The Biden administration plans to ease sanctions on Venezuelan oil to allow more of the country's crude to reach Europe.  

The U.S. will allow European companies still operating in Venezuela to immediately transfer more oil to the continent, while allowing Chevron to negotiate a resumption of operations in Venezuela, according to people familiar with the matter.  Venezuela's OPPOSITION, which is backed by the United States, is understood to favor the move.  Tight global oil supplies have sent crude and fuel costs soaring, threatening to add to already high inflation.  Increasing Venezuelan crude exports would help ease supply constraints while also helping to reduce Europe's dependence on Russian energy.

The US has sought to encourage talks between the Venezuelan government and the US-backed opposition to open the way to free and fair elections by extending a limited license held by Chevron to allow the oil company to maintain its operations in Venezuela and negotiate future operations.  

The United States reportedly did not extend a permit to Allow Chevron to drill and sell Venezuelan crude, as the company had hoped.  

The license extension will allow Chevron to negotiate with State-run Petroleos de Venezuela SA, with which it has a joint venture.  Previously, the company could not directly negotiate with any officials sanctioned by the United States.  Chevron has been lobbying the United States to allow it to drill for Venezuelan crude and sell it on world markets to help lower energy prices amid the Russia-Ukraine war.

Affected by the ever-changing international situation, the supply and prices of many commodities like the Aluminum Nitride, Aluminum Nitride Overview, Aluminum Nitride Applications, Aluminum Nitride Suppliers, Aluminum Nitride Price are still very uncertain.

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.

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 Aluminum Nitride, Aluminum Nitride Overview, Aluminum Nitride Applications, Aluminum Nitride Suppliers, Aluminum Nitride Price are estimated to be influenced by international political situation changes.
