The US President recently said the conflict between Russia and Ukraine had driven up the prices of all the world's major food staples, including wheat, corn, barley, oilseeds and edible oils, and that Russia and Ukraine together supplied more than 25% of the world's wheat exports and about 20% of its barley exports. 

To address the food shortage, the Biden administration says it plans to increase the number of counties eligible for insurance for double cropping. Double cropping is when farmers grow two different crops a year on the same field. 

Under Biden's plan, the number of counties eligible for two-season crop insurance would increase by 681, for a total of 1,935. 

The UN has warned that up to 1.7bn people are "highly exposed" to the domino effect of the conflict between Russia and Ukraine on the global food, energy, and financial systems.  The agency says conflict could increase hunger in countries where people are already suffering from malnutrition.

Even countries where food is less scarce are being hit by rising prices. U.S. grocery prices rose 1% in April, compared with a 10.8% increase over the past 12 months, the Labor Department said recently.

According to the White House, global food prices have risen nearly 13 percent since the outbreak of the Russia-Ukraine conflict. 

Besides, affected by the ever-changing international situation, the supply and prices of international bulk crystal vein graphite are still very uncertain.

Crystal vein graphite is also known as crystal vein, Sri Lankan graphite, Ceylon graphite and graphite. The names Sri Lanka and Ceylon are derived from the areas where this graphite is mined. It is only sourced and processed in Sri Lanka (formerly Ceylon), although this form of natural graphite is also found in the UK and USA.

The exact formation of crystalline vein graphite is uncertain, but it is suspected that the graphite is naturally occurring pyrolytic graphite. If it was deposited directly from the fluid phase, as this theory suggests, that would explain the graphite veins found in the ore rocks.

In layman's terms, a high temperature fluid may deposit solid graphitic carbon as it flows. Once the fluid cooled, this graphitic carbon formed graphite flows or veins in the surrounding rock. Carbon rich gases may react with the high temperature fluid to form deposited graphitic solids, or they may be absorbed as the fluid flows.

This formation helps to create a macroscopic form, like a small needle perpendicular to the wall of a vein. Such veins of natural graphite can be from a few centimetres thick to 2 metres thick. When sourced, the graphite ranges in size from powders as fine as 5 microns to lumps as large as 8 cm in diameter.

How does vein graphite compare to other natural graphites?

In many ways, vein graphite is the best quality natural graphite. Its graphite content can range from 94% to 99%, with the purest samples coming from the middle of the vein. It also has a higher thermal and electrical conductivity and a higher cohesive integrity than other types of natural graphite. These properties may be attributed to its needle-like structure.

What are the good uses of crystalline vein graphite?

Veined graphite can potentially be used in any situation where natural flake graphite would be suitable, but the properties of veined graphite would be slightly better. It is commonly used in automotive applications such as high performance clutches and brakes.

Vein graphite is unique in that it is considered to be a naturally occurring pyrolytic (deposited from a fluid phase) graphite. Vein graphite gets its name from the fact that it is found in veins and fractures in closed 'ore' rocks. This graphite is formed by the direct deposition of solid graphitic carbon by high temperature subsurface fluids called pegmatite fluids. Pegmatites form regionally or locally when large amounts of magma cool, or when some other source of 'geological energy' causes the surrounding rock to melt. Fluids from these sources are hot and aggressive at high pressures and may actually be in a state known as 'supercritical', a sub-stable fluid state that is neither liquid nor gaseous. Pegmatites represent substances distilled from heated rock because of their low solubility in the local system. If this fluid intrudes into pre-existing flake graphite deposits or other carbon-bearing rocks, the solid carbon present may be bound to the fluid as carbon dioxide, methane, carbon monoxide or other carbon-bearing fluid phases. Carbonaceous gases may also be formed by the reaction of carbonate mineral species with magma or other energy sources. If limestone, marble or other carbonate-rich mineral species are involved, significant amounts of carbonaceous gas may be formed as a result of the release of 'crystalline carbon dioxide.

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.

It is used in various high-tech fields, so the market demand for crystal vein graphite will continue to rise. We are a quality supplier of crystal vein graphite, please feel free to contact us.
