Removability

In this study, a composite material between MnFe2O4 and activated carbon from coffee husks (MFO/AC) was synthesized using co-precipitate and hydrothermal methods to remove ammonium from aqueous solutions. The characteristics of MFO/AC were characterized and evaluated by scanning electron microscopy (SEM) and Fourier transform infrared spectra (FTIR).

Teeth displaced from their alveolar bone can be replanted if properly handled and stored in suitable environments. To help minimize the failure of reimplantation, teeth should be preserved in a storage environment that is initially free of bacteria. Research objective: Evaluating the morphology of bacteria on the periodontal ligament cells in different storage environments at various time points after the teeth have been removed from the alveolar bone using Gram staining.

Polyethyleneimine (PEI) is a novel polymer that contains multiple amine groups that are suitable for chelation with many heavy metal ions (HMI). Anchoring PEI onto the surface of a solid substrate has been widely adopted to develop adsorbent materials with the hope of combining the HMI chelating ability of PEI with the heterogeneity of the substrate.

Air pollution is getting worse in Viet Nam in recent years, particularly in big cities. The most important source of pollution are traffic and industrial activities. The paper "A Review on Current Status of Urban Air Pollution in Ho Chi Minh city and Ha Noi" reviews air pollution situation in Ho Chi Minh city and Ha Noi. We also recommend policies to tackle the problem: (i) upgrade the national air quality standard, (ii) install systematic and high-quality network of monitor stations, and (iii) remove means of transport that unmet emission regulations.
