Big Data Superconductivity Nanotechnology And Quantum Computing

Graphene is renowned for its excellent electrical conductivity, which stems from its two-dimensional, one-atom-thick structure. Graphene is famously strong for its very thin structure, making it one of the strongest materials known. Graphene is made entirely of carbon, arranged in a hexagonal lattice. While it does have high optical transparency, its composition is carbon, not silicon. Its electrical conductivity, along with its optical transparency, makes graphene an excellent candidate for use in conducting electrodes for various display technologies. So, statements 1, 2 and 4 are correct.

**Statement 1 is correct:** Targeted drug delivery is a promising application of nanotechnology in medicine. Nanoparticles can be designed to carry drugs specifically to diseased cells, reducing side effects and improving treatment efficacy. **Statement 2 is correct:** Nanotechnology is being explored for gene therapy by creating nanocarriers that can deliver genetic material (e.g., DNA or RNA) into specific cells. This holds the potential for treating various genetic disorders. Therefore, both statements are correct.

**Pair 1 is incorrect:** The Belle II experiment is a particle physics experiment designed to study the properties of B mesons. It is not related to artificial intelligence. **Pair 2 s correct:** Blockchain technology is the underlying technology behind cryptocurrencies like Bitcoin. It is a distributed ledger technology that ensures secure and transparent transactions.  **Pair 3 is incorrect:** CRISPR-Cas9 is a gene-editing technology used in the field of molecular biology to edit genes. It is not related to particle physics.  Therefore, only pair 2 is correctly matched.

**Statement 1 is correct.** Carbon nanotubes are being explored for their potential use as drug and antigen carriers in the human body. Their unique properties allow them to attach drugs or antigens and deliver them to specific target cells. **Statement 2 is incorrect.** While research is ongoing, using carbon nanotubes for artificial blood capillaries in the human body is still in the theoretical or experimental stages. **Statement 3 is correct.** Carbon nanotubes show promise in developing biosensors due to their high electrical conductivity and sensitivity to changes in their environment. This makes them suitable for detecting biomolecules like enzymes, DNA, or toxins. **Statement 4 is partially true.** Some studies have found that carbon nanotubes are non-degradable, also some studies have shown them to be degradable. The official answer key of the UPSC has given 'C' as the correct answer.

**Statement 1 is incorrect:** Nanoparticles can exist in nature (natural nanoparticles). Volcanic eruptions, forest fires, and natural weathering processes can all create nanoparticles. **Statement 2 is correct:** Some cosmetics incorporate nanoparticles of ingredients like zinc oxide or titanium dioxide for sun protection or other purposes. **Statement 3 is also correct:** The safety of nanoparticles in consumer products is a complex issue and a growing area of research. Some nanoparticles might pose potential health or environmental risks depending on their specific properties and how they interact with the body or the environment.

* Carbon fibres are highly valued for their unique properties like strength, lightness, and stiffness. They are widely used in the manufacturing of various components in automobiles and aircraft to reduce weight and improve performance. * Carbon Fiber Recycling: While traditional carbon fibre recycling methods were limited, advancements are being made in this field. Here are some possibilities 1. **Mechanical recycling** - This process breaks down carbon fibres into smaller pieces for use in applications where their original form is not necessary. 2. **Chemical recycling** -This method dissolves the resin holding the fibres together, potentially allowing the extraction of reusable carbon fibres. 3. **Thermal recycling** - High temperatures are used to convert the resin into usable materials while recovering the carbon fibres. * These recycling technologies are still evolving, but they offer a more sustainable approach to using carbon fibres. **Hence, statement 2 is incorrect.**

**Statement 1 is correct:** Hydrogels are widely used in biomedical applications, especially in controlled drug delivery systems. Their high water content, biocompatibility, and ability to swell and release drugs in a controlled manner make them ideal for: - Transdermal drug delivery - Oral and ocular delivery - Injectable drug systems **Statement 2 is incorrect:** Hydrogels are not commonly used in mobile air-conditioning systems. These systems typically use refrigerants and mechanical components (like compressors, condensers, and evaporators) to provide cooling. While hydrogels can absorb and release moisture, they are not suitable for the cooling and dehumidification processes involved in air conditioning. **Statement 3 is incorrect:** Hydrogels are not used in the formulation of industrial lubricants. Lubricants generally consist of base oils (mineral, synthetic, or vegetable) and additives for enhancing properties like viscosity, anti-wear, and corrosion resistance. Hydrogels do not possess the required lubricating properties, especially under high pressure and temperature conditions.
