| 1 | Application of hopcalite catalyst for controlling carbon monoxide emission at cold-start emission conditions显示文摘Carbon monoxide(CO) is a poisonous gas particularly to all leaving being present in the atmosphere.An estimate has shown that the vehicular exhaust contributes the largest source of CO pollution in developed countries.Due to the exponentially increasing number of automobile vehicles on roads,CO concentrations have reached an alarming level in urban areas.To control this vehicular exhaust pollution,the end-of-pipe-technology using catalytic converters is recommended.The catalysts operating efficiently in a catalytic converter are a challenging class of materials for applications in cold start of engines to maintain indoor air quality.In the cold start period,the catalytic converter was entirely inactive,because the catalytic converter had not been warmed up.The cold start phase is also depending upon the characteristics of vehicles and property of catalysts.The increasing cost of noble metals with the increasing number of vehicles motivates the investigation of material concepts to reduce the precious metal content in automotive catalysts or to find a substitute for noble metals.Hopcalite(CuMnOx) catalyst could work very well at the low temperature;thus,it can overcome the problem of cold-start emissions if used in a catalytic converter.Further,low cost,easy availability and advanced synthesis methods with stabilizer,promoter,etc.,advocates for the use of hopcalite as an auto exhaust purification catalyst.Although there are numerous research articles present on this topic until now,no review has been presented for demanding this issue.So there is a space in this area,and it has been made an attempt to seal this hole and progress the future scope for hopcalite catalyst for purification of exhaust gases by this review. | Subhashish Dey Ganesh Chandra Dhal Devendra Mohan Ram Prasad | 2019 | Journal of Traffic and Transportation Engineering(English Edition)2019，6，5： | 3 |

| 5 | VARIABLE MESH FINITE DIFFERENCE METHOD FOR SELF-ADJOINT SINGULARLY PERTURBED TWO-POINT BOUNDARY VALUE PROBLEMS显示文摘A numerical method based on finite difference method with variable mesh is given forself-adjoint singularly perturbed two-point boundary value problems.To obtain parameter-uniformconvergence,a variable mesh is constructed,which is dense in the boundary layerregion and coarse in the outer region.The uniform convergence analysis of the method isdiscussed.The original problem is reduced to its normal form and the reduced problem issolved by finite difference method taking variable mesh.To support the efficiency of themethod,several numerical examples have been considered. | Mohan K.Kadalbajoo Devendra Kumar | 2010 | Journal of Computational Mathematics2010，28，5： | 0 |
| 6 | Effect of Surface Roughness on Laser Induced Nonlinear Optical Properties of Annealed ZnO Thin Films显示文摘Variation of nonlinear optical properties with surface roughness of ZnO thin films deposited on corning glass substrates at different annealing temperature(TA) was reported.The films were characterized by X-ray diffraction(XRD),UV-Vis-NIR transmission and single beam z-scan technique using second harmonics of Nd:YAG laser.Surface morphology of the samples was investigated by atomic force microscopy(AFM).Surface roughness was found minimum(8.4 nm) for ZnO sample annealed at 450 ℃.The nonlinear optical properties(NLO) were found to be dependent on surface roughness and the highest value of third order nonlinear susceptibility(χ~(3)=4.3×10~(-7) esu) was obtained for ZnO at TA 450 ℃. | Vinay Kumari Vinod Kumar Devendra Mohan Purnima B.P.Malik R.M.Mehra | 2012 | Journal of Materials Science & Technology2012，28，6： | 0 |
