The average adult is 55% to 75% water by weight the variation is due to gender, height, lean body and shape. It is used for maintaining body temperature, absorbing nutrients, eliminating wastes, 10 and many cellular processes including enzyme catalysis 11.
9 You can go without food for about a month however, going only three days without water can be fatal. 6 Indeed, water is virtually the most important nutrient for our health. 8 Obviously life would not exist without it. 6 Water in liquid state is the principle criteria for planetary habitability. 5 Its presence supports life, and its absence brings death. 4 Water is the life-giving fluid that is always at the heart of creation. 2 It is necessary for the functions of life 3 and for life to function. provide funds for scholarships, fellowships, faculty recruitment and chairs, research, buildings, laboratories, classrooms and dormitories, and more.Water is the universal solvent 1 it can exist as a solid, liquid or gas. Based in New York City, the ATS and its network of chapters across the U.S. Technion people, ideas and inventions make immeasurable contributions to the world including life-saving medicine, sustainable energy, computer science, water conservation and nanotechnology.Īmerican Technion Society (ATS) donors provide critical support for the Technion-more than $1.74 billion since its inception in 1940. The Technion-Israel Institute of Technology is a major source of the innovation and brainpower that drives the Israeli economy, and a key to Israel’s renown as the world’s “Start-Up Nation.” Its three Nobel Prize winners exemplify academic excellence.
The Technion team’s light trapping method could save 90% or more of rare elements like Tellurium and Indium, with no compromise in performance. The findings could also be used to reduce the amount of extremely rare elements that the solar panel industry uses to create the semiconductor material in their second-generation photovoltaic cells. This is in strong contrast to conventional photovoltaic cells, which provide power only when the sun is shining (and not at night or when it is cloudy). Rothschild, these cells could store solar energy for on demand use, 24 hours per day. The breakthrough could make possible the design of inexpensive solar cells that combine ultrathin iron oxide photoelectrodes with conventional photovoltaic cells based on silicon or other materials to produce electricity and hydrogen. Interference between forward- and backward-propagating waves enhances the light absorption close to the surface, and the photogenerated charge carriers are collected before they die off." “The light is trapped in quarter-wave or even deeper sub-wavelength films on mirror-like back reflector substrates. “Our light-trapping scheme overcomes this tradeoff, enabling efficient absorption in ultrathin films wherein the photogenerated charge carriers are collected efficiently,” says Prof. Researchers have struggled for years with the tradeoff between light absorption and the separation and collection of photogenerated charge carriers before they die out by recombination. But it also presents challenges, the greatest of which was finding a way to overcome its poor electrical transport properties. Iron oxide is a common semiconductor material, inexpensive to produce, stable in water, and – unlike other semiconductors such as silicon – can oxidize water without itself being oxidated, corroded, or decomposed.
This is the enabling key to achieving high efficiency and low cost. “We have found a way to trap light in ultrathin films of iron oxide that are 5,000 times thinner than typical office paper. Avner Rothschild, of the Department of Materials Science and Engineering. “Our approach is the first of its kind,” says lead researcher Associate Prof.
