  • Conductive-perovskite LaNiO3 Thin Films Prepared by Using Solution Process for Electrode Application

    • Authors: Nguyen, Quang Hoa; Bui, Nguyen Quoc Trinh (2018)

  • Lanthanum nickel oxide LaNiO3 (LNO) isextensively known as one of typical perovskite-structured materials with metallic conductivity, which is suitable for the electrode application in electronic devices such as transistors or solar cells. Since LNO is a low-cost material and a simple fabrication process, it has been attracted much attention for commercialization. In this paper, we have focused on optimizing the fabrication process of LNO thin films on SiO2/Sisubstrate and Al foil by using asolution process. The crystal structure and surface morphology were characterized by using X-ray diffraction and field-emission scanning electron microscopy (FE-SEM), respectively. It was found tha...

  • Construction of Yeast Pichia pastoris Expressing the Recombinant p53 as a Secreted Protein into Culture

    • Authors: Tran, Thi Thuy Nga; Nguyen, Quang Hoa; Hoang, Van Tuyen; Do, Thi Tuyen; Dinh, Nho Thai (2016)

  • Human p53 protein has been known as a tumor suppressor and described as "the guardian of the genome", referring to its role in conserving stability of genome by preventing mutation. The recent studies on p53 protein expression have demonstrated the important role and effectiveness of exogenous p53 protein in tumor suppression. In the world, the expression of p53 for therapeutically interest was extensively study but in Vietnam it has not been noticed. In the other hand, Pichia pastoris showed a good expression system for many exogenous proteins with a simple cloning work and cheap culture. In this study, codon optimization of gene encoding human p53 protein was performed for suitable ...

  • Fabrication, Characterization of SiO2 Nanospheres and SiO2 Opal Photonic Crystals

    • Authors: Nguyen, Duy Thien; Nguyen, Ngoc Tu; Nguyen, Quang Hoa; Sai, Cong Doanh; Le, Van Vu (2021)

  • In this report, we presented the usage of Stober method to fabricate SiO2 nanospheres and self-assembly method to make SiO2 opal photonic crystals based on the fabricated SiO2 nanospheres. An averaged size of SiO2 nanospheres was controlled by varying concentrations of NH4OH and TEOS. Crystal structure and morphology of particles was investigated by using X-ray diffraction (XRD) and scanning electron microscopy (SEM) techniques. Experimental results showed that SiO2 nanospheres possess amorphous crystal structure with sizes ranged from 150 to 300 nm. The diffuse reflection spectra show the reflection peaks of the SiO2 opal photonic crystals from 410 nm to 520 nm.

  • Solution-processable zinc oxide based thin films with different aluminum doping concentrations

    • Authors: Bui, Nguyen Quoc Trinh; Truong, Dinh Chien; Nguyen, Quang Hoa; Do, Hong Minh (2020)

  • Al doped zinc oxide (AZO) thin films are attempted to be formed on glass substrates via solution processing with 0, 0.5, 1, 2, 3, and 4 at% Al doping concentrations. Analysis of X-ray diffraction patterns and scanning electron microscopy micrographs indicate that the AZO thin films belong to the wurtzite hexagonal structure with (100), (002), (101), (102), (110), (103), (112) and (201) orientations, and show that the grain size of AZO thin films decreases with higher Al doping concentrations. Optical and electrical properties of the AZO thin films are characterized from using a UV/vis spectrometer and a four-probe measurement system, respectively. The AZO thin films obtained have a mi...
