Summary: Powdered ostracod carapace of the species (Herpetocypris brevicaudata) loaded on Amberlite XAD-4 resin was used as a biosorbent for determining concentrations of trace metal ions in water samples. Optimum pH values for Cu(II), Co(II) and Mn(II) were around 10.0. The sorption capacity of AXAD-4 resin loaded with H. brevicaudata was evaluated for Cu(II), Co(II) and Mn(II) with satisfactory results.

Summary: Renewable energy requires efficient storage devices for balancing electricity demand and supply. In this study, a cobalt sulfide electrode modified with different metals, such as manganese and copper, demonstrated enhanced performance in terms of specific capacitance and cycling stability. Among the electrodes tested, Mn-CoS-3/NF exhibited the best rate capability and capacitance retention, attributed to its unique nanostructure and low internal resistance.

Summary: Studies have shown that coffee infusions contain trace elements with antioxidant activity such as manganese, zinc, copper, iron, fluoride, chromium, and cobalt, which can contribute to meeting certain nutritional requirements. The origin of coffee beans and the type of water used may impact the mineral content in infusions, while the brewing method does not seem to have a significant role. Further research in this area is needed to explore the bioavailability of these micronutrients in coffee.

Summary: Due to the low efficiency of catalytic oxidation of ammonium and manganese in high alkalinity groundwater by manganese oxide filter column, the effect of doping copper (Cu) and cobalt (Co) on catalytic activity was investigated. The results showed that low Cu doping increased the ammonium removal efficiency while decreasing the manganese removal efficiency. Low Co doping was beneficial to the start-up period of the filter column. The study also revealed the formation of calcium carbonate on the surface of the filter media due to the high alkalinity of the water, which was found to affect the catalytic activity of manganese oxide filter media.

Summary: A family of copper(ii)/manganese(ii) new clusters with different formulas have been successfully synthesized and structurally and magnetically characterized. The reduced magnetization studies show that the magnetic anisotropy of these systems is very small. However, dynamic magnetic studies confirm the slow relaxation of these systems despite their quasi-isotropic nature, expanding the range of non-anisotropic slow relaxing molecules.

Summary: Reactive flash sintering is an effective method for densifying and synthesizing ceramic materials, but the predictive capability of the BBR model for phase transformations during the process is limited. CuO reduction and Mn(2)O(3) reduction demonstrate the challenges of predicting phase transformations due to local, stochastic current flow and localized heating. Understanding and engineering the complex thermal profile that results from these sources of inhomogeneity can be beneficial for optimizing reaction kinetics.

Summary: Understanding the effects of different fertilization regimes on soil phosphorus forms, it was found that organic fertilizer can improve the availability of soil phosphorus and reduce its transformation to stable forms. XANES analysis revealed that the accumulated phosphorus in different treatment was dominated by different phosphate species. Soil organic matter, organic-bound iron, and alumina oxide played significant roles in the transformation of phosphorus forms.

Summary: This study investigated the availability of organic phosphorus compounds adsorbed onto soil minerals and their uptake by plants. The results showed that the availability and uptake of adsorbed organic phosphorus compounds varied depending on the type of mineral and organic phosphorus compound. The uptake of phosphorus from adsorbed organic phosphorus compounds was influenced by the available phosphorus concentration in the rhizosphere rather than the binding strength of the compounds to the mineral surface.

Summary: Lubumbashi, the capital of copper mining in DR Congo, has been known for its rich mineral resources for over a decade. However, the mining activities have led to pollution of soil, water, and vegetables in urban gardens, posing serious health risks. The study found that the soils had varying levels of metal contamination, with some exceeding the WHO thresholds. Irrigation water used in the gardens also contained high levels of toxic metals. Furthermore, the vegetables grown in these gardens had metal contents that exceeded the WHO standard for human consumption. It is important to adopt more sustainable techniques to reduce the transfer of metals from soil to plants.

Summary: This study aimed to assess the performance of three machine learning algorithms (PLS, SVM, and RF) in predicting soil properties and classes related to salt-affected soils. The SVM and RF regressions performed well in estimating soil electrical conductivity and exchangeable sodium percentage, respectively. The RF algorithm was superior in predicting the salt-affected soil categories. Soluble sodium was found to be the most relevant variable for the predictions. These models can contribute to the monitoring and management of salt-affected soils in the study area.

Summary: Copper smelting in Penga Penga has caused soil contamination with trace metals, leading to trace metal ingestion among residents and difficulties in planting trees. Despite this, planting trees in former household dumps or using amendments has allowed fruit provision in some residences. A survey was conducted to assess the effectiveness of the planting processes on trace metal content in fruits and leaves of Mangifera indica L. and Syzygium guineense (Willd) DC. Results showed higher metal concentrations in Penga Penga's rhizosphere, with a higher percentage of samples exceeding FAO and WHO thresholds compared to Kalebuka. However, the bioconcentration factor values were below 1, indicating the effectiveness of the process in reducing metal translocation to leaves and fruits. Safe weekly consumption limits were also determined for each species. These findings provide valuable insights for scaling up tree planting in Penga Penga.
