Currently,precise ablation of tumors without damaging the surrounding normal tissue is still an urgent problem for clinical microwave therapy of liver ***,we synthesized Mn-doped Ti MOFs(Mn-Ti MOFs)nanosheets by in-situ doping method and applied them for microwave *** thermal imaging results indicate Mn-Ti MOFs can rapidly increase the temperature of normal saline,attributing to the porous structure improving microwave-induced ion collision ***,Mn-Ti MOFs show higher 1O2 output than Ti MOFs under 2 W of low-power microwave irradiation due to the narrower band-gap after Mn *** the same time,Mn endows the MOFs with a desirable T1 contrast of magnetic resonance imaging(r2/r1=2.315).Further,results on HepG2 tumor-bearing mice prove that microwave-triggered Mn-Ti MOFs nearly eradicate the tumors after 14 days of *** study offers a promising sensitizer for synergistic microwave thermal and microwave dynamic therapy of liver cancer.

The strong texture of Mg alloys can lead to strong tension–compression yield asymmetry and corrosion anisotropy,and this will consequently affect the effectiveness of hard tissue implants.A biomedical Mg–6Zn–0.5Zr alloy containing a large number of{1012}primary twins and{1012}–{1012}secondary twins is successfully prepared by cross *** dual twin structure not only removes the tension–compression yield asymmetry completely,but effectively reduces the corrosion anisotropy without compromise of corrosion *** difference between the largest corrosion rate and smallest one is~1.2 times compared to~1.6 times of the original *** is found that the reduced corrosion anisotropy is related to re-distribution of crystallographic orientations by twins.
