Direct current magnetron sputtering was employed to fabricate In-N dual-doped SnO films, with varying concentrations of N in a mixed sputtering gas of N and argon (Ar). The quantity of -substituted O elements in the SnO lattice was confirmed through energy-dispersive X-ray spectroscopy (EDX) and X-ray photoelectron spectroscopy (XPS). A comprehensive investigation of properties of the In-N dual-doped SnO films was conducted using various techniques, including X-ray diffraction analysis, field-emission scanning electron microscopy (FESEM), atomic force microscopy (AFM), ultraviolet absorption spectroscopy, Hall effect measurements, and current-voltage (-) characteristic assessments.

nT4X and nT4M: Novel Time Non-reversible Mixture Amino Acid Substitution Models.

J Mol Evol

January 2025

University of Engineering and Technology, Vietnam National University, 144 Xuan Thuy, Cau Giay, 10000, Hanoi, Vietnam.

One of the most important and difficult challenges in the research of molecular evolution is modeling the process of amino acid substitutions. Although single-matrix models, such as the LG model, are popular, their capability to properly capture the heterogeneity of the substitution process across sites is still questioned. Several mixture models with multiple matrices have been introduced and shown to offer advantages over single-matrix models.

Contamination of retail market meat with extended-spectrum beta-lactamase genes in Vietnam.

Int J Food Microbiol

January 2025

The United Graduate School of Drug Discovery and Medical Information Sciences, Gifu University, Gifu, Japan. Electronic address:

The contamination of retail meat with antibiotic-resistant bacteria poses a substantial public health risk because of the potential spread of these bacteria within communities. The contamination of retail meat with extended-spectrum beta-lactamase (ESBL)-producing bacteria was investigated in four cities in Vietnam using real-time PCR, employing ESBL marker genes. This method provides a more comprehensive assessment of ESBL-producing bacterial contamination in meat samples than culture-based methods because it directly detects resistance genes from the extracted sample DNA.
