A series of porous organic polymers (POPs) were fabricated based on a boron dipyrromethene (BODIPY) core. The variation the substituents in BODIPY core and fine-tuning Sonogashira polycondenzation reaction with 1,3,5-triethynylbenzene led to formation POPs wide range surface area porosity. 10-fold increase from 73 m2 g-1 BDT1a polymer 1010 BDT3 was obtained. Simultaneously, porosity changed mesoporous ultramicroporous. turned out be highest reported so far for BODIPY-based POPs. Molecular...
Abstract In this research, a solvothermal approach is introduced to synthesize metal-organic frameworks (MOFs) nanocomposite (GO/UiO-66-NDC) for the removal of Cr(VI) from water. A comprehensive analysis was performed understand physical, chemical, and structural properties MOF nanocomposite. The adsorption behavior investigated by changing various parameters, such as pH, dosage, concentration, determine isotherms, thermodynamics, kinetics. results showed that had high tolerance pH thermal...
Tetraphenyl-5,5-dioctylcyclopentadiene based porous organic polymers were fabricated in the form of powder, soluble solvents and nanoparticles explored for gas adsorption chemosensing.
Abstract Conducting polymer ultrathin films with high absolute electromagnetic interference (EMI) shielding effectiveness (SE) is highly desirable for their facile processability. The conducting polymer, poly(3,4‐ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS), possesses excellent conductivity. However, a thin film of PEDOT:PSS water soluble, making it disadvantageous EMI shielding. Here, cross‐linked, water‐insoluble, evaluated. A 9 ± 1 µm thick cross‐linked exhibits an average...
In this work, the electromagnetic interference (EMI) shielding properties of an MXene interlayered crosslinked conducting poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate) (PEDOT:PSS) polymer film are investigated.
A novel series of benzimidazole-based molecules mimicking biological receptors, which exhibit selective coordination with zinc ions, were designed and synthesized. The photochromic behavior these derivatives various metal ions suggests a interaction one the receptors 2-(pyridin-2-yl)-4,7-di(thiophen-2-yl)-3H-benzo[d]imidazole (2c) ion. lower limit detection by photoluminescence quenching was determined to be 16 nM. mechanism complexation elucidated 1H nuclear magnetic resonance titrations...
The polymer composite-based microwave absorption material is highly valued in stealth technology, military, wireless self-powered devices, and telecommunication. In this work, characteristics of different compositions polyaniline (PANI)-Ti3C2Tx MXene (a family 2D material) hybrid loaded polyvinyl butyral (PVB), viz., the PVB-PANI-Ti3C2Tx nanocomposite, are explored with an electromagnetic data-driven approach. significance proposed approach that, through this, reflection loss (RL) (minimum...
Abstract Polyvinyl alcohol (PVA) is a great interest polymer due to its excellent film‐forming, emulsifying, microwave dielectrics and adhesive properties. However, PVA water‐soluble synthetic making it susceptible environmental factors. In this work, crosslinked at room temperature using divinyl sulfone (DVS) as crosslinker, the obtained (XPVA) water‐insoluble. Crosslinking mechanism proposed, thermal dielectric properties of X‐PVA are studied. The studies revealed that has better stability...
Phorate is a systemic insecticide used to eradicate mites, insects, and nematodes. Extensive use of this organophosphate has engendered severe environmental concerns. The current research aimed explore the kinetic pathways phorate biodegradation in aqueous solutions. Two novel bacterial strains Pseudomonas aeruginosa strain PR1 (KP268772.1) sp. PR_02 (KP268773.1) were isolated, screened, developed given their potential degrade phorate. Mineralization was assayed with without addition metal...
Functionalized carbon dots (CDs) derived from Citrobacter freundii bacterial cells were used for selective detection of Cr(VI). A microwave-heating-based green synthesis approach is adopted to produce functionalized CDs C. (CF-CDs). The reaction was carried out in a 500 W microwave digester at 200°C 20 min. supernatant filtered with 0.2 µm filter and highly monodisperse obtained. Inherent functionalization CF-CDs nitrogen oxygen-containing functional groups made them extremely toward Cr(VI)...
Engineered and managed wetland systems that are receiving increasing global attention for wastewater treatment reclamation. Compared to conventional plants, constructed wetlands inexpensive easy operate maintain, they have strong potential application in a small community. Constructed developed significantly recent decades. As an environmentally friendly method, can enable effective, economic ecological of agricultural, industrial municipal wastewater. Built-up very effective removing...
