Soft Close Square Shape Toilet Seat
Square toilet seats are a common toilet accessory
Installation and use: when installing a square toilet seat, you need to follow the instructions in the product manual. Generally speaking, you need to fix the mounting feet first, and then place the toilet cover against the insert bar, and make sure that the front edge of the toilet is left with one to two centimetres of reserve. In the process of use, you need to pay attention to keep the toilet cover clean, avoid standing or placing heavy objects on the toilet cover to ensure its normal use and prolong its service life

A breakthrough in graphene production has been made by researchers at Northwestern University, who have developed a novel method to manufacture large quantities of high-quality, electrically conductive graphene that is both powerful and foldable. This new technique uses ethanol and ethyl cellulose to separate the graphene from cellulose, which is then printed using an ink-based process. The result is a highly conductive material ideal for advanced electronics, with conductivity boosted by 250 times compared to previous versions.
Graphene is widely recognized as one of the most conductive materials available, making it a perfect candidate for high-frequency circuits. These circuits are essential in modern electronics, especially as devices like smartphones require higher frequencies to handle more data efficiently. With this innovation, graphene can now be produced in larger quantities without sacrificing quality, opening up new possibilities for next-generation technology.
Beyond its electrical properties, graphene also offers exceptional strength, chemical stability, and flexibility—making it a highly sought-after material in the field of electronics and computing. However, producing pure, high-quality graphene on a large scale has long been a challenge. Until now, methods such as mechanical exfoliation or liquid solvent techniques resulted in either low-quality material or small batches that weren’t suitable for mass production.
Northwestern’s new method overcomes these limitations. By using ethanol and ethyl cellulose, they’ve created a scalable and efficient way to produce high-quality graphene sheets. Once mixed with ink, these sheets can be printed using standard inkjet printers, resulting in flexible circuits that maintain their performance even when bent or folded. The conductivity remains impressively high, at 250 times that of earlier graphene circuits.
This advancement could revolutionize the design of flexible and foldable electronics. Imagine a device that unfolds into a large display, much like a map, or wearable tech that integrates seamlessly into clothing rather than relying on rigid components. With this technology, the future of computing might look more like a flexible, adaptive system rather than a fixed, rigid structure.
