Article Abstract
A novel gas ionization sensor using Pd nanoparticle-capped ZnO (Pd/ZnO) nanorods as the anode is proposed. The Pd/ZnO nanorod-based sensors, compared with the bare ZnO nanorod, show lower breakdown voltage for the detected gases with good sensitivity and selectivity. Moreover, the sensors exhibit stable performance after more than 200 tests for both inert and active gases. The simple, low-cost, Pd/ZnO nanorod-based field-ionization gas sensors presented in this study have potential applications in the field of gas sensor devices.

Hard carbon has emerged as the most widely studied and commercialized anode material for sodium-ion batteries (SIBs). However, improving the charge transfer kinetics within the plateau potential range of the hard carbon anode is crucial for the development of fast-charging SIBs. In this study, we prepared a novel composite material, ZAPA-1300, by uniformly mixing starch, asphalt, and zinc oxide (ZnO), followed by a two-step treatment process.

Nowadays, the recovery of valuable metals from waste mobile phone printed circuit boards (WMPCBs) has attracted significant attention from researchers due to their economic potential. However, improper recycling poses serious risks to both human health and the environment. This study introduces, for the first time, a deep eutectic solvent (DES) as a novel, green, and highly selective carrier within an emulsion liquid membrane (ELM) system for the recovery of gold (Au) from WMPCBs.

The soil in reclaimed shale gas sites is compacted and suffers from issues like poor drainage, drought conditions, and nutrient deficiency, posing challenges for agricultural production. In this study, rare earth tailings were incorporated into biochar at different mass ratios (rare earth tailings: biochar = 1:1, 1:2, 1:3, 1:4). Subsequently, a series of rare earth tailings-doped biochar materials (REE-BC) were prepared by calcination at 700°C.
