Summary: An innovative one-pot electrochemical method has been studied for the synthesis of PPy-Cu composite films as the active layer of ReRAM. Cu is uniformly distributed in the films and exhibits two valence states of Cu (0) and Cu (II). The presence of Cu (II) is beneficial for maintaining stable resistive switching performance. The Pt/PPy-Cu/Pt ReRAM device shows excellent memory performance with a low threshold voltage, a long retention time, and good endurance cycles. The resistive switching mechanism is mainly dominated by the Space Charge Limited Current (SCLC) effect accompanied by Schottky emission.

Summary: Electrochromism is the ability of a material to change its optical properties or color when an external potential is applied. Conventional electrochromic materials based on inorganic materials have drawbacks including single color change, expensive materials, and slow switching speed. To overcome these challenges, conducting polymers (CPs) have emerged as a promising alternative with advantages of multicolor, fast response, low cost, easy processing, and environmental friendliness. This review introduces the current state-of-the-art development of ECDs based on three popular CPs, namely, polyaniline, polypyrrole, and poly(3,4-ethylenedioxythiophene) polystyrene sulfonate, with emphasis on their synthetic approaches and electrochromic performance.

Summary: In this study, a Ppy-PMB heterostructure was electrochemically formed on ITO-coated glass slides, and the effect of different saccharides on its electrochromic properties was compared. AFM and SEM were used to analyze the surface features of the Ppy-PMB layers, revealing a moderate effect of the saccharides on surface morphology. The electrochromic properties were analyzed by measuring absorbance changes at different wavelengths and pH values, showing the highest absorbance changes in acidic media. The Ppy-PMB layers doped with heparin exhibited higher mechanical stability compared to layers doped with lactose and sucrose. The heparin-doped Ppy-PMB layer was selected for further experiments and applied in the design of an electrochromic sensor for the determination of three xanthine derivatives.

Summary: The study found that heparin and bivalirudin have different and complementary inhibitory effects on the activation of PAR1 and PAR4 by thrombin. Heparin inhibits PAR4-mediated platelet activation, while bivalirudin inhibits signaling from both receptors but leads to delayed PAR4-mediated platelet activation, resulting in a strong prothrombotic response.

Summary: Conducting polymers, particularly polypyrrole, were used for surface modification of three different leathers. The polymer was deposited on collagen fibers, forming a thin layer with thickness ranging from 24 to 200 μm. The modified leathers showed changes in mechanical properties and sheet resistances, and their conductivity and electroactivity can potentially be utilized in intelligent leathers for footwear, heating elements, and energy storage.

Summary: Previous studies have shown that vibration- or rotation-based techniques can effectively mitigate fouling during membrane filtration. However, it is difficult to incorporate these techniques with spiral wound modules (SWMs) widely used in water and wastewater treatment. This study developed a prototype membrane system to accommodate angular vibrations with a modified SWM, and experimental results showed that applying angular vibrations can effectively control algal fouling in an SWM with lower energy consumption compared to traditional methods.

Summary: Increasing temperatures worldwide pose a significant health risk, exacerbated by high humidity. Conventional air conditioners contribute heavily to carbon dioxide emissions, with dehumidification being a major factor. Membrane-based dehumidification system offers energy efficiency and non-toxic water vapor removal. This study demonstrates a membrane dehumidification system with polymeric hollow fibers coated with a green polyphenol coating, showing remarkable water vapor transport rate and selectivity. Long-term testing reveals minimal decline in vapor transport and a 4-5 times higher coefficient of performance (COP) compared to conventional dehumidifiers, making it a highly competitive, energy-saving device with reduced emissions and a smaller footprint.
