Research proposes more efficient and sustainable technology to transform industrial combustion

Burner or ignition systems are essential for the operation of industries such as pharmaceuticals, food and energy, as they facilitate the ignition of fuels to generate heat, energy or perform key processes. Their use in mining, manufacturing, construction and transportation, among others, ensures the continuity of operations. 

Development of a food additive based on maqui and patagua controls disease that causes mortality in salmon

Chile is one of the leaders in the world salmon industry, occupying second place in salmonid production, after Norway, and supplying 25% of the global supply. At the national level, this product is the largest exporter, after copper.

The sector faces several challenges, however, including the spread of diseases that threaten the stability and quality of production. One of the most common and dangerous is salmonid rickettsial septicemia (SRS), caused by the bacterium Piscirickettsia salmonis.

Innovative acoustic resonator of recycled plastic to reduce noise in work spaces

Audiological diseases due to continuous exposure to noise at work are among the main occupational pathologies in our country, according to data from the Superintendence of Social Security.

The WHO recommends a limit of 65 decibels to ensure good health and well-being of people, while Chilean regulations allow up to 85 decibels in eight-hour workdays, which is not always complied with.

Researchers develop a product to control aggressive phytopathogen that damages agricultural crops

Agricultural crops are permanently exposed to infections caused by dangerous phytopathogenic agents, which can seriously damage plants and even cause losses of vegetable crops. 

One of the most harmful phytopathogenic bacteria for agriculture is the species Pseudomonas syringae, which affects kiwifruit, cherry, plum, tomato and bean plantations, among others. As a result of this infection, there are considerable losses in production and harvests, implying millions of dollars in economic losses for the industry.

Prototype created to predict failures in ventilators begins field testing

With the aim of developing a mechanism that can predict faults in mining fans, a group of researchers from the University of Santiago de Chile, led by Dr. Sebastián Pérez from the Department of Mining Engineering (Dimin) Usach, are working on a Fondef R&D project, which has now begun field tests to prove its effectiveness in real operating conditions.

Usach Research focuses on recycled post-consumer PET for food packaging

PET is a fully recyclable plastic, which can be processed after use and converted into rPET (recycled PET) to manufacture new products. However, in Chile less than 15% of PET reaches recycling plants to be transformed into rPET, says a report by the Chilean Plastics Industry Association (Asipla). This is clearly illustrated by the low household recycling rate of plastic bottles, which barely reaches 7%.

Academic leads analysis of copper accumulation mechanism in algae

“This paper is very special for me because it represents the end of a stage of my career as a scientist,” said Dr. Alejandra Moenne Muñoz, an academic from the Faculty of Chemistry and Biology, after the results of the research she led clarified the mechanism of copper accumulation in the algae.

Usach researchers develop technology incorporating recycled material in yogurt containers

Currently, dairy packaging waste made of high impact polystyrene (PS) is not recycled to produce new containers for the same product, because this material has a particular chemical composition that causes its strong deterioration with recycling, hindering its performance for producing new resistant and safe containers for safe food preservation.

PS is a hard-to-replace petrochemical polymer due to its low cost, light weight and impact resistance which prevents container breakage.

First Made in Chile: Successful project to develop a charger for electric cars is successfully completed

Alongside industry leaders and representatives of key collaborators, the closing of the IDeA ID21I10412 project entitled “Design and development of a new ultra-fast multiprotocol charger with vehicle to grid capability for light and medium electric vehicles” was held on March 26. The initiative has consolidated an important step towards a more sustainable and efficient mobility future. It constitutes a breakthrough in the production and massification of electromobility in the country as the development of the first electric car charger made in Chile.

Project identifies eight positive impacts of providing bodies of water in the district of Recoleta

“Blue Spaces for Recoleta”, is the name of the research carried out by Dr. Lucio Cañete Arratia (project director), from the Faculty of Technology; Enrique San Juan Urrutia, Victor Herrera Gonzalez, both from the Faculty of Engineering; and Rodrigo Vidal Rojas, current rector and professor of the Faculty of Architecture and Built Environment. In this initiative, the academics of the Campus configured alternatives of free access water bodies (pools, fountains, tanks, etc.) present in the district of Recoleta.
