Naphthalene diimide–bithiophene P(NDI2OD-T2) is a well-known donor–acceptor polymer, previously explored as n-type material in all-polymer solar cells (all-PSCs) and organic field effect transistor (OFETs) applications. The optical, bulk, electrochemical, semiconducting properties of polymer were tuned via random incorporation perylene diimide (PDI) coacceptor with naphthalene (NDI). Three copolymers containing 2,2′-bithiophene donor unit varying compositions (NDI) (xPDI, x = 15, 30, 50 mol...
Solution-processed high-performing ambipolar organic phototransistors (OPTs) can enable low-cost integrated circuits. Here, a heteroatom engineering approach to modify the electron affinity of low band gap diketopyrrolopyrole (DPP) co-polymer, resulting in well-balanced charge transport, more preferential edge-on orientation and higher crystallinity, is demonstrated. Changing comonomer from sulfur (benzothiadiazole (BT)) oxygen (benzooxadiazole (BO)) leads an increased introduces...
Conjugated donor–acceptor copolymers based on naphthalene diimide (NDI) as acceptor and thiophene-terminated oligophenylenevinylene donor moieties (P1 P2, respectively) were synthesized using the direct (hetero) arylation (DHAP) polymerization route. Nitrile groups introduced at vinylene linkage in one copolymer (P2) to fine-tune its electrochemical properties. Both polymers show π–π* transition 300–480 nm region intramolecular charge transfer (ICT) from thiophene NDI 500–800 absorption...
This paper reports a non-contact, in-situ and non-destructive corrosion monitoring methodology for submerged plates using ultrasonic guided waves. Specific surface sensitive core wave modes are utilized undergoing accelerated impressed current in the presence of chlorides. A combination selected could effectively discern various mechanisms occurring plates. Along with signals, mass loss, stress–strain behaviour tensile strength at different stages have been monitored. Algebraic relationships...
Donor–acceptor pi-conjugated polymers are emerging as interesting electrode materials for supercapacitor device applications. They offer an exciting possibility of charge storage in both positive and negative electrodes because they p- n-dopable. The ambipolar charging enables higher operating voltage, which can afford specific energy power densities. donor–acceptor design be either donor-alternate-acceptor or donor-random-acceptor. This architectural variation has the potential to modify...
Abstract The photocatalytic decolorization and mineralization of Reactive Black 5 (RB5) dye in presence TiO 2 Degussa P25 has been studied using artificial light radiation a shallow pond slurry reactor. equilibrium adsorption dye, influence pH (3–11), catalyst load (0.5–3.0 g/L), concentration (20–100 mg/L) on kinetics were studied. effect area to volume ratio photoreactor also Mineralization studies performed at optimized conditions (3) (1.5 g/L). maximum (26.5 mg/g) was found occur 3....

Abstract Industrial effluents contain a number of dyes. In order to understand photocatalytic treatment in such conditions, there is need study mixture Present paper compares the adsorption isotherms, and decolorization two anionic dyes Reactive Red 120 (RR120) Black 5 (RB5) single dye solution that their mixture. Both show adherence Langmuir isotherms solution. Adsorption characteristics RB5 are strongly affected presence RR120 studies. There seems be competition for sites on catalyst...

Using the sol-gel approach, lead-free ME particulate composites (1x)BNT x CZFMO (x=0, 0.1, 0.2, 0.3) are generated without any impurity phase. The coexistence of both phases is confirmed by XRD analysis. In this composite series, αE was found to be highly influenced content. With x=0.2 particle composite, a maximum value 58 mV/cmOe found. presence P-E loops and well-saturated M-H loop in samples indicates that ferroelectric magnetic characteristics well maintained. At 220oC 320oC,...
An important step in creating outdoor insulators is to assess the polymeric housing materials' resistance weathering and electrical tracking. The terms "erosion" "tracking" refer weight loss of material production a surface carbonaceous trail, respectively. With help common tracking erosion tests, composites can only be ranked relative one another their resistance, which makes it impossible quantify these properties absolute terms. Failure due track was major issue during early stages usage...
