To solve the volume expansion and poor electrical conductivity of germanium-based anode materials,Ge/rGO/CNTs nanocomposites with three-dimensional network structure are fabricated through the dispersion of polyethylene-polypropylene glycol(F127)and reduction of *** interesting phenomenon is discovered that F127 can break GeO_(2)polycrystalline microparticles into 100 nm nanoparticles by only physical interaction,which promotes the uniform dispersion of GeO_(2)in a carbon network structure composed of graphene(rGO)and carbon nanotubes(CNTs).As evaluated as anode material of Lithium-ion batteries,Ge/rGO/CNTs nanocomposites exhibit excellent lithium storage *** initial specific capacity is high to 1549.7 mAh/g at 0.2 A/g,and the reversible capacity still retains972.4 mAh/g after 100 *** improved lithium storage performance is attributed to that Ge nanoparticles can effectively slow down the volume expansion during charge and discharge processes,and threedimensional carbon networks can improve electrical conductivity and accelerate lithium-ion transfer of anode materials.

Background:Hepatectomy is the preferred treatment for solitary hepatocellular carcinoma(HCC)without macrovascular invasion and distant metastasis,but long-term survival remains unsatisfactory in certain *** sought to identify whether the grading severity of microscopic vascular invasion(MVI)was associated with recurrence and survival among patients with solitary ***:Consecutive patients who underwent hepatectomy for solitary HCC were identified from a multicenter prospectively-collected *** were categorized into three groups according to the MVI grading system proposed by the Liver Cancer Pathology Group of China:M0(no MVI),M1(1-5 sites of MVI occurring≤1.0 cm away from the tumor),and M2(>5 sites occurring≤1.0 cm or any site occurring>1 cm away from the tumor).Recurrence-free survival(RFS)and overall survival(OS)were compared among the ***:Among 227 patients,97(42.7%),83(36.6%),and 47(20.7%)patients had M0,M1,and M2,*** RFS rates among patients with M0,M1,and M2 were 38.3,35.1,11.6 months,respectively,while OS rates were 66.8,62.3,30.6 months,respectively(both P<0.001).Multivariate Cox-regression analyses demonstrated that both M1 and M2 were independent risk factors for RFS(hazard ratio 1.20,95%CI:1.03-1.89,P=0.040;and hazard ratio 1.67,95%CI:1.06-2.64,P=0.027)and OS(hazard ratio 1.28,95%CI:1.05-2.07,P=0.035;and hazard ratio 1.97,95%CI:1.15-3.38,P=0.013).Conclusions:Grading severity of MVI was independently associated with RFS and OS after hepatectomy for solitary *** surveillance for recurrence and potentially adjuvant therapy may be considered for patients with MVI,especially individuals with more severe MVI grading(M2).

Grain-boundary（GB） structures are commonly imaged as discrete atomic columns, yet the chemical modifications are gradual and extend into the adjacent lattices, notably the space charge, hence the two-dimensional defects may also be treated as continuum changes to extended interfacial structure. This review presents a spatially-resolved analysis by electron energy-loss spectroscopy of the GB chemical structures in a series of SrTiO3 bicrystals and a ceramic, using analytical electron microscopy of the pre-Cs-correction era. It has identified and separated a transient layer at the model Σ5 grain-boundaries（GBs） with characteristic chemical bonding, extending the continuum interfacial approach to redefine the GB chemical structure. This GB layer has evolved under segregation of iron dopant, starting from subtle changes in local bonds until a clear transition into a distinctive GB chemistry with substantially increased titanium concentration confined within the GB layer in 3-unit cells, heavily strained, and with less strontium. Similar segregated GB layer turns into a titania-based amorphous film in SrTiO3 ceramic, hence reaching a more stable chemical structure in equilibrium with the intergranular Ti2O3 glass also. Space charge was not found by acceptor doping in both the strained Σ5 and amorphous GBs in SrTiO3 owing to the native transient nature of the GB layer that facilitates the transitions induced by Fe segregation into novel chemical structures subject to local and global equilibria. These GB transitions may add a new dimension into the structure–property relationship of the electronic materials.

To evaluate the effectiveness of weapon systems, the advantages and disadvantages of grey relational analysis and TOPSIS for multiattribute decision-making is pointed out, and an effectiveness evaluation model of weapon systems by combining grey relational analysis and TOPSIS is proposed. The model aggregates the grey relational grade and the distance to a new integrated closeness and reflects not only the trend but also the situation of the alternative. The example illuminates that the model is effective for the effectiveness evaluation of weapon systems.
