Magnetic properties of a novel Pr Fe Ti phase

In a systematic study of the (Pr1−xTix)Fe5 alloy series, the (Pr0.65Ti0.35)Fe5 alloy has been found to have a dominant phase with either the rhombohedral Th2Zn17 structure or the newly discovered Nd2(Fe,Ti)19 (S. J. Collocott, R. K. Day, J. B. Dunlop, and R. L. Davis, in Proceedings of the Seventh International Symposium on Magnetic Anisotropy and Coercivity in R‐T Alloys, Canberra, July 1992, p. 437) structure, depending on the annealing procedure. Powder‐x‐ray‐diffraction patterns and scanning electron microscopy show that the sample annealed at a temperature of 850 °C followed by 1000 °C has the 2:17 structure whereas annealing at 1000 °C directly leads to the new 2:19 structure. Energy‐dispersive x‐ray analysis yields Pr:Fe:Ti ratios of 10.7:86.2:3.1 for the Pr2(Fe,Ti)17 phase and 9.2:85.9:4.9 for the Pr2(Fe,Ti)19 phase. 57 Fe Mössbauer spectroscopy (at 295 K) gives values for the average 57 Fe hyperfine field of 15.7 T for the 2:17 phase and 17.5 T for the 2:19 phase, respectively

Tetrakis[(benzene-18-crown-6)potassium]bis[tris(thiocyanato)copper(I)]

The title complex, bis­(μ-benzene-18-crown-6)-3κ6 O:4κO;4κ6 O:3κO-bis­(benzene-18-crown-6)-1κ6 O,6κ6 O-tetra-μ-thiocyanato-1:2κ2 S:N;2:3κ2 N:S;4:5κ2 S:N;5:6κ2 N:S-dithio­cyanato-2κN,5κN-2,5-dicopper(I)-1,3,4,6-tetra­potassium(I), [K4Cu2(NCS)6(C16H24O6)4] or {[K(C16H24O6)]4[Cu(NCS)3]2}, consists of four [K(benzene-18-crown-6)]+ cations and two [Cu(NCS)3]2− anions, forming a dimeric structure with site symmetry . In each [Cu(NCS)3]2− anion, the CuI atom is coordinated by three N atoms of thio­cyanate ligands in a trigonal–planar coordination geometry. Each [Cu(NCS)3]2− anion bridges two [K(benzene-18-crown-6)]+ cations, with K—S distances of 3.317 (3) and 3.198 (3) Å, and two [K(benzene-18-crown-6)]+ cations are linked across a crystallographic centre of inversion, with K—O distances of 2.903 (5) Å

Effect of a poloxamer 407-based thermosensitive gel on minimization of thermal injury to diaphragm during microwave ablation of the liver.

AIM: To assess the insulating effect of a poloxamer 407 (P407)-based gel during microwave ablation of liver adjacent to the diaphragm. METHODS: We prepared serial dilutions of P407, and 22.5% (w/w) concentration was identified as suitable for ablation procedures. Subsequently, microwave ablations were performed on the livers of 24 rabbits (gel, saline, control groups, n = 8 in each). The P407 solution and 0.9% normal saline were injected into the potential space between the diaphragm and liver in experimental groups. No barriers were applied to the controls. After microwave ablations, the frequency, size and degree of thermal injury were compared histologically among the three groups. Subsequently, another 8 rabbits were injected with the P407 solution and microwave ablation was performed. The levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), blood urea nitrogen (BUN) and creatinine (Cr) in serum were tested at 1 d before microwave ablation and 3 and 7 d after operation. RESULTS: In vivo ablation thermal injury to the adjacent diaphragm was evaluated in the control, saline and 22.5% P407 gel groups (P = 0.001-0.040). However, there was no significant difference in the volume of ablation zone among the three groups (P \u3e 0.05). Moreover, there were no statistical differences among the preoperative and postoperative gel groups according to the levels of ALT, AST, BUN and Cr in serum (all P \u3e 0.05). CONCLUSION: Twenty-two point five percent P407 gel could be a more effective choice during microwave ablation of hepatic tumors adjacent to the diaphragm. Further studies for clinical translation are warranted
