Electrochemically Engineered PEDOT:PSS/MXene Composite Electrode for the Label‐Free Procalcitonin Detection

open access: yesAdvanced Materials Interfaces, EarlyView.
Procalcitonin is a key biomarker for bacterial infections, but conventional detection methods are often time‐consuming. Here, we present an electrochemical sensor based on highly conductive Ti3C2Tx MXene combined with PEDOT:PSS, enabling direct antibody immobilization, while a bovine serum albumin coating provides antifouling protection.

Topological Point Defects in SmC* Liquid Crystals Under Mechanical Disturbance

open access: yesAdvanced Materials Interfaces, EarlyView.
Tangetial air jet shear inducess island formation and nucleates topological point defects in uniform SmC films. Island bounded by edge dislocation loops shrink and transform into isolated point defects under continued shear. Mechanical perturbatio provides a controllable route for defect engineering in smectric liquid crystal thin films.

Adsorption of Thiophenic Compounds from n-Hexane Using Activated Carbon Adsorbent

open access: yesمجلة النهرين للعلوم الهندسية, 2015
The aim of this work is to study the adsorption of thiophenic compounds (thiophene and benzo thiophene) on activated carbon by studying the effects of various important variables such as height of the bed (4, 6, and 8 cm) , inlet sulfur concentration (50,

Mapping the perturbation potential of metallic and dipolar tips in tunneling spectroscopy on MoS2 [PDF]

open access: yes, 2019
Scanning tunneling spectroscopy requires the application of a potential difference between the sample and a tip. In metal-vacuum-metal junctions, one can safely assume that the potential is constant along the metallic substrate.

Chemically Doped Conductive Polymers for Wearable Health Monitoring

open access: yesAdvanced Materials Technologies, EarlyView.
Among conductive polymers, poly(3,4‐ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS), polyaniline (PANI), and polypyrrole (PPy) are the most studied and applied. Chemical doping significantly boosts intrinsic conductivity and mechanical robustness.

Pulling and Stretching a Molecular Wire to Tune its Conductance

open access: yes, 2015
A scanning tunnelling microscope is used to pull a polythiophene wire from a Au(111) surface while measuring the current traversing the junction. Abrupt current increases measured during the lifting procedure are associated to the detachment of molecular
