We only have to read the labels of many commercial products to find colorants among their components. They are natural or synthetic additives authorised by food security regulations and used to colour food and drinks in an artificial way. A research team of the universities of Granada, Jaén and Almería have devised a process to obtain a natural colorant from the micro-algae Porphyridium cruentum.High performanceMany marine algae are rich in proteins with fluorescent properties. They (...)
The universe will be a bit closer to Earth within a few months. World’s greatest telescope, the Great Telescope Canary Islands (Grantecan), is gathering momentum to “come to light” (this is, to be used for the first time to observe the firmament), and the Universidad de Granada is present in this big project. The professor of Astrophysics Eduardo Battaner has participated since 1999 in the Grantecan Monitoring Commission, one of the greatest works of Spanish (...)
Oxygen, an essential element for life, accounts for 21% of the air we breathe. However, certain works are carried out in conditions where levels can be lower with fatal consequences for persons. There fore it is, according to the scientists, a safety system, fruit of a collaboration agreement between the University of Granada and the Spanish Command for Training and Army Doctrine (MADOC), whose headquarter is in this city.In order to improve the features and (...)
One more year, the scientists of the Universidad de Granada will travel to the Antarctica to puzzle out the secrets of the ice continent. The expedition, composed of the researchers of the Andalusian Institute of Geophysics and Seismic Disaster Prevention Inmaculada Serrano Bermejo and Benito Martín Martínez, will set a course tomorrow Tuesday, 6th of December, for Deception Island, where they will analyse its volcanic evolution and supervise the level of seismic activity, in order (...)
Tensioactives world production (compounds exerting the wash function in detergents) amounted to two million tons in 2001, including soap. The expectations of future growth are from three to four per cent, an increase closely connected with the world demand of detergents, which is higher and higher. In parallel with this increase, concern is growing too, as far as these products must be ecological, non-toxic, cheap and, in addition, effective. A research team of the University (...)
The great interest always aroused by activated coal in industry, both for its characteristics and its many applications, has not kept out of the technological advances that improve the quality of the products. In this sense, a research group of the Department of Inorganic Chemistry of the University of Granada works on a project subsidized by the Spanish Ministry of Environmetal Issues to obtain activated coal from polymeric waste as raw materials.Activated coal is a (...)
A research team of the University of Granada has developed a new method of water purification which has aroused the interest of several and research centres such as the Swiss Institute for Environmental Science and Technology and the US company Carole Engineers. It is a system based on the simultaneous use of ozone and activated coal, highly effective and specialized on the treatment of water for human consumption and, besides, it is faster and more (...)
The volcanic inside of Deception Antarctic Island will soon stop being one of the best kept secrets of nature. A team of scientists headed by the professor of the University of Granada Jesús Ibáñez has travelled for the eleventh consecutive year to the ice continent to design at last the three-dimensional structure of the volcano and get to know how it.The team, which returned to Antarctica last February, has already enjoyed several campaigns during which (...)
Salt crystallization is one of the main problems of world heritage. Their effects are devastating to such an extent that the can even provoke the loss of sculptural, pictorial and ornamental material. However, despite the last achievements in the field of restoration, up to now they have failed to design effective measures to fight against this problem. In order to prevent the damage caused by sulphates, chlorides and nitrates in buildings and their progressive erosion (...)
A team of scientists of the University of Granada has developed a new analysis technique that will guarantee the restoration and preservation of the oldest manuscripts of the city, relegated up to now to the lowest position. The method, developed by researchers of the departments of Painting and Analytical Chemistry in collaboration with the Institute of Materials Sciences of Seville, and the archives of the Royal Chancellery of Granada, Provincial Historic Museum of Granada and (...)
