After several decades of intense researches on organic optoelectronics, several types of optoelectronic devices such as organic light-emitting devices (OLEDs) have become commercially viable and performance of organic photovoltaic (OPV) devices has seen significant progress. At the same time, scientists are getting better understanding on the device physics and the important roles of charge-transfer

The performance of Precious Group Metal-free (PGM-free) catalyst layers suffers from mass transport limitations due to the thickness required to achieve sufficiently high loading to match the performance of the Pt-based electrodes. A more detailed understanding of the PGM-free electrode structure is of a great importance to further improve their performance, but the nano-scale structure presents a

Two-dimensional transition metal carbides (nitrides) MXenes have excellent electrochemical properties and be hoped as a promising electrode material for supercapacitors. However, MXene nanosheets are prone to aggregate due to van der Waals interaction, which affect its electrochemical performance. In this study, nitrogen-doped Ti3C2 (N-Ti3C2), which hydrothermally prepared from MXene Ti3C2, was assembled
