Objectives: Trace elements zinc and copper are effective in wound and fracture healing. In this prospective study, correlations between mangled extremity severity score (MESS) and mangled extremity syndrome index (MESI) and serum zinc and copper levels were investigated in trauma patients.
Methods: Seventeen trauma patients (11 females, 6 males; mean age 41.6 years; range 11 to 73 years) were evaluated with respect to MESS and MESI scores. On the seventh day of trauma, serum samples were obtained to determine zinc and copper levels by atomic absorption spectrophotometry.
Results: Serum levels of zinc and copper showed significant negative correlations with both MESS (r=-0.65 and r=-0.76, respectively) and MESI (r=-0.83 and r=-0.77, respectively) scores (p<0.05).
Conclusion: The severity of trauma is associated with significant decreases in serum levels of trace elements. Thus, trace element supplementation may be an important aspect of treatment in trauma patients.

A comparative pot study was performed to assess the toxic effects of copper (Cu) and/or zinc (Zn) contaminated wastewater (WW) irrigation on the growth, physiology, and element concentration of wheat grown for two months. The treatments included irrigation with uncontaminated wastewater (WW) as control, Cu-contaminated WW (CuWW), Zn-contaminated WW (ZnWW), and Cu + Zn contaminated WW (CuZnWW) in a completely randomized design. Compared to ZnWW, irrigation with CuWW or CuZnWW had severe effects on growth, physiology, and mineral absorption by wheat.

The aqueous zinc metal battery holds great potential for large-scale energy storage due to its safety, low cost, and high theoretical capacity. However, challenges such as corrosion and dendritic growth necessitate controlled zinc deposition. This study employs epitaxy to achieve large-area, dense, and ultraflat zinc plating on textured copper foil.

Zinc (Zn)-based batteries have been persistently challenged by the critical issue of inhomogeneous zinc deposition/stripping process on substrate surface. Herein, we reveal that zinc electrodeposition behaviors dramatically improved through the introduction of highly zincophilic copper oxide nanoparticles (CuO NPs). Strong electronic redistribution between Zn and CuO explains the high Zn affinity on CuO, with negligible nucleation overpotential.

Mechanoluminescence platforms, combining phosphors with elastic polymer matrix, have emerged in smart wearable technology due to their superior elasticity and mechanically driven luminescent properties. However, their luminescence performance often deteriorates under extreme elastic conditions owing to a misinterpretation of polymer matrix behavior. Here, we unveil the role of the polymer matrices in mechanoluminescence through an interface-triboelectric effect driven by elasticity, achieving both high elasticity and brightness.

Background: The biopharmaceutical industry is increasingly interested in the analysis of trace metals due to their significant impact on product quality and drug safety. Certain metals can potentially accelerate the formation of degradants or aggregates in biotherapeutic proteins, leading to drug product quality concerns. A better understanding of metal-mAb interactions would aid in the development of purification processes and formulations, thereby ensuring better drug quality and safety.
