Davide Zanetti, Cristian De Luca, and Davide Bonifazi discuss the resurgence of peri-xanthenoxanthene from a forgotten dye into a versatile organic semiconductor and sustainable photocatalyst, emphasizing its importance in photoredox catalysis.

The lanthanides comprise a series of 15 elements that have applications in many modern technologies, including magnetic materials and optics. Their chemistry has been traditionally dominated by the +II and +III oxidation states; higher oxidation states, except in the case of cerium, have long been deemed unreachable. Now, an example of a stable praseodymium complex in the formal oxidation state +V

The growing demand for fluorochemicals has increased the production of toxic hydrogen fluoride (HF)—a widely used fluorination agent—from mineral fluorspar (CaF2). Although potassium fluoride (KF) is a safer alternative fluorination agent, its production still involves HF as an intermediate. Simultaneously, the disposal of fluoropolymer waste, especially polyvinylidene fluoride (PVDF), poses environmental

Moses Dike and Shudipto Konika Dishari explore lignin’s historic journey alongside human civilization and showcase its game-changing potential to drive sustainability without compromising performance.

Modern scientists exist within the digital world. Shira Joudan describes how an online presence is beneficial to researchers, and what a baseline presence can look like.
