With reference to the hematene, consider the following statements: It ...
Statement 1: It is extracted from naturally occurring hematite.
Hematene is a recently discovered material that is derived from hematite, which is a naturally occurring mineral. Hematite is an iron oxide mineral that is commonly found in rocks and soils. Hematene is formed by extracting the layers of hematite using a process called liquid exfoliation. This process involves immersing hematite in a liquid solvent and applying ultrasonic waves to separate the layers of the mineral. The resulting material, hematene, retains the properties of hematite but in a much thinner and more flexible form. Therefore, statement 1 is correct.
Statement 2: It is not capable of withstanding high laser intensities.
Hematene, being derived from hematite, possesses unique properties that make it suitable for various applications. One of its notable properties is its ability to withstand high laser intensities. Hematene has been found to exhibit excellent optical properties, including high absorption and low reflectivity, which make it suitable for use in optoelectronic devices such as photodetectors, solar cells, and optical switches. These properties indicate that hematene can indeed withstand high laser intensities. Therefore, statement 2 is incorrect.
In conclusion, statement 1 is correct as hematene is indeed extracted from naturally occurring hematite. However, statement 2 is incorrect as hematene is capable of withstanding high laser intensities. Therefore, the correct answer is option A, both statements are not correct.

With reference to the hematene, consider the following statements: It ...
Researchers have come up with a new and highly efficient optical limiter using a novel 2D material, ‘hematene’.
- Nanoflakes of a material called hematene extracted from iron ore have been found capable of withstanding and acting as shield from high laser intensities.
- Hence it could be used to make devices called optical limiters that can protect sensitive optical equipment from light-induced damage.
- Radiation from laser sources is highly concentrated and powerful and can be detrimental to sensitive equipment such as sensors, detectors, and other optical devices.
- When the input intensity increases optical limiters control the amount of light that passes through, thereby preventing damage to the optical component.
- These devices are often useful in laser technologies, military, telecommunications, aircrafts, and scientific research in several ways.
- They found that 2D nanoflakes of hematene is capable of withstanding very high laser intensities, and they exhibited excellent optical limiting of green laser light (532 nm) while maintaining a high linear transmission (about 87%) for low-intensity light.
Key facts about Hematene:
- It is extracted from naturally occurring hematite, the mineral form of iron(III) oxide, using a combination of sonication, centrifugation and vacuum-assisted filtration.
- It measures 3 atoms thick and has a more efficient photocatalysis.
- It is ferromagnetic (the mechanism by which certain materials like iron form permanent magnets, or are attracted to magnets) like a common magnet.
- It is capable of withstanding and acting as shield from high laser intensities.
Hence only statement 1 is correct.
