Technion researchers answer this question and pave new paths for applications in communication, imaging and quantum computing
New structures of carbon rings raise doubts about the current accepted definition of the concept of aromaticity
The development is a spin laser from a single atomic layer - a development by Prof. Erez Hasman from the Faculty of Mechanical Engineering and Prof. Elad Koren from the Faculty of Materials Science and Engineering.
Two articles by University College London researchers have been published in Nature Communications and Physics Magazine in which the researchers offer an elegant way to reconcile the contradiction between the two theories, each of which affects on a different scale
Researchers have used a variety of methods in order to reveal the different polymorphs that can be prepared from a common crystalline material and the paths of conversion of one configuration to another depending on the temperature and the method of preparation
While Einstein's theory of relativity shows the relationship between time and speed. Theoretical ideas such as wormholes offer possible methods, but practical challenges and paradoxes, such as the "grandfather paradox", complicate the feasibility of time travel in practice
Prof. Ashkenazi from the chemistry department at Ben-Gurion University is engaged in a new field - chemistry of complex systems. The grant was given to him and an international research group of which he is a member
"The observations will be made possible through the control we have developed over the wave nature of free electrons," explains Prof. Kaminer
Metal-organic frameworks (MOF) can safely trap fluorine compounds within their pores at room temperature and release them when needed
Today, quantum dots, which are tiny nanoparticles whose size determines their properties, illuminate computer monitors and TV screens when these are based on QLED technology. In the field of medicine, quantum dots are currently used to map biological tissues
The 2023 Nobel Prize in Physics was awarded to three researchers: Pierre Agostini, Ferenc Krausz and Anne L'Huillier for "the development of their methods that produce extremely short attosecond pulses of light For the study of the dynamics of electrons inside the material"
"This is the first measurement ever made of the free fall of antimatter (antihydrogen) atoms that directly shows that they really fall down," explained Prof. Eli Sharid from the Physics Department at Ben-Gurion University of the Negev, the member of the ALPHA collaboration group
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
The quick color switch allows an immediate change of the emitted color. The discovery has implications for diverse technologies in which fast color adjustment is required, such as display screens, quantum communication and miniaturized light sources
Quantum effects in X-rays make it possible to improve the resolution of the scan and protect the health of subjects and doctors
Meet Dr. Ohad Klein, PhD graduate in the Department of Mathematics at the Faculty of Exact Sciences, postdoctoral student at the Hebrew University and working at a startup company as an algorithmist
The French biotech start-up company called 'Carbios' succeeded in developing an enzymatic process to recycle the plastic polyethylene terephthalate (Polyethylene terephthalate) back to its component monomers, from which the finished polymer can be produced again
The shrimp has a particularly bright white color on its back and limbs that are intended to attract fish, which it 'cleanses' of pests it feeds on. An in-depth examination of the white substance using special electron microscopes revealed that the substance consists of an incredibly thin layer of very dense nanospheres (spheres of very tiny diameter)
Prof. Adi Aryeh: "We are standing at the threshold of a new technological world, and with it comes a host of new opportunities alongside a host of problems we have not yet encountered."
Doctoral student Benia Gros from the Department of Physics, the President's Scholar, has so far published 15 articles and one book, and presented his works dealing with dependent physical networks, at 9 conferences
Prof. Yael Shadami from the Faculty of Physics at the Technion focuses on the study of elementary particles including electrons, quarks, photons and gluons, and the interactions, or forces, that act between them. It tries to discover more elementary particles and interactions, beyond those described in the "standard model" of particle physics
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
On May 10, three lectures in the field of quantum will be delivered to the general public, zoomed and free of charge. The event is being held in honor of World Quantum Day under the auspices of the Center for Quantum Information at the Hebrew University. No need to register in advance.
In an article published in the magazine Nature Physics, a team of researchers from Britain, the USA, Germany and Australia demonstrated for the first time the two cracks experiment in the timeline. Instead of spatial dispersion on a screen, the temporal crack created a dispersion in the light spectrum, and from the combination of another crack an interference pattern similar to the spatial pattern from the classic experiment was created. The experiment opens a window for the construction of time-varying optical instruments in a reliable and stable manner.
It started with very strange experimental results, continued in a new physical theory about the behavior of photons, and in the future may improve our smartphone screens and allow faster data communication. faster data
