ZnS and ZnS:3.125%Ce^(3+)(ZSC)quantum dots(QDs)were synthesized by a low-temperature solid-phase *** crystal structure,photoluminescence(PL)properties of ZSC QDs,and their effects on the growth and kojic acid production of Aspergillus oryzae(***)were *** is found that both QDs have a cubic blend structure with the average particle size ranging of 2.75-6.14 ***^(3+)doping not only increases the band gap of ZnS QDs from 3.43 to 3.48 eV,but also increases the PL intensity by about 2.23 times,which is due to the fact that the electron carrier concentration is improved,and then the rate of radiative recombination is *** integral emission intensity,biomass,extracellular proteins yield,and kojic acid production of *** cultured with ZSC(ZnS)QDs are about 4.31(3.23),1.61(1.20),1.12(1.09),and 2.99(1.68)times higher than that of medium without QDs,respectively.

Two-dimensional combustion flame front and temperature profiles of ultra low-calorific gases in porous combustor are investigated *** characteristics of the flame front,high temperature profiles under certain operating parameters,and the flame propagation process are *** effects of operating parameters,such as equivalence ratio,superficial velocity of gas and the wall heat loss,on the flame front and high-temperature zone are *** results show that the shape of the flame front is gradually changed in the propagation process of the ***,this process results in the variation of the high temperature *** the equivalence ratio increases,the inclination of the flame front near the wall decreases gradually,while the combustion flame propagates upstream *** shape of the flame front gradually changes from the trapezoid to the straight-line distribution with downward inclination on both *** effect of gas velocity on the shape and position of flame front is contrary to that of the equivalence *** the other hand,the wall-heat loss can lead to the inclination of the flame front near the combustor wall,while the effect on the position of flame is less.
