Nanotechnological sensor monitors metal detachments from mechanical mining shovels in real time. The solution improves processes and the safety of workers. It also increases the useful life of mining equipment. A problem present in the crushing process is the grinding of metallic elements from the teeth of mechanical mining shovels. For this reason, Cedenna presented a new technological solution to detect the fall of these teeth, avoiding accidents and work stoppages.

In its latest edition, the Induambiente Magazine highlights the research carried out by researchers from the Center for Nanoscience and Nanotechnology (CEDENNA) and the Institute for Agricultural Research (INIA) to measure agrochemical residues in fresh fruits and vegetables, more quickly and at a lower cost than conventional laboratory techniques. With this, monitoring could be extended to small and medium-sized farmers, helping to deliver less contaminated agricultural products to the population.

Scientific frauds by Dr. Eugenio Vogel - El Mercurio

Submitted by carmenibarra on Mon, 01/23/2023 - 21:38

In a recent article in the New York Times, Dr. Elisabeth Bik has addressed the recurring theme of scientific fraud. In a highly documented way, and with graphic elements, it illustrates irregularities in some publications in its area (microbiology). It is certainly not a new problem, nor one peculiar to a single field. Only the motivations change somewhat and the ways of doing it are modernized. Complaints appear everywhere, including those in our country..

Column by Dr. Dr. Eugenio Vogel, Senior Associate Researcher at CEDENNA and Full Professor at the Universidad de La Frontera, in which he highlights that “what could become the first nuclear fusion reactor is being quietly built in the south of France , called ITER by its acronym in English (International Thermonuclear Experimental Reactor). Unlike nuclear fission reactors, ITER uses the remaining energy that results from joining two heavy hydrogen atoms (or deuterium) to form an inert Helium atom, releasing energy.

“After six years of investigation, a group of researchers from the Center for Nanoscience and Nanotechnology (CEDENNA), through their startup Sistrat, created a sensor that detects the detachment, in real time, of wear elements from mining shovel buckets. . A long-awaited solution to one of the main production problems in the mining sector, because it damages the primary crusher and delays operations, severely affecting productivity.

When SARS-CoV-2 began its spread around the world, scientists quickly detected that the virus' Spike protein (which gives it its peculiar shape of crowns around it) was its key to entering human cells to cause infection.

Since then, the focus for developing treatments and vaccines has been on this protein. However, a group of Chilean researchers from the Center for the Development of Nanoscience and Nanotechnology (Cedenna) found that there are other key proteins that deserve attention.

Nanotechnology to detect pesticides in fruits and vegetables

Submitted by carmenibarra on Thu, 06/23/2022 - 16:16

Fluorescent nanoparticles will help determine the concentration of pesticides in fruits and vegetables. This technique is complementary to chromatography, which is traditionally used to detect pesticides. In addition, it would provide benefits such as a lower cost per analysis, as well as greater agility in the delivery of results.
