Researchers have developed a new model that allows better control of self-assembly, the process through which molecules aggregate by themselves into larger clusters. This model could be used in the production of plastic solar cells, and is an interesting step in the long?term process of developing a synthetic cell.
The structural-mechanical property relationship at the atomic scale suggests that cortical bone performance is correlated to the feature, arrangement, movement, distortion, and fracture of hydroxyapatite nanocrystals.
Graphene emerges as a versatile new surface to assemble model cell membranes mimicking those in the human body, with potential for applications in sensors for understanding biological processes, disease detection and drug screening.
New York University chemists have discovered crystal growth complexities, which at first glance appeared to confound 50 years of theory and deepened the mystery of how organic crystals form. But, appearances can be deceiving.
Carnegie Mellon University's Center for Silicon System Implementation (CSSI) has received a $2.6 million grant from the National Science Foundation (NSF) to develop next-generation ultra-efficient silicon chips that could trigger a revolution in how chips are designed and operated.
The primary goal of the European project INFERNOS (Information, fluctuations, and energy control in small systems) is to realize experimentally Maxwell's Demon; in other words, to develop the electronic and biomolecular nanodevices that support this principle.
Omid Farokhzad's vision of medicine's future sounds a lot like science fiction. He sees medicine scaled down, with vanishingly small nanoparticles playing a big role, delivering drug doses measured in molecules directly to cancerous tumors.
To gauge whether suspects involved in accidents or routine traffic stops have been driving drunk, police officers pair field sobriety tests with breathalyzers, which signal the presence of alcohol in the breath. Most breathalyzers are expensive and unable to test for precise concentrations of alcohol. Offering a better solution, Italian researchers have developed a novel idea for an inexpensive, portable breathalyzer whose color would change from green to red with higher alcohol concentrations.
