Much of the modern information era would not be possible without silicon and Moore’s Law, and electric cars would be much less viable without recent advances in the material science behind lithium-ion batteries. That’s why graphene, a two-dimensional supermaterial made from carbon, is so exciting. It’s harder than diamonds, 300x stronger than steel, flexible, transparent, and a better conductor than copper (by about 1,000x). If it lives up to its potential, graphene could revolutionize everything from computers to energy storage.
Graphene: Is It the Next Wonder Material?
The following infographic comes to us from 911Metallurgist, and it breaks down the incredible properties and potential applications of graphene.
While the properties and applications of graphene are extremely enticing, there has one big traditional challenge with graphene: the cost of getting it.
The Ever-Changing Graphene Price
As you can imagine, synthesizing a material that is one atom thick is a process that has some major limitations. Since a sheet of graphene 1 mm thick (1/32 of an inch) requires three million layers of atoms, graphene has been quite cost-prohibitive to produce in large amounts. Back in 2013, Nature reported that one micrometer-sized flake of graphene costed more than $1,000, which made graphene one of the most expensive materials on Earth. However, there has been quite some progress in this field since then, as scientists search for the “Holy Grail” in scaling graphene production processes. By the end of 2015, Deloitte estimated that the market price per gram was close to $100. And today, graphene can now be ordered straight from a supplier like Graphenea, where multiple products are offered online ranging from graphene oxide (water dispersion) to monolayer graphene on silicon wafers. One producer, NanoXplore, even estimates that graphene is now down to a cost of $0.10 per gram for good quality graphene, though this excludes graphene created through a CVD process (recognized as the highest level of quality available for bulk graphene). The following graphic from Nature (2014) shows some methods for graphene production – though it should be noted that this is a quickly-changing discipline.
As the price of graphene trends down at an impressive rate, its applications will continue to grow. However, for graphene to be a true game-changer, it will have to be integrated into the supply chains of manufacturers, which will still take multiple years to accomplish. Once graphene has “real world” applications, we’ll be able to see what can be made possible on a grander scale. on Did you know that nearly one-fifth of all the gold ever mined is held by central banks? Besides investors and jewelry consumers, central banks are a major source of gold demand. In fact, in 2022, central banks snapped up gold at the fastest pace since 1967. However, the record gold purchases of 2022 are in stark contrast to the 1990s and early 2000s, when central banks were net sellers of gold. The above infographic uses data from the World Gold Council to show 30 years of central bank gold demand, highlighting how official attitudes toward gold have changed in the last 30 years.
Why Do Central Banks Buy Gold?
Gold plays an important role in the financial reserves of numerous nations. Here are three of the reasons why central banks hold gold:
Balancing foreign exchange reserves Central banks have long held gold as part of their reserves to manage risk from currency holdings and to promote stability during economic turmoil. Hedging against fiat currencies Gold offers a hedge against the eroding purchasing power of currencies (mainly the U.S. dollar) due to inflation. Diversifying portfolios Gold has an inverse correlation with the U.S. dollar. When the dollar falls in value, gold prices tend to rise, protecting central banks from volatility. The Switch from Selling to Buying In the 1990s and early 2000s, central banks were net sellers of gold. There were several reasons behind the selling, including good macroeconomic conditions and a downward trend in gold prices. Due to strong economic growth, gold’s safe-haven properties were less valuable, and low returns made it unattractive as an investment. Central bank attitudes toward gold started changing following the 1997 Asian financial crisis and then later, the 2007–08 financial crisis. Since 2010, central banks have been net buyers of gold on an annual basis. Here’s a look at the 10 largest official buyers of gold from the end of 1999 to end of 2021: Rank CountryAmount of Gold Bought (tonnes)% of All Buying #1🇷🇺 Russia 1,88828% #2🇨🇳 China 1,55223% #3🇹🇷 Türkiye 5418% #4🇮🇳 India 3956% #5🇰🇿 Kazakhstan 3455% #6🇺🇿 Uzbekistan 3115% #7🇸🇦 Saudi Arabia 1803% #8🇹🇭 Thailand 1682% #9🇵🇱 Poland1282% #10🇲🇽 Mexico 1152% Total5,62384% Source: IMF The top 10 official buyers of gold between end-1999 and end-2021 represent 84% of all the gold bought by central banks during this period. Russia and China—arguably the United States’ top geopolitical rivals—have been the largest gold buyers over the last two decades. Russia, in particular, accelerated its gold purchases after being hit by Western sanctions following its annexation of Crimea in 2014. Interestingly, the majority of nations on the above list are emerging economies. These countries have likely been stockpiling gold to hedge against financial and geopolitical risks affecting currencies, primarily the U.S. dollar. Meanwhile, European nations including Switzerland, France, Netherlands, and the UK were the largest sellers of gold between 1999 and 2021, under the Central Bank Gold Agreement (CBGA) framework. Which Central Banks Bought Gold in 2022? In 2022, central banks bought a record 1,136 tonnes of gold, worth around $70 billion.

China continued its gold-buying spree with 62 tonnes added in the months of November and December, amid rising geopolitical tensions with the United States. Overall, emerging markets continued the trend that started in the 2000s, accounting for the bulk of gold purchases. Meanwhile, a significant two-thirds, or 741 tonnes of official gold purchases were unreported in 2022. According to analysts, unreported gold purchases are likely to have come from countries like China and Russia, who are looking to de-dollarize global trade to circumvent Western sanctions.
