“…The n-MASnI 3 and p-MASnI 3 layers were obtained by varying the MASnI 3 doping concentration of the absorber layer to replace the ETL and HTL. The designed device structure is FTO/n-MASnI 3 /i-MASnI 3 /p-MASnI 3 /Au, and considering the defects between the interfaces, 16 we set two interface defect layers (IDL1 and IDL2) between n-MASnI 3 /i-MASnI 3 and i-MASnI 3 /p-MASnI 3 , respectively. The structure diagram and energy band diagram of the device are shown in Figs.…”

“…The parameters of the device structure can be found through the reported literature and experimental results. Using SCAPS-1D we selected reasonable parameters for each layer of the device modeling, [16][17][18] as shown in Table I. The capture cross section of i-MASnI 3 and i-MASnI 3 interfacial defect layer defects 1 × 10 -15 cm 2 with a defect density of 1 × 10 18 cm −3 .…”

Due to their non-toxic nature and good charge transport properties, tin-based perovskite solar cells are gaining attention. Here, we used SCAPS-1D (Solar Cell Capacitance Simulator) to simulate and analyze constructed devices. We then created n-MASnI3 and p-MASnI3 layers that facilitate electron-hole transport by changing the doping concentration of MASnI3 in the perovskite absorber layer, replacing the conventional electron transport layer (ETL) and hole transport layer (HTL). This simplifies the manufacturing process to reduce cost and realize the conversion of lead-free perovskite solar cells. By studying the thickness of n-MASnI3 and p-MASnI3, and the acceptor and donor doping concentrations (ND and NA), we explored the effects on each device performance parameter in terms of energy band distribution, recombination rate variation, and external quantum efficiency. The first optimization of the electron transport layer and hole transport layer was thereby achieved. A second optimized analysis of the doping concentration of i-MASnI3 absorber layer was achieved. Finally, we optimized the device performance parameters as V OC = 0.8827 V, J SC = 23.1720 mA cm−2, FF = 63.1390% and PCE = 12.9144%.

“…19 It has achieved great attention since the privileged framework is frequently observed as a bioactive component in commercially available medicines, for example, Floxan 2 (anti-inflammatory medicine), pyrazomycin 3 (anticancer), difenamizole 4 (anti-inflammatory drug), and deramaxx 5 (NSAID) (Figure 1). 22,23 It is also utilized in paint and photographic industries and in the development of heat resistant resins. 24 The corresponding 3-oxygenated derivative, pyrazolone 6, which has an additional keto-group, is the basic component in drugs such as metamizole sodium and phenylbutazone (both are non-steroidal anti-inflammatory medicines, generally used as powerful painkillers and fever reducers) ( Figure 1).…”

Pyrazole, a five-membered heterocycle containing two nitrogen atoms, is extensively found as a core framework in a huge library of heterocyclic compounds that envelops promising agro-chemical, fluorescent and biological potencies. Attributed to its several potential applications, there is a rise in the significance of designing novel pyrazoles, disclosing innovative routes for synthesizing pyrazoles, examining different potencies of pyrazoles, and seeking for potential applications of pyrazoles. This review consists of two parts. The first part provides an overview on the recent developments in synthetic approaches to pyrazoles, which is related to the new or advanced catalysts and other 'environment-friendly' procedures, including heterogeneous catalytic systems, ligand-free systems, ultrasound and microwave-assisted reactions. The second part focuses on the recently reported novel biological affinities of pyrazoles. This systematic review covers the published studies from 1990 to date. It is expected that this review will be helpful in future research and for new thoughts in the quest for rational designs for developing more promising pyrazoles.

Upon reaction with α,β‐unsaturated nitriles (2 a–d) and/or salicylaldehyde, 3‐(naphthalen‐2‐yl)‐3‐oxopropanenitrile (1) yields pyridine derivatives 3 a–d and/or the imino chromene derivative 4. Compound 1 reacted with phenyl isothiocyanate in a basic medium to give the intermediate potassium salt 6. Upon stirring at room temperature, the intermediate 6 with some α‐halogenated compounds yielded the acyclic compounds 7, 9, 11, 13, and 15. On the other hand, refluxing intermediate 6 with the same α‐halogenated compounds in DMF in the presence of TEA afforded the corresponding thiophene derivatives 8, 10, 12, 14, and 16. The reaction of thiol 17 with hydrazine hydrate derivatives 18 a–d yielded the corresponding pyrazole derivatives 21 a–d. Compound 20 reacted with o‐phenylenediamine or o‐aminothiophenol in the presence of DMF/TEA to give the corresponding benzothiazole or benzoimidazole derivatives 27 a and 27 b, respectively. Thirty new synthesized compounds were examined for their antibacterial activity against Gram‐positive bacteria including S. aureus and B. subtilis, Gram‐negative bacteria such as P. aeruginosa and E. coli, and yeast‐like fungi like C. albicans in vitro. Compounds 15, 16, 21 d, 27 a, 27 b, exhibited the highest antibacterial activity against Gram‐positive bacteria. Molecular docking experiments were conducted to explore the binding affinities and interaction modalities of selected derivatives with the target PDB‐3cmt protein.
