Published: January 2016

AbstractThe applicability of a portable, commercially available surface velocity radar (SVR) for noncontact stream gauging was evaluated through a series of field‐scale experiments carried out in a variety of sites and deployment conditions. Comparisons with various concurrent techniques showed acceptable agreement with velocity profiles, with larger uncertainties close to the banks. In addition to discharge error sources shared with intrusive velocity‐area techniques, SVR discharge estimates are affected by flood‐induced changes in the bed profile and by the selection of a depth‐averaged to surface velocity ratio, or velocity coefficient (α). Cross‐sectional averaged velocity coefficients showed smaller fluctuations and closer agreement with theoretical values than those computed on individual verticals, especially in channels with high relative roughness. Our findings confirm that α = 0.85 is a valid default value, with a preferred site‐specific calibration to avoid underestimation of discharge in very smooth channels (relative roughness ∼ 0.001) and overestimation in very rough channels (relative roughness > 0.05). Theoretically derived and site‐calibrated values of α also give accurate SVR‐based discharge estimates (within 10%) for low and intermediate roughness flows (relative roughness 0.001 to 0.05). Moreover, discharge uncertainty does not exceed 10% even for a limited number of SVR positions along the cross section (particularly advantageous to gauge unsteady flood flows and very large floods), thereby extending the range of validity of rating curves.

PtCu alloy nanotube arrays supported on carbon fiber cloth as flexible anodes for direct methanol fuel cell
Authors: Wang An‐Liang , Zhang Chi , Zhou Wen , Tong Ye‐Xiang , Li Gao‐Ren 
Published: January 2016

SignificanceThe rapid development of flexible and portable electrochemical energy devices has promoted the demand for flexible and lightweight electrocatalysts. Here we report flexible high performance electrocatalysts based on PtCu alloy nanotube arrays on carbon fiber cloth (CFC) (PtCu ANTAs/CFC) for direct methanol fuel cell (DMFC). Compared with Pt NTAs/CFC and commercial Pt/C, the PtCu ANTAs/CFC electrocatalysts exhibit significantly improved electrocatalytic activity and durability. Furthermore, the PtCu ANTAs/CFC electrocatalysts show excellent flexibility and they can keep almost constant electrocatalytic performance under the different distorted states, such as normal, bending and twisting states. The improved performance of the flexible PtCu ANTAs/CFC electrocatalysts can be ascribed to unique ANTAs, synergistic effect between Pt and Cu, and porous structure of CFC. This work shows the significant progress of high‐performance Pt‐based flexible anodes for DMFCs. © 2016 American Institute of Chemical Engineers AIChE J, 62: 975–983, 2016
Heterogeneous Gold‐Catalyzed Cascade Hydrogen‐Transfer Strategy for Selective Synthesis of Quinazolinones in Water
Authors: Tang Lin , Zhao Xianghua , Zou Guodong , Zhou Yuqiang , Yang Xingkun 
Published: January 2016

AbstractEfficient and selective synthesis of quinazolinones from 2‐nitrobenzonitriles and benzylic alcohols catalyzed by TiO2‐supported gold nanoparticles (Au/TiO2) has been developed. Various transformations, such as dehydrogenative oxidation of C−O and C−N bonds, reduction of nitro groups, condensation of aldehydes with amines, hydration of cyano groups and cyclization, can be achieved in the tandem hydrogen‐transfer reaction. This protocol presents broad substrate scope, good tolerance to air and water, excellent recycling of the catalyst and does not require any additive, oxidant or reductant, which enables straightforward, practical and environmentally benign C−N and C−O bond formation.

Published: January 2016

AbstractDespite recent improvements in the therapy for osteosarcoma, 30–40% of osteosarcoma patients die of this disease, mainly due to its lung metastasis. We have previously reported that intravenous injection of miR‐143 significantly suppresses lung metastasis of human osteosarcoma cells (143B) in a mouse model. In this study, we examined the biological role and mechanism of miR‐143 in the metastasis of human osteosarcoma cells. We identified plasminogen activator inhibitor‐1 (PAI‐1) as a direct target gene of miR‐143. To determine the role of PAI‐1 in human osteosarcoma cells, siRNA was transfected into 143B cells for knockdown of PAI‐1 expression. An in vitro study showed that downregulation of PAI‐1 suppressed cell invasion activity, but not proliferation. Moreover, injection of PAI‐1 siRNA into a primary lesion in the osteosarcoma mouse model inhibited lung metastasis compared to control siRNA‐injected mice, without influencing the proliferative activity of the tumor cells. Subsequent examination using 143B cells revealed that knockdown of PAI‐1 expression resulted in downregulation of the expression and secretion of matrix metalloproteinase‐13 (MMP‐13), which is also a target gene of miR‐143 and a proteolytic enzyme that regulates tumor‐induced osteolysis. Immunohistochemical analysis using clinical samples showed that higher miR‐143 expressing cases showed poor expression of PAI‐1 in the primary tumor cells. All such cases belonged to the lung metastasis‐negative group. Moreover, the frequency of lung metastasis‐positive cases was significantly higher in PAI‐1 and MMP‐13 double‐positive cases than in PAI‐1 or MMP‐13 single‐positive or double‐negative cases (P < 0.05). These results indicated that PAI‐1, a target gene of miR‐143, regulates invasion and lung metastasis via enhancement of MMP‐13 expression and secretion in human osteosarcoma cells, suggesting that these molecules could be potential therapeutic target genes for preventing lung metastasis in osteosarcoma patients.
