| 1 | Effect of surface structure on the catalytic behavior of Ni:Cu/Al and Ni:Cu:K/Al catalysts for methane decomposition显示文摘甲烷分解使用镍,铜,和铝(Ni : Cu/Al ) 并且镍,铜,钾,和铝(Ni : Cu : K/Al ) 修改 nano 催化剂为碳纤维,氢和烃生产被调查了。X光检查光电子光谱学( XPS ),静态的第二等的离子质量 spectrometry ( SSIMS ),热 gravimetric 分析( TGA ), Fourier 变换红外线(英尺红外),第二等的电子显微镜学/X光检查精力散( SEM-EDX ),并且温度规划了解吸附作用( TPD )被用来描绘催化结果的化学。揭示的这些技术在表面形态学和 Ni, Cu,艾尔,和 K 的结构的变化,和形成二金属并且 trimetallic 表面猫有不同的猫的离子的地点离子的种类,在 Ni 上导致了纯碳的 graphitic 形式的生产, Cu/Al 催化剂。K 的增加在产品选择和催化剂系统的反应上有显著效果。K 增加在表面上限制碳的形成并且而没有 K,没有烃在样品上被生产,在催化反应期间增加氢和 C 2, C 3 烃的生产。这研究完全印射有两个系统的催化行为的修改表面结构和它的关系。这个过程在 Ni 上为碳纤维和氢的生产提供一条灵活线路: 与 Ni 上的烃一起的 Cu/Al 催化剂和氢: Cu : K/Al 催化剂。生产的碳纤维为直径尺寸和墙结构决心用一台传播电子显微镜(TEM ) 被想象。生产的氢是公司 x 释放,它能在燃料房间系统直接被使用。有 Ni 和 K 的 Cu 和它的转变和相互作用的增加的效果为公司 / 公司 2 的生产负责免费的氢,因此生产一个环境友好干净精力。 | S.Tajammul Hussain Sheraz Gul Muhammed Mazhar Dalaver H.Anjum Faical Larachi | 2008 | Journal of Natural Gas Chemistry2008，17，4： | 1 |
| 2 | 氧化硅掺杂对硫酸化氧化锆酸性中心浓度和强度的提高显示文摘用氧化硅掺杂硫酸化氧化锆可以增强硫酸化氧化锆的酸性. 以413~453 K下甲醇液相脱水为模型反应考察了改进催化剂的性能. 结果表明,在掺杂和未掺杂氧化硅的硫酸化氧化锆催化剂上甲醇均相继脱水生成二甲醚和乙烯. 在掺杂了氧化硅的催化剂上还有一定量的丙烯生成,而未掺杂氧化硅的催化剂上则没有丙烯生成. | S. Tajammul HUSSAIN Muhammad MAZHAR Sheraz GUL | 2007 | 催化学报2007，28，7： | 1 |
| 3 | Activation of neurogenesis in the hippocampus is a novel therapeutic target for Alzheimer's disease显示文摘The pathologies associated with age-related brain dysfunction,including Alzheimer's disease(AD),Parkinson's disease,Lewy body dementia,and vascular dementia,often share similarities across multiple diseases.1 While various factors,such as amyloidβ,Tau protein,α-synuclein,chronic inflammation,and impaired cerebral microcirculation have been suggested as potential therapeutic targets,addressing a single factor is unlikely to be sufficient in preventing or treating age-related brain dysfunction.Drawing from these observations. | Akihiko Taguchi Yuka Okinaka Akiko Takeda Takayuki Okamoto Johannes Boltze Carsten Claussen Sheraz Gul | 2023 | Neuroprotection2023，1，2： | 0 |
| 4 | Manipulating magnetic anisotropies of Co/MgO(001) ultrathin films via oblique deposition显示文摘We present a systematic investigation of magnetic anisotropy induced by oblique deposition of Co thin films on MgO(001) substrates by molecular beam epitaxy at different deposition angles,i.e.,0?,30?,45?,60?,and 75?with respect to the surface normal.Low energy electron diffraction(LEED),surface magneto–optical Kerr effect(SMOKE),and anisotropic magnetoresistance(AMR) setups were employed to investigate the magnetic properties of cobalt films.The values of in-plane uniaxial magnetic anisotropy(UMA) constant Ku and four-fold magnetocrystalline anisotropy constant K1 were derived from magnetic torque curves on the base of AMR results.It was found that the value of Ku increases with increasing deposition angle with respect to the surface normal,while the value of K_1 remains almost constant for all the samples.Furthermore,by using MOKE results,the Ku values of the films deposited obliquely were also derived from the magnetization curves along hard axis.The results of AMR method were then compared with that of hard axis fitting method(coherent rotation) and found that both methods have almost identical values of UMA constant for each sample. | Syed Sheraz Ahmad 何为 汤进 张永圣 胡泊 叶军 Qeemat Gul 张向群 成昭华 | 2016 | Chinese Physics B2016，25，9： | 0 |
