| 1 | A review on perovskite solar cells (PSCs),materials and applications显示文摘In recent years,the perovskite solar cells have gained much attention because of their ever-increasing power conversion efficiency(PCE),simple solution fabrication process,flyable,light-weight wearable and deployable for ultra-lightweight space and low-cost materials constituents etc.Over the last few years,the efficiency of perovskite solar cells has surpassed 25%due to high-quality perovskite-film accomplished through low-temperature synthesis techniques along with developing suitable interface and electrode-materials.Besides,the stability of perovskite solar cells has attracted much well-deserved attention.In this article we have focused on recent progress of the perovskite solar cells regarding their crystallinity,morphology and synthesis techniques.Also,demonstrated different layers such as electron transport-layers(ETLs),hole transport-layers(HTLs)and buffer-layers utilized in perovskite solar-cells,considering their band gap,carrier mobility,transmittance etc.Outlook of various tin(Sn),carbon and polymer-based perovskite solar cells and their potential of commercialization feasibility has also been discussed. | N.Suresh Kumar K.Chandra Babu Naidu | 2021 | Journal of Materiomics2021，7，5： | 1 |
| 3 | Development and validation of a stability-indicating RP–HPLC method for estimation of atazanavir sulfate in bulk显示文摘A stability-indicating reverse phase–high performance liquid chromatography(RP–HPLC) method was developed and validated for the determination of atazanavir sulfate in tablet dosage forms using C_(18) column Phenomenix(250 mm×4.6 mm, 5 μm) with a mobile phase consisting of 900 mL of HPLC grade methanol and100 mL of water of HPLC grade. The pH was adjusted to 3.55 with acetic acid. The mobile phase was sonicated for 10 min and filtered through a 0.45 μm membrane filter at a flow rate of 0.5 mL/min. The detection was carried out at 249 nm and retention time of atazanavir sulfate was found to be 8.323 min. Linearity was observed from 10 to 90 μg/mL(coefficient of determination R^2 was 0.999) with equation, y=23.427x+37.732.Atazanavir sulfate was subjected to stress conditions including acidic, alkaline, oxidation, photolysis and thermal degradation, and the results showed that it was more sensitive towards acidic degradation. The method was validated as per ICH guidelines. | S.Dey S.Subhasis Patro N.Suresh Babu P.N.Murthy S.K.Panda | 2017 | Journal of Pharmaceutical Analysis2017，7，2： | 0 |
