In this work, we develop a novel 1-(2-Pyridylazo)-2-naphthol (PAN)-based acidic sulfate copper electronicelectroplating process for compact, homogeneous and conformal copper thickening of throughhole (TH). The adsorption characteristics, electrochemical properties and the interaction mechanismsof three additives (PEG, SPS and PAN) are studied in detail. Scanning electron microscope (SEM) and opticalmicroscope (OM) reveal that PAN can make the copper coating in fine grains and high throwing powerof 90.35% in TH without an overhang phenomenon. Theoretical calculations illustrate that the bindingenergies between additive molecules and copper surface decrease in the order: PAN > SPS > PEG. Cyclic voltammetry experiments at rotating rates of 1200 and 200 r/min prove that PAN itself can accelerateand weakly suppress copper electrodeposition at the center and mouth of TH, respectively. PANbehaves respectively the synergistic and antagonistic effects with PEG at the mouth and center of TH,and the weakly synergistic effects with SPS both at the mouth and center of TH. The addition of PANto the virgin make-up solution (VMS) containing PEG and SPS causes decreasing the relative electriccharge (DQ) at high and low rotating rates from 18.52 ± 0.08% to 8.25 ± 0.05%, which satisfies the closercopper electronic electroplating rate at the center and mouth of TH. The effective and complicated synergisticeffects of the additives PEG, SPS and PAN can achieve compact, homogeneous and conformal copperthickening of TH.

Experimental investigation of the preferred Strouhal number used in self-resonating pulsed waterjet
Deng Li,Youping Chen,Yong Kang,Zu’an Wang,Xiaoliang Wang,Qi Fan,Miao Yuan 대한기계학회 2018 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.32 No.9
Self-resonating pulsed waterjet (SRPW) is superior to plain waterjet in many ways and is being employed in numerous applications. To further improve the performance of SRPW, the optimal value of the preferred Strouhal number (S d ), which is used to determine the chamber length of a self-resonating nozzle, was experimentally studied at inlet pressures of 10 MPa and 20 MPa. The axial pressure oscillation peak and amplitude were used to evaluate the performance of SRPW, in order to find the optimum S d value. Results show that S dvalue determines the self-resonance behavior of an organ-pipe nozzle and greatly affects the intensity of the axial pressure oscillation. Under the experimental conditions, the optimum S d values are 0.315 and 0.278 respectively, corresponding to inlet pressures of 10 MPa and 20 MPa. Compared with the default value of 0.3 obtained from air jet experiment, the optimum S d value at inlet pressure of 10 MPa is a little larger and oppositely a bit smaller at inlet pressure of 20 MPa. Thus, if the inlet pressure is not considered, S d value of 0.3 is reasonable for determining the chamber length of a self-resonating nozzle for generating effective SRPW.

Objectives: To determine the prevalence of HPV and cervical neoplasia among HIV-infected women in southwestern China. Methods: Cervical cytology, HPV detection by Hybrid Capture-$2^{TM}$ assay, and diagnostic colposcopy were followed by cervical biopsy if indicated. Logistic regression analysis was used to analyze associations between HPV co-infection and cervical intraepithelial neoplasia (CIN), and HIV-related clinical and laboratory parameters. Results: Colposcopic-histopathologically proven CIN2+ lesions were present in 7/83 (8.4%) HIV-infected women. Nearly half (41/83, 43%) were co-infected with carcinogenic HPV genotypes. HPV co-infection was higher in women with colposcopic-histopathologically proven CIN2+ lesions than women with <CIN1 after adjusting for age (OR: 8.3, 95% CI: 0.9, 73.4). Women with CD4+ cell counts less than 350 $cells/{\mu}L$ had higher CIN2+ prevalence after adjusting for current ART status and age (adjusted OR: 6.3, 95% CI: 1.1, 36.5). Conclusions: HIV/AIDS care and treatment programs should integrate effective cervical cancer prevention services to mitigate the risk of invasive cervical cancer among HIV-infected women in China.
