As the world becomes increasingly digital and interconnected, the importance of robust cybersecurity measures cannot be overstated. With the advent of powerful quantum computers on the horizon, traditional cryptographic systems are facing unprecedented challenges. This urgency gave rise to the Post-Quantum Cryptography (PQC) initiative, notably highlighted during the PQC 2020 conference, which focused on developing cryptographic systems secure against quantum attacks.

Calcium carbonate find applications across various sectors. In the automotive industry, it is used in interior and exterior parts to enhance strength and reduce weight. In the construction sector, it serves as a filler in PVC, improving the performance and reducing costs of window profiles and siding. Additionally, in consumer products, it is widely used in packaging materials, household items, and medical devices due to its safety and stability.


In addition to coagulants like alum, flocculants are also widely used in sewage treatment. Polyacrylamide is a common flocculant that enhances the agglomeration of particles, making them easier to remove during the clarification process. By promoting the formation of larger and denser flocs, polyacrylamide can significantly improve the efficiency of solid-liquid separation, reducing the overall volume of sludge generated.


In conclusion, QQ has journeyed through a dynamic landscape of digital communication, adapting and evolving to meet the changing needs of its users. As it faces new challenges and competitions, its foundational role in the development of social communication in China remains undeniable. The future of QQ will undoubtedly be shaped by ongoing advancements in technology and shifting cultural behaviors, but its legacy as a pioneer in instant messaging is firmly established. The story of QQ is one of resilience, adaptation, and an enduring commitment to connecting people in an increasingly digital world.
