Multi‐Walled Carbon Nanotube‐Modified Carbon Paste Electrode for Fipronil Detection in Environmental Samples

open access: yesElectroanalysis, Volume 37, Issue 7, July 2025.
A nanostructured carbon paste sensor modified with 20% multi‐walled carbon nanotubes (MWCNTs) was developed for the detection of Fipronil. The sensor showed enhanced electrochemical performance, with a limit of detection of 0.377 µmol L‐1. It demonstrated good stability, selectivity, and high recovery in water samples, highlighting the potential of ...

Mathematical Modeling To Estimate The Growth Of Guandu Bean Pods And Seeds

open access: yesBrazilian Journal of Experimental Design, Data Analysis and Inferential Statistics, 2022
The objective of this study was to adjust mathematical equations that accurately and non-destructively estimate the growth of pods and seeds of pigeon pea cultivar Fava Larga from the average length and width. For this, the maximum width (W), maximum length (L), and observed mass (OM) of pods and seeds were measured.
