Not only in information technology: restart also works in chemical simulations

The innovative way of expediting chemical simulations: resetting them

15-Feb-2024 - A new study from Tel Aviv University discovered that a known practice in information technology can also be applied to chemistry. Researchers found that to enhance the sampling in chemical simulations, all you need to do is stop and restart. The research was led by Ph.D. student Ofir Blumer, in ...

Researchers turned transparent calcite into artificial gold

Breakthrough in metamaterials: New material can serve as a platform for innovative cancer treatments

15-Jun-2021 - For the first time in the world, researchers at Tel Aviv University developed an innovative nanotechnology that transforms a transparent calcite nanoparticle into a sparkling gold-like particle. In other words, they turned the transparent particle into a particle that is visible despite its very ...

Induced flaws in metamaterials can produce useful textures and behavior

Discovery advances the understanding of structural defects and their topological properties

10-Feb-2020 - While a piece of paper is usually flat and floppy, the same piece of paper crumpled into a wad is stiff and round. This demonstrates that scrunching changes the texture and behavior of precisely the same material -- paper. A new Tel Aviv University study shows how induced defects in metamaterials ...

Massive particles test standard quantum theory

First explicit bounds from interference experiments with matter waves

18-Aug-2017 - In quantum mechanics particles can behave as waves and take many paths through an experiment, even when a classical marble could only take one of them at any time. However, it requires only combinations of pairs of paths, rather than three or more, to determine the probability for a particle to ...

Nano-sized chip "sniffs out" explosives far better than trained dogs

Tel Aviv University researcher's groundbreaking sensor detects miniscule concentrations of hazardous materials in the air

01-Aug-2014 - Security forces worldwide rely on sophisticated equipment, trained personnel, and detection dogs to safeguard airports and other public areas against terrorist attacks. A new electronic chip with nano-sized chemical sensors is about to make their job much easier. The groundbreaking ...

Simple synthesis of heavy oxygen-labelled alcohols

27-May-2013 - Research reports a novel and extremely simple method for synthesising 18O-labelled alcohols using commercial boronic acids and a reagent prepared from elemental fluorine. Alcohols labelled with 18O are very valuable as biological probes for a variety of studies which are often limited by the ...

Individual protein complex generates electric current

Solar cell consisting of a single molecule

05-Oct-2012 - An team of scientists, led by Joachim Reichert, Johannes Barth, and Alexander Holleitner (Technische Universitaet Muenchen, Clusters of Excellence MAP and NIM), and Itai Carmeli (Tel Aviv University) developed a method to measure photocurrents of a single functionalized photosynthetic protein ...

Controlling superconductors with light

Tel Aviv University researcher discovers that a ray of light could lead to the next generation of superconductors

29-Aug-2012 - A superconductor, which can move electrical energy with no wasteful resistance, is the holy grail of cost-effective, efficient, and "green" power production. Unlike traditional conductors such as copper or silver, which waste power resources and lose energy when they heat up, an ideal ...

Out-sniffing bomb-sniffing dogs

Tel Aviv University researcher leads development of swift, small, highly reliable sensor to detect explosives

16-Nov-2010 - Dogs have long been called man's best bomb detector –– until now. A Tel Aviv University scientist leads a research team that has developed a powerful electronic sensor to detect multiple kinds of explosives –– including those used in the recent Yemeni bomb threat. Based on nanotechnology ...

A nemesis for oil spills

Proven Tel Aviv University bacterial technology can clean up the oil that BP's cleaning crew leaves behind

10-Aug-2010 - It's taken millions of dollars to cap it, and it could take billions more to clean it up. BP's oil spill in the Gulf of Mexico is acknowledged the environmental catastrophe of the century. But Tel Aviv University has a solution that may help "bioremediate" the remaining problems. Prof. Eugene ...
