mostly carbon, with hydrogen, oxygen, nitrogen, and sulfur also present) 15,000 to 18,000 BTUs: Excellent for most residential kitchens, handling heavy pans and boiling water efficiently. 20,000+ BTUs: Found in professional-style gas ranges and dedicated wok cooktops, providing restaurant-level heat and quick pan recovery when cold ingredients are added. Up to 200,000+ BTUs: Utilized in heavy-duty, high-pressure outdoor equipment like turkey fryers or crawfish boil setups Coal (approximate composition): C (mostly carbon, with hydrogen, oxygen, nitrogen, and sulfur also present) Coal tar: No single formula (mixture of hundreds of organic compounds) Anthracite coal: ~90–95% carbon (approximately C ) Bituminous coal: Mostly carbon, no fixed molecular formula Lignite: Mostly carbon, no fixed molecular formula --------------------------------------- NiMo/Al₂O₃ catalystNickel + molybdenumHydrotreating and coal liquefactionCoMo/Al₂O₃ catalystCobalt + molybdenumHydrodesulfur...

harvesting healthy stem cells (from the patient's own tissues or a donor) and injecting or transplanting them into a damaged area. 

Sensory cells (also called sensory receptor cells ) are specialized cells that detect changes in the body or environment and convert them into electrical signals for the nervous system. How they work Stimulus → Sensory receptor cell → Electrical signal → Sensory neuron → Brain & spinal cord → Perception or response Examples of sensory cells Photoreceptors (eyes) – detect light. Hair cells (inner ear) – detect sound and balance. Olfactory receptor cells (nose) – detect smells. Taste receptor cells (tongue) – detect sweet, sour, salty, bitter, and umami. Mechanoreceptors (skin) – detect touch, pressure, and vibration. Thermoreceptors (skin) – detect hot and cold. Nociceptors (skin and tissues) – detect pain. Chemicals inside sensory cells Water (H₂O) Cell membrane (phospholipids and cholesterol) Proteins (ion channels, receptors, enzymes) DNA RNA ATP (C₁₀H₁₆N₅O₁₃P₃) Ions: Na⁺, K⁺, Ca²⁺, Cl⁻ Neurotransmitters (depending on the sensory system), such as glutam...

Carbonmono Cracking (Thermal & Catalytic) 1. C₁₆H₃₄ → C₈H₁₈ + C₈H₁₆ (500°C, 20 atm) – Gas oil to gasoline + light olefins. 2. C₁₀H₂₂ → C₆H₁₄ + C₄H₈ (450°C, zeolite) – Diesel to gasoline + butene. 3. C₂₀H₄₂ → C₁₀H₂₂ + C₅H₁₀ + C₅H₁₀ (fluid catalytic cracking) – Heavy gas oil to light cycle oil + olefins. 4. C₇H₁₆ → C₃H₈ + C₄H₆ (550°C) – Heptane to propane + butadiene. 5. C₁₈H₃₈ → C₉H₂₀ + C₉H₁₈ (500°C) – Paraffin to gasoline + nonene. Hydrocracking 1. C₁₆H₃₄ + H₂ → 2 C₈H₁₈ (400°C, Ni-W catalyst) – Gas oil + hydrogen to isoparaffins (high octane). 2. Naphthalene + H₂ → Tetralin → Decalin (300°C, Pt) – Aromatic saturation to jet fuel. Catalytic Reforming 1. n-C₆H₁₄ → Cyclohexane → Benzene + 3H₂ (500°C, Pt-Re) – Paraffin to aromatics (RON boost). 2. Methylcyclopentane → Benzene + 2H₂ (480°C) – Naphthene to aromatic. 3. C₇H₁₆ → Toluene + 4H₂ (490°C) – Heptane to toluene. Isomerization 1. n-C₄H₁₀ → iso-C₄H₁₀ (150°C, AlCl₃) – Butane to isobutane (alkylation feed). 2. n-C₅H₁₂ → iso-C₅H₁₂ (12...
