Gold-iron oxide nano-heterostructures with a clear and well-defined morphology were prepared via a seed-assisted method. The synthesis process and the events of heterogeneous nucleation during the decomposition of the iron precursor were carefully studied in order to understand the mechanism of the reaction and to tailor the architecture of the fabricated heterostructures. When employing Au seeds of 3 and 5 nm, nanoparticles with a dimer-like morphology were produced due to the occurrence of a single iron oxide nucleation event. Otherwise, multi-nucleation events could be favored by two mechanisms:(i) by the incorporation of a reducing agent and the slowing down of the heating protocol, leading to a core-shell system;(ii) by the increase of the Au seed size to 8 nm, leading to a flower-like system. Further increase of the Au seed size to 12 nm using similar synthesis conditions promotes the homogeneous nucleation and growth of the iron oxide phase, without formation of heterostructures. An in-depth study was performed on the gold-iron oxide heterostructures to confirm the epitaxial growth of the oxide domain over the Au seed and to analyze the elemental distribution of the components within the heterostructures. Finally, it was found that the modification of the plasmonic properties of the Au nanoparticles are strongly influenced by the architecture of the heterostructure, with a more pronounced damping effect for the systems produced after multi-nucleation events.

Dear Editor,Metabolically induced cancer heterogeneity creates a large source of novel potential targets towards an enhanced therapeutic window alone and in combination with classic chemo-and radiotherapy[1,2].This is of particular interest for non-small cell lung cancer(NSCLC),which accounts for more than 80%of all lung tumor types characterized by limited responses to current treatment options[3–5].

在马里兰阿奎亚含水层中HCO_3^-的稳定碳同位素:CO_2同位素重源的论证

HCO_3^-的浓度和溶解无机碳的δ^(13)C值是沿着阿奎亚含水层的水力坡降而变化的。在地层出露区,有土壤气体CO_2(δ^(13)C≈-26/ml)存在时,雨水补给使碳酸质介壳溶解得更快.(δ^(13)C≈0.0/ml)在这些地区内,HCO_3^-浓度一般为150～200m g/J,溶解HCO_3^-的δ^(13)C值接近-13/ml。随着水流远离露头区,HCO_3^-的浓度逐渐降低(约130mg/l),而δ^(13)C值则稍有增加(约-11.4/ml)。这种趋势影响亚稳态碳酸质介壳物质的进一步溶解和次生方解石胶结物的再次沉淀.水流系统中,下降坡度约40哩时.HCO_3^-浓度急剧增加(约为400mg/l),δ^(13)C值大大加重(约为δ^(13)C≈-6.2/ml),在这一坡降水流内,所观测到的Na^+与HCO_3^-的克分子比表明:同位素重碳酸介壳物质的溶解本身不能说明所观测到的δ^(13)C的趋势,更确切地说,Na^+:HCO_3^-的比率表明介壳物质的溶解作用必须在CO_2的参与下进行.由于这一地区内的合水层既与土壤气体也与大气的CO_2隔离.所以同位素的重CO_2(δ^(13)C≈-5.3/ml)明显地来源于含水层自身.含水层中CO_2的生成可能来自褐煤含水层物质的细菌媒介发酵和细菌煤介甲烷的成因。
