TL;DR: In this article, the vapor phase methylation of catechol with dimethyl carbonate to selectively afford veratrole was obtained in a 97% yield at 583 K.
Abstract: Alumina loaded with potassium nitrate has a very high catalytic activity for the vapor-phase methylation of catechol with dimethyl carbonate to selectively afford veratrole. Thus, veratrole was obtained in a 97% yield at 583 K. The reaction pathway includes both guaiacol and catechol carbonate as intermediates.

TL;DR: Isothermal calorimetric studies of crystal nucleation and growth processes in the aqueous LiCl-H{sub 2}O have been carried out in this paper, where the results obtained by using emulsion samples, which protect against heterogeneous nucleation artifacts, can be reproduced by using bulk samples.
Abstract: Isothermal calorimetric studies of crystal nucleation and growth processes in the aqueous LiCl-H{sub 2}O it is demonstrated that the results obtained by using emulsion samples, which protect against heterogeneous nucleation artifacts, can be reproduced by using bulk samples. For the Ca(NO{sub 3}){sub 2}-KNO{sub 3} system some interference from heterogeneous nucleation is observed, but results of character rather similar to those in LiCl-H{sub 2}O are obtained. These are refined by the use of two different two-step observation schedules which probe the relation between nucleation-dominated and growth-dominated regimes. The results make it possible to compare the crystallization kinetics in aqueous solutions and ionic melts and contrast them with molten fluoride systems of previous studies.

TL;DR: Differences between nitrate uptake in light and dark are explained by the influence of light on nitrate reduction and differences in leaf growth rate have been discussed in relation to root resistance and leaf water content.
Abstract: Using a special apparatus, the uptake of nitrate, potassium, water, and oxygen by a maize plant was recorded at short intervals. After cutting most of the roots, the regrowth of the root system was measured in relation to the increase in nitrate, potassium, and water uptake, oxygen consumption of the root system, and leaf growth rate. It has been suggested that when the root surface is not limiting nitrate reduction is the rate-limiting process for nitrate uptake. Differences between nitrate uptake in light and dark are explained by the influence of light on nitrate reduction. Differences in leaf growth rate have been discussed in relation to root resistance and leaf water content.
