The development of multifunctional nanoparticles for diagnosis and therapy of cancer has been a focus of research in recent years. Owing to excellent properties of chemophotothermal therapy and tumor targeting accompanied by magnetic resonance （MR） or computed tomography （CT） imaging, mesoporous silica has been widely applied to tumor diagnosing carriers. However, previous research focused more on chemotherapy combined with photothermal therapeutic strategies but ignored intuitive assessment of tumors. In this work, we report a novel nanoprobe consisKng of hyaluronic-acid-modified gold nanorods@mSiO2.Mn@DOX （GNR@MMH@DOX） nanoparticles, which realize multifunctional integration of therapeutics and imaging. Au nanorods （GNRs） were synthesized without a seed precursor by a water bath method, then sequentially modified with mesoporous silica, doped with Mn2., and loaded with doxorubicin in a solution. In vitro and in vivo assays verified their great biocompatibility, good stability, and attractive specificity of targeting to receptor CD44, which is overexpressed on cancer cells. In addition, GNR@MMH nanoparticles proved to be a more distinguishable CT/MR imaging contrast compared to commercial contrast agents. The article demonstrates promising composition for CT/MR imaging and photothermal therapy of tumors, giving new insights into the diagnosis and therapy of different kinds of malignant tumors.

The granulation behavior of iron ores is essential for subsequent parameter optimization and efficient granulation, especially under changing material conditions. In this study, the effects of surface properties and particle size were analyzed using a laboratory granulation method; an estimation of the granulation of sintering blends was subsequently conducted for the base ores. Circularity and porosity were observed to negatively affect the granulation of iron ores, whereas wettability positively affected the granulation and was the most influential factor, indicating that wetting of iron ores is desirable during granulation. When iron ores with complex size distributions were granulated, the equivalent surface area was the main influencing factor for coarse particles larger than 1 mm and the ratio of adhering fines to intermediates was the main factor for fine particles smaller than 1 mm. By combining the granulation of coarse and fine particles with their proportioning, we proposed a calculation method for estimating the granulation ability of sintering blends. Good verification was demonstrated with the designed schemes. The results suggest that the developed method is effective for predicting the granulation of iron ore mixtures.

A homogeneous and compact super-aligned carbon nanotube(SACNT)-reinforced nickel-matrix composite was successfully prepared by electrodeposition. The mechanical properties of the laminar SACNT/Ni composites were substantially improved compared with those of pure nickel. With increasing content of SACNTs, the tensile strength of the composite increased and the elongation decreased because of the high-strength SACNTs bearing part of an applied load and the fine-grained strengthening mechanism. The nanohardness of the SACNT/Ni composites was improved from 3.92.GPa(pure nickel) to 4.62.GPa(Ni-4 vol%SACNTs). The uniform distribution of SACNTs in the composites and strong interfacial bonding between the SACNTs and the nickel matrix resulted in an improvement of the mechanical properties of the SACNT/Ni composites. The introduced SACNTs refined the nickel grains, increased the amount of crystal twins, and changed the preferred orientation of grain growth.

Coherent jets are widely used in electric are furnace （EAF） steelmaking to increase the oxygen utilization and chemical reaction rates. However, the influence of fuel gas combustion on jet behavior is not fully understood yet. The flow and combustion characteristics of a coherent jet were thus investigated at steelmaking temperature using Fluent software, and a detailed chemical kinetic reaction mecha- nism was used in the combustion reaction model. The axial velocity and total temperature of the supersonic jet were measured via hot state experiments. The simulation results were compared with the experimental data and the empirical jet model proposed by Ito and Muchi and good consistency was obtained. The research results indicated that the potential core length of the coherent jet can be prolonged by optimizing the combustion effect of the fuel gas. Besides, the behavior of the supersonic jet in the subsonic section was also investigated, as it is an important factor for controlling the position of the oxygen lance. The investigation indicated that the attenuation of the coherent jet is more notable than that of the conventional jet in the subsonic section.

Identification of fluorescent biomarkers with peptide ligand-directed receptors for diagnosis or theranostic of pancreatic ductal adenocarcinoma (PDAC) is still challenging. As potential prognostic/predictive bioimaging targets, both aminopeptidase N(APN, known as CD13) and Caveolin-1 are found as upregulation on the cell membrane surface of PDAC, in which APN is the principal receptor of the cyclic peptide cNGR (Asn-Gly-Arg, NGR) and Caveolin-1 can synergistically mediate endocytosis in this receptor-targeted process. Herein, we conjugate cNGR to dicyanomethylene-4H-pyran (DCM) chromophore to develop a synergistic-targeted near-infrared (NIR) fluorescent probe DCM-cNGR with strongly intrinsic NIR fluorescence, stable optical performance, low cytotoxicity, and rapid accumulation in PANC-1 cells with the synergistic overexpressed APN receptor-targeted and Caveolin-1-mediated endocytosis. As demonstrated, DCM-cNGR can realize noninvasive NIR imaging for targeting PANC-1 tumor in vivo after intravenous injection into PANC-1 xenograft tumor of nude mice, making a great promise to improve the precision diagnosis and therapy of pancreatic cancer with real time tracing and bioimaging of PDAC in vitro and in vivo.
