„Wenn ich kein Naturwissenschaftler wäre, wäre ich Historiker und würde viele Geheimnisse der japanischen Geschichte aufklären. Ich begutachte wissenschaftliche Arbeiten gerne, weil ich dann auch mehr Arbeiten einreichen kann, ohne mich schuldig zu fühlen …︁“ Dies und mehr von und über Shunichi Fukuzumi finden Sie auf…
Abstract Spectral induced polarization (SIP) measurements are primarily applied for near-surface investigations, where seasonal and meteorological temperature variations are present. Furthermore, investigations at greater depths are influenced by increasing temperatures. Therefore, understanding the temperature-depend…

For multi-photon processed with the linear dispersion in the high-intensity terahertz (THz) field, we have systematically investigated the temperature-dependent nonlinear optical response of graphene-based systems, including single layer graphene, graphene superlattice and gapped graphene. In the intrinsic single laye…
Cu 2-x S nanocrystals (NCs), characterized by low cost, low toxicity, high stability and high photothermal conversion efficiency, provide promising platforms as photothermal agents. Herein, a novel two-step synthesis has been developed for Cu 7 S 4 nanocrystals with hollow structure using the as-prepared copper nanopa…

The chaperonin GroEL is a double-ring structure which is constructed with 7 subunit ring of 57 kD, and those ring forms back to back. GroEL is bound with ATP and the co chaperon GroES for assisting protein folding in the cell. GroES is a septemer ring structure of 10 kD, and forms an asymmetric bullet shaped complex a…
During the last few decades, condensed matter physics has witnessed a deep refoundation of its paradigms, through the discovery of many systems that the usual symmety classification à la Landau cannot handle properly. Although the first major breaktroughs were realized at the time of discovery of integer and fractiona…
A qualidade do solo esta relacionada com sua capacidade de exercer suas funcoes nos diferentes ecossistemas, como sustentar a atividade biologica, promover o crescimento e a saude das plantas e animais e manter a qualidade ambiental. A mudanca na forma e intensidade de uso do solo afeta a sua qualidade e leva a altera…
以硝酸铁和硝酸钴为原料, 柠檬酸为络合剂, 采用溶胶–凝胶法合成具有高红外辐射性能的钴铁氧体, 并考察初始混合溶液pH (pH=1、3、5、7)对CoFe 2 O 4 红外辐射性能的影响。利用FTIR、TG/DSC、XRD、SEM、BET和红外发射率测试等对CoFe 2 O 4 的形成过程、结构、形貌以及红外辐射性能进行表征。结果表明: 不同pH的初始混合溶液所得干凝胶均具有自蔓延燃烧特性, 经600℃煅烧后得到无杂质的尖晶石型CoFe 2 O 4 粉体。研究发现, 初始混合溶液的最佳pH为5, 此时样品8~14 μm波段的红外发射率最高(0.92), 形成以介孔为主的孔结构, 比表面积为65.44 m 2 /g。

Objective To monitor the degradation and bio-safety features of the bioabsorbable iron-based stent planted in the pig pulmonary artery. Methods A total of 19 miniature pigs were randomly assigned into 3 groups.Three cases were assigned as the control group; ten cases were assigned as stent implantation group A with on…
为满足C-ADS 项目建设对超导轮辐腔Spoke021的需求，对Spoke021进行了详细的电磁参数优化。对Spoke021的参数化模型进行参数扫描，针对腔体的关键电磁特征量寻找可能存在的极值，详细分析、解释了优化过程中各个参数发生变化的物理意义。在Spoke021各参数达到最终优化值时，表征腔体性能的两个关键比值分别为：E_p/E_(acc) = 3:14，B_p/E_(acc) = 4:77 mT/(MV/m)。考虑到次级电子倍增(Multipacting，MP)对Spoke021运行中所能达到的性能指标有很重要影响，对腔体的MP进行了建模分析。结果表明，当Spoke021工作在Eacc =10 MV/m情况下，没有发生MP，…
测量了入射能为1.9 ~11.3 keV/u 的O2+ 离子穿过碳膜诱导的前向、后向(分别对应出射表面和入射表面)电子发射产额。实验中，通过改变入射离子的能量和流强，系统地研究了电子能损和离子束流强度对前向、后向电子发射产额的影响。结果表明，在本实验的能量范围内，前向、后向电子发射产额与对应表面的电子能损有近似的正比关系，而与束流强度无关。分析还发现引起后向电子发射的动能阈值约为0.2 keV/u，势能电子发射产额约为1 e-/ion。 We have measured the secondary electron emission yields in forward and backward directions from th…
