During chemical reactions, the bonds that hold molecules together break apart and form new bonds, rearranging atoms into different substances. Each bond requires a distinct amount of energy to either break or form; without this energy, the reaction cannot take place, and the reactants remain as ...
Reports on a method of measuring the weak hydrogen bonds that hold molecules together which may help scientists design drugs, model the chemistry of the Earth's ozone layer, and better understand the functions of the body's proteins. Slit-jet supersonic expansion; Imp...
The bonds that hold chemical elements or atoms together in order to form a molecule are known as intramolecular bonds. They are generally stronger than the bonds between the molecules and they can be categorized into different types such as covalent, ionic, and metallic bonds....
柯林斯例句 The molecules in regular liquids are held together by relatively weak bonds. 常规液体里分子之间的键合力相对较弱。 柯林斯例句 The insurance company will take warehouse stocks or treasury bonds as surety. 该保险公司将接受仓库库存货物或长期国库券作为担保。 柯林斯例句 We must, somehow, find...
Catch bonds are also less susceptible to soluble inhibitors than slip bonds, since the small soluble molecules cannot apply a significant drag force, so that the bonds with inhibitors will be shorter lived than those with the surface. If FimH does form catch bonds, then understanding the ...

Molecules – a neutral group of atoms held together by covalent bonds Molecular compound – a cmpd whose simplest units are molecules Chemical formula – indicates relative # of atoms of each kind in a chemical compound by using atomic symbols & subscripts ...
A hydrogen bond is a type of intermolecular force of attraction that is a stronger version of the dipole-dipole interaction (also an intermolecular force of attraction). Chemicals with more hydrogen bonds usually have higher boiling points because these hydrogen ...
In the real world of matter and form, there are a number of different types of chemical bonds that keep things together so that they don't fly apart. Different substances among both the living and the non-living are defined in part by the type of chemical bonds within them that hold the...
optical nanoscopy tool that integrates a glass optical fiber with a silver nanowire condenser. The device is a high-efficiency round-trip light tunnel that squeezes visible light to the very tip of the condenser to interact with molecules locally and send back information that can decipher and vi...
