Effects of supplying K2O at 0, 12, 24 and 36 g m 2 soils on distribution of photosynthates (carbohydrates produced by photosynthesis) were studied in plants of Ipomoea batatas Lam (Beijing 553). Storage roots yield, photosynthate distribution, sucrose synthase and insoluble acid invertase activities, as well as abscisic acid content in storage roots were determined. The storage root yield firs...

the no removal over oxide sorbents (k2o/al2o3 , cao/al2o3 and bao/al2o3) at a loading of up to 25 wt.% was investigated using a synthetic diesel exhaust gas containing  1,000 ppm no, 1000 ppm iso-butane (i-c4h10), 8% o2 and n2 balance. the reactor was operated  at 250 oc to 450 oc for the activity study. no was effectively stored (removal efficiencies between 30-60 %) as nitrate under experimen...

CO2 reforming of methane (CRM) over unpromoted and potassium promoted Ni/Al2O3 catalysts was studied. The catalysts were prepared by impregnation method and characterized by X-ray diffraction (XRD), N2 adsorption (BET), temperature programmed reduction (TPR), temperature programmed oxidation (TPO) and scanning electron microscope (SEM) techniques. The obtained results showed that addition of K2...
