Grignard reagents react with the nitrone (152; R = R1 = H) and similar compounds to give the 4-hydroxy-5-phenyl derivative 〈77ACS(B)701〉. The carbonyl group at the 2-position in (236) can be aminated directly using methylamine but the reactivity at this position can be easily ...
in Amiard-Triquet et al. 2011). In the presentation of the mechanisms involved in the defense of organisms against stress, we have adopted a traditional presentation, with the description of biological responses to different classes of contaminants and we have underlined that these mechanisms are ...
Environmental solid waste bioremediation is a method of treating contaminated solid waste that involves changing ecological conditions to foster the growth of a broad spectrum of microorganisms and the destruction of the target contaminants. A wide range of microorganisms creates metabolites that may break...
FTPE is a typical organic fluorophore with a monoclinicC2symmetry; its atomic structure is shown in Fig.1a. In crystals, the FTPE molecules are arranged in a layered form along theb-axis. The molecular stacking of FTPE crystal is shown in Supplementary Fig.1. In each layer, the molecules...
β-glucosidases play a critical role among the enzymes in enzymatic cocktails designed for plant biomass deconstruction. By catalysing the breakdown of β-1, 4-glycosidic linkages, β-glucosidases produce free fermentable glucose and alleviate the inhibition of other cellulases by cellobiose during sacc...
Microbial functional groups that actively participate in element cycling also vary in response to salinity changes in lacustrine settings. As an example, the relative abundance of nitrogen fixation genes, coding an important pathway for aquatic ecosystem productivity, is often reduced with high salinity ...
The two versions of the system were assessed using new data, which is why the performance of Version 2.0 differs from that in the previous section. The production accuracy improvement approach helped further improve the forecasting system. Considering that this approach traces the planning relative ...
The pattern of autonomous walking acquisition significantly differs in females, in that 20% acquire this functional skill within the physiological time window while 80% of them achieve this step late (p = 0.017). The timing of both autonomous sitting and autonomous walking milestones appears to be...

98. This structure enables quantum dots to emit powerful fluorescence that differs in nature from organic dyes. Quantum dots can be tuned to emit at between 450 nm and 850 nm (i.e., from ultraviolet to near infrared) by changing the size or chemical composition of the nanoparticle. Th...
