Metal–Organic Framework (UiO-66)-Based Pesticide Delivery System for Effective Deltamethrin Loading and Sustained Pesticide Release

Wan, Minghui; Song, Saijie; Feng, Wenli; Wang, Xiaoyuan; Shen, Jian

2023 ACS Applied Engineering Materials

doi:10.1021/acsaenm.2c00105

A pesticide delivery system (PDS) is an effective strategy to overcome the low efficiency of conventional pesticide formulations. UiO-66, a metal–organic framework (MOF), is a suitable nanocarrier for pesticide delivery due to its large surface area, good stability, and nontoxicity. In this...

Synergistic Effect of Electrocatalytic Characteristics of a Redox Segment and Gas Barrier of rGO to Significantly Replace the Loading of Zinc Dust in Solvent-Based Epoxy Composites Applied for Heavy-Duty Anticorrosion Coatings

Lan, Yun-Xiang; Hu, Kai-Wen; Yan, Minsi; Liu, Wei-Ren; Wong, Wei-Tsan;

2023 ACS Applied Engineering Materials

doi:10.1021/acsaenm.2c00252

Zinc-rich epoxy coating plays a major role in current heavy-duty corrosion protection solutions, yet high loading of zinc dust (ZD) weakens the coating flexibility and adhesion capability of the overall coating. This work demonstrated the successful incorporation of small amounts of rGO and...

Fe–Nb Co-Doped Rutile TiO2 for Anode Materials of Li-Ion Batteries

Usui, Hiroyuki; Domi, Yasuhiro; Nguyen, Thi Hay; Sadamori, Yuma; Tanaka, Toshiyuki;

2023 ACS Applied Engineering Materials

doi:10.1021/acsaenm.2c00262

We attempted to improve electrochemical performances of a rutile TiO2 electrode as a Li-ion battery anode by doping with two kinds of elements with different ionic sizes. When Nb5+ and Fe3+ were doped into TiO2, the total doping amount could be increased up to 11 at.% because the doping amounts...

An Atomistic Insight into Moiré Reconstruction in Twisted Bilayer Graphene beyond the Magic Angle

Dey, Aditya; Chowdhury, Shoieb Ahmed; Peña, Tara; Singh, Sobhit; Wu, Stephen M.;

2023 ACS Applied Engineering Materials

doi:10.1021/acsaenm.2c00259

Twisted bilayer graphene exhibits electronic properties strongly correlated with the size and arrangement of moiré patterns. While rigid rotation of the two graphene layers results in a moiré interference pattern, local rearrangements of atoms due to interlayer van der Waals interactions...

Construction of Pt/Powder Charcoal Electrocatalyst Utilizing MnO2 as an Additive to Improve the Stability for Oxygen Reduction Reaction

Wang, Ziyu; Jin, Xuekun; Chen, Fengjuan; Bian, Shiya; Li, Junhua;

2023 ACS Applied Engineering Materials

doi:10.1021/acsaenm.3c00002

Pt/C catalyst is a crucial cathode material in proton exchange membrane fuel cells (PEMFCs), but its low stability limits its use in fuel cells. In this study, smaller Pt nanoparticles (NPs) were strongly anchored to the surface of regenerated decolorizing powder charcoal (PC) using MnO2 as an...
