the compound we call water is created by combining the elements hydrogen and oxygen. One molecule of water is always made up of two hydrogen atoms and one oxygen atom. This is why water is referred to as H₂O in science. Water is created when elements chemically...

PROBLEM TO BE SOLVED: To provide an organic electroluminescent element using a compound exhibiting exciplex emission in a single molecule.FU YUSHIN夫 勇進FUJIMOTO DAIJIRO藤本 大二郎KIDO JUNJI城戸 淳二TAKEDA TAKASHI武田 孝
and p-shells can hold 6 electrons. Atoms are most energetically stable when the outer electron shell is full; therefore it is sometimes stabilizing for an electron to be lost producing a positive ion or for an electron to be gained
A light-emitting element having high emission efficiency is provided. A light-emitting element having a low driving voltage is provided. A novel compound which can be used for a tra
(GSH) is a versatile molecule capable of protecting cells against oxidants and toxicxenobiotics. However, it also plays key roles in multiple metabolic pathways, such as the synthesis of certainleukotrienes, proteins, and DNA precursors as well as the activation of enzymes, the regulation of ...
Lastly, another interactor which has the potential to disrupt NR interaction with HREs includesmall moleculepolyamidesdesigned to compete with NRs for binding to HREs[41,42]. Polyamides affect the DNA-dependent pathway selectively by interfering with the protein-DNA interface. Theseoligomerscan occur...
The luminescent dopant is a fluorescent or phosphorescent compound, which receives excitation energy from the host molecule and is excited and quenched to emit light. The assist dopant plays a role in complementing the carrier transport properties of the host material and accelerating the injection ...
atom系一种element入面最细而且不能分割的部份,而Ion是由于atom/molecule得到或者失去electron时而令atom/molecule中的正负电荷失衡,得到净正或负电荷,咁ion都系element入面最细而且不能分割的部份?polyatomic ion系多过一个 atom 的 ion,咁他算不算系compound?
Due to the difficulty to describe the oxygen molecule with high-spin ground state, the free energy of the O2 molecule was derived according to: $${{G}}_{{\mathrm{O}}^{2}}\left( {\mathrm{g}} \right) = 2G_{{\mathrm{H}_{2}{\mathrm{O}}}\left( l \right) - 2G_{{\mathrm{...
