WebJul 29, 2011 · Boron compounds normally are acids that accept electron pairs, but Kinjo et al. show how to stabilize an electron pair on a boron center so that it forms a base—a borylene compound. The parent borylene A (R = H) is linear and sp-hybridized, and the lone pair is in an sp orbital. It accepts two electron pairs from two carbenes, yielding a … WebApr 27, 2024 · Thus, this process cannot generate enough corresponding electron–hole pairs in the semiconducting materials due to the low diffusion length of Li atoms and alpha ions [28,29]. Other candidates such as B 4 C and pyrolytic boron nitride-based detectors are still suffering design issues and low detection efficiency .
