Design a new emoji in the exact style and visual language of current iPhone emojis. The emoji should represent the collaboration between PJSC “Tatneft” and Kazan Federal University. Use the same clean gradients, bold outlines, and expressive simplicity typical of iOS emojis. Combine familiar emoji elements—such as 🤝 (handshake), 🏫 (university), 🛢️ (oil barrel), and 🧪 (science flask)—into a single, unified symbol that conveys a partnership between a major oil company and a scientific institution. It should look as if it belongs natively in the iOS emoji set.emoji
