Summary: Conjugated conductive polymers are widely used in organic electronics, while non-conjugated polymers are mainly used as insulation materials or for capacitors. However, non-conjugated polymers have a wider potential for creating electronic materials with unique properties. This article demonstrates the creation of electrically conductive materials based on non-conjugated polymers and explores their practical applications. The study shows that abnormal electronic properties can be achieved along the interface of polymer dielectrics with functional polar groups.

Summary: One of the challenges for blind individuals to achieve optimal mobility is detecting and avoiding obstacles. The eBAT (electronic Buzzer for Autonomous Travel) is a mobile aid that interacts with a user's phone to provide protection and convenience. A usage test was conducted with 25 blind individuals, and the results showed that although the eBAT reduced involuntary contacts, it also decreased walking speed. There were some differences in performance based on sex, age, and mobility, but the statistical significance was limited, and there were also correlations between variables.

Summary: Redox-active MIP-Gly NPs were developed by incorporating ferrocenylmethyl methacrylate into the synthesis process, enabling them to selectively determine glyphosate without the need for redox probe. MIP-Gly NPs synthesized using allylamine and squaramide-based monomers exhibited the highest selectivity. The MIP-Gly NPs modified Pt-SPEs were characterized using differential pulse voltammetry and electrochemical impedance spectroscopy, with changes in the oxidation peak of the ferrocenyl moieties serving as the analytical signal. The chemosensor showed a low limit of detection and a wide linear dynamic concentration range for glyphosate, allowing successful detection in spiked river water samples.

Summary: Electrothermal processes were investigated in pyroresistive composites of high-density polyethylene with carbon black and carbon fibers. The kinetic heating curves showed an exponential dependence with a heating rate constant for each composite. Equilibrium temperature was reached after a short heating time, and decreased with the presence of positive temperature coefficient of resistance (PTC) effect. The composites exhibited self-regulating capability and the equilibrium temperature depended on the applied voltage and electric power with different relationships. An application of using HDPE-CB composite as a heating element for resistance welding was demonstrated.
