Chemists and engineers have discovered a fascinating new way to take some of the atmospheric carbon dioxide that's causing the greenhouse effect and use it to make an advanced, high-value material for use in energy storage products.
Retinal degeneration is one of the most worrisome dangers in the aging process. Now, researchers have made an important technological breakthrough towards a prosthetic retina that could help alleviate conditions that result from problems with this vital part of the eye.
Chemists have fabricated novel rewritable paper, one that is based on the color switching property of commercial chemicals called redox dyes. The dye forms the imaging layer of the paper. Printing is achieved by using ultraviolet light to photobleach the dye, except the portions that constitute the text on the paper. The new rewritable paper can be erased and written on more than 20 times with no significant loss in contrast and resolution.
Physicists have developed a new algorithm that is capable of solving the Boltzmann equation for systems of self-propelled particles. The new method also reveals previously unknown patterns of collective motion in such systems.
nano-archimedes is a Technology Computer Aided Design tool for the simulation of various technology relevant situtations involving the dynamics of electrons such as the transport in nanometer scale semiconductor devices (nanodevices) and the dynamics of N-body problems in quantum chemistry.
New research shows that the majority of consumers will accept the presence of nanotechnology or genetic modification technology in foods - but only if the technology enhances the nutrition or improves the safety of the food.
In a step toward understanding the factors that influence how nanotubes form, researchers have succeeded in filming them when they are only a few atoms old. These nanotube 'baby pictures' give crucial insight into how they germinate and grow, potentially opening the way for scientists to create them en masse with just the properties that they want.
A team of scientists has revealed how certain harmful bacteria drill into our cells to kill them. Their study shows how bacterial 'nanodrills' assemble themselves on the outer surfaces of our cells, and includes the first movie of how they then punch holes in the cells' outer membranes.
Bisher haben Amyloid-Proteinkomplexe vor allem als mutmaßliche Alzheimer-Auslöser eher unliebsame Bekanntheit erlangt. Biochemiker und Molekularbiologen aus Ulm und Jena haben nun entdeckt, dass sich diese Komplexe aufgrund ihrer Molekülstruktur aber auch nützlich machen können.
Figuring out the necessary composition and internal structure to create the unusual properties of metamaterials is a challenge but new research, borrowing concepts from binary computing, presents a way of simplifying things.
