Author | Sensor Technology (WW_CGQJS) In 1888, Austrian botanist Friedrich Reinitzer discovered liquid crystals, a peculiar organic compound that has two melting points. When heated to 145°C, its solid crystalline state melts into a cloudy liquid, while pure substances typically become transparent when melted. If heated further to 175°C, it appears to melt again, turning … Read more

One advantage of UEFI is its modularity, meaning you can write a module that, once compiled, can be inserted into an existing BIOS and executed. Previously, the implementation methods of each IBV varied greatly, and there was almost no way to achieve universality except for inserting in a special form like PCI ROM. The demonstration … Read more
