In this study, we investigate the thermoelectric properties of functionalized multi-walled carbon nanotubes (F-MWCNTs) dispersed over a flexible substrate through a facile vacuum filtration route. To improve their interfacial adhesion and dispersion, F-MWCNTs underwent hot-pressing. The heat-treatment has improved the nanotubes' connections and subsequently reduced porosity as well, which results in an increasing electrical conductivity upon increasing temperature of hot-pressing.

Influence of terminal moiety on PCE of DSSCs: An In Silico study based on triazatruxene-benzothiadiazole dye.

Spectrochim Acta A Mol Biomol Spectrosc

February 2025

Department of Chemistry, COMSATS University, Abbottabad Campus, Abbottabad 22060, Pakistan. Electronic address:

Our study utilized an experimentally synthesized dye as a reference molecule, employing a donor-π linker-acceptor (D-π-A) framework for organic solar cells. The molecule featured a triazatruxene group linked with alkyl branches as the donor and ethynyl benzoic acid as the acceptor, connected through a derivative of benzothiadiazole as the π linker. To improve optoelectronic and photovoltaic properties, ten theoretically designed dyes (ZA1-ZA10) are proposed, differing from the reference (R) by modifying the terminal acceptor moiety.

  • - The study examined how over-fertilizing fish ponds with various fertilizers (NPK, TSP, DAP) leads to increased levels of heavy metals (Pb, Cu, Cd, Cr) in water, sediment, and fish species, particularly noting that DAP caused the highest metal concentrations.
  • - Heavy metal levels were significantly higher in fertilizer-applied groups compared to a control group, with DAP showing the most pronounced effects; however, the health index for fish muscles remained safe for consumption.
  • - The researchers emphasize the need for careful monitoring and regulation of fertilizer use, especially DAP, to prevent contamination and recommend exploring sustainable farming practices to reduce environmental health risks.
