Two primary ways are the use of distilled water (both of domestic and industrial origin), and of fertilizers based out of biological mixtures. A study done by the Institute of Water and the Department of Microbiology at the University of Granada, directed by Dr. Maria del Mar Sánchez Peinado, stress the importance of controlling the contamination of our farm grounds. This is due to the increasing presence of linear alkyl benzene sulphonate, a chemical component whose active ingredient can be found in most detergents.
The research project, carried out by three professors, Clementina Pozo Llorente, Maria Belén Rodelas González, and Maria Victoria Martínez Toledo, was financed by the Ministry of Education. This study has proven to be an important advancement towards further understanding of agricultural soils as a receptor of these pollutant compounds, as well as the impact of such compounds on the microbial community, and its microbiotic role on agricultural soils with regards to LAS biodegradation processes. The field work of this study was conducted in the lowlands of Spain, researching LAS biotransformation capacity with regards to microbiota as well as its biotransformation kinetics.The most utilized
This research work goes deeply, from chemical, microbiological and molecular techniques, into the impact of LAS in the structure, function and composition of the microbial community in the soil ecosystem. Likewise, the scientists have analyzed the biodegradation capacity of this pollutant in fields with regards to the microbial community combining techniques corresponding to different knowledge areas, such as microbiology, analytical chemistry and microbiology. With regards to agricultural soils, “the use of biological mud as a fertilizer and the great demand for water due to agricultural needs are the main means ways that LAS reaches the fields”. A unique ecosystem, where biological interactions and biogeochemical processes, associated to organic material degradation and mineral elements transformation for plant nutrition are especially intense.
The scientists of the University of Granada warn about the negative effects of LAS “LAS could significantly alter the metabolic activity of soils, therefore affecting their fertility”.

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
