Synthesis of polyaniline/TiO2 nanocomposites: effects of acid and aniline concentrations on material properties and photocatalytic performance for sulfamethoxazole degradation

open access: yesJournal of Chemical Technology &Biotechnology, Volume 101, Issue 9, Page 1906-1923, September 2026.
Abstract BACKGROUND This work investigated the synthesis of TiO2‐P25/polyaniline (PANI) nanocomposites, denoted as PANI– TiO2, via chemical oxidative polymerization under different aniline:H+ molar ratios, and evaluated their performance in heterogeneous photocatalysis (HP).

Molecularly Mediated Assembly of Metal Nanoparticles With Multifunctional Interfaces for Selective Detection of Small Gas Molecules

open access: yesSmall, Volume 22, Issue 52, 16 September 2026.
This work demonstrates a conceptual framework of three types of cooperative interaction pathways in molecularly assembled nanoparticle chemiresistors. Their relative contributions depend on nanoparticle composition, linker chemistry, film architecture, and analyte identity, modulating the effective tunneling barrier (Φ), interparticle spacing (d), and ...

Interfacial Defect Passivation by Molecular Dipole‐Moment Engineering in Perovskite Solar Cells

open access: yesSmall Science, Volume 6, Issue 9, September 2026.
A bulky cation material with a dipole moment, 4‐MeO‐PEABr, is applied to improve interfacial contact and passivate the defects of perovskite films. The molecular dipole moment of the molecule affects the work function of the perovskite film, yielding an efficiency of 22.7% (SPO at 22.5%), and improved performance retention under illumination.

Phosphoric Acid–Modified TiO2 Nanoparticles as Functional Additives for High‐Performance Polyethersulfone Ultrafiltration Membranes

open access: yesWater Environment Research, Volume 98, Issue 9, September 2026.
Phosphoric acid–modified TiO2 nanoparticles significantly enhance the performance of polyethersulfone ultrafiltration membranes by improving hydrophilicity, permeability, and antifouling resistance. The surface‐functionalized nanoparticles promote stable dispersion and favorable membrane morphology, resulting in superior separation efficiency and long ...

Thin film pyroelectric array as a detector for an infrared gas spectrometer

open access: yes
We demonstrate the implementation of a thin film pyroelectric array as a detector in an infrared gas spectrometer. The 1 x 50 element array is integrated onto a silicon chip with a sol-gel deposited zirconium modified lead titanate film (PZT) as the ...
