This study throws light on utilization of visible light in removal dyes from wastewater using commercial PbCrO4/TiO2(P-25) composite which was prepared by grinding TiO2(P-25) with PbCrO4 to decrease the adhesion properties of PbCrO4. As-prepared catalyst was characterized by DRS, XRD and N2 adsorption–desorption. The morphology was examined by SEM. The photodegradation of rhodamine B (Rh B) produc......  hiện toàn bộ
 A study on the design education method using 3D pen in an era of manufacturing changeSpringer Science and Business Media LLC -  Tập 7  - Trang 461-465 - 2021

With the development of 3D printing technology, there will be a lot of changes in manufacturing. Recently, research on 3D pen using 3D printing technology is increasing. Unlike 3D printing, 3D pen can print products instantly. So, 3D pen will be applied in various fields. In this study, the design education method using 3D pen was studied. The results of this study are as follows. First of all, de......  hiện toàn bộ
 Research on measurement modeling of track and field training load intensity based on wearable nano-equipmentSpringer Science and Business Media LLC -  Tập 7  - Trang 109-117 - 2022

In order to solve the problems of long data collection time, measurement relative error and high time consumption of traditional methods in track and field training, a measurement modeling method of track and field training load intensity based on wearable nano-equipment was proposed. Using the wearable nano-equipment acquisition heart rate, pulse, blood oxygen saturation, such as track and field ......  hiện toàn bộ

Nano-pollutants (NPLTs) have recently raised global concerns due to their possible harmful impact on environment and human health. However, until date, information on the occurrence, fate and toxicity of NPLTs in environment is scant. The knowledge gap can be attributed to the lack of advanced and sophisticated methodologies for the precise detection and characterization of NPLTs at lower concentr......  hiện toàn bộ
 Fabrication of novel AgIO4/TiO2 heterojunction for photocatalytic hydrogen production through direct Z-scheme mechanismSpringer Science and Business Media LLC -  Tập 5  - Trang 1-11 - 2020

In this research, novel AgIO4/TiO2 heterojunctions with high photocatalytic hydrogen production efficiency were fabricated by sonochemical route. XRD, N2-adsorption–desorption isotherm, DRS, PL, XPS and HRTEM analysis are carried out for investigating the physicochemical properties of the photocatalyst. Noticeably, XRS, HRTEM, DRS and PL results reflect the shift in the crystalline diffraction pea......  hiện toàn bộ
