Stevia byproducts as biomass-derived pore-forming additives for porous Hanji composites: Microstructure and property relationships

Seung Geun Kim, Seok Won Im, Young Chul Choi, Byung-Joo Kim et autres

This study investigated the structural, mechanical, air permeability, and thermal properties of porous traditional Korean paper (Hanji) composite sheets containing stevia byproducts. Stevia byproducts were incorporated into Hanji fiber networks as biomass-derived additives, and their effects on thickness, bulk, tensile properties, Gurley …

Tungsten-based ternary catalysts for selective growth of single-walled carbon nanotubes

jaehun hwang, Geon Han, YoongSoo Park, Sang Won Lee et autres

Single-walled carbon nanotubes (SWCNTs) with controlled diameters ranging from 1.5 to 3 nm were synthesized through a supported catalytic chemical vapor deposition (CCVD) process using an Fe-Mo-W ternary catalyst system. Tungsten in the ternary catalyst played a crucial role in maintaining catalyst …

Role of Nanoscale Morphology on the Efficiency of Solvent-Based Desalination Method

James S. Peerless, Alexey V. Gulyuk, Nina J. B. Milliken, Gyu Dong Kim et autres

Brine desalination is important for minimizing the environmental impact of contaminated wastewater, yet current desalination techniques have high energy requirements. Solvent-based desalination (SBD) method, which is the process of extracting fresh water using an organic solvent, has existed for decades, yet has …

Highly conductive quasi-defect-free reduced graphene oxide for qualitative scalable production

Sooyeon Jeong, Sunhye Yang, Byeong Guk Kim, Hyejung Lee et autres

Herein, we present a potential approach for the qualitative production of quasi-defect-free reduced graphene oxide (QrGO) with semimetallic transport behavior. In rGO, the formation of defects is highly dependent on the oxidation process of graphite. Subsequent exfoliation of graphite oxide, the quasi-defect-free …
