The oil-in-water microemulsion containing N-butyl maleimide(NBMI. M_1) and styrene(St, M_2) was prepared. The complexation properties of NBMI and St in microemulsion were investigated by means of 1H-NMR. With the participation of charge-transfer complex(CTC). four reactivity ratios and the relative reactivity of free monomers and CTC were obtained. The result was compared with that measured by Mayo-Lewis method.

Background： High-dose chemotherapy followed by autologous stem cell transplantation （ASCT） is a promising approach tbr lymphomas. This study aimed to evaluate the effect of ifosfamide, cisplatin or carboplatin, and etoposide （ICE）-based regimen as a mobilization regimen on relapsed, refractory, or high-risk aggressive lymphoma. Methods： From June 2001 to May 2013, patients with lymphomas who mobilized by ICE-based regimen for ASCT were analyzed in this retrospective study. The results of the autologous peripheral blood stem cells collection, toxicity, engraftment after ICE-based mobilization regimen were analyzed in this study. Furthermore, risk factors for overall survival （OS） and progression free survival （PFS） were evaluated by univariate analysis. Results： The stem cells were mobilized using ICE-based regimen plus rituximab or ICE-based regimen alone in 12 patients and 54 patients, respectively. The results of stem cell mobilization were excellent. Ninety-seven percentages of the patients had the stein cell collection of at least 2.0 ×10^6, CD34^＋ cells/kg and 68% had at least 5 × 10^6, CD34^＋ cells/kg. Fifty-eight percentage of the patients experienced Grade 4 neutropenia, 20% developed febrile neutropenia, and only 12% had Grade 4 thrombocytopenia. At a median follow-up of 63.8 months, the 5-year PFS and OS were 64.4% and 75.3%, respectively. Conclusion： ICE is a powerful regimen for stem cell mobilization in patients with lymphomas.

The metallogenic theory of polygenetic compound ore deposit is the important basis for location prediction of hidden ore deposits in diwa regions. It can play an important role in each step of prediction research, targeting procedure, acquiring information and integrating information. In this paper, the authors discusses how to construct geological concept by using of the metallogenic theory of polygenetic ore deposits for predicting targeting area, to arrange investigation and detection for getting enough useful information, and to analyze and integrate information for reaching a trustful prediction conclusion. According to these strategies, we conduct a successful prediction of location of hidden ore bodies in the outer of the Fenghuangshan copper mine, a principal producing mine in Tongling Cu Au district.

Zeolite nanosheets with a short b-axis thickness are highly desirable in lots of catalytic reactions due to their reduced diffusion resistance. Nevertheless, conventional synthesis methods usually require expensive structure-directing agents(SDAs), pricey raw materials, and eco-unfriendly fluorine-containing additives. Here, we contributed a cost-effective and fluoride-free synthesis method for synthesizing high-quality MFI zeolite nanosheets through a Silicalite-1(Sil-1) seed suspension and urea cooperative strategy, only with inexpensive colloidal silica as the Si source. Our approach was effective for synthesizing both Sil-1 and aluminum-containing ZSM-5 nanosheets. By optimizing key synthesis parameters,including seed aging time, seed quantity, and urea concentration, we achieved precise control over the crystal face aspect ratio and b-axis thickness. We also revealed a non-classical oriented nanosheet growth mechanism, where Sil-1 seeds induced the formation of quasi-ordered precursor particles, and the(010)crystal planes of these particles facilitated urea adsorption, thereby promoting c-axis-oriented *** obtained ZSM-5 nanosheets exhibited exceptional catalytic performance in the benzene alkylation with ethanol, maintaining stability for over 500 h, which is 5 times longer than traditional ZSM-5 catalysts. Furthermore, large-scale production of ZSM-5 nanosheets was successfully carried out in a 3 L highpressure autoclave, yielding samples consistent with those from laboratory-scale synthesis. This work marks a significant step forward in the sustainable and efficient production of MFI nanosheets using inexpensive and environmentally friendly raw materials, offering the broad applicability in catalysis.
