By showing that tiny particles injected into a liquid crystal medium adhere to existing mathematical theorems, physicists at the University of Colorado Boulder have opened the door for the creation of a host of new materials with properties that do not exist in nature.
Scientists investigated the electronic properties of nickel coated with graphene and achieved an astonishing result. They could show that the conduction electrons of the graphene behave rather as light than as particles.
Mathematics explains the observed 'beautiful and complex patterns revealed' in three-dimensional liquid crystal experiments, expected to lead to creation of new materials that can be actively controlled.
Tufts University School of Engineering researchers have developed a novel method for fabricating collagen structures that maintains the collagen's natural strength and fiber structure, making it useful for a number of biomedical applications.
The first meeting of United Nations Industrial Development Organization International Center on Nanotechnology (UNIDO ICN) was held in Tehran on December 12-13 titled 'The First Meeting for the Applications of Nanotechnology in Water and Wastewater Industry: Challenges and Opportunities'.
Scientists have developed a new method to determine the molecular orientation and clustering in thin films containing one of the most popular small molecules for organic solar cells, namely copper phthalocyanine (CuPc).
Researchers found that the precise location of the donor atom in the surface determined whether a positive or negative charge was induced in the surface, which was contrary to expectation because donors in bulk silicon are either neutral or positively charged, depending on sample temperature.
The major advance here is that we were able to make biodegradable nanoparticles that can rapidly penetrate thick and sticky mucus secretions, and that these particles can transport a wide range of therapeutic molecules.
Presently, finding biomimetic materials (the structure and function of biological systems), which are similar to bone in terms of strength, flexibility and density, is an ongoing concern for medical scientists. The hope is that it might be possible supplement metal alloy implants using such materials.
In a forced game of molecular tug-of war, some strings of atoms can act like a lever, accelerating reactions 1000 times faster than other molecules. The discovery suggests that scientists could use these molecular levers to drive chemical and mechanical reactivity among atoms and ultimately engineer more efficient materials.
