Abstract:
... The synergistic effect of magnetic and dielectric materials makes this kind of composite as an ideal microwave absorber. So far, composite absorbing materials of Fe₃O₄ and carbon have been extensively studied and achieved excellent absorption properties. However, this type of absorber always has the problem of narrow effective absorption band (RL ≤ −10 dB). In this article, we have prepared 3D (Fe ...

Abstract:
... Fingermarks and DNA are valuable traces in forensic investigations potentially allowing for the identification of the source of the trace or highlighting a link between a touched object and an individual. These traces are often latent and need to be detected before recovery. While a number of validated methods exist for fingermark detection, no routine method is in place for the detection of DNA. ...

The thermodynamic analysis revealed that by controlling solution pH in the range from 14.30 to 16.78 at 25 °C, basic zinc sulfate can be converted to ZnO₂²⁻ instead of Zn(OH)₂, while Cd will enter into alkaline leaching residue as a hydroxide. It is feasible to leach ...

Abstract:
... Toxicity of ZnO nanoparticles (NPs) are often related to the release of Zn²⁺ ions due to their dissolution. Studies also suggest that the toxicity of ZnO NPs cannot be solely explained by the release of Zn²⁺ ions; however, there is a lack of direct evidence of ZnO particulate effects. This study compared the acute toxicity of ZnO NPs and ZnSO₄ following intranasal exposure using a combination of m ...

The plated Pd significantly enhances the degradation rate of PBDEs by ZVZ at the optimum loading of 1% by weight. In the Pd/ZVZ system, very few lower BDEs were accumulated during the degradation of 2,2′,4,4′- tetrabromodipheny ...
