The swine farming has a significant potential for biogas emissions and is a substantial contributor to greenhouse gas emissions within Vietnam's agricultural sector. This study was conducted to determine the total amount of CH4, and CO2 (eq) released from mature management activities and emission coefficients of CH4 and CO2 (eq) at different swine farms in Northern, Central and Southern regions, using tier 1 and tier 2 according to IPCC method.

In this study, we used the reliable GC-FID/MS technique to analyze the methyl ester derivatives of 37 different kinds of fatty acids. The results showed that high saturated fat concentration in all samples was mostly palmitic acid, whereas the low unsaturated fatty acid content in the cis form was primarily oleic acid and linoleic acid. The amount of monounsaturated and polyunsaturated fats is quite low.

In this work, gold nanorods (AuNRs) with well-controlled aspect ratios were prepared using a modified seedgrowth method and covered by TiO2 layers through the hydrothermal reaction to improve stability. Integrating TiO2 with plasmonic rod-like gold nanoparticles could enhance their photo activity by the local surface plasmon resonance (LSPR) effect. AuNRs aspect ratios were controlled by varying the amount of seed solution, reducing agents, surfactant (CTAB), and titanium (IV) but oxide.

Vietnam’s young plastic industry plays an important role in economic development recently. Plastic recycling (PR) is necessary to help companies economically manage their input materials and reduce the amount of solid waste disposal in its surroundings. Improper management of PR activities causes some environmental pollution problems and greenhouse gases (GHGs) released from these activities are core concerns.

We have carried out studying for antioxidant activity of 58 extracts prepared from vegetables and fruits in Viet Nam by three methods including DPPH and H2O2 scavenging activity assays and determination of total flavonoid content (TFC). Ethanol extract of Tamarind seed (NTBT-17), Grape seed (NTBT-19) and Mangosteen peel (TNB-10) showed high amount of TFC which is 848.8, 655.9 and 422.9 mgQE/100g, respectively.

The objective of this project was to develop \(Ti{O_2}\) based multifunctional substrates through silver decoration, while simultaneously enhancing the photocatalytic performance of \(Ti{O_2}\) in the substrate. Employing Ag nanoparticles introduced additional functionality to the system, namely surface-enhanced Raman scattering (SERS), thus enabling the detection of trace amounts of organic molecules prior to their degradation, all with the same substrate.

Human placental JEG-3 cells conserve a high P450 aromatase activity and are therefore suitable to evaluate how contaminants may interfere with the routes involved in estrogen synthesis during pregnancy. This has been traditionally assessed by measuring aromatase activity through the amount of tritiated water (3H2O) formed during the aromatization of 1β-3H-androst-4-ene-3,17-dione (3H-AD).

Mechanochemical activation and steam-assisted interzeolite transformation offer a simple, fast and cost-efficient synthesis route to gmelinite (GME) zeolite. The use of faujasite (FAU) as the parent zeolite precursor facilitates the reaction and results in high yields of high-quality GME in less than 20 h under optimized conditions. The accessible porosity and amounts of stacking-faults were determined by N2 physisorption and XRD analysis, respectively.
