方案详情:
mdea脱碳液的泡高和消泡时间测定
HSY-6538A MDEA溶液泡沫趋势试验器(4孔)
HSY-6538 MDEA溶液起泡趋势试验器(2孔)
本仪器用于按SY/T6538规定的要求,测定配方型选择性脱硫溶剂在氮气规定条件下通过一定体积的试样,测定溶液泡沫高度和稳定性。
测试原理:氮气在规定的条件下通过一定体积的试样,测定溶液泡沫高度和稳定性。
操作步骤:
1、打开恒温水浴,控制水浴温度在30℃±0.1℃。
2、将脱硫溶剂配成40%(W)的水溶液。当水浴达到预定温度时,加入h1=100mm高的试样于发泡管中,一并放入恒温水浴,恒温10min。
3、氮气通过气体流量计后经过发泡管,流率达到 250mL/min 并稳定后开始记时。通气 5min,停止通气,记录泡沫高度 h2(液面最终泡沫高度与初始溶液高度之差)及消泡时间(停气后记时,泡沫刚刚破灭见到清液止)。

文献名: Structural, morphological and optical properties of Bi NPs obtained by laser ablation and their selective detection of L-cysteine 作者: Ramon Gabriel Teixeira Rosaa, Celso de Araujo Duartea , Wido Herwig Schreinera, Ney Pereira Mattoso Filhoa, Arandi Ginane Bezerra Jr.b, Andersson Barisonc, Fernanda Maria Marins Ocamposc a Departamento de Física, Universidade Federal do Paraná Centro Politécnico, CP 19044, 81531-990 Curitiba (PR), Brazil b Departamento Acadêmico de Física, Universidade Tecnológica Federal do Paraná, 80230-901 Curitiba (PR), Brazil c Departamento de Química, Universidade Federal do Paraná Centro Politécnico, CP 19081, 81531-990 Curitiba (PR), Brazil 摘要:In the present work we show the results of the investigation of the properties of bismuth nanoparticles (NPs) obtained by the laser ablation in water. The samples were characterized by various techniques: UV/vis spectroscopy, dynamic light scattering, transmission electron microscopy, X-ray photoelectron spectroscopy, X-ray diffraction, nuclear magnetic resonance and zeta potential. The NPs were metallic and surface oxidated, exhibiting absorption peak at 257 nm due to the surface plasmon resonance. The interaction between the NPs and various amino acids was studied and revealed a selective sensibility to cysteine on a range of concentration from 80 to 720 μM, which we attribute to a dimerization of cysteine to cystine probably complexed to the nanoparticle surface by electrostatic interactions, leading to the modification of the NP absorption spectrum. 关键词:Bismuth; Nanoparticles; Laser ablation; Cysteine

双相不锈钢的增强纳米压痕应用
Using Bruker’s Hysitron PI 88 SEM PicoIndenter equipped with tilt and rotation stages in conjunction with the QUANTAX EBSD system enables a more robust characterization of metallic materials by combining high resolution phase and grain orientation mapping capabilities with targeted nanomechanical property measurements. This combination could also be used to extend the scope of research related to other advanced textured, anisotropic, or multi-phase materials.
