background: safety and efficacy of the synthetic antioxidants used in the food industry are frequently questioned because such antioxidants are unstable and highly volatile, therefore, interest in finding naturally occurring antioxidants that have the potential to protect human beings from damage induced by oxidative stress has intensified. objective: bioactivities of thymus daenensis and aneth...

Positive electrodes with high energy densities for Lithium-ion batteries (LIB) almost exclusively rely on toxic and costly transition metals. Iron based voltage spinels can be feasible alternatives, but the phase stabilities optimal chemistries LIB applications are not fully understood yet. In this study, LiFe x Mn 2-x O 4 = 0.2 to 0.9 were synthesized by solid-state reaction at 800 °C. High-re...

Spintronic terahertz (THz) emitters based on the inverse spin Hall effect in ferromagnetic/heavy metal (FM/HM) heterostructures have become important sources for THz pulse generation. The design, materials, and control of these interfaces at nanometer level vital to engineer their emission properties. In this work, we present studies optimization such structures through a multi-pronged approach...

This review tries to illuminate how the bacterium Cupriavidus metallidurans CH34 is able to allocate essential transition metal cations to their target proteins although these metals have similar charge-to-surface ratios and chemical features, exert toxic effects, compete with each other, and occur in the bacterial environment over a huge range of concentrations and speciations. Central to this...

Bimetallic nanoparticles (NPs) are complex systems with properties that far exceed those of the individual constituents. In particular, association a noble metal and first-row transition attracting increasing interest for applications in catalysis, electrocatalysis, magnetism, among others. Such objects display rich structural chemistry thanks to their ability form intermetallic phases, random ...
