| 1 | Fabrication and near-infrared optical responses of 2D periodical Au/ITO nanocomposite arrays显示文摘Two-dimensional(2D) periodical Au and indium tin oxide(ITO) nanocomposite arrays have been fabricated based on a self-assembled nanosphere lithography technique. A button-shaped Au nanoparticle was formed on each hollow hemisphere-shaped ITO shell. Importantly, the underlying formation mechanism during the thermal treatment has been thoroughly explored by comparing structures resulting from different deposition conditions in detail. Compared to the Au nanoparticle arrays without ITO shells, the Au/ITO nanocomposite arrays showed a stronger localized surface plasmon resonance effect and higher absorption in the near-infrared(NIR) region, benefiting from the free-electron interaction enhancement between Au and ITO. The nonlinear optical properties were investigated using a modified femtosecond intensity-scan system, and the results demonstrated Au/ITO nanocomposite arrays with a remarkable two-photon absorption saturation effect for femtosecond pulses at 1030 nm. The versatile NIR optical responses indicate the great potential of the elaborately prepared 2D periodical Au/ITO nanocomposite arrays in many applications such as solar cells, photocatalysis,and novel nano optoelectronic devices. | ZHENGYUAN BAI GUIJU TAO YUANXIN LI JIN HE KANGPENG WANG GAOZHONG WANG XIONGWEI JIANG JUN WANG WERNER BLAU LONG ZHANG | 2017 | Photonics Research2017，5，4： | 2 |
| 3 | Serum metabolic effects of corn oligopeptides with 7-day supplementation on early post-surgery primary liver cancer patients: a double-blind randomized controlled trial显示文摘Background:Liver cancer as the main leading cancer has caused heavy burdens globally.The prognosis of liver cancer is closely related with postoperative nutrition support.Corn oligopeptides(COPs)are protein hydrolysates produced by enzymatic treatments,which have shown potential bioactivities,such as inhibiting angiotensin I-converting enzyme,resisting lipid peroxidation and anti-oxidant.However,the correlation between COPs and liver cancer patients is still unknown and the potential mechanism of COPs on liver cancer is unclear as well.The aim of this study was to assess effects of 7-day intervention of COPs after surgery on liver function and serum metabolic profiles of liver cancer patients.Methods:Patients were assigned into COPs intervention group(n=50)and control group(n=91)for 7 days.Investigations were scheduled at 1st day and 7th day after liver resection surgery respectively,mainly including anthropometric,biochemical indexes and liquid chromatography-mass spectrometry(LC/MS)analysis.Results:Seven-day supplementation of COPs on early post-surgery liver cancer patients down-regulated levels of alanine aminotransferase,aspartate aminotransferase,total bilirubin,direct bilirubin and up-regulated prothrombin time activity and prealbumin levels.LC/MS analysis revealed metabolic signatures including regulation of 16 metabolites,which was closely related with two metabolic pathways(nicotinate and nicotinamide metabolism,fatty acid metabolism).Conclusions:COPs supplementation has displayed the potentials on alleviating the injury of liver function and it may be due to regulation of fatty acid metabolism,nicotinate and nicotinamide metabolism,lipid peroxidation and anti-inflammatory action.More researches are warranted in future to confirm the exact mechanisms. | Weiqi Rong Hui Xia Kai Zhang Yihan Zhang Changcheng Tao Fan Wu Liming Wang Hong Zhang Guiju Sun Jianxiong Wu | 2022 | Hepatobiliary Surgery and Nutrition2022，11，6： | 0 |
