“…34 Apart from these reports on a BFO-based gas sensor, there are many reports on catalytic doped/substituted and surface-modified BFO, which might enhance its catalytic properties and in turn sensitivity and selectivity. 39,40,59,61,65,66 Bodade et al fabricated an LPG gas sensor by partial substitution of Fe ions by Mn ions on the B site in BFO. Additionally, they observed that loading of 0.8 wt.% Pd on BiFe 0.6 Mn 0.4 O 3 improves sensitivity, response time and selectivity with reduction of operating temperature.…”

“…Resulting large accumulation of electrons from material to adsorbing species creates higher resistance, due to which sensitivity of detection increases more (87% and 78%) for NO 2 and H 2 gases, respectively. 65 Pd or Ag doping in BFO is reported to create a Schottky junction between their interfaces, which causes interfacial effect. 39,59 Fast transfer of electrons from BFO to the dopant species causes shortening of the electron life in BFO which results in high sensitivity toward target gas species, namely chlorine and LPG.…”

Development of highly sensitive, stable and reliable eco-friendly gas sensors is still an open-ended research domain and thus demands many related materials. Bismuth-based compounds form an important material platform in such developments; however, they are so far not reviewed. This review highlights the detailed gas sensing attributes for a range of gases and humidity for n-type and p-type as well as mixed composite materials and influences of catalytic doping on gas sensing in different bismuth-based composites. The future scope in the development of such gas sensors leading to commercialization is also discussed.

“…Multiferroics are among the special class of materials having ferroelectric and ferromagnetic phases simultaneously and being studied extensively in the recent past as they offer some of the most promising applications of technological importance [1][2][3][4][5]. Among various multiferroic materials, BiFeO 3 (BFO) has emerged as a potential material offering a wide range of viable applications in next-generation actuators, sensors, non-volatile memory devices (FeRAMs), and photovoltaics as it has many intriguing properties such as robust ferroelectricity, magnetism, and photovoltaic effects [6][7][8][9][10]. Furthermore, BFO allows the tuning of magnetic properties by applying an electric field, i.e., EM coupling (converse ME coupling), and leads to controlled permeability with minimum power consumption.…”

Magnetic and Dielectric Properties of La and Ni Co-substituted BiFeO3 Nanoceramics

The increasing plead for the realization of ultra-fast, miniaturized, compact, and ultra-low power consumption in electronic as well as spintronic devices has propelled the quest for novel multiferroic materials that efficiently enable voltage control of magnetism. The present work reports the phase stability, magnetic and dielectric responses of polycrystalline Bi 1−x La x Fe 1−y Ni y O 3 (0 ≤ x ≥ 0.2 and 0 ≤ y ≥ 0.2) multiferroic ceramics synthesized through a simplistic sol-gel approach. The maneuver substitutions of La at A − site of BiFeO 3 multiferroic eliminate the secondary phases formed owing to impurities. Rietveld refined XRD analysis reveals the structural transformation of the orthorhombic (Pbnm) phase as La substitution increases. However, an additional lattice distortion is induced as a result of the substitutions of Ni atoms at B − site. A substantial enhancement in magnetic and dielectric responses has been found in the co-doped (Ni and La) sample at both A and B − sites as a result of the size confinement of nano-crystallites, the exchange interaction between Fe 3+ and Ni 2+ ions, and corresponding variation in Fe-O-Fe bond angles. The dielectric constant has increased substantially in the low-frequency region with simultaneous substitutions of La and Ni at the sites of Bi and Fe, respectively. A careful observation of temperature-dependent magnetization curves (FC and ZFC) indicates a spin glass response with entangled ferromagnetic components. The experimental findings infer that the co-substitutions of La and Ni at their respective sites in Bi 1−x La x Fe 1−y Ni y O 3 (0 ≤ x ≥ 0.2 and 0 ≤ y ≥ 0.2) may significantly improve the ferromagnetic and dielectric responses of the studied nanoceramics.

“…Tungsten is an important element in chemistry and compounds containing tungsten have wide range of applications not only in chemical laboratories but also in various fields of industries such as catalysts (Kocięcka et al., 2018), optical fibers (Liu et al., 2018b), and sensors (Waghmare et al., 2018), and electrochromic applications (Li et al., 2018a). Meanwhile, tungstate supported catalysts for the synthesis of organic compounds have also been recently applied successfully (Farahi et al., 2017; Karami et al., 2013a, 2013b).…”

A B S T R A C TA novel, nano-sized, bis(3-(piperazine-1-yl)propyl)tungstate (BPPT) is introduced as an efficient and reusable organometallic catalyst which is considered as a heterogeneous Bronsted-Lowry base and applied successfully for one-pot synthesis of methyl 2-amino-4-aryl substituted-4H-chromene derivatives with good to excellent yields. BPPT has been prepared via a two-step route from natrium tungstate salt. At first, the oxygens of Na 2 WO 4 react with 1-bromo-3-chloropropane via nucleophilic substitution to produce bis(3-choloro propyl)tungstate. Then nucleophilic substitution of piperazine with chlorines produced bis(3-(piperazine-1-yl)propyl) tungstate. Bis(3-(piperazine-1-yl)propyl) tungstate, which was called BPPT, characterized by fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), thermal gravimetric analysis (TGA), transmission electron microscopy (TEM) and scanning electron microscope (SEM). The catalyst is heterogeneous, green and recyclable. It is a thermally stable and its handling is easy. Its catalytic activity is very high and leads to the production of 4H-pyran derivatives with good to excellent yields in short reaction times. Furthermore, molecular modeling studies and ADMETox prediction revealed that not only it can inhibit acetylcholinesterase enzyme and act as an anti-Alzheimer agent but also has no variation from Lipinski's rule of five and can be a good candidate as anti-Alzheimer agents. These above-mentioned facts can be countered as advantages of the current protocol.
