Nanoparticles found to violate second law of thermodynamics
It may be a little late for April Fool’s, but some skepticism is nonetheless warranted when reading that researchers have shown nanoparticles to disobey a fundamental law of physics which dictates the...
Can Rain Clean The Atmosphere?
As a raindrop falls through the atmosphere, it can attract tens to hundreds of tiny aerosol particles to its surface before hitting the ground. The process by which droplets and aerosols attract is co...
Chemotherapeutic Coatings Enhance Tumor-Frying Nanoparticles
In a move akin to adding chemical weapons to a firebomb, researchers at Duke Univ. have devised a method for making a promising nanoscale cancer treatment even more deadly to tumors. The invention all...
Nanoparticles Target And Kill Cancer Stem Cells That Drive Tumor Growth
Many cancer patients survive treatment only to have a recurrence within a few years. Recurrences and tumor spreading are likely due to cancer stem cells that can be tough to kill with conventional can...
Nanoparticle-Coated Bacteria Can Deliver Cancer Vaccine
Marking an important step in the development of immunotherapy cancer treatment, scientists have demonstrated that nanoparticle-coated bacteria can effectively deliver an oral DNA vaccine that stimulat...
Penn Dental prof uses nanoparticles to fight tooth decay
Nanotechnology may sound futuristic, but it has already found its way into household products, from cosmetics to cleaning solutions. And with a little help from a School of Dental Medicine scientist, ...
Fighting cancer and Ebola with nanoparticles
In medicine, finding a substance that attacks cancerous tumors without destroying the healthy tissue around it has long been the Holy Grail. From targeted remedies such as monoclonal antibodies to sur...
​Nano-particles in Your Brain ... for Science!
In "I'm sure this will never be used for evil" news, a team of scientists at MIT announced yesterday that they developed a way to directly stimulate neurons through the use of magnetic nano-particles ...

Interface (chemistry)
An interface is a surface forming a common boundary among two different phases of matter, such as an insoluble solid and a liquid, two immiscible liquids, a liquid and an insoluble gas or a liquid and...
Adsorption
Adsorption is the adhesion of atoms, ions, or molecules from a gas, liquid, or dissolved solid to a surface. This process creates a film of the adsorbate on the surface of the adsorbent. This process ...

Colloid
A colloid is a substance in which microscopically dispersed insoluble particles are suspended throughout another substance. Sometimes the dispersed substance alone is called the colloid; the term coll...

Emulsion
An emulsion is a mixture of two or more liquids that are normally immiscible (unmixable or unblendable). Emulsions are part of a more general class of two-phase systems of matter called colloids. Alth...

Foam
A foam is a substance that is formed by trapping pockets of gas in a liquid or solid. A bath sponge and the head on a glass of beer are examples of foams. In most foams, the volume of gas is large, wi...

Surfactant
Surfactants are compounds that lower the surface tension (or interfacial tension) between two liquids or between a liquid and a solid. Surfactants may act as detergents, wetting agents, emulsifiers, f...

Self-assembled monolayer
Self-assembled monolayers (SAM) of organic molecules are molecular assemblies formed spontaneously on surfaces by adsorption and are organized into more or less large ordered domains. In some cases m...

Adparticle
An adparticle is an atom, molecule, or cluster of atoms or molecules that lies on a crystal surface. The term is used in surface chemistry. The word is a contraction of "adsorbed particle". An adpa...
Aggregation number
An aggregation number is a description of the number of molecules present in a micelle once the critical micelle concentration (cmc) has been reached.A typical experiment to determine the mean aggrega...
Rate of solution
Rate of solution is how quickly a solute dissolves in a solvent.Factors determining the rate of solution are:
Disjoining pressure
Disjoining pressure (symbol Πd), in surface chemistry, according to an IUPAC definition, arises from an attractive interaction between two surfaces. For two flat and parallel surfaces, the value of th...
