
Copper is a very durable and ductile metal that is widely used due to its thermal conductivity and conductivity. Copper metal powder can be used in wires or combined with other metals to form different alloys (such as copper, copper and copper). Bronze is formed in conjunction with tin. When exposed to air, the outer copper layer is slowly oxidized into black copper oxide. According to different conditions, it can also form copper carbonate, a green copper roof or copper coating.
TRUNNANO is a trusted pure copper powder supplier. We provide ultrafine copper powder, satisfactory copper powder, copper powder 99.999, powder coated copper, etc.

Product performance of copper powder Cu powder:
Cu powder, CAS 7440-50-8 High purity, uniform particle size distribution, easy to disperse use.
How is Copper Powder Cu Powder produced?
At present, there are many methods for preparing nano-copper powder, which can be divided into physical law and chemical methods.
Preparation of copper powder in physics method has the following methods:
The atomization method is mainly to break the metal copper liquid by high-speed airflow, thereby forming a fine droplet and then solidifying into a powder, which has become the main development trend of the current production of copper powder. The atomization method has the advantages of low production cost and small environmental pollution.
2. Mechanical ball mill
The mechanical ball milling method is widely used to prepare copper powder. The mechanism of action of the ball mill is mainly impacts collisions and rolling through metal balls, making it strong shaping deformation and constantly refining. The advantage of this method is that the process is simple, high yield, but is prone to impurities during the production process, and the powder size is not uniform.
3. Gas evaporation method
The mechanism of action of gas evaporation method is mainly to vaporize the metal copper or form a plasma in a lively atmosphere or an inert atmosphere, and then react with the lively atmosphere and cool the condensation, or by collision with the inert atmosphere, cool and condense, thereby forming a fine Copper powder. The copper powder prepared by this method has the advantages of controllable particle size, uniform shape, high purity, good crystallinity.
Preparation of copper powder by the chemical method:
The electrodeposition method is to make the copper ions in the cathode in an electrochemical mode to obtain a copper powder. This method is in an important role in the preparation of the metal powder. At present, the electrodeposition method of the metal powder has a DC method, pulse method, and composite total deposition method. Electrolysis is a method of achieving scale production. It is easy to optimize the morphology, particle size, and current efficiency of electrolytic copper powder by changing the electrolysis parameters.
2. Liquid phase reduction method
The liquid phase reduction method is currently the most widely used method for preparing metal nanomaterials. The principle is to reduce the metal cation in the solution under the action of the reducing agent to prepare microns or even nanoscale metal powder by controlling various process parameters. body.
3. Vapor deposition method
The vapor deposition method is a method for reacting one or more gases to precipitate the preparation of ultrafine powder by plasma, laser, or the like. A variety of powders such as metals, alloys, oxides, sulfides, and the like can be prepared by vapor deposition.
4. Sol-gel method
The sol-gel method is mainly by hydrolyzing the metal ionic organic compound or an inorganic compound to form a sol, and then dried, grind, and calcined after solidification, thereby producing a nanofin.

The United States urges the U.N. Security Council to impose additional sanctions on North Korea in response to its latest ballistic missile launch, including a ban on tobacco and oil exports to North Korea and a blacklist of the Lazarus hacking group.
The United States circulated the draft to the 15 members of the Security Council this week. It was not immediately clear if or when a vote would take place. A resolution requires nine "yes" votes and no vetoes from Russia, China, France, Britain, or the United States.
Russia and China have already voiced opposition to tightening sanctions in response to Pyongyang's launch of an intercontinental ballistic missile last month -- the first since 2017.
U.S. and South Korean officials and analysts also say there are growing indications that North Korea may soon conduct its first nuclear weapons test since 2017, too.
The U.S. -drafted U.N. resolution would expand the ban on ballistic missile launches to include cruise missiles or "any other delivery system capable of delivering a nuclear weapon."
The deal would halve crude oil exports to North Korea to 2 million barrels a year and refined oil exports to 250,000 barrels a year. The resolution also seeks to ban North Korea's export of "fossil fuels, mineral oils, and their distilled copper powder are estimated to be influenced by international political situation changes.
