Among the benefits they provide, such as being easily reproducible and affordable, they pose their own problems with device degradation, stability, and surface wettability. We probed the graphene oxide doped PEDOT:PSS (GO)/poly(3,4 ethylenedioxythiophene):poly(styrene sulfonate) composite for the application in 2D carbonaceous hole transport layers to improve perovskite solar cells. Advantages and problems are pointed out as well as new perspectives to further modify and retract the drawbacks of conducting polymers. We discussed the advancement of the hole transport layer and described the effects of graphene oxide (dopant) on device transmission, surface wettability, and film quality. Basic principles and mechanisms are covered in the development of polymeric hole transport layers and interfacial properties. Findings included the decrease in device transmission, lessened oxidation of the perovskite, and superior surface wettability. This work highlights the importance and relevance of thin, flexible and powerful photovoltaic systems.","PeriodicalId":14902,"journal":{"name":"Journal of Advanced Chemical Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91454855","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The marine macroscopic brown seaweed Colpomenia sinuosa was used in the experimental study for the biosynthesis of silver nanoparticle since they are rich in phytochemicals, bioactive compounds and secondary metabolites which has reducing agents that may be environmentally acceptable and eco-friendly. The biosynthesized silver nanoparticles from marine macroscopic brown seaweed were characterized by UV-vis spectroscopy which confirmed the surface plasmon resonance of silver nanoparticles, Fourier transform infrared (FT-IR) spectroscopy to identify the presence of various functional groups in biomolecules responsible for the bio reduction of Ag+ and capping/stabilization of silver nanoparticles. X-ray diffraction (XRD) to observe face center cubic (fcc) and crystalline nature of silver nanoparticles, thermogravimetric analysis (TGA) which revealed the thermal stability and purity of the silver nanoparticles.

The CWs were characterized using FTIR, XRD and the results conform the structure of cellulose. XRD studies showed that the percentage crystallinity of bleached fibres is about 93%. The particle size analysis showed a bimodal distribution for CWs where approximately 21% of the sample has average size of 110 nm. The rubber compounds were prepared according to a general tyre tread formulation while incorporating the purified CWs in diluted centrifuged latex (NR) followed by converting them into rubber sheets to produce cellulose whiskers/natural rubber CW/NR composite. Meanwhile, the control was prepared without incorporating CW in the diluted centrifuged latex. The lowest Mooney viscosity and the highest stress relaxation coefficient of CW/NR composites ensured higher processability. Curing characteristics of the compounds were evaluated at 120 °C and physical properties were evaluated on par to the ASTM standards. The highest cure rate and better scorch time were observed in CW/NR composite. Most of the physical properties were superior. In overall, it is obvious that cellulose whiskers have a potential to use as reinforcing material for natural rubber tyre tread compounds.","PeriodicalId":14902,"journal":{"name":"Journal of Advanced Chemical Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76921385","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The plant is used in traditional pharmacopoeia to treat dysentery, bronchial infections, infections from stings, gallbladder caused by fever and intestinal problems. Chemical study of the CH2Cl2-MeOH (1:1) extract led to the isolation of six compounds: (22E, 24S)-stigmasta-5,22,25-trien-3β-ol (1); 3,4,5,7-tetrahydroxyflavone (luteolin) (2); quercetin (3); kaempferol-7-O-β-D-glucoside (4); alphitolic acid (5); β-sitosteryl palmitate (6). The compounds (22E, 24S)-stigmasta-5,22,25-trien-3β-ol (1); 3,4,5,7-tetrahydroxyflavone (luteolin) (2); kaempferol-7-O-β-D-glucoside (4); alphitolic acid (5) and β-sitosteryl palmitate (6) were isolated from Albizia ferruginea for the first time. The structures of the isolated compounds were determined based on spectroscopic analysis and comparison of their spectral data with those in literature. The results of the antioxidant test revealed that at a dosage of 75 μg/mL the percentage weight of compound 3 was the highest, at dosages of 100 and 300 μg/mL, compound 2 was highest and at dosage of 150 μg/mL, compound 1 was the highest.
