Analysis of complete chloroplast genome sequence of Korean landrace .

The complete chloroplast genome sequence of Korean acc smg222 was analyzed. Based on a comparison with Chinese , losses of nine subunits (A, B, C, D, E, F, H, J, and K), three protein-coding genes ( 1-like, 15, and 68), six transfer RNAs, and one conserved open reading frame ( 42). In addition, 219 InDels (insertion or deletion) and 171 simple sequence repeats were observed.

Chemically Driven, Water-Soluble Composites of Carbon Nanotubes and Silver Nanoparticles as Stretchable Conductors.

In the past decade, hybrid materials for highly stretchable, conductive electrodes have received tremendous attention in the fields of emerging wearable electronic, optoelectronic, and sensing devices. Here, we present a previously unrecognized aqueous route to producing stretchable conductors composed of silver nanoparticles (AgNPs) and single-walled carbon nanotubes (SWNTs) embedded in a polyurethane (PU) matrix, in contrast to ones dispersed in toxic organic solvents reported to date. The intact chemical interaction between one-dimensional SWNTs, for endowing the capability of establishing conductive pathways even in stretching conditions, and AgNPs, for enabling high conductivity of the composites, is achieved in an aqueous medium with an anionic polyelectrolyte, poly(acrylic acid), that undergoes pH-dependent conformational evolution.
