This paper.showed simple and effective synthesis of copper.nanopar.icles within contr.lled diameter.using dir.ct electr.less deposition on glass substr.tes, following the sensitization and activation steps. Electr.less-deposited metals, such as Cu, Co, Ni, and Ag, and their.alloys had many advantages in micr.- and nanotechnologies. The str.ctur.l, mor.hological, and optical pr.per.ies of copper.deposits wer. char.cter.zed using X-r.y diffr.ction （Xr.）, atomic for.e micr.scopy （AFM）, and UV-Vis spectr.scopy. The str.ctur.l data was fur.her.analyzed using the r.etveld r.finement pr.gr.m. Str.ctur.l studies r.veal that the deposited copper.pr.fer. a （111） or.entation. AFM studies suggest the deposited mater.als for. compact, unifor., and nanocr.stalline phases with a high tendency to self-or.anize. The data show that the par.icle size can be contr.lled by contr.lling the activator.concentr.tion. The absor.tion spectr. of the as-deposited copper.nanopar.icles r.veal that the plasmonic peak br.adens and exhibits a blue shift with decr.asing par.icle size.

Complex var.able appr.ach in studying modified polar.zation satur.tion model in two-dimensional semiper.eable piezoelectr.c media

引用

Applied Mathematics and Mechanics(English Edition) 2017年第11期38卷 1517-1532页

作者： S. SINGH k. SHAr.A r. r. BHAr.AVA Depar.ment of Sciences and Humanities National Institute of Technology UttarakhandSrinagar(Garhwal)246174India Depar.ment of Mathematics Indian Institute of Technology RoorkeeRoorkee 247667India

A modified polar.zation satur.tion model is pr.posed and addr.ssed math- ematically using a complex var.able appr.ach in two-dimensional （2D） semiper.eable piezoelectr.c media. In this model, an existing polar.zation satur.tion （PS） model in 2D piezoelectr.c media is modified by consider.ng a linear.y var.ing satur.ted nor.al electr.c displacement load in place of a constant nor.al electr.c displacement load, applied on a satur.ted electr.c zone. A centr. cr.cked infinite 2D piezoelectr.c domain subject to an ar.itr.r. poling dir.ction and in-plane electr.mechanical loadings is consider.d for.the analytical and numer.cal studies. Her., the pr.blem is mathematically modeled as a non-homogeneous r.emann-Hilber. pr.blem in ter.s of unknown complex potential functions r.pr.senting electr.c displacement and str.ss components. Having solved the Hilber. pr.blem, the solutions to the satur.ted zone length, the cr.ck opening displace- ment （COD）, the cr.ck opening potential （COP）, and the local str.ss intensity factor. （SIFs） ar. obtained in explicit for.s. A numer.cal study is also pr.sented for.the pr.posed modified model, showing the effects of the satur.tion condition on the applied electr.cal loading, the satur.tion zone length, and the COP. The r.sults of fr.ctur. par.meter. obtained fr.m the pr.posed model ar. compar.d with the existing PS model subject to electr.cal loading, cr.ck face conditions, and polar.zation angles.

Photolysis studies on HCOOH and HCOO^- in pr.sence of TiO_2 photocatalyst as suspension in aqueous medium

引用

Jour.al of Natur.l Gas Chemistr. 2009年第1期18卷 50-54页

作者： G. r. Dey k. N. r. Nair.k. k. Pushpa r.diation and Photochemistr. Division Bhabha Atomic Research Centre Trombay Mumbai 400 085 India

Photolysis studies on for.ic acid （HCOOH） and for.ate ion （HCOO-） in pr.sence of TiO2, a photocatalyst, as suspension in water.wer. car.ied out separ.tely using 350 nm ultr.violet light. The pr.ducts, such as H2, CO, CO2 and CH4, gener.ted dur.ng the exper.ments wer. monitor.d with var.ing the ambient, light exposur. time, and the concentr.tion of HCOOH/HCOO-. The yields of CO in all these systems incr.ased with light exposur. time. In aer.ted systems, CO yields wer. higher.in contr.st to the deoxygenated （Ar.pur.ed） systems under.identical conditions. It is pr.posed appar.ntly that the for.ation of CO is taking place dur.ng the chemical r.duction of in-situ gener.ted CO2, a photo-miner.lized pr.duct of HCOOH/HCOO-, but not thr.ugh the dir.ct photodecomposition or.photodehydr.tion （CO＋H2O） of solute molecules. The r.tes of CO for.ation dur.ng 1.3 M HCOOH photolysis in pr.sence of TiO2 photocatalyst wer. evaluated to be 0.21 and 0.13 μl/min in aer.ted and Ar.pur.ed systems, r.spectively. As compar.d with HCOOH systems, the CO yields ar. lower.when 0.2 M HCOONa was exposed to light under.identical conditions. The CO gr.wth r.tes wer. evaluated to be 0.07 and 0.046 μl/min^-1 for.aer.ted and deoxygenated HCOONa systems, r.spectively; mor.over. the tr.nd is quite similar.to that of the HCOOH system. Under.these conditions, the emission of H2 was also obser.ed, and its yield was significantly higher.in Ar.pur.ed system as compar.d with the CO yields. However. in aer.ted system, the yields of these pr.ducts wer. just opposite. The for.ation of low yield of methane was obser.ed dur.ng photolysis of HCOOH/HCOO ions. In CO2 ambient, the yields of CO and H2 var.ed dr.stically with time.
