Analysts at JPMorgan recommended selling or "underweight" emerging market local currency sovereign debt because of the global impact of the Ukraine-Russia crisis.

JPMorgan estimated that fixed-income assets in emerging markets have lost 6-9 percent of their value since Russia invaded Ukraine a month ago, with nervousness about the war and its impact on global energy and food prices adding to existing pressures.

Some leading emerging market central banks are signaling that interest rates now need to rise faster than previously expected, which fuels fears of "stagflation". Stagflation means when high inflation and higher interest rates undermine economic growth.  

With both the U.S. Federal Reserve and emerging market central banks raising interest rates, JPMorgan also said it made sense to "underweight" emerging market assets by taking advantage of the recent pullback in local currency bond yields relative to TREASURIES.  

JPMorgan said major metals exporters such as South Africa, Chile, and Peru could still do well, but warned that emerging market fixed income assets now faced a more "stagflationary" trajectory.

The markets and prices of many commodities, metals, chemicals like the Aluminum Nitride, Aluminum Nitride Overview, Aluminum Nitride Applications, Aluminum Nitride Suppliers, Aluminum Nitride Price still face uncertainty.

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.

Important discoveries have been made in the study of anticancer drugs inhibiting the growth of gastric cancer cells in my country. According to "Science and Technology Daily", a research report provided by Ai Jun and others from the Fourth Hospital of Hebei Medical University showed that seven anticancer drugs including cisplatin had obvious inhibitory effects on gastric cancer cells (BGC-823) in vitro. However, there are certain differences, and it is ideal to use a medium concentration for 48 hours.
