Magnesium is generally known to degrade in aqueous environments by an electrochemical reaction.The corrosion products of magnesium include hydrogen gas,Mg^(2+),and Mg(OH)_(2).Here,we summarize the published literature describing the corrosion characteristics of magnesium,and the antitumor properties of magnesium-associated corrosion products,aiming to induce the therapeutic properties of magnesium and magnesium alloys in solid tumors.The therapeutic potential of corrosion products of magnesium is enormous.Hydrogen gas exhibits antioxidant and anti-inflammatory properties,which amount to potential anti-tumor characteristics.Mg(OH)_(2),which creates a localized alkaline microenvironment,represents a second approach for anti-tumor therapy with magnesium metal.Upregulated concentrations of Mg^(2+)ions in the local tumor microenvironment remodelling are considered a third approach for anti-tumor therapy.Therefore,we speculate about the different physical forms of magnesium that could create an anti-tumor microenvironment upon tumor interventional therapy,a technique that precisely places anti-tumor implants like particles and stents.Finally,we present our viewpoints on the potential use of magnesium in diverse solid tumor therapies to inhibit tumor progression. 展开更多

Layered double hydroxides(LDHs)have a special structure and atom composition,which are expected to be an excellent electromagnetic wave(EMW)absorber.However,it is still a problem that obtaining excellent EMWabsorbing materials from LDHs.Herein,we designed heterostructure NiCo-LDHs@ZnO nanorod and then subsequent heat treating to derive NiCo@C/ZnO composites.Finally,with the synergy of excellent dielectric loss and magnetic loss,an outstanding absorption performance could be achieved with the reflection loss of−60.97 dB at the matching thickness of 2.3 mm,and the widest absorption bandwidth of 6.08 GHz was realized at 2.0 mm.Moreover,this research work provides a reference for the development and utilization of LDHs materials in the field of microwave absorption materials and can also provide ideas for the design of layered structural absorbers. 展开更多

The reasonable design of the composition of the composite materials is of great significance to optimized the electromagnetic(EM)wave absorption performance.Herein,the Ni/NiO@C hybrid composites with tunable Ni proportion were successfully synthesized through a two-step process.With the assistance of X-ray diffraction with refinement treatment,the specific proportion of Ni of as-obtained hybrid composites could be obtained.Employing controlling calcination time to adjust the Ni content of Ni/NiO@C hybrid composites,it has been found that the composite carbonized at 500℃exhibited remarkable EM wave absorption with the minimum reflection loss(RLmin)of-49.1 dB at 4.9 mm and the widest effective absorption bandwidth(EABmax)of 4.56 GHz at 2.1 mm.Moreover,by adjusting the Ni source,the optimal EM wave absorption performance could be achieved.Results illustrated that the N3PC with the Ni proportion of 13.17%showed the RLm inas low as-51.1 dB at 2.4 mm and the EABmax was 5.12 GHz at 2.7 mm.It is worth noting that this work demonstrates the relevance of the composition and EM wave absorption performance of hybrid composites,which offers a feasible reference for the absorption mechanism of absorber. 展开更多
