Van der Waals forces(范德瓦尔斯力)VAN DER WAALS FORCES INTERMOLECULAR BONDING What are intermolecular attractions?Intermolecular versus intramolecular bonds Intermolecular attractions are attractions between one molecule and a neighbouring molecule. The forces of attraction which hold an individual molecule ...
The meaning of VAN DER WAALS FORCES is the relatively weak attractive forces that act on neutral atoms and molecules and that arise because of the electric polarization induced in each of the particles by the presence of other particles.

3.2.1Van der Waals Van der Waals forcesare well known to function as the primary interparticulate interaction in dry powder beds prepared by ordered mixing (Dickhoff, 2006). Specifically, small particles in the range intended for pulmonary delivery (<5 µm) exhibit increasedvan der Waals in...
The van der Waals interaction energy has been computed for a large number of silver and water particle pairs in the range of 1 to 15 nm radius by first calculating the exact, retarded Hamaker factor for semi-infinite bodies and then applying a geometric correction for sphericity. The ...
范德华力 (Van der Waals force) 范德瓦耳斯力(Van der Waals force),又称范氏引力或范德华力或凡得瓦力。在化学中,通常指分子之间的作用力。根据荷兰物理学家约翰尼斯·迪德里克·范·德·瓦尔斯命名。范德瓦耳斯力是一种电性引力,它比化学键弱得多。其中分子的大小和范德瓦耳斯力的大小成正比。 一个原子周...

Van der Waals forces are the weak forces that contribute tointermolecularbondingbetweenmolecules. Molecules inherently possess energy and their electrons are always in motion, so transient concentrations of electrons in one region or another lead electrically positive regions of a molecule to be attracted...
van′ der Waals'` forc`es (ˈvæn dər ˌwɑlz, ˌwɑls) n.pl. weakly attractive forces that act between neutral atoms or molecules. [1925–30; after J. Dutch. van derWaals(1837–1923), Dutch physicist] Random House Kernerman Webster's College Dictionary, © 2010 K Dict...
To this end, the non-bonding van der Waals (VDW) heterostructures, where the weak VDW force joins two distinct materials without forming direct chemical bonds, could offer a pathway to overcome such limitations.14,15Free of direct chemical bonding, many different materials may be readily combined...
