Application of MIKE 21 FM modelling to simulate the water quality at the coastal area Đình Vũ
Tập 1 Số T4 - Trang 282-292 - 2017
The MIKE 21 FM model, developed by the Danish Hydraulic Institute, is a distributed system model that is used in hydrological calculations, water quality simulation, sediment transport calculations, resources and water environment in rivers, estuaries, coastal areas, and seas... This paper is an initial step in setting and establishing a set of model's parameters for simulating contaminant transpo......
Chemical constituents of Euphorbia tirucalli L.
Tập 2 Số 5 - Trang 76-82 - 2019
This article was retracted on 15 December 2021 by authors.
Euphorbia tirucalli has not been chemically studied much in Vietnam. This research described the isolation and elucidation of compounds isolated from the plant collected in Binh Thuan. Multiple chromatographic methods were applied, including normal phase silica gel column chromatography and thin-layer chromatography. Seven compoun......
Inventory and mapping the air emissions from transportation activities in Ho Chi Minh city
Tập 3 Số 2 - Trang 100-114 - 2019
Ho Chi Minh City plays a role as a leading economic and social center in the South of Vietnam, together with the urbanization, transportation system is being rapidly developing, resulting in an increase in emissions from these activities, and worsen the quality of the city. Therefore in this study, emission inventory for transportation has been conducted using the EMISENS model and then using GIS ......
Investigating and optimizing a method to determine atmospheric mercury for application in Ho Chi Minh City, Viet Nam
Tập 7 Số 1 - Trang 2552-2560 - 2023
Mercury (Hg) is a toxic of global concern due to its bioaccumulation in the environment and the atmosphere which is an important environment in the biogeochemical cycle of Hg. IO-5 method (US-EPA) is the most common analysis method to measure the concentration of atmospheric Hg. However, few studies have been done in tropical monsoonal areas such as Ho Chi Minh City (HCMC). This paper reported the......

Petrographic characteristics and zircon UPb geochronology of granitogneiss rocks in the Chu Lai - Kham Duc area (Quang Nam province)
Tập 1 Số 6 - Trang 258-272 - 2018
The early Palaeozoic granitogneiss association in the Chu Lai - Kham Duc area (Quang Nam) is a large area of hundreds of km2, along southern of the East – West ductile deformation zones (Tam Ky – Phuoc Son fault zone), which is studied in detail in different geologic maps scales by the geologists, which is named Chu Lai complex. The five samples studied in detail are composed mainly of granitognei......
Preparation of silica/carbon composite from rice husk and its electrochemical propertives as anode material in Li-ion batteries
Tập 4 Số 4 - Trang 767-775 - 2020
Rice husk is a common agricultural waste and an abundant source in Viet Nam. In terms of composition, rice husk is a silica-rich material (SiO2) so it can be used to prepare negative electrode materials for rechargeable Li-ion batteries. Recent processes of synthesizing the silica materials for the rechargeable batteries are often complex, expensive, and energy-intensive. In this study, KOH was us......

Synthesis and evaluation of biological activities of two belinostat analogs bearing fluorine at the CAP
Tập 7 Số 1 - Trang 2522-2531 - 2023
Histone deacetylase enzymes are overexpressed in many types of hematologic malignancies (acute myelogenous leukemia, myelofibrosis, cutaneous T-cell lymphoma, and Hodgkin lymphoma) and their inhibition of HDACs could result in the inhibition of cell proliferation and induction of apoptosis. Thus, HDAC inhibitors are candidates of anticancer drug development. Belinostat is a histone deacetylase inh......

Microplastic pollution in clam (Meretrix Lyrata Sowerby, 1851) at Mekong Delta river, Vietnam
Tập 5 Số 3 - Trang 1443-1454 - 2021
The problem of microplastic pollution (<5 mm) is becoming one of the biggest challenges facing countries. One of the problems is the export value of seafood products. Therefore, to assess the microplastic accumulation in clam (Meretrix lyrata), this study investigated the concentration of microplastics (MPs) in clam and their habitat in four clam culture beds (Tan Thanh, Ba Tri, Ganh Hao, and B......
Preparation of magnetic iron Oxide coated on the surface of Cellulose nanocrystals by in-situ coprecipitation process
Tập 3 Số 4 - Trang 271-278 - 2020
This study reported a single-step method for the fabrication of magnetic cellulose nanocrystals (MGCNCs) by coprecipitation iron oxide nanoparticle onto cellulose nanocrystals (CNCs). Cellulose nanocrystals (CNCs) were derived by hydrochloric acid hydrolysis (HCl 6 M, 25 mL/g cellulose) in the optimum condition at 90 °C for 90 min. Pure cellulose was isolated from Nypa fruticans branches, a popula......

Aminolysis of poly(ethylene terephthalate) waste bottle with tetra/hexamethylene diamine and characterization of alpha, ohmega-diamine products
Tập 1 Số T2 - Trang 101-113 - 2017
The aminolysis of poly(ethylene terephthalate) (PET) waste bottle with excess amount of aliphatic diamines, such as tetramethylenediamine (TMDA) and hexamethylenediamine (HMDA) without catalyst has been carried out. Each trimers and pentamers in the obtained products were isolated and characterized by FTIR, NMR, HPLC methods. Although an excess of diamine was employed, longer blocks of oligomers w......
