More effective, cheaper concrete manufactured with ash from olive residue biomass
Researchers at the University of Granada have produced self-compacting concrete with ash from boiler combustion of olive pruning residue pellets
The plasticity and cohesion of this type of concrete mean no compaction is needed when used in construction and, moreover, it has other advantages with respect to conventional concrete
University of Granada researchers have successfully manufactured self-compacting concrete using ash from the combustion of olive pruning residue pellets. Due to its plasticity and cohesion, this type of (...)

New System Patented for Building Inflatable Hydraulic Dams, Easy to Assemble and Disassemble
University of Granada researchers have designed a technique for assembling and dismantling a hydraulic dam in a few hours, with no specialized machinery and minimizing environmental harm
This dam, which is reusable, can be installed in sections of river that are difficult to reach and it can be easily transported to emergency zones or developing countries
University of Granada researchers have designed a technique for assembling and dismantling a hydraulic dam in a few hours, with (...)

The Snakelocks Anemone, a marine species prized in cooking, has been bred for the first time in captivity
Researchers from Granada have also artificially cultivated a salt marsh plant called Salicornia, an edible species which can be used to produce bio-fuels. These species are highly valued in gourmet cooking and are renowned for their exceptional nutritional properties. However, their harvesting has increasingly damaged marine ecosystems.
Researchers from Granada have managed to breed for the first time in captivity a marine animal known as the snakelocks anemone, (Anemonia sulcata), and have also begun breeding a (...)

A new material has been patented, using doped carbon, allowing fuels to be produced while, at the same time, reducing CO2 emissions
After more than 10 years' work, scientists at the University of Granada have a developed a carbon gel that enables CO2 to be turned into hydrocarbons by electro-catalytic transformation.
Researchers from the University of Granada (UGR) have developed a new material using doped carbon that allows low-cost energy to be produced and also reduces the amount of CO2 released into the atmosphere. The recently-patented material is a gel that enables the CO2 to be turned back (...)

A new computer simulator allows to design military strategies based on ants’ movements
A researcher of the University of Granada has designed a new system for the mobility of military troops within a battlefield based on the mechanisms used by ant colonies to move using a commercial videogame.This work, developed at the department of Computer Architecture and Technology of the UGR, has designed several algorithms that permit to look for the best route path (this is, to find the better route to satisfy certain criteria) within a particular (...)

New system of wastewater treatment could reduce the size of treatment plants by half
A group of researchers from the University of Granada (Universidad de Granada) have come up with a wastewater treatment system which has three clear advantages with respect to systems currently used: it is possible to obtain cheaper water of a higher quality, it considerably reduces the size of treatment plants (by more than half) and it minimizes the resulting mud production. José Manuel Poyatos Capilla, researcher from the Department of Civil Engineering of the University (...)

A new system will enable better prediction of the behaviour of old buildings subject to earthquakes
What happens if a big earthquake hits Spain? It is probable that a lot of buildings built before 1974 (the year in which the seismic regulation PDS-74 was passed, obligating all architects to prepare buildings against earthquakes) and even some buildings built after this year, will collapse. That is, they would not survive the earthquake or they would suffer such damage that they would have to be completely demolished. A study by Professor Amadeo Benavent (...)

Researchers from the UGR use a bacterium to obtain biopreservatives from food
The research group “Estudio de sustancias antagonistas producidas por microorganismos” (Antagonistic substances produced by microorganisms), part of the Microbiology Department of the University of Granada (Universidad de Granada), has succeeded in isolating enterocin AS-48, which could have a medium-term use as food biopreservative. This represents a significant advance, given that biopreservation is an innovative method in food-preservation systems based on the use of microorganisms or their metabolic products to inhibit or destroy undesirable microorganisms.Marina Sánchez (...)

A seminar of the UGR analyses concentrically braced frames for use in regions of high seismic risk
The Department of Structure Mechanics of the University of Granada organizes the Seminar Seismic performance of modern concentrically braced frames. The experts will deal with the seismic behaviour of concentrically braced frames for use in regions of high seismic risk in the United States. The Seminar is one of the activities programmes every year by seminar José Antonio García García, a meeting point to spread research news generated in the University of Granada as well (...)

A study of the UGR allows to improve techniques of cold-asphalting
Bitumen is used in traditional asphalting, a sub-product that remains after successive oil refining, and dry goods, stones that confer stiffness on roads. Bitumen acts as adhesive but, as it is a very viscous material, it has to be heated to be used. Since some years ago, big technological innovations have been introduced to carry out the cold process, using the so-called bituminous emulsions, heterogeneous systems composed of two stages or elements, insoluble of each (...)
