Graphene is a two-dimensional crystal, which consists of carbon atoms with sp2 hybrid orbitals to form two-dimensional carbon nanomaterials with hexagonal honeycomb lattice.…
Although hydrogen fuel is a promising alternative to fossil fuels, the catalyst it relies on for power generation is mainly composed of rare and expensive metal platinum, which limits the wide commercialization of hydrogen fuel.…
Few layer graphene is a new two-dimensional carbon material with atomic thickness. It can be used as lithium battery anode material.…
Graphene oxide is an oxide formed by the oxidation of graphite by strong acid. It adopts the oxidation reaction of potassium permanganate in concentrated sulfuric acid and graphite powder to obtain a tan edge derivative carboxylic acid base and pheno…
The World Platinum Investment Association (WPIC) said recently that carmakers are accelerating reductions in palladium use and increased use of platinum due to concerns about Russian palladium supplies. However, it still expects a significant surplus…
Roche and its subsidiary TIB Molbiol have developed a series of tests for the detection of the monkeypox virus, the Switzerland-based pharmaceutical company announced. The monkeypox virus is a close relative of the smallpox virus, belonging to orthp…
Europe's largest economy, Germany, recently activated an emergency plan to manage gas supplies that the natural gas could be rationed if supplies are disrupted or disrupted by a stand-off over Russian demands to pay for fuel in rubles. German Vice-C…
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 all…
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…
Due to the properties of the chemical bonds between carbon atoms, graphene is very tough: it can be bent to large angles without breaking and withstand high pressures.…
Graphene — a two-dimensional carbon film just one atom thick — is an excellent material.…
A lead-acid battery (VRLA) is a battery whose electrodes are mainly made of lead and oxides, and the electrolyte is a sulfuric acid solution.…
