Abstract The demand for advanced energy storage devices such as supercapacitors and lithium‐ion batteries has been increasing to meet the application requirements of hybrid vehicles renewable systems. A major limitation state‐of‐art lies in their relatively low density compared with lithium although they have superior power cycle life.

Triplet exciton-based long-lived phosphorescence is severely limited by the thermal quenching at high temperature.

The achievement of significant photoluminescence (PL) in lanthanide ions (Ln3+ ) has primarily relied on host sensitization, where energy is transferred from the excited material to Ln3+ ions. However, this luminous mechanism involves only one optical antenna, namely material, which limits accessibility excitation wavelength-dependent (Ex-De) PL. Consequently, wider application light-emitting devices hindered. In study, we present an organic-inorganic compound, (DMA)4 LnCl7 (DMA+ =[CH3 NH2...
Abstract 2D conductive metal–organic frameworks (2D c ‐MOFs) as emerging graphene‐like crystalline materials have become a promising platform for energy storage.

Abstract A simple method was developed to prepare ultra‐low Pt loading membrane electrode assembly (MEA) using vertically aligned carbon nanotubes (VACNTs) as highly ordered catalyst support for PEM fuel cells application. In the method, VACNTs were directly grown on cheap household aluminum foil by plasma enhanced chemical vapor deposition (PECVD), Fe/Co bimetallic catalyst. By depositing a thin layer VACNTs/Al and subsequent hot pressing, Pt/VACNTs can be 100% transferred from Al onto...
