Article Synopsis
  • Diarrheagenic Escherichia coli (DEC) is a group of harmful bacteria causing severe diarrhea in kids in developing countries, especially Vietnam, with limited understanding of their characteristics.
  • In a study of 61 isolates from infants, researchers identified 57 different strains of DEC, with the majority being enteroaggregative E. coli (54.1%) and enteropathogenic E. coli (32.8%), along with some strains of Escherichia albertii.
  • Many of these DEC strains showed genetic traits linked to antibiotic resistance, posing treatment challenges, as up to 65.6% were resistant to ciprofloxacin and 41% to ceftriaxone, indicating the need for ongoing research and

Zeolitic imidazolate framework ZIF-8, a type of metal-organic framework, has diverse applications in multiple catalytic fields due to its outstanding properties. Herein, ZIF-8 photocatalysts with three different morphologies (dodecahedral, pitaya-like, and leaf-like) are successfully synthesized under ambient conditions from zinc salts by altering the volume ratio of methanol and water used as a solvent. The as-synthesized ZIFs have high crystallinity with distinct BET surface areas.

Anionic Congo red dye (CR) is not effectively removed by conventional adsorbents. Three novel biochars derived from agro-waste (Acacia auriculiformis), modified with metal salts of FeCl, AlCl, and CaCl at 500 °C pyrolysis have been developed to enhance CR treatment. These biochars revealed significant differences in effluents compared to BC, which satisfied initial research expectations (P < 0.

The objective of the present study is to investigate removal of cationic dye, rhodamine B (RhB), in water environment using a high-performance absorbent based on metal oxide nanomaterials toward green chemistry. The adsorption of sodium dodecyl sulfate (SDS) onto synthesized alpha alumina (-AlO) material (0) at different ionic strengths under low pH was studied to fabricate a new adsorbent as SDS-modified -AlO material (1). The RhB removal using 1 was much higher than 0 under the same experimental conditions.

In the present study, we investigated the removal of an emerging pesticide lindane from aqueous solution using synthesized aluminum hydroxide Al(OH) (bayerite) nanomaterials with surface modification by an anionic surfactant sodium dodecyl sulfate (SDS). The Al(OH) nanoparticles were characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), Brunauer-Emmett-Teller (BET) and zeta potential. The lindane removal using SDS-modified nano-aluminum hydroxide nanoparticles (SMNAH) achieved removal of up to 93.

Cholera epidemics have been recorded periodically in Vietnam during the seventh cholera pandemic. Since cholera is a water-borne disease, systematic monitoring of environmental waters for Vibrio cholerae presence is important for predicting and preventing cholera epidemics. We conducted monitoring, isolation, and genetic characterization of V.
