Israeli scientists from the Technion-Israel Institute of Technology and the Weizmann Institute of Science recently combined one group’s expertise in tissue engineering with the other’s expertise in the physics of complex systems to understand in detail how mechanical forces can direct the orientation of developing blood vessels.

Jun 01, 2008... Solar cells produce electricity just by lying in the sun; they use the energy of photons, the particles of sunlight, to directly generate an electric current, hence their scientific name, photovoltaics. Although photovoltaic technology is still considered too expensive for large-scale applications, it increasingly finds its way into “niche” markets in locations with no readily available connection to the electricity grid—such as satellites, boats, camps, or remote settlements. According to PV News, between 1995 and 2000 the world market for photovoltaics more than tripled, from 78 to 288 megawatts per year; and by 2020 it is expected to increase more than tenfold, to 4 gigawatts per year. Weizmann Institute scientists are exploring new methods and materials for making photovoltaics a viable energy source in small- and large-scale applications.

If you’re Jewish and observe kosher dietary restrictions, you likely have never looked into a shrimp’s eye.
However, if you have, you might have noticed that it gleams in low light. That is because the shrimp has a reflector underlying its retina (a “tapetum”) made up of tightly packed nanoparticles that allow the eye to collect more light underwater.
This was discovered by scientists from Ben-Gurion University of the Negev and the Weizmann Institute of Science in Rehovot, central Israel.

Cotton fibers modified to glow under ultraviolet light. (Filipe Natalio)
Seven or eight thousand years ago, humans figured out that the natural fibers cotton plants produce could be spun into strands and woven into fabric. During the Industrial Revolution and after, it became one of the world’s most valuable commodities—and helped drive the slave trade in the Americas and Europe.
Cotton is great. It's soft and light and durable enough. It’s pretty warm and dries pretty fast. But is that really all it can do for us? Filipe Natalio, a chemist at the Weizmann Institute of Science in Israel, thinks cotton can do better.

The fictive temperature, which pertains to the material’s structure, can dramatically affect the toughness of metallic glass. Above, notched samples of metallic glasses of different fictive temperatures (increasing from left to right) change from brittle to ductile, as indicated by the yellow-marked region ahead of the notch.
Addressing a centuries-old question, researchers have uncovered a key element to how glasses transition into very resilient states. This breakthrough could allow for more reliable ways to use glasses — metallic glasses in particular — in a wide range of applications.

Among Prof. David Milstein's various research projects, the one considered to be most important helped scientists understand the bonds between carbon and hydrogen.
Prof. David Milstein of the Weizmann Institute is the 5772 Israel Prize laureate for chemistry and physics, Education Minister Gideon Sa'ar announced Sunday.
Milstein won the prize for his innovative research that finds new ways to create compounds using materials containing metals. His studies have environmental ramifications because they can help develop cleaner industrial processes.

Remember the exploding Samsung Galaxy Note 7s that made headlines three years ago?
Well, it turns out smartphones aren’t the only machines whose lithium-ion batteries can explode when overloaded. E-cigarettes, airplanes and electric vehicles also blow up from overheated batteries.
“When you sit on an e-bike, right over the battery, you are sitting on energy that is equivalent to 1 kilo of gunpowder, and in electric cars it’s equivalent to 100 times that much,” points out Niles Fleischer, CEO of Israeli startup ALGOLiON.

Israeli researchers have discovered new entities created from interaction between matter and light particles, Weizmann Institute of Science (WIS) reported Wednesday.
The research, published in the journal Nature Communications, has several implications in developing quantum applications, fine control of chemical processes and designing new materials.
The difference between light and matter should be a clear and simple division, but there are situations in which the two become so closely connected that the situation becomes blurred.

This it is the story of a unique material – made of a single compound, it conducts electrons in different ways on its different surfaces and doesn't conduct at all in its middle. It is also the story of three research groups – two at the Weizmann Institute of Science and one in Germany, and the unique bond that has formed between them.
The material belongs to a group of materials discovered a decade and a half ago known as topological insulators. These materials are conducting on their surfaces and insulating in their inside “bulk.” But the two properties are inseparable: Cut the material, and the new surface will be conducting, the bulk will remain insulating.
Jul 20, 2020... REHOVOT, ISRAEL—July 20, 2020—Scientists searching for better diagnostic tests, drugs, or vaccines against a virus must begin by deciphering the structure of that virus. And when the virus in question is highly pathogenic, such research can be quite dangerous. Prof. Roy Bar-Ziv of the Weizmann Institute’s Department of Materials and Interfaces; staff scientist Dr. Shirley Shulman Daube; Dr. Ohad Vonshak, a former research student in the Bar-Ziv lab; and current research student Yiftach Divon have an original solution to this obstacle. They demonstrated the production of viral parts within artificial cells.
