BACKGROUND Scleroderma is a clinically heterogeneous disease with a complex phenotype. The disease is characterized by vascular dysfunction, tissue fibrosis, internal organ dysfunction, and immune dysfunction resulting in autoantibody production. METHODOLOGY AND FINDINGS We analyzed the genome-wide patterns of gene expression with DNA microarrays in skin biopsies from distinct scleroderma sub...

Radiant energy (solar energy) plays a vital role due to its continuous power supply and environmentally friendly in meeting the people’s demand. The need for an endless of energy, majorly through solar exploitation has driven expansion diversification device proper storage. This review summarizes photo-supercapacitor’s working mechanism. classification supercapacitor was discussed advancements ...

Dye sensitized solar cells (DSSC) are a promising technological alternative to conventional pn-junction solar cells, and therefore attract considerable scientific interest. Different attempts have been made to replace the liquid electrolyte by a solid state hole conducting organic or inorganic medium. This contribution compares electrical properties of three different types of DSSCs. First, we ...

Surface modification plays a crucial role in improving the efficiency of dye-sensitized solar cells (DSSCs), but the reported surface treatments are in general superior to the untreated TiO(2) but inferior to the typical TiCl(4)-treated TiO(2) in terms of solar cell performance. This work demonstrates a two-step treatment of the nanoporous titania surface with strontium acetate [Sr(OAc)(2)] and...

Porous zinc oxide (ZnO) nanosheet (NS) arrays constructed by connected nanocrystallites were built on weaved metal wire (WMW) via hydrothermal treatment followed by calcination, and used as photoanodes for flexible dye-sensitized solar cells (DSSCs). An overall light-to-electricity conversion efficiency (η) of 2.70% was achieved for the DSSC under 100 mW cm(-2) illumination, and this η was foun...

Dye-sensitized solar cell (DSSC) is one of the promising photovoltaic (PV) technologies for applications requiring high aesthetic features combined with energy production such as building integration PV (BIPV). In this context, DSSCs have ability to be wavelength selective, thanks development new sensitizers by molecular engineering. The long history dye research has afforded technology differe...

Teknik preparasi dengan tmetode slip casting. Setelah dilakukan pengujian dan perhitungan diperoleh hasil bahwa Fear factor (FF) penggunaan counter elektode DSSC masih relatif kecil sebesar 270.10-6, efisiensi (ƞ) 540.10-6.

[111]- and {010}-faceted anatase nanocrystals with controllable crystal size and morphology were synthesized from tri-titanate H2Ti3O7 nanosheets by hydrothermal reaction. The nanostructures and the formation reaction mechanism of the obtained TiO2 nanocrystals were investigated using XRD, FE-SEM, and TEM. Furthermore, the photocatalytic and dye-sensitized solar cell (DSSC) performances of the ...

Using a simple hydrothermal synthesis, the crystal structure of TiO2 nanoparticles was controlled from rutile to anatase using a sugar alcohol, D-sorbitol. Adding small amounts of D-sorbitol to an aqueous TiCl4 solution resulted in changes in the crystal phase, particle size, and surface area by affecting the hydrolysis rate of TiCl4. These changes led to improvements of the solar-to-electrical...
