Novel 2D Ti3C2Tx (MXene)-reinforced polyvinyl alcohol (PVA) nanofibers have been successfully fabricated by an electrospinning technique. The high aspect ratio, hydrophilic surfaces, and metallic conductivity of delaminated MXene nanosheet render it promising nanofiller for performance nanocomposites. Cellulose nanocrystals (CNC) were used to improve the mechanical properties nanofibers. obtained electrospun had diameter from 174 194 nm depending on ratio between PVA, CNC MXene. Dynamic...
Graphite and numerous graphitic-derived micro- nano-particles have gained importance in current materials science research. These two-dimensional sheets of sp(2)-hybridized carbon atoms remarkably influence the properties polymers. Graphene mono-layers, graphene oxides, graphite exfoliated graphite, other related are derived from a parental structure. In this review, we focus primarily on role these fillers regulating electrical sensing polymer composites. It has been demonstrated that...
A new method for the simple synthesis of stable heterostructured biopolymer (sodium alginate)-capped silver nanoparticles (Ag-NPs) based on green chemistry is reported. The as-prepared were characterized using ultraviolet-visible (UV-Vis) absorption spectroscopy, X-ray diffraction (XRD), transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FTIR), and dynamic light scattering (DLS) techniques. results showed that Ag-NPs have a morphology with particle size in range...
Abstract Background Carbon dots (CDs) are of particular interest in numerous applications. However, their efficiency for heavy metal removal from wastewater was not yet reported. Herein, we rationally synthesized CDs petroleum coke waste via hydrothermal treatment the presence ammonia. Results This drove formation outstanding photoluminescent, water-soluble, biocompatible, and high yield monodispersed sub-5 nm CDs. The co-doped with 10% N 0.2% S. as-prepared possess unprecedented...
Abstract Boron is an essential micronutrient that has raised much interest, given the narrow balance between its necessity and toxicity. Both natural anthropogenic emissions of boron into water sources can eventually deteriorate quality endanger ecosystem. In this review, we first present a general outline importance boron, chemistry in water, contamination, consequences followed by recent progress removal methods based on adsorption. The adsorbents for deboronation generally be classified...
In this work, graphene quantum dots (GQDs) were prepared from Graphitic waste. The resulting GQDs evaluated for the potential application resistive humidity sensors. sensors fabricated on pre-patterned interdigital ITO electrodes using three different concentrations (2.5, 5.0, and 10 mg) of in DMF. films deposited spin coating technique. (10 mg/ml) based impedance showed good sensitivity lowered hysteresis as compared to other ratios (2.5 5 GQDs. maximum calculated sensor is around 2.2 % at...
The electrically conductive, transparent, and flexible self-standing thin nanocomposite films based on copolyamide matrix (coPA:Vestamelt X1010) modified with 2D Ti3C2Tx (MXene) nanosheets were prepared by casting their electrical, mechanical optical properties then, investigated. percolation threshold of the MXene filler within coPA was found to be 0.05 vol. %, highest determined electrical conductivity 1.4 × 10-2 S·cm-1 for composite filled 5 wt. % (1.8 %) MXene. as-prepared 9.1 S·cm-1,...
The extensive utilization of phase change materials (PCMs) for thermal energy harvesting, storage, and management is often constrained by their inadequate electrical conductivity, form instability, lack photoabsorbance. To overcome these challenges, a composite was prepared vacuum infiltration paraffin wax (PW) into highly conductive scaffold graphite panel (GP). Various PW grades with different temperatures were tested to study suitability wide range applications. Graphite-based skeleton...
Thermal management of photovoltaic (PV) panels is crucial due to the deterioration their electrical efficiency at elevated operating temperatures. Therefore, thermal protection PV against overheating highly required. This study investigated applicability shape-stabilized phase change material (PCM) composites for temperature regulation modules (PVM). Paraffin waxes (PW) with specific melting temperatures infiltrate graphite foam (GF) prepare GF_PW composite. The PCM are coated expanded...
