In this paper,a silvered gradient nanostructured(GNS) layer was successfully fabricated on Ti6Al4V surface by means of surface ultrasonic rolling treatment (SURT)combined with silvering process.Surface characteristics,mechanical properties,corrosion resistance,antibacterial ability and cytotoxicity of GNS Ag/Ti6A14V were investi-gated in comparison with those of coarse-grained (CG) and GNS Ti6Al4V samples.Owing to the greatly enhanced dif-fusion kinetics of Ag in the GNS layer,surface silvering on GNS Ti6A14V was achieved at a relatively low temperature(500 ℃),and the release rate of Ag+ was substantially accelerated,which endowed GNS Ag/Ti6A14V with excel-lent antibacterial property.Moreover,improved wear and corrosion resistance of GNS Ag/Ti6Al4V can be achieved without cytotoxicity,indicating excellent bioadaptability.

Nano-silicon (nano-Si) and its composites have been regarded as the most promising negative electrode materials for producing the next-generation Li-ion batteries(LIBs),due to their ultrahigh theoretical capacity.How-ever,the commercial applications of na
Zn(CF3SO3)2 as an electrolyte has been widely used to improve the electrochemical performance for ZIBs due to that the bulky CF3SO3-can reduce the solvation effect of Zn2+ and promote the ionic diffusion.Herein,we found that Zn(CF3SO3)2 electrolyte can in

Acinetobacter baumannii and methicillin-resis-tant Staphylococcus aureus (MRSA) are two prevalent pathogens and have developed high resistant to most antibiotics.Therefore,it is a pressing need to develop a new method to inhibit the spread of drug-resista
Copper (Cu)-bearing stainless steel has testified its effectiveness to reduce the risk of bacterial infections.However,its antibacterial mechanism is still controversial.Therefore,three 430 ferritic stainless steels with different Cu contents are selected
Various solid state phase transformations exist in metastable β-type Ti alloys,which can be employed to optimize the mechanical properties.In this paper,syn-chrotron X-ray diffraction (SXRD) experiments were car-ried out to study the phase transformations
