Summary: By adopting the AgI and conductive polymer assisted co-enhancement strategy, graphene fiber-based supercapacitors (GFSCs) with super-high energy density, favorable mechanical properties, and superior electrochemical properties were successfully prepared. The conductive binder polymer PEDOT enhanced the strength, conductivity, and electrochemical performance of RGO fibers, while the synergistic effect of micro- and nano-scale AgI and aqueous gel electrolyte widened the potential window of GFSCs and significantly increased their energy density. This work opens a new way to design and fabricate high-performance GFSCs.

Summary: In this study, poly(m-aminophenol) (PmAP) was used as a conductive supercapacitor binder to replace poly(vinylene difluoride) (PVDF). The advantages of using PmAP include its solubility in organic solvents, film-forming properties, and involvement in pseudocapacitive reactions. A ternary nanocomposite film consisting of vanadium pentoxide (V2O5), amino-functionalized graphene (amino-FG) and PmAP was fabricated and evaluated in different electrolytes, KCl and Li2SO4. The V2O5/amino-FG/PmAP nanocomposite showed improved pseudocapacitive performance and a 5-fold increase in specific capacitance compared to the V2O5/amino-FG/PVDF nanocomposite. Solid-state asymmetric supercapacitors (ASCs) using V2O5/amino-FG/PmAP film as the positive electrode exhibited high energy density in Li2SO4 electrolyte.

Summary: Metal halide perovskites have attracted significant interest in photovoltaics, but their toxic lead content and operational instability hinder commercialization. The strategy to overcome this is to replace lead while maintaining stability and efficiency. Halide double perovskites have emerged as lead-free alternatives with flexibility, lower toxicity, and higher stability. An analysis of these compounds reveals key factors influencing their solar cell performance and identifies strategies to enhance their photovoltaic properties.

Summary: There is growing interest in using metal halide perovskites for heterogeneous catalysis. In this study, a Ge-based 2D perovskite material with intrinsic water stability is presented by engineering the organic cation.

Summary: In the past decade, metal halide perovskite materials have shown great potential in optoelectronic technologies, especially in solar cells. However, challenges related to material processability and instability hinder the industrialization of these technologies. This review focuses on the incorporation of polymers as additives to control the crystallization process of perovskite materials in order to overcome these challenges and achieve reproducible manufacturing of robust films. The review discusses the recent advances in polymer inclusion in perovskite photoactive layers for solar cells, including the self-assembly process of metal halide perovskites and the use of polymers with different functionalities as templating agents for the growth of high-quality polycrystalline films. It also rationalizes the influence of polymers on stability, mechanical behavior, and processability of perovskite materials.

Summary: This study investigates the effects of fibre concentration on the mechanical response of welded glass-fibre-reinforced polypropylene (GF-PP). Experimental observations reveal a significant reduction in weld ratio, up to 60%, indicating a decreased strength compared to the bulk material. Increasing fibre content in the welded material results in a decrease in stress at break and strain at the maximum stress. The use of DIC technique and X-ray microtomography further confirms the localized strain amplification in the welded zone due to the significant increase in fibre density.

Summary: Real-time monitoring of carbon fibre composites during Automated Fibre Placement (AFP) manufacturing remains a challenge for non-destructive evaluation (NDE) techniques. This study designed a directional eddy-current (EC) probe to evaluate the detectability of out-of-plane wrinkles. Experimental evaluations and finite element modeling were conducted to better understand the relationship between eddy-current density and defect detection. The findings suggest that the probe configuration with an asymmetric driver coil and differential pickup coils shows the best capability for wrinkle detection.
