ZnO particles were prepared by Au-catalyzed vapor phase transport method on silicon substrate. Scanning electron microscopy（SEM） images show many ZnO particles were formed on the sample surface. They grew up layer by layer along the c-axis, which was confirmed by the results of X-ray diffraction（XRD）. The morphology of ZnO particles is close to hemisphere and its formation process could be seen from the SEM image. The room temperature photoluminescence（PL） measurement revealed a narrow UV emission peak at 3.27 eV and a broad green emission peak at 2.45 eV, which was caused by the near-band-edge and deep-level emissions.

Pancreatic duct adenocarcinoma is one of the most fatal malignancies, with R0 resection remaining the most important part of treatment of this malignancy. However, pancreatectomy is believed to be one of the most challenging procedures and R0 resection remains the only chance for patients with pancreatic cancer to have a good prognosis. Some surgeons have tried minimally invasive pancreatic surgery, but the shortand long-term outcomes of pancreatic malignancy remain controversial between open and minimally invasive procedures. We collected comparative data about minimally invasive and open pancreatic surgery. The available evidence suggests that minimally invasive pancreaticoduodenectomy(MIPD) is as safe and feasible as open PD(OPD), and shows some benefit, such as less intraoperative blood loss and shorter postoperative hospital stay. Despite the limited evidence for MIPD in pancreatic cancer, most of the available data show that the short-term oncological adequacy is similar between MIPD and OPD. Some surgical techniques, including superior mesenteric artery-first approach and laparoscopic pancreatoduodenectomy with major vein resection, are believed to improve the rate of R0 resection. Laparoscopic distal pancreatectomy is less technically demanding and is accepted in more pancreatic centers. It is technically safe and feasible and has similar short-term oncological prognosis compared with open distal pancreatectomy.

A series of perovskite compounds of La1-x-yCaxKyMnO3 was prepared by hydrothermal disproportionation reaction of MnO2. The three oxidation states of manganese（Mn3＋, Mn4＋ and Mn5＋） can stably exist in the compounds. Under room temperature conditions, twice and three times modulated structure produced by the charge ordering can be observed by X-ray diffraction（XRD）, select area electron diffraction（SAED） and high resolution transmission electron microscopy（HR-TEM）. The splits of the diffraction peaks of the single crystals confirmed by synchrotron X-ray diffraction experiment are in accordance with those of the powder sample. The existence of the different oxidation states of Mn3＋, Mn4＋ and Mn5＋ can be considered to be the dominating reason of the complicated room temperature modulated structure.
