Global boron nitride market trend 2022-2026 Hexagonal Boron Nitride is 10 Times Stronger Than Graphene by Newsdesignerstudiostore

Since the beginning of this year, people around the world have felt the pressure of rising prices. Not only the rise in oil prices but also different industries have seen soaring prices. According to the latest data, from August 2021 to the present, the inflation rate in the United States has risen for 6 consecutive months, and this data has soared from the previous 5.3% to 7.9% today. Inflation in the United States, the global Many countries have been affected.
According to experts' forecasts, the inflation rate in the United States may exceed 10% this year, which will face the danger of collapse, which has a great impact on global inflation, including boron nitride.

Hexagonal boron nitride (H-BN) is a two-dimensional layered broadband-gap insulating material with good heat resistance, chemical stability, and dielectric properties. It is widely used in electronic devices.

Hexagonal boron nitride is structurally similar to graphene, consisting of a planar lattice of atoms arranged in interconnected hexagons. The only difference is that in graphene, all atoms are carbon, whereas, in H-BN, each hexagon contains three nitrogen atoms and three boron atoms.




Carbon-carbon bonds are among the strongest, so graphene is theoretically much stronger than H-BN. The strength and elastic modulus of the two materials are similar, and h-BN is slightly lower in comparison: graphene has a strength of about 130GPa and young's modulus of about 1.0TPa; The strength and modulus of H-BN are 100GPa and 0.8 TPA, respectively.
Despite its excellent mechanical properties, graphene has low crack resistance, which means graphene is brittle.
 
In 1921, British engineer Griffiths published a theoretical study of fracture mechanics, describing the failure of brittle materials and the relationship between the size of cracks in materials and the force required to make them grow. For hundreds of years, scientists and engineers have used this theory to predict and define the toughness of materials.
In 2014, a study by Professor Jun Lou and his team at Rice University showed that graphene's fracture toughness is consistent with Griffith's theory of fracture mechanics: when the stress applied to graphene is greater than the force holding it together, the cracks propagate, And the energy difference is released during crack propagation. 
H-bn is also thought to be vulnerable, given its structural similarity to graphene. However, this is not the case.
 
The scientists found that H-BN is 10 times more ductile than graphene. 
A team led by Prof. Jun Lou of Rice University and Prof. Hua Jian Gao of Nanyang Technological University in Singapore has found that the brittle H-BN is 10 times stronger than graphene in cracking resistance.  This finding runs counter to Griffith's fracture theory, and such anomalies have never been observed before in two-dimensional materials.  The related research results were published in Nature with the title "Intrinsic Toughening and stable crack propagation in Hexagonal Boron nitride". 
 
Mechanism Behind H-BN's Extraordinary Toughness 
To find out why, the team applied stress to the H-BN sample, using scanning electron microscopes and transmission electron microscopes to see as much as possible how the cracks occurred. After more than 1,000 hours of experiments and subsequent theoretical analysis, they discovered the mystery. 



Although graphene and H-Bn may be structurally similar, boron and nitrogen atoms are not the same, so there is an asymmetric arrangement of hexagonal lattice intrinsic in H-BN, unlike the carbon hexagon in graphene. That is, in graphene, the cracks tend to go straight through the symmetrical hexagonal structure from top to bottom, opening the bond like a zipper. The hexagonal structure of H-BN is slightly asymmetric due to the stress contrast between boron and nitrogen, and this inherent asymmetry of the lattice causes cracks to bifurcate, forming branches. 
And if the crack bifurcates, that means it's rotating. The existence of this steering crack requires additional energy to further promote the crack propagation, which makes the crack more difficult to propagate and effectively enhances the toughness of the material. That's why H-Bn shows more elasticity than graphene.
 
Due to its excellent heat resistance, chemical stability, and dielectric properties, H-BN has become an extremely important material for two-dimensional electronic and other 2-bit devices, not only as a support base but also as an insulating layer between electronic components. Today, h-BN's toughness makes it an ideal choice for flexible electronics and is important for the development of flexible 2D materials for applications such as two-dimensional electronics.
In the future, as well as being used in flexible electronic textiles, h-BN could also be used as flexible electronic skin and implantable electronics that can be connected directly to the brain.

The EU’s draft REPowerEU plan calls for an increase of 15TWh of rooftop PV capacity by 2022. The draft also calls for EU and national governments to take action this year to reduce the time required to obtain permits for rooftop PV installations to three months, and proposes that "all new buildings and existing buildings with an energy grade OF D or above should have rooftop PV installations by 2025".  

In addition, the European Commission is likely to set a target for installed PV capacity of 300GW by 2025 and 500GW by 2030. Some members are more aggressive, with Austria, Belgium, Lithuania, Luxembourg, and Spain demanding a 1TW target for 2030.  

The REPowerEU initiative, worth 195 billion euros, was proposed by the EU on March 8 to phase out member states' dependence on Russian fossil fuels by 2030. In a few days, the European Commission will present a package to implement the RePowerEU strategy.  

As an important application scenario of distributed PV, rooftop PV is not limited to land, and the development conditions are relatively convenient.  

Since the end of 2021, Spain, France, the Netherlands, and other countries have introduced policies and measures such as government subsidies, tax cuts, fee reductions, and accelerated grid-connection approval to encourage the development of distributed PV.  Europe's potential for rooftop PV is huge and will continue to be an important growth pole for the industry, according to Wood Mackenzie.
