Background: In the lower Mekong Basin and coastal zones of Southern Vietnam, forests dominated by the genus have two notable features: most have been substantially disturbed by human activity and can now be considered as degraded forests; and most are subject to acute pressures from climate change, particularly in regards to changes in the hydrological and sodicity properties of forest soil.
Results: Data was collected and analyzed from five typical stands including: (1) primary forests on sandy soil (VS1); (2) regenerating forests on sandy soil (VS2); (3) degraded secondary forests on clay soil with peat (VS3); (4) regenerating forests on clay soil with peat (VS4); and (5) regenerating forests on clay soil without peat (VS5). Carbon densities of VS1, VS2, VS3, VS4, and VS5 were found to be 275.98, 159.36, 784.68, 544.28, and 246.96 tC/ha, respectively. The exchangeable sodium percentage of forests on sandy soil showed high sodicity, while those on clay soil varied from low to moderate sodicity.
Conclusions: This paper presents the results of an assessment of the carbon stocks and sodicity tolerance of natural communities in Southern Vietnam, in order to gather better information to support the improved management of forests in the region. The results provide important information for the future sustainable management of forests in Vietnam, particularly in regards to forest carbon conservation initiatives and the potential of species for reforestation initiatives on degraded sites with highly sodic soils.

The primary goal of the current work was to construct pH-sensitive nano and microcomposite hydrogel beads based on alginate (AL), carboxymethyl cellulose (CMC), biochar (BC), and two Moroccan clays: Ghassoul (swelling SW) and red (not swelling NSW) nano and microhybrid. The adsorbents, SW + AL, SW + AL + BC, SW + AL + CMC, NSW + AL, NSW + AL + BC, NSW + AL + CMC, AL, and AL + CMC were prepared for the adsorption of the antibiotic sulfadiazine (SDZ). The test samples were characterized using a variety of techniques, including X-Ray Diffraction (XRD), IR spectroscopy (FT-IR), and scanning electron microscopy (SEM), with the molecular structures of the studied additives geometrically optimized using the DFT/B3LYP method and the function 6-311G(d).

Chemical weathering of lithologies with high geochemical backgrounds such as black shale has been proposed to be a critical source for toxic elements in soil and water systems. However, mechanisms controlling the release, migration and enrichment of toxic elements during black shale weathering are poorly understood. This study utilized a suite of micro analytical techniques such as TESCAN integrated mineral analyzer (TIMA), scanning electron microscopy-energy dispersive X-ray spectroscopy (SEM-EDS), X-ray photoelectron spectroscopy (XPS) and electron micro-probe analysis (EMPA) to elucidate the intimate relationship between mineralogical transformations and elemental behaviors from profile scale to mineral scale.

Phosphorus (P) movement in soils is influenced by flow velocities, diffusion rates, and several soil characteristics and properties. In acidic soils, P is tightly bound to soil particles, reducing its availability to plants. Organomineral fertilizers combine organic matter with mineral nutrients, enhancing P fertilization efficiency, and reducing environmental impacts.

Background: The 3D printing of macro- and mesoporous biomimetic grafts composed of polycaprolactone (PCL) infused with nanosized synthetic smectic clay is a promising innovation in biomaterials for bone tissue engineering (BTE). The main challenge lies in achieving a uniform distribution of nanoceramics across low to high concentrations within the polymer matrix while preserving mechanical properties and biological performance essential for successful osseointegration.
Methods: This study utilized 3D printing to fabricate PCL scaffolds enriched with nanosized synthetic smectic clay (LAP) to evaluate its effects on structural, chemical, thermal, mechanical, and degradative properties, with a focus on in vitro biological performance and non-toxicity.

Acrylamide has high hydrophilic properties due to the presence of hydrophilic amide functional groups and is frequently used to synthesize superabsorbents. However, the toxic and carcinogenic properties of acrylamide have caused environmental concerns. The main goal of this paper is the synthesis of superabsorbent with high water absorption from biodegradable and biocompatible cellulose polymer containing amide groups in the backbone of it instead of grafting harmful acrylamide monomers to cellulose.
