n, o, nac2 plants exhibited higher attractiveness to aphids than WT plants in circular-dish (n) or Y-tube olfactometer bioassays (o). Numerals shown inside each bar present number of choice-making aphids. p, q, nac2 plants smeared with MeSA containing lanolin exhibited similar attractiveness...
The concentrations in the systems were 5 and 15 wt% for THF, 100, 300, and 400 ppm for GO, and 0.2, 0.4, and 0.6 wt% for Al2O3. It is concluded that 15 wt% THF solutions decline the induction time, and promote the mole of consumed gas, rate of gas uptake, apparent rate ...
Effects of low-molecular- weight organic acids on sorption-desorption of phenanthrene in soils[J]. Soil Science Society of America Journal,2010,74 ( 1) : 51-59.Gao YZ, Ren LL, Ling WT, Kang FX, Zhu XZ, Sun BQ. Effects of low-molecular-weight organic acids on sorption-desorption of ...
A novolac resin having a 96°C Durran's softening point was prepared using a 0.75:1 mole ratio of formaldehyde to phenol. Formaldehyde was fed into phenol (containing 0.6 wt. % oxalic acid) at 100°C over approx. 1 hour period. This was reacted 1 hour and then the excess phenol and...
The catalyst which is present in an amount of 4-240 wt. % (based on formose solution) is a compound taken from the group consisting of nickel, cobalt and compounds thereof. The mixture of polyhydroxyl compounds made in accordance with the present invention is useful as a starting material ...
was etched by a hydrothermal process using oxalic acid and NH4F at different temperatures of 100–180 °C for 24 h (Figure 2C) [30]. The kinetic of this method depended on the acidity of the dissociated organic anion and its interaction with the dissociated F of the ionic liquid....
