  • One response
The applicability of the new technology is demonstrated in the contexts of local cell transplantation, drug transport for controlled local release over time and 3D bioprinting. The mechanical properties of the scaffolds can be adjusted according to the target tissue and the desired drug release rate

Two birds with one stone - turning carbon dioxide into carbon nanofibers

The idea of ​​capturing carbon dioxide or converting it to other substances in order to combat climate change is not new. However, simply storing carbon dioxide in a certain compound may lead to its leakage into the environment
Caption: Above, azobenzene is a molecule that can change its shape with light. An azobenzene molecule switches between two forms under the influence of light. In the lower figure: a molecular cage containing the molecules of the photosensitizer azobenzene. The new mechanism is based on a supramolecular approach in which the molecules of azobenzene and the photosensitizer are locked together in a molecular cage. The limited space accessible to the caged molecules allows only the E-form, but not the Z-form of azobenzene, so this molecule is pushed out of the cage. Credit: Jonathan R. Church

Azobenzenes are versatile compounds with many potential uses, such as advancing technology through the production of tiny machines, as well as creating light-activated drugs. These molecules can be found in two different forms called "E" and "Z" which can be exchanged between them through irradiation. However, under irradiation conditions both forms are in equilibrium, which prevents optimal utilization for different applications

Researchers demonstrated the benefits of a natural, non-radioactive dye by observing viruses at the nanometer level. The innovative substance is a structurally stable substance and is a natural molecule with a longer shelf life than the radioactive substance most often used for this purpose, uranyl acetate
"Scale of Polarizations"

electronic skips

Researchers have built surfaces from layers of atoms that slide over each other, thus causing the electrons inside to skip. In the future, they hope that it will be possible to develop advanced information technologies based on them

An observation in Bar-Ilan yielded surprising results in the field of material conductivity

  • No comments
An experiment conducted in the physics department at Bar-Ilan, in the research group of Prof. Bina Kalisky, using a unique sensor developed by the researchers, documented a phenomenon that breaks conventions in the field of the transition of a material from a conductor to an insulator. The observation of the sensitive instrument showed that if you look very closely, you discover that a law that is considered universal ceases to exist
