Microstructured Ni/PPy (PPy: polypyrrole) core/shell composites were prepared from an in situ chemical oxidative polymerization of pyrrole (Py) monomer the presence Ni powder, with ammonium persulfate (APS) as oxidant and citric acid (C6H8O7) dopant. X-ray diffraction Fourier transform infrared analyses indicate that there is no interaction between powder protonated PPy. The mass percentages PPy, calculated remanent weight after thermogravimetric analysis, are consistent those designed. soft...
Metal/semiconductor hybrid materials of various sizes and morphologies have many applications in areas such as catalysis sensing. Various organic agents are necessary to stabilize metal nanoparticles during synthesis, which leads a layer compounds present at the interfaces between particles semiconductor supports. Generally, high-temperature oxidative treatment is used remove organics, can extensively change size morphology particles, turn altering their activity. Here we report facile...

Among plant metabolites, phenolamides, which are conjugates of hydroxycinnamic acid derivatives and polyamines, play important roles in adaptation to abiotic biotic stresses. However, the molecular mechanisms underlying phenolamide metabolism regulation as well effects domestication breeding on diversity tomato remain largely unclear. In this study, we performed a metabolite-based genome-wide association study identified two biosynthetic gene clusters (BGC7 BGC11) containing 12 genes...
Nickel nanomaterials with a wide range of morphologies and sizes, such as superfine nanoparticles, urchinlike chains, smooth rings, hexagonal Ni/Ni(OH)2 heterogeneous structure plates, are synthesized in single reaction system by simply adjusting the conditions. The morphology transformation mechanism is systematically investigated. Magnetic measurement rings shows that saturation magnetization (Ms) decreases reduced sample size, remanent (Mr) increasing temperature. Additionally, coercivity...
Significance The search for high-efficiency thermoelectric materials encompasses many classes of semiconductors. Zintl phases are attractive applications. Here, we report the high performance rarely studied bismuth (Bi)-based (Eu 0.5 Yb ) 1−x Ca x Mg 2 Bi with record figure-of-merit ZT as 1.3 at 873 K. This value is, to our knowledge, highest ever reported in CaAl Si -based structures, especially compared best antimony (Sb)-based YbZn 0.4 Cd 1.6 Sb compound. Because Sb-based compounds have...
