Solvent-induced textured structure and improved crystallinity for high performance perovskite solar cells
We demonstrate an environment-friendly solvent treatment that leads to a dramatic performance improvement of perovskite solar cells, with power conversion efficiency as high as 18%, with good stability. The solvent not only improves perovskite film morphology and crystallinity, but also, at proper growth conditions, leads to the formation of a self-induced textured structure on a dense layer; th...

A Simple Method for High-Performance, Solution-Processed, Amorphous ZrO2 Gate Insulator TFT with a High Concentration Precursor
Solution-processed high-k dielectric TFTs attract much attention since they cost relatively little and have a simple fabrication process. However, it is still a challenge to reduce the leakage of the current density of solution-processed dielectric TFTs. Here, a simple solution method is presented towards enhanced performance of ZrO2 films by intentionally increasing the concentration of precurs...

High performance organic nonvolatile memory transistors based on HfO2 and poly(alpha-methylstyrene) electret hybrid charge-trapping layers
In this work, we fabricated a high performance flash-type organic nonvolatile memory transistor, which adopted polymer-electret poly(a-methylstyrene) (PaMS) and HfO2 films as hybrid charge trapping layer (CTL). Compared with a single HfO2 or PaMS CTL structure, the hybrid HfO2/PaMS CTL structure can provide enhanced charge trapping efficiency to increase the device operation speed and reduce the...

Ultrafine TiO2 Nanoparticles Confined in N-Doped Porous Carbon Networks as Anodes of High-Performance Sodium-Ion Batteries
TiO2-based nanocomposites with rationally designed size, structure, and composition are highly desirable for Na-ion storage. In this work, various TiO2/N-doped porous carbon nanocomposites (TiO2/NC) have been fabricated by directly carbonizing NH2-MIL-125(Ti) at different temperatures. These TiO2/NC nanocomposites exhibit unique structure features, such as ultrafine TiO2 nanoparticles, micro-mesop...

Porous Carbon Polyhedrons with High-Level Nitrogen-Doping for High-Performance Sodium-Ion Battery Anodes
Sodium-ion batteries have been regarded as probable alternatives to lithium-ion batteries in the field of large-scale energy storage. In this work, nitrogen-doped porous carbon (NPC) polyhedrons are fabricated by using nitrogen-containing metal-organic frameworks as novel templates and precursors. The resultant NPC materials exhibit unique structure features, including porous structure, high-level...

Effects of Hydrocarbon and Water Impurities on CO2/CH4 Separation Performance of Ester-crosslinked Hollow Fiber Membranes
High-performance ester-crosslinked hollow fiber membranes were evaluated for sensitivity to aggressive hydrocarbon and water impurities. The hollow fiber samples show improved separation productivity and hydrocarbon-induced antiplasticization resistance under extremely challenging feed conditions in comparison to previously reported cases. The CO2 permeance was improved from 10 GPU to 50 GPU with ...

JMS-Tailoring nanofiltration membrane performance for highly-efficient antibiotics removal by mussel-inspired modification
For efficiently sieving active molecules to concentrate/purify antibiotics, the pores of novel hydrophilic
polyethylene glycol (PEG) based nanofiltration (NF) membrane should be finely tailored. Herein, an effective coating layer is successfully built on the PEG based NF membrane through self-polymerization of
mussel-inspired dopamine (DA) which is confirmed by various physicochemical char...
