Summary: In this paper, two methods for improving the field emission performance of carbon nanotube emitters are presented and compared. The treatments with dimethyl sulfoxide (DMSO) solution and poly(3,4-ethylene dioxythiophene):polystyrene sulfonate (PEDOT:PSS) solution both reduced the threshold electric field and improved the efficiency and lifetime of the CNT emitters. However, the treatment with PEDOT:PSS solution showed more significant improvements. The study demonstrates that these simple treatment methods greatly enhance the lifetime of field emission and make them suitable for large currents and long-term use.

Summary: It is challenging to reduce the noble-metal loading in oxygen evolution reaction (OER) catalysts while maintaining their catalytic performance. This study introduces a highly active OER catalyst, IrO2@Ir/TiN, composed of IrO2 with Ir rich surface nanoparticles supported over nano TiN coated with TiOxNy. The catalyst exhibits superior OER performance with small, uniformly dispersed IrO2@Ir nanoparticles and high durability due to robust catalyst support and strong catalyst-support interaction. The synthesized IrO2@Ir/TiN catalyst with 40 wt % Ir loading shows a mass-normalized OER activity of 637 Ag-Ir(-1), which is 2.4 times higher than that of the commercial benchmark IrO2 OER electrocatalyst. The catalyst also demonstrates excellent durability (79 % retention) compared to the commercial equivalent (66 % retention) during an accelerated stress test.
