This study presents the electrochemical sensing of dopamine (DA) using an electrode polypyrrole/poly(3,4-ethylenedioxythiophene) (PEDOT-PPy) thin film. Electrochemical analyses PEDOT-PPy film for DA were conducted through cyclic voltammetry (CV) and differential pulse (DPV). The CV analysis demonstrated that exhibited superior activity towards due to its enhanced conductivity as a high-conducting polymer composite. DPV results indicated linear concentration level 5 nM 200 µM with minimal limit material. fabricated sensor explored sensitivity 7.27 µA/µM cm2 at 1000 diffusion coefficient 1.3 × 10–8 cm2/s. Additionally, material displayed excellent reproducibility, selectivity, stability. Therefore, composite shows potential outperforming other materials in detecting DA.

Abstract Pervious concrete (PC) has been widely employed in parking areas, residential streets, walkways, etc. because it allows water to run through at a rapid pace, thus reducing runoff from site and allowing groundwater recharge. The major hindrance utilizing PC for various applications is its lower compressive strength than conventional concrete. This work fillers such as chopped glass fibers (GFs), fiber mats, graphene oxide (GO) increase the of without compromising capability drain water. samples prepared by incorporating 0.375″ gravels exhibited maximum (5.01 MPa) while sample comprised 6 mm sized GF demonstrated ~1.7 times higher that with mats. Furthermore, GO loading 0.036 wt.% improved two compared neat altering flow rate PC.

Abstract With the development of aerospace and modern industry, demand for carbon fiber reinforced composites (CFRP) with both excellent electromagnetic shielding properties high mechanical became necessary. Herein, a novel modified CFRP multiscale hierarchical “rigid‐flexible” nanostructured interphase was constructed by feasible simple methods. Initially, “flexible” deposited polydopamine (PDA) “rigid” 2D MXene nanosheets were subsequently introduced on (CF) surface dip‐coating method, then 1D nickel (Ni) chains further CF spray coating approach. At last, epoxy prepared into related (CF‐PDA‐MXene‐Ni/EP) vacuum‐assisted resin transfer molding (VARTM) method. Results showed that tensile composite highly improved compared to those original CF/EP. The strength modulus could reach 542.80 MPa 7.30 GPa, which respectively 23.59% 23.94% higher than Meanwhile, failure modes changed from neat fracture shear breaking yarns. Moreover, EMI SE 68.88 dB, 7.07% composite. innovative design these kinds offered broad prospects next generation materials. Highlights Polydopamine, MXene, Ni fabrics. CF‐PDA‐MXene‐Ni/EP fabricated VARTM Electromagnetic shielding, as well behaviors composite, analyzed.

Abstract Functionalized thin films with excellent flexibility and conductivity can meet the current requirements for electromagnetic(EM) shielding materials. In this paper, 2D transitions metal carbide nitride nanomaterials Ti 3 C 2 T x MXene were prepared by chemical exfoliation, PVDF/MWCNTs/3 wt%/RGO@Fe O 4 @ AgNWs‐10 based on PVDF/MWCNTs‐3 @AgNWs‐10, The samples through a simple solution mixing process followed vacuum‐assisted filtration (VAF), PVDF/MWCNTs/MXene/RGO@Fe @AgNWs three‐layer PVDF‐based composite films, which analyzed electrical EM properties, increased then decreased rise in content, highest of M3/MX‐10/R@F@Ag was obtained when addition amount reached 10 mL as 3.9 × S/m, EMI SE is 54.9 dB, A 44.8 absorption loss 81.6%, SSEt film 1672.5 dB/(cm −2 ·g).
