  • A new peanut cultivar "Jopyeong" (Arachis hypogaea ssp. hypogaea L.) was developed at the Yeongnam Agricultural Research Institute, NICS, in Milyang in 2006. It was developed from the cross between the very short stem cultivar "CUP brittle" and the high-yielding cultivar "Daekwang". "Jopyeong" which is Virginia plant type has 23 branch number per plant with early maturing and ellipse-shaped large kernel. Each pod has two grains with brown testa and 100 seed weight was 87g in the regional yield trials (RYT). This variety also showed more resistant to late leaf spots compared with check one. Especially it has resistance to lodging owing to short stem and erect plant type. In the regional yield trials "Jopyeong" was out-yielded than check variety by 11% with 8.37 ton/ha for fresh pod and by 4% with 3.95 ton/ha for grain.

  • A new peanut variety "Charmpyeong" (Arachis hypogaea ssp. hypogaea L.) was developed at the Yeongnam Agricultural Research Institute, NICS, in Milyang in 2007. It was developed from the cross between the high-yielding cultivar "Shindaekwang" and the very short stem cultivar "ICGV94216". This Virginia plant typed "Charmpyeong" has 33 cm stem height and 18 branch number Each pod with ellipse-shaped large kernel has two grains with brown testa and 100 seed weight was 88 g in the regional yield trials (RYT). This variety also showed more resistant to web blotch compared with check one. Especially it has resistance to lodging until harvesting owing to short stem. In the regional yield trials "Charmpyeong" was outyielded than check variety by 13% with 4.35 MT/ha for grain.

  • A new peanut variety 'Daan'(Arachis hypogaea ssp. hypogaea L.) was developed at the Department of Southern Area Crop Science, National Institute of Crop Science (NICS) in Milyang 2014. This was developed from the cross between 'Iksan 31' with Virginia typed short stem and 'Dakwang' with Shinpung-typed larger grain. 'Daan' which is a Shinpung plant type had 13 branches per plant and its length of main stem was 44cm. Each pod has two grains with brown testa and long ellipse-shaped large kernel. Its yield components showed 34 pods per plant, 127 g of 100-seed-weight and 75% of pod shelling ratio in the regional yield trials (RYT). Seed quality showed 47.8% of crude oil and 28.3% of protein content. This variety showed resistant to early leaf spot and had more resistant to late leaf spot, stem rot and lodging, compared to reference variety. In the regional yield trials for 3 years 'Daan' was more productive than reference variety by 16% with 5.00 MT/ha for grain production.

  • We report the laser-induced formation of peanut-shaped gold nanoparticles (Au nanopeanuts) and gold nanowires (AuNWs), and their morphological properties. Pulsed laser irradiation of citrate-capped gold nanoparticles at 532 nm induces fragmentation, spherical growth, the formation of Au nanopeanuts, and the formation of AuNWs, sequentially. High-resolution transmission electron microscopy images reveal that the Au nanopeanuts are formed by instantaneous fusion of spherical nanoparticles in random orientation by laser heating. Furthermore, Au nanopeanuts are bridged in a linear direction to form AuNWs by an amorphous accumulation of gold atoms in the junction. The laser-produced Au nanopeanuts and AuNWs slowly disintegrate, restoring the spherical shape of the original Au nanoparticles when the laser irradiation is stopped. The addition of citrate effectively prevents them from transforming back to the nanospheres.

  • With synthesis temperature and adding amount of oleylamine, nanometer-sized Cu particles were fabricated by heptyl alcohol-based chemical synthesis. The synthetic temperature and amount of oleylamine changed excessively the shape and phase of synthesized nanoparticles. Only cubic-shaped $Cu_2O$ phase was formed at $160^{\circ}C$ regardless of the amount of oleylamine because of imperfect reduction reaction, representing results that the average size of $Cu_2O$ particles decreased with increasing the amount of oleylamine. In the case the synthesis at $170^{\circ}C$, however, nanoparticles of irregular sphere or peanut shapes were synthesized. Moreover, the average size of nanoparticles decreased continuously and gradually with an increase of the amount of oleylamine. According to the size decrease, the synthesized $Cu_2O$ nanoparticles were also transformed into pure Cu nanoparticles.
