16 September 2016 Published: 04 October 2016 Yan-Zhen Zheng1,Yu Zhou2, Qin Liang1, Da-Fu Chen1, Rui Guo1 & Rong-Cai Lai1 In this work, hydrogen-bonding interactions between apigenin and water/ethanol were investigated from a theoretical perspective using quantum chemical calculat...
In this study, hydrogen-bonding interactions between myricetin—an abundant flavonoid in propolis—and ethanol or water were studied theoretically using density functional theory (DFT) methods. The molecular geometry and charge properties of the myricetin monomer were analyzed first. After careful ...
It was concluded that, by the presence of small amounts of organic acids, the water-ethanol hydrogen-bonding structure was strengthened, at the same time, the proton exchange between water and ethanol molecules was promoted in shochu, compared with the water-ethanol mixture. The NMR chemical ...
Phase equilibria of supercritical C02-ethanol-stearic acid ternary system and hydrogen bonding between ethanol and stearic acid Solubility of stearic acid in supercritical C02 with ethanol cosolvent was determined at 308.15 K in the pressure range from... Bing,Guan,Jie,... - 《Science in China》...
Yes, hydrogen bonding can occur between molecules of different substances. For example, water can form hydrogen bonds with other compounds, such as ethanol or ammonia, resulting in mixtures with unique physical properties. Additionally, hydrogen bonding can occur between molecules within the same substa...

As confinement increases, so too does the importance of interactions between the water molecules and the confining environment, with distinct consequences for the H-bonding structure14,15. Studies aiming to characterize the thermodynamic and dynamic properties of water in confinement have targeted various...

We study the dependence of viscosity of ethanol on shear rate using constant volume and constant pressure nonequilibrium molecular dynamics simulations, with the emphasis of the interrelationship between breaking, stability, and alignment of hydrogen bonds and shear thinning at high shear rates. We find...
