Study Shows the Potential of Carbon Nanotubes to Cool Electronic Circuits
Publicado em 26 de abril de 2019
The use of solid-state refrigerators to cool appliances and electronic devices is a possible technological application for a theoretical study conducted at the University of Campinas (UNICAMP) in São Paulo State, Brazil.
Although this application is not considered in the study, which was based on computer simulations, such applications are on the horizon and could be an efficient and environmentally friendly alternative to vapor-compression refrigerators, which currently dominate the [...]

Hybrid Material May Outperform Graphene in Several Applications
Publicado emMaterials that are hybrid constructions (combining organic and inorganic precursors) and quasi-two-dimensional (with malleable and highly compactable molecular structures) are on the rise in several technological applications, such as the fabrication of ever-smaller optoelectronic devices. An article published in the journalPhysical Review Bdescribes a study in this field resulting from the doctoral research of Diana Meneses Gustin and Luís Cabral, both supervised by Victor Lopez Richard, a [...]ver notícia -
Bioluminescence Sensors Make New Approaches to Drug Discovery Possible
Publicado emCanadian researchers, working in partnership with Brazilian colleagues, have developed 13 bioluminescence sensors for use in testing the effectiveness of new medical drugs in the laboratory. The study, published in the journalScience Signaling, paves the way for new drugs to be tested and characterized. The biosensors are based on the action of G protein-coupled receptors (GPCRs), which are membrane-bound proteins involved in communication between cells. The researchers did not choose to [...]ver notícia -
Technology Developed in Brazil Will Be Part of the International Space Station
Publicado em 21 fevereiro 2019MIL/AERO A new version of equipment developed in Brazil—the Solar-T—will be sent to the International Space Station (ISS) to measure solar flares. It is estimated that the sun-THz, the new photometric telescope, will be launched in 2022 on one of the missions to the ISS and will remain there to take consistent measurements. DEEPER INSIGHTS Evaluating Oscilloscopes to Debug Mixed-Signal Designs The photometric telescope works at a frequency of 0.2 to 15 THz, which can only be measured [...]ver notícia -
Lithium-Air Batteries Can Store Energy for Cars, Houses and Industry
Publicado em 20 fevereiro 2019Current lithium ion battery technology will probably not be able to handle the coming decades' huge demand for energy. It is estimated that by 2050, electricity will make up 50 percent of the world's energy mix. Today, that rate is 18 percent. But installed capacity for renewable energy production is expected to increase fourfold. This will require batteries that are more efficient, cheaper and environmentally friendly. One of the alternatives being studied today in many parts of the world is [...]ver notícia -
World's Most Powerful Particle Accelerator Gets Chip Upgrade
Publicado em 18 abril 2018The Large Hadron Collider (LHC) reigns as the world’s most powerful particle accelerator. Its detection system used in one of the four major experiments, A Large Ion Collider Experiment (ALICE), is about to get a computer chip upgrade.The chips, dubbed SAMPA, were designed at Brazil’s University of São Paulo's Engineering School (Poli-USP). After extensive testing across the globe from a team of international experts, SAMPA was approved for large-scale fabrication. ALICE will receive all [...]ver notícia
