Polyaniline-Poly (o-methoxyaniline) composite films as supports of Pt-Ru nanoparticles for formic acid electro-oxidation

open access: yesInternational Journal of Electrochemical Science, 2014
Polyaniline-Poly (o-methoxyaniline) (PANI-POMAN) composites are synthesized using cyclic voltammetry (CV) methods. Platinum (Pt) and Ruthenium (Ru) bimetal nanoparticles are co-deposited onto the PANI-POMAN film to produce a durable and efficient electro-

Infrared Spectroscopic Predictions of Soil Properties for Agricultural Monitoring: Statistical and Soil Spectroscopic Considerations

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background: Pseudo‐independent validation (PIV) using regional datasets is common in visible‐to‐near‐infrared (vis–NIR) and mid‐infrared (MIR) spectroscopy studies and produces accurate predictions but is relevant only to regional‐scale monitoring of known sites.

PLS-regression : a basic tool of chemometrics

open access: yes, 2001
PLS-regression (PLSR) is the PLS approach in its simplest, and in chemistry and technology, most used form (two-block predictive PLS). PLSR is a method for relating two data matrices, X and Y, by a linear multivariate model, but goes beyond traditional ...

Robust Spectroscopic Analysis Through Image‐Based Spectral Representation and Deep Learning Techniques

open access: yesJournal of Raman Spectroscopy, EarlyView.
This study addresses calibration drift in Raman spectroscopy by transforming 1D spectra into 2D spider plot images processed by pretrained convolutional neural networks. This visualization strategy effectively converts detrimental spectral wavenumber shifts into simple image rotations, allowing the deep learning model to maintain high classification ...

Development of an interfering peptide M1-20 with potent anti-cancer effects by targeting FOXM1

open access: yesCell Death and Disease, 2023
Disrupting protein–protein interactions (PPIs) has emerged as a promising strategy for cancer drug development. Interfering peptides disrupting PPIs can be rationally designed based on the structures of natural sequences mediating these interactions ...
