In this study, using the 15N labeling method, it was found that nano-selenium could promote plant nitrogen...
Shift 1 - Students found the Physics and Mathematics sections moderately challenging. The chemistry section was easy. The paper covered topics from both classes 11 and 12, however, students found that the Physics section had more questions from class 12. JEE Main 2024 January 27- Students Reactio...
Despite the ubiquity of such interactions in biological systems and in the design of functional materials, the elusive nature of aromatic π interaction results in that they have been seldom used as a design element for promoting challenging chemical reactions. Described here is a well-engineered ...
and recovery time. In 2019, Tai [144] designed a gas sensing element based on a TiO2/Ti3C2Txbilayer film (Fig.7a). According to the results, when compared with the pure Ti3C2Txsensor, this TiO2/Ti3C2TXsensor exhibited a larger recognition value (1.63 times) with shorter response/recovery...
Within the promoters of target genes, CCA1 and LHY recognize two related cis-regulatory sequences known as the evening element (EE) and the CCA1-binding site (CBS) (Carre and Kay, 1995, Wang et al., 1997, Harmer et al., 2000). During the morning, CCA1 and LHY repress expression ...

118 elements, about 24 found in life, big 6 (H, O, C, N, S, P), most important 4 (H, O, C, N) what are isotopes? atoms of the same element with a different number of neutrons. how are isotopes identified? by their mass number. why do isotopes have the same chemical properti...
an atom of the same element with the same number of protons but a different number of neutrons. atomic mass the weighted average mass of an atom's isotopes sharing electrons in the outer shell what is a covalent bond? to make it stable through shared electrons. how and why does a covalen...
The key element in the success of population-based metabolomics over the last decade is the availability of the quadrupole tandem mass spectrometer. Contemporary instruments are very robust, fast and sensitive, although they have a lower mass resolution. An MS/MS unit can be coupled to GC or ...
