Tuning charge transport properties using silver-cobalt bimetallic nanoparticles is investigated to enhance the photo-current collection in polymer solar cells. The were not only augmenting processes but also expected trap light by way of reflection. polymers blend consisting poly-(3-hexylthiophene) (P3HT):[6,6]-phenyl C61 butyric acid methyl ester (PC61BM) used fabrication experimental results ...

The conserved U54 in tRNA is often modified to 5-methyluridine (m(5)U) and forms a reverse Hoogsteen base pair with A58 that stabilizes the L-shaped tRNA structure. In Gram-positive and some Gram-negative eubacteria, m(5)U54 is produced by folate/FAD-dependent tRNA (m(5)U54) methyltransferase (TrmFO). TrmFO utilizes N(5),N(10)-methylenetetrahydrofolate (CH(2)THF) as a methyl donor. We previousl...

The hepatitis B virus X protein (HBx) sequence (154 aa) has been divided into six regions (A-F) based on its sequence homology with X proteins of other mammalian hepadnaviruses. Regions A, C, and E are more conserved and include all the four conserved cysteines (C7, C61, C69, and C137). To localize the regions of HBx important for transactivation, a panel of 10 deletion mutants (X5-X14) and 4 s...

The fullerene-based derivative phenyl-C61-butyric acid methyl ester (PCBM) has attracted attention as an n-type transistor channel and organic photovoltaic material due to its solution processability, stability, high electron mobility. However, disorder in solution-processed PCBM thin films makes understanding of charge carrier transport mechanisms difficult. We have fabricated PCBM-based field...

Engineering the energetics of perovskite solar cells through introduction surface dipoles that assist with charge carrier extraction is a promising route to enhance device performance without altering other layers or fabrication parameters. In this work, we introduce four different derivatives dicationic phosphonium-bridged ladder stilbenes (PYMC) in inverted structure ITO/Meo-2pacz/perovskite/...

Arsenic (III) methyltransferase (AS3MT) catalyzes the process of arsenic methylation. Each arsenite (iAs(3+)) binds to three cysteine residues, methylarsenite (MMA(3+)) binds to two, and dimethylarsenite (DMA(3+)) binds to one. However, only two As-binding sites (Cys156 and Cys206) have been confirmed on human AS3MT (hAS3MT). The third As-binding site is still undefined. Residue Cys72 in Cyanid...
