Cairo: The 2D Graphics Drawing Tool in C Language

Hello everyone! Today I want to introduce you to a super powerful C graphics library – Cairo. It is not only the cornerstone of the graphics systems in Linux and macOS, but also used in the rendering engines of browsers like Firefox and Chrome. Whether drawing simple lines and shapes, or creating complex user interfaces, … Read more

Regulating Oxygen Vacancy Concentration Activates Inert 2D Bi₂O₃ Nanosheets for Efficient HER

The oxygen vacancy (Vo) is closely related to the activity of hydrogen evolution reaction (HER) in electrocatalysts. However, the role of vacancy defects and their concentration effects remain unclear. Here, we selected Bi₂O₃ as a model, which is an unfavorable electrocatalyst for HER due to its non-ideal Gibbs free energy of hydrogen adsorption (ΔGₕ), to … Read more
