Nanostructured metal surfaces comprised of periodically arranged spherical voids are grown by electrochemical deposition through a self-assembled template. Detailed measurements of the angle- and orientation-dependent reflectivity reveal the spectral dispersion, from which we identify the presence of both delocalized Bragg and localized Mie plasmons. These couple strongly producing bonding and ...

It was discovered recently that sparse decomposition by signal dictionaries results in dramatic improvement of the qualities of blind source separation. We exploit sparse decomposition of a source in order to extract it from multidimensional sensor data, in applications where a rough template of the source is known. This leads to a convex optimization problem, which is solved by a Newton-type m...

Interfacing large volume samples (0.5 – 3 mL) with microfluidic devices is a significant obstacle for the processing of numerous forms of forensic casework biological evidence. This includes biological fluids collected from surfaces, clothing and compromised samples e.g., those mixed with soil. In addition, some samples are deliberately diluted, reducing the effect of inhibitors on the polymera...

Dye sensitized solar cell was fabricated from a double layer photoanode. First, TiO2 nanoparticles  were synthesized by hydrothermal method. These TiO2 NPs were deposited on FTO glasses by electrophoretic deposition  method in applied voltage of 5 V and EPD time of 2.5-10 min. Then TiO2 hollow spheres (HSs) were synthesized by sacrificed template method with Carbon Spheres as template and TTIP ...

We describe a method for direct cycle sequencing of PCR fragments amplified from genomic DNA or cDNA. DNA sequencing template is amplified using PCR and oligonucleotide primers flanking the region of interest. The amplified fragment is directly cycle sequenced using fluorescent sequencing primers, Sanger dideoxy sequencing chemistry and an enzyme mixture of a mutant Taq DNA polymerase and therm...

The development of a sequence-general nucleic acid copying system is an essential step in the assembly of a synthetic protocell, an autonomously replicating spatially localized chemical system capable of spontaneous Darwinian evolution. Previously described nonenzymatic template-copying experiments have validated the concept of nonenzymatic replication, but have not yet achieved robust, sequenc...

Electron microscopy (EM) is one of the key experimental techniques in modern structural biology[4]. Three-dimensional structures of large macro-molecular complexes can be solved by EM which otherwise would be impossible using X-ray crystallography or NMR. A common reconstruction technique, from 2D EM images to 3D structure, assigns 2D images to 2D projections of some initial 3D template[5, 1]. ...

The mechanisms that control N-protein-dependent antitermination in the phage lambda life cycle have counterparts in the regulatory systems of other organisms. Here we examine N-dependent antitermination at the intrinsic tR' terminator of lambda to elucidate the regulatory principles involved. The tR' terminator consists of a sequence of six base-pairs along the template at which the transcripti...

a novel modified ni-zsm-5 nanozeolite was fabricated via an organic template-free hydrothermal route. the average particle size of ni-zsm-5 nanozeolite was calculated to be 85 nm by scanning electronic microscopy. then, carbon paste electrode (cpe) was modified by ni-zsm-5 nanozeolite and ni2+ ions were then incorporated to the nanozeolite matrix. electrochemical behavior of this electrode was ...
