The sensitivity and limits of detection (LOD) chemiresistive gas sensors can often be improved by increasing the surface area sensing material that interacts with analyte. This process is referred to as nanostructuring. Nanostructured polypyrrole (PPy) for ammonia were created aid a nanosphere template. Polystyrene nanospheres are deposited form template between interdigitated electrodes, chron...

mfi zeolite membranes were prepared on porous α-alumina substrates, using secondary growth of nano-seeded layers. the resulting membranes were characterized by means of scanning electron microscopy (sem), x-ray diffractometry (xrd), and pervaporation performance tests for separation of benzene, toluene and xylene (btx) mixture from contaminated water. the morphology, thickness, homogeneity, cry...

metal complexes, ml (m=ni, cu, co and zn) of unsymmetrical tetradentate schiff base have been synthesized by the template reaction of the half-units n-(1-hydroxy-2-acetonaphthone)-1-amino-2-phenyleneimine)(hl1) with 2-pyrroleca-rbaldehyde. the complexes have been characterized by elemental analysis, ir, 1h nmr and uv spectroscopy. the crystal structure of the ni(ii) complex has been determine...

Apoferritin single crystals are used as a template to prepare oriented and ordered mesoporous silica structures. Condensation of pre-hydrolyzed precursors takes place within the crystal voids, transferring hierarchical structure silica. A porous framework is created after protein removal by calcination, which provides high control over spatial orientation size individual pores.

Abstract Bioinspired from structural coloration of butterfly wing structure, this work aims to fabricate nanoporous chitosan for UVC reflection. By taking advantage self-assembled polystyrene- b -polydimethylsiloxane (PS- -PDMS) with double gyroid texture followed by hydrofluoric acid etching PDMS block, PS well-defined nanochannels can be fabricated, and used as a template templated crosslinki...

Hollow/porous nanoparticles, including nanocarriers, nanoshells, and mesoporous materials have applications in catalysis, photonics, biosensing, and delivery of theranostic agents. Using a hierarchical template synthesis scheme, we have synthesized a nanocarrier mimicking a golf ball, consisting of (i) solid silica core with a pitted gold surface and (ii) a hollow/porous gold shell without sili...

Telomerase is a ribonucleoprotein that catalyzes telomere elongation in vitro and in vivo. The 159-nucleotide RNA component of Tetrahymena telomerase contains the sequence 5'-CAACCCCAA-3' ("template region"), which serves as a template for the addition of the sequence d(TTGGGG)n to Tetrahymena telomeres. To dissect the Tetrahymena telomerase enzyme mechanism, we developed a functional in vitro ...
