PENGARUH DOPING Al PADA LAPISAN ZnO TERHADAP EFISIENSI DYE SENSITIZED SOLAR CELLS (DSSC)

Telah dilakukan pendopingan aluminium pada lapisan ZnO yang bertujuan untuk meningkatkan nilai efisiensi Dye Sensitized Solar Cells (DSSC) dan mengkaji konsentrasi doping terbaik dalam peningkatan nilai efisiensi. Sintesis lapisan ZnO tersebut menggunakan metode Liquid Phase Deposition (LPD) pada suhu 80 oC selama 10 jam dengan variasi doping aluminium sebesar 0%; 1,0%; 1,5%; 2,0%; dan 2,5%. Karakterisasi sampel dilakukan dengan XRD dan Spektroskopi UV-Vis sedangkan efisiensi DSSC diukur dengan menganalisis karakteristik I-V. Pola difraksi XRD lapisan ZnO tanpa doping dan terdoping Al 1,5% memperlihatkan pola difraksi yang identik, yaitu terdapat puncak pada 2θ: 34 dan 36 yang menunjukkan karakteristik difraksi ZnO. Spektrum UV-Vis memperlihatkan absorpsi kuat terjadi pada rentang panjang gelombang 280-380 nm dan energi gap yang didapatkan adalah 3,51; 3,50; 3,3; 3,11 dan 3,06 eV untuk 0%; 1,0%; 1,5%; 2,0% dan 2,5%, berturut-turut. Efisiensi DSSC sampel diukur menggunakan multimeter digital dan perangkat tambahan dengan intensitas cahaya 500-1500 Lux. Efisiensi tertinggi dihasilkan elektroda kerja lapisan ZnO yang didoping aluminium 1,5%, yaitu sebesar 1,51% sedangkan efisiensi terendah yaitu elektroda kerja tanpa doping sebesar 0.33%. sehingga pemberian doping 1.5% mampu meningkatkan efisiensi sebesar 463% dibandingkan DSSC tanpa doping.

Satellite Image Processing for Biodiversity Conservation and Environmental Modeling in Kyrgyz Republic National Park

There is a need for extensive surveys of living organisms at a global scale; digital data exchange and storage is an essential part of such studies. Biodiversity inventory of fungi, which play an essential role in the health of the mountainous conifer forests of a developing country – Kyrgyz Republic, was linked to the vegetation classification produced from the high-resolution satellite imagery. Terra ASTER and SRTM90 imagery was used as a base map for the ecosystem modeling of the species and habitat distribution and for the three-dimensional representation, especially valuable for the mountainous landscapes of the Ala Archa National Park. Image processing techniques with ER Mapper and ArcGIS/ArcInfo using ASTER bands and band ratios (NDVI, Brovey transform and 3/1, 4/3, 10/1) allowed distinguishing between vegetation community types and their complexes: mixed conifer and deciduous forests, dwarf juniper forests, cushion plants, shrublands, alpine grasslands, steppes, sagebrush semi-deserts, and complexes of grasslands and conifers

Taxonomic position of the genus \u3cem\u3eSimonoides\u3c/em\u3e Vachon et Farzanpay, 1987, and description of a new species of \u3cem\u3eOrthochirus\u3c/em\u3e Karsch from Iran (Scorpiones, Buthidae)

Simonoides Vachon et Farzanpay, 1987 is synonymized with Orthochirus Karsch, 1891. Lectotype is designated for Simonoides farzanpayi Vachon et Farzanpay, 1987. Orthochirus sobotniki Kovařík, 2004 is synonymized with Orthochirus farzanpayi (Vachon et Farzanpay, 1987), comb. n. Orthochirus gruberi, sp. n. (Iran) is described and dis-tinguished from all other Iranian species of the genus on a combination of two characters, the presence of rows of granules with internal and external granules on the movable fingers of pedipalps and hirsuteness of the entire me-tasoma and telson

A környezetbarát beszerzés gyakorlata Norvégiában és Magyarországon

A Fenntartható fejlődés irányába való törekvések mind vállalati, mind kormányzati szinten jól hasznosíthatják a „zöld beszerzés” gyakorlatát, melynek célja a környezeti és társadalmi szempontok érvényre juttatása a vállalati, illetve kormányzati beszerzési folyamatok során

Evolution of Scorpion Orthobothriotaxy: A Cladistic Approach

This study presents a cladistic analysis of the derivation of orthobothriotaxic patterns in scorpions. Included in this analysis are the original three orthobothriotaxic patterns defined by Vachon (1972, 1974), the pattern of the unique scorpion Pseudochactas ovchinnikovi Gromov, 1998, and two trichobothrial patterns of fossil scorpions, the Upper Carboniferous palaeopisthacanthids and the Lower Cretaceous archaeobuthids. An overview of all fossil scorpion material where trichobothria are reported is presented in detail. The approach used in this analysis is to model the existence of an individual trichobothrium, adopting the ‘absence of’, ‘petite size’ and ‘full size’ as incremental stages of a trichobothrium’s development. Of particular interest is the phylogenetic placement of Pseudochactas within Recent scorpions, for which the results of this study provide preliminary insight. Phylogenetic results of this analysis, based entirely on the derivation of orthobothriotaxic patterns, show that Archaeobuthus is the plesiomorphic sister group of all Recent scorpions, placed between the ancient palaeopisthacanthids and Recent scorpions. Within Recent scorpions, the clades ‘buthids + pseudochactids’ and ‘chaerilids + Type C’ are strongly endorsed by this analysis. Formal orthobothriotaxic types are defined for the palaeopisthacanthids (Type P), representing the earliest known complete fundamental trichobothrial pattern, and the pseudochactids (Type D), the fourth fundamental pattern for Recent scorpions

A new scorpion genus (Scorpiones: Vaejovidae) from Mexico

A new vaejovid genus from Mexico, Franckeus, gen. nov., is described based on unique neobothriotaxy. Species placed in this genus are from the Vaejovis “nigrescens” group (previously called the “nitidulus” group). Six species comprise this new genus, distributed throughout Mexico (mainland as well as Baja California Sur): Franckeus nitidulus, F. rubrimanus, F. platnicki, F. minckleyi, F. kochi and F. peninsularis. A new species of the Vaejovis “nigrescens” group, Vaejovis davidi, sp. nov., is also described
