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.

Aluminum Nitride Overview
Aluminum nitride is stable at high temperatures in an inert atmosphere, melting at temperatures around 2200°C. In a vacuum, AlN decomposes at about 1800°C. In air, surface oxidation occurs above 700°C. Surface oxide layers as thick as 5-10 nm can be detected even at room temperature. The oxide layer protects the material at temperatures up to 1370°C. Above this temperature, extensive oxidation will occur. Aluminum nitride is stable up to 980°C in hydrogen and carbon dioxide atmospheres.
AlN is stable up to 2200°C. The strength at room temperature is high, and the strength decreases slowly with the increase of temperature. Good thermal conductivity, small thermal expansion coefficient, is a good thermal shock material. It has strong corrosion resistance to molten metal, and is an ideal crucible material for casting pure iron, aluminum or aluminum alloy. Aluminum nitride is also an electrical insulator with good dielectric properties and is also promising as an electrical component. The aluminum nitride coating on the gallium arsenide surface protects it from ion implantation during annealing. Aluminum nitride is also a catalyst for the conversion of hexagonal boron nitride to cubic boron nitride. It reacts slowly with water at room temperature. It can be synthesized by aluminum powder in ammonia or nitrogen atmosphere at 800~1000℃, and the product is white to gray-blue powder. Or by the reaction of Al2O3-C-N2 system at 1600~1750℃, the product is off-white powder. Or prepared by the gas phase reaction of aluminum chloride and ammonia. The coating can be synthesized by the vapor deposition method of the AlCl3-NH3 system.
Application of Aluminum Nitride
Aluminum Nitride (AlN) is a diamond-like nitride inorganic non-metallic material with good thermal conductivity and low thermal expansion coefficient. It is a good thermal shock material. It has strong corrosion resistance to molten metal, and is an ideal crucible material for smelting and casting pure iron, aluminum or aluminum alloy. Aluminum nitride is also an electrical insulator, has good dielectric properties, and has good application prospects in the field of electronic component manufacturing.
1. Manufacture of integrated circuit substrates, electronic devices, optical devices, heat sinks, high-temperature crucibles, and preparation of metal-based and high-resolution composite materials
2. Thermally conductive silicon and thermally conductive epoxy resin.
3. Nano-lubricants and anti-wear agents.
4. High thermal conductivity plastic
Due to the piezoelectric properties of AlN, epitaxially grown thin-film crystalline aluminum nitride is used for surface acoustic wave sensors (SAW) deposited on silicon wafers. One application is RF filters, which are widely used in cell phones and are known as thin-film bulk acoustic resonators (FBARs). This is a MEMS device that uses aluminum nitride sandwiched between two metal layers.
Aluminum nitride is also used to construct piezoelectric micromachined ultrasonic transducers, which transmit and receive ultrasonic waves and can be used for aerial ranging up to one meter.

|Spherical Aluminum Nitride Health & Safety Information|
Cancer cells can "stretch out a big hand" and take away the mitochondria of immune cells. The Harvard Medical School research team cultured mouse and human breast cancer cells and immune cells, such as killer T cells, and used field emission scanning electron microscopy (FESEM) to observe the relationship between cancer cells and immune cells. interactive. Interestingly, they found that cancer cells stick out long nanotubes, typically within 100-1000 nanometers in diameter, each of which connects to multiple immune cells along the way. The researchers used the drug L-778123, which inhibits the formation of nanotubes, for treatment. The higher the concentration of L-778123, the better the treatment effect.
