Conjugated Polymers with Self ‐Immolative Sidechain Linkers for Carbon Nanotube Dispersion
Single-walled carbon nanotubes (SWNTs) are selectively dispersed with a novel poly(fluorene-co-phenylene) having a self-immolative linker within its sidechains. Cleavage of the linker causes rapid removal of the sidechains, allowing the SWNTs to closely contact one another. Within a thin film, this led to an immediate 60-fold increase in conductivity, opening new possibilities for producing high-conductivity SWNT materials for numerous applications. AbstractSingle-walled carbon nanotubes (SWNTs) are promising materials for generating high-performance electronic devices. However, these applications are greatly restricted by...

Fluoride leaching from tuff breccia and its removal by natural and commercial adsorbents
Chemosphere. 2024 Mar 16:141735. doi: 10.1016/j.chemosphere.2024.141735. Online ahead of print.ABSTRACTIn Japan, the concentration of fluoride (F-) leached from rocks, such as tuff breccia, excavated in tunnel construction projects often exceeds the Japanese environmental standard of 0.8 mg/L. Because of this, proper disposal methods are necessary for managing F--bearing excavated rocks. One effective solution based on circular economy is the use of an adsorption layer system. This system can simultaneously prevent the migration of F- released from excavated rocks and allow the recycling of this construction waste material...

Online ahead of print.ABSTRACTExtracting heavy metal ions from wastewater has significant implications for both environmental remediation and resource preservation. However, the conventional adsorbents still suffer from incomplete ion removal and low utilization efficiency of the recovered metals. Herein, we present an extraction and reutilization method assisted by porous boron nitride (p-BN) containing high-density N atoms for metal recovery with simultaneous catalyst formation. The p-BN exhibits stable and efficient metal adsorption performance, pa...

Effect of adding CPP-ACP into a daily-use toothpaste on remineralization of enamel white spot lesions
Conclusions: CPP-ACP can serve as a suitable alternative to fluoride in daily-use toothpaste for enamel remineralization. The concurrent use of fluoride and CPP-ACP in toothpaste can generate a synergistic remineralizing effect at the enamel surface layer. (Source: Journal of Dental Materials and Techniques)
